Embodiment 1 FIG.
1 is a schematic diagram showing a configuration of an active oxygen species generating apparatus according to Embodiment 1 of the present invention.
In FIG. 1, 1 is a pipe through which water flows. An arrow A in FIG. 1 indicates the direction of water flowing in the pipe 1. Reference numeral 2 denotes a dissolved oxygen improving means connected to the pipe 1. The dissolved oxygen improving means 2 is disposed on the downstream side of the pipe 1. 3 is a pipe connected to the dissolved oxygen improving means 2. The pipe 3 is arranged on the downstream side of the pipe 1 and the dissolved oxygen improving means 2. That is, the dissolved oxygen improving means 2 is provided between the pipe 1 and the pipe 3. The water flowing inside each of the pipe 1, the dissolved oxygen improving means 2, and the pipe 3 includes, for example, organic matter containing bacteria.

The pipe 3 has a predetermined material (active oxygen species generating material) having an active oxygen species generating ability on the inner wall surface.
As a material having an active oxygen species generating ability, there is a conductive polymer (redox polymer). Specific examples of the conductive polymer include polyaniline, polythiophene, polypyrrole, polyacene and the like. In the pipe 3, for example, a conductive polymer is applied to the inner wall of the base material. As the conductive polymer applied to the base material of the pipe 3, polyaniline that is chemically structurally stable is suitable.

The conductive polymer (redox polymer) is a polymer that reversibly changes to an oxidized state or a reduced state by transfer of electrons. The polymerization of the conductive polymer includes chemical polymerization or electrical polymerization. FIG. 2 is a diagram showing a structural change of polyaniline due to an oxidation-reduction reaction. As shown in FIG. 2, when the polyaniline undergoes a structural change from a reduced form to an oxidized form, it reacts oxygen in water with one electron to produce superoxide (O ₂ ⁻ ), which is a kind of active oxygen. (See Equation 1).
O ₂ + PAn (red) → O ₂ ⁻ + PAn (ox) (1)

  The reaction represented by the above formula 1 is caused by the redox potential between the polyaniline and the reactant. For this reason, when superoxide is produced | generated by reaction shown by Formula 1, gas, such as hydrogen and oxygen, is not produced | generated secondary. Further, when superoxide is generated, it is not necessary to directly energize the active oxygen species generating material (pipe 3).

  The produced superoxide has a short lifetime. However, since polyaniline is provided on the inner wall of the pipe 3, even when the pipe 3 is long, the superoxide can be spread over the entire inner wall of the pipe 3 to suppress the growth of bacteria.

  The structure of polyaniline changes to an oxidized form with the passage of time by the reaction of generating reactive oxygen species (superoxide) shown in Formula 1. In order to return the polyaniline whose structure has changed to the oxidized type to the reduced type, it is desirable to provide the pipe 3 with an electron supply material for supplying electrons to the polyaniline. The electron supply material is made of a substance having a lower oxidation-reduction potential than polyaniline. The electron supply material is disposed in contact with the polyaniline so that electrons can be supplied to the polyaniline.

  Specific examples of the electron supply material include metal materials such as aluminum, titanium, and stainless steel, and materials such as carbon. When the base material of the pipe 3 is composed of an electron supply material, polyaniline may be applied so as to be in contact with the base material. On the other hand, when the base material of the pipe 3 is not composed of an electron supply material, it is necessary to mix the electron supply material with the polyaniline layer (active oxygen species generating material layer). In such a case, the shape of the electron supply material is preferably a shape having a large surface area in contact with polyaniline (for example, a particulate shape).

  By providing the pipe 3 with the electron supply material, it is possible to return the polyaniline that has been changed to the oxidized form by the reactive oxygen species generation reaction to the reduced form, and to stably generate a reversible oxidation-reduction reaction for a long period of time. For this reason, it becomes possible to maintain the antimicrobial effect in the piping 3 stably for a long period of time.

  The above is an explanation when polyaniline is used as the conductive polymer (redox polymer). Even when another conductive polymer is applied to the base material of the pipe 3, the same effect as described above can be expected.

