[Technical field to which the invention belongs]

 According to the present invention, an ion generator is installed in the middle of a water channel that returns water to water facilities such as bathtubs, ponds, fountains, pools, water tanks, etc., and the water in the water facilities is sterilized with metal ions generated by the ion generator. It relates to a device for killing alga.

[0002]

[Prior art]

 Conventionally, a metal ion generator having a plurality of metal plates is provided in a water facility such as a bathtub, a pond, a fountain, a pool, a water tank, etc., in the middle of a flow path for returning a predetermined amount of water, and the metal plates are electrolyzed. A sterilizing and algicidal apparatus is known which sterilizes or algae-kills water in the above-mentioned water facility with metal ions, particularly silver ions, copper ions and the like (for example, Japanese Utility Model Application Laid-Open No. 2-66294). issue). The germicidal and algicidal device using this metal ion has many advantages such as excellent germicidal activity and algicidal activity, being inexpensive and easy to use, and has been widely adopted in recent years.

[0003]

[Problems to be solved by the invention]

 However, when the water in the water tank or the like is severely contaminated, the sterilizing power of silver ions and the algicidal power of copper ions are limited, and it takes a long time to sterilize and purify such water. Was. Therefore, it was necessary to add a chlorinated chemical (such as sodium hypochlorite) to the water facility to enhance the bactericidal and algicidal activity by the catalytic action of metal ions. As a result, the cost is increased and the operation is complicated. Furthermore, by adding chlorine-based chemicals to water facilities, the quality of hot spring water changes, the filter circulation system becomes oxidized and corroded, and its life (durability) is shortened. There has been a problem of giving discomfort such as odor, irritation to eyes, skin, nose and throat, and the like.

[0004] When the metal plate in the ion generator is made of only the same type of metal plate, a part of the eluted metal ions returns to the original metal. There was a disadvantage that the efficiency of algicidal power was reduced. That is, for example, when all of the metal plates are copper electrode plates and electrolyzed, the copper ions generated at the anode are attracted to the cathode. At that time, hydrogen gas is generated near the cathode and alkaline Therefore, the charge of the copper ion is lost. As a result, copper ions disappear and instead copper powder precipitates out and adheres to the copper plate of the cathode or precipitates at the bottom of the water bath. Therefore, not only the sterilization effect of the copper ions is reduced, but also problems such as contamination of the copper electrode plate and turbidity of water due to precipitation of copper powder have occurred. This has been the case with other metals used in this type of water disinfection and algicidal devices, such as silver and copper-silver alloys.

[0005] The present invention has been made in view of these drawbacks, and does not use any chlorine-based chemicals that have a harmful effect on the human body and the like, does not deposit metal powder, and is simple. It is an object of the present invention to provide a liquid sterilizing and algicidal device that is safe and can exert an extremely high sterilizing and algicidal effect.

Note that, also in the present embodiment, the cylindrical electrode 4 'has a plurality of water passage openings 4'a.

Next, in a fourth embodiment, as shown in FIG. 6, instead of the cylindrical electrode 4 or the cylindrical electrode 4 ′ shown in the second or third embodiment, In addition, a semi-cylindrical body electrode 5 formed in a semi-cylindrical shape is used. The semi-cylindrical body electrode 5 is made of the same material as the cylindrical body electrode 4 or the cylindrical body electrode 4 ', but has no water passage opening 4a or 4'a and is formed in a thin plate shape.

Is not limited.

Next, the power supply device 17 is used in all embodiments of the present invention, and has a role of supplying electricity to the ion / chlorine generator 16. It also has functions to control the switching of electricity and the amount of electricity.

FIG. 7 is a schematic diagram showing a water circulation system in which the sterilizing and algicidal device according to the present invention is implemented. Among them, 11 is a water facility such as a pond, a pool, a water tank, etc., 12 is a water supply source such as a filter, a tank, and a water supply for supplying water to the water facility 11, and 13 is a connection between the water supply source 12 and the water facility 11. , A flow path through which a predetermined amount of water flows. An ion / chlorine generator 16 is provided in the flow path 13 via various valves 15 (bypass valve 15a, drain valve 15b). The ion / chlorine generator is connected to a power supply 17 via an output cable 18.

The water circulating in the water circulation system is added with sodium chloride (NaCl) necessary for generating chlorine. The concentration of salt in water may be relatively low, but its value is specifically determined by the type of water facility and the amount of water.

Then, the water containing the salt is supplied from the water supply source 12 into the ion / chlorine generator 16 through the suction port 1 a ′ via the flow path 13, and the cylindrical electrode 4 or 4 ′ or the semi-cylindrical When the body electrode 5 is used as an anode and the rod-shaped body electrode 3 is used as a cathode, sodium chloride is electrolyzed to generate chlorine (hypochlorous acid).

On the other hand, when the cylindrical electrode 4 or 4 ′ or the half-cylindrical electrode 5 is used as a cathode and the rod electrode 3 is used as an anode, the rod electrode 3 is electrolyzed, and a metal ion such as copper or silver is formed. Occurs. At this time, the generated metal ions are attracted to the cathode, but titanium has a property that it is difficult to generate hydrogen gas. Therefore, the charge of the generated metal ions is not lost, and the metal does not return to the original metal, so that the decrease in the content of the metal ions can be reduced and the deposition of the metal powder near the cathode can be prevented. It can be significantly reduced.

