Description

  The present invention relates to a spraying apparatus capable of mixing and spraying a plurality of liquids at an arbitrary ratio and a spraying method thereof.

  Deodorization is performed by spraying deodorant on the odor source in construction with odor caused by waste or contaminated soil, in homes and hospital rooms where odor is likely to occur. For example, in Patent Document 1, a diluted deodorant liquid whose concentration has been adjusted in advance is created, stored in a water receiving tank, a filter case is immersed in the water receiving tank, and the diluted deodorant liquid is attached to the filter case. The deodorant is diffused by allowing air to pass through the fan.

  Such a method using a diluted deodorant liquid whose concentration is adjusted in advance is to efficiently deodorize odor sources with uniform odor intensity and distribution such as livestock sheds and industrial waste treatment facilities. Can do.

  In constructions involving odors caused by the above-mentioned waste or contaminated soil, the status of the odor source is often unknown, and the strength of the odor often varies depending on the position. When deodorizing by the above method for odor sources where the intensity and distribution of such odors are non-uniform, prepare a plurality of diluted deodorant liquids with different dilution ratios according to the odor intensity, It is necessary to deodorize by switching depending on the position. This has a problem of poor work efficiency.

  Therefore, as in Non-Patent Document 1, the deodorant stock solution and the diluent are mounted in independent tanks, a dilution mixer is provided between the tank and the nozzle, and the concentration setting according to the odor intensity is in operation. A configuration that can be varied is proposed and used.

“Mobile Microgel Spraying Equipment Aquafog”, [online], August 7, 2007, Calmore Co., Ltd. [searched December 26, 2013], Internet <URL: http: //www.karumoa. co.jp/images/product/pdf/mg-210-01_Aquafog.pdf>

  However, as in Non-Patent Document 1, each liquid is put in an independent tank and the concentration setting is made variable according to the intensity of odor. Therefore, it is necessary to select a combination of a deodorant stock solution and a diluting solution that requires a short time for mixing. This is because if the combination is not good, density unevenness occurs and deodorization cannot be performed efficiently. When such a combination is not selected, it is necessary to provide an intermediate tank and perform sufficient mixing in this intermediate tank.

  In the former case, the combination of the deodorant stock solution and the diluting solution is limited, and in some cases, an additive that is not necessary for deodorization, such as a surfactant that improves the mixing property, is necessary. there were. In the latter case, after all the liquid in the intermediate tank has been removed, if the appropriate amount of deodorant stock solution and diluent are not mixed and mixed, the set concentration cannot be reached immediately. There is a problem in that the density response at the nozzle position is impaired.

  Therefore, when a plurality of liquids are mixed and sprayed, any combination of the plurality of liquids or an intermediate tank or the like is provided, and a sufficiently mixed state is obtained until the target position is reached. It is desired to provide an apparatus and a method that can be switched to a set concentration immediately.

  In view of the above problems, the present invention provides a plurality of containers each containing a plurality of liquids, a plurality of tubes each formed in a ring shape and supplied with each liquid from each container, and a plurality of tubes provided for each tube. A plurality of nozzles for spraying the liquid supplied into each tube and a vortex in the arrangement direction of the plurality of tubes arranged so that the holes of each tube formed in a ring shape are arranged in a line A blower that blows air, and a valve that is provided between each tube and each container, and adjusts the flow rate of each liquid supplied from each container to each tube to each set flow rate, A spraying device is provided.

  A step of supplying each liquid from a plurality of containers each containing a plurality of liquids to each of a plurality of tubes each formed in a ring shape; and a step provided between each container and each tube. Adjusting the flow rate of each liquid to a predetermined flow rate by a plurality of valves, and toward the arrangement direction of the plurality of tubes arranged so that the hole portions of each tube formed in a ring shape are arranged in a row, A step of blowing air so as to make a vortex by a blower, a step of spraying each liquid from a plurality of nozzles provided in each pipe, and a flow rate of each liquid are set in accordance with positions to be sprayed by a plurality of valves And a method of spraying is provided.

  By providing the apparatus and method of the present invention, when a plurality of liquids are mixed and sprayed, the target position can be reached without any combination of the plurality of liquids or an intermediate tank or the like. It is possible to obtain a sufficiently mixed state before the change, and it is possible to immediately switch to the set concentration.

  The present invention employs a method in which a plurality of liquids are not mixed before being sent to the nozzle to be sprayed but mixed after spraying, so that a plurality of liquids are used in various combinations regardless of the mixing property of the plurality of liquids. can do. In addition, since it is not necessary to provide an intermediate tank, the concentration can be changed immediately. For this reason, it is possible to reduce a decrease in density response at the nozzle position. Hereinafter, a specific configuration will be described.

