FIG. 7B is an enlarged view showing a portion A in FIG.

  The electrolysis module 20 includes a decomposition unit 210, a separation plate 220, and a case 230. The disassembly unit 210 and the separation plate 220 are housed in a case 230.

  The case 230 has a cylindrical shape as a whole, and has an inflow hole 231 formed at a lower portion and two outflow holes 232 and 233 formed at an upper portion. Raw water flows into the inlet 231 from the raw water power supply unit 10, and acid water and alkaline water are separated into the outlet holes 232 and 233 and supplied to the external power supply unit 30.

  A plurality of decomposition units 210 are provided, and a separation plate 220 is disposed between adjacent decomposition units 210. In each of the decomposition units 210, as shown in FIG. 4, the acidic water and the alkaline water are separated and generated, and the acidic water and the alkaline water generated in each of the decomposition units 210 are discharged to the outside without being mixed with each other. . The number of disassembly units 210 is not limited, and only one may be used. When the single disassembly unit 210 is used, the separation plate 220 may be omitted.

  The decomposition unit 210 includes a support 211, a separation membrane 212, a first electrode 213, a second electrode 214, and application electrodes 215 and 216.

  The support 211 has a hollow disk shape, and the separation membrane 212 is coupled to the support 211. Although not shown, a structure is provided inside the support body 211 in which raw water is supplied and discharged to the electrodes 213 and 214, and the electrolyzed electrolyzed water is separated and discharged to the outside.

  The separation film 212 suppresses the passage of water, and allows ions and electrons to pass so that current can flow on both sides of the separation film 212. Specifically, the separation membrane 212 may have a pore size of 0.1 μm to 0.6 μm, 0.2 μm to 0.6 μm, and 0.2 μm to 0.4 μm. The separation membrane 212 may be formed of Teflon (registered trademark), but is not limited thereto.

  The first electrode 213 is located on one surface of the separation film 212, and the second electrode 214 is located on the other surface. Each of the electrodes 213 and 214 has a plate-like mesh form. The electrodes 213 and 214 may be variously deformed without being limited to the mesh shape as long as the electrodes allow the water to flow therein. The electrodes 213 and 214 may be formed by coating titanium with a noble metal, but are not limited thereto. The electrodes 213 and 214 having a mesh shape may have a thickness of 0.1 μm to 2 μm, 0.2 μm to 1 μm, or 0.5 μm to 1.0 μm.

  The application electrodes 215, 216 are located above the electrodes 213, 214, and the application electrodes 215, 216 are electrically connected to the electrodes 213, 214.

  Each of the electrodes 213 and 214 can make surface contact with the separation membrane 212. The application electrodes 215 and 216, the electrodes 213 and 214, and the separation film 212 may be in contact with each other, and in this case, the movement of the electrodes 213 and 214 is limited.

  Hereinafter, the electrolysis process in the electrolysis module 20 will be described.

  When a power source having a different polarity is applied to each of the electrodes 213 and 214 via the application electrodes 215 and 216, electrolysis is started.

  In this process, raw water is supplied along the separation membrane 212. That is, the raw water is converted into electrolyzed water while flowing (parallel) through the electrodes 213 and 214, but the raw water or the electrolyzed water moves smoothly because the electrodes 213 and 214 are in a mesh form. .

  At this time, the flow of raw water passing through the electrodes 213 and 214 is a laminar flow. Since the raw water flows in a laminar flow and the pores of the separation membrane 212 are very small, the mixing of the electrolytically decomposed water between the electrodes 213 and 214 does not substantially occur or is very small. Raw water is electrolyzed while passing through the electrodes 213 and 214 in a plate-like direction.

  Hereinafter, an operation method of the above-described electrolyzed water generation device 1 will be described.

  First, raw water is supplied to the electrolysis module 20 via the raw water power supply unit 10. The raw water supply unit 10 supplies tap water, fresh water, or salt water to the electrolysis module 20.

  Thereafter, the electrolysis module 20 separates and generates acidic water and alkaline water by electrolysis. The generated acidic water and alkaline water are supplied to a user (use destination) via the external power supply unit 30.

