Description

  The present invention relates to a water treatment technology for sterilizing water used for ballast of ships (hereinafter sometimes referred to as “ballast water”) with a chlorine-based bactericide, and more specifically, a solid substance of chlorinated isocyanuric acid compound and fresh water. TECHNICAL FIELD The present invention relates to a water treatment method and a water treatment apparatus for sterilizing ballast water by injecting a chlorine-based bactericidal agent produced from the ballast water.

  The chlorinated isocyanuric acid compound is distributed in a solid state (Patent Document 1), and although it has a low solubility in water, it dissolves in water to generate hypochlorous acid, and serves as a source of chlorine having a bactericidal action. Is known to be. Therefore, chlorine-based germicides are used as germicides (Patent Document 2).

  On the other hand, this chlorine-based disinfectant is also used as a disinfectant for sterilizing water used for ship ballast. A typical example thereof is a ballast water treatment in which a chlorine-based bactericide manufactured in a ship is injected into water that is introduced from outside the ship and transferred to a ballast tank to sterilize the water. (Patent Document 3). For ballast water treatment using a chlorine-based bactericide made from a solid chlorinated isocyanuric acid compound as a raw material, the chlorine-based bactericide is produced by mixing and dissolving the chlorinated isocyanuric acid compound solid in seawater. Some (Patent Document 4) and some are manufactured by mixing and dissolving in fresh water instead of seawater (Patent Document 5).

JP 2003-89607 JP Japanese Patent Publication No. 63-63527 JP 2011-92899 JP JP 2012-254402 JP JP 2011-92898 JP

  Here, the solid substance of the chlorinated isocyanuric acid compound starts to self-decompose at 40° C. or higher, and the self-decomposition of the solid substance of the chlorinated isocyanuric acid compound significantly progresses at 45° C. or higher. When water generated by such self decomposition reacts with another chlorinated isocyanuric acid compound, chlorine gas is generated. Since chlorine gas containing water has a strong corrosive property and has an irritating odor, if chlorine gas is generated during the production of a chlorine-based disinfectant used for ballast water treatment onboard a chlorine-based disinfectant, It causes metal corrosion and material deterioration in pipes, measuring instruments, etc. that make up the device for manufacturing and supplying seawater, resulting in an increase in maintenance costs. Further, if the chlorine gas leaks to the outside of the device, it may cause discomfort and anxiety of the crew, and deteriorate the working environment on board. Therefore, when storing a solid substance of a chlorinated isocyanuric acid compound as a raw material of a chlorine-based bactericide used for ballast water treatment in a ship, it is usually placed in a container container that can be sealed and the temperature is less than 40 degrees Celsius ( Store in a place where the temperature is set to, for example, about 25 degrees Celsius, and take out the solid substance of the chlorinated isocyanuric acid compound from the container container every time it is necessary to manufacture the chlorine-based bactericide in the vessel, and temporarily store it in a hopper. The solid substance is transferred to a storage container, and the solid substance taken out from the temporary storage container is mixed with water and stirred to be dissolved in water.

  However, it is known that there are cases where the engine room of a ship or a place near the deck has a temperature of 40 degrees Celsius or higher, and the engine room of a ship sailing at low latitudes near the equator has a temperature of 55 degrees Celsius or higher. It is said to be. Even in such a case, there is no problem as long as the solid substance of the chlorinated isocyanuric acid compound is put in a container container that can be sealed and stored at a temperature of less than 40 degrees Celsius. However, when a chlorine-based germicide is manufactured onboard a vessel by dissolving the solid substance in water, (1) the chlorine-based germicide is transferred from the time when the solid substance is transferred from the container container into the temporary storage container. Until it is used as a raw material for a bactericide, it may be exposed to a temperature of 40 degrees Celsius or higher in the temporary storage container even temporarily. (2) A part of the solid matter in the temporary storage container may remain unused as a raw material for the chlorine-based bactericide, or may remain unused. Since the solid matter that should have been left may adhere slightly to the inner surface of the temporary storage container and remain, the residue is exposed to a temperature of 40 degrees Celsius or more in the temporary storage container. There may be cases where

  In both cases of (1) and (2) above, when it actually occurs, the solid substance of the chlorinated isocyanuric acid compound becomes a source of chlorine gas, which may cause metal corrosion or material deterioration or deterioration of the working environment on board. Cause.

  The present invention has been made in view of the above problems, when producing a chlorine-based disinfectant that is a disinfectant for seawater treatment, by suppressing the generation of chlorine gas, reduce the adverse effect of chlorine gas The purpose is to do.

Representative examples of the reducing agent are sodium sulfite or a hydrate thereof, sodium thiosulfate or a hydrate thereof, or an aqueous solution thereof.

<Principle and effect of the invention>
(1) First, in each of the first and thirteenth aspects of the present invention, when a chlorine-based bactericide is produced, a solid substance of a chlorinated isocyanuric acid compound that is a raw material thereof (hereinafter, referred to as “raw material solid substance”). A) is mixed with fresh water rather than seawater. This is because seawater contains a larger amount of chlorine components, and thus when the raw solid material is mixed with seawater, a larger amount of chlorine gas may be generated as compared with the case where it is mixed with fresh water.

  The fresh water can be covered with fresh water produced by using a seawater desalination apparatus mounted on a ship. In this way, it is not necessary to additionally install a tank for storing the fresh water in a narrow ship.

  In addition, according to each of the first and thirteenth aspects of the present invention, the upper limit of the temperature in the hopper or other temporary storage container in which the raw material solid material is temporarily stored (hereinafter referred to as “upper temperature limit in container”). Is set to 39 degrees Celsius, so that the temperature of the raw solid material that is stored in the temporary storage container or remains unused or adheres to the inner surface of the temporary storage container. , The temperature can be kept at 39 degrees Celsius or lower, which is lower than the self-decomposition temperature (about 40 degrees Celsius), and therefore the generation of chlorine gas from the temporary storage container can be suppressed, and the chlorine gas The adverse effect can be reduced.

  The upper limit of the temperature inside the container is set to 39 degrees Celsius instead of the self-decomposition temperature of the raw material solid (about 40 degrees Celsius) because the absolute value of the difference between the autolysis temperature and the upper limit of the temperature inside the container is small This is because if there is no margin in the temperature control range, for example, there may be a case where the temperature is temporarily 40° C. or higher due to a delay or overshoot of the temperature control. However, if it is necessary to more reliably prevent the self-decomposition of the raw material solids, the upper limit of the temperature inside the container is 2 degrees lower than the self-decomposition temperature of the raw material solids (about 40 degrees Celsius) (38 degrees Celsius). It is desirable to set the temperature to 3 degrees lower (37 degrees Celsius) or lower temperature (less than 37 degrees Celsius) if it is necessary to prevent more reliably.

  (2) In a raw material feeder (feeder) for supplying the raw material solids supplied from the hopper, which is a temporary storage container, to the solution manufacturing unit, a raw material feeder is configured to come into contact with the raw material solids. The wall surface of the member that exists is certainly present. For example, when the raw material feeder is equipped with a measuring mechanism for dividing the raw solid material into a small amount or a predetermined amount, the raw solid material may be included in the wall surface of the member constituting the measuring mechanism. There are things that come into strong contact with. In that case, there is a high possibility that raw material solids will remain on the wall surface or its surroundings. When such a residue exceeds about 40 degrees Celsius, it self-decomposes and becomes a source of chlorine gas. On the other hand, according to the fourteenth aspect of the present invention, since the temperature in the measuring mechanism is set to be equal to or lower than the upper temperature limit in the container, it is possible to suppress the generation of chlorine gas from the measuring mechanism. The adverse effect of chlorine gas can be reduced.

  (3) The raw material solids supplied from the hopper to the solution manufacturing unit may come into contact with the surface of the member forming the moving path thereof and adhere to and remain on the surface. When such a residue exceeds about 40 degrees Celsius, it self-decomposes and becomes a source of chlorine gas. On the other hand, according to the fifteenth aspect of the present invention, since the temperature in the moving path is set to be equal to or lower than the temperature upper limit in the container, it is possible to suppress the generation of chlorine gas from the moving path. It is possible to reduce the above-mentioned adverse effects of chlorine gas.

  (4) According to the second aspect of the present invention, when the temperature of the room, space or other place where the temporary storage container is installed (hereinafter referred to as “environmental temperature”) is less than 39 degrees Celsius, the environment Since it is not necessary to lower the temperature in the temporary storage container to a level below the temperature, energy consumption required for setting or controlling the temperature in the temporary storage container can be saved.

  In addition, when the case where the environmental temperature becomes 0 degrees Celsius or less is assumed, the temperature in the temporary storage container is not set to the environmental temperature or higher, but the lower limit of the temperature in the temporary storage container ( Hereinafter, it is preferable to set a “lower limit of temperature inside the container” and set the lower limit of temperature inside the container to a temperature higher than 0 degrees Celsius. When the lower limit of the temperature inside the container is less than 0 degree Celsius, the solid content of the raw material becomes less than 0 degree Celsius, and the freezing of fresh water that occurs when the solid material of the raw material and fresh water serving as a solvent is frozen to dissolve the solid material in fresh water. This is because there is a risk that it will interfere with the above or that it will take too long to dissolve. Further, for example, if an undershoot occurs during the control of the temperature in the temporary storage container, the temperature in the temporary storage container may be less than 0 degrees Celsius. If the temperature is set higher than the temperature, such a situation can be prevented.

  If there is a risk of undershoot below 0 degrees Celsius that may occur when controlling the temperature inside the temporary storage vessel, set the lower temperature limit inside the vessel to 2 degrees Celsius, which is 2 degrees higher than 0 degrees Celsius. It is more preferable to set the temperature to 3 degrees Celsius, which is higher than 0 degrees Celsius and 3 degrees Celsius.

  (5) According to the third aspect of the present invention, not only during charging of the solid raw material into the container for temporary storage but also before and/or after charging. Since the temperature inside the container is set below the upper limit of the temperature inside the container, the temperature of the raw material solids stored or remaining in the temporary storage container is less likely to exceed 40 degrees Celsius, and the temperature of the temporary solids is temporarily below 40 degrees Celsius. Even if the temperature is higher than 40 degrees Celsius, the time when the temperature is higher than 40 degrees Celsius can be shortened, and therefore, the generation of chlorine gas from the temporary storage container can be suppressed more effectively. It is possible to further reduce the above-mentioned adverse effects of chlorine gas.

  (6) In each of the fourth and sixteenth aspects of the present invention, the temperature of the fresh water before being mixed with the raw material solid is within a range of 5 degrees Celsius or more and 39 degrees Celsius or less (hereinafter, “within a specific temperature range”). It may be said that))).

  Here, FIG. 44 shows the relationship between the effective chlorine concentration and the dissolution time when sodium dichloroisocyanurate is dissolved in pure water, more specifically, the dissolution time to reach a predetermined effective chlorine concentration is It is a figure which shows the relationship which becomes short, so that temperature is high. In the case where sodium dichloroisocyanurate was dissolved in pure water at 3 degrees Celsius, the measurement was not performed because it took too long from the start of dissolution until the effective chlorine concentration of 7% was reached.

  The effective chlorine concentration required for use as a chlorine-based bactericide is about 7%. If it is assumed that the time required for the ship operator to accept the chlorine-based bactericide used for seawater sterilization is 30 minutes, the time from the start of dissolution to the achievement of an effective chlorine concentration of 7% is within 30 minutes. Is required. Then, according to FIG. 44, it is found that the temperature of pure water required to obtain a solution having an effective chlorine concentration of 7% within 30 minutes is 5° C. or higher. Based on this finding, the temperature of fresh water before being mixed with the raw material solids was set to 5°C or higher.

  On the other hand, when the temperature of the fresh water becomes 40 degrees Celsius or higher, the temperature of the raw material solid that comes into contact with the fresh water rises to reach the self-decomposition temperature or higher, and self-decomposition may generate chlorine gas. As described above, this chlorine gas can cause metal corrosion or material deterioration, and if it moves to a hopper or other container and leaks to the outside, it can cause deterioration of the work environment on board. In addition, the heat released from fresh water may adversely affect the setting of the temperature in the temporary storage container (this adverse effect is caused when the temporary storage container and fresh water flow paths are close to each other. Is especially noticeable). Therefore, the temperature of the fresh water before being mixed with the raw solid material was set to 39°C or lower.

  Thus, according to each of the above modes, (i) an aqueous solution having an effective chlorine concentration necessary as a bactericidal agent for treating ballast water can be obtained, and (ii) self-decomposition of a raw material solid in contact with fresh water is prevented. Since it is possible to control the temperature in the container in which the solid raw material is temporarily stored, the effects of the first and thirteenth aspects of the present invention become more remarkable.

  In addition, if importance is attached to the safety of the work environment on board, (a) the temperature of the fresh water is set to have a margin of 2 degrees or more above the upper limit which is the self-decomposition temperature (about 40 degrees Celsius) of the raw material solids, If it is safe to set the temperature to 38 degrees Celsius or lower, and if the safety of the work environment on board is emphasized, (b) the temperature of fresh water is set to have a margin of 3 degrees or more above the upper limit. It is safer to set it below 37 degrees Celsius. Needless to say, in the case of the former (a), the specific temperature range is within the range of 5 degrees Celsius or more and 38 degrees Celsius or less, and in the case of the latter (b), the specific temperature range is within the Celsius range. It is in the range of 5 degrees or more and 39 degrees Celsius or less.

  (7) In each of the fifth and seventeenth aspects of the present invention, since the raw material solids and fresh water are mixed within the specific temperature range, the temperature of the mixture also falls within the specific temperature range. If the temperature of the fresh water of the mixture is not lower than 5 degrees Celsius, if it is lower than that, the solubility of the raw material solid in fresh water is too low to obtain an aqueous solution having an effective chlorine concentration necessary as a bactericide, Or because it takes too long to obtain.

  On the other hand, when the temperature of the mixture becomes 40 degrees Celsius or higher, the temperature of the undissolved raw material solids in the mixture rises to the self-decomposition temperature or higher, and chlorine gas may be generated due to self-decomposition. If this chlorine gas moves to a hopper or other container and leaks to the outside due to metal corrosion or material deterioration, it may cause deterioration of the working environment on board. Further, the heat released from the mixture may adversely affect the setting of the temperature of the raw material solids in the temporary storage container (this adverse effect is not great, but the temporary storage container and the mixture). Relatively noticeable when and are close). Therefore, the temperature when mixing the raw material solids and fresh water is set to 39 degrees Celsius or less, placing importance on the safety of the working environment for producing a chlorine-based bactericide.

  Thus, according to each of the above modes, it is possible to prevent the self-decomposition of the raw material solids mixed with fresh water, and it becomes easier to set the temperature of the container in which the raw material solids are temporarily stored. The effects of the first and thirteenth aspects of the invention become more remarkable. In addition, if importance is attached to the safety of the work environment on board, the temperature when mixing the raw material solids and fresh water should be 38 degrees Celsius or less (that is, within a specific temperature range, 5 degrees Celsius or more, It is safe to set it within the range of 38 degrees Celsius or less, and set it to be below 37 degrees Celsius (that is, within a specific temperature range of 5 degrees Celsius or more and 37 degrees Celsius or less). Is safer.

  (8) According to the sixth aspect of the present invention, since the temperature of the chlorine-based bactericide formed by dissolving the raw material solid in fresh water is set to be within 39 degrees Celsius, the chlorine-based bactericide does not contain the raw material solid. Even if it is mixed in as it is dissolved, it is possible to suppress or prevent the generation of chlorine gas triggered by the self-decomposition of the undissolved raw material solid. Further, even if heat is transferred from the chlorine-based bactericide to the mixture of the raw material solids and fresh water, it is possible to prevent the undissolved raw material solids in the mixture from reaching 40°C or higher.

  (9) According to each of the seventh and twentieth aspects of the present invention, when the environmental temperature is high, the temperature in the temporary storage container can be reliably suppressed to the container internal temperature upper limit or less. In particular, according to each of the embodiments, it is possible to prevent the temperature in the temporary storage container from rising due to the influence of the increasing environmental temperature and to prevent the temperature in the container from rising.

  The reference temperature preset to 39 degrees Celsius or less is determined in consideration of the strength and degree of the influence of the environmental temperature on the temperature in the temporary storage container. For example, if the influence is large, the difference from 39 degrees Celsius is set large, and in the opposite case, the difference is set small.

  (10) According to each of the eighth and twenty-first aspects of the present invention, when the environmental temperature is low, the temperature in the temporary storage container can be reliably increased to the container internal temperature lower limit or more. In particular, according to each of the embodiments, it is possible to prevent the temperature in the temporary storage container from lowering below the lower limit of the internal temperature of the container due to the influence of the environmental temperature that tends to decrease.

  The reference temperature preset to 0 degrees Celsius or higher is determined in consideration of the strength and degree of the influence of the environmental temperature on the temperature in the temporary storage container. For example, if the influence is great, the difference from 0 degrees Celsius is set large, and in the opposite case, the difference is set small.

  (11) According to the ninth and twenty-third aspects of the present invention, when the temperature of the chlorine-based bactericide is high, the temperature in the temporary storage container can be reliably suppressed to the container internal temperature upper limit or less. In particular, according to each of the embodiments, it is possible to prevent the temperature in the temporary storage container from rising due to the influence of the increasing environmental temperature and to prevent the temperature in the container from rising.

  Further, when the temperature of the chlorine-based bactericide is high, the temperature of the fresh water before being mixed with the raw material solid matter can be surely suppressed to 39 degrees Celsius or less, whereby the temperature of the mixture of the raw material solid matter and the fresh water can be suppressed. It is possible to avoid a further increase in the temperature of the chlorine-based bactericide. It can also be avoided that the heat released from fresh water adversely affects the setting of the temperature in the temporary storage container.

  In addition, the reference temperature preset to 39 degrees Celsius or less is the presence or absence of the influence of the temperature of the chlorine-based bactericide on the temperature in the container for temporary storage and the temperature of the mixture of the raw material solid and fresh water, and the strength. Decide in consideration of the degree.

  (12) According to the seventh to ninth aspects of the invention and the twentieth, twenty-first and twenty-third aspects, the reference temperature is flexibly set according to the condition of the water treatment, and the water treatment method and the water treatment device are provided. Can be customized.

  (13) According to the eighteenth aspect of the present invention, the temperature in the tank is set within a specific temperature range, and therefore the temperature of the mixture of the raw material solids and fresh water in the tank falls within the specific temperature range. Therefore, it is possible to obtain the same effects as those obtained by the fifth and seventeenth aspects of the present invention.

  On the other hand, when the temperature in the tank reaches 40 degrees Celsius or higher, the mixture of the raw material solids and fresh water contained in the tank, and the undissolved raw material solids in the mixture rises to 40 degrees Celsius or higher. Chlorine gas is likely to be generated due to self-decomposition of undissolved raw material solids.

  Further, since the raw material solid solution is an aqueous solution formed by dissolving it in fresh water, that is, the chlorine-based germicide is also stored in the same tank, the raw material solid is not dissolved in the chlorine-based germicide in the process of stirring the mixture. There may be cases where it is left alone. In such a case, as the temperature in the tank becomes 40 degrees Celsius or higher, the chlorine-based bactericide becomes 40 degrees Celsius or higher, and the self-decomposition of undissolved raw material solids mixed therein is caused. Chlorine gas may be generated as a trigger.

  Furthermore, when the distance between the liquid level of the tank and the temporary storage container is short, the heat released from the contents of the tank reaches the temporary storage container, and the raw solid material present in the temporary storage container. There is also a risk of promoting the generation of chlorine gas triggered by the self-decomposition of.

  On the other hand, according to the eighteenth aspect of the present invention, since the temperature of the chlorine-based bactericide existing in the tank falls within the specific temperature range, the self-decomposition of the undissolved raw material solid is used as a trigger. Generation of chlorine gas can be prevented or suppressed.

  (14) In the nineteenth aspect of the present invention, the temperature of the chlorine-based bactericide discharged by the solid-liquid separator or the temperature in the solid-liquid separator is set within a temperature range of 5 degrees Celsius or higher and 39 degrees Celsius or lower. To be set.

  If the temperature in the solid-liquid separator or the temperature of the aqueous solution discharged by the solid-liquid separator is less than 10 degrees Celsius, the solubility of the raw material solids in fresh water is too low and the once dissolved chlorinated isocyanuric acid compound or this This is because the derived component may be precipitated.

  On the other hand, when the temperature inside the solid-liquid separation device or the temperature of the aqueous solution discharged by the solid-liquid separation device becomes 40 degrees Celsius or higher, the temperature of the undissolved raw material solids in the aqueous solution rises, and the self-decomposition temperature or higher Chlorine gas may be generated due to decomposition. This chlorine gas moves to the mixing section, from the mixing section to the hopper through the dissolution promoting section (particularly, the circulation piping path) connected to the solid-liquid separation device, leaks from the hopper to the outside, or the movement of the chlorine gas. If it leaks to the outside on the way, it will deteriorate the working environment on board. Further, in a situation where the temperature of the chlorine-based bactericide discharged by the solid-liquid separator or the temperature inside the solid-liquid separator is 40 degrees Celsius or higher, the heat released from the dissolution promoting unit is transferred to the mixing unit and the hopper. There is a possibility that it will spread, and it may promote the generation of chlorine gas triggered by the self-decomposition of the raw material solids existing in the mixing section and the hopper (This problem is not a big problem, but for example, a ballast water treatment device As a result of a more compact design, there may be cases where the solid-liquid separation device or the flow path of the aqueous solution from the solid-liquid separation device (including the circulation piping path) comes close to the mixing section or the hopper. ). Therefore, the temperature is set to 39 degrees Celsius or lower, placing importance on the safety of the working environment for producing a chlorine-based bactericide.

  Thus, according to the nineteenth aspect, it is possible to prevent the self-decomposition of undissolved raw material solids in the chlorine-based bactericide, and the effects of each of the first and thirteenth aspects of the present invention become more remarkable. Become.

  In addition, if importance is attached to the safety of the work environment on board, the temperature inside the solid-liquid separator or the temperature of the aqueous solution discharged by the solid-liquid separator is the upper limit of the self-decomposition temperature (about 40 degrees Celsius) of the raw material solids. Set to less than 37 degrees Celsius with a margin of 3 degrees or more from the upper limit if more emphasis is placed on safety so that there is a margin of 2 degrees or more to 38 degrees Celsius or less Preferably.

  (15) According to the twenty-second aspect of the present invention, when the temperature of the chlorine-based bactericide or the temperature in the solid-liquid separation device is high, the temperature of the fresh water before being mixed with the raw material solid matter is surely 39 degrees Celsius. The temperature can be suppressed to the following level, whereby a further increase in the temperature of the mixture of the raw material solid and fresh water and the temperature of the chlorine-based bactericide can be avoided. It can also be avoided that the heat released from fresh water adversely affects the setting of the temperature in the temporary storage container.

  The reference temperature preset to 39 degrees Celsius or less is a chlorine-based temperature for at least one of the temperature in the temporary storage container, the temperature of the mixture of raw material solids and fresh water, and the temperature of the chlorine-based germicide. It is determined in consideration of the influence of the temperature of the disinfectant or the temperature in the solid-liquid separation device, and the strength and degree of the influence.

  According to the twenty-second aspect of the present invention, it is possible to flexibly set the reference temperature according to the water treatment conditions and customize the water treatment method and the water treatment device.

  (16) Chlorine gas triggered by the self-decomposition of a raw material solid remains in the temporary storage container without being used for producing a chlorine-based germicide (the temporary storage container). (Including those that adhere to and remain on the inner wall surface of). Therefore, in order to sufficiently suppress the generation of chlorine gas, there may be a case in which it is not sufficient to set the temperature in the temporary storage container to 39° C. or lower only during the production of the chlorine-based bactericide.

  On the other hand, according to the tenth and twenty-third aspects of the present invention, not only during the production of the chlorine-based bactericide, but also for at least a certain period after the end of the production, and the eleventh and twenty-fifth aspects of the present invention. According to the form, not only during the injection into the water used as the ballast water of the chlorine-based sterilizing agent, for at least a certain period after the end of the injection, the temperature in the temporary storage container is set to 39 degrees Celsius or less, It is also possible to prevent or suppress the generation of chlorine gas which is triggered by the self-decomposition of the raw material solids remaining in the temporary storage container.

  In addition, in the case of each of the seventh and eighteenth aspects of the present invention, the “certain period” means a raw material that remains unused in the temporary storage container after the production of the chlorine-based bactericide is completed. Period until the amount of chlorine gas generated due to self-decomposition of solid matter decreases to such an extent that the effect of preventing or reducing the adverse effect of chlorine gas generated due to self-decomposition of the raw solid matter can be said to have been exerted Say. In the case of each of the seventh and eighteenth aspects of the present invention, the "certain period" means that the chlorine-based disinfectant remains unused in the temporary storage container after completion of injection into seawater. Until the amount of chlorine gas generated by the self-decomposition of the raw material solids decreases to the extent that the effect of preventing or reducing the adverse effect of the chlorine gas generated by the self-decomposition of the raw material solids can be said to have been exerted. Refers to the period. In any case, the “certain period” may be a short period or a long period.

  Moreover, since the period for setting the temperature in the temporary storage container to 39 degrees Celsius or less is "at least" a fixed period, it can be said that the effect of preventing or reducing the above-mentioned adverse effects of chlorine gas is exhibited. After that, the temperature in the temporary storage container may be continuously set to 39 degrees Celsius or lower.

  The time of manufacture of the fungicide may, but need not, overlap with the time of use.

  "At least a certain period after the production of the chlorine-based germicide in the tenth and twenty-third aspects of the present invention", and "End of injection of the chlorine-based germicide into seawater in the eleventh and twenty-fourth aspects of the invention. "At least for a certain period of time" often overlaps, but need not overlap.

