  In recent years, it has been studied that carbonated water in which carbon dioxide gas is dissolved at a high concentration in water or warm water has various effects on the human body and agricultural products, and certain demonstration examples have been published. A carbonated spring (“carbon dioxide spring”) hot spring has been known as a familiar example since it has been effective in relieving fatigue. It is said that the effects of carbonic acid components on the body can be expected to permeate through the skin, promote blood circulation, discharge waste products, eliminate swelling, and improve fatigue recovery by drinking, and improve diabetes, gout, and anemia. ing.

  Furthermore, even if it is used as hydroponics water, soil washing water, or agricultural water, growth of crops is promoted, and when used as washing water for poultry houses and cowsheds, it is not only for animals but also for workers. Studies have been published that improve hygiene.

  Such a carbonated water generator that can be expected to be effective in various fields has been developed and proposed.

  For example, as a method and apparatus for dissolving carbonic acid in water using a mechanical device, Japanese Patent Application Laid-Open No. 2001-293344, “Carbonated Water Production Apparatus and Carbonated Water Production Method” (Patent Document 1) discloses carbon dioxide from a carbon dioxide gas cylinder. Disclosed is a method for dissolving a gas in water using a membrane-type carbon dioxide dissolver such as a hollow fiber membrane (a method for dissolving carbon dioxide by a membrane). Japanese Patent Application Laid-Open No. 2004-305286, “Method and Apparatus for Dissolving Carbon Dioxide Gas” (Patent Document 2) discloses a method for dissolving carbon dioxide gas from a carbon dioxide gas cylinder as fine bubbles using an injector (dissolving carbon dioxide gas by fine bubbles). Dissolution method) is disclosed. Japanese Patent Laying-Open No. 2009-195812 “Carbonated water production apparatus” (Patent Document 3) discloses an apparatus in which water injected with carbon dioxide gas is pressurized and pressurized to a pressurizing unit to dissolve the carbon dioxide gas in water.

  However, the method for dissolving carbon dioxide with a membrane disclosed in Japanese Patent Application Laid-Open No. 2001-293344 (Patent Document 1) has a problem that the membrane is clogged due to generation of scale and / or bacteria, and the carbon dioxide cannot be dissolved. . In addition, the method for dissolving carbon dioxide gas using fine bubbles disclosed in Japanese Patent Application Laid-Open No. 2004-305286 (Patent Document 2) has a problem that a large apparatus is required and the production cost of carbon dioxide gas is high. In addition, the disclosure of Japanese Patent Application Laid-Open No. 2009-195812 (Patent Document 3) needs to include a pressure dissolving part and a pressure reducing part that are dissolved in water by pressurization, and there are many components and the control becomes complicated. There was a problem that was not suitable for home use. Further, the disclosure of Japanese Patent Application Laid-Open No. 2008-212495 (Patent Document 4) has a problem that the production capacity of the carbon dioxide gas dissolving part increases because the pipe length becomes longer, the ability to generate carbonated springs decreases, and the internal structure is complicated. was there.

  Further, carbonated water is produced by the generation and dissolution of carbon gas by electrolysis of water using the carbonaceous electrode disclosed in Japanese Patent Application Laid-Open No. 08-196456 (Patent Document 5) and Japanese Patent Application Laid-Open No. 08-252192 (Patent Document 6). However, it is difficult to produce high-concentration carbonated water suitable for a carbon bath.

  Therefore, the present invention solves the above-described problems, and uses a gas dissolver in which the mixing channel length for performing gas dissolution is short and the production capacity of carbonated water does not decrease even with a simple structure, and the same. An object is to provide a carbonated water generator.

  The gas dissolver according to the present invention has a flat partition plate in which a concave portion or a convex portion is formed on one or both surfaces, and the partition plate is disposed facing each other with a predetermined separation distance, and the periphery of the partition plate is hermetically sealed. It is characterized by comprising a gas-liquid mixing area that is sealed to form a partition space, and an inflow port and an outflow port of a fluid that communicates with the separated positions of the gas-liquid mixing area.

  According to the present invention, the flow flowing through the gas-liquid mixing zone partitioned by the partition plate facing with a predetermined separation distance in which the concave portion or the convex portion (hereinafter referred to as “concave portion”) is formed collides with or interferes with the concave and convex portion. As a result, a turbulent state is formed and the dissolution of the gas in water can be promoted. The predetermined separation distance is set such that the flow particles (fluid particles) can reciprocate a plurality of times between the partition plates from the inlet to the outlet. That is, it is set in consideration of various factors such as the flow velocity, the protruding height of the concavo-convex portion, the motion behavior of particles exhibiting a turbulent state, the stirring state, the area of the partition plate, and the viscosity resistance of water. For example, if the area of the partition plate can be set wide from 1 mm to 3 mm, it may be set from 3 mm to 10 mm. The positional relationship between the inlet and the outlet is set so as to be the farthest path in the gas-liquid mixing area. In addition, when the direction change board for bypassing a flow is provided in a gas-liquid mixing area | region, it arrange | positions considering this.

  Further, in the gas dissolver according to a second aspect of the present invention, the convex / concave portion has a ridge shape or a groove shape, and the extension direction thereof and the streamline direction flowing through the gas-liquid mixing region obliquely intersect with each other. It is characterized by being.

  According to the present invention, since the uneven portion is formed in a continuous shape and is arranged so as to obstruct the flow, it does not follow the shortest path from the inflow port to the outflow port in the direction along the ridge or groove of the uneven portion. This leads to a longer residence time in the gas-liquid mixing zone. As a result, the flow particles (water molecules and carbon dioxide bubbles) are further agitated, and the dissolution of carbon dioxide (or carbon dioxide) can be promoted.

  In the gas dissolver of the invention according to claim 3, the ridge-like or groove-like convex part or concave part is repeatedly formed in parallel and at equal intervals, and the repetition period of the concave and convex parts facing each other is the same or different. It is characterized by a period.

  According to the present invention, the flow particles move up and down along the concavities and convexities facing each other, and stirring and mixing are promoted. And when the period is different, more complicated behavior is induced, and the mixing property and the stirring property can be further improved.

  Moreover, the gas dissolver of the invention according to claim 4 is characterized in that the facing arrangement of the partition plates in which the concavo-convex portions are formed with the same period is an arrangement with the same period or an arrangement with a half-cycle deviation. To do.

  According to this invention, when the repeated periods of the concavities and convexities facing each other are arranged so as to coincide with each other, the vertical movement of the (wave-like) flow particles along this can be made more active and the mixing property and the stirring property are improved. be able to. In addition, facing arrangement in a state shifted by a half cycle, i.e., when the convex part and the concave part are arranged to face each other, an expansion space and a narrow space are formed in the formed space. A compression force and an expansion force can be repeatedly applied. As a result, friction between particles and particle splitting are induced, so that the gas can be further dissolved into the liquid, that is, gas-liquid water in which carbon dioxide is dissolved at a high concentration can be generated.

  A gas dissolver according to a fifth aspect of the present invention is one of the main points of the present invention, and is characterized by a multilayer structure in which a plurality of gas-liquid mixing regions are stacked.