  The pH of the acidic water may be between 5.0 and 6.5, between 5.5 and 6.0, between 5.5 and 6.5, or between 6.0 and 6.5. When using salt water, the residual chlorine concentration of the acidic water may be 5 ppm to 40 ppm, 10 ppm to 40 ppm, 10 ppm to 30 ppm, or 10 ppm to 20 ppm.

When the salt water is electrolyzed, it is decomposed into sodium and chloride ions, and hypochlorite (HOCl) and hydrogen (H ₂ ) are generated while the chlorine molecules, which are the coordination bond form of the chloride ions, are oxidized again. You. Here, the hypochlorous acid is further decomposed into hydrogen ions (H +) and hypochlorite ions (HCl−), and the hypochlorite ions later combine with sodium separated from sodium chloride. Forms sodium hypochlorite.

  Eventually, the electrolyzed salt water equilibrates under certain conditions and is composed of hydrogen, sodium hypochlorite, hypochlorous acid, and hypochlorite ions. Here, sodium hypochlorite and hypochlorous acid both have a disinfecting effect, but since hypochlorous acid has about 70 times the sterilizing effect as compared with sodium hypochlorite, In order to improve the germicidal power the proportion of hypochlorous acid must be increased.

  However, the composition ratio of hypochlorous acid and hypochlorite ion may vary depending on the hydrogen ion concentration (pH) as shown in FIG. As shown in FIG. 10, the production amount of residual chlorine, hypochlorous acid, and sodium hypochlorite changes depending on the pH.

That is, hypochlorous acid (HOCl) is formed by combining hydrogen ions (H ⁺ ) and hypochlorite ions (OCl ⁻ ), and when the pH is 4.3 to 5.9. , With the maximum bactericidal power. When the pH is low, electrolysis is not performed with chlorine, and when the pH is high, hypochlorite ions combine with sodium to generate sodium hypochlorite.

  On the other hand, if the pH is 4.0 or less, chlorine gas may be generated. Therefore, in the present invention, the pH of the acidic water is adjusted to 5.0 to 6.5, 5.5 to 6.0, 5.5. To 6.5, or 6.0 to 6.5.

  In the present invention, since the acidic water and the alkaline water are separated and produced by the configuration of the separation membrane 211 and the like, the pH of the acidic water can be easily adjusted. Accordingly, it is possible to supply acidic water having a pH at which hypochlorous acid having a high bactericidal power is generated, thereby reducing the chlorine content of the acidic water and reducing the amount of salt or salt water used. .

  The pH of the alkaline water can be controlled to 10 or more, 11 or more, or 12 or more.

  The additional raw water supply unit 40 is used to adjust the pH and / or the residual chlorine concentration of the acidic water.

  The acidic water supplied according to the present invention can be used for sterilization in homes, cafeterias and the like. Alkaline water is used in the agricultural field. If necessary, the acidic water and / or alkaline water can be used after being stored in a separate tank. Particularly, in the case of alkaline water, it can be used after being stored in a separate tank.

  In the above-described generation of the electrolyzed water, if power of the same polarity is continuously applied to the first electrode 213 and the second electrode 214, foreign matter accumulates on the negative electrode and damages the positive electrode. Occurs. Therefore, the control unit 50 changes the polarity of the power supply applied to the two electrodes 213 and 214 under certain conditions, for example, after a certain operation time has elapsed.

  When the polarity is changed, the operation can be performed such that the outlets of the acidic water and the alkaline water discharged from the electrolysis module 20 are changed. At this time, the transfer path of the acidic water and the alkaline water is changed using the flow path switching valves 313 and 323 and the connection pipes 331 and 332, and the external power supply unit 30 supplies the acidic water and the alkaline water at a predetermined position. Will be.

  In another embodiment, when the polarity of the power supply of the electrolysis module 20 changes to prevent mixing of the acidic water and the alkaline water, the acidic water and the alkaline water are used for a certain period of time, for example, 3 seconds to 5 minutes. Can be exhausted without At the time of discharge, the movement path of the acidic water and the alkaline water changes or is maintained.

  Thereafter, the polarity of the power supply of the electrolysis module 20 is changed again to supply the acidic water and the alkaline water, or the acid power and the alkaline water are continuously supplied while the changed power supply polarity of the electrolysis module 20 is maintained. Can be. At this time, the external power supply unit 30 supplies the acidic water and the alkaline water at predetermined positions using the flow path switching valves 313 and 323 and the connection pipes 331 and 332.