Here, the anode and cathode of the electrode are set by the power supply device 17 so as to be automatically switched at predetermined time intervals. The switching from the anode to the cathode and the switching from the cathode to the anode are considered as one cycle. For example, by setting such that several cycles can be performed in one hour, the water containing stable metal ions and chlorine (hereinafter referred to as “water”) can be obtained. , Electrolyzed water).

In the illustrated examples of the first to third embodiments, the water flowing into the casing 1 from the suction port 1 a ′ passes through the water passage opening 4 a or 4 ′ a and faces the rod-shaped body 3 and the suction wall 1 a. While turbulent in the casing 1 while containing metal ions and chlorine generated by the above action, and flows out to the discharge port 1b. Also in the fourth embodiment, since the semi-cylindrical body electrode 5 has the same role as the inner wall of the casing 1, the same operation and effect can be obtained. The method of attaching the casing 1 and the lid 2 to the casing 1 shown in the first to fourth embodiments is merely an example, and for example, a casing (a casing in which a suction port and a discharge port are provided to face each other). (Not shown), the rod-shaped electrode 3 and the cylindrical-shaped electrode 4 or 4 'or the semi-cylindrical-shaped electrode 5 may be disposed so as to be located between the suction port and the discharge port. In this case, the water that has flowed in from the suction port is almost laminar and flows out to the discharge port while containing metal ions and chlorine. Further, the lid 2 may be fixed to the casing 1 with screws or the like.

The electrolytic water produced as described above is sent from the discharge port 1 b to the water facility 11 via the flow path 13. Then, in the water facility 11, water sterilization and algicidation are performed. Further, the water facility 11 is provided with a drain 19 and a drain port 20, and a part thereof is used for a fountain 23 via a hair strainer 21, a circulating pump 22, or another hair strainer 24. The water is sent to the filter 12 via the circulation pump 25 and the like, and the water filtered by the filter 12 is sent again to the water facility 11 through the flow path 13 and circulated.

Here, the electrolyzed water has a synergistic effect with chlorine due to the catalytic action of the metal ions. Therefore, the electrolyzed water is about 10 times to 1000 times as compared with the conventional disinfection and algicidal apparatus of a water facility using only metal ions. An extremely high germicidal and algicidal effect can be achieved. Further, in addition to eliminating the need for using a chlorine-based chemical, chlorine contained in the electrolyzed water formed through the electrolysis step is about 1/10 to 1/50 as compared with the case where the chlorine-based chemical is used. Since it has the same bactericidal and algicidal activity at a residual chlorine concentration of a certain level, it is possible to suppress the occurrence of adverse effects such as those that occur when using the above-mentioned chlorine-based chemicals. Furthermore, the chlorine contained in the electrolyzed water loses its activity in a short time after sterilization of the water facility, and returns to a low concentration of dissolved salt. Therefore, once sodium chloride is added to the refluxing water, it is not necessary to re-add sodium chloride for a long time, so it is efficient in terms of labor and cost, and is safe for the user and environmentally friendly. Easy. Further, when it is desired to increase or decrease the sterilizing and algicidal power depending on the state of contamination of the water facility, the amount of generated metal ions and chlorine can be increased or decreased by adjusting the amount of current in the power supply device 17. Therefore, it is possible to efficiently and extremely easily sterilize and kill water with water.

[Effect of the invention]

 According to the present invention, an ion / chlorine generator is disposed in water containing a required concentration of salt, and when electricity is supplied, chlorine is generated in addition to metal ions such as silver. The synergistic effect with chlorine is produced by the catalytic action of the above, so that an extremely high effect of about 10 to 1000 times can be achieved as compared with the case where the water is sterilized and treated with only metal ions.

According to the present invention, the rod-shaped electrode and the cylindrical electrode or the semi-cylindrical electrode are alternately switched to the anode and the cathode, and energized, so that calcium, silica, metal powder, etc. The adhesion of solid deposits (scale) to the electrode can be significantly suppressed, and the electrode can be cleaned up very easily.

Further, according to the present invention, a remarkably excellent bactericidal and algicidal effect of water in a water facility can be obtained without using a chlorine-based chemical. Since the amount of chlorine can be adjusted, the method of use is simple and the cost is reduced.In addition, the durability of the system that circulates water to the water facility itself is improved, and it is safe and comfortable for the human body. Water facilities can be provided to users.

Further, according to the present invention, most of the metal ions generated once (about 70% or more) diffuse into water without returning to the original metal again. The algae can be maintained, and the precipitation of metal powder can be greatly reduced, thereby preventing water in the water facility from being contaminated.

Further, since the cylindrical body electrode or the semi-cylindrical body electrode is formed of titanium, it has high corrosion resistance, and is coated with platinum, so that it is durable. If the coating becomes thin, it can be used as many times as it is coated with platinum again, so it is economical, and because it can be recycled, it can contribute to the effective use of resources and, consequently, environmental protection.

Further, since the cylindrical electrode or the semi-cylindrical electrode covers the periphery of the rod-shaped electrode, the rod-shaped electrode is efficiently dissolved by the electrolytic action, so that it can be effectively used.