  For example, the temperature in the temporary storage container is set to 39 degrees Celsius or less continuously from the first execution of the water treatment method according to the first embodiment of the present invention to the next execution. May be.

  (17) According to the twelfth aspect of the present invention, since the raw material solid matter is replenished in the container, the solid matter can be used up, that is, the end of the first stage can be postponed, and the seawater treatment can be continued. ..

  (18) According to the twenty-fifth aspect of the present invention, the temperature inside the hopper can be set or controlled using the temperature adjusting device.

  According to the twenty-sixth aspect of the present invention, it is rational because it is possible to cool or heat the periphery of the hopper together with air conditioning of the installation location of the hopper.

  In the twenty-seventh aspect of the present invention, since the heat insulating material is attached to the periphery of the hopper, even if the environmental temperature adversely affects or is likely to adversely affect the temperature setting in the hopper, eliminate the adverse effect. Or it can be reduced. In this embodiment, the heat insulating material attached to the periphery of the hopper may be in contact with at least a part of the outer surface of the hopper, and may be separated from the outer surface of the hopper without contacting the outer surface of the hopper. You may have.

  In the twenty-eighth aspect of the present invention, since the melting manufacturing section is installed in the space surrounded by the heat insulating material, the environmental temperature is different from the temperature in the melting manufacturing section or the temperature of the contents discharged from the container manufacturing section. Even if the setting is adversely affected or there is a possibility of such an adverse effect, the adverse effect can be eliminated or reduced. In this embodiment, the heat insulating material that surrounds the space where the melting and manufacturing unit is installed may be in contact with at least a part of the outer surface of the tank and the pipes that configure the melting and manufacturing unit. It may be separated from the outer surface.

  In a twenty-ninth aspect of the present invention, during the injection of the chlorine-based bactericide into the ballast water, and after or after the injection, the mixture of the raw material solid and fresh water is in contact with the solution production section. It does not dry because at least a part of the surface comes into contact with fresh water supplied from the water supply section. Therefore, according to this aspect, at least a part of the surface, it is possible to suppress or prevent the precipitation, deposition or solidification of the chlorinated isocyanuric acid compound which is a solute and its constituent components, and eventually maintenance inspection. The frequency can be reduced. In addition, since the raw material solid matter may remain in the solution manufacturing unit, the temperature of the fresh water supplied from the water supply unit and/or the temperature in the solution manufacturing unit after the fresh water is supplied are set to 39 degrees Celsius. It is desirable to set or control below.

  According to a thirtieth aspect of the present invention, a chlorine-based disinfectant which is not used for sterilization of ballast water and a mixture of raw solid and fresh water which is not used for production of chlorine-based disinfectant and is stored. Since it has a residue storage tank, it is possible to suppress or prevent the precipitation, deposition or solidification of the chlorinated isocyanuric acid compound or its constituent components that are solutes in the container constituting the water treatment device, the piping path, etc. Therefore, maintenance inspections can be reduced, and the frequency can be reduced.

  According to the thirty-first aspect of the present invention, the flow of the gas supplied from the gas supply device can suppress or prevent the moisture derived from the fresh water supplied to the solution manufacturing unit from reaching the hopper. it can.

  According to the thirty-second aspect of the present invention, when the raw material solids are not supplied from the hopper to the solution manufacturing unit, the movement route of the raw material solids between the hopper and the solution manufacturing unit is blocked by a mechanism such as a valve. Therefore, it is possible to suppress or prevent the moisture derived from the fresh water supplied to the solution manufacturing unit from reaching the hopper.

  According to the thirty-third aspect of the present invention, at least the side surface of the body of the hopper is surrounded by the heat insulating panel, so that the heat insulating structure of the hopper can be relatively easily constructed.

And mixing the raw material solid ms taken out from the container H with fresh water ws, and by stirring, a second step S2 having a step S21 for producing a chlorine-based germicide As which is an aqueous solution of a chlorinated isocyanuric acid compound. And, having a third step S3 having a step S31 of injecting the chlorine-based bactericidal agent As into the seawater Wo introduced from the outside of the ship VSL, the first step S1 is that the temperature Th in the container H is equal to or lower than the upper temperature limit in the container Has a step of setting (hereinafter referred to as "temperature setting step S12"). As described above, the upper limit of the temperature inside the container is 39 degrees Celsius, but this may be set to 38 degrees Celsius, 37 degrees Celsius, or a lower temperature in order to allow a wide range of temperature control.

  In the temperature setting step S12, as shown in FIG. 1B, in addition to setting the temperature Th in the container H to be equal to or lower than the upper temperature limit in the container, the temperature setting step S12 is set to be higher than the lower temperature limit in the container. It may be *. As described above, the lower limit of the temperature inside the container is higher than 0 degrees Celsius, but in order to allow a margin of temperature control, it may be set to 2 degrees Celsius, 3 degrees Celsius or higher.

  FIG. 2 is an explanatory diagram of Modification 1 of the basic form of the water treatment method according to the present invention. As shown in FIG. 2(a), the modification 1 has a preparation step, a first step S1, a second step S2, and a third step S3 as in the basic form, and the first step S1 is a temperature It has a setting step S12. However, unlike the basic form, the second step S2 is a step S22 of presetting the temperature Tws of the fresh water ws before mixing with the raw solid matter ms within a specific temperature range, mixing the raw solid matter ms and the fresh water ws. Performing the mixing within a specific temperature range when setting (more specifically, setting the temperature Tcs of the mixture Cs within the specific temperature range) Step S23, the temperature Tas of the produced chlorine-based germicide As is within the specific temperature range There is at least one step of the step S24 set inside. The temperature setting step S12 may be the temperature setting step S12*, as shown in FIG. 2(b).

  FIG. 3 is an explanatory diagram of a modified example 2 of the basic form of the water treatment method according to the present invention. As shown in FIG. 3(a), the second modification has a preparation step, a first step S1, a second step S2, and a third step S3, and the first step S1 has a temperature as shown in FIG. It has a setting step S12. However, unlike the basic form, the third step S3 has a step S32 of setting the temperature Tas* of the manufactured chlorine-based germicide As within a specific temperature range. The temperature setting step S12 may be the temperature setting step S12*, as shown in FIG.

  (2) When the raw material solids to be mixed with fresh water are subdivided into small amounts or predetermined amounts in the second stage S2, the temperature setting step S12 is a device for subdividing the subdivided solids (corresponding to a measuring mechanism described later). Step S12-1 of setting the temperature Th(fdr) in the device) to be equal to or lower than the upper limit of the temperature in the container. This step S12-1 may be a temperature setting step S12-1* of setting the temperature Th(fdr) to not less than the upper limit of the in-container temperature but also to be not lower than the lower limit of the in-container temperature.

  When the raw material solids to be mixed with fresh water in the second step S2 are taken out of the temporary storage container, the temperature setting step S12 is performed in the movement route of the raw material solids (for example, the raw material supply passage Cms described later). It may include a step S12-2 of setting the temperature Th (cms) of not more than the upper limit of the temperature inside the container. This step S12-2 may be a temperature setting step S12-2* in which the temperature Th (cms) is set to be equal to or lower than the upper limit of the in-container temperature or set to be equal to or higher than the lower limit of the in-container temperature.

  In the following description, unless otherwise specified, the steps S12-1 and S12-2 are represented by the step S12, and the steps S12-1* and S12-2* are represented by the step S12. Let them be represented. When treating the description of step S12 as the description of step S12-1 and step S12-2 or the description of step S12* as the description of step S12-1* and step S12-2*, the temperature Th is It should be read as the temperature Th(fdr) and the temperature Th(cms).

  (3) Generally, the basic form of the water treatment method according to the present invention has a preparation step, a first step S1, a second step S2 and a third step S3, as shown in FIG. 4(a). In addition, it is essential that the first step S1 has the temperature setting step S12. And this basic form may have at least one process of process S22, S23 and S24, and process S32 as a modification, and as shown in FIG.4(b), temperature setting process. S12 may be the temperature setting step S12*.

  (4) A typical example of the water treatment method according to the present invention is a ballast water treatment method using a chlorine-based bactericide. The ballast water treatment method can be described based on the above basic form and modifications as long as it corresponds to the water treatment method according to the present invention.

2) Description of Each Step Each step will be described with reference to FIG.

2.1) Preparation Step In the preparation step S0, a step S01 of preparing a container H for temporarily storing the raw material solid matter ms and a step S02 of preparing a solid matter (raw material solid matter) ms of the chlorinated isocyanuric acid compound. have. Step S01 is usually a step of preparing an apparatus that can be used for a long time or a plurality of times, and may be a step of newly installing the apparatus, or a step of preparing an existing apparatus. Good. Step S02 is a step of preparing a raw material solid ms that is a raw material of the chlorine-based bactericide As, and may have a step of replenishing the raw material solid ms.

  Step S01 means that when a container H is newly installed in the ship VSL, the newly installed container H is prepared, and when the container H is already installed in the ship VSL, the existing container H is installed. Means to prepare. The start time t[s01s] of the step S01 is not particularly limited, but the end time t[s01e] is the start time t[s1s] of the second step S2 at the latest.

  Step S02 is specifically a step of preparing a raw material solid ms at a predetermined place in the vessel VSL in preparation for charging the raw material solid into the container H, and for example, an air conditioning facility provided in the vessel VSL. This means storing the container containing the raw solid matter ms in the warehouse with. The start time t[s02e] of the step S02 is not particularly limited and is usually the time t[s01s] or later, and in many cases, the time t[so1e] or later. The step S02 needs to be completed before the start time t[s11s] of the storage step S11 described later at the latest.

  When the raw material solid ms is first stored in the container H and then replenished to the container H, the preparation of the raw material solid ms for the replenishment is completed before t[s11s], or t[s11s]. [s11e] must be completed by the time of supply before s11e].

2.2) First stage S1
(1) The first step S1 is a step of charging the raw material solid ms into the container H and temporarily storing it before taking it out of the container H (hereinafter referred to as "storage step S11"), and a temperature setting step S12. It is a stage which has. The temperature setting step S12 may be the temperature setting step S12*. As described above, the temperature setting step S12 may include the step S12-1 and the step S12-2, and the step S12-1 and the step S12-2 respectively include the step S12-1* and the step S12-2*. May be

  (2) The storage step S11 starts from the time t[s11s] when the raw material solids ms are loaded into the container H, and the raw material solids ms temporarily stored in the container H is removed from the container H. This is a process that ends at the time point t[s11e] when all of them are taken out. The charging of the raw material solids ms into the container H is performed by replenishing the raw material solids ms into the container H, that is, the raw material solids carried out before all the raw material solids ms in the container H are taken out of the container H. Includes ms loading. Therefore, the replenished raw material solid ms is included in the raw material solid ms temporarily stored in the container H.

  When continuing to store the raw material solid matter ms that is not used in the production of the chlorine-based sterilizer As in the container H, it is necessary to continue the storage step S11, so t[s11e] is It's late.

  (3) The start time point t[s12s] of the temperature setting step S12 or S12* is a time point before the start time point t[s11s] of the storage step S11. Since the temperature Th in the container H is preferably set to be equal to or lower than the upper limit of the temperature inside the container before the raw material solid ms is charged into the container H, t[s12s] is usually t[s11s ] Before.

  On the other hand, the end time point t[s12e] of the temperature setting step S12 or S12* is a time point after the end time point t[s11e] of the storage step S11. Because, after the storage step S11 is completed, the raw material solid matter ms adhering to the inner surface of the container H may remain, and the adverse effect of chlorine gas generated by the self-decomposition of the residue may occur. This is because that. However, the removal of the raw material solid matter ms remaining on the inner surface of the container H and the countermeasures against the chlorine gas that is the source of the residue have been successful, and the adverse effects of the chlorine gas have been reduced to below a certain level. In some cases, t[s12e] need not be after t[s11e].

  (4) When t[s12e] is after t[s11e], the temperature setting step S12 or S12* is continuously executed during the second step S2 and at least for a certain period after the execution. The third step S3 may be performed, and may be continuously performed for at least a certain period during and after the execution of the third step S3. Further, the temperature setting step S12 may be a step that is continuously executed until the start point of the next storage step S11 after the end of the storage step S11, and continues until the start point of the next temperature setting step S12 or S12*. It may be a process that is performed on a regular basis or a process that is always performed in principle.

2.3) Second stage S2
(1) The second step S2 is a step including a step S21 of manufacturing the chlorine-based germicide As by mixing the raw material solid ms taken out from the container H with fresh water ws and stirring the mixture.

  (2) When the raw material solid matter ms is taken out from the container H, it is desirable to take it out a plurality of times in a small amount or a predetermined amount. The reason is that if a large amount of raw material solids ms are taken out of the container H at a time and mixed with fresh water ws and stirred, the stirring effect does not spread, and undissolved raw material solids ms remain in a considerable amount. From the above, a small amount or a small amount of the raw material solid matter ms* is taken out multiple times, and each time it is taken out, it can be surely dissolved in the fresh water ws if mixed with fresh water ws and stirred. If this is repeated, This is because it is possible to reliably produce the required amount of the chlorine-based bactericide As having the effective chlorine concentration necessary as a bactericide for seawater treatment.

  (3) In the second step S2, the mixing of the raw material solid ms and the fresh water ws and the stirring of the mixture Cs may be performed simultaneously and/or in the same space, at different times and/or in different spaces. You may go in. For example, raw solid matter ms and fresh water ws may be charged into a tank, and mixing and stirring may be simultaneously performed by an impeller installed in the tank to produce the chlorine-based germicide As in the tank ( 11 to 16), raw material solid matter ms and fresh water ws are charged into a tank whose main purpose is mixing, and after mixing in the tank, the mixture Cs taken out from the tank is stirred. Alternatively, the chlorine-based bactericidal agent As may be produced by charging in an apparatus whose main purpose is solid-liquid separation and stirring in the apparatus (see FIGS. 19 to 23).

  (4) The second step S2 may include at least one of steps S22, S23, and S24. Steps S22, S23, S24 are all raw materials that remain in the mixture Cs or in the chlorine-based bactericide As while contacting with fresh water ws while maintaining the solubility of the raw material solid ms in fresh water ws above a certain level. This is a process mainly performed to suppress or prevent generation of chlorine gas triggered by self-decomposition of solid matter ms.

  (5) The step S21 is started in advance in consideration of the time when the execution of the third stage S3 is started. The start time t[s21s] is after the start time t[s11s] of the storage step S11 and after the start time t[s12s] of the temperature setting step S12. The end point t[s21e] of the step S21 is (i) when the production of the chlorine-based bactericide As required for the sterilization of the seawater Wo is finished, (ii) when the production becomes impossible, and (iii This is the earliest time when its production is no longer needed.

  (6) When step S22 is executed, its start time t[s22s] is the same time as or before the start time t[s21s] of step S21. The end point t[s22e] of step S22 is, in principle, the same point as t[s21e], but it may be a point after t[s21e].

  When the step S23 is executed, the starting time t[s23s] is the starting time of mixing the raw material solid ms and the fresh water ws. The end time t[s23e] of the step S23 is (i) the time when the mixing of the raw material solid ms and the fresh water ws necessary for producing the chlorine-based bactericide As necessary for sterilizing the seawater Wo is completed. , (Ii) when the mixing is no longer possible and (iii) when the mixing is no longer necessary. However, unless the adverse effect of chlorine gas generated upon self-decomposition of the undissolved raw material solids ms in the mixture Cs is reduced to a certain level or less, or unless another measure is taken to the chlorine gas, It is not necessary to end step S23 (rather, it is preferable to continue execution).

  When performing step S24, the starting time t[s24s] is usually the time when the chlorine-based bactericide As is started. The time point t[s24e] at the end of the step S24 is (i) when the production of the chlorine-based bactericide As is completed, (ii) when the production is disabled, and (iii) when the production is no longer necessary. Of these, the earliest. However, unless the adverse effect of chlorine gas generated by the self-decomposition of the undissolved raw material solids ms in the chlorine-based sterilizer As is reduced below a certain level, or other measures are taken against the chlorine gas. Unless t[s24e] is later.

  (7) In order to mix the raw solid matter ms and the fresh water ws within the specific temperature range, it is more effective to preset the temperature of the fresh water ws having a large specific heat within the specific temperature range, and the efficiency is also improved. good. Therefore, it is desirable that the start time point t[s22s] of the step S22 be a time point before the start time point t[s21s] of the step S21. When performing step S23, it is desirable to also perform step S22.

  (8) When the heat released from the fresh water ws may hinder the temperature Th of the raw material solid ms in the container H from being set below the upper limit of the internal temperature of the container, for example, a pipe through which fresh water ws circulates in the container H. If there is a possibility that the heat released from the pipe affects the temperature Th, it is desirable to execute the step S22 until the fear disappears. In that case, t[s22s] is preferably set to a point before t[s21s].

  When the heat released from the mixture Cs may prevent the temperature Th from being set below the upper temperature limit in the container, for example, the mixture Cs is close to the container H, and the heat released from the mixture Cs reaches the temperature Th. If there is a possibility of being affected, it is desirable to carry out step S23 until such fear is eliminated.

  When the heat released from the chlorine-based germicide As may hinder the execution of step 23 of setting the temperature Tcs of the mixture Cs within a specific temperature range, for example, the contact area between the chlorine-based germicide As and the mixture Cs is If the heat released from the chlorine-based bactericide As is likely to reach the mixture Cs, it is desirable to perform step 24 in addition to step 23.

  If the heat released from the chlorine-based germicide As may prevent the temperature Th from being set below the upper limit of the temperature in the container, for example, because the chlorine-based germicide As is close to the container H, the chlorine-based germicide When the heat released from As directly reaches the container H and may affect the temperature Th as a result, or the heat released from the chlorine-based germicide As reaches the mixture Cs and the heat released from the mixture Cs. When there is a risk that the gas will affect the container H and, as a result, the temperature Th, it is desirable to carry out step S24 until the risk disappears.

2.4) Third stage S3
(1) The third step S3 is a step including a step S31 of injecting the chlorine-based germicide As into the seawater Wo introduced from the outside of the ship VSL. In the case of ballast water treatment, in step S31, seawater Wo taken outside the ship is moved toward the ballast tank BT of the ship VSL in the process of moving the seawater Wo inside the ship toward the ballast tank BT. This corresponds to the step of performing sterilization treatment by injecting the chlorine-based sterilizer As.

  (2) The third step S3 may include the step S32. Step S32 is to maintain the solubility of the raw material solid ms in fresh water ws above a certain level and at the same time prevent the generation of chlorine gas triggered by the self-decomposition of the raw material solid ms remaining in the chlorine-based bactericide As. Is a process executed with the main purpose of.

  (3) The disclosure time t[s3s] in the third stage S3 can be said to be the time when the seawater Wo introduced from outside the ship VSL reaches the inlet of the chlorine-based germicide As.

  In the case of injecting all the chlorine-based sterilizer As into the seawater Wo, the end time t[s3e] of the third step S3 is almost the time when the introduction of the seawater Wo from the outside of the ship VSL is completed. However, if chlorine-based bactericide As remains without being injected into seawater Wo (for example, uninjected chlorine-based bactericide As remains in the pipe connected to the inlet) and is left as it is, if it is actually harmful, Unless the measures such as isolation and detoxification described later are taken, it is necessary to continue the execution of step S32, so t[s3e] is a later time point.

  (4) Although the step S32 is described as a step different from the step S24, like the step S24, it is a step of setting the temperature Tas* of the manufactured chlorine-based bactericide As within a specific temperature range. .. Depending on the configuration of the apparatus for performing the water treatment method according to the present invention, (i) part or all of the equipment/devices necessary for temperature setting in step S24 may be used in step S32. In some cases, (ii) the chlorine-based germicide As produced in the second stage S2 and the chlorine-based germicide As injected into the seawater Wo in the third stage S3 are present at the same location or at different locations. However, in the case where heat conduction from one side to the other occurs, the step S24 and the step S32 may be regarded as a single step in some cases. In the latter case (ii), at least a part of the execution period of step S32 overlaps with at least a part of the execution period of step S24.

3) Setting the reference temperature (1) In the temperature setting step S12, when the preset reference temperature Tm(h) of 39 degrees Celsius or less is exceeded, the temperature Th in the container H is lowered, You may perform control which sets temperature Th below the temperature upper limit in a container. Further, in the temperature setting step S12*, in addition to the same temperature control as in the temperature setting step S12, when the temperature falls below a preset reference temperature Tl(h) higher than 0 degrees Celsius, The temperature Th may be increased or decreased to control the temperature Th to be equal to or higher than the lower limit of the temperature inside the container.

  (2) When the second stage S2 includes the step S22, when the preset reference temperature Tm(ws) of 39 degrees Celsius or lower is exceeded, the temperature Tws of the fresh water ws is lowered and set in advance. When the temperature falls below the reference temperature Tl(ws) of 5 degrees Celsius or more, the temperature Tws of the fresh water ws may be increased to control the temperature Tws to fall within the specific temperature range.

  In the case where the second step S2 includes the step S23, when the preset reference temperature Tm (cs) of 39 degrees Celsius or less is exceeded, the temperature Tcs of the mixture Cs is lowered and preset. When the temperature falls below the reference temperature Tl(cs) of 5 degrees Celsius or higher, the temperature Tcs of the mixture Cs may be increased to control the temperature Tcs to be within the specific temperature range.

  When the second step S2 includes the step S24, when the preset reference temperature Tm(as) of 39 degrees Celsius or less is exceeded, the temperature Tas of the chlorine-based bactericide As is lowered and set in advance. When the temperature falls below the reference temperature Tl(as) of 5 degrees Celsius or higher, the temperature Tas of the chlorine-based germicide As may be increased to control the temperature Tas to fall within a specific temperature range.

  When the third step S3 includes the step S32, when the preset reference temperature Tm(as*) is exceeded, the temperature Tas* of the chlorine-based bactericide As is lowered and set in advance. When the temperature falls below the reference temperature Tl(as*) of 5 degrees or more, the temperature Tas* of the chlorine-based bactericide As may be increased to control the temperature Tas* within a specific temperature range.

  (3) The reference temperatures Tm(h), Tm(ws), Tm(cs), Tm(as) and Tm(as)* are set to, for example, 38 degrees Celsius, and the safety of the working environment on board is emphasized more. If so, for example, it may be set to 37 degrees Celsius (or a lower temperature). Depending on the case, the reference temperature value may be set in a dispersed manner (for example, the reference temperature Tm(h) is 36 degrees Celsius, the reference temperatures Tm(ws) and Tm(cs) are 37 degrees Celsius, and the rest of the reference temperatures are set. Temperatures Tm(as) and Tm(as)* to 38 degrees Celsius).

  (4) The reference temperature Tl(h) may be set to the same temperature as the lower limit of the temperature inside the container, and in some cases, may be set to a temperature higher than the lower limit of the temperature inside the container (for example, a temperature higher by 0.5 degrees).

  The reference temperatures Tl(ws), Tl(cs), Tl(as) and Tl(as)* are set to, for example, 6 degrees Celsius, and if there is concern about the effect of undershoot that may occur during temperature control, For example, it may be set to 7 degrees Celsius (or higher temperature). Depending on the case, the reference temperature values may be dispersed and set (for example, the reference temperature Tl(ws) is 7 degrees Celsius, the reference temperature Tl(cs) is 6 degrees Celsius, and the remaining reference temperatures Tm(as) are set. And Tm(as)* to 5 degrees Celsius).

4) Example 4.1) FIGS. 5 to 9 are explanatory views relating to Example 1 to Example 5 of the water treatment method according to the present invention, respectively. In all the examples, the reference temperature Tm(h) is 38 degrees Celsius unless otherwise specified.

(1) Steps S11, S12, S21 and S31 (Example 1)
In the first embodiment, as shown in FIG. 5, after the completion of the preparation step S0, the temperature setting step S12 → the storage step S11 → the step S21 → the step S31 are started in this order, and the storage step S11 → the step S21 → the temperature setting. The process S12 and the process S31 are ended in this order. Further, the end time point t[s11e] of step S11 and the end time point t[s21e] of step S21 are both times after the start time point t[s31s] of step S31.

  Therefore, in the first embodiment, (i) during the execution period of step S11, and (ii) during the execution period of step S21 and thereafter for a certain period (period from t[s21e] to t[s12e]), the temperature is The setting step S12 is executed, and thereby the temperature Th is set to the container internal temperature upper limit or less.

  In the first embodiment, steps S11 and S21 are simultaneously executed during the period from t[s21s] to t[s11e], and all steps S11, S21, and S31 are simultaneously executed during the period from t[s11e] to t[s31s]. To do. Such a method of executing each step is suitable for the case of injecting into the seawater Wo while manufacturing the chlorine-based bactericide As from the raw solid matter ms and the fresh water ws. In this case, the chlorine-based germicide As may be stored temporarily or may be directly injected into the seawater Wo without being stored temporarily.

(Example 2)
In the second embodiment, as shown in FIG. 6, after the preparation step S0 is finished, the temperature setting step S12 → the storage step S11 → the step S21 → the step S31 are started in this order, and the storage step S11 → the step S21 → the step S31. → The temperature setting step S12 is ended in this order. The start time t[s31s] of the step S31 is after the end time t[s11e] of the step S11, and the end time t[s21e] of the step S21 is after the start time t[s31s] of the step S31.

  Therefore, in the second embodiment, (i) during the execution period of step S11, (ii) during the execution period of step S21 and thereafter for a certain period (the period from t[s21e] to t[s12e]), and ( iii) The temperature setting step S12 is executed during the execution period of the process 31 and continuously for a certain period thereafter (the period from t[s31e] to t[s12e]), whereby the temperature Th is set to be equal to or lower than the upper limit temperature in the container. To do.

