Different Kind Liquids Mixing Device and Disinfectant Generator by Electrolysis using That}

The present invention relates to a sanitary installation, and more particularly, to a device for producing a disinfecting water by electrolysis method by mixing the water and the brine in a predetermined ratio using a ventry tube and sending it to the reactor.

In modern times, the population is densely populated, group meals and meals are frequent, and the movement of the population is large due to the development of transportation. As a result, bacterial infectious diseases frequently occur and are becoming a wide area. In this situation, the importance of hygiene cannot be overemphasized. In accordance with such living conditions, various kinds of disinfecting water generating devices have been developed and used.

As a method of generating disinfectant water, it is common to use a chemically prepared disinfectant diluted with water. Diluted disinfectant water using these chemicals may be odor, harmful to humans, and the disinfectant may remain for a long time to contaminate the water quality.

In order to overcome the above problems, a number of methods have been developed for generating disinfectant water by generating sodium hypochlorite (NaOCl) by causing an electrolytic reaction to water to which a small amount of salt is added. Sodium hypochlorite has many advantages as a sanitizing disinfectant, such as strong disinfection and not easily decomposed in nature to leave residual pollutants.

Devices generating disinfectant water using the above-described electrolytic reaction take a method of supplying a certain amount of solid saline to the water in the reaction tank, or supplying a high concentration of saline to the reaction tank with a pump. In particular, when a large amount of disinfectant water is used, water and a high concentration of saline solution are continuously supplied to the reactor, and the continuous disinfection water is continuously taken out. Disinfectant water produced in the reactor may be directly connected to a sprayer or stored in a large storage tank.

When salt water is produced by electrolytic reaction of brine, the concentration of brine is an important factor in determining the concentration of disinfectant in the sterilized water together with the time of electrolytic reaction. Therefore, it is necessary to precisely control the concentration of the brine. The method of controlling the concentration of brine in the continuous reaction type sterilizing water generator is to supply high-frequency saline solution into the reactor with a separate precision pump according to the flow rate of the incoming water. It is difficult to make the brine at a constant concentration because it varies greatly, and thus there is a problem that the concentration of the disinfectant of the generated disinfectant water is also not uniform.

As described above, it is important to precisely control the concentration of the brine introduced into the reaction tank in the generation of the disinfectant water by the electrolytic method, and a means of mixing a high concentration saline solution with water to automatically generate a proper concentration of saline is required.

The present invention is to solve the above technical problem, it provides a means to maintain a constant brine concentration of the reaction tank by automatically adjusting the amount of saline supply according to the amount of water flowing into the reaction tank.

In order to solve the above technical problem, the present invention was provided with a mixing device 100 using a venturi tube 130 to which Bernoulli principle is applied as a means of automatically mixing a high concentration of saline solution in water at a constant ratio.

In addition, the end of the mixing device 100 was configured to add a disinfection water generating device in which the reaction tank 200 in which the electrolysis of saline occurs.

The mixing apparatus 100 of the present invention automatically replaces another type of liquid (high concentration saline) in one liquid (water) which is rapidly infiltrated, instead of the operation of a pump or a manual operation by a user. Mix.

When used in the disinfection water generating device for generating the disinfection water by electrolyzing the brine using the mixing device 100, it is possible to continuously generate a uniform concentration of disinfection water without a separate device for supplying high concentration saline. Therefore, the electrolytic reaction occurs continuously and continuously for a long time, so that the user does not need to periodically supply the salt, so that the unmanned disinfection water generating facility or facility is possible.

In particular, the mixing apparatus 100 of the present application may be applied to mixing a certain ratio of the fluid which is not only the generation of sterilized water, but also two or more kinds of liquids or gases having different properties.

Mixing apparatus 100 of the present invention is a shape of the venturi tube 130 using the Bernoulli principle, as shown in Figure 1, the structure is simple, but a constant amount of high concentration of saline solution is continuously supplied to the water used for electrolysis.

Mixing apparatus 100 of the present invention using a ventry tube, as shown in Figure 1, a saline solution supply tank 110 for supplying a high concentration of saline solution, a ventry tube 130 for diluting a high concentration of saline in raw water (water), and the As the central part of the ventry tube 130, the ventritic tube 130 is composed of a ventritic tube 140 which is a portion where raw water and a high concentration of saline are mixed and diluted.

As shown in FIG. 2, the water supplied through the ventry pipe 130 is supplied through the water pipe, and the high concentration saline is supplied through the saline inlet pipe 120.

The water is quickly passed through the ventry tube 130 by the water pressure of the tap water, especially near the ventry tube 140, the cross-sectional area of the ventry tube 130 is narrowed, the water flow rate is increased to the maximum. According to Bernoulli's principle, as the flow rate increases, the pressure decreases, so that a large flow rate near the ventry tube 140 lowers the pressure of water flowing through the ventry tube.

The amount of saline connected to the vent tree pipe 140 is proportional to the pressure difference between both ends of the saline inlet pipe 120. As described above, the high concentration of the saline solution flowing into the vent tree pipe 140 of the vent tree pipe 130 is the flow rate of the inflow water. The higher the flow rate, the greater the pressure difference, so that more concentrated saline solution is supplied and diluted in water. Therefore, despite the change in the flow rate of the water to be introduced, a nearly constant concentration of the mixed solution is made.

The brine (hereinafter referred to as "salt") mixed with water and high concentration saline is introduced into the reactor 200 connected to the downstream side of the ventry tube 130.

The reactor 200 is a place where the electrolytic reaction for disinfection water generation occurs, as shown in FIG. 3, an electrolytic device connection unit 230 formed in the reactor body 210, the electrolytic apparatus 220, and the reactor body 210. Consists of When the disinfecting water storage tank 300 is added and carried out, the disinfecting water transfer pipe 240 may be further provided to transfer the disinfecting water generated in the reaction tank to the disinfecting water storage tank 300.