  FIG. 1 is a diagram showing a schematic configuration of the spraying apparatus of the present embodiment. The plurality of liquids may be any liquid, but here, when using two deodorant stock solutions used for deodorization and a diluting solution for diluting the deodorant stock solution Will be described. As the deodorant stock solution and the diluting solution, those having appropriate components can be adopted depending on the purpose of use. As an example of the deodorant stock solution, a solution containing hypochlorous acid as a main component can be given as an example, and as its diluent, water can be mentioned. Since these are examples, the deodorant stock solution may be any solution as long as it has a deodorizing effect, and the diluent may be any solution as long as the stock solution can be diluted.

  The spraying device 10 includes a stock solution tank 11 as a container for housing the deodorant stock solution, and a diluent tank 12 as a container for housing the diluted solution. These tanks may have any shape, structure, and material as long as they can accommodate a required volume of each liquid. However, when the liquid to be used is a liquid having a corrosive property, a container manufactured from a corrosion-resistant material is used.

  The spray device 10 also includes a plurality of tubes 13 and 14 formed in a ring shape. The tubes 13 and 14 are formed in a donut shape, and a substantially circular hole is formed in the center. The pipe 13 is connected to the stock solution tank 11 by a conduit (line) 15, and the pipe 14 is connected to the diluent tank 12 by a line 16. Therefore, the tube 13 is supplied with the deodorant stock solution from the stock solution tank 11, and the tube 14 is supplied with the diluent from the diluent tank 12.

  The sizes of the tubes 13 and 14 may be the same size or different sizes. The inner diameters of the tubes 13 and 14 can be appropriately sized according to the flow rate of the liquid to be sprayed. The pipes 13 and 14 may be made of any material such as plastic resin, carbon steel, stainless steel, copper, etc., but when using a corrosive liquid as described above, it is manufactured from a corrosion-resistant material. Pipes are used. In addition, the shape of the tubes 13 and 14 formed in a ring shape may be circular or elliptical.

  The tubes 13 and 14 are arranged so that their holes are arranged in a row in the horizontal direction. The arrangement interval can be set to an arbitrary interval. The pipes 13 and 14 are provided with a plurality of nozzles 17 and 18 protruding from the pipes 13 and 14 in the arrangement direction. The plurality of nozzles 17 provided in the pipe 13 have one or more small holes at the tip, and can spray (spray) the deodorant stock solution supplied into the pipe 13 in the form of a mist. Yes. The plurality of nozzles 18 provided in the tube 14 also have one or more small holes at the tip so that the diluent supplied in the tube 14 can be sprayed. The arrangement in such a manner that the two liquids are sufficiently mixed in the atmosphere by the air swirling when the air is blown by the blower 19 described later so as to swirl. It is to make it.

  In the middle of the lines 15 and 16, valves 20 and 21 for adjusting the flow rate of each liquid are provided. The valves 20 and 21 may be any type of valve such as a globe valve or a ball valve as long as the flow rate of each liquid can be adjusted. The valves 20 and 21 may be manually adjusted, but electromagnetic valves that can be automatically adjusted to a set flow rate can also be used. By providing these valves 20 and 21, the mixing ratio of the deodorant stock solution and the diluent can be changed.

  Here, the significance of changing the mixing ratio of the deodorant stock solution and the diluent will be described with reference to FIG. When the odor intensity is uneven depending on the location, it is known that changing the concentration according to the location is advantageous in terms of cost in order to suppress the odor therefrom.

  For example, it is assumed that a certain deodorant is sprayed on soil where heavy oil has leaked. As shown in the number of spraying times 2 in FIG. 2, if the spray amount is the same, the deodorant diluted 20 times is more highly deodorized than the deodorant having a low concentration diluted 100 times. Can do. That is, the odor level can be lowered to level 2 lower than level 3.

  However, if it is not required to reduce the level to 2, the result of level 3 is the same for both a strong deodorant and a low concentration deodorant, as shown in the number of sprays once in FIG. This is due to the fact that the human sense of odor is non-linear. Then, if level 3 is acceptable, it can be said that it is useless to spray a dark deodorant over the entire area to deodorize it, and it is very useful to change the concentration depending on human senses. .

  For this reason, in this invention, the odor level of an odor source can be judged with a human sense, and said mixing ratio can be changed according to the odor level. The mixing ratio can be changed by changing the flow rates of the deodorant stock solution and the diluent to be set.

  Referring again to FIG. 1, the spray device 10 includes a blower 19 arranged in a line with the tubes 13 and 14. The blower 19 blows air so as to make a vortex toward the tubes 13 and 14 arranged in a row. Examples of the blower 19 that blows air so as to wind a vortex include an axial flow fan and a mixed flow blower that have a plurality of blades and allow air to flow in from the axial direction and flow out in the axial direction. Since there are only two pipes 13 and 14 in the blowing direction of the blower 19, the compression ratio is small, and therefore a fan can be used instead of a blower.