  In the second embodiment, similarly to the first embodiment, the steps S11 and S21 are simultaneously executed during the period from t[s21s] to t[s11e], and the steps S21 and S31 are performed during the period from t[s31s] to t[s21e]. Although executed at the same time, unlike the first embodiment, all of the steps S11, S21, S31 are not executed at the same time (particularly, the steps S11, S31 are not executed at the same time). However, the execution method of each step is suitable for the case where the chlorine-based bactericide As is produced from the raw material solid ms and the fresh water ws and injected into the seawater Wo as in the first embodiment. Also in this case, the chlorine-based germicide As may be temporarily stored, or may be directly injected into the seawater Wo without being temporarily stored.

(Example 3)
In Example 3, as shown in FIG. 7 and similarly to Example 1, after completion of the semi-preparation step S0, the temperature setting step S12->storage step S11->step S21->step S31 is started and stored in this order. The process S11→process S21→temperature setting process S12→process S31 are ended in this order. Further, the end time point t[s11e] of step S11 and the end time point t[s21e] of step S21 are both times after the start time point t[s31s] of step S31.

  Therefore, in Example 3, (i) during the execution period of step S11, and (ii) during the execution period of step S21 and thereafter for a certain period (period from t[s21e] to t[s12e]), the temperature The setting step S12 is executed, and thereby the temperature Th is set to the container internal temperature upper limit or less.

  In the third embodiment, similar to the first embodiment, the steps S11 and S21 are simultaneously executed during the period from t[s21s] to t[s11e], but unlike the first embodiment, all the steps S11, S21, and S31 are simultaneously executed. Nothing is done (in particular, steps S21 and S31 are not executed simultaneously). Such a method of performing each step is to temporarily store the chlorine-based germicide As produced from the raw solid matter ms and fresh water ws, and then take out the chlorine-based germicide As stored in the storage tank to seawater Wo. Suitable for injection cases.

(Example 4)
In the fourth embodiment, as shown in FIG. 8, the temperature setting step S12 is started before the end of the preparation step S0 (particularly step S02), and subsequently, the storage step S11→step S21→step S31 is started in this order. .. After the start of the temperature setting step S12, the step S02 is ended before the start of the storage step S11, and then the storage step S11→step S21→step S31→temperature setting step S12 is ended in this order. The start time point t[s31s] of step S31 is assumed to be after the end time point t[s21e] of step S21.

  Therefore, in the fourth embodiment, (i) during the execution period of step S11, (ii) during the execution period of step S21, and thereafter for a certain period (the period from t[s21e] to t[s12e]), and ( iii) The temperature setting step S12 is executed during the execution period of the process 31 and continuously for a certain period thereafter (the period from t[s31e] to t[s12e]), whereby the temperature Th is set to be equal to or lower than the upper limit temperature in the container. To do.

  In the fourth embodiment, as in the third embodiment, the steps S11 and S21 are simultaneously executed during the period from t[s21s] to t[s11e], but all the steps S11, S21, and S31 are not executed simultaneously (particularly, The steps S21 and S31 are not executed simultaneously). As in the case of the third embodiment, the method for performing each of these steps is to manufacture the chlorine-based germicide As from the raw solid matter ms and fresh water ws and then temporarily store the chlorine-based germicide As, and then store the chlorine-based germicide As in the tank. It is suitable for the case of taking out and injecting it into seawater Wo.

(Example 5)
The fifth embodiment is the same as the one in which the seawater treatment corresponding to the second embodiment is continuously performed twice or more. As shown in FIG. 9, the first temperature setting step S12 is performed from t[s12s]. Immediately after the period up to t[s12e], the second temperature setting step S12* is performed during the period from t[s12s]* to t[s12e]*, and the third and subsequent times are similarly performed continuously. .. In this case, t[s12e] and t[s12s]* as well as t[s12e]* and the starting time t[s12s]# of the third temperature setting step S12# are the same, and so on.

  In addition, when the temperature setting step S12 is performed a plurality of times in succession, it is possible to set a boundary point between adjacent temperature setting steps S12 (for example, t[s12e] and t[s12s]*, t[s12e]* and t[s12s]#) and a boundary point. The actual benefit of strictly setting the predecessor-successor relationship with the preparatory processes S0*, S0# after the second time and the storage processes S11*, S11# after the second time will be weak. In such a case, t[s02e]*, t[s11s]* and t[s12s]* in the second embodiment and t[s02e]#, t[s11s]# in the third embodiment. And t[s12s] # may be regarded as the same time point, and the same is true for the fourth time and thereafter.

  In the fifth embodiment, the temperature setting steps S12, S12*,... Are continuously executed for a certain period Pa after each of the second steps S2, S2*,. , Are executed for a certain period of time after the respective ends, and the temperature Th is set to be equal to or lower than the upper limit of the in-container temperature.

  When Example 5 is an example of a ballast water treatment method, a brief description will be given without considering the preparation steps S0, S0*, S0#,..., P1 in FIG. In the process of transferring the seawater Wo taken from the outside toward the ballast tank BT, the sterilization process is performed using the chlorine-based sterilizer As, P2 is that the ship VSL leaves the first port, Sail toward the second port, arrive at the second port, and then add a reducing agent to the seawater flowing out of the ballast tank BT at the second port and remain in the seawater. , A step of reducing free effective chlorine caused by the chlorine-based sterilizer As, performing a reduction treatment to detoxify the seawater to a level where outboard drainage is allowed, and preparing for the subsequent second sterilization treatment, P1* is the stage where the second sterilization process is executed at the second port, and P2* is when the vessel VSL leaves the second port and heads to another port (including the first port). And then arrives at the other port, and then at the other port, the reducing treatment is executed by adding the reducing agent to the seawater flowing from the ballast tank BT to the outside of the vessel, and the subsequent second sterilization treatment is performed. (Preparing for the subsequent steps is omitted in FIG. 9).

  If the seawater flowing from the ballast tank BT to the outside of the ship is already at a level at which outboard drainage is allowed without adding a reducing agent, the above reduction process is omitted.

(2) Steps S22, S23, S24 and S32 As described above, in the water treatment method according to the present invention, steps S22, S23, S24 and S32 are not essential steps. Therefore, when step S22 is not present, t[s2s] and t[s21s] and t[s2e] and t[s21e] are usually at the same time point, and when step S32 is not present, usually t [s3s] and t[s31s] and t[s3e] and t[s31e] are at the same time point.

On the other hand, when the processes S22, S23, S24, and S32 are performed in the first to fourth embodiments, the following settings are made.
(A) In any of the examples, the start time point t[s22s] of step S22 is set to before the start time point t[s21s] of step S21, and preferably t[s22s] is set to a time point before t[s21s]. To do.
(B) In any of the examples, preferably, the start time t[s32s] of step S32 is before the start time t[s31s] of step S31, and more preferably t[s32s] is greater than t[s31s]. The previous time. However, the chlorine-based germicide As produced in the second step S2 and the chlorine-based germicide As injected into the seawater Wo in the third step S3 are present at the same location or at different locations, but from one to the other. In some cases, the steps S24 and S32 can be regarded as a single step if the heat conduction of the above is performed. In such a case, there is little actual benefit of distinguishing the process S24 from the process S32, and t[s32s] can be regarded as the start time t[s24s] of the process S24.
(C) The end times t[s22e], t[s23e], and t[s24e] of steps S22, S23, and S24 are all preferably after the end time t[s21e] of step S21. Any two or all of t[s22e], t[s23e], and t[s24e] may be at the same time point, or may be at different time points.
(D) The end time t[s32e] of the step S32 is preferably a time point after the end time t[s31e] of the step S31.

4) Handling of residue (1) At t[s11e], if the remaining raw material solid ms is left without being taken out of the container H, chlorine gas generated by self-decomposition of the raw material solid ms is generated. It adversely affects the working environment on board. In particular, when the chlorine gas thus generated mixes with the water content in the container H, it exhibits strong corrosiveness and causes an irritating odor. Therefore, at the time of (i) t[s11e], the raw material solid matter ms does not remain in the container H and is exhausted for the production of the chlorine-based sterilizer As, so that the raw material solid matter ms is consumed. Strictly control the charging of the container H into the container H to prevent the above problems from occurring. (ii) At the time of t[s11e], the raw material solid ms remains in the container H. In the case or in preparation for such a situation, step S12 is continued, and if necessary, dehumidification in the container H is performed, and (iii) at time t[s11e] or early thereafter, the raw material remaining in the container H The solid matter ms is transferred to a container container for storage and stored, after being used up in the production of the mixture Cs or the chlorine-based germicide As, the mixture Cs or the chlorine-based germicide As is transferred to a separately prepared tank and isolated, It is desirable to take measures such as adding chemicals to render the tank harmless.

  (2) At time t[s23e], if the residual mixture Cs that has not been used for the production of the chlorine-based bactericide As is left to stand, a phenomenon occurs in which the mixture Cs solidifies due to evaporation of water ws. This phenomenon causes problems such as blockage of the pipe in which the mixture Cs remains, increase in pressure loss and other flow disturbances, malfunction of accessories such as valves and pumps attached to the pipe, and the following, second There is a possibility that it may be a factor that hinders the execution of step S2. In addition, chlorine gas generated by self-decomposition of the undissolved raw material solid ms remaining in the mixture Cs may adversely affect the working environment on board. If such a situation is concerned, at time t[s23e] or early thereafter, the residual mixture Cs is transferred to a separate tank for isolation, and a chemical is added in the tank to render it harmless. It is desirable to take measures such as.

  (3) At time t[s24e] or time t[s3e], if chlorine-based disinfectant As, which has not been injected into seawater Wo and remains unused as a disinfectant, is left as it is, the solvent water Due to the evaporation of the solute, the solute is concentrated, and the component of the chlorinated isocyanuric acid compound is deposited, deposited, and solidified. When the water temperature of the aqueous solution As decreases and the solubility of the chlorinated isocyanuric acid compound in water decreases, the components of the chlorinated isocyanuric acid compound that could not be completely dissolved under the decreased water temperature are precipitated, deposited, and solidified. Sometimes the phenomenon occurs. These phenomena cause troubles such as blockage of pipes, increase in pressure loss and other distribution obstacles, malfunction of accessories such as valves and pumps attached to pipes, and execution of the following third stage S3. May become a factor that hinders If such a situation is a concern, at the time of t[s24e] or t[s3e] or at an early stage, transfer the unused chlorine-based germicide As to a separately prepared tank. Therefore, it is desirable to take measures such as isolation by adding chemicals in the tank to render it harmless.

<Addendum>
(1) The temperature setting or control in the water treatment method according to the present invention does not have to be constantly executed. For example, setting or control of making the temperature in the temporary storage container equal to or lower than the upper temperature limit in the container does not need to be performed when the temperature in the temporary storage container is equal to or lower than the upper temperature limit in the container. Similarly, it is not necessary to set or control the temperature in the temporary storage container to be equal to or higher than the lower temperature limit in the container when the temperature in the temporary storage container is equal to or higher than the lower temperature limit in the container. Further, in both the fourth and sixteenth embodiments, it is essential to set the temperature of fresh water to 5 degrees Celsius or higher, but when the temperature of fresh water is 5 degrees Celsius or higher, No settings are required. In both the fifth and seventeenth embodiments, it is essential to set the temperature at which the raw material solid is mixed with fresh water to 5 degrees Celsius or higher, but the temperature at which the raw material solid is mixed with fresh water is When the temperature is 5 degrees Celsius or higher, it is not necessary to set it. In the eighteenth aspect, it is indispensable to set the temperature in the tank of the melting and manufacturing department to 5 degrees Celsius or higher, but when the temperature in the tank of the melting and manufacturing department is 5 degrees Celsius or higher, No settings are required. The nineteenth form has an essential configuration in which the temperature of the fresh water is set so that the temperature of the chlorine-based bactericide discharged by the solid-liquid separator or the temperature inside the solid-liquid separator becomes 5 degrees Celsius or higher. However, when the temperature is 5 degrees Celsius or higher, it is not necessary to set the temperature.

  (2) "5 degrees Celsius" is a numerically limited critical value of temperature in each of the fourth, fifth, and sixteenth to nineteenth modes. As described with reference to FIG. 44, this critical value is determined based on the assumption that the time required for the onboard worker to accept is 30 minutes as the production time of the chlorine-based bactericide used for seawater sterilization. However, the time that a ship operator can accept as the production time of a chlorine-based bactericide used for seawater sterilization varies depending on the situation. Therefore, for example, if the time that the inboard worker can accept is 15 minutes, the critical value is “10 degrees Celsius”, and if it is 60 minutes, the critical value is “3 degrees Celsius”. ..

The raw material solid matter ms is dissolved in fresh water ws (that is, the chlorine-based bactericide As is produced from the mixture Cs) and a dissolution promoting unit S[st]. However, since the mixing of the raw material solid ms and the fresh water ws and the stirring of the mixture Cs of both are performed in the mixing stirring tank Ts included in the solution manufacturing section S[pr], the mixing section S[mx] and the dissolution promoting section are included. The boundary with S[st] is ambiguous, and it is difficult to clearly distinguish the two.

And a raw material supply channel Cms arranged below the raw material supply device Fdr. The hopper H is provided with a storage unit (not shown) for storing the raw material solids ms and a raw material supply port Crf for charging the raw material solids ms into the storage unit, and a lower portion of the hopper H supplies the raw material. It is connected to the weighing mechanism Mvf that forms part of the machine Fdr. The storage part is a part existing in the hopper H and functioning as a container for containing the raw material solid matter ms.

  A lid is usually attached to the end opening of the raw material supply port Crf.When the raw material solid ms is charged or replenished in the storage section of the hopper H, the lid is removed and the supply pipe ( (Not shown). The replenishment pipe may be a tubular body extending from the storage chamber of the raw material solid ms arranged above the hopper H, in which case, the worker supplies the raw material solid ms from the storage chamber to the replenishment pipe and Through the raw material supply port Crf, it is possible to charge or supply to the storage part of the hopper H. Further, the supply pipe may be a connection pipe having a stretchable bellows portion.

  The raw material feeder Fdr is configured to subdivide the raw material solids ms moved from the storage section of the hopper H into a small amount or a predetermined amount, and transfer the subdivided raw material solids ms* to the raw material supply path Cms. There is.

  The raw material supply path Cms supplies the raw material solid matter ms* moved from the raw material feeder Fdr into the mixing stirring tank Ts through the discharge opening at the lower end.

  In general, the raw material solid ms is charged or replenished into the hopper H from the raw material replenishing port Crf, is stored in the storage part of the hopper H, moves from the lower part of the storage part to the raw material supply device Fdr, and the raw material supply device Fdr. The raw material solid matter ms* is divided into small pieces, and the raw material solid matter ms* is moved to the raw material supply passage Cms and charged into the mixing and stirring tank Ts through the raw material supply passage Cms.

  1.2.2) FIG. 12 is an explanatory view of the raw material feeder Fdr, and a partial cross-sectional view of the main part of the raw material feeder Fdr within the ellipse of the alternate long and short dash line shown in FIG. 12(b).

  (1) The raw material feeder Fdr has a measuring mechanism Mvf for dividing the raw material solid matter ms moved from the storage section of the hopper H into a small amount or a predetermined amount, and a driving unit Ss[mga] for driving the measuring mechanism Mvf. The raw material solid matter ms* subdivided by the measuring mechanism Mvf is moved to the raw material supply path Cms.

  As shown in FIG. 12( b ), the weighing mechanism Mvf is a raw material solid that has descended from the storage section of the hopper H into a housing Ymvf including a housing upper portion Ym1, a housing lower portion Ym2, and a housing side portion Ym3. Inlet Din for passing the object ms, a pedestal having a horizontal main surface Bt, a rotary table Rtf that rotates on the main surface Bt of the pedestal, a rotary shaft Axf that rotates with the rotary table Rtf, and the raw material that has been subdivided A discharge port Dout for moving the solid matter ms* to the raw material supply path Cms is provided. In addition, in FIG. 12B, reference numeral Ha is an inclined surface that forms the bottom of the storage portion of the hopper H in a funnel shape toward the receiving port Din.

  The turntable Rtf has at least one hole Op that penetrates in the thickness direction above and below. The hole Op may be a group of a plurality of holes. The receiving port Din is a through hole formed in the housing upper part Ym1 for communicating the inside of the hopper H and the inside of the housing Ymvf, and is therefore arranged above the turntable Rtf. The discharge port Dout is a through hole formed in the lower part Ym2 of the casing for communicating the inside of the casing Ymvf with the raw material supply passage Cms, and is therefore arranged below the rotary table Rtf. The rotation axis Axf is a rotation axis that penetrates the lower portion Ym2 of the housing and is also a part of the drive unit Ss[mga] as described later.

  (2) FIG. 13 is an explanatory diagram of the principle of the measuring mechanism Mvf. The holes (or individual holes) Op provided in the rotary table Rtf form a recess U in the inner wall surface together with the main surface Bt of the pedestal except when it is at the position of the discharge port Dout (see FIG. 13A). At the position of the discharge port Dout, the recess U is not formed to communicate with the discharge port Dout (see FIG. 13B). Therefore, the recess U can accommodate a fixed amount of the raw material solid ms (raw material supply ms*) that has descended from the receiving port Din, and can be moved to the discharge port Dout as the rotary table Rtf rotates. , A fixed amount of original solid matter ms* can be discharged to the discharge port Dout and moved to the raw material supply path Cms (see FIG. 12B).

  14A and 14B are explanatory views of main parts of the weighing mechanism Mvf, FIG. 14A is a plan view of the rotary table Rtf, and FIG. 14B is a plan view of the main surface Bt of the pedestal. The rotary table Rtf shown in FIG. 14(a) includes a total of four holes Op1, Op2, Op3, Op4 arranged every quarter circle (90 degrees) along the circumferential direction (rotational direction). is doing. Each of the four holes has a substantially fan shape, but the number, shape, size, position, arrangement, etc. of the holes Op are not limited to those shown in FIG. For example, at least one of the four holes Op1, Op2, Op3, Op4 may be a group of holes.

  The inlet Din and the outlet Dout are arranged at positions displaced by 180 degrees around the rotation axis of the rotary table Rtf (see FIG. 14B). Therefore, the holes Op1, Op2, Op3, and Op4, respectively, except when the holes Op1, Op2, Op3, and Op4 are located at the position of the discharge port Dout, form the recesses U1, U2, U3, and U4 that open upward together with the main surface Bt of the base. When it is at the position of the discharge port Dout, it communicates with the discharge port Dout.

  When the hole Op1 is located directly below the receiving port Din, a certain amount of the raw material solids ms* falling from the receiving port Din is accommodated in the recess U1. Next, the rotary table Rtf is rotated to move the concave portion U1, and accordingly, the fixed amount of the raw material solid matter ms* is moved. The rotary table Rtf is rotated 180 degrees from the position of the receiving port Din so that the hole Op1 reaches the position of the discharging port Dout. As a result, the hole Op1 communicates with the discharge port Dout, so that the certain amount of the raw material solid matter ms* accommodated in the recess U1 can be lowered to the discharge port Dout and moved to the raw material supply path Cms.

  After being housed in the recess U1, each time the rotary table Rtf is rotated 90 degrees, the recess U2, the recess U3, the recess U4, the recess U1,... Can be located in that order directly below the receiving port Din. A fixed amount of raw material solid matter ms* of the raw material solid matter ms descending from the inlet Din can be accommodated in the order of the concave portion U2, the concave portion U3, the concave portion U4, the concave portion U1,. After moving from the recess U1 to the raw material supply path Cms through the discharge port Dout, every time the rotary table Rtf is rotated by 90 degrees, Op2, Op3, Op4, Op1,... Are connected to the discharge port Dout in that order. , A fixed amount of the raw material solids Ms* accommodated in each of the recessed portion U2, the recessed portion U3, the recessed portion U4, the recessed portion U1,... Can be lowered to the discharge port Dout and moved to the raw material supply passage Cms.

  Generally, according to this measuring mechanism Mvf, the raw material compound ms moving from the storage part of the hopper H is quantified or subdivided into a small amount, and the subdivided raw material compound ms* is divided into a plurality of times and fed to the raw material supply path Cms. Can be moved.

  The measuring mechanism Mvf may be provided with a lid for closing the receiving port Din when necessary, or may be provided with a lid for closing the discharge port Dout when needed (none of the lids is shown).

  As shown in FIG. 12B, the measuring mechanism Mvf may be provided with a pair of upper and lower blades Bru and Brd for crushing the raw material solid matter ms moving to the receiving port Din and adjusting the particle size. . The lower blade Brd is fixed to the housing side part Ym3, and the upper blade Bru rotates together with the rotation axis Axf, so the raw material solid ms having an unexpectedly large particle size is sandwiched between the upper and lower blades Bru and Brd. It is crushed by the shearing force that it receives when it breaks into small particles. However, if it is not necessary to place a fear that there is an unexpectedly large raw material solid ms having a particle size in the hopper H, a particle size adjusting mechanism such as the blades Bru and Brd is not necessary. ..

  The measuring mechanism Mvf may include a discharge support mechanism that discharges the raw material solid matter ms* from the hole Op of the rotary table Rtf and assists the movement to the discharge port Dout. FIG. 15 is an explanatory diagram of an example of the discharge support mechanism. When the hole Op communicates with the discharge port Dout, the discharge support mechanism shown in FIG. 15 causes the gas s to be jetted downward from above the hole Op, and the pressure of the gas A1 at that time causes It is a mechanism for moving from the hole Op to the raw material supply path Cms through the discharge port Dout. A typical example of the gas A1 is dehumidified air. If the ejection range of the gas A1 is widened, fine particles of the raw material solid ms attached to the wall surface of the hole Op or the surface of the rotary table Rtf can also be moved to the raw material supply path Cms. The gas A1 that has moved to the dissolution production section S[pr] through the raw material supply path Cms is discharged to the outside by the exhaust means provided in the dissolution production section S[pr].

  (4) The drive mechanism Ss[mga] is for generating the rotational driving force of the rotary shaft Axf and the rotary shaft Axf to which the rotary table Rtf is attached directly or via a known power transmission mechanism such as a gear or a belt. The motor Mth and a known power transmission mechanism Gbx such as a gear and a belt for transmitting the driving force from the motor Mth to the rotation shaft Axf. When the rotation shaft of the motor Mth is coaxially attached to the rotation shaft Axf, the device used for the attachment is the driving force transmission mechanism Gbx. By controlling the operation of the motor Mth, the operation of the rotary table Rtf can also be controlled.

  As shown in FIGS. 12 and 15, each casing of the power transmission mechanism Gbx and the motor Mth, which is a part of the drive mechanism Ss[mga], is arranged outside the casing of the weighing mechanism Mvf. Has been done.

1.3) Water supply unit S[ws]
The water supply unit S[ws] includes a supply source (not shown) of fresh water ws and a water supply conduit Cws for supplying fresh water ws from the supply source into the mixing and stirring tank Ts. The water supply conduit Cws opens in the mixing and stirring tank Ts, a discharge opening for discharging the fresh water ws, and a pump for driving the transfer of the fresh water ws from the supply source of the fresh water ws to the discharge opening (shown in the drawing). (Not shown) and a valve (not shown) for switching between transfer and stop of fresh water ws.

  Fresh water ws can be covered by fresh water produced using a seawater desalination device onboard a ship.

1.4) Sterilizer injection part S[is]
The disinfectant injection section S[is] is arranged at the lowest part of the lower part Rbp of the mixing stirring tank Ts, and the discharge port Dbp for discharging the chlorine-based germicide As from the mixing stirring tank Ts and the ballast water intake. A disinfectant injection port Is that is opened in the service pipe and that injects a chlorine-based disinfectant As into the circulating seawater Wo, and a disinfectant pipe path Ls that connects the discharge port Dbp and the disinfectant injection port Is are provided. The disinfectant pipe line Ls is a valve Vbp for switching the movement and stop of the chlorine-based disinfectant As from the inside of the mixing and stirring tank Ts to the discharge port Dbp, and the disinfectant injection port Is to the ballast water intake pipe line Lf. It is equipped with a valve Vs for switching the injection and stop of the chlorine-based germicide As, and a pump Ps that drives the movement of the chlorine-based germicide As along the germicide piping path Ls downstream of the valve Vbp and upstream of the valve Vs. There is.

  The pump Ps, when the chlorine-based germicide As is present in the mixing stirring tank Ts and both valves Vbp and Vs are both open, helps discharge the chlorine-based germicide As from the mixing stirring tank Ts. The chlorine-based germicide As is poured into the water Wo from the germicide inlet Is.

  The disinfectant piping path Ls shown in FIG. 10 is discharged from the mixing agitating tank Ts although the illustration between the valve Vbp and the pump Ps and between the pump Ps and the valve Vs is omitted. It may be provided with a tank for temporarily storing the mixture Cs to be mixed, and a return piping path for returning such mixture Cs to the mixing and stirring tank Ts.

1.5) Operation In the water treatment device D1 shown in FIG. 10, first, the raw material solid ms is supplied from the hopper H and the fresh water ws is supplied from the water supply conduit Cws into the mixing and stirring tank Ts, respectively. A mixture Cs of thing ms and fresh water ws is received. Then, the mixture Cs is stirred by the impeller Ip in the mixing stirring tank Ts, whereby the mixing of the raw material solid ms and the fresh water ws and the dissolution of the raw material solid ms into the fresh water ws proceed, and the chlorine-based germicide As is produced. It The chlorine-based sterilizer As produced in the mixing and stirring tank Ts is discharged from the mixing and stirring tank Ts, moves through the sterilizing agent piping path Ls, and flows from the bactericidal agent inlet Is through the ballast water intake piping path Lf. Injected into water Wo to sterilize water Wo. After passing through the mixer Mxs, the water Wo into which the chlorine-based sterilizing agent As has been injected moves toward the ballast tank BT as the sterilizing agent-injected water Ws, and is stored in the ballast tank BT.