  As shown in Equation 1, the active oxygen species generating material applied to the inner wall of the base material of the pipe 3 generates active oxygen species by directly reacting with dissolved oxygen in water. For this reason, if the dissolved oxygen density | concentration in water is improved (it makes high), an active oxygen species production | generation ability can be improved. The dissolved oxygen improving means 2 is provided for improving the dissolved oxygen concentration in water. The dissolved oxygen improving means 2 has a function of making the dissolved oxygen concentration in water in the pipe 3 higher than the dissolved oxygen concentration in water in the pipe 1. That is, the dissolved oxygen concentration of the water flowing out from the dissolved oxygen improving means 2 is higher than the dissolved oxygen concentration of the water flowing into the dissolved oxygen improving means 2.

Specifically, the dissolved oxygen improving unit 2 includes a microbubble generating unit 4 and a microbubble crushing unit 5 disposed on the upstream side of the pipe 3.
The microbubble generating means 4 is for generating microbubbles in water. The microbubbles generated by the microbubble generating means 4 preferably have a main particle size of less than 1 μm. The microbubbles generated by the microbubble generating means 4 are sent to the downstream side together with water.

  Examples of the microbubble generating means 4 include a swirl method and an ultrasonic irradiation method. In the microbubble generating means 4 adopting the swirling method, the bubbles are miniaturized by the shearing force generated when water and air are swung at high speed, and microbubbles are generated in the water. When the swirling method is adopted, the bubble diameter and the bubble density can be adjusted by providing the intake portion according to the structure inside the pipe. For this reason, the microbubble generating means 4 can generate microbubbles with a simple configuration. In addition, when the turning method is adopted, energy consumption can be suppressed.

  The microbubble crushing means 5 is for crushing the microbubbles generated by the microbubble generating means 4. The microbubble crushing means 5 crushes microbubbles existing in water by, for example, a shock wave using an ultrasonic irradiation method, an underwater discharge method, or the like.

  The microbubble crushing means 5 is arranged on the downstream side of the microbubble generating means 4. The micro-bubbles generated by the micro-bubble generating means 4 are micronized from the bubble state to the molecular level by the micro-bubble crushing means 5 and sent to the downstream side together with water. That is, oxygen that has been crushed by the microbubble crushing means 5 and dissolved in water flows through the pipe 3 disposed on the downstream side of the dissolved oxygen improving means 2. For this reason, high concentration dissolved oxygen water is supplied to the piping 3. Inside the pipe 3, the active oxygen species generating material provided on the inner wall of the pipe 3 reacts with oxygen dissolved in water to generate active oxygen species on the surface of the inner wall of the pipe 3.

  Reactive oxygen species have strong oxidizing power. For this reason, when reactive oxygen species react with microorganisms such as bacteria mixed in water, proteins on the surface of the microorganism are damaged, and the microorganism stops its life activity. As a result, on the inner wall surface of the pipe 3, the propagation of bacteria is suppressed and high hygiene can be maintained.

  The above description relates to the basic operation of the present active oxygen species generator, that is, the operation when water is supplied to the active oxygen species generator and water sequentially flows through the pipe 1, the dissolved oxygen improving means 2, and the pipe 3. It is. If water is supplied to the active oxygen species generating device, high concentration dissolved oxygen water obtained by the function of the dissolved oxygen improving means 2 can be sequentially fed into the pipe 3. On the other hand, when the supply of water to the active oxygen species generating device is stopped, the flow of water in the dissolved oxygen improving means 2 and the pipe 3 is also stopped, so that oxygen dissolved in water cannot be newly fed into the pipe 3. For this reason, after the water supply to the active oxygen species generating device is stopped, the amount of dissolved oxygen in the pipe 3 gradually decreases.

FIG. 3 is a graph showing the transition of dissolved oxygen saturation. FIG. 3 shows the transition of dissolved oxygen saturation when the main particle size of microbubbles is less than 10 ⁻⁶ m and the transition of dissolved oxygen saturation when the main particle size of microbubbles is 10 ⁻⁶ m or more. It shows. Specifically, the initial dissolved oxygen saturation in the water tank was set to the same level, microbubbles were generated in the water tank for 5 minutes, and then the generation of microbubbles was stopped. FIG. 3 shows the result of measuring only the dissolved oxygen saturation rate in such a state.