  According to this invention, it is possible to reduce the size of the gas dissolver without lowering the function, and to increase the degree of freedom of installation. That is, if the volume of the gas-liquid mixing zone is wide, the solubility of the gas will increase accordingly, but in the single-layer gas-liquid mixing zone formed only by the facing of the two partition plates, a wide occupied area is obtained. It becomes necessary and lacks compactness (space saving property) and installation property. For this reason, by forming a multilayer structure in which a large number of the bubble mixing regions are stacked, the size can be reduced without impairing the dissolution function.

  Furthermore, the carbonated water generating apparatus of the invention according to claim 6 includes a gas dissolver having the above-described configurations and water and carbon dioxide (CO2) separately in the gas-liquid mixing zone of the gas dissolver, or An injection pipe connected to the inlet for supplying after joining, and an outlet pipe connected to the outlet for supplying carbonated water generated by the gas dissolver to the outside. is there.

  According to the present invention, carbon dioxide gas can be efficiently dissolved with only a water pressure and a supply pressure of carbon dioxide gas with a simple structure and without applying external energy such as pressurization or electricity.

  Moreover, the carbonated water generating apparatus of the invention according to claim 7 uses heated water instead of room temperature water as water (medium) for injecting into the carbonated water generating apparatus specified in claim 5 and melting carbon dioxide gas. It is characterized by this.

  According to the present invention, carbon dioxide gas can be more efficiently dissolved in water. For example, by appropriately setting the temperature of water, the generated carbonated water can be used as it is as bathing water or at a high temperature. Can be used as hot water for bath water. It can also be used as effective high-temperature sterilizing water or high-temperature disinfecting water.

  According to the present invention of each configuration described above, the gas-liquid mixed with the gas and the medium to be dissolved (water) passes through the gas-liquid mixing area in the narrow space formed by the facing of the partition plate having a predetermined area, Since it reaches from the inflow port to the outflow port, a turbulent state is formed between the planning plates, and the particles are further agitated, so that the degree of dissolution of the soluble gas (such as carbon dioxide) in the liquid can be increased.

  In addition, the gas can be efficiently dissolved in a space-saving manner by making the gas-liquid mixing zone multi-layered.

  Further, the carbonated water generation apparatus using the gas dissolver having the above-described configuration is a carbon dioxide supply means (for example, a gas cylinder filled with carbon dioxide (hereinafter referred to as a gas cylinder filled with carbon dioxide) that can adjust the supply pressure to the inlet of the tap water and the gas dissolver. , "CO2 gas bottle"), it can be easily connected to the pipes of tap water and hot water supply facilities in general households. Only the supply pressure (or water pressure in the case of water supply use) and the gas pressure from the carbon dioxide cylinder do not require additional external energy (for example, additional pressure from the compressor or additional power from an external power source). As a result, it is possible to obtain a carbonated water that is simple, easy and continuous, and that is easy to control and safe, thereby reducing the installation cost of the apparatus and the maintenance cost for maintenance management. Door can be.

It is the schematic which shows the Example (henceforth "this Example apparatus") of the carbonated water production | generation apparatus which concerns on this invention. It is a perspective view which shows the example (henceforth "this example dissolver") of the gas dissolver based on this invention used for this apparatus Example by a partially notched cross section. The cross section of a present Example dissolver is shown, (A) is a cut end view in the central longitudinal direction of the dissolver, and (B) is a partially enlarged view showing a part of (A) in an enlarged manner. . The other Example of the division board of a present Example dissolver is shown, (A) is the example of repeated formation of 2 types of convex-convex parts, (B) is the parallel repeated formation of a ridge-like or groove-like uneven part. It is a perspective view which shows an example and (C) the example formed so that this might cross | intersect the direction of a flow at a predetermined angle. It is the schematic which shows schematic structure of the specific usage example of a present Example apparatus.

  Next, an example of a specific embodiment of a gas dissolver according to the present invention and a carbonated water generation apparatus using the gas dissolver will be described in detail with reference to the drawings.

  1 and 5 are schematic views showing an embodiment of the present apparatus. The carbonated water generator 1 is connected to an inlet 21 of a gas dissolver 2 which is a main component, and a water injection pipe 3a serving as an inflow pipe 3 for supplying water or hot water from a tap water or a water heater, and an outlet. 22 is connected to an outflow pipe 4 piped to an external device 5 (a bathtub 51, a shower head 52, a faucet 53, or the like). In addition, in order to supply carbon dioxide gas from the carbon dioxide gas cylinder 6 to the vicinity of the inlet 21 to the inlet pipe 3, gas supply as the inlet pipe 3 via the T-shaped joint 3c (commonly called “cheese”) and the regulating valve 3d. The pipe 3b is connected.

  With this configuration, the carbon dioxide gas supplied from the carbon dioxide gas cylinder 6 and the water or hot water flowing through the water injection pipe 3 are merged by the T-shaped joint 3 c and introduced into the gas dissolver 2. And, by the action of the partition plate 23 constituting the gas-liquid mixing zone 7 which will be described later, the carbon dioxide gas dissolves in water and becomes carbonated water and flows out from the outlet 22 and passes through the connected outlet pipe 4 to the outside. It is supplied to the faucet 53 as the bathtub 51 and the shower head 52 of the equipment 5 and further as disinfecting water or cleaning water.

  In the present embodiment apparatus, the supply pressure (water pressure) from the water injection pipe 3a as the water inflow pipe 3 is the water supply pressure or hot water supply pressure from the existing public water supply or individual hot water supply equipment, for example, 0.05 to 0.5 Mpa. It is used by adjusting appropriately within the range. Further, the gas pressure from the carbon dioxide gas cylinder 6 is appropriately adjusted within the range of 0.15 to 0.4 Mpa by the adjusting valve 3d.

  In addition, it can be generated easily and easily in a short time without requiring electric power or dynamic pressure to be additionally supplied from the outside using only water pressure or hot water supply pressure and gas supply pressure as an energy source. In addition, because the entire structure is compact (volume saving), if only a carbon dioxide gas cylinder is procured and installed, carbonated water, which is said to have various human effects and effects, can be used in ordinary households. It can be used easily and easily.

  Next, the gas dissolver which is a main element for carbonated water generation will be described with reference to FIGS. The gas dissolver 2 is formed by partitioning plate plates 23 (mainly made of metal or resin) having a predetermined area and facing each other in parallel with a predetermined separation distance. In this embodiment, the separation distance is set to about 1 mm to 5 mm, for example. This is appropriately set depending on the flow rate of water and carbon dioxide to be injected, the flow rate, the distance between the flow paths, and the specifications of the desired dissolved state. Furthermore, the gas-liquid mixing zone 7 is formed by sealing the air gaps 24 around the partition plates 23 and 23 facing each other by welding or by interposing another member therebetween.

  In the vicinity of both ends of the gas-liquid mixing region 7 or at a position where the flow channel faces, an inlet 21 (single in the drawing) that connects the inflow pipe 3 through an appropriate joint (elbow, swivel, etc.). And the outflow port 22 for connecting the outflow pipe 4 to each other. As a position where the flow paths face each other, a diverting plate (not shown) for forming a detour flow path (for example, a U-shaped flow path, a W-shaped flow path, etc.) inside the gas-liquid mixing zone 7 ) Or the like is preferably provided with the farthest possible opposing distance of the gas-liquid mixing region 7. In addition, when the U-shaped detour flow path is formed in the gas-liquid mixing area 7, the inlet 21 and the outlet 22 are adjacent to each other.