1.6) Relationship with Each Step Step S01 is a step of preparing the water treatment device D1, especially the hopper H, and Step S02 is a step of preparing the raw solid matter ms to be charged into the hopper H. The step S11 is executed in the hopper section S[hp], the step S21 is executed in the solution manufacturing section S[pr], particularly in the mixing and stirring tank Ts, and the step S31 is executed in the bactericide injection section S[is].

2) Example (Example-A)
2. A. 1) Features of Configuration FIG. 16 is an explanatory diagram of an embodiment-A of the water treatment device D according to the present invention. The configuration and operation of the example-A are basically the same as those of the water treatment device D1 shown in FIG. 10, except that the hopper section S[hp] is provided with a temperature setting mechanism.

2. A. 2) Temperature setting mechanism provided in the hopper S[hp] The temperature setting mechanism provided in the hopper S[hp] is provided with heat insulating materials InsH and InsH* that cover the outer surface of the hopper H without a distance. The outer surfaces of the raw material supply device Fdr and the raw material supply passage Cms are not covered with a heat insulating material. There is no heat insulating material between the housing of the measuring mechanism Mvf and at least part of the housing of the drive mechanism Ss[mga] (at least part of the housing of the motor Mtf and/or the housing of the power transmission mechanism Gbx). .. The heat insulating material InsH* is a heat insulating material that covers the upper outer surface of the raw material supply port Crf with no distance, and is configured to be removable when introducing or replenishing the raw material solid matter ms from the top opening. Has been done.

  According to this temperature setting mechanism, the heat transfer between the outer surface of the hopper H, that is, the inside of the hopper H and the outside is blocked by the heat insulating materials InsH and InsH*, so that when the environmental temperature is higher than the upper limit of the temperature inside the container, When the temperature is lower than the lower limit of the in-container temperature, the influence of the environmental temperature can be less likely to reach the temperature Th in the hopper H.

  The temperature Th in the hopper H is influenced by the temperature of the raw material feeder Fdr adjacent to the hopper H, and the temperature of the raw material feeder Fdr is influenced by the environmental temperature, and thus indirectly influenced by the environmental temperature. Therefore, when it is necessary to remove more of the influence of the environmental temperature from the temperature Th in the hopper H, the temperature setting mechanism provided in the hopper S[hp] may be modified according to the degree of the necessity. It is desirable to be deformed like 1 to 5.

  When the gas A1 is supplied into the measuring mechanism Mvf by using the discharge support mechanism and circulates through the raw material supply path Cms (see FIG. 15), the temperature of the gas A1 is set such that the ambient temperature is equal to or lower than the upper limit of the temperature inside the container. .. Further, desirably, the humidity of the gas A1 supplied into the measuring mechanism Mvf is set as low as possible. As a result, it is possible to reduce the risk that the raw material solid matter ms remaining in the measuring mechanism Mvf or the raw material supply path Cms becomes a source of chlorine gas.

(A-1) Modification 1
17A and 17B are explanatory views of a modified example 1 of the temperature setting mechanism included in the hopper unit S[hp], FIG. 17A is a front view thereof, and FIG. 17B is a side view thereof. ..

  In the modified example 1, as shown in FIG. 17, the heat insulating material Ins1 that surrounds the outer surface of the hopper H at a distance and the upper outer surface of the (ii) raw material supply port Crf are not separated from each other. It is provided with a heat insulating material Ins1* for covering and (iii) a temperature adjusting device CL1 for adjusting the temperature in the space W[hi] between the outer surface of the hopper H and the heat insulating material Ins1.

  The heat insulating material Ins1 reaches the boundary between the hopper H and the weighing mechanism Mvf, but does not surround or cover the side surface of the weighing mechanism Mvf). In addition, heat insulation is provided between the housing that houses the weighing mechanism Mvf and at least part of the housing of the drive mechanism Ss[mga] (at least part of the housing of the motor Mtf and/or the housing of the power transmission mechanism Gbx). There is no wood.

  The temperature control device CL1 is a device having both a cold heat generating function and a hot heat generating function. However, the heat generation function is not essential depending on the type of ship, route, installation location of hopper H, and other conditions.

  A typical example of a device that exhibits a cold heat generation function is a cold heat generator that applies the principle of a vortex tube. This cold heat generating device introduces the cold air generated outside the heat insulating material Ins1 into the space W[hi] and moves it along the outer periphery of the hopper H (for example, in a circulating manner), in the process of which the space W[hi] The air in [hi] is cooled and then discharged from the space W[hi].

  A typical example of a device that exhibits a heat generation function is a heat generation device including a heat transfer heater. In this heat generator, a heat transfer heater is installed in the space W[hi] and heat is generated by the heat transfer heater to directly heat the air in the space W[hi], or a heat transfer heater installed outside the hopper H is used. The hot air generated by the heat heater is introduced into the space W[hi] and moved along the outer periphery of the hopper H (for example, in a circulating manner), in the process of warming the air in the space W[hi], After that, it is discharged from the space W[hi]. In the case of using the cold heat generator applying the principle of the vortex tube, warm air generated at the same time as cold air in the cold heat generator may be used to warm the air in the space W[hi].

  The temperature control device CL1 can be configured to set or control the temperature in the hopper by using a heat carrier substance that has exchanged heat with a heat source provided in the ship or a heat source outside the ship. In that case, the heat source provided in the ship may be seawater taken from the outside of the ship, may be a heat storage material or heat carrier material that has exchanged heat with the seawater, or may be an air conditioner. Typical examples of the heat transfer substance are air and water, and typical examples of the heat storage substance are water.

  According to the modified example 1, since the space W[hi] is provided in addition to the heat insulating material Ins1, the influence of the environmental temperature on the temperature Th in the hopper H is smaller than that in the hopper portion shown in FIG. , Can be suppressed or prevented more effectively.

  Further, according to the temperature control device CL1, (a.1) when the ambient temperature is higher than the temperature Th in the hopper H, the cold heat generation function is activated to lower the temperature in the space W[hi] to a temperature lower than the ambient temperature. So that the temperature Th can be maintained or lowered, and (a.2) when the environmental temperature is lower than the temperature Th, the heat generation function is activated to change the temperature in the space W[hi]. It can be set to be higher than the ambient temperature, so that the temperature Th can be maintained or raised. Therefore, according to the first modification, the operation of the cold heat generating function and the operation of the warm heat generating function are appropriately switched to adjust the temperature of the space W[hi] so that the temperature Th is equal to or lower than the upper temperature limit in the container. It can be set above the lower temperature limit.

  In any of the cases (a.1) and (a.2) above, the space W[hi] set to a temperature different from the environment temperature is higher than the space W[hi] having the same temperature as the environment temperature. , Becomes a more effective heat transfer barrier. Therefore, according to the first modification, it is possible to more effectively suppress or prevent the influence of the environmental temperature on the temperature Th.

  The upper outer surface of the raw material supply port Crf may not be covered with the heat insulating material Ins1*, but the upper outer surface may be surrounded by the heat insulating material Ins1 at a distance. In that case, the space W[hi] is connected to the space between the upper outer surface of the raw material supply port Crf and the heat insulating material Ins1, so that the effect of adjusting the temperature of the space W[hi] is also applied to the latter space. Can be exerted.

  Even if the temperature Th in the hopper H is indirectly influenced by the environmental temperature via the raw material feeder Fdr, the variation 1 is sufficient if the influence is not so large. However, when the effect cannot be ignored, it is appropriate to adopt another modification.

(A-2) Modification 2
18A and 18B are explanatory views of a modified example 2 of the temperature setting mechanism included in the hopper unit S[hp], FIG. 18A is a front view thereof, and FIG. 18B is a side view thereof. .. As shown in FIG. 18, the modified example 2 includes a temperature adjusting device CL1* that adjusts the temperature Th in the hopper H. The rest of the configuration of the second modification is the same as that of the first modification, so the description thereof is omitted.

  A typical example of the temperature control device CL1* for lowering the temperature Th in the hopper H is a cold air generating device that applies the same vortex tube principle as that of the temperature control device CL for lowering the temperature of the space W[hi]. Is. Further, a representative example of the temperature adjusting device CL1* for increasing the temperature Th in the hopper H is a heat generating device including a heat transfer heater, which is the same as that of the temperature adjusting device CL for increasing the temperature of the space. In the case of using the cold heat generating device applying the principle of the vortex tube, the warm air generated at the same time as the cold air in the cold air generating device may be used to raise the temperature of the space W[hi].

  The temperature control device CL1* can be configured to set or control the temperature in the hopper by using a heat carrier substance that exchanges heat with a heat source provided in the ship or a heat source outside the ship. .. In that case, the heat source provided in the ship may be seawater taken from the outside of the ship, may be a heat storage material or heat carrier material that has exchanged heat with the seawater, or may be an air conditioner. Typical examples of the heat transfer substance are air and water, and typical examples of the heat storage substance are water.

  In the first modification, the temperature Th in the hopper H is controlled or set only by the temperature adjustment device CL1. On the other hand, in the modified example 2, the temperature Th is controlled or set by the two temperature adjusting devices CL1 and CL1*. Therefore, according to the second modification, the temperature Th can be controlled or set more effectively than the first modification. Therefore, when the temperature Th is affected by the environmental temperature via the raw material feeder Fdr, it is appropriate to adopt the modified example 2 rather than the modified example 1.

  On the other hand, the modified example 2 is similar to the modified example 1 in that the housing that houses the weighing mechanism Mvf and at least part of the housing of the drive mechanism Ss[mga] (the housing of the motor Mtf and/or the housing of the power transmission mechanism Gbx). At least part of the body) does not have insulation. In such a case, the heat received from the outside by the motor Mtf and/or the power transmission mechanism Gbx or the heat generated inside is released toward the adjacent measuring mechanism Mvf, and the heat radiation is transmitted through the measuring mechanism Mvf. It may be transmitted to the hopper H and affect the temperature Th. Therefore, when the influence cannot be ignored, it is desirable to adopt another modification.

(A-3) Modification 3
19A and 19B are explanatory views of a modified example 3 of the temperature setting mechanism included in the hopper unit S[hp], FIG. 19A is a front view thereof, and FIG. 19B is a side view thereof. , (C) and (d) of FIG. 19 are partial enlarged views of Modification 3 shown in (a) and (b) of FIG. 19, respectively. 20A and 20B are partially enlarged views of the derivative form 1 of the modified example 3, which are a front view and a side view, respectively. 21A and 21B are partially enlarged views of the derivative form 2 of the modified example 3, which are a front view and a side view, respectively. 22A and 22B are partially enlarged views of the derivative form 3 of the modified example 3, which are a front view and a side view, respectively.

  In the modified example 3, as shown in FIG. 19, (b.1) the heat insulating material Ins1 extends so as to surround the side surface of the measuring mechanism Mvf with a distance, and therefore, around the measuring mechanism Mvf. , The space W[fi] connected to the space W[hi] is provided, and (b.2) the outer surface of the casing (on the side of the drive unit Ss[mga]) of the weighing mechanism Mvf is kept at a distance. It is equipped with a heat insulating material Ins2. And (b.3) the heat insulating material Ins2 is at least a part of the casing of the weighing mechanism Mvf and the casing of the drive mechanism Ss[mga] (the casing of the raw material feeder Fdr and/or the casing of the power transmission mechanism Gbx). It is also a heat insulator placed between (at least a part of). The rest of the configuration of the modification 3 is the same as that of the modification 1, and thus the description thereof is omitted.

  According to the modified example 3, since the measuring mechanism Mvf can be thermally insulated from the outside since it has the configurations of the above (b.1) and (b.2), the influence of the ambient temperature is mediated by the measuring mechanism Mvf. It is possible to suppress or prevent the hopper H from reaching the inside. Further, since the drive mechanism Ss[mga] releases the heat received from the outside or the heat generated inside to the measuring mechanism Mvf, the heat insulating material Ins2 is provided by the heat insulating material Ins2 because it has the configuration of (b.3) above. It is possible to cut off the heat, and to suppress or prevent the heat radiation from reaching the hopper H via the measuring mechanism Mvf.

  If the heat insulating material Ins2 alone cannot sufficiently suppress or prevent the heat radiation from the drive mechanism Ss[mga] from reaching the hopper H, the casing of the weighing mechanism Mvf and the casing of the drive mechanism Ss[mga] can be used. It is desirable to install the heat insulating material Ins[sf] between at least a portion (at least a portion of the casing of the raw material feeder Fdr and/or the casing of the power transmission mechanism Gbx) (see FIG. 20). In addition, the heat insulating material Ins2 and the housing of the drive mechanism Ss[mga] are separated from each other, thereby providing a space W[fi]*, and the influence of heat radiation from the drive mechanism Ss[mga] is reduced by the measuring mechanism Mvf. It may be difficult to reach the hopper H through (see FIG. 21). If the effect of this gap is sufficient, it is not necessary to additionally provide the heat insulating material Ins[st] to the heat insulating material Ins2. However, when the effect of this gap is not sufficient, the heat insulating material Ins2 and the heat insulating material Ins[st] are separated from each other, and the space W[2i] is thereby provided to dissipate heat from the drive mechanism Ss[mga]. May be less likely to be exerted on the hopper H via the weighing mechanism Mvf (see FIG. 22).

  Since the rotating shaft Axf is arranged between the drive mechanism Ss[mga] and the measuring mechanism Mvf, the heat received from the outside by the drive mechanism Ss[mga] or the heat generated inside the drive mechanism Ss[mga] passes through the rotary shaft Axf. Then, it may be transmitted to the measuring mechanism Mvf and further into the hopper H, and may affect the temperature Th. However, in the modified example 3, a space W[fi] connected to the space W[hi] is secured around the weighing mechanism Mvf (see FIGS. 19C and 19D), and the space W[ by the temperature control device CL1 is used. Since the effect of adjusting the temperature of [hi] is exerted on the space W[fi], even if such heat is transferred to the measuring mechanism Mvf via the rotation axis Axf, the influence on the temperature Th can be reduced.

  The heat insulating material Ins2 is installed in a place that does not interfere with the operation of the drive mechanism Ss[mga]. The heat insulating material Ins2 may be a heat insulating material different from the heat insulating material Ins1 (see FIGS. 19C and 19D), or may be a heat insulating material integrated with the heat insulating material Ins1. As shown in FIG. 21, a space W[fi]* is provided between the bottom of the weighing mechanism Mvf and the heat insulating material Ins2 so that it is connected to the space W[hi] and the space W[fi]. The temperature control device CL1 may adjust the temperature of the space W[hi] to the space W[fi]*.

  The installation of the heat insulating material Ins[sf] is premised on that there is sufficient space between the heat insulating material 2 and the housing of the drive mechanism to install the heat insulating material Ins[sf]. The heat insulating material Ins[sf] may be integral with or separate from the heat insulating material Ins2. As shown in FIG. 22, when the space W[2i] is provided between the heat insulating material Ins[sf] and the heat insulating material Ins2, the space W[2i] is divided into the space W[hi] and the space W[hi]. It is configured so that it is connected to [fi] (and space W[fi]* in some cases) so that the effect of adjusting the temperature of space W[hi] by temperature control device CL1 extends to space W[2i]. You can

(A-4) Modification 4
23: is explanatory drawing of the modification 4 of the temperature setting mechanism with which the hopper part S[hp] is equipped, FIG. 23(a) is its front view, FIG. 23(b) is its side view. .. As shown in FIG. 23, the modification 4 includes a temperature adjusting device CL1* that adjusts the temperature Th in the hopper H. The rest of the configuration of the modified example 4 is the same as that of the modified example 3, and thus the description thereof is omitted. The description of the derivative form 1 (see FIG. 20), the derivative form 2 (see FIG. 21), and the derivative form 3 (see FIG. 22) of the modified example 3 also applies to the modified example 4 as it is. The temperature control device CL1* is the same as that of the second modification, so its explanation is omitted.

  In the third modification, the temperature Th in the hopper H is controlled or set only by the temperature adjustment device CL1. On the other hand, in the modified example 4, the temperature Th is controlled or set by the two temperature control devices CL1 and CL*. Therefore, according to the modification 4, the temperature Th can be controlled or set more effectively than the modification 3. Therefore, in order to reduce the influence of the environmental temperature on the temperature Th, it is appropriate to adopt the modified example 4 rather than the modified example 3.

  On the other hand, the modified example 4 does not include a heat insulating material that blocks heat transfer between the outer surface of the raw material supply passage Cms and the outside, like the modified examples 1 to 3. In such a case, the heat received from the outside by the raw material supply path Cms is transmitted to the adjacent measuring mechanism Mvf, is transmitted to the inside of the hopper H via the measuring mechanism Mvf, and may affect the temperature Th. .. Therefore, when the influence cannot be ignored, it is appropriate to adopt the modified example 5.

(A-5) Modification 5
24: is explanatory drawing of the modification 5 of the temperature setting mechanism with which the hopper part S[hp] is equipped, FIG. 24(a) is its front view, FIG. 24(b) is its side view. .. As shown in FIG. 24, the modified example 5 includes a heat insulating material Ins2* that covers the outer surface of the raw material supply passage Cms without a distance. The thermal insulation Ins2* may be a thermal insulation that surrounds it at a distance.

  According to the modified example 5, the heat transfer between the outer surface of the raw material supply passage Cms and the outside can be interrupted, so that the heat received from the outside by the raw material supply passage Cms is measured via the raw material supply passage Cms. A phenomenon that is transmitted to the mechanism Mvf from the measuring mechanism Mvf into the hopper H and affects the temperature Th can be suppressed or prevented.

  The configuration of the modified example 5 is the same as that of the modified example 4 except for the heat insulating material Ins2*, and thus the description thereof is omitted. The configuration of the modified example 4 is the same as that of the modified example 3 except for the temperature adjusting device CL1*, and the modified example 3 has the configuration (c.1) in which the heat insulating material Ins1 extends so as to surround the side surface of the measuring mechanism Mvf. Therefore, a space W[fi] connected to the space W[hi] is provided around the weighing mechanism Mvf (see (b.1) above), (c..2) of the weighing mechanism Mvf. Ins2 that covers the outer surface of the casing (on the side of the drive unit Ss[mga]) without any distance (see (b.2) above), (c.3) of the measuring mechanism Mvf In addition to the heat insulating material Ins2, between the housing and at least a part of the housing of the drive mechanism Ss[mga] (at least a part of the housing of the raw material feeder Fdr and/or the housing of the power transmission mechanism Gbx). It is the same as that of the modified example 1 except that the heat insulating material Ins[sf] may be provided (see (b.3) above). The description of the derivative form 1 (see FIG. 20), the derivative form 2 (see FIG. 21), and the derivative form 3 (see FIG. 22) of the modification example 3 also applies to the modification example 5 as it is.

  Note that, in each of FIGS. 25 to 30 and FIGS. 32 to 37, the temperature setting mechanism included in the hopper S[hp] is the modified example 5. This is not intended to limit the invention. The temperature setting mechanism provided in the hopper unit S[hp] is not limited to the modified example 5, and for example, any one of the temperature setting mechanism of the hopper unit shown in FIG. 16 and modified examples 1 to 4 thereof. Which has an improved attachment structure of the heat insulating material (see 3.5 described below) and one of the improvement examples 1 to 3 (see 3.6 described below). May be.

2. A. 3) Relationship with Step S12 In Example-A, the hopper section S[hp] is the region R[s12] in which the step S12 is executed. This is common to the other examples mentioned below.

(Example-B)
25: is explanatory drawing of Example-B of the water treatment apparatus D which concerns on this invention. The configuration and operation of the example-B are basically the same as those of the example-A shown in FIG. 16 except that the temperature setting mechanism of the hopper section S[hp] is the modified example 5. .. The point that the hopper section S[hp] becomes the area R[s12] in which the step S12 is executed is also the same as in the embodiment-A.

(Example-C)
2. C. 1) Features of Configuration FIG. 26 is an explanatory diagram of Example-C of the water treatment device D according to the present invention. The configuration and operation of the example-C are basically the same as those of the example-B shown in FIG. 25, except that the water supply unit S[ws] includes a temperature setting mechanism.

2. C. 2) Temperature setting mechanism included in the water supply unit S[ws] The temperature setting mechanism included in the water supply unit S[ws] is at least (i) a heat transfer tube attached to the outer surface of the water supply conduit Cws and the inside of the heat transfer tube. The temperature control device CL2 that allows the heat medium (h1, h1*) to flow therethrough, and (ii) the heat insulating material Ins3 that covers the outer surface of the water supply conduit Cws and the heat transfer tube.

  h1* is a heat medium before heat exchange with fresh water ws via the tube material of the heat transfer tube and the water supply conduit Cws, and h1 is a heat medium after the heat exchange. There are various substances that can be used as the heat medium (h1, h1*), but it is essential that the substance does not interfere with the function required for the temperature setting mechanism. Typical examples of the heat medium (h1, h1*) are paraffin and CFC substitute.

  Since the outer surface of the water supply conduit Cws is covered with the heat insulating material Ins3, the influence of the environmental temperature on the temperature Tws of the fresh water ws can be reduced. Further, the temperature of the fresh water ws can be set within a specific temperature range by appropriately setting or controlling the temperature of the heat medium h1*.

  The temperature controller CL2 may include a coil heater, and when it is necessary to raise the temperature of the fresh water ws, the temperature of the fresh water ws may be raised by the coil heater via the water supply conduit Cws. Good.

2. C. 3) Relationship with Each Process In the embodiment-C, the water supply unit S[ws] including the temperature setting mechanism is the region R[s22] in which the process S22 is executed.

  When the temperature Tws of the fresh water ws is set within a specific temperature range by the temperature setting mechanism provided in the water supply unit S[ws] and the fresh water ws is charged into the mixing stirring tank Ts, it is stored in the mixing stirring tank Ts. The mixture Cs and the chlorine-based germicide As may be affected by the fresh water ws, and the temperature Tcs of the mixture Cs and/or the temperature Tas of the chlorine-based germicide As may fall within a specific temperature range. In such a case, even when the solution manufacturing unit S[pr] does not have a temperature setting mechanism as in Examples-D to F described later, the solution manufacturing unit S[pr] is It becomes the region R[s23] in which the process is performed and/or the region R[s24] in which the process S24 is performed.

(Example-D)
2. D. 1) Features of Configuration FIG. 27 is an explanatory diagram of Example-D of the water treatment device D according to the present invention. The configuration and operation of Example-D are basically the same as those of Example-C shown in FIG. 26, except that the solution manufacturing unit S[pr] is provided with a temperature setting mechanism.

2. D. 2) Temperature setting mechanism provided in the solution manufacturing unit S[pr] The temperature setting mechanism provided in the solution manufacturing unit S[pr] is at least (i) the distance between the outer surfaces of the mixing and stirring tank Ts and the upper lid Ts1 thereof. Between the heat insulating material Ins4 and the heat insulating material Ins4u, and (ii) the space between the outer surface of the mixing and stirring tank Ts and the heat insulating material Ins4 and the outer surface of the upper lid Ts1 and the heat insulating material Ins4u connected to this space. The space W[ti] is provided with a water supply conduit Cws wound around the outer surface of the body of the mixing and stirring tank Ts. The water supply conduit Cws wound around the outer surface of the body of the mixing and stirring tank Ts functions as a heat transfer tube using the fresh water ws flowing in the water supply conduit Cws as a heat medium. The fresh water ws set or controlled to a certain temperature Tws0 by the temperature setting mechanism provided in the water supply unit S[ws] moves the pipe material and the mixing material of the water supply conduit Cws in the process of moving around the body of the mixing stirring tank Ts through the water supply conduit Cws. Heat is exchanged with the mixture Cs and/or the chlorine-based bactericide As contained in the mixing agitation tank Ts through the components of the agitation tank Ts, and the mixed agitation tank Ts is loaded with fresh water ws* after the heat exchange. It is put in and used as a solvent for the raw solid matter ms*.

  According to the temperature setting mechanism provided in the solution manufacturing unit S[pr], first, the mixing stirring tank Ts and the upper lid Ts1 thereof are surrounded by the heat insulating material Ins4 and the heat insulating material Ins4u, respectively, and the space W[ti] is provided. Since the temperature of W[ti] is adjusted to the level of the temperature of fresh water ws by the water supply conduit Cws, the temperature of the mixture Cs contained in the mixing stirring tank Ts and the temperature Tas of the chlorine-based germicide As are the environmental temperature. The influence of can be reduced. In addition, the temperature Tws0 of the fresh water ws is properly adjusted by the temperature setting mechanism provided in the water supply unit S[ws] (more specifically, the temperature in the solution manufacturing unit S[pr] is within a specific temperature range). By setting or controlling the temperature Tws1 of the fresh water ws* after heat exchange to be within the specific temperature range, the temperature Tcs of the mixture Cs and the temperature Tas of the chlorine-based germicide As stored in the mixing stirring tank Ts can also be set. , Can be set within a specific temperature range.

  The water supply conduit Cws shown in FIG. 27 is wound around the outer surface of the body of the mixing and stirring tank Ts from the top to the bottom, and finally to the top. However, it may be wrapped from bottom to top.

  The temperature setting mechanism provided in the solution manufacturing unit S[pr] is installed between the floor surface of the place where the water treatment device D is installed and the bottom portion of the mixing and stirring tank Ts. It may be provided with a heat insulating material Ins4d for preventing exposure. In that case, if the space W[ti]b between the heat insulating material Ins4d and the bottom of the mixing stirring tank Ts is connected to the space W[ti], the temperature provided in the solution manufacturing unit S[pr] is The effect of adjusting the temperature of the space W[ti] by the setting mechanism can be exerted on the space W[ti]b.