As shown in FIG. 3, when the main particle size of microbubbles is less than 10 -6 ^m than if the main grain size of the microbubbles is 10 -6 ^m or more, the dissolved oxygen saturation at the time of generation of microbubbles The rate can be increased. Further, when the main particle size of microbubbles is less than 10 -6 ^m than if the main grain size of the microbubbles is 10 -6 ^m or more, even after stopping the generation of microbubbles, dissolved oxygen saturation The rate can be kept high.

From the above results, it is preferable that the microbubbles generated in the microbubble generating means 4 have a main particle size in a predetermined range of 10 ⁻⁶ m or less, for example, 10 ^{−9 to} 10 ⁻⁶ m. With such a configuration, the amount of dissolved oxygen in the pipe 3 is kept high and the ability to generate active oxygen species is maintained for a long time even when water supply to the active oxygen species generating device is stopped. Can do. That is, even after the water supply to the reactive oxygen species generating device is stopped, the propagation of bacteria in the pipe 3 can be suppressed.

In addition, since the order of the molecular size is less than 10 ⁻⁹ m, it is difficult for the microbubble generating unit 4 having the above configuration to generate microbubbles having a main particle size smaller than 10 ⁻⁹ m. As the microbubble generating means 4, those that generate so-called nanobubbles are suitable.

  If it is the active oxygen species production | generation apparatus which has the said structure, the suitable antimicrobial effect by an active oxygen species production | generation material can be anticipated. That is, in the active oxygen species generating device having the above-described configuration, high-concentration dissolved oxygen water can be supplied to the pipe 3, and the growth of bacteria on the inner wall surface of the pipe 3 can be reliably suppressed. Further, when generating the active oxygen species, no other gas is generated as a secondary, and the amount of energy consumption can be greatly reduced.

In the present application, the active oxygen species superoxide _{(O 2} · ^-), hydroxy radicals (· OH), hydrogen peroxide _{(H 2 O} 2), singlet oxygen ⁽¹ _O 2), ozone _{(O 3),} etc. , Oxygen activated by triplet oxygen (O ₂ ), which is molecular oxygen, and related molecules.

  In addition, in the present application, antibacterial is a concept including sterilization, disinfection, sterilization, sterilization, and antibacterial, and refers to suppressing or killing generation, growth, and proliferation of microorganisms and certain substances.

Embodiment 2. FIG.
In this embodiment, an example in which the active oxygen species generating device (the basic configuration thereof) described in Embodiment 1 is applied to a hot water supply device will be described.
FIG. 4 is a diagram showing the configuration of the hot water supply apparatus according to Embodiment 2 of the present invention. In FIG. 4, 6 is a bathtub, 7 is a hot water storage tank for storing hot water supplied as bath water for the bathtub 6, 8 is a water supply valve for supplying tap water to the bathtub 6, 9 is a water supply pipe, and 10 is a reheating pipe. It is.

  The reheating pipe 10 is a pipe for circulating the water in the bathtub 6 at the time of reheating. Both ends of the reheating pipe 10 are open into the bathtub 6. A pump 11 that circulates the water in the bathtub 6 and a heat exchanger 12 that heats the water are incorporated in the reheating pipe 10 in the middle thereof.

  The water supply pipe 9 is a pipe arranged on the upstream side of the reheating pipe 10. One end (downstream end) of the water supply pipe 9 is connected to the reheating pipe 10. The water supply pipe 9 is divided into two in the middle, and the other end (upstream end) is connected to the hot water storage tank 7. . The other end of the water supply pipe 9 is connected to another pipe (not shown) for supplying tap water, and a water supply valve 8 is provided in the middle thereof. The water supply pipe 9 supplies hot water inside the hot water storage tank 7 and tap water to the downstream side by opening the water supply valve 8.

  In the hot water supply apparatus having the above configuration, the dissolved oxygen improving means 2 described in the first embodiment is provided in the middle of the water supply pipe 9. In the dissolved oxygen improving means 2, the microbubble generating means 4 is arranged on the upstream side of the microbubble crushing means 5, and an upstream water supply pipe 9 is provided on the water supply side of the microbubble generating means 4 on the drain side of the microbubble crushing means 5. A downstream water supply pipe 9 is connected to the pipe. That is, in the present embodiment, the water supply pipe 9 and the reheating pipe 10 arranged on the downstream side of the dissolved oxygen improving means 2 constitute the pipe 3 having the active oxygen species generating material on the surface of the inner wall. In FIG. 4, the portion where the active oxygen species generating material is applied is indicated by hatching.