  Further, an uneven portion 23 a is formed on the surface of the partition plate 23 that partitions the gas melting region 7. The concavo-convex portion 23a is formed by repeating a continuous ridge shape (or ridge shape) and groove shape in parallel at regular intervals. It has a so-called striped (or corrugated) appearance. Further, the extending direction (formation direction) of the continuous ridges and grooves is formed so as to obliquely intersect the line segment connecting the inflow port 21 and the outflow port 22. This crossing angle is appropriate. As a result, the flow is disturbed by the concavo-convex portion 23a and becomes a turbulent state, and the flow particles (water particles and carbon dioxide gas bubbles) entering from the inflow port 21 are disturbed to promote stirring and mixing, and the outflow port 22 will be reached. Further, the obstruction of this flow has an effect of promoting the dissolution of carbon dioxide gas in water by lengthening the residence time in the gas-liquid mixing zone 7 and extending the stirring time. In this process, carbon dioxide gas dissolves in water and is in an unstable state, but hydrogen carbonate ions HCO3− and hydrogen ions H + are generated in water. It is said that various effects and effects can be expected when used as drinking water or as bath water depending on the abundance ratio of these ions.

  Further, in the present embodiment shown in the figure, the gas-liquid mixing zone 7 is formed in multiple layers as specified in claim 4. That is, a plurality of gas-liquid mixing regions 7 formed by separating the two partition plates 23 and 23 from each other are overlapped to form a multilayer structure. In the case of this multi-layer structure, the inlet 21 and the outlet 22 are formed so as to penetrate each layer, and the particles (water particles and carbon dioxide gas bubbles) of the flowed in flow through each layer evenly. The configuration is taken into consideration. Although illustration is omitted, for example, the opening diameter of the penetrating inlet 21 is increased as the distance from the connecting portion of the inflow pipe 3 is increased, or a current-transforming plate or a partial shielding plate is provided in the inlet 21. You may do it.

  Each of the partition plates 23, 23,... Arranged in multiple layers so as to overlap each other with a predetermined interval (this interval or different intervals) is repeatedly formed (repeatedly formed) at regular intervals as described above. Above, it is formed in a so-called striped pattern or wave pattern. Further, the partition plates 23, 23,... Repeatedly formed in such a pattern may be formed with the same period or different periods, and the facing arrangement is performed by matching the period of the concavo-convex part 23a. Alternatively, they may be arranged in a shifted state. In the embodiment shown in FIG. 3, the partition plates 23 in which the concave and convex portions 23a are formed in the same cycle are arranged facing each other with a half cycle shift. In other words, it is an arrangement in which the convex portions 23ax and the concave portions 23ay face each other. By arranging in this way, an expansion space 7 a and a narrow space 7 b that are periodically repeated are formed in the space of the gas-liquid mixing region 7.

  By repeating expansion and narrowing in this way, compressive force and expansion force are periodically added to the flow particles, thereby inducing friction between particles and particle splitting. Thereby, the melt | dissolution to the liquid (water or warm water) of gas (carbon dioxide gas) is accelerated | stimulated, and a high concentration carbon dioxide solution (carbonated water) can be obtained.

  Next, the partition plate 23 is not limited to the above configuration, and may be formed in various uneven shapes as shown in FIG. For example, as shown in (A), two or more (or more) top surfaces may be formed on the projection-like uneven portion 23b, and may be formed in a matrix or randomly with appropriate specifications. Moreover, as shown to (B), it is good also as the line-shaped uneven | corrugated | grooved part 23c which interrupted the continuation of the ridge or the groove | channel. This may promote the flow. In particular, when the separation distance of the partition plate 23 is narrowed, it is effective to secure a predetermined flow rate. Furthermore, as shown in (C), when the parallel repeated formation of the ridge-like or groove-like uneven part is arranged obliquely intersecting with the flow direction, the longitudinal center part (or a plurality of longitudinal parts) of the partition plate 23 The direction may be changed at the direction line portion. You may form in a so-called arrow feather-like pattern on the external appearance.

  In addition, the combination at the time of multilayering of the partition plates 23 is appropriately determined in consideration of the shape of the uneven portion 23 and the separation distance in each layer in consideration of the area of each partition plate, the pressure of the influent, the temperature, or the required solubility. Is to be selected.

[Verification data]
Next, the verification data which tested the productivity state of carbonated water using the said Example apparatus is shown below. Tables 1 to 3 show the solubility and carbon dioxide concentration when the temperature of the influent water is changed using three patterns of the influent water amount and water pressure, and the carbon dioxide gas flow rate and gas pressure. 4 shows the solubility and carbon dioxide concentration when the flow rate of carbon dioxide gas is changed at a constant gas pressure with the amount and temperature of the influent water being constant.

The present invention relates to a gas dissolver for dissolving carbon dioxide (CO2) in water (or hot water) at a high concentration, and a carbonated water generation apparatus using the same.

  In recent years, it has been studied that carbonated water in which carbon dioxide gas is dissolved at a high concentration in water or warm water has various effects on the human body and agricultural products, and certain demonstration examples have been published. A carbonated spring (“carbon dioxide spring”) hot spring has been known as a familiar example since it has been effective in relieving fatigue. It is said that the effects of carbonic acid components on the body can be expected to permeate through the skin, promote blood circulation, discharge waste products, eliminate swelling, and improve fatigue recovery by drinking, and improve diabetes, gout, and anemia. ing.

  Furthermore, even if it is used as hydroponics water, soil washing water, or agricultural water, growth of crops is promoted, and when used as washing water for poultry houses and cowsheds, it is not only for animals but also for workers. Studies have been published that improve hygiene.

  Such a carbonated water generator that can be expected to be effective in various fields has been developed and proposed.

  For example, as a method and apparatus for dissolving carbonic acid in water using a mechanical device, Japanese Patent Application Laid-Open No. 2001-293344, “Carbonated Water Production Apparatus and Carbonated Water Production Method” (Patent Document 1) discloses carbon dioxide from a carbon dioxide gas cylinder. Disclosed is a method for dissolving a gas in water using a membrane-type carbon dioxide dissolver such as a hollow fiber membrane (a method for dissolving carbon dioxide by a membrane).

Japanese Patent Laying-Open No. 2009-195812 “Carbonated water production apparatus” (Patent Document 3) discloses an apparatus in which water injected with carbon dioxide gas is pressurized and pressurized to a pressurizing unit to dissolve the carbon dioxide gas in water.

An apparatus using a carbon dioxide dissolver that circulates a path is disclosed.

  Furthermore, as a method and an apparatus for dissolving carbonic acid in water using an electric apparatus, for example, Japanese Patent Application Laid-Open No. 08-196456, “Bath Water Supply Device Dissolving Carbon Dioxide” (Patent Document 5) There is disclosure by Kaihei 08-252192 “Bath hot water supply apparatus” (Patent Document 6). These include electrolysis of water using an electrode for electrolysis composed of at least an anode and a cathode using a carbonaceous electrode, thereby generating carbon dioxide gas in the carbonaceous electrode and dissolving it in water (carbon Generation and dissolution of carbon gas by electrolysis of water using a porous electrode).