  In the blower 19, a plurality of blades are attached at regular intervals around the shaft so as to be inclined with respect to the arrangement direction which is the same direction as the axial direction, and the shaft is rotated by a motor at a constant rotational speed, thereby generating a vortex. Air is blown to wind. As a result, the liquid sprayed from the plurality of nozzles 17 and 18 of the two tubes 13 and 14 arranged in the arrangement direction is appropriately and sufficiently mixed in the atmosphere due to the stirring effect of the air blown so as to vortex. Thus, the odor source that is the target position can be reached and deodorization can be performed efficiently.

  It is possible to adopt a configuration in which one or a plurality of nozzles are appropriately arranged without providing the tubes 13 and 14, but with one, it takes time to deodorize and deodorizes only a narrow range at a time. I can't. When arranging multiple nozzles appropriately, lines connecting to each nozzle are required, and the lines become complicated, and each line blocks air flow and disturbs the air flow. It becomes impossible to blow in one direction. In this case, the above stirring effect cannot be obtained. For this reason, in the present invention, pipes 13 and 14 formed in a ring shape are used so that the air blown while swirling is generated as much as possible, and a plurality of nozzles 17 and 18 are provided in the pipes 13 and 14. Is provided.

  In addition, it is possible to use a blower that simply blows air in a certain direction, such as a centrifugal fan, but this centrifugal fan cannot be blown in a vortex, and therefore reaches the target odor source. Until fully mixed. In this case, even if sprayed to the odor source, the concentration of the deodorant is uneven, and the deodorization cannot be performed efficiently. For this reason, in this invention, the air blower 19 which ventilates so that a vortex, such as an axial flow fan, may be used.

  In the embodiment shown in FIG. 1, the stock solution tank 11 and the dilution solution tank 12 are at a high position, and each solution is supplied directly from each tank to each tube 13, 14 via the valves 20, 21. A pump is provided in each line 15 and 16, and each liquid can also be pumped. In addition, each liquid can be appropriately sprayed from a nozzle by pumping each liquid with a pump. The pump may be any pump such as a centrifugal pump or an axial flow pump as long as the liquid can be pumped.

  FIG. 3 is an enlarged view of the pipe 13 and a plurality of nozzles provided in the pipe 13. FIG. 3A is a plan view seen from the arrangement direction, and FIG. 3B is a side view thereof. The tube 13 is formed in a ring shape as described above, and includes a protruding connection port 22 for connecting the tube 13 and the line 15. Since the tube 14 and the plurality of nozzles 18 and connection ports 23 provided in the tube 14 are the same as the tube 13 and the plurality of nozzles 17 and connection port 22, description thereof is omitted.

  The connection port 22 has a hollow cylindrical shape protruding from the tube 13. When a rubber hose is used for the line 15, it can be connected by inserting the rubber hose. In other cases, a connection jig such as a socket is used. And can be connected to the line 15. The connection port 22 may have any shape or structure as long as it can be properly connected to the line 15. The connection port 22 can also be connected to the line 15 by welding or welding.

  In the tube 13, a plurality of nozzles 17 protrude from the tube 13 at regular intervals as shown in FIG. 3 (a) on a surface (surface on the side not the blower 19 side) facing in the arrangement direction of FIG. 3 (b). To be provided. In FIG. 3A, eight nozzles 17 are provided at equal intervals. The nozzle 17 can be bent at the connection portion with the tube 13 and can be inclined with respect to the arrangement direction. The spraying direction can be changed by changing the angle θ that is inclined with respect to the arrangement direction. Note that the angle θ may be changed using other methods and members. Thereby, it can adjust so that it may become a vortex of a desired diameter.

  Since the liquid sprayed from the nozzle 17 moves in the atmosphere so as to spiral while reaching the odor source, each liquid can be sufficiently mixed in the atmosphere. The sprayed liquid moves so as to draw a large vortex as it moves away from the nozzle 17. For this reason, when the tubes 13 and 14 are formed to have the same size and the angle θ of the nozzles 17 and 18 is set to the same angle with the tubes 13 and 14, a portion that does not mix comes out, and the liquid in that portion is wasted. become. Therefore, the angle θ can be changed and adjusted so that no part is not mixed.

  The pipes 13 and 14 provided with the plurality of nozzles 17 and 18 can be arranged in a hollow cylindrical casing 30 as shown in FIG. 4 using a support member (not shown). For example, the support member is fixed to the inner wall of the casing 30 and extends from the inner wall toward the center of the diameter so as not to block the passage of the air blown so as to wind as much as possible. It is possible to use at least three rod-like members each having a holding portion that can hold the pipes 13 and 14. The pipes 13 and 14 can be disposed in the central portion of the diameter of the casing 30 as shown in FIG. The arrangement method of the supporting member and the tubes 13 and 14 illustrated here is an example, and is not limited to this.