Next, the operation of the hot water supply apparatus will be described.
Hot water boiled in the hot water storage tank 7 (or tap water that has passed through the water supply valve 8) is supplied to the dissolved oxygen improving means 2 through the water supply pipe 9 (on the upstream side). In the dissolved oxygen improving unit 2, the microbubble generating unit 4 generates microbubbles having a main particle size of less than 1 μm, for example, in hot water. Further, the microbubble crushing means 5 crushes the microbubbles generated by the microbubble generating means 4 and micronizes the microbubbles from the bubble state to the molecular level.

  Oxygen that is crushed by the microbubble crushing means 5 and dissolved in the hot water is supplied to the bathtub 6 through the water supply pipe 9 (downstream side) and the reheating pipe 10 together with the hot water. A conductive polymer such as polyaniline is applied to the inner wall of the base material in the water supply pipe 9 and the reheating pipe 10 arranged on the downstream side of the dissolved oxygen improving means 2. For this reason, in the downstream water supply pipe 9 and the reheating pipe 10, the active oxygen species generating material provided on the inner wall surface reacts with the oxygen dissolved in the hot water to generate active oxygen species on the inner wall surface. Can do.

  Reactive oxygen species have strong oxidizing power. For this reason, when reactive oxygen species react with microorganisms such as bacteria mixed in the hot water, proteins on the surface of the microorganisms are damaged, and the microorganisms stop their life activity. As a result, on the inner wall surfaces of the downstream water supply pipe 9 and the follow-up pipe 10, the growth of bacteria is suppressed and high hygiene can be maintained.

Also in this hot water supply apparatus, the microbubbles generated by the microbubble generating means 4 preferably have a main particle size of 10 ^{−9 to} 10 ⁻⁶ m. With such a configuration, even when hot water supply (water supply) from the hot water storage tank 7 (or the water supply valve 8) to the bathtub 6 is stopped, the amount of dissolved oxygen in the water supply pipe 9 and the reheating pipe 10 is high. And the ability to generate active oxygen species can be maintained over a long period of time. That is, the propagation of bacteria in the water supply pipe 9 and the catching pipe 10 can be suppressed for a long time.

FIG. 5 is a diagram showing another configuration of the hot water supply apparatus according to Embodiment 2 of the present invention.
In the hot water supply apparatus shown in FIG. 5, in addition to the structure shown in FIG. The dissolved oxygen improving means 2a has the same configuration as the dissolved oxygen improving means 2. That is, the dissolved oxygen improving unit 2 a includes a microbubble generating unit 4 a having the same function as the microbubble generating unit 4 and a microbubble collapsing unit 5 a having the same function as the microbubble crushing unit 5. The microbubble crushing means 5a is arranged on the downstream side of the microbubble generating means 4a.

  When reheating water (hot water) stored in the bathtub 6, the water in the bathtub 6 is taken into the reheating pipe 10 by the pump 11, heated by the heat exchanger 12, and then returned to the bathtub 6. With the configuration shown in FIG. 5, high-concentration dissolved oxygen water can be generated in the reheating pipe 10 even at the time of reheating, and the growth of bacteria in the reheating pipe 10 can be suppressed.

  Matters not mentioned in the present embodiment have the same configurations as those of the first embodiment. Thereby, also in a water supply apparatus, there can exist an effect similar to Embodiment 1. FIG.

Embodiment 3 FIG.
In this embodiment, an example will be described in which the active oxygen species generating device (the basic configuration thereof) described in Embodiment 1 is applied to an air conditioner.
FIG. 6 is a diagram showing the configuration of the air-conditioning equipment according to Embodiment 3 of the present invention. FIG. 6 shows an air conditioner having a cooling tower 13. As shown in FIG. 6, the cooling tower 13 includes a pump 14, a circulation pipe 15, a heat exchange unit 16, a water storage unit 17, and a fan 18.