  However, the method for dissolving carbon dioxide with a membrane disclosed in Japanese Patent Application Laid-Open No. 2001-293344 (Patent Document 1) has a problem that the membrane is clogged due to generation of scale and / or bacteria, and the carbon dioxide cannot be dissolved. . In addition, the method for dissolving carbon dioxide gas using fine bubbles disclosed in Japanese Patent Application Laid-Open No. 2004-305286 (Patent Document 2) has a problem that a large apparatus is required and the production cost of carbon dioxide gas is high. In addition, the disclosure of Japanese Patent Application Laid-Open No. 2009-195812 (Patent Document 3) needs to include a pressure dissolving part and a pressure reducing part that are dissolved in water by pressurization, and there are many components and the control becomes complicated. There was a problem that was not suitable for home use. Further, the disclosure of Japanese Patent Application Laid-Open No. 2008-212495 (Patent Document 4) has a problem that the production capacity of the carbon dioxide gas dissolving part increases because the pipe length becomes longer, the ability to generate carbonated springs decreases, and the internal structure is complicated. was there.

  Further, carbonated water is produced by the generation and dissolution of carbon gas by electrolysis of water using the carbonaceous electrode disclosed in Japanese Patent Application Laid-Open No. 08-196456 (Patent Document 5) and Japanese Patent Application Laid-Open No. 08-252192 (Patent Document 6). However, it is difficult to produce high-concentration carbonated water suitable for a carbon bath.

  Therefore, the present invention solves the above-described problems, and uses a gas dissolver in which the mixing channel length for performing gas dissolution is short and the production capacity of carbonated water does not decrease even with a simple structure, and the same. An object is to provide a carbonated water generator.

The gas dissolver according to the present invention has a flat partition plate in which a concave portion or a convex portion is formed on one or both surfaces, and the partition plate is disposed facing each other with a predetermined separation distance, and the periphery of the partition plate is hermetically sealed. A gas-liquid mixing zone formed by sealing to form a partition space and a plurality of the gas-liquid mixing zones are overlapped to form a multilayer structure, and each of these layers penetrates each other and the multilayer gas-liquid mixing is performed. It is characterized by comprising a fluid inflow port and an outflow port disposed at spaced positions across the area .

  According to the present invention, the flow flowing through the gas-liquid mixing zone partitioned by the partition plate facing with a predetermined separation distance in which the concave portion or the convex portion (hereinafter referred to as “concave portion”) is formed collides with or interferes with the concave and convex portion. As a result, a turbulent state is formed and the dissolution of the gas in water can be promoted. The predetermined separation distance is set such that the flow particles (fluid particles) can reciprocate a plurality of times between the partition plates from the inlet to the outlet. That is, it is set in consideration of various factors such as the flow velocity, the protruding height of the concavo-convex portion, the motion behavior of particles exhibiting a turbulent state, the stirring state, the area of the partition plate, and the viscosity resistance of water. For example, if the area of the partition plate can be set wide from 1 mm to 3 mm, it may be set from 3 mm to 10 mm. The positional relationship between the inlet and the outlet is set so as to be the farthest path in the gas-liquid mixing area. In addition, when the direction change board for bypassing a flow is provided in a gas-liquid mixing area | region, it arrange | positions considering this.

Moreover, the structure which made the gas-liquid mixing area | region the multilayer structure can reduce in size, without reducing the function of a gas dissolver, and can raise the freedom degree of installation more. That is, if the volume of the gas-liquid mixing zone is wide, the solubility of the gas will increase accordingly, but in the single-layer gas-liquid mixing zone formed only by the facing of the two partition plates, a wide occupied area is obtained. It becomes necessary and lacks compactness (space saving property) and installation property. For this reason, a multi-layered structure in which a large number of the bubble mixing regions are laminated to achieve a reduction in size without impairing the dissolution function.

  The gas dissolver of the invention according to claim 2 has a positional relationship in which the convex and concave portions form a ridge shape or a groove shape, and an extension direction thereof and a streamline direction flowing through the gas-liquid mixing region intersect obliquely. It is characterized by this.

  According to the present invention, since the uneven portion is formed in a continuous shape and is arranged so as to obstruct the flow, it does not follow the shortest path from the inflow port to the outflow port in the direction along the ridge or groove of the uneven portion. This leads to a longer residence time in the gas-liquid mixing zone. As a result, the flow particles (water molecules and carbon dioxide bubbles) are further agitated, and the dissolution of carbon dioxide (or carbon dioxide) can be promoted.

In the gas dissolver of the invention according to claim 3, the ridge-like or groove-like convex part or concave part is repeatedly formed in parallel and at equal intervals, and the repetition period of the concave-convex parts facing each other is the same or The period is different.

  According to the present invention, the flow particles move up and down along the concavities and convexities facing each other, and stirring and mixing are promoted. And when the period is different, more complicated behavior is induced, and the mixing property and the stirring property can be further improved.

Furthermore, the gas dissolver of the invention according to claim 4 is characterized in that the facing arrangement of the partition plates in which the concavo-convex portions are formed with the same period is an arrangement with the same period or an arrangement with a half-cycle deviation. It is what.

  According to this invention, when the repeated periods of the concavities and convexities facing each other are arranged so as to coincide with each other, the vertical movement of the (wave-like) flow particles along this can be made more active and the mixing property and the stirring property are improved. be able to. In addition, facing arrangement in a state shifted by a half cycle, i.e., when the convex part and the concave part are arranged to face each other, an expansion space and a narrow space are formed in the formed space. A compression force and an expansion force can be repeatedly applied. As a result, friction between particles and particle splitting are induced, so that the gas can be further dissolved into the liquid, that is, gas-liquid water in which carbon dioxide is dissolved at a high concentration can be generated.

According to a fifth aspect of the present invention, there is provided a carbonated water generating device, wherein water and carbon dioxide gas (CO2) are separately or merged into a gas dissolver having the above-described configurations and a gas-liquid mixing zone of the gas dissolver. An injection pipe connected to the inflow port for supplying from the outside and an outflow pipe connected to the outflow port for supplying carbonated water generated by the gas dissolver to the outside. .

  According to the present invention, carbon dioxide gas can be efficiently dissolved with only a water pressure and a supply pressure of carbon dioxide gas with a simple structure and without applying external energy such as pressurization or electricity.

In addition, the carbonated water generation device may use heated water instead of room temperature water as water (medium) that is injected into the carbonated water generation device specified above to melt the carbon dioxide gas .

  According to the present invention, carbon dioxide gas can be more efficiently dissolved in water. For example, by appropriately setting the temperature of water, the generated carbonated water can be used as it is as bathing water or at a high temperature. Can be used as hot water for bath water. It can also be used as effective high-temperature sterilizing water or high-temperature disinfecting water.

  According to the present invention of each configuration described above, the gas-liquid mixed with the gas and the medium to be dissolved (water) passes through the gas-liquid mixing area in the narrow space formed by the facing of the partition plate having a predetermined area, Since it reaches from the inflow port to the outflow port, a turbulent state is formed between the planning plates, and the particles are further agitated, so that the degree of dissolution of the soluble gas (such as carbon dioxide) in the liquid can be increased.

  In addition, the gas can be efficiently dissolved in a space-saving manner by making the gas-liquid mixing zone multi-layered.