2. D. 3) Relationship with Each Process In Example-D, the water supply unit S[ws] including the temperature setting mechanism is the region R[s22] in which the process S22 is executed. The solution manufacturing unit S[pr] including the temperature setting mechanism is the region R[s23] in which the process S23 is executed and the region R[s24] in which the process S24 is executed.

(Example-E)
2. E. 1) Features of Configuration FIG. 28 is an explanatory diagram of Example-E of the water treatment device D according to the present invention. The configuration and operation of Example-E are basically the same as those of Example-D shown in FIG. 27, except that the temperature setting mechanism of the solution manufacturing unit S[pr] is different.

2. E. 2) Temperature setting mechanism included in the solution manufacturing unit S[pr] The temperature setting mechanism included in the solution manufacturing unit S[pr] of Example-E adjusts the temperature of the space W[ti] by the temperature adjusting device CL3. The temperature adjustment device CL3 is a device that adjusts the temperature of the space W[ti] by circulating the heat medium (h2, h2*) in the space W[ti].

  h2 is supplied from the outside into the space W[it] in the upper part of the mixing and stirring tank Ts, and the contents (mixture Cs and chlorine system) contained in the mixing and stirring tank Ts through the wall surface of the mixing and stirring tank Ts. It is a heat medium that exchanges heat with the germicide As). h2 is also a heat medium that exchanges heat with the air in the mixing and stirring tank Ts above the contents via the upper lid Ts1. h2* is the heat medium h2 after heat exchange, which is discharged to the outside from the space W[it] at the bottom of the mixing and stirring tank Ts or the space W[ti]b at the bottom.

  The heat medium (h2, h2*) shown in FIG. 28 is external→space W[it] above mixing stirring tank Ts→space W[it] below mixing stirring tank Ts or space W[bottom] The flow is from ti]b to the outside, but the flow may be in the opposite direction. In any case, the heat medium (h2, h2*) contributes to the adjustment of the temperature of the entire contents of the mixing and stirring tank Ts approximately above and below.

  There are various substances that can be used as the heat medium (h2, h2*), but needless to say, it is essential that the substance does not inhibit the function required for the temperature setting mechanism of the solution manufacturing unit S[pr]. A typical example of the heat medium (h2, h2*) is air. The air sent out from the air conditioner for performing the air conditioning of the installation location of the hopper H (that is, the air that is blown) may be used as the heat medium (h2, h2*).

  According to the temperature setting mechanism provided in the solution manufacturing unit S[pr], it is not necessary to use fresh water ws as the heat medium. For example, when the environmental temperature is considerably higher than the upper temperature limit in the container, the temperature Tcs and the temperature Tas cannot be kept within the specific temperature range unless the temperature of the fresh water ws is lowered. The load increases. On the other hand, if the temperature of the space W[ti] is adjusted by the heat medium (h2, h2*) using the temperature adjustment device CL3, the load on the temperature adjustment device CL2 can be reduced.

2. E. 3) Relationship with Each Process In the embodiment-E, as in the case of the embodiment-D, the solution manufacturing unit S[pr] including the temperature setting mechanism is the region R[s23] in which the process S23 is executed. This is also the region R[s24] in which the step S24 is executed.

(Example-F)
2. F. 1) Features of Configuration FIG. 29 is an explanatory diagram of Example-F of the water treatment device D according to the present invention. The configuration and operation of the example-F are basically the same as those of the example-E except that a temperature setting mechanism for the connection space described later is provided.

2. F. 2) Temperature setting mechanism for connection space (1) Connection space As shown in FIG. 29, the sterilizing agent piping path Ls has an outer surface other than the pump Ps and the area in the vicinity thereof (hereinafter referred to as “Ps vicinity range”). It is surrounded by insulation material Ins5 at a distance. Therefore, the space between the outer surface of the disinfectant pipe path Ls and the heat insulating material Ins5 is a space on the upstream side (hereinafter, referred to as “upstream space W[bp]1”) and a space on the downstream side (hereinafter referred to as “upstream space W[bp]1”) due to the Ps vicinity range. Hereinafter, it will be divided into "downstream space W[bp]2"). However, the upstream space and the downstream space are connected by the bypass pipe Ct that bypasses the Ps vicinity range.

  In addition, the upstream space W[bp]1 is connected to the space W[ti]b between the outer surface of the bottom of the mixing and stirring tank Ts and the heat insulating material Ins4d. Since the space W[ti]b is connected to the space W[ti], the upstream space W[bp]1 is connected to the space W[ti].

  Therefore, the space W[ti], the space W[ti]b, the upstream space W[bp]1, the bypass pipe Ct, and the downstream space W[bp]2 are, as a whole, a connected space (hereinafter referred to as "connection"). Space)). The outer surface of the bypass pipe Ct may be covered with a heat insulating material (not shown).

(2) Temperature control device CL4
Example-F is equipped with the temperature control device CL4 for circulating the heat medium (h3, h3*) in the connection space. h3 is supplied from the outside into the space W[it] above the mixing and stirring tank Ts, and is stored in the mixing and stirring tank Ts and the sterilizing agent piping path Ls via the wall surface of the mixing and stirring tank Ts. It is a heat medium that exchanges heat with the materials (mixture Cs and chlorine-based bactericide As). h3 is also a heat medium that exchanges heat with the air above the contents in the mixing and stirring tank Ts via the upper lid Ts1. h3* flows from the bottom or bottom of the mixing and stirring tank Ts to the upstream space W[bp]1→the bypass pipe Ct→the downstream space W[bp]2, and then from the downstream space W[bp]2. It is the heat medium h3 after heat exchange, which is discharged to the outside.

  The heat medium (h32, h3*) shown in FIG. 29 is external → space W[it] at the top of the mixing and stirring tank Ts → space W[it] at the bottom of the mixing and stirring tank Ts or space W[ at the bottom. ti]b→upstream side space W[bp]1→bypass pipe Ct→downstream side space W[bp]2, that is, from the upstream side to the downstream side of the connection space, but in the opposite direction. May be. In any case, the heat medium (h3, h3*) contributes to the adjustment of the temperature of almost the entire contents of the mixing and stirring tank Ts and the sterilizing agent piping path Ls. A representative example of the heat medium (h3, h3*) is air, and may be air sent out from an air conditioner for performing air conditioning of the installation location of the hopper H (that is, air sent in).

  According to the temperature control device CL4, by appropriately setting or controlling the temperature of the heat medium h3 (more specifically, so that the temperature in the connection space is within the specific temperature range), the mixture Cs in the connection space is At least one of the temperature Tcs and the temperature Tas of the chlorine-based germicide As and the temperature Tas* of the chlorine-based germicide As in the germicide pipe path Ls can be set within a specific temperature range.

(3) Temperature Setting Mechanism The temperature setting mechanism for the connection space includes at least (i) heat insulating materials Ins4u, Ins4, Ins4d and Ins5 that define the inside and the outside of the connection space, and (ii) the temperature control device CL4. The connection space includes the space W[ti], and the temperature adjusting device CL4 is also a device for adjusting the temperature in the space W[ti]. Therefore, the temperature setting mechanism for the connection space is the solution manufacturing unit S[pr]. It functions as a temperature setting mechanism. In addition, since the connection space includes the upstream space W[bp]1 and the downstream space W[bp]2, and the temperature control device CL4 is also a device that controls the temperature in these spaces, the germicide injection part It also functions as a temperature setting mechanism included in S[is]. In general, the temperature setting mechanism for the connection space serves both as the temperature setting mechanism provided in the sterilizing agent injecting unit S[is] and the temperature setting mechanism provided in the solution manufacturing unit S[pr].

  According to the temperature setting mechanism for the connection space, since the connection space is surrounded by the heat insulating material Ins4u, Ins4, Ins4d and Ins5, in addition, the space W[ti], W[] between the mixing stirring tank Ts and the sterilizing agent piping path Ls. Since bp]1 and W[bp]2 are provided, the temperature Tcs of the mixture Cs in the mixing and stirring tank Ts, the temperature Tas of the chlorine-based germicide, and the temperature of the chlorine-based germicide As in the germicide pipe line Ls. The influence of environmental temperature on Tas* can be reduced. Further, if the temperature of the heat medium h3 is appropriately set or controlled (more specifically, the temperature in the connection space is within a specific temperature range), the mixture Cs contained in the mixing stirring tank Ts is The temperatures Tcs and Tas of the chlorine-based germicide As and the chlorine-based germicide As can be set within a specific temperature range. If necessary, the temperature Tas* of the chlorine-based germicide As in the germicide pipe line Ls can also be set. , Can be set within a specific temperature range.

2. F. 3) Relationship with each process The solution manufacturing unit S[pr] corresponds to a region R[s23] in which the process S23 is performed and a region R[s24] in which the process S24 is performed. The step S32 is executed in the range where the upstream space W[bp]1 and the downstream space W[bp]2 are present in the disinfectant injection part S[is], more specifically, in the disinfectant injection part S[is]. It is the region R[s32].

(Example-G)
FIG. 30 is an explanatory diagram of Example-G of the water treatment apparatus according to the present invention. The description is based on the substance derived from the raw material solid matter ms remaining in the main body of the water treatment apparatus D (hereinafter, “residue”). Say) Re-processing for Re.

  A typical example of the residue Re is the mixture Cs remaining in the mixing stirring tank Ts that is not used in the production of the chlorine-based germicide As and the water Wo is not injected into the mixing stirring tank Ts and the germicide pipe path Ls. It is a chlorine-based bactericide As that remains in the. If these are left unattended, the solvent (fresh water ws) evaporates from the residue Re, and as a result, the raw material solid ms or its composition precipitates, (i) becomes a source of chlorine gas, and (ii) precipitate grows. As a result, problems such as inhibition of mass transfer occur. Evaporation of the solvent (fresh water ws) from the residue Re occurs more or less as long as the water treatment device is mounted on the ship VSL, and even when the temperature Th is set below the upper temperature limit in the container, Even if at least one of the temperature Tws, the temperature Tcs, the temperature Tas, and the temperature Tas* is set within the specific temperature range, if the set temperature is higher (for example, 25 degrees Celsius or more), or The lower the humidity in the place where the water treatment device D is set, the more likely it is to occur, and the longer the voyage time of the ship VSL, the greater the cumulative amount of evaporation, and therefore a countermeasure for the problem becomes necessary. Example-G is provided with a mechanism for performing the post-treatment of the residue Re, thereby suppressing or preventing the occurrence of the problem.

  Hereinafter, with reference to FIG. 30, the post-treatment of the residue Re performed in Example-G, that is, (i) volume reduction/removal of the residue and (ii) prevention of drying of the inner surface will be described. The main body of the water treatment device D illustrated in FIG. 30 corresponds to the example-B, but this is merely an example. The main body of the water treatment device D in the embodiment-G may correspond to embodiments other than the embodiment-B.

2. G. 1) Volume reduction/removal of residue (process G1)
First, the residue storage tank Tsr is prepared in advance. The residue storage tank Tsr includes a pipe Lsr for supplying the residue Re to the residue storage tank Tsr, a pipe Lpt for discharging the content from the residue storage tank Tsr, and a residue storage An exhaust device (not shown) is provided with a pipe Cv* for exhausting the gas accumulated in the tank Tsr for use above. The pipe Lsr is connected to the position Qs on the downstream side of the valve Vs on the disinfectant pipe passage Ls at the position Qsr. The pipe Lpt is provided with a valve Va and a pump Ppt between the position Qpt and the position Qdr.

  The residue storage tank Tsr may be equipped with a device for injecting a low concentration neutralizing agent An#. The injection of a low concentration of the neutralizing agent An# serves to detoxify (i) the free available chlorine existing in the residue Re or generated from the residue, and (ii) the free available chlorine and the medium. It helps to keep the amount of heat generated during the reaction with the Japanese medicine An* low.

  When the residue storage tank Tsr is equipped with a device for injecting a low concentration neutralizing agent An#, it may be equipped with a known stirring means such as an impeller.

(Process G2)
Next, the residue Re existing in any place in the sterilizing agent piping path Ls up to the position Qs connected to the mixing stirring tank Ts, the state in which the valve Vbp is opened and the valves Va and Vs are closed. Then, it is urged by the pump Ps to move along the route of Qs→Lsr→Tsr and accommodated in the residue storage tank Tsr. In that case, fresh water ws may be additionally supplied from the water supply unit S[ws] to the mixing and stirring tank Ts, and the residue Re existing in any of the locations may be diluted with fresh water ws or washed or washed away (however, Since there is an upper limit to the capacity of the residue storage tank Tsr, the contents of the residue storage tank Tsr are moved to another location as necessary, and then fresh water ws is additionally supplied). It should be noted that it is desirable to move the residue Re to the residue storage tank Tsr, for example, after the completion of the third step S3, particularly as soon as possible after the completion of the third step S3 (for example, within one hour). ..

(Process G3)
Next, the residue Re stored in the residue storage tank Tsr is stored in the residue storage tank Tsr by performing one of the processes 1 to 3 described below. .. Then, the process 5 is performed on the residue Re stored in the residue storage tank Tsr. If the situation permits, process 4 is performed before process 5.

(Process 1)
The residue Re is stored in the residue storage tank Tsr for a predetermined period with the valves Va and Vs kept closed. Here, the predetermined period means a period until the next process is started after the residue Re is stored in the residue storage tank Tsr, and depending on the type and content of the next process, ( i) It may be a fairly short period such as a few seconds or a few minutes, or (ii) a period of a medium length such as a few tens of minutes or a few hours, etc. (Iii) It may be a period until a relatively long time, such as several days or weeks, elapses.

(Processing 2)
The residue Re stored in the residue storage tank Tsr by the execution of the process G2 is urged by the pump Ppt with the valves Va and Vs opened, and the route of Tsr→Lpt→Qdr→Ldr1→Ts. And is refluxed into the mixing and stirring tank Ts. Then, the residue Re refluxed in the mixing and stirring tank Ts is moved along the route of Ts→Dbp→Ls→Qs→Lsr→Tsr. At that time, the residue Re is urged by the pump Ps with the valve Vbp open and the valve Vs closed. As a result, the residue Re is discharged from the mixing and stirring tank Ts, stored again in the residue storage tank Tsr, and is generally circulated between the inside of the residue storage tank Tsr and the mixing and stirring tank Ts.

  After performing the above circulation at least once, finally, the residue Re is stored in the residue storage tank Tsr, the valves Va and Vs are closed, and the residue Re is stored in the residue storage tank Tsr for a predetermined period. To do. Here, the predetermined period is synonymous with the predetermined period in the process 1. Generally, the greater the number of times of circulation described above, the higher the effect of reducing or removing the volume of the residue Re from the mixing and stirring tank Ts and the sterilizing agent piping path Ls.

  When the residue Re that has been refluxed in the mixing and stirring tank Ts is stored again in the residue storage tank Tsr, (a) fresh water ws is added to the mixing and stirring tank Ts from the water supply section S[ws]. The residue Re which is supplied and exists in any place in the sterilizing agent piping path Ls up to the position Qs connected to the mixing and stirring tank Ts may be diluted with fresh water ws or washed or washed away. As a result, it is possible to more effectively reduce or remove the residue Re existing in any of the places (however, since the capacity of the residue storage tank Tsr has an upper limit, if necessary, After moving the contents of the residue storage tank Tsr to another location, fresh water ws is additionally supplied).

  In that case, (b) even if a low-concentration neutralizing agent An* is injected from a position Qn in the middle of the water supply conduit Cws and supplied into the mixing stirring tank Ts diluted with fresh water ws. Good. Supplying a low concentration of neutralizing agent An* helps to detoxify (i) free available chlorine existing in the residue Re or generated from the residue, or the neutralizing agent An* and the free In the process of reaction with available chlorine, precipitation, deposition or solidification in any place in the mixing stirring tank Ts and in the sterilizing agent piping path Ls promotes dissolution or peeling of the residue Re, and in any such place. It serves to further enhance the effect of reducing or removing the existing Re, and (ii) to suppress the amount of heat generated during the reaction between the free available chlorine and the neutralizing agent An* to be low.

(Process 3)
The residue Re is urged by the pumps Ppt and Ps with the valve Va opened and the valves Vbp and Vs closed, and Tsr → Lpt → Qdr → Ldr2 → Qs2 → Ls → Qs → Qsr → Lsr → Tsr Move along the path. The position Qs2 is a position on the germicide pipe path Ls, downstream of the valve Vbp and upstream of the pump Ps. As a result, the residue Re is discharged to the outside of the residue storage tank Tsr and is stored again in the residue storage tank Tsr via the sterilizing agent piping path Ls. In general, the residue Re is stored in the residue storage tank Tsr. It is circulated between the tank Tsr for mixing and the mixing and stirring tank Ts.

  After performing the above circulation at least once, finally, the residue Re is stored in the residue storage tank Tsr, the valves Va and Vs are closed, and the residue Re is stored in the residue storage tank Tsr for a predetermined period. To do. Here, the predetermined period is synonymous with the predetermined period in the process 1. In general, the greater the number of times of circulation described above, the higher the effect of reducing or removing the residue Re from the sterilizing agent piping path Ls becomes, and therefore it is desirable to circulate at least twice.

(Processing 4)
When the residue storage tank Tsr is equipped with a device for injecting a low concentration neutralizing agent An# into the tank Tsr and a stirring means for stirring the tank Tsr, the residue storage tank Tsr The residue Re is detoxified by stirring while injecting a low-concentration neutralizing agent An# into the residue Re.

(Process 5)
The residue Re stored in the residue storage tank Tsr is urged by the pump Ppt with the valve Va opened, and moved along the route Ldr3 of Tsr → Lpt → Qdr → Vb3, Discharge to the outside of the residue storage tank Tsr. The discharge destination of the detoxified residue Re may be (i) a ballast tank BT mounted on the ship VSL, (ii) a bilge tank (not shown), or (iii) outside the ship VSL. Good.

  When discharged to the outside of the ballast tank BT mounted on the ship VSL or the ship VSL, it is rendered harmless when the water Wo flows through the ballast water intake pipe Lf toward the ballast tank BT or outside the ship. The residual Re may be moved along the path of Tsr→Lpt→Qdr→Vb3→Vs→Is and injected into the water Wo from the germicide injection port Is via the valve Vs in the open state. In that case, care is taken to prevent the detoxified residue Re from flowing from the position Qs to the pump Ps side (for example, a check valve is provided in advance on the downstream side of the pump Ps).

  Further, when the detoxified residue Re is discharged to the outside of the ship VSL, when the reducing agent supply device N described later is operating, the reducing agent supply path Ln is upstream of the reducing agent injection port In, and is pumped. The detoxified residue Re may be injected from a position downstream of Pn.

  When the residue Re is stored in the residue storage tank Tsr, the treatment 1 and the treatment 5 may be performed. After the treatment 1, the treatment 4 is performed if circumstances permit, and the treatment 5 is finally performed. You may do it. Further, at least two of the processes 2 to 4 may be combined. For example, (i) after performing the process 2 or the process 3, or after performing one of the process 2 and the process 3 first and then the other, the process 4 is performed if the situation permits, and finally the process 5 It is also possible to adopt a combination of (ii) performing (ii) one of processing 2 and processing 3 first and then repeating the other, performing processing 4 if circumstances permit, and finally performing processing 5. ..

2. G. 2) Drying prevention of inner surface When the residue Re is moved to the residue storage tank Tsm in order to prevent the inner surfaces of the mixing stirring tank Ts and the disinfectant pipe line Ls from being dried by the evaporation of the solvent (fresh water ws). Regardless of whether or not, fresh water ws is supplied from the water supply unit S[ws] into the mixing and stirring tank Ts, the mixing and stirring tank Ts is filled with the fresh water ws, and if necessary, additional water is supplied to perform mixing and stirring. Maintain the liquid level of the contents of the tank Ts. In that case, the valve Vbp is opened if necessary. When the valve Vbp is opened, the inside of the disinfectant piping path Ls connected to the lower part of the mixing and stirring tank Ts can be filled with fresh water ws, and the inner surface of the disinfectant piping path Ls can be prevented from drying. ..

  A representative example of a liquid level adjusting mechanism for maintaining the liquid level of the contents of the mixing and stirring tank Ts by supplying and stopping the supply of fresh water ws to the mixing and stirring tank Ts is to change the liquid level of the contents of the mixing and stirring tank Ts. A combination of a liquid level meter to measure and a valve body that is attached to the water supply conduit Cws and automatically opens and closes according to the difference between the liquid level measured by the liquid level meter and the preset liquid level upper limit value. is there. According to such a liquid level adjusting mechanism, the contents of the mixing and stirring tank Ts will be filled up to the liquid level upper limit value, so that the mixing stirring tank Ts and the sterilizing agent piping path Ls that are below the liquid level upper limit value are It is possible to prevent the surface from drying.

  The liquid level adjusting mechanism may be a ball tap type constant water level valve. A ball tap type constant water level valve is attached to the discharge port of the water supply conduit Cws or in the vicinity thereof, and the balls constituting the constant water level valve are floated on the contents of the mixing stirring tank Ts. The constant water level valve is closed in association with the rise of the ball and is opened in association with the fall of the ball, so that the liquid level of the content is maintained at a constant level. Then, it is possible to prevent the inner surfaces of the mixing and stirring tank Ts and the disinfectant pipe path Ls, which are below the certain level, from being dried.

  When the chlorine-based germicide As is produced in the mixing and stirring tank Ts, if the uppermost position of the liquid level of the mixture Cs or the chlorine-based germicide As that comes into contact with the inner surface of the mixing and stirring tank Ts is Lm, water supply The liquid level Lp of the fresh water ws supplied from the section S[ws] into the mixing stirring tank Ts is preferably the same as Lm or higher than Lm. This is because, in such a relationship between Lm and Lp, the inner surface of the mixing stirring tank Ts that was in contact with the mixture Cs or the chlorine-based sterilizing agent As will always be submerged and will not be dried.

<Embodiment 2>
1) Basic configuration FIG. 31 is an explanatory diagram of a basic configuration of a water treatment device D2 that is a modified example of the water treatment device D1 before applying the present invention. Like the water treatment device D1 shown in FIG. 10, this water treatment device D2 is mixed with a solution production section S[pr] for producing a chlorine-based bactericide As by mixing raw solid matter ms and fresh water ws.

The hopper section S[hp] is positioned by a support mechanism (not shown).

1.1) Dissolution Manufacturing Department S[pr]
(1) The solution production unit S[pr] mixes the raw material solid ms with fresh water ws (that is, produces the mixture Cs of the raw material solid ms and fresh water ws) and the mixing unit S[mx]. It is composed of a dissolution promoting unit S[st] that dissolves the raw material solid matter ms in fresh water ws by stirring (that is, produces the chlorine-based germicide As from the mixture Cs).

  (2) The mixing section S[mx] has a buffer tank Tcs and a raw material supply path Cms for supplying the raw material solids ms (or ms*) supplied from the hopper section S[hp] into the buffer tank Tcs. From the discharge opening, the discharge opening of the water supply conduit Cws for supplying the fresh water ws supplied from the water supply section S[ws] into the mixing and stirring tank Ts, and the space above the mixture Cs from the mixing and stirring tank Ts An exhaust means for discharging the gas Gv to the tank and an upper lid Tcs1 for preventing the inside of the mixing and stirring tank Ts from being exposed are provided. The evacuation means is basically the same as the disposal means provided in the water treatment device D1, and therefore its explanation is omitted.

  The lower part of the buffer tank Tcs has a substantially funnel shape, and when the contents (mainly the mixture Cs) contained in the buffer tank Tcs descends, the discharge port Dcbp at the lowermost part of the substantially funnel shape causes a discharge port. It is configured to move toward a loading position Qc1 described later through a pipe Lc0 having one end connected to Dcbp.

  (3) The dissolution promoting unit S[st] includes a closing position Qc1 to which the other end of the pipe Lc0 whose one end is connected to the discharge port Dcbp is connected, a pump Pc located downstream of the supplying position Qc1, and a downstream side of the pump Pc. In addition to connecting the solid-liquid separation device Sp and the input position Qc1, the pump Pc and the solid-liquid separation device Sp in order, a circulation pipe path Lc that connects the solid-liquid separation device Sp and the input position Qc1 is provided. ..

  The content of the buffer tank Tcs, which is charged from the mixing section S[mx] to the charging position Qc1 through the pipe Lc0, is urged and agitated by the pump Pc, and is supplied to the solid-liquid separation device Sp along the circulation pipe path Lc. Move towards. In the process of the transfer, at least a part of the content becomes a solution (a chlorine-based germicide As that is formed by dissolving the raw material solid matter ms in fresh water ws), and the mixture Cs and the chlorine-based germicide As are mixed. In the solid-liquid separation device Sp, (A) a part of the chlorine-based bactericide As, (B) the rest of the chlorine-based bactericide As or fresh water ws, and raw material solids not dissolved in fresh water ws separated into a mixture with ms. The former (A) moves from the liquid outlet Qc2 of the solid-liquid separator Sp to the sterilizing agent injection section S[is] described below, and the remaining latter (B) moves from the solid outlet Qc3 to the circulation piping path Lc. Along this, it moves toward the closing position Qc1. Since the latter (B) is agitated in the process of moving toward the charging position Qc1, at least a part thereof becomes the chlorine-based bactericide As, and at the charging position Qc1, the former to the bactericide injection section S[is] (A) The amount of the contents of the buffer tank Tcs that is sufficient to replenish the moving amount is received, and the contents of the replenished buffer tank Tcs are urged again by the pump Pc, stirred, and the circulation pipe It moves toward the solid-liquid separation device Sp along the path Lc.

  Since the dissolution promoting unit S[st] is configured as described above, the chlorine-based germicide As is continuously supplied in the process in which the content of the buffer tank Tcs that has been added or replenished circulates along the circulation piping route Lc. The chlorine-based bactericide As produced can be separated by the solid-liquid separator Sp.