If the disinfection water storage tank 300 is located at a higher position than the reaction tank 200 or in order to quickly and smoothly transfer the disinfection water, the pump 125 may be further provided in the disinfection water transfer pipe 240.

Reactor 200 is a shape as shown in Figure 3, the reactor body 210 is attached to the electrolytic device 220 is manufactured in a rectangular or circular tubular shape in consideration of the production efficiency and space utilization, inflow The electrolyte solution should be sized properly to deliver as much salt solution as possible. The reactor body 210 may be made of various materials, but plastic systems, such as polyethylene and nylon, which are not corroded by chemical substances such as sodium hypochlorite, which is a main component of disinfectant water, and hypochlorous acid and ozone, which are incidentally generated in small amounts, good. The downstream end of the ventry tube 130 is connected to the upper end of the reactor body 210 is the brine required for the generation of disinfection water is introduced.

Electrolytic device 220 is the electrolytic device body 222 is coupled to the electrolytic device connecting portion 230 provided in the reactor body 210 with a bolt or the like. In addition, the electrolytic device body 222 is provided with a plurality of electrodes 221, respectively + and-poles are applied through the DC power supply 223, respectively.

The arrangement of the electrodes 221 and the number of the electrodes 221 of the electrolytic apparatus 220 in which electrolysis can be performed can be variously performed. As an example, as shown in FIG. 3, the electrolytic apparatus 220 may be coupled to the lower end of the reactor 200. Alternatively, it may be carried out in combination with the upper end of the reaction vessel (200). In this case, when combined with the upper end, there is no need to perform watertight treatment or the like on the coupling part.

Hereinafter, the electrolysis for generating disinfecting water of the electrolytic device 220 will be described.

When the brine is filled in the reactor 200 and DC power is supplied, electrolysis occurs at each electrode as follows.

Anode _{^{reaction: 2Cl - => Cl 2 +}} 2e -

Cathodic Reaction: 2Na ⁺ + 2e ^- => 2Na

2Na + 2H ₂ O => 2NaOH + H ₂

Total reaction inside the reactor 200: Cl ₂ + 2NaOH => NaOCl + NaCl + H ₂ O

Chlorine (Cl ₂ ) is produced at the anode, sodium hydroxide (NaOH) is produced at the cathode, and hydrogen (H ₂ ) is produced. This sodium hydroxide reacts with chlorine produced at the cathode to produce sodium hypochlorite (NaOCl), salt (NaCl) and water (H ₂ O). In addition, small amounts of oxygen, hydrogen, chlorine and ozone are generated.

NaOCl produced in the chemical reaction, that is, sodium hypochlorite has a strong bactericidal action, the solution of the reaction vessel 200 containing sodium hypochlorite can be used as sterilizing water. In the end, the disinfectant aquatic growth value of the present application is an apparatus for generating disinfectant water using this sodium hypochlorite.

As described above, a few gases are generated in the reaction, and in order to prepare for an abnormal situation such as an increase in pressure in the reactor 200 due to the generation of a large amount of gas, an exhaust port 211 is provided in the upper part of the reactor body 210 in some cases. ) May be required.

Disinfection water storage tank 300 is a part for storing the disinfection water generated in the reaction tank (200). As shown in FIG. 4, the disinfecting water storage tank 300 may be provided with a water level sensor 320 for detecting the water level of the storage body 310 and the disinfecting water storage tank 300 forming the external shape. The water level detector 320 is attached to the inside of the disinfecting water storage tank 300 is operated in such a way as to stop the generation of disinfecting water when the stored disinfection water rises above a certain level.

The jet device 400 may be implemented in various forms. It can be carried out by spraying by disinfecting the disinfecting water into a small hole using a pump or a compressor, or by spraying it with a thin water in the form of a shower nozzle, or in the form of a stream of water as if water is coming from a general faucet. It may be performed to eject.

The controller 500 may include a power supply device and a control circuit. The power supply can be powered on or off manually or automatically. In addition, the electrolytic device 220 should be supplied with a direct current power source, and a power supply device should be provided with a stop that changes the AC power to a direct current power source. The control circuit receives a signal such as the water level detector 320 and emits a signal to cut off or supply power to the electrolytic device 220 or the jet device 400.

Looking in more detail, as shown in Figure 4, the control valve is installed in the saline inlet pipe 120 through which the ventry tube 130 and the high concentration saline solution is introduced into the raw water. If the level of the disinfectant water storage tank is above a certain level and it is no longer possible to store the disinfectant water in the disinfectant water storage tank, the control unit 500 detects the signal of the water level detecting device 320 and closes the control valve to supply the brine to the reactor. At the same time, the power supply to the DC power supply 223 of the electrolytic device 220 is cut off so that the electrolytic reaction no longer occurs. On the contrary, when the level of the sterilizing water storage tank is below a certain level and it is necessary to replenish the sterilizing water to the sterilizing water storage tank any more, the control unit 500 detects the signal of the water level detecting device 320 and opens the control valve to the brine tank. At the same time, power is supplied to the DC power supply unit 223 of the electrolytic apparatus 220 so that the electrolytic reaction occurs again.

In the case of discharging the disinfecting water generated in the disinfecting water generating tank 200 without the sterilizing water purifier 300, a control valve may be installed in the disinfecting water transfer pipe 240 connected to the spraying device 400. The control valve supplies the disinfectant water during the operation of the spout, and blocks the disinfectant water during the non-operational operation, and is controlled by the control unit 500.

In addition, the controller performs various other controls necessary for implementing the present invention. Such a power supply device or a control circuit of the controller can be easily implemented by those skilled in the art having basic knowledge of control.