  Further, the carbonated water generation apparatus using the gas dissolver having the above-described configuration is a carbon dioxide supply means (for example, a gas cylinder filled with carbon dioxide (hereinafter referred to as a gas cylinder filled with carbon dioxide) that can adjust the supply pressure to the inlet of the tap water and the gas dissolver. , "CO2 gas bottle"), it can be easily connected to the pipes of tap water and hot water supply facilities in general households. Only the supply pressure (or water pressure in the case of water supply use) and the gas pressure from the carbon dioxide cylinder do not require additional external energy (for example, additional pressure from the compressor or additional power from an external power source). As a result, it is possible to obtain a carbonated water that is simple, easy and continuous, and that is easy to control and safe, thereby reducing the installation cost of the apparatus and the maintenance cost for maintenance management. Door can be.

It is the schematic which shows the Example (henceforth "this Example apparatus") of the carbonated water production | generation apparatus which concerns on this invention. It is a perspective view which shows the example (henceforth "this example dissolver") of the gas dissolver based on this invention used for this apparatus Example by a partially notched cross section. The cross section of a present Example dissolver is shown, (A) is a cut end view in the central longitudinal direction of the dissolver, and (B) is a partially enlarged view showing a part of (A) in an enlarged manner. .

It is the schematic which shows schematic structure of the specific usage example of a present Example apparatus.

  Next, an example of a specific embodiment of a gas dissolver according to the present invention and a carbonated water generation apparatus using the gas dissolver will be described in detail with reference to the drawings.

  1 and 5 are schematic views showing an embodiment of the present apparatus. The carbonated water generator 1 is connected to an inlet 21 of a gas dissolver 2 which is a main component, and a water injection pipe 3a serving as an inflow pipe 3 for supplying water or hot water from a tap water or a water heater, and an outlet. 22 is connected to an outflow pipe 4 piped to an external device 5 (a bathtub 51, a shower head 52, a faucet 53, or the like). In addition, in order to supply carbon dioxide gas from the carbon dioxide gas cylinder 6 to the vicinity of the inlet 21 to the inlet pipe 3, gas supply as the inlet pipe 3 via the T-shaped joint 3c (commonly called “cheese”) and the regulating valve 3d. The pipe 3b is connected.

  With this configuration, the carbon dioxide gas supplied from the carbon dioxide gas cylinder 6 and the water or hot water flowing through the water injection pipe 3 are merged by the T-shaped joint 3 c and introduced into the gas dissolver 2. And, by the action of the partition plate 23 constituting the gas-liquid mixing zone 7 which will be described later, the carbon dioxide gas dissolves in water and becomes carbonated water and flows out from the outlet 22 and passes through the connected outlet pipe 4 to the outside. It is supplied to the faucet 53 as the bathtub 51 and the shower head 52 of the equipment 5 and further as disinfecting water or cleaning water.

  In the present embodiment apparatus, the supply pressure (water pressure) from the water injection pipe 3a as the water inflow pipe 3 is the water supply pressure or hot water supply pressure from the existing public water supply or individual hot water supply equipment, for example, 0.05 to 0.5 Mpa. It is used by adjusting appropriately within the range. Further, the gas pressure from the carbon dioxide gas cylinder 6 is appropriately adjusted within the range of 0.15 to 0.4 Mpa by the adjusting valve 3d.

  In addition, it can be generated easily and easily in a short time without requiring electric power or dynamic pressure to be additionally supplied from the outside using only water pressure or hot water supply pressure and gas supply pressure as an energy source. In addition, because the entire structure is compact (volume saving), if only a carbon dioxide gas cylinder is procured and installed, carbonated water, which is said to have various human effects and effects, can be used in ordinary households. It can be used easily and easily.

  Next, the gas dissolver which is a main element for carbonated water generation will be described with reference to FIGS. The gas dissolver 2 is formed by partitioning plate plates 23 (mainly made of metal or resin) having a predetermined area and facing each other in parallel with a predetermined separation distance. In this embodiment, the separation distance is set to about 1 mm to 5 mm, for example. This is appropriately set according to the flow rate of water and carbon dioxide to be injected, the flow rate, the distance between the flow paths, and the specifications of the desired dissolved state. Furthermore, the gas-liquid mixing zone 7 is formed by sealing the air gaps 24 around the partition plates 23 and 23 facing each other by welding or by interposing another member therebetween.

  In the vicinity of both ends of the gas-liquid mixing region 7 or at a position where the flow channel faces, an inlet 21 (single in the drawing) that connects the inflow pipe 3 through an appropriate joint (elbow, swivel, etc.). And the outflow port 22 for connecting the outflow pipe 4 to each other. As a position where the flow paths face each other, a diverting plate (not shown) for forming a detour flow path (for example, a U-shaped flow path, a W-shaped flow path, etc.) inside the gas-liquid mixing zone 7 ) Or the like is preferably provided with the farthest possible opposing distance of the gas-liquid mixing region 7. In addition, when the U-shaped detour flow path is formed in the gas-liquid mixing area 7, the inlet 21 and the outlet 22 are adjacent to each other.

  Further, an uneven portion 23 a is formed on the surface of the partition plate 23 that partitions the gas melting region 7. The concavo-convex portion 23a is formed by repeating a continuous ridge shape (or ridge shape) and groove shape in parallel at regular intervals. It has a so-called striped (or corrugated) appearance. Further, the extending direction (formation direction) of the continuous ridges and grooves is formed so as to obliquely intersect the line segment connecting the inflow port 21 and the outflow port 22. This crossing angle is appropriate. As a result, the flow is disturbed by the concavo-convex portion 23a and becomes a turbulent state, and the flow particles (water particles and carbon dioxide gas bubbles) entering from the inlet 21 are disturbed to promote stirring and mixing, and the outlet 22 will be reached. Further, the obstruction of this flow has an effect of promoting the dissolution of carbon dioxide gas in water by lengthening the residence time in the gas-liquid mixing zone 7 and extending the stirring time. In this process, carbon dioxide gas dissolves in water and is in an unstable state, but hydrogen carbonate ions HCO3− and hydrogen ions H + are generated in water. It is said that various effects and effects can be expected when used as drinking water or as bath water depending on the abundance ratio of these ions.

  Further, in the present embodiment shown in the figure, the gas-liquid mixing zone 7 is formed in multiple layers as specified in claim 4. That is, a plurality of gas-liquid mixing regions 7 formed by separating the two partition plates 23 and 23 from each other are overlapped to form a multilayer structure. In the case of this multi-layer structure, the inlet 21 and the outlet 22 are formed so as to penetrate each layer, and the particles (water particles and carbon dioxide gas bubbles) of the flowed in flow through each layer evenly. The configuration is taken into consideration. Although illustration is omitted, for example, the opening diameter of the penetrating inlet 21 is increased as the distance from the connecting portion of the inflow pipe 3 is increased, or a current-transforming plate or a partial shielding plate is provided in the inlet 21. You may do it.

  Each of the partition plates 23, 23,... Arranged in multiple layers so as to overlap each other with a predetermined interval (this interval or different intervals) is repeatedly formed (repeatedly formed) at regular intervals as described above. Above, it is formed in a so-called striped pattern or wave pattern. Further, the partition plates 23, 23,... Repeatedly formed in such a pattern may be formed with the same period or different periods, and the facing arrangement is performed by matching the period of the concavo-convex part 23a. Alternatively, they may be arranged in a shifted state. In the embodiment shown in FIG. 3, the partition plates 23 in which the concave and convex portions 23a are formed in the same cycle are arranged facing each other with a half cycle shift. In other words, it is an arrangement in which the convex portions 23ax and the concave portions 23ay face each other. By arranging in this way, an expansion space 7 a and a narrow space 7 b that are periodically repeated are formed in the space of the gas-liquid mixing region 7.