  The pump 14 is for circulating water in the cooling tower 13. The water circulated in the cooling tower 13 by the pump 14 is supplied to the heat exchange unit 16 through the circulation pipe 15 in the direction of the arrow shown in FIG. The heat exchange unit 16 performs heat exchange of the water supplied from the circulation pipe 15. The water flowing down from the heat exchange unit 16 is accumulated in the water storage unit 17. The circulation pipe 15 has one end connected to the water storage unit 17 and the other end connected above the heat exchange unit 16. That is, the water stored in the water storage unit 17 is taken into the circulation pipe 15 by the pump 14 and is sent to the heat exchange unit 16 through the circulation pipe 15. The fan 18 is for air-cooling the water flowing down in the heat exchanging unit 16, and constitutes, for example, means for taking outside air into the cooling tower 13.

  In the present embodiment, the heat exchange unit 16 constitutes the dissolved oxygen improving means 2 (the microbubble generating means 4). That is, the water supplied to the heat exchanging unit 16 from the other end of the circulation pipe 15 comes into contact with the air taken into the cooling tower 13 when the heat exchanging unit 16 is dropped, and microbubbles are generated inside. The For this reason, the water flowing down from the heat exchange unit 16 (stored in the water storage unit 17) has a higher dissolved oxygen concentration than the water supplied from the circulation pipe 15 to the heat exchange unit 16.

  When the microbubble crushing means 5 is provided in the cooling tower 13 having the above configuration, the microbubbles crushing means 5 may be configured to crush the microbubbles contained in the water stored in the water storage unit 17.

In this embodiment, in order to have a sterilizing effect on the entire inner wall of the circulation pipe 15, the circulation pipe 15 extends from one end connected to the water storage unit 17 to the other end above the heat exchange unit 16. An active oxygen species generating material is applied to the surface of the inner wall of the substrate. In FIG. 6, a portion where the active oxygen species generating material is applied is indicated by hatching.

  In the air conditioner having the above configuration, the water dripped from the heat exchanging unit 16 and stored in the water storage unit 17 is taken into the circulation pipe 15 when the pump 14 is operated. In the circulation pipe 15, for example, a conductive polymer such as polyaniline is applied to the inner wall of the base material. Therefore, in the circulation pipe 15, the active oxygen species generating material provided on the inner wall surface reacts with oxygen dissolved in water, and active oxygen species can be generated on the inner wall surface.

  Reactive oxygen species have strong oxidizing power. For this reason, when reactive oxygen species react with microorganisms such as bacteria mixed in water, proteins on the surface of the microorganism are damaged, and the microorganism stops its life activity. As a result, on the inner wall surface of the circulation pipe 15, the growth of bacteria is suppressed and high hygiene can be maintained.

Moreover, also in this air conditioner, it is preferable that the microbubbles produced | generated in the heat exchange part 16 (namely, microbubble production | generation means 4) have the main particle size of 10 ^<-9> thru ^| or 10 ^<-6> m. With such a configuration, even when water circulation (that is, the pump 14) is stopped, the amount of dissolved oxygen in the circulation pipe 15 is kept high, and the ability to generate active oxygen species is maintained for a long time. can do. That is, the propagation of bacteria in the circulation pipe 15 can be suppressed for a long time.

  In the present embodiment, the case where the heat exchange unit 16 has the function of the dissolved oxygen improving means 2 (the microbubble generating means 4) has been described. However, the dissolved oxygen improving means 2 is installed in the middle of the circulation pipe 15. May be. For example, the microbubble generating means 4 that employs a swirling method or an ultrasonic irradiation method is installed in the middle of one end of the circulation pipe 15. Further, the microbubble crushing means 5 is installed on the downstream side of the microbubble generating means 4. With such a configuration, the portion arranged on the downstream side of the dissolved oxygen improving means 2 in the one end side of the circulation pipe 15 can be configured as the pipe 3, thereby suppressing the growth of bacteria inside the pipe. be able to. Also at this time, it is preferable to apply the active oxygen species generating material to the entire inner wall of a portion of the circulation pipe 15 disposed downstream of the dissolved oxygen improving means 2.

  Matters not mentioned in the present embodiment have the same configurations as those of the first embodiment. Thereby, also in an air-conditioning apparatus, there can exist an effect similar to Embodiment 1. FIG.

  The active oxygen species generating device shown in Embodiment 1 can be applied to any device provided with a pipe through which water flows, in addition to a hot water supply device and an air conditioner.