  A typical example of the solid-liquid separation device Sp is a liquid cyclone. When the solid-liquid separator Sp is a hydrocyclone, the liquid level of the contents of the liquid cyclone is arranged below the liquid level of the contents of the buffer tank Tcs. The movement of the contents of the buffer tank Tcs from the mixing section S[mx] to the charging position Qc1 is due to the action of gravity and the negative pressure of the pump Pc.

That is, h4 is supplied from the outside into the space W[it] above the buffer tank Tcs, and through the wall surface of the buffer tank Tcs, the contents (mainly the mixture Cs) contained in the buffer tank Tcs are supplied. It is a heat medium that exchanges heat. h4 is also a heat medium that exchanges heat with the air in the buffer tank Tcs above the contents through the top lid Tcs1. h4* is the heat medium h4 after heat exchange, which is discharged to the outside from the space W[it] below the buffer tank Tcs. The heat medium (h4, h4*) shown in FIG. 34 flows in the order of external→space W[it] above the buffer tank Tcs→space W[it] below or below the buffer tank Tcs→outside. However, the flow may be in the opposite direction. In any case, the heat medium (h4, h4*) contributes to the adjustment of the temperature of the entire contents of the buffer tank Tcs approximately above and below. A typical example of the heat medium (h4, h4*) is air.

(Example-L)
36: is explanatory drawing of Example-L of the water treatment apparatus which concerns on this invention, The description is related with the post-treatment with respect to the residue Re which remains in the main body of the water treatment apparatus D. FIG. The configuration and operation of Example-L are basically the same as those of Example-G of Embodiment 1 shown in FIG. 30, except that the water treatment device D is the water treatment device D of Embodiment 2. Is the same.

  Hereinafter, with reference to FIG. 36, the post-treatment of the residue Re performed in Example-L, that is, (i) volume reduction/removal of the residue and (ii) prevention of drying of the inner surface will be described. The main body of the water treatment device D depicted in FIG. 36 corresponds to Example-H, but this is merely an example. The main body of the water treatment device D in the embodiment-H may correspond to embodiments other than the embodiment-H.

2. L. 1) Volume reduction/removal of residue (process L1)
First, the residue storage tank Tsr is prepared in advance. The residue storage tank Tsr includes a pipe Lsr for supplying the residue Re to the residue storage tank Tsr, a pipe Lpt for discharging the content from the residue storage tank Tsr, and a residue storage An exhaust device (not shown) is provided with a pipe Cv* for exhausting the gas accumulated in the tank Tsr for use above. The pipe Lsr is connected to the position Qs on the downstream side of the valve Vs on the disinfectant pipe passage Ls at the position Qsr. The pipe Lpt is provided with a valve Va and a pump Ppt between the position Qpt and the position Qdr.

  Note that, as in the case of Example-G, the residue storage tank Tsr may be equipped with a device for injecting a low concentration neutralizing agent An#. In the case of being equipped with a device for performing the above, a known stirring means such as an impeller may be provided.

(Process L2)
Next, in the buffer tank Tcs, in the pipe Lc0, the circulation pipe path Lc and the residue Re existing in any place in the germicide pipe path Ls connecting between the solid-liquid separator Sp and the position Qs, With the valves Va and Vs closed, they are urged by the pumps Pc and Ps to move along the path of Qs→Lsr→Tsr and accommodated in the residue storage tank Tsr. In that case, fresh water ws may be additionally supplied from the water supply unit S[ws] to the buffer tank Tcs, and the residue Re existing at any of the locations may be diluted with fresh water ws or washed or washed away (however, Since there is an upper limit to the capacity of the material storage tank Tsr, the contents of the residue storage tank Tsr are moved to another location as necessary, and then fresh water ws is additionally supplied). It should be noted that it is desirable to move the residue Re to the residue storage tank Tsr, for example, after the completion of the third step S3, particularly as soon as possible after the completion of the third step S3 (for example, within one hour). ..

(Process L3)
Next, the residue Re stored in the residue storage tank Tsr is stored in the residue storage tank Tsr by performing one of the processes 1 to 3 described below. .. Then, the process 5 is performed on the residue Re stored in the residue storage tank Tsr. If the situation permits, process 4 is performed before process 5.

(Process 1)
The residue Re is stored in the residue storage tank Tsr for a predetermined period with the valves Va and Vs kept closed. Here, the predetermined period means a period until the next process is started after the residue Re is stored in the residue storage tank Tsr, and depending on the type and content of the next process, ( i) It may be a fairly short period such as a few seconds or a few minutes, or (ii) a period of a medium length such as a few tens of minutes or a few hours, etc. (Iii) It may be a period until a relatively long time, such as several days or weeks, elapses.

The residue Re contained in the residue storage tank Tsr due to the execution of the process H2 is urged by the pump Ppt with the valves Va and Vs opened, and the route of Tsr→Lpt→Qdr→Ldr1→Tcs. Along with, and reflux into the buffer tank Tcs. After that, the residue Re refluxed in the buffer tank Ts is moved along the path of Tcs→Dcbp→Lc0→Qc1→Lc→Sp→Qc2→Ls→Qs→Lsr→Tsr. At that time, the residue Re is urged by the pump Ps with the valve Vbp opened and the valve Vs closed, and the circulation piping path Lc is circulated once or plural times as necessary. As a result, the residue Re is discharged from the buffer tank Tcs, stored again in the residue storage tank Tsr, and is generally circulated between the residue storage tank Tsr and the buffer tank Tcs.

  After performing the above circulation at least once, finally, the residue Re is stored in the residue storage tank Tsr, the valves Va and Vs are closed, and the residue Re is stored in the residue storage tank Tsr for a predetermined period. To do. Here, the predetermined period is synonymous with the predetermined period in the process 1. In general, as the number of times of circulation described above increases, the effect of reducing or removing the residue Re from the buffer tank Tcs, the pipe Lc0, the circulation pipe passage Lc, and the germicide supply passage Ls from the position Qc2 to the position Qs becomes higher. Therefore, it is desirable to circulate it twice or more.

  When the residue Re that has been refluxed in the buffer tank Tcs is to be stored in the residue storage tank Tsr again, (a) fresh water ws is additionally supplied to the buffer tank Tcs from the water supply section S[ws]. , Thereby, the residue Re existing in the buffer tank Tcs, in the pipe Lc0, in the circulation pipe line Lc and in the germicide supply route Ls from the position Qc2 to the position Qs may be diluted with fresh water ws or washed or washed away. .. Thereby, the volume or removal of the residue Re can be performed more effectively (however, since the capacity of the residue storage tank Tsr has an upper limit, the residue storage tank Tsr can be added as necessary. After moving the contents of to another location, additional supply of fresh water ws).

  At that time, (b) a low concentration neutralizing agent An* may be injected from a position Qn in the middle of the water supply conduit Cws and supplied into the buffer tank Tcs in a state diluted with fresh water ws. .. Supplying a low concentration of neutralizing agent An* helps to detoxify (i) free available chlorine existing in the residue Re or generated from the residue, or the neutralizing agent An* and the free In the process of the reaction with available chlorine, in the buffer tank Tcs, in the pipe Lc0, in the circulation pipe route Lc and in the residue Re existing in any place in the germicide supply route Ls from the position Qc2 to the position Qs. It promotes the dissolution and exfoliation of the residue Re that has been deposited, deposited or solidified at any place, and enhances the effect of reducing or removing the volume of the residue Re that exists at any place, and (ii) the release It helps to reduce the amount of heat generated during the reaction between available chlorine and the neutralizing agent An*.

(Process 3)
The residue Re is energized by the pumps Ppt and Ps with the valves Va opened and the valves Vbp and Vs closed, and Tsr → Lpt → Qdr → Ldr2 → Qs2 → Lc → Sp → Qc2 → Ls → Qs → Move along the route of Lsr→Tsr. The position Qs2 is a position on the germicide pipe path Ls, downstream of the valve Vbp and upstream of the pump Ps. As a result, the residue Re is discharged to the outside of the residue storage tank Tsr, and stored again in the residue storage tank Tsr via the circulation piping path Lc and the sterilizing agent piping path Ls, and the residue Re is generally The residue storage tank Tsr is circulated between the mixing and stirring tank Ts.

  After performing the above circulation at least once, finally, the residue Re is stored in the residue storage tank Tsr, the valves Va and Vs are closed, and the residue Re is stored in the residue storage tank Tsr for a predetermined period. To do. Here, the predetermined period is synonymous with the predetermined period in the process 1. In general, the greater the number of times of circulation described above, the higher the effect of reducing or removing the residue Re from the circulation piping path Lc and the sterilizing agent piping path Ls becomes, and therefore it is desirable to circulate at least twice.

  The position Qs2 may be on the pipe Lc0. In that case, it is also possible to reduce or remove the residual Re existing in the pipe Lc0 that connects the position Qs2 and the position Qc1. The greater the number of times of the above circulation, the higher the effect of reducing or removing the residual Re.

(Processing 4)
When the residue storage tank Tsr is equipped with a device for injecting a low concentration neutralizing agent An# into the tank Tsr and a stirring means for stirring the tank Tsr, the residue storage tank Tsr The residue Re is detoxified by stirring while injecting a low-concentration neutralizing agent An# into the residue Re.

(Process 5)
The residue Re stored in the residue storage tank Tsr is urged by the pump Ppt with the valve Va open and moved along the path Ldr3 of Qpt → Qdr → Vb3 to remove the residue. Discharge to the outside of the storage tank Tsr. The discharge destination of the detoxified residue Re may be (i) a ballast tank BT mounted on the ship VSL, (ii) a bilge tank (not shown), or (iii) outside the ship VSL. Good.

  When discharged to the outside of the ballast tank BT mounted on the ship VSL or the ship VSL, it is rendered harmless when the water Wo flows through the ballast water intake pipe Lf toward the ballast tank BT or outside the ship. The residual residue Re may be moved along the path of Tsr→Lpt→Qdr→Ldr3→Vb3→Vs→Is and injected into the water Wo from the germicide inlet Is via the valve Vs in the open state. .. In that case, care is taken to prevent the detoxified residue Re from flowing from the position Qs to the pump Ps side (for example, a check valve is provided in advance on the downstream side of the pump Ps).

  Further, when the detoxified residue Re is discharged to the outside of the ship VSL, when the reducing agent supply device N described later is operating, the reducing agent supply path Ln is upstream of the reducing agent injection port In, and is pumped. The detoxified residue Re may be injected from a position downstream of Pn.

  When the residue Re is stored in the residue storage tank Tsr, the treatment 1 and the treatment 5 may be performed. After the treatment 1, the treatment 4 is performed if circumstances permit, and the treatment 5 is finally performed. You may do it. Further, at least two of the processes 2 to 4 may be combined. For example, (i) after performing the process 2 or the process 3, or after performing one of the process 2 and the process 3 first and then the other, the process 4 is performed if the situation permits, and finally the process 5 It is also possible to adopt a combination of (ii) performing (ii) one of processing 2 and processing 3 first and then repeating the other, performing processing 4 if circumstances permit, and finally performing processing 5. ..

2. L. 2) Prevention of drying of inner surface Residue Re remains in order to prevent the inner surface of the buffer tank Tcs, the pipe Lc0 and the circulation piping path Lc, especially the inner surface of the buffer tank Tcs, from drying due to evaporation of the solvent (fresh water ws). Regardless of whether it is moved to the object storage tank Tsr, fresh water ws is supplied from the water supply unit S[ws] into the buffer tank Tcs, and the fresh water ws fills the buffer tank Tcs and is added if necessary. To maintain the liquid level of the contents of the buffer tank Tcs. When the liquid level of the fresh water in the buffer tank Tcs is maintained, the fresh water ws has entered the pipe Lc0 and the circulation pipe route Lc. Can be prevented together with.

  A representative example of the liquid level adjusting mechanism for maintaining the liquid level of the content of the mixing and stirring tank Ts by supplying and stopping the fresh water ws to the mixing and stirring tank Ts is the case of Example-G of the first embodiment. Same as described. Further, this liquid level adjusting mechanism may be a ball tap type constant water level valve as in the case of the embodiment-G.

  When the uppermost liquid level of the content (mainly the mixture Cs) that comes into contact with the inner surface of the buffer tank Tcs when the buffer tank Tcs contains the mixture Cs is Lm, from the water supply unit S[ws] The liquid level Lp of the fresh water ws supplied into the buffer tank Tcs is preferably the same as Lm or higher than Lm. This is because, in such a relationship between Lm and Lp, the inner surface of the mixing stirring tank Ts that was in contact with the mixture Cs or the chlorine-based sterilizing agent As will always be submerged and will not be dried.

<Addendum>
1) About Embodiment 1 1.1) Countermeasures against Heat Dissipated from Drive Motor Mti The drive motor Mti depicted in FIGS. 16 and 25 to 30 is the same as the drive motor Mti shown in FIG. Similarly, the casing is in direct contact with the outer surface of the upper lid Ts1. In such a case, the heat emitted from the drive motor Mti may be transmitted through the upper lid Ts1, the raw material supply passage Cms, and the measuring mechanism Mvf, and may be transmitted into the hopper H to raise the temperature Th. Further, the heat raises the temperature of the air above the mixing stirring tank Ts, and is transmitted to the contents (mixture Cs and chlorine-based bactericide As) via the air or through the side wall of the mixing stirring tank Ts, and the temperature Tcs And the temperature Tas may rise, and the temperature Th may rise indirectly.

  Therefore, when installing the drive motor Mti, a heat insulating material is interposed between the case of the drive motor Mti and the outer surface of the upper lid Ts1, (ii) the case of the drive motor Mti has low thermal conductivity. Using a support mechanism made of a material, fix the upper lid Ts1 at a position spaced apart from the outer surface of the upper lid. (iii) In the case of (ii) on the left side, at the outer surface of the upper lid Ts1 and a position spaced above it. A heat insulating material is provided between the fixed drive motor Mti and the housing to prevent heat emitted from the drive motor Mti from being transferred to the upper lid Ts1 as much as possible.

2) Addendum on Embodiment 2 2.1) Further Removal of Residue in Example-L In the case of Example-L, the residue Re is taken out from the position Qs on the disinfectant piping path Ls to remove the residue. Since it is moved to the storage tank Tsr, the residue Re that could not be moved from the solid-liquid separation device Sp to the sterilizing agent piping path Ls side is part of the circulation piping path Lc (for example, shown in FIG. 36). There is a case where the residual remains in the circulating piping route Lc) from the position Qc3 to the position Qc1. Therefore, the residue Re is taken out from the position Qsa (see FIG. 36) on the circulation pipe route Lc and moved to the residue storage tank Tsr. With this, a larger amount of the residue Re can be moved to the residue storage tank Tsr.

  A specific example of the procedure for taking out the residue Re from the position Qsa and moving it to the residue storage tank Tsr is as follows.

  First, the branch pipe Lsra of the circulation pipe path Lc that connects between the position Qsa and the residue storage tank Tsr is prepared. The branch pipe Lsar is capable of changing whether or not the residue Re can be moved from the position Qsa to the residue storage tank Tsr by opening/closing the valve Vsar provided therein.

(Specific example 1)
The residue Re urged by the pumps Pc and Ps is taken out from the position Qs on the disinfectant piping path Ls and moved to the residue storage tank Tsr, while being urged by the pump Pc and circulated. A part of the residue Re circulating in the pipe path Lc is moved from the position Qsa to the residue storage tank Tsr through the branch pipe Lsar with the valve Vsar kept open. This reduces the amount of the residue Re that can remain in a part of the circulation piping path Lc.

(Specific example 2)
The valve Vsar is closed and the residue Re is prevented from moving from the circulation piping Lc to the branch piping Lsar, and then the residue Re urged by the pumps Pc and Ps is transferred to the disinfectant piping path Ls. The process of taking out from the position Qs and moving to the residue storage tank Tsr is executed. After the execution of the process is completed, the pump Ps is stopped, and the valve (not shown) included in the disinfectant piping path Ls is closed to prevent the residue Re from flowing from the position Qc2 to the disinfectant piping path Ls. After that, the valve Vsar is opened, and the residue Re urged by the pump Pc and circulating in the circulation pipe path Lc is moved from the position Qsa to the residue storage tank Tsr through the branch pipe Lsar. .. This reduces the amount of the residue Re that can remain in a part of the circulation piping path Lc.

3) Addendum common to the first and second embodiments 3.1) Insulation material To the hopper H, the mixing stirring tank Ts, the buffer tank Tcs, the circulation piping path Lc, the sterilizing agent piping path Ls, etc. by the worker who performs maintenance and inspection For convenience of access, any of the insulation materials (Ins1, Ins1*, Ins2, Ins2*, Ins3, Ins4, Ins4u, Ins4d, Ins5, Ins6*, Ins7, etc.) are configured so that at least some of them can be removed. ing.

3.2) Measures against excessive supply of fresh water ws G. If the liquid level adjusting mechanism mentioned in 2) fails, the contents may overflow from the mixing and stirring tank Ts, and the working environment of the installation location of the water treatment device D may be deteriorated. Therefore, in case of a failure of the liquid level adjusting mechanism, an overflow pipe is attached to the mixing stirring tank Ts, and when the liquid level of the contents of the mixing stirring tank Ts and the buffer tack Tcs exceeds the upper limit, the upper limit is set. The content in excess is discharged to the outside of the mixing and stirring tank Ts through the overflow pipe.

  The above 2. H. The same applies to the liquid level adjusting mechanism referred to in 2). If it fails, the contents overflow from the buffer tank Tcs, which may deteriorate the working environment of the installation location of the water treatment device D. Therefore, in case of a failure of the liquid level adjustment mechanism, an overflow pipe is attached to the buffer tank Tcs, and when the liquid level of the contents of the buffer tank Tcs exceeds the upper limit, the contents exceeding the upper limit are Are discharged to the outside of the buffer tank Tcs through the overflow pipe.

3.3) Thermal insulation design of dissolution manufacturing unit S[pr] FIG. 37 is an explanatory diagram of Example-M of the water treatment device according to the present invention. Example-M is a water treatment device D installed on the pedestal Bp arranged on the floor Bv at the installation location ER in the ship VSL, and like Example-H to Example-L, i) Hopper section S[hp], water supply section S[ws], dissolution production section S[pr] including mixing section S[mx] and dissolution promoting section S[st], and bactericide injection section S[ is].

  Unlike Example-H to Example-L, in Example-M, the mixing section S[mx] and the dissolution promoting section S[st] share a temperature setting mechanism. Specifically, (i) The entire melting production section S[pr], and therefore both the mixing section S[mx] and the dissolution promoting section S[st] are installed in a single heat insulating space W[u], and (ii) the heat insulating space W[ The temperature adjusting device CL(u) is provided for adjusting or setting the temperature in [u] to set or control the temperature Tcs and the temperature Tas within a specific temperature range. The temperature setting mechanism provided in the hopper unit S[hp] is not limited to the modification 5 shown in FIG. The temperature control device CL(u) is a known device having at least a cold heat generating function, and is preferably a known device having both a cold heat generating function and a warm heat generating function.

  In the case of Example-M, since both the mixing section S[mx] and the dissolution promoting section S[st] are installed in the heat insulating space W[u], the temperature in the heat insulating space W[u] is adjusted. By doing so, it is possible to simultaneously set the temperature Tcs of the mixture Cs mainly in the mixing portion S[mx] and the temperature Tas of the chlorine-based bactericide As in the dissolution promoting portion S[st].

  The melting manufacturing section S[pr] in the first embodiment can be installed in the heat insulating space W[u] illustrated in FIG. 37. In that case, a through hole may be provided in the heat insulating material Ins7 above the heat insulating space W[u] so that the rotating shaft Axi can be inserted, and the drive motor Mti can be installed above the heat insulating material Ins7 above. A representative example of the water treatment device D configured in this manner is Example-E.

3.4) Air conditioner At the installation location ER of the water treatment device D, it is preferable to install an air conditioner. The air conditioner CL(ac) shown in FIG. 37 adjusts the temperature and humidity of the air h(a) in the installation location ER through heat exchange with the outside of the installation location ER, and after temperature control or humidity control. By sending the subsequent air h(a)* into the installation location ER, it has the function of adjusting not only the environmental temperature but also the humidity.

  By using the air conditioner CL(ac), the temperature setting mechanism of each of the hopper section S[hp], solution manufacturing section S[pr], water supply section S[ws], etc. Roles can be complemented and reduced. Also, when chlorine gas generated upon self-decomposition of the raw material solid ms contains water, it exhibits strong corrosiveness and causes problems such as irritating odor, where an air conditioner CL(ac) is used. For example, since it is possible to dehumidify the installation location ER, it is possible to suppress or prevent the occurrence of those problems.

  The installation of the air conditioner CL(ac) is not limited to the case of the embodiment-M. It can be installed in any of Examples-A to L.

3.5) Mounting structure of heat insulating material in hopper part (1) FIG. 38 is an explanatory view of a mounting structure of heat insulating material to the hopper part S[hp], and FIG. 38(a) is a front view thereof. 38(b) is a side view thereof.

  The mounting structure of the heat insulating material to the hopper S[hp] shown in FIG. 38 is to enclose the hopper H with a heat insulating panel. More specifically, (i) a support mechanism for the hopper S[hp]. A pair of support pillars Fr fixed to at least one of the high rigidity part (not shown) and the high rigidity part constituting the housing of the water treatment device D (see also FIG. 37), (ii ) A pair of auxiliary support columns Fr* arranged in parallel with the pair of support columns Fr with a distance therebetween, and (iii) four corners on the lower end sides of the pair of support columns Fr and the pair of auxiliary support columns Fr*. There are a total of four lower horizontal frame members Xd which are located at the respective sides of the quadrangle and fix the four corners, and (iv) the upper ends of the pair of support columns Fr and the pair of auxiliary support columns Fr* are four corners. At the position of each side of the quadrangle, fixing the four corners, a total of four upper horizontal frame members Xu, and (v) one end fixed to the pair of support columns Fr, and the pair of auxiliary support columns Fr* The other end is fixed to the lower horizontal frame member Xd that fixes the lower end portions of the lower horizontal frame member Xd, and thereby the stiffening member Bm that fixes the vertical position of the lower horizontal frame, and (vi) the supporting pillar Fr and adjacent to it. Direct or auxiliary to the rectangular frame composed of the auxiliary support column Fr* and the upper horizontal frame member Xu and the lower horizontal frame member Xd that fix the support column Fr and the corresponding support column Fr* at the upper and lower parts. Side insulation panels IP(1), IP(1)* attached via members (not shown), and (vii) the pair of support pillars Fr and the upper and lower parts between the pair of support pillars Fr. Side heat insulation panel IP(2) attached directly or via an auxiliary member (not shown) to a rectangular frame constituted by the upper horizontal frame member Xu and the lower horizontal frame member Xd fixed by (viii) Directly or auxiliary to a square frame composed of the pair of auxiliary support pillars Fr* and an upper horizontal frame member Xu and a lower horizontal frame member Xd that fix the space between the pair of auxiliary support pillars Fr* at the upper and lower portions. A side insulation panel IP(2)* attached via a member (not shown) and (ix) a total of four upper horizontal frame members Xu directly or in an auxiliary member (not shown) in a rectangular frame. Upper insulation panel IP(u), which is attached via (x), and (x) a total of four lower horizontal frame members Xd, each of which is directly or through an auxiliary member (not shown) to a rectangular frame. Can be installed It has a lower surface insulation panel and (xi) an uppermost insulation panel IP(t) which is detachably installed on the upper surface insulation panel IP(u). The supporting pillar Fr, the auxiliary supporting pillar Fr*, the upper horizontal frame member Xu, the lower horizontal frame member Xd, the panel plate, etc. surrounding the hopper H are covered with a heat insulating material (not shown), and their members. The boundary portion between them is sealed by a seal wrap and then covered with a heat insulating material (not shown), which prevents exposure to the outside.

  The heat insulation panels IP(1), IP(1)*, IP(2), IP(2)*, IP(u), IP(d) and IP(t) are all mounted on the panel P. Ins1 is used for the side insulation panels IP(1), IP(1)*, IP(2), IP(2)* and the top insulation panel IP(u). The heat insulating material of the lower heat insulating panel IP(d) is the heat insulating material Ins2, and the heat insulating material of the uppermost heat insulating panel IP(t) is the heat insulating material Ins1*.

  The upper heat insulating panel IP(u) is divided into two parts before mounting, as shown in FIG. This is to facilitate installation. Therefore, the top cross-section panel IP(u) may be an undivided unitary piece if it is not difficult to mount.

  The upper surface insulation panel IP(u) has an opening at a position corresponding to the lid for facilitating the operator's access to the lid attached to the end opening of the raw material supply port Crf provided in the hopper H. When mounting the uppermost heat insulating panel IP(t) on the upper heat insulating panel IP(u), the heat insulating material Ins1* attached to the panel board P is inserted into the opening of the upper cross sectional panel. When removing the uppermost heat insulating panel IP(t) from the upper heat insulating panel IP(u), the heat insulating material Ins1* is pulled out from the opening.

  The use of the uppermost heat insulating panel IP(t) is not essential for inserting the heat insulating material Ins1* into or removing from the opening of the top cross-sectional panel. The heat insulating material itself not attached to the panel board P may be used as the heat insulating material Ins1* to fill the opening or be taken out from the opening.

  Since the lower surface heat insulation panel IP(d) is installed between the bottom of the casing of the weighing mechanism Mvf and at least a part of the casing of the drive unit Ss[mga], it passes through the rotation axis Axf and the raw material supply passage Cms. It has an opening. The lower heat insulating panel IP(d) is divided into two parts before installation as shown in FIG. 38 to facilitate installation.

  The attachment structure of the heat insulating material shown in FIG. 38 can be applied to the hopper portion S[hp] of any of the embodiments. For example, in the case of the modified example 5 shown in FIG. 24, the side heat insulation panels IP(1), IP(1)* have holes for passing conduits for passing the heat medium of the temperature control devices CL1, CL1*. It is provided, but its depiction is omitted.