  By repeating expansion and narrowing in this way, compressive force and expansion force are periodically added to the flow particles, thereby inducing friction between particles and particle splitting. Thereby, the melt | dissolution to the liquid (water or warm water) of gas (carbon dioxide gas) is accelerated | stimulated, and a high concentration carbon dioxide solution (carbonated water) can be obtained.

  Next, the partition plate 23 is not limited to the above configuration, and may be formed in various uneven shapes as shown in FIG. For example, as shown in (A), two or more (or more) top surfaces may be formed on the projection-like uneven portion 23b, and may be formed in a matrix or randomly with appropriate specifications. Moreover, as shown to (B), it is good also as the line-shaped uneven | corrugated | grooved part 23c which interrupted the continuation of the ridge or the groove | channel. This may promote the flow. In particular, when the separation distance of the partition plate 23 is narrowed, it is effective to secure a predetermined flow rate. Furthermore, as shown in (C), when the parallel repeated formation of the ridge-like or groove-like uneven part is arranged obliquely intersecting with the flow direction, the longitudinal center part (or a plurality of longitudinal parts) of the partition plate 23 The direction may be changed at the direction line portion. You may form in a so-called arrow feather-like pattern on the external appearance.

  In addition, the combination at the time of multilayering of the partition plates 23 is appropriately determined in consideration of the shape of the uneven portion 23 and the separation distance in each layer in consideration of the area of each partition plate, the pressure of the influent, the temperature, or the required solubility. Is to be selected.

[Verification data]
Next, the verification data which tested the productivity state of carbonated water using the said Example apparatus is shown below. Tables 1 to 3 show the solubility and carbon dioxide concentration when the temperature of the influent water is changed using three patterns of the influent water amount and water pressure, and the carbon dioxide gas flow rate and gas pressure. 4 shows the solubility and carbon dioxide concentration when the flow rate of carbon dioxide gas is changed at a constant gas pressure with the amount and temperature of the influent water being constant.

  The present invention relates to a gas dissolver for dissolving carbon dioxide (CO2) in water (or hot water) at a high concentration, and a carbonated water generation apparatus using the same.

  In recent years, it has been studied that carbonated water in which carbon dioxide gas is dissolved at a high concentration in water or warm water has various effects on the human body and agricultural products, and certain demonstration examples have been published. A carbonated spring (“carbon dioxide spring”) hot spring has been known as a familiar example since it has been effective in relieving fatigue. It is said that the effects of carbonic acid components on the body can be expected to permeate through the skin, promote blood circulation, discharge waste products, eliminate swelling, and improve fatigue recovery by drinking, and improve diabetes, gout, and anemia. ing.

  Furthermore, even if it is used as hydroponics water, soil washing water, or agricultural water, growth of crops is promoted, and when used as washing water for poultry houses and cowsheds, it is not only for animals but also for workers. Studies have been published that improve hygiene.

  Such a carbonated water generator that can be expected to be effective in various fields has been developed and proposed.

  For example, as a method and apparatus for dissolving carbonic acid in water using a mechanical device, Japanese Patent Application Laid-Open No. 2001-293344, “Carbonated Water Production Apparatus and Carbonated Water Production Method” (Patent Document 1) discloses carbon dioxide from a carbon dioxide gas cylinder. Disclosed is a method for dissolving a gas in water using a membrane-type carbon dioxide dissolver such as a hollow fiber membrane (a method for dissolving carbon dioxide by a membrane). Japanese Patent Application Laid-Open No. 2004-305286, “Method and Apparatus for Dissolving Carbon Dioxide Gas” (Patent Document 2) discloses a method for dissolving carbon dioxide gas from a carbon dioxide gas cylinder as fine bubbles using an injector (dissolving carbon dioxide gas by fine bubbles). Dissolution method) is disclosed. Japanese Patent Laying-Open No. 2009-195812 “Carbonated water production apparatus” (Patent Document 3) discloses an apparatus in which water injected with carbon dioxide gas is pressurized and pressurized to a pressurizing unit to dissolve the carbon dioxide gas in water. Japanese Patent Application Laid-Open No. 2008-212495, “Carbonated Spring Generation Device” (Patent Document 4) discloses a tube in which carbonated water is injected into water and a bellows-like uneven portion is formed on the inner diameter side and wound in a coil shape. An apparatus using a carbon dioxide dissolver that circulates a path is disclosed.

  Furthermore, as a method and an apparatus for dissolving carbonic acid in water using an electric apparatus, for example, Japanese Patent Application Laid-Open No. 08-196456, “Bath Water Supply Device Dissolving Carbon Dioxide” (Patent Document 5) There is disclosure by Kaihei 08-252192 “Bath hot water supply apparatus” (Patent Document 6). These include electrolysis of water using an electrode for electrolysis composed of at least an anode and a cathode using a carbonaceous electrode, thereby generating carbon dioxide gas in the carbonaceous electrode and dissolving it in water (carbon Generation and dissolution of carbon gas by electrolysis of water using a porous electrode).

JP 2001-293344 A JP 2004-305286 A JP 2009-195812 A JP 2008-212495 A Japanese Patent Laid-Open No. 08-196456 Japanese Patent Laid-Open No. 08-252192

  However, the method for dissolving carbon dioxide with a membrane disclosed in Japanese Patent Application Laid-Open No. 2001-293344 (Patent Document 1) has a problem that the membrane is clogged due to generation of scale and / or bacteria, and the carbon dioxide cannot be dissolved. . In addition, the method for dissolving carbon dioxide gas using fine bubbles disclosed in Japanese Patent Application Laid-Open No. 2004-305286 (Patent Document 2) has a problem that a large apparatus is required and the production cost of carbon dioxide gas is high. In addition, the disclosure of Japanese Patent Application Laid-Open No. 2009-195812 (Patent Document 3) needs to include a pressure dissolving part and a pressure reducing part that are dissolved in water by pressurization, and there are many components and the control becomes complicated. There was a problem that was not suitable for home use. Further, the disclosure of Japanese Patent Application Laid-Open No. 2008-212495 (Patent Document 4) has a problem that the production capacity of the carbon dioxide gas dissolving part increases because the pipe length becomes longer, the ability to generate carbonated springs decreases, and the internal structure is complicated. was there.

  Further, carbonated water is produced by the generation and dissolution of carbon gas by electrolysis of water using the carbonaceous electrode disclosed in Japanese Patent Application Laid-Open No. 08-196456 (Patent Document 5) and Japanese Patent Application Laid-Open No. 08-252192 (Patent Document 6). However, it is difficult to produce high-concentration carbonated water suitable for a carbon bath.

Therefore, the present application solves the above-described problems , has a short length of a mixing flow path for gas dissolution, and a gas dissolver in which the ability to generate carbonated water does not decrease even with a simple structure, and a carbonate using the same An object is to provide a water generator.

The gas dissolver of the invention according to the present application (hereinafter referred to as “the present invention”) includes a flat partition plate formed repeatedly on a surface in parallel with a groove-like convex portion or a ridge-like convex portion at equal intervals, and the partition plate Are arranged with a predetermined separation distance so that the concave portion or the convex portion face each other, and the periphery of the partition plate is hermetically sealed to form a partition space, and the gas-liquid mixing region And a fluid inlet / outlet of fluid arranged in a separated position through each of the gas / liquid mixing zones of each layer and sandwiching the gas / liquid mixing zone of each layer. And the extension direction of the groove-like convex portion or the ridge-like convex portion is formed so as to obliquely intersect the line segment connecting the inlet and the outlet. It is.