  In another embodiment, when the polarity of the power supply of the electrolysis module 20 changes, the moving path is changed and both the acidic water and the alkaline water can be discharged through the alkaline water pipe 321 for a certain time. After that, the polarity of the power supply is changed again, and the moving path is changed to supply the acidic water and the alkaline water at a fixed position. This method can be applied when the alkaline water is not used for another purpose or the alkaline water can be stored in a tank before use to accommodate a temporary pH change.

  When it is determined that the supply of the service water and / or the supply of the salt water is interrupted or insufficient by the flow meter 75 or the like, the control unit 50 can interrupt the generation of the sterilizing water by controlling the power supply unit 60 and the like. When the control unit 50 is not used for a long time by the timer 71 or the like, the control unit 50 can supply only the water without supplying the electrolyte to wash the electrolysis module 20, and the electrolysis module 20 has been operated for a predetermined time or more. In this case, the display section 65 can notify the replacement time to the outside. The display 65 may be a warning lamp and / or a warning sound using an LED or the like, and may be notified by a separate display device.

  8A to 8C are diagrams showing other forms of the electrodes 213 and 214. FIG.

  The electrodes 213 and 214 maintain a plate shape in a mesh form, and have an uneven embossing form. The embossing mode is to make the flow of raw water smoother. FIGS. 8A to 8C do not show a mesh form.

  The embossing may be scattered over the electrodes 213 and 214 as shown in FIG. 8A, or may be formed in a certain direction as shown in FIGS. 8B and 8C. FIG. 8B shows a case where the direction of formation of the grooves by embossing is parallel to the flow direction of raw water, and FIG. 8C shows a case where the direction of formation of the grooves by embossing is at a certain angle, for example, perpendicular to the flow direction of raw water. The size of the embossing can be variously provided within the same electrode 213, 214.

  In other embodiments, only one of the electrodes 213 and 214 may have an embossing configuration or a different embossing configuration.

  FIG. 9 shows an electrolyzed water generator according to a second embodiment of the present invention.

  The difference from the first embodiment is that the flow path switching valve 323 and the connection pipe 331 are not provided. Thereby, the acidic water can be discharged to the outside through both the pipes 311 and 321, but the alkaline water is discharged to the outside only through the alkaline water pipe 321.

  In the second embodiment, when the power supply polarity of the electrolysis module 20 changes, both the acidic water and the alkaline water can be discharged to the alkaline water pipe 321 for a certain period of time by changing the moving route. After that, the polarity of the power supply is changed again, and the moving route is changed to supply the acidic water and the alkaline water at fixed positions.

  When using salt water in the present invention, acidic water can be used as sterilizing water containing hypochlorous acid. The alkaline water can be drained.

  When salt water is not used, acidic water having a pH of 4 or less and alkaline water having a pH of 11 or more are discharged. The obtained acidic water and alkaline water can be used in the agricultural field.

  Acid water and alkaline water were produced using the electrolyzed water generator 1 described above.

  The salt water flow rate (saturated salt water) was 7.2 ml / min, the tap water flow rate was 1000 ml / min, the current was 5 A, and the voltage was 4.8 V. As a result of using four decomposition units, acidic water (pH 3.75) was obtained. , Chlorine concentration 58 ppm) and alkaline water (pH 11.86, salt water residual concentration 3 ppm or less).

  By changing the amount of salt water / tap water used, changing the current / voltage, and supplying additional raw water, it is possible to obtain acidic water and alkaline water of desired quality.

  Next, without using salt water, the flow rate of tap water was 1000 ml / min, the current was 5 A, and the voltage was 20.2 V. As a result of using four decomposition units, acidic water (pH 4.2) and alkaline water were used. Water (pH 11 or higher) was obtained.

  Even when salt water is not used, desired quality acidic water and alkaline water can be obtained by changing tap water usage, changing current / voltage, and supplying additional raw water.

  While the present invention has been described with reference to an embodiment shown in the accompanying drawings, this is merely an example and various modifications will occur to those skilled in the art. It will be appreciated that and other equivalent embodiments are possible. Accordingly, the actual scope of protection of the present invention should be determined only by the attached claims.