  The support pillar Fr, the auxiliary support pillar Fr*, the upper horizontal frame member Xu and the lower horizontal frame member Xd shown in FIG. 38 have the hopper H as a ridge and the polyhedron surrounding the hopper H is a rectangular parallelepiped. However, the polyhedron is not limited to a rectangular parallelepiped or a hexahedron as long as the hopper H can be surrounded by a heat insulating material.

  (2) The heat insulating material mounting structure shown in FIG. 38 can be manufactured, for example, by the following procedure.

  [1] A pair of support pillars Fr are provided on at least one of a highly rigid part of the support mechanism (not shown) of the hopper S (hp) and a highly rigid part of the housing of the water treatment device D. To fix. At that time, if necessary, a distance between the pair of support columns Fr is maintained and a reinforcing member Za for reinforcing them is attached.

  [2] Attach the stiffening member Bm to the pair of support columns Fr.

  [3] While supporting a part of the lower horizontal frame member Xd by the stiffening member Bm, while supporting the pair of supporting columns Fr, the pair of auxiliary supporting columns Fr*, the upper horizontal frame member Xu and the lower horizontal frame member Xd, the hopper H, Assemble to enclose. The order of connecting the pair of support pillars Fr, the pair of auxiliary support pillars Fr*, the upper horizontal frame member Xu and the lower horizontal frame member Xd is not particularly limited, and if necessary for the connection, a tightening tool, You may use connection auxiliary members, such as a fixture and an attachment.

  [4] A side heat insulation panel IP (prepared in advance) directly or through an auxiliary member in a rectangular frame composed of the pair of support columns Fr and the upper horizontal frame member Xu and the lower horizontal frame member Xd facing each other. 2) Install. A side heat insulation panel IP (2) prepared in advance, directly or through an auxiliary member, in a rectangular frame composed of a pair of auxiliary support pillars Fr* and the opposing upper horizontal frame member Xu and lower horizontal frame member Xd. )* is attached. The support pillar Fr, the auxiliary support pillar Fr* adjacent to the support pillar Fr, and the rectangular frame composed of the upper horizontal frame member Xu and the lower horizontal frame member Xd facing each other are prepared directly or through an auxiliary member in advance. Install side insulation panels IP(1), IP(1)*. An upper surface insulation panel IP(u) prepared in advance is attached to a rectangular frame constituted by the upper horizontal frame member Xu directly or via an auxiliary member. The lower surface heat insulation panel IP(d) prepared in advance is attached to a rectangular frame constituted by the lower horizontal frame member Xd directly or through an auxiliary member. After installing the top insulation panel IP(u), install the top insulation panel X(t). There are no particular restrictions on the mounting order of the side insulation panels IP(1), IP(1)*, IP(2), IP(2)*, the top insulation panel IP(u) and the bottom insulation panel IP(d). Absent. If necessary, angle members may be attached to the corners of the rectangular frame to reinforce it.

  [5] The exposed portions of the support columns Fr, the auxiliary support columns Fr*, the upper horizontal frame member Xu, the lower horizontal frame member Xd, the panel plate P, etc. are covered with a heat insulating material (not shown). Further, the boundary portion between these members is sealed with a seal wrap and then covered with a heat insulating material (not shown).

  (3) The structure for mounting the heat insulating material on the hopper S[hp] as described above is easy to construct because it has the structure of mounting the heat insulating panel in the frame. Such a heat insulating material attachment structure facilitates the work of subsequently attaching the heat insulating material to the hopper S[hp] of the water treatment device D already installed in the ship VSL, and is useful. ..

3.6) Improvement Example of Hopper S[hp] When setting or controlling the temperature Th in the hopper H to be equal to or lower than the upper limit of the temperature in the container, it is desirable to keep the humidity in the hopper H lower. This is because if the humidity in the hopper H is low, even if chlorine gas is generated in the hopper H for some reason, metal corrosion is less likely to occur and an irritating odor is less likely to occur. On the other hand, fresh water ws is also supplied from the water supply unit S[ws] to the dissolution production unit S[pr] in which the raw material solids ms (ms*) are charged from the hopper S[hp]. The moisture derived from the fresh water ws rises through the raw material supply path Cms and the measuring mechanism Mvf, reaches the hopper H, and may increase the humidity in the hopper H. Therefore, hereinafter, an improved example of the hopper section S[hp] that prevents or makes it difficult for the moisture derived from the fresh water ws supplied to the dissolution manufacturing section S[pr] to reach the hopper H will be described.

(1) Improvement example 1
The supply amount of the gas A1 per unit time is increased by using the discharge support mechanism shown in FIG. As a result, a flow of the gas A1 flowing into the dissolution production section S[pr] through the raw material supply path Cms is created, and the invasion of water derived from fresh water ws into the hopper section S[hp] is prevented. As described above, the temperature of the gas A1 is such that the environmental temperature is equal to or lower than the upper limit of the temperature inside the container. Alternatively, the humidity of the gas A1 supplied into the measuring mechanism Mvf is set as low as possible. Due to these, there is a danger that the raw material solids ms remaining in the measuring mechanism Mvf or the raw material supply path Cms becomes a source of chlorine gas, or the generated chlorine gas contains water and is highly corrosive, causing an irritating odor. It is possible to reduce the risk that

(2) Improvement example 2
FIG. 39 is an explanatory diagram of a second modification of the hopper section S[hp]. In this improvement example 2, the gas A2 is supplied into the measuring mechanism Mvf from the supply port Din side, moved from the discharge port Dout to the raw material supply passage Cms, and flows into the dissolution manufacturing section S[pr] through the raw material supply passage Cms. By doing so, the invasion of water derived from fresh water ws into the hopper S[hp] is prevented. In the case of the improved example 1, when the supply amount of the gas A2 is increased, a flow that remains in the measuring mechanism Mvf without moving to the raw material supply path Cms from the outlet Dout is formed, and the raw material solids ms remaining in the measuring mechanism Mvf May increase. On the other hand, when the gas A2 is supplied, a gas flow is formed from the supply port Din side to the discharge port Dout side, so that an increase in the amount of the raw material solid matter ms remaining in the measuring mechanism Mvf is suppressed. Or it can be prevented.

  In the improved example 2, further, the gas A3 is supplied to the raw material supply passage Cms and is allowed to flow into the dissolution production section S[pr] through the raw material supply passage Cms, so that the hopper section S[[ hp] is blocked.

  In order to prevent or make it difficult for the moisture derived from the fresh water ws to reach the hopper H, at least one of the gas A2 and the gas A3 may be supplied.

  A typical example of the gas A2 and the gas A3 is dehumidified air. The temperature of each of the gas A2 and the gas A3 is such that the environmental temperature is equal to or lower than the upper limit of the temperature inside the container. Further, desirably, the humidity of the gas A1 supplied into the measuring mechanism Mvf is set as low as possible. As a result, it is possible to reduce the risk that the raw material solid matter ms remaining in the measuring mechanism Mvf or the raw material supply path Cms becomes a source of chlorine gas.

(3) Improvement example 3
(3-1) FIG. 40 is an explanatory diagram of a third modified example of the hopper S[hp], FIG. 40(a) is a front view thereof, and FIG. 40(b) is a side view thereof. In this improvement example 3, a valve Vbl is provided in the middle of the raw material supply path Cms or at the tip on the side of the melting production section S[pr], and the raw material solids ms (from the hopper section S[hp] to the melting production section S[pr] When the charging of ms*) is stopped, the valve Vbl is closed to prevent the moisture derived from the fresh water ws from entering the hopper S[hp]. A typical example of the valve Vbl is a ball valve which is known to have a very high shutoff performance. If the degree of automation of the water treatment device D is increased, it is preferable to use an electric ball valve.

  (3-2) FIGS. 40(c) and 40(d) are a derivative example 1 and a derivative example of the improvement example 3 of the hopper section S[hp] shown in FIGS. 40(a) and 40(b), respectively. It is explanatory drawing of 2, and is a side view in each case. In the derivation example 1 of the improved example 3, the gas A4 is supplied from the side surface of the valve Vbl to the raw material supply passage Cms, and is allowed to flow into the dissolution production section S[pr] through the raw material supply passage Cms, whereby the water content derived from the fresh water ws is obtained. Prevents intrusion into the hopper S [hp] of. In the modified example 2 of the modified example 3, when the valve Vbl is installed at a position separated from the upper lid Ts1 (or Tcs1), the gas A5 is supplied to the raw material supply path Cms between the valve Vbl and the upper lid Ts1 (or Tcs1). By supplying and flowing into the dissolution manufacturing section S[pr] through the raw material supply channel Cms, the invasion of water originating from fresh water ws into the hopper section S[hp] is prevented.

  In order to prevent or make it difficult for the moisture derived from the fresh water ws to reach the hopper H, at least one of the gas A4 and the gas A5 may be supplied. A typical example of the gas A4 and the gas A5 is dehumidified air. The temperature of each of the gas A4 and the gas A5 should be below the upper limit of the temperature inside the container.

  In order to prevent the moisture derived from fresh water ws from entering the hopper S[hp], at least one of the above-mentioned improvement examples 1 to 3 (including the derivative examples 1 and 2 of the improvement example 3) is adopted. However, it is desirable to adopt all at the same time.

<Embodiment 3>
Vessel equipped with ballast water treatment device FIG. 41 is an explanatory diagram of the basic configuration of a vessel VSL equipped with a ballast water treatment device, FIG. 42 is an explanatory diagram of a sterilization process executed in the vessel VSL, and FIG. FIG. 8 is an explanatory diagram of a return process executed in the ship VSL.

1.1) Basic configuration As shown in FIG. 41, the ship VSL includes a water intake or sea chest IT, a ballast pump Pm, a ballast tank BT, and a drain DO, and the sea chest IT and the ballast pump. Pm and ballast tank BT are connected, seawater Wo taken from the outside through the intake IT is circulated toward the ballast tank BT, and chlorine-based germicide As is injected in the middle, and chlorine-based germicide As is injected. The ballast water intake pipe line Lf that discharges the ballast tank BT into the ballast tank BT is connected to the ballast tank BT, the ballast pump Pm, and the outlet DO, and the ballast water Wt taken from the ballast tank BT is connected to the outlet DO. And a filter device F for filtering seawater Wo flowing through the ballast water intake pipe line Lf, and a downstream of the filter device F. The ballast water intake pipe line Lf is provided with a disinfectant supply device D having a disinfectant injection port Is for injecting a chlorine-based disinfectant As.

  The vessel VSL further includes a reducing agent supply device N having a reducing agent inlet In for injecting the reducing agent An into the ballast water drainage piping path Lr, and a ballast tank is provided in the middle of the ballast water drainage piping path Lr. The reducing agent An is injected into the ballast water Wt taken from the BT to reduce the influence of the bactericide As remaining in the ballast water Wt, and the ballast water Wt is changed to the ballast water Wn that is allowed to be discharged outboard. , The ballast water Wn can be discharged to the outside of the ship from the drain port DO. The discharge side of the ballast pump Pm is usually provided with a check valve Vcm for preventing a backflow that may occur in the event of an abnormality such as a pump stop or failure.

  The ballast water intake pipe line Lf is a pipe line of IT → Qa → Pm → Vcm → Qb → F → Qc → Is → Mxc → Qe → BT, which is drawn in bold in FIG. Downstream of Is and upstream of the ballast tank BT, a mixer Mxs for promoting the mixing of the seawater Wo taken from the outside of the ship and the chlorine-based germicide As is provided. The ballast water drainage pipe line Lr is a pipe line of BT → Qa → Pm → Vcm → Qb → Qd → Qc → In → Mxc → Qe → DO, which is drawn in bold in FIG. 43.

  When a part or all of the operation or adjustment of the ballast pump Pm, a plurality of valves (not shown), the disinfectant supply device D, the reducing agent supply device N, etc. is manually performed. Except for the above, it is automatically performed according to a control program pre-installed in the control device PLC or another control device (not shown). For example, setting of opening and closing of a plurality of open/close valves for selecting one of the ballast water intake piping path Lf and the ballast water drainage piping path Lr, and setting of the set piping path to another piping path. The change and the switching of the operation mode of the ballast pump Pm, and the switching of the operation and stop of each of the disinfectant supply device D and the reducing agent supply device N are manually performed by performing a part or all of the setting, changing and switching operations.

And may be a signal for controlling the operation of other devices/apparatuses. When the operation of the equipment/devices is directly controlled based on the output of the measuring device, the operation is not controlled by the control device PLC.

1.2) Sterilization treatment and reduction treatment Among the ballast water treatments, sterilization treatment means sterilization of seawater Wo flowing through the ballast water intake pipe line Lf before the seawater Wo is stored in the ballast tank BT. This is a process of injecting a chlorine-based bactericidal agent As from the agent supply device D from the bactericidal agent injection port Is, and makes it possible to store the seawater Wo as sterilized seawater Ws in the ballast tank BT.

  Among the ballast water treatments, the reduction treatment refers to the supply of a reducing agent to the seawater Wt, which flows through the ballast water drainage piping Lr and is taken out from the ballast tank BT, before the seawater Wt is drained outboard. By injecting the reducing agent An from the device N, the free effective chlorine derived from the chlorine-based bactericidal agent As remaining in the Wt is reduced by injecting the reducing agent An, and the seawater Wt is outboard. This is a treatment that renders wastewater harmless until it reaches a level that allows it. The seawater Wt can be discharged outboard as detoxified seawater Wn by reduction treatment.

  Although sterilization is indispensable for ballast water treatment, reduction treatment is not indispensable. If the amount of free available chlorine derived from the chlorine-based germicide As in seawater Wt is sufficiently low and seawater Wt has already reached the level at which outboard drainage is allowed, it is not necessary to add a reducing agent to seawater Wt. Therefore, it is not necessary to perform the reduction process.

1.3) Ballast Water Treatment Device The ballast water treatment device realizes the basic configuration of the ship VSL shown in FIG. 41 by being mounted on the ship VSL, and is also shown in FIGS. 42 and 43, respectively. Which is a device for performing sterilization treatment and reduction treatment, specifically, a filter device F, a sterilizing agent supply device D, a reducing agent supply device N, a mixer Mxc, and a pipe connecting the position Qb and the filter device F. The pipe path connecting the path and the filter device F to the position Qc is a device that constitutes an element of the ballast water treatment device. The water treatment device according to the present invention is a device for performing a sterilization treatment by injecting a chlorine-based bactericidal agent As into the seawater Wo moving toward the ballast tank BT from the outside of the ship VSL equipped with the ballast tank BT, that is, sterilization. It is nothing but agent supply device D.

1.4) Example When the freighter VSL leaves the first port with an empty cargo, seawater Wo is loaded into the ballast tank BT at the first port, and seawater from the ballast tank BT is loaded at the second port where cargo is loaded. Wt is discharged overboard, then loaded with cargo and returned to the first port. Then, when emptying again from the first port where the cargo was unloaded, when sailing towards the second port, when loading seawater Wo into the ballast tank BT at the first port, first at the first port, Taking seawater Wo into the ship, when circulating the ballast water discharge piping route Lf, the chlorine-based germicide As using the water treatment device according to the present invention as the germicide supply device D from the germicide inlet Is, Inject it into the circulating seawater Wo. Thus, the seawater Wo is sterilized, and the seawater Wo (that is, the seawater Ws) in which the chlorine-based bactericide As is injected is stored in the ballast tank BT. The freighter VSL then departs from the first port, sails and goes to the second port for loading cargo.

  Next, at the second port, when the seawater Wt is discharged from the ballast tank BT to the outside of the ship, the free effective chlorine concentration remaining in the seawater Wt is increased when the seawater Wt is circulated to the ballast water drainage piping route Lr. When the discharge level is higher than the allowable level, the reducing agent supply device N is used to inject the reducing agent An from the reducing agent inlet In into the circulating seawater Wt, thereby reducing the seawater Wt to render it harmless. Drain Wt (that is, seawater Wn) outboard. When the concentration of free available chlorine remaining in the seawater Wt is equal to or lower than the drainage allowable level, the reducing agent supply device N is not used to inject the reducing agent An, and the seawater Wt is drained out of the ship as it is. The freighter VSL then leaves the second port with cargo loaded and sails to the first port for unloading.

  After unloading at the first port, the freighter VSL will be empty. Therefore, when the cargo ship VSL again leaves the first port with an empty cargo, as in the first place, the water treatment device according to the present invention is used as the germicide supply device D to sterilize seawater Wo. The seawater Wo (that is, the seawater Ws) in which the chlorine-based sterilizer As is injected is stored in the ballast tank BT after being treated.

  Execution examples of the sterilization treatment using the water treatment device according to the present invention as the sterilizing agent supply device D are the second and fifth embodiments of the water treatment method according to the present invention shown in FIGS. 6 and 9, respectively. is there.

  During the period Pa shown in FIG. 6 and FIG. 9, after performing the second stage S2 for the sterilization treatment in the first port, the second port, which is the departure destination, returned to the first port. It is almost equal to the period until the second sterilization process is started later in the first port. The same applies to the period Pa*.

  During the period Pb shown in FIG. 6 and FIG. 9, after performing the second stage S3 for the sterilization treatment in the first port, the second port, which is the departure destination, returned to the first port. It is almost equal to the period until the second sterilization process is started later in the first port. The same applies to the period Pb*.

<Principle and effect of the invention>
(1) First, in each of the A-th and M- th embodiments of the present invention, when a chlorine-based bactericide is produced, a solid substance of a chlorinated isocyanuric acid compound which is a raw material thereof (hereinafter, referred to as “raw material solid substance”). A) is mixed with fresh water rather than seawater. This is because seawater contains a larger amount of chlorine components, and thus when the raw solid material is mixed with seawater, a larger amount of chlorine gas may be generated as compared with the case where it is mixed with fresh water.

In addition, according to each of the Ath and Mth aspects of the present invention, the upper limit of the temperature in the hopper or other temporary storage container in which the raw material solids are temporarily stored (hereinafter referred to as "the upper limit of the temperature in the container"). Is set to 39 degrees Celsius, so that the temperature of the raw solid material that is stored in the temporary storage container or remains unused or adheres to the inner surface of the temporary storage container. , The temperature can be kept at 39 degrees Celsius or lower, which is lower than the self-decomposition temperature (about 40 degrees Celsius), and therefore the generation of chlorine gas from the temporary storage container can be suppressed, and the chlorine gas The adverse effect can be reduced.

(2) In a raw material feeder (feeder) for supplying the raw material solids supplied from the hopper, which is a temporary storage container, to the solution manufacturing unit, a raw material feeder is configured to come into contact with the raw material solids. The wall surface of the member that exists is certainly present. For example, when the raw material feeder is equipped with a measuring mechanism for dividing the raw solid material into a small amount or a predetermined amount, the raw solid material may be included in the wall surface of the member constituting the measuring mechanism. There are things that come into strong contact with. In that case, there is a high possibility that raw material solids will remain on the wall surface or its surroundings. When such a residue exceeds about 40 degrees Celsius, it self-decomposes and becomes a source of chlorine gas. On the other hand, according to the Nth aspect of the present invention, since the temperature in the measuring mechanism is set to be equal to or lower than the temperature upper limit in the container, it is possible to suppress the generation of chlorine gas from the measuring mechanism. The adverse effect of chlorine gas can be reduced.

(3) The raw material solids supplied from the hopper to the solution manufacturing unit may come into contact with the surface of the member forming the moving path thereof and adhere to and remain on the surface. When such a residue exceeds about 40 degrees Celsius, it self-decomposes and becomes a source of chlorine gas. In contrast, according to the O mode of the present invention, since the temperature of within the movement path below vessel upper temperature limit, it is possible to suppress the generation of chlorine gas from the mobile path, It is possible to reduce the above-mentioned adverse effects of chlorine gas.

(4) According to the B form of the present invention, when a room temporarily storage vessel is installed, the space elsewhere temperature (hereinafter referred to as "ambient temperature") of less than 39 degrees Celsius, the environment Since it is not necessary to lower the temperature in the temporary storage container to a level below the temperature, energy consumption required for setting or controlling the temperature in the temporary storage container can be saved.

(5) According to the C form of the present invention, not only during being charged temporarily storage for container raw material solids, for even the temporary storage before and / or charged after charging Since the temperature inside the container is set below the upper limit of the temperature inside the container, the temperature of the raw material solids stored or remaining in the temporary storage container is less likely to exceed 40 degrees Celsius, and the temperature of the temporary solids is temporarily below 40 degrees Celsius. Even if the temperature is higher than 40 degrees Celsius, the time when the temperature is higher than 40 degrees Celsius can be shortened, and therefore, the generation of chlorine gas from the temporary storage container can be suppressed more effectively. It is possible to further reduce the above-mentioned adverse effects of chlorine gas.

(6) In each of the D-th and P- th embodiments of the present invention, the temperature of the fresh water before being mixed with the raw material solid is within the range of 5 degrees Celsius or more and 39 degrees Celsius or less (hereinafter, “within a specific temperature range”). It may be said that))).

Thus, according to each of the above modes, (i) an aqueous solution having an effective chlorine concentration necessary as a bactericidal agent for treating ballast water can be obtained, and (ii) self-decomposition of a raw material solid in contact with fresh water is prevented. Since it is possible to easily control the temperature in the container in which the solid raw material is temporarily stored, the effects of the A-th and M- th embodiments of the present invention become more remarkable.

(7) In each form of the E and the Q of the present invention, since mixing the raw materials solids and fresh water within a certain temperature range, the temperature of the mixture even go falls within a specific temperature range. If the temperature of the fresh water of the mixture is not lower than 5 degrees Celsius, if it is lower than that, the solubility of the raw material solid in fresh water is too low to obtain an aqueous solution having an effective chlorine concentration necessary as a bactericide, Or because it takes too long to obtain.

(8) According to the F form of the present invention, since the temperature of the chlorine-based disinfectant which can dissolve the raw material solids fresh water within 39 degrees Celsius, the raw material solids to the chlorine-based disinfectant is not selected Even if it is mixed in as it is dissolved, it is possible to suppress or prevent the generation of chlorine gas triggered by the self-decomposition of the undissolved raw material solid. Further, even if heat is transferred from the chlorine-based bactericide to the mixture of the raw material solids and fresh water, it is possible to prevent the undissolved raw material solids in the mixture from reaching 40°C or higher.

(9) According to the form of the G and the T of the present invention, when the environmental temperature is high, the temperature of the temporary storage for the container can be reliably suppressed below vessel temperature limit. In particular, according to each of the embodiments, it is possible to prevent the temperature in the temporary storage container from rising due to the influence of the increasing environmental temperature and to prevent the temperature in the container from rising.

According to the H and the form of the U (10) the present invention, when the environmental temperature is low, can be increased to ensure that more container temperature lower limit temperature of a temporary storage for the container. In particular, according to each of the embodiments, it is possible to prevent the temperature in the temporary storage container from lowering below the lower limit of the internal temperature of the container due to the influence of the environmental temperature that tends to decrease.

(11) According to the form of the I and the W of the present invention, when the temperature of the chlorine-based disinfectant is high, the temperature of the temporary storage for the container can be reliably suppressed below vessel temperature limit. In particular, according to each of the embodiments, it is possible to prevent the temperature in the temporary storage container from rising due to the influence of the increasing environmental temperature and to prevent the temperature in the container from rising.

(12) The G to I-th and the T of the present invention, according to the form of the U and the W, flexibly setting the reference temperature in accordance with the conditions of the water treatment, the water treatment method and a water treatment device Can be customized.

(13) According to the R form of the present invention, is set within a temperature specified temperature range in the tank, because the temperature of the raw material solid and a mixture of fresh water in the tank is gradually falls within a specific temperature range since, it is possible to obtain the same effect as that exhibited by the respective form of the E and the Q of the present invention.

In contrast, according to the R form of the present invention, the temperature of a chlorine-based germicide present in the tank go falls within a specific temperature range, triggered by the self-decomposition of the raw material solid undissolved Generation of chlorine gas can be prevented or suppressed.

(14) In the S-th embodiment of the present invention, the temperature of the chlorine-based bactericide discharged by the solid-liquid separator or the temperature in the solid-liquid separator is set within a temperature range of 5 degrees Celsius or higher and 39 degrees Celsius or lower. To be set.

Thus, according to the S-th embodiment, it is possible to prevent the self-decomposition of the undissolved raw material solid in the chlorine-based bactericide, and the effects of the A-th and M- th embodiments of the present invention become more remarkable. Become.

It can also be avoided that the heat released from fresh water adversely affects the setting of the temperature in the temporary storage container.

According to the V form of the present invention, the flexibility to set the reference temperature in accordance with the conditions of the water treatment, it is possible to customize the water treatment method and a water treatment device.

In contrast, according to the form of the J and the W of the present invention, not only during the production of a chlorine-based germicide, its production after the end of at least a certain period, and each of the K and the Y of the present invention According to the form, not only during the injection into the water used as the ballast water of the chlorine-based sterilizing agent, for at least a certain period after the end of the injection, the temperature in the temporary storage container is set to 39 degrees Celsius or less, It is also possible to prevent or suppress the generation of chlorine gas which is triggered by the self-decomposition of the raw material solids remaining in the temporary storage container.

In addition, in each of the G and R forms of the present invention, the "certain period" means a raw material that remains unused in the temporary storage container after the production of the chlorine-based bactericide is completed. Period until the amount of chlorine gas generated due to self-decomposition of solid matter decreases to such an extent that the effect of preventing or reducing the adverse effect of chlorine gas generated due to self-decomposition of the raw solid matter can be said to have been exerted Say. For each form of the G and the R of the present invention, a "certain period", after completion of injection into the seawater a chlorine-based germicide, remaining unused in the temporary storage for container Until the amount of chlorine gas generated by the self-decomposition of the raw material solids decreases to the extent that the effect of preventing or reducing the adverse effect of the chlorine gas generated by the self-decomposition of the raw material solids can be said to have been exerted. Refers to the period. In any case, the “certain period” may be a short period or a long period.