  According to the present invention, the flow flowing through the gas-liquid mixing zone partitioned by the partition plate facing with a predetermined separation distance formed with the concave portion or the convex portion (hereinafter referred to as “concave portion”) collides with the concave portion or the convex portion. When disturbed, a turbulent state is formed, which can promote the dissolution of the gas in water. The predetermined separation distance is set such that the flow particles (fluid particles) can reciprocate a plurality of times between the partition plates from the inlet to the outlet. That is, it is set in consideration of various factors such as the flow velocity, the protruding height of the concavo-convex portion, the motion behavior of particles exhibiting a turbulent state, the stirring state, the area of the partition plate, and the viscosity resistance of water. For example, if the area of the partition plate can be set wide from 1 mm to 3 mm, it may be set from 3 mm to 10 mm. The positional relationship between the inlet and the outlet is set so as to be the farthest path in the gas-liquid mixing area. In addition, when the direction change board for bypassing a flow is provided in a gas-liquid mixing area | region, it arrange | positions considering this.

Moreover, the structure which made the gas-liquid mixing area | region the multilayer structure can reduce in size, without reducing the function of a gas dissolver, and can raise the freedom degree of installation more. That is, if the volume of the gas-liquid mixing zone is wide, the solubility of the gas will increase accordingly, but in the single-layer gas-liquid mixing zone formed only by the facing of the two partition plates, a wide occupied area is obtained. It becomes necessary and lacks compactness (space saving property) and installation property. For this reason, a multi-layered structure in which a large number of the bubble mixing regions are laminated to achieve a reduction in size without impairing the dissolution function.

Furthermore, in the gas dissolver according to the invention, the formation extension direction of the groove-shaped convex portion or the ridge-shaped convex portion is a positional relationship in which the line segment connecting the inflow port and the outflow port intersects obliquely. It is what.

By adding the configuration of the uneven portion in this way, the present invention makes the uneven portion a continuous state and is arranged so as to obstruct the flow, so the shortest path (almost straight line) from the inlet to the outlet It is guided in the direction along the ridge or groove of the concavo-convex portion without following, and thereby the residence time in the gas-liquid mixing zone can be lengthened. As a result, the flow particles (water molecules and carbon dioxide bubbles) are further agitated, and the dissolution of carbon dioxide (or carbon dioxide) can be promoted.

In the gas dissolver according to the present invention, the ridge-shaped or groove-shaped convex portions or concave portions are formed repeatedly in parallel and at equal intervals, and the repetition cycle of the facing concave-convex portions is the same or different. It is characterized by being.

As a result, the flow particles move up and down along the concavities and convexities facing each other to promote stirring and mixing. And when the period is different, more complicated behavior is induced, and the mixing property and the stirring property can be further improved.

Furthermore, in the case where the partition plates having the uneven portions formed in the same cycle are arranged facing each other, they may be arranged in a positional relationship with the same period or in a positional relationship shifted by a half cycle .

In this way, when arranged in a positional relationship in which the repetition periods of the concavities and convexities facing each other are made to coincide, the (wave-like) flow particles can move more and more vertically along this, and the mixing property and stirring property can be improved. Can be increased. In addition, when facing in a positional relationship shifted by a half cycle, in other words, in a case where the convex portion and the concave portion are arranged to face each other in a positional relationship facing each other, the expansion space and the narrow space are formed in the formed space. Therefore, compressive force and expansion force can be repeatedly applied to the flow particles. As a result, the splitting of these particles is more actively induced than the friction and collision between the liquid particles and the gas particles, and the dissolution of the gas into the liquid can be further promoted. Thereby, gas-liquid water in which carbon dioxide gas is dissolved at a high concentration can be generated.

According to a fourth aspect of the present invention, there is provided a carbonated water generating apparatus, wherein water and carbon dioxide (CO2) are separately or merged into a gas dissolver having the above-described configurations and a gas-liquid mixing zone of the gas dissolver. An injection pipe connected to the inflow port for supplying from the outside and an outflow pipe connected to the outflow port for supplying carbonated water generated by the gas dissolver to the outside. .

  According to the present invention, carbon dioxide gas can be efficiently dissolved with only a water pressure and a supply pressure of carbon dioxide gas with a simple structure and without applying external energy such as pressurization or electricity.

In addition, the carbonated water generation device may use heated water instead of room temperature water as water (medium) that is injected into the carbonated water generation device specified above to melt the carbon dioxide gas .

  According to the present invention, carbon dioxide gas can be more efficiently dissolved in water. For example, by appropriately setting the temperature of water, the generated carbonated water can be used as it is as bathing water or at a high temperature. Can be used as hot water for bath water. It can also be used as effective high-temperature sterilizing water or high-temperature disinfecting water.

  According to the present invention of each configuration described above, the gas-liquid mixed with the gas and the medium to be dissolved (water) passes through the gas-liquid mixing area in the narrow space formed by the facing of the partition plate having a predetermined area, Since it reaches from the inflow port to the outflow port, a turbulent state is formed between the planning plates, and the particles are further agitated, so that the degree of dissolution of the soluble gas (such as carbon dioxide) in the liquid can be increased.

  In addition, the gas can be efficiently dissolved in a space-saving manner by making the gas-liquid mixing zone multi-layered.

  Further, the carbonated water generation apparatus using the gas dissolver having the above-described configuration is a carbon dioxide supply means (for example, a gas cylinder filled with carbon dioxide (hereinafter referred to as a gas cylinder filled with carbon dioxide) that can adjust the supply pressure to the inlet of the tap water and the gas dissolver. , "CO2 gas bottle"), it can be easily connected to the pipes of tap water and hot water supply facilities in general households. Only the supply pressure (or water pressure in the case of water supply use) and the gas pressure from the carbon dioxide cylinder do not require additional external energy (for example, additional pressure from the compressor or additional power from an external power source). As a result, it is possible to obtain a carbonated water that is simple, easy and continuous, and that is easy to control and safe, thereby reducing the installation cost of the apparatus and the maintenance cost for maintenance management. Door can be.

  Next, an example of a specific embodiment of a gas dissolver according to the present invention and a carbonated water generation apparatus using the gas dissolver will be described in detail with reference to the drawings.

  1 and 5 are schematic views showing an embodiment of the present apparatus. The carbonated water generator 1 is connected to an inlet 21 of a gas dissolver 2 which is a main component, and a water injection pipe 3a serving as an inflow pipe 3 for supplying water or hot water from a tap water or a water heater, and an outlet. 22 is connected to an outflow pipe 4 piped to an external device 5 (a bathtub 51, a shower head 52, a faucet 53, or the like). In addition, in order to supply carbon dioxide gas from the carbon dioxide gas cylinder 6 to the vicinity of the inlet 21 to the inlet pipe 3, gas supply as the inlet pipe 3 via the T-shaped joint 3c (commonly called “cheese”) and the regulating valve 3d. The pipe 3b is connected.