  The casing 30 is composed of two cylindrical members 30a and 30b, and can be connected by screwing them together. The tube 13 is disposed in the cylindrical member 30a, and the tube 14 is disposed in any position in the cylindrical member 30b. For example, the cylindrical member 30b is fixed and the cylindrical member 30a is rotated in the direction indicated by the arrow. Can be screwed together. By adjusting the number of rotations of the cylindrical member 30a, the interval between the tube 13 and the tube 14 can be adjusted. In addition, the cylindrical member 30b in which the pipe | tube 14 is arrange | positioned can be connected with the air blower 19 using means, such as a flange connection.

  The cylindrical members 30a and 30b of the casing 30 may have the same diameter in the length direction, or may have diameters that increase from the cylindrical member 30b toward the cylindrical member 30a. Further, here, the configuration in which the interval is adjusted by screwing is illustrated, but any structure or configuration such as a slide structure may be adopted as long as the interval can be adjusted.

  Even if the flow rate is adjusted by the valves 20 and 21 and the angles of the nozzles 17 and 18 are adjusted, the unmixed portion cannot be completely eliminated. In order to further reduce this portion, the distance between the tubes 13 and 14 can be adjusted. Note that the adjustment of the mixed state may be only the adjustment by the valves 20 and 21, only the adjustment of the angle of the nozzles 17 and 18, or only the adjustment of this interval. Further, the mixing state can be adjusted by adjusting two or more of them.

  With reference to FIG. 5, the flow of the process of spraying a plurality of liquids using the spray device 10 will be described. This process starts from step 500. First, in step 505, when used, the pump is started, and the deodorant stock solution is supplied from the stock solution tank 11 and the dilution solution is supplied from the dilution solution tank 12 to the pipes 13 and 14, respectively. In step 510, the flow rate of each liquid is adjusted by the valves 20 and 21 so that a predetermined flow rate is obtained. The predetermined flow rate is the flow rate of the deodorant stock solution and the dilution solution set when deodorizing is performed at that position. These flow rates can be determined from the mixing ratio of the deodorant stock solution and the diluent.

  In step 515, air is blown by the blower 19 in a direction of the arrangement of the tubes 13 and 14 arranged in a row. In step 520, the deodorant stock solution and the diluted solution whose flow rates are adjusted by the valves 20 and 21 are sprayed from a plurality of nozzles 17 and 18 provided in the tubes 13 and 14. The sprayed deodorant stock solution and diluent move toward the target deodorant source while thoroughly mixing in the atmosphere. A deodorant appropriately diluted with a diluting solution is deodorized by chemically reacting with a component that is a source of malodor in the odor source or by enclosing the component. The deodorizing method may be a method other than chemical reaction or wrapping.

  In step 525, it is determined whether or not the deodorization at that position has been completed by human sense. If the deodorization is successful, in step 530, the supply of the deodorant stock solution and the diluent is once stopped. For example, it can be stopped by closing the valves 20 and 21. In step 535, it is determined whether there is another position to be deodorized, and if there is, the process proceeds to step 540. If deodorization is not completed in step 525, spraying of each liquid is continued until deodorization is possible.

  In step 540, supply of the deodorant stock solution and diluent once stopped to the pipes 13 and 14 is started. In step 545, the flow rate of each liquid is set according to the odor level at other positions, and the setting is made. The flow rates of the respective liquids are changed by the valves 20 and 21 so as to obtain the respective flow rates. And it returns to step 515, each liquid is sprayed from the some nozzles 17 and 18, and the deodorizing of the said other position is performed.

  In this way, when there is no other position to be deodorized, the process proceeds to step 550, the supply of the respective liquids and the blowing are stopped, and the process is terminated in step 555. Judgment of deodorization may be made by human senses, but it can also be performed by using an odor measuring device such as an odor meter and determining whether the level is below a predetermined level.

  From the above, the device and method of the present invention, when used for spraying a deodorant, continues spraying in an uneven situation where the intensity of odor such as illegal dumping or soil contamination changes depending on the position. It becomes possible to change the setting to an appropriate deodorant concentration that responds quickly to changes in the situation. Even when applied to other than deodorants, mixed spraying is possible even with a combination of multiple liquids that are inferior in mixing properties, and it is possible to change the concentration to a set concentration immediately without using an intermediate tank, etc. it can.

  So far, the spraying apparatus and spraying method of the present invention have been described in detail with reference to the embodiments shown in the drawings, but the present invention is not limited to the above-described embodiments, and other embodiments, Additions, changes, deletions, and the like can be made within the scope that can be conceived by those skilled in the art, and any embodiment is included in the scope of the present invention as long as the effects and advantages of the present invention are exhibited.