"At least a certain period after the end of production of the chlorine-based disinfectant" in each form of the J and the W of the present invention, the end of infusion into seawater "chlorine disinfectant in the form of the K and X of the present invention "At least for a certain period of time" often overlaps, but need not overlap.

For example, the temperature in the temporary storage container is set to 39 degrees Celsius or less continuously from the first execution of the water treatment method according to the A-th embodiment of the present invention to the next execution. May be.

(17) According to the Lth aspect of the present invention, since the solid material of the raw material is supplied to the container, the solid material can be used up, that is, the end of the first stage can be postponed, and the seawater treatment can be continued. ..

(18) According to the Y-th aspect of the present invention, the temperature inside the hopper can be set or controlled using the temperature adjusting device.

According to the Z-th aspect of the present invention, it is rational because the surroundings of the hopper can be cooled or heated together with air conditioning of the installation location of the hopper.

In the AA form of the present invention, since the heat insulating material is attached to the periphery of the hopper, even if the environmental temperature adversely affects or is likely to adversely affect the setting of the temperature in the hopper, eliminate the adverse effect. Or it can be reduced. In this embodiment, the heat insulating material attached to the periphery of the hopper may be in contact with at least a part of the outer surface of the hopper, and may be separated from the outer surface of the hopper without contacting the outer surface of the hopper. You may have.

In the form of the BB of the present invention, since the solution prepared portion is provided in a space surrounded by the heat insulating material, the temperature of the contents of the environmental temperature is discharged from the temperature and the solution preparation of the solution preparation unit Even when the setting is adversely affected or there is a possibility of such an adverse effect, the adverse effect can be eliminated or reduced. In this embodiment, the heat insulating material that surrounds the space where the solution manufacturing unit is installed may be in contact with at least a part of the outer surface of the tank, the pipe, or the like that configures the solution manufacturing unit. It may be separated from the outer surface.

In the CC form of the present invention, during the injection of the chlorine-based bactericide into the ballast water and after the injection or after the injection, the mixture of the raw material solid and fresh water is in contact with the solution production section. It does not dry because at least a part of the surface comes into contact with fresh water supplied from the water supply section. Therefore, according to this aspect, at least a part of the surface, it is possible to suppress or prevent the precipitation, deposition or solidification of the chlorinated isocyanuric acid compound which is a solute and its constituent components, and eventually maintenance inspection. The frequency can be reduced. In addition, since the raw material solid matter may remain in the solution manufacturing unit, the temperature of the fresh water supplied from the water supply unit and/or the temperature in the solution manufacturing unit after the fresh water is supplied are set to 39 degrees Celsius. It is desirable to set or control below.

According to the DD of the present invention, to store the mixture of the raw materials solids and fresh water remaining without being used for the preparation of a chlorine-based germicide or a chlorine-based germicide that remains without being used for disinfection of ballast water Since it has a residue storage tank, it is possible to suppress or prevent the precipitation, deposition or solidification of the chlorinated isocyanuric acid compound or its constituent components that are solutes in the container constituting the water treatment device, the piping path, etc. Therefore, maintenance inspections can be reduced, and the frequency can be reduced.

According to the EEth aspect of the present invention, the flow of the gas supplied from the gas supply device can suppress or prevent the moisture derived from the fresh water supplied to the solution manufacturing unit from reaching the hopper. it can.

According to the FF mode of the present invention blocking, when the raw material solids is not supplied to the solution prepared unit from the hopper, the movement path of the material solids between the hopper and the solution prepared portion by a mechanism such as a valve Therefore, it is possible to suppress or prevent the moisture derived from the fresh water supplied to the solution manufacturing unit from reaching the hopper.

According to the GGth form of the present invention, at least the side surface of the body of the hopper is surrounded by the heat insulating panel, so that the heat insulating structure of the hopper can be relatively easily constructed.

(8) When the heat released from the fresh water ws may hinder the temperature Th of the raw material solid ms in the container H from being set below the upper limit of the internal temperature of the container, for example, a pipe through which fresh water ws circulates in the container H. closely and, if there is a risk that the heat released from the pipe affects the temperature Th, it is desirable to perform the reaction process S22 until the danger is eliminated. In that case, t[s22s] is preferably set to a point before t[s21s].

(3) The start time t[s3s] of the third stage S3 can be said to be the time when the seawater Wo introduced from outside the vessel VSL reaches the inlet of the chlorine-based bactericide As.

4) Example 4.1) Figure 5 to 9, respectively, are explanatory views relating to Examples 1 to 5 of the water treatment method according to the present invention. In all the examples, the reference temperature Tm(h) is 38 degrees Celsius unless otherwise specified.

(Example 3)
Example 3, as shown in Figure 7, also similarly to Example 1, after the end of the Preparation stage S0, is started in the order of the temperature setting step S12 → storage step S11 → step S21 → step S31, the storage The process S11→process S21→temperature setting process S12→process S31 are ended in this order. Further, the end time point t[s11e] of step S11 and the end time point t[s21e] of step S21 are both times after the start time point t[s31s] of step S31.

On the other hand, when the processes S22, S23, S24, and S32 are performed in the first to fourth embodiments, the following settings are made.
(A) In any of the examples, the start time point t[s22s] of step S22 is set to before the start time point t[s21s] of step S21, and preferably t[s22s] is set to a time point before t[s21s]. To do.
(B) In any of the examples, preferably, the start time t[s32s] of step S32 is before the start time t[s31s] of step S31, and more preferably t[s32s] is greater than t[s31s]. The previous time. However, or a chlorine-based germicide As injected into seawater Wo in a chlorine-based germicide As a third step S3, is produced in the second stage S2 is present in the same location, but Oh Ru in different locations, one from the other In some cases, the steps S24 and S32 can be regarded as a single step if the heat conduction to the steps is performed. In such a case, there is little actual benefit of distinguishing the process S24 from the process S32, and t[s32s] can be regarded as the start time t[s24s] of the process S24.
(C) The end times t[s22e], t[s23e], and t[s24e] of steps S22, S23, and S24 are all preferably after the end time t[s21e] of step S21.

<Addendum>
(1) The temperature setting or control in the water treatment method according to the present invention does not have to be constantly executed. For example, setting or control of making the temperature in the temporary storage container equal to or lower than the upper temperature limit in the container does not need to be performed when the temperature in the temporary storage container is equal to or lower than the upper temperature limit in the container. Similarly, it is not necessary to set or control the temperature in the temporary storage container to be equal to or higher than the lower temperature limit in the container when the temperature in the temporary storage container is equal to or higher than the lower temperature limit in the container. Further, in both the fourth and sixteenth embodiments, it is essential to set the temperature of fresh water to 5 degrees Celsius or higher, but when the temperature of fresh water is 5 degrees Celsius or higher, No settings are required. In both the fifth and seventeenth embodiments, it is essential to set the temperature at which the raw material solid is mixed with fresh water to 5 degrees Celsius or higher, but the temperature at which the raw material solid is mixed with fresh water is When the temperature is 5 degrees Celsius or higher, it is not necessary to set it. In the eighteenth aspect, it is essential to set the temperature in the tank of the solution manufacturing unit to 5 degrees Celsius or higher. However, when the temperature in the tank of the solution manufacturing unit is 5 degrees Celsius or higher, No settings are required. The nineteenth form has an essential configuration in which the temperature of the fresh water is set so that the temperature of the chlorine-based bactericide discharged by the solid-liquid separator or the temperature in the solid-liquid separator becomes 5 degrees Celsius or higher. However, when the temperature is 5 degrees Celsius or higher, it is not necessary to set the temperature.

1.1) Solution Manufacturing Department S[pr]
The solution production unit S[pr] mixes the raw material solids ms with the fresh water ws (that is, produces the mixture Cs of the raw material solids ms and the fresh water ws) and the mixture Cs with stirring. The raw material solid matter ms is dissolved in fresh water ws (that is, the chlorine-based bactericide As is produced from the mixture Cs) and a dissolution promoting unit S[st]. However, since the mixing of the raw material solid ms and the fresh water ws and the stirring of the mixture Cs of both are performed in the mixing stirring tank Ts included in the solution manufacturing section S[pr], the mixing section S[mx] and the dissolution promoting section are included. The boundary with S[st] is ambiguous, and it is difficult to clearly distinguish the two.

(2) FIG. 13 is an explanatory diagram of the principle of the measuring mechanism Mvf. The holes (or individual holes) Op provided in the rotary table Rtf form a recess U in the inner wall surface together with the main surface Bt of the pedestal except when it is at the position of the discharge port Dout (see FIG. 13A). At the position of the discharge port Dout, the recess U is not formed to communicate with the discharge port Dout (see FIG. 13B). Therefore, the recess U can accommodate a fixed amount of the raw material solid ms (raw material supply ms*) that has descended from the receiving port Din, and can be moved to the discharge port Dout as the rotary table Rtf rotates. , A fixed amount of the raw material solid matter ms* can be discharged to the discharge port Dout and moved to the raw material supply path Cms (see FIG. 12(b)).

The measuring mechanism Mvf may include a discharge support mechanism that discharges the raw material solid matter ms* from the hole Op of the rotary table Rtf and assists the movement to the discharge port Dout. FIG. 15 is an explanatory diagram of an example of the discharge support mechanism. The discharge support mechanism shown in FIG. 15 causes the gas s to be ejected downward from above the hole Op when the hole Op communicates with the discharge port Dout, and the pressure of the gas A1 at that time causes It is a mechanism for moving from the hole Op to the raw material supply path Cms through the discharge port Dout. A typical example of the gas A1 is dehumidified air. If the ejection range of the gas A1 is widened, fine particles of the raw material solid ms attached to the wall surface of the hole Op or the surface of the rotary table Rtf can also be moved to the raw material supply path Cms. The gas A1 that has moved to the solution manufacturing unit S[pr] through the raw material supply passage Cms is exhausted to the outside by the exhaust means provided in the solution manufacturing unit S[pr].

(4) The drive mechanism Ss[mga] is for generating the rotational driving force of the rotary shaft Axf and the rotary shaft Axf to which the rotary table Rtf is attached directly or via a known power transmission mechanism such as a gear or a belt. The motor Mth and a known power transmission mechanism Gbx such as a gear and a belt for transmitting the driving force from the motor Mth to the rotation shaft Axf. Incidentally, when mounting coaxially to the rotary shaft Axf the rotating shaft of the motor Mth, an instrument Gado force transmission mechanism Gbx used for the mounting. By controlling the operation of the motor Mth, the operation of the rotary table Rtf can also be controlled.

If the heat insulating material Ins2 alone cannot sufficiently suppress or prevent the heat radiation from the drive mechanism Ss[mga] from reaching the hopper H, the casing of the weighing mechanism Mvf and the casing of the drive mechanism Ss[mga] can be used. It is desirable to install the heat insulating material Ins[sf] between at least a portion (at least a portion of the casing of the raw material feeder Fdr and/or the casing of the power transmission mechanism Gbx) (see FIG. 20). Further, by spacing between the heat insulating material Ins2 and a housing of the drive mechanism Ss [mga], thereby the space W [fi] * provided, the drive mechanism Ss [mga] or these effects of heat radiation metering mechanism Mvf It may be difficult to reach through the hopper H (see FIG. 21). If the effect of this gap is sufficient, it is not necessary to additionally provide the heat insulating material Ins[st] to the heat insulating material Ins2. However, when the effect of this gap is not sufficient, the heat insulating material Ins2 and the heat insulating material Ins[st] are separated from each other, and the space W[2i] is thereby provided to dissipate heat from the drive mechanism Ss[mga]. May be less likely to be exerted on the hopper H via the weighing mechanism Mvf (see FIG. 22).

The configuration of the modified example 5 is the same as that of the modified example 4 except for the heat insulating material Ins2*, and thus the description thereof is omitted. The configuration of the modified example 4 is the same as that of the modified example 3 except for the temperature control device CL1*. In the modified example 3, (c.1) the heat insulating material Ins1 extends so as to surround the side surface of the weighing mechanism Mvf. Therefore, a space W[fi] connected to the space W[hi] is provided around the weighing mechanism Mvf (see (b.1) above), (c..2) of the weighing mechanism Mvf. Ins2 that covers the outer surface of the casing (on the side of the drive unit Ss[mga]) without any distance (see (b.2) above), (c.3) of the measuring mechanism Mvf In addition to the heat insulating material Ins2, between the housing and at least a part of the housing of the drive mechanism Ss[mga] (at least a part of the housing of the raw material feeder Fdr and/or the housing of the power transmission mechanism Gbx). It is the same as that of the modified example 1 except that the heat insulating material Ins[sf] may be provided (see (b.3) above). The description of the derivative form 1 (see FIG. 20), the derivative form 2 (see FIG. 21), and the derivative form 3 (see FIG. 22) of the modification example 3 also applies to the modification example 5 as it is.

According to the temperature setting mechanism provided in the solution manufacturing unit S[pr], it is not necessary to use fresh water ws as the heat medium. For example, when the environmental temperature is considerably higher than the container temperature limit, if not lower the temperature of the fresh water ws, since it becomes impossible to keep the temperature Tcs and temperature Tas in a certain temperature range, according to the temperature regulating device CL2 The load increases. On the other hand, if the temperature of the space W[ti] is adjusted by the heat medium (h2, h2*) using the temperature adjustment device CL3, the load on the temperature adjustment device CL2 can be reduced.

1.1) Solution Manufacturing Department S[pr]
(1) The solution production unit S[pr] mixes the raw material solid ms with fresh water ws (that is, produces the mixture Cs of the raw material solid ms and fresh water ws) and the mixing unit S[mx]. It is composed of a dissolution promoting unit S[st] that dissolves the raw material solid matter ms in fresh water ws by stirring (that is, produces the chlorine-based germicide As from the mixture Cs).

2. J. 2) Temperature setting mechanism of mixing section S[mx] The function of the temperature setting mechanism of mixing section S[mx] is to surround at least (i) each of the buffer tank Tcs, its upper lid Tcs1 and its bottom with a distance. The heat medium (h2, h2*) is circulated in the space W[ti] between the heat insulating materials Ins4, Ins4u and Ins4d, and (ii) the buffer tank Tcs, its upper lid Tcs1 and its bottom and the heat insulating material on the left. Therefore, the temperature control device CL3* for controlling the temperature of the space W[ti] is provided.

(Processing 2)
The residue Re contained in the residue storage tank Tsr due to the execution of the process H2 is urged by the pump Ppt with the valves Va and Vs opened, and the route of Tsr→Lpt→Qdr→Ldr1→Tcs. Along with, and reflux into the buffer tank Tcs. After that, the residue Re that has been refluxed in the buffer tank Tcs is moved along the route of Tcs→Dcbp→Lc0→Qc1→Lc→Sp→Qc2→Ls→Qs→Lsr→Tsr. At that time, the residue Re is urged by the pump Ps with the valve Vbp opened and the valve Vs closed, and the circulation piping path Lc is circulated once or plural times as necessary. As a result, the residue Re is discharged from the buffer tank Tcs, stored again in the residue storage tank Tsr, and is generally circulated between the residue storage tank Tsr and the buffer tank Tcs.

After performing the above circulation at least once, finally, the residue Re is stored in the residue storage tank Tsr, the valves Va and Vs are closed, and the residue Re is stored in the residue storage tank Tsr for a predetermined period. To do. Here, the predetermined period is synonymous with the predetermined period in the process 1. In general, as the number of times of circulation described above increases, the effect of reducing or removing the volume of the residue Re from the buffer tank Tcs, the pipe Lc0, the circulation pipe line Lc, and the disinfectant pipe line Ls from the position Qc2 to the position Qs becomes higher. Therefore, it is desirable to circulate it twice or more.

When the residue Re that has been refluxed in the buffer tank Tcs is to be stored in the residue storage tank Tsr again, (a) fresh water ws is additionally supplied to the buffer tank Tcs from the water supply section S[ws]. , Thereby, the residue Re existing in the buffer tank Tcs, in the pipe Lc0, in the circulation pipe line Lc and in the germicide pipe line Ls from the position Qc2 to the position Qs may be diluted with fresh water ws or washed or washed away. .. Thereby, the volume or removal of the residue Re can be performed more effectively (however, since the capacity of the residue storage tank Tsr has an upper limit, the residue storage tank Tsr can be added as necessary. After moving the contents of to another location, additional supply of fresh water ws).

At that time, (b) a low concentration neutralizing agent An* may be injected from a position Qn in the middle of the water supply conduit Cws and supplied into the buffer tank Tcs in a state diluted with fresh water ws. .. Supplying a low concentration of neutralizing agent An* helps to detoxify (i) free available chlorine existing in the residue Re or generated from the residue, or the neutralizing agent An* and the free In the process of reaction with available chlorine, in the buffer tank Tcs, in the pipe Lc0, in the circulation pipe line Lc and in the residue Re existing in any place in the disinfectant pipe line Ls from the position Qc2 to the position Qs. It promotes the dissolution and exfoliation of the residue Re that has been deposited, deposited or solidified at any place, and enhances the effect of reducing or removing the volume of the residue Re that exists at any place, and (ii) the release It helps to reduce the amount of heat generated during the reaction between available chlorine and the neutralizing agent An*.

3.3) Adiabatic Design of Solution Manufacturing Department S[pr] FIG. 37 is an explanatory diagram of Example-M of the water treatment device according to the present invention. Example-M is a water treatment device D installed on the pedestal Bp arranged on the floor Bv at the installation location ER in the ship VSL, and like Example-H to Example-L, i) Hopper part S[hp], water supply part S[ws], solution manufacturing part S[pr] including mixing part S[mx] and dissolution promoting part S[st], and bactericide injection part S[ is].

Unlike Example-H to Example-L, in Example-M, the mixing section S[mx] and the dissolution promoting section S[st] share a temperature setting mechanism. Specifically, (i) The entire solution production section S[pr], and thus both the mixing section S[mx] and the dissolution promoting section S[st] are installed in a single adiabatic space W[u], and (ii) adiabatic space W[ The temperature adjusting device CL(u) is provided for adjusting or setting the temperature in [u] to set or control the temperature Tcs and the temperature Tas within a specific temperature range. The temperature setting mechanism provided in the hopper unit S[hp] is not limited to the modification 5 shown in FIG. The temperature control device CL(u) is a known device having at least a cold heat generating function, and is preferably a known device having both a cold heat generating function and a warm heat generating function.

The solution manufacturing unit S[pr] in the first embodiment may be installed in the heat insulating space W[u] illustrated in FIG. 37. In that case, a through hole may be provided in the heat insulating material Ins7 above the heat insulating space W[u] so that the rotating shaft Axi can be inserted, and the drive motor Mti can be installed above the heat insulating material Ins7 above. A representative example of the water treatment device D configured in this manner is Example-E.

The upper heat insulating panel IP(u) is divided into two parts before mounting, as shown in FIG. This is to facilitate installation. Therefore, the top insulation panel IP(u) may be an undivided unitary piece if it is not difficult to mount.

The upper surface insulation panel IP(u) has an opening at a position corresponding to the lid for facilitating the operator's access to the lid attached to the end opening of the raw material supply port Crf provided in the hopper H. When mounting the uppermost heat insulating panel IP(t) on the upper heat insulating panel IP(u), the heat insulating material Ins1* attached to the panel board P is inserted into the opening of the upper heat insulating panel. When removing the uppermost heat insulating panel IP(t) from the upper heat insulating panel IP(u), the heat insulating material Ins1* is pulled out from the opening.

The use of the uppermost heat insulating panel IP(t) is not essential for inserting the heat insulating material Ins1* into or removing from the opening of the upper heat insulating panel. The heat insulating material itself not attached to the panel board P may be used as the heat insulating material Ins1* to fill the opening or be taken out from the opening.

3.6) Improvement Example of Hopper S[hp] When setting or controlling the temperature Th in the hopper H to be equal to or lower than the upper limit of the temperature in the container, it is desirable to keep the humidity in the hopper H lower. This is because if the humidity in the hopper H is low, even if chlorine gas is generated in the hopper H for some reason, metal corrosion is less likely to occur and an irritating odor is less likely to occur. On the other hand, fresh water ws is also supplied from the water supply section S[ws] to the solution manufacturing section S[pr] in which the raw material solids ms (ms*) are charged from the hopper section S[hp]. The moisture derived from the fresh water ws rises through the raw material supply path Cms and the measuring mechanism Mvf, reaches the hopper H, and may increase the humidity in the hopper H. Therefore, hereinafter, an improved example of the hopper section S[hp] that prevents or prevents the moisture derived from the fresh water ws supplied to the solution manufacturing section S[pr] from reaching the hopper H will be described.

(1) Improvement example 1
The supply amount of the gas A1 per unit time is increased by using the discharge support mechanism shown in FIG. As a result, a flow of the gas A1 flowing into the solution manufacturing unit S[pr] through the raw material supply passage Cms is created, and the invasion of water derived from fresh water ws into the hopper S[hp] is prevented. As described above, the temperature of the gas A1 is such that the environmental temperature is equal to or lower than the upper limit of the temperature inside the container. Alternatively, the humidity of the gas A1 supplied into the measuring mechanism Mvf is set as low as possible. Due to these, there is a danger that the raw material solids ms remaining in the measuring mechanism Mvf or the raw material supply path Cms becomes a source of chlorine gas, or the generated chlorine gas contains water and is highly corrosive, causing an irritating odor. It is possible to reduce the risk that

(2) Improvement example 2
FIG. 39 is an explanatory diagram of a second modification of the hopper section S[hp]. In this improvement example 2, the gas A2 is supplied from the inlet Din side into the measuring mechanism Mvf, moved from the outlet Dout to the raw material supply passage Cms, and flows into the solution manufacturing unit S[pr] through the raw material supply passage Cms. By doing so, the invasion of water derived from fresh water ws into the hopper S[hp] is prevented. In the case of the improved example 1, when the supply amount of the gas A2 is increased, a flow that remains in the measuring mechanism Mvf without moving to the raw material supply path Cms from the outlet Dout is formed, and the raw material solids ms remaining in the measuring mechanism Mvf May increase. On the other hand, when the gas A2 is supplied, a gas flow from the inlet Din side to the outlet Dout side is formed, so that the increase in the amount of the raw material solid ms remaining in the measuring mechanism Mvf is suppressed. Or it can be prevented.

In the improved example 2, further, the gas A3 is supplied to the raw material supply passage Cms and is allowed to flow into the solution production section S[pr] through the raw material supply passage Cms, so that the hopper portion S[[ hp] is blocked.

(3) Improvement example 3
(3-1) FIG. 40 is an explanatory diagram of a third modified example of the hopper S[hp], FIG. 40(a) is a front view thereof, and FIG. 40(b) is a side view thereof. In this improved example 3, the tip of the middle or solution produced unit S [pr] side of the feed channel Cms provided a valve Vbl, raw solid ms from the hopper portion S [hp] To a solution prepared portion S [pr] ( When the charging of ms*) is stopped, the valve Vbl is closed to prevent the moisture derived from the fresh water ws from entering the hopper S[hp]. A typical example of the valve Vbl is a ball valve which is known to have a very high shutoff performance. If the degree of automation of the water treatment device D is increased, it is preferable to use an electric ball valve.

(3-2) FIG. 40(c) and FIG. 40(d) are a derivative example 1 and a derivative example of the improvement example 3 of the hopper section S[hp] shown in FIGS. 40(a) and (b), respectively. It is explanatory drawing of 2, and is a side view in each case. In the derivation example 1 of the improvement example 3, by supplying the gas A4 from the side surface of the valve Vbl to the raw material supply passage Cms and flowing into the solution manufacturing section S[pr] through the raw material supply passage Cms, the moisture derived from the fresh water ws is obtained. Prevents entry into the hopper S [hp] of. In the second derivative of the improved example 3, when the valve Vbl is installed at a position separated from the upper lid Ts1 (or Tcs1), the gas A5 is supplied to the raw material supply passage Cms between the valve Vbl and the upper lid Ts1 (or Tcs1). By supplying and flowing into the solution manufacturing section S[pr] through the raw material supply channel Cms, the invasion of water derived from fresh water ws into the hopper section S[hp] is prevented.

1.4) Example When the freighter VSL leaves the first port with an empty cargo, seawater Wo is loaded into the ballast tank BT at the first port, and seawater from the ballast tank BT is loaded at the second port where cargo is loaded. Wt is discharged overboard, then loaded with cargo and returned to the first port. Then, when emptying again from the first port where the cargo was unloaded, when sailing towards the second port, when loading seawater Wo into the ballast tank BT at the first port, first at the first port, Taking seawater Wo into the ship, when circulating the ballast water intake pipe line Lf, the chlorine-based germicide As using the water treatment device according to the present invention as the germicide supply device D from the germicide inlet Is, Inject it into the circulating seawater Wo. Thus, the seawater Wo is sterilized, and the seawater Wo (that is, the seawater Ws) in which the chlorine-based bactericide As is injected is stored in the ballast tank BT. The freighter VSL then departs from the first port, sails and goes to the second port for loading cargo.

During the period Pb shown in FIG. 6 and FIG. 9, after performing the second stage S2 for the sterilization treatment in the first port, the second port, which is the departure destination, returned to the first port. It is almost equal to the period until the second sterilization process is started later in the first port. The same applies to the period Pb*.

The technical scope of the present invention extends to an equivalent range. The meaning or interpretation of each term in the present specification does not prevent the technical scope of the present invention from extending to an equivalent range.
Hereinafter, the inventions described in the claims at the time of filing the present application will be additionally described.