  With this configuration, the carbon dioxide gas supplied from the carbon dioxide gas cylinder 6 and the water or hot water flowing through the water injection pipe 3 are merged by the T-shaped joint 3 c and introduced into the gas dissolver 2. And, by the action of the partition plate 23 constituting the gas-liquid mixing zone 7 which will be described later, the carbon dioxide gas dissolves in water and becomes carbonated water and flows out from the outlet 22 and passes through the connected outlet pipe 4 to the outside. It is supplied to the faucet 53 as the bathtub 51 and the shower head 52 of the equipment 5 and further as disinfecting water or cleaning water.

  In the present embodiment apparatus, the supply pressure (water pressure) from the water injection pipe 3a as the water inflow pipe 3 is the water supply pressure or hot water supply pressure from the existing public water supply or individual hot water supply equipment, for example, 0.05 to 0.5 Mpa. It is used by adjusting appropriately within the range. Further, the gas pressure from the carbon dioxide gas cylinder 6 is appropriately adjusted within the range of 0.15 to 0.4 Mpa by the adjusting valve 3d.

  In addition, it can be generated easily and easily in a short time without requiring electric power or dynamic pressure to be additionally supplied from the outside using only water pressure or hot water supply pressure and gas supply pressure as an energy source. In addition, because the entire structure is compact (volume saving), if only a carbon dioxide gas cylinder is procured and installed, carbonated water, which is said to have various human effects and effects, can be used in ordinary households. It can be used easily and easily.

  Next, the gas dissolver which is a main element for carbonated water generation will be described with reference to FIGS. The gas dissolver 2 is formed by partitioning plate plates 23 (mainly made of metal or resin) having a predetermined area and facing each other in parallel with a predetermined separation distance. In this embodiment, the separation distance is set to about 1 mm to 5 mm, for example. This is appropriately set according to the flow rate of water and carbon dioxide to be injected, the flow rate, the distance between the flow paths, and the specifications of the desired dissolved state. Furthermore, the gas-liquid mixing zone 7 is formed by sealing the air gaps 24 around the partition plates 23 and 23 facing each other by welding or by interposing another member therebetween.

  In the vicinity of both ends of the gas-liquid mixing region 7 or at a position where the flow channel faces, an inlet 21 (single in the drawing) that connects the inflow pipe 3 through an appropriate joint (elbow, swivel, etc.). And the outflow port 22 for connecting the outflow pipe 4 to each other. As a position where the flow paths face each other, a diverting plate (not shown) for forming a detour flow path (for example, a U-shaped flow path, a W-shaped flow path, etc.) inside the gas-liquid mixing zone 7 ) Or the like is preferably provided with the farthest possible opposing distance of the gas-liquid mixing region 7. In addition, when the U-shaped detour flow path is formed in the gas-liquid mixing area 7, the inlet 21 and the outlet 22 are adjacent to each other.

  Further, an uneven portion 23 a is formed on the surface of the partition plate 23 that partitions the gas melting region 7. The concavo-convex portion 23a is formed by repeating a continuous ridge shape (or ridge shape) and groove shape in parallel at regular intervals. It has a so-called striped (or corrugated) appearance. Further, the extending direction (formation direction) of the continuous ridges and grooves is formed so as to obliquely intersect the line segment connecting the inflow port 21 and the outflow port 22. This crossing angle is appropriate. As a result, the flow is disturbed by the concavo-convex portion 23a and becomes a turbulent state, and the flow particles (water particles and carbon dioxide gas bubbles) entering from the inflow port 21 are disturbed to promote stirring and mixing, and the outflow port 22 will be reached. Further, the obstruction of this flow has an effect of promoting the dissolution of carbon dioxide gas in water by lengthening the residence time in the gas-liquid mixing zone 7 and extending the stirring time. In this process, carbon dioxide gas dissolves in water and is in an unstable state, but hydrogen carbonate ions HCO3− and hydrogen ions H + are generated in water. It is said that various effects and effects can be expected when used as drinking water or as bath water depending on the abundance ratio of these ions.

  Further, in the present embodiment shown in the figure, the gas-liquid mixing zone 7 is formed in multiple layers as specified in claim 4. That is, a plurality of gas-liquid mixing regions 7 formed by separating the two partition plates 23 and 23 from each other are overlapped to form a multilayer structure. In the case of this multi-layer structure, the inlet 21 and the outlet 22 are formed so as to penetrate each layer, and the particles (water particles and carbon dioxide gas bubbles) of the flowed in flow through each layer evenly. The configuration is taken into consideration. Although illustration is omitted, for example, the opening diameter of the penetrating inlet 21 is increased as the distance from the connecting portion of the inflow pipe 3 is increased, or a current-transforming plate or a partial shielding plate is provided in the inlet 21. You may do it.

  Each of the partition plates 23, 23,... Arranged in multiple layers so as to overlap each other with a predetermined interval (this interval or different intervals) is repeatedly formed (repeatedly formed) at regular intervals as described above. Above, it is formed in a so-called striped pattern or wave pattern. Further, the partition plates 23, 23,... Repeatedly formed in such a pattern may be formed with the same period or different periods, and the facing arrangement is performed by matching the period of the concavo-convex part 23a. Alternatively, they may be arranged in a shifted state. In the embodiment shown in FIG. 3, the partition plates 23 in which the concave and convex portions 23a are formed in the same cycle are arranged facing each other with a half cycle shift. In other words, it is an arrangement in which the convex portions 23ax and the concave portions 23ay face each other. By arranging in this way, an expansion space 7 a and a narrow space 7 b that are periodically repeated are formed in the space of the gas-liquid mixing region 7.

  By repeating expansion and narrowing in this way, compressive force and expansion force are periodically added to the flow particles, thereby inducing friction between particles and particle splitting. Thereby, the melt | dissolution to the liquid (water or warm water) of gas (carbon dioxide gas) is accelerated | stimulated, and a high concentration carbon dioxide solution (carbonated water) can be obtained.

  Next, the partition plate 23 is not limited to the above configuration, and may be formed in various uneven shapes as shown in FIG. For example, as shown in (A), two or more (or more) top surfaces may be formed on the projection-like uneven portion 23b, and may be formed in a matrix or randomly with appropriate specifications. Moreover, as shown to (B), it is good also as the line-shaped uneven | corrugated | grooved part 23c which interrupted the continuation of the ridge or the groove | channel. This may promote the flow. In particular, when the separation distance of the partition plate 23 is narrowed, it is effective to secure a predetermined flow rate. Furthermore, as shown in (C), when the parallel repeated formation of the ridge-like or groove-like uneven part is arranged obliquely intersecting with the flow direction, the longitudinal center part (or a plurality of longitudinal parts) of the partition plate 23 The direction may be changed at the direction line portion. You may form in a so-called arrow feather-like pattern on the external appearance.

  In addition, the combination at the time of multilayering of the partition plates 23 is appropriately determined in consideration of the shape of the uneven portion 23 and the separation distance in each layer in consideration of the area of each partition plate, the pressure of the influent, the temperature, or the required solubility. Is to be selected.

[Verification data]
Next, the verification data which tested the productivity state of carbonated water using the said Example apparatus is shown below. Tables 1 to 3 show the solubility and carbon dioxide concentration when the temperature of the influent water is changed using three patterns of the influent water amount and water pressure, and the carbon dioxide gas flow rate and gas pressure. 4 shows the solubility and carbon dioxide concentration when the flow rate of carbon dioxide gas is changed at a constant gas pressure with the amount and temperature of the influent water being constant.
