In water facilities such as swimming pools and various factories, it is necessary to hygienically manage the water used and the pipes to which the water is transferred. In order to sterilize water and clean the pipes, water electrolysis is often used.
즉, 배관에 전기분해장치를 연결하고, 배관으로 이송되는 물에 전해질을 첨가하여 물을 전기분해하는데, 이와 같이 하면, 물이 전기분해되어 살균처리될 뿐만 아니라 전기분해에 의해 발생되는 전해질의 산화, 환원성에 의해 배관에 부착된 슬러리가 이온화되어 제거됨에 따라 배관이 청소된다.In other words, the electrolysis device is connected to the pipe, and the electrolyte is added to the water transferred to the pipe to electrolyze the water. In this way, the water is electrolyzed and sterilized, as well as oxidation of the electrolyte generated by the electrolysis. As the slurry adhered to the pipe is reduced by ionization, the pipe is cleaned.
따라서 급수펌프 등이 구비된 급수배관에 별도의 전기분해장치를 설치하여 주기적으로 전기분해장치를 작동시켜서 물과 배관을 살균 및 청소한다.  Therefore, by installing a separate electrolysis device in the water supply pipe with a water supply pump, etc. periodically operate the electrolysis device to sterilize and clean the water and pipes.

At this time, the water flowing into the inlet 102 is discharged to the drain 104 through the dilution space 320 of the electrolytic cell 300. The water flowing into the dilution space 320 is electrolyzed by the tip of the electrode 330 protruding into the dilution space to generate hydrogen ions and hydroxide ions, and the water is first sterilized by oxidation and reducing power of these ions. do.
한편, 상기 전극(330)에 전류가 인가되면, 전해조(300)의 염산투입공(302)을 통해 전해공간(310)으로 유입되는 묽은 염산은 전해공간(310)에서 전기분해되어 염소가스가 발생된다. 이때 발생되는 염소가스는 전해물질배출공(309)을 통해 희석공간(320)으로 배출되고, 희석공간(320)의 물에 용해되어 차아염소산, 즉, 차아염소산수가 발생된다. 물론, 이때 염소가스의 일부는 전해공간(310)에서 용해되어 차아염소산 형태로 희석공간(320)으로 배출되기도 하다.On the other hand, when a current is applied to the electrode 330, the dilute hydrochloric acid introduced into the electrolytic space 310 through the hydrochloric acid injection hole 302 of the electrolytic cell 300 is electrolyzed in the electrolytic space 310 to generate chlorine gas do. The chlorine gas generated at this time is discharged into the dilution space 320 through the electrolyte discharge hole 309 and dissolved in water in the dilution space 320 to generate hypochlorous acid, that is, hypochlorous acid water. Of course, at this time, some of the chlorine gas is dissolved in the electrolytic space 310 may be discharged to the dilution space 320 in the form of hypochlorous acid.
전술한 바와 같이, 묽은 염산이 전기분해되어 생성된 염소가스에 의해 희석공간(320)에는 차아염소산수가 생성되어 출수공(306)으로 배출된다. 이와 같이 생성된 차아염소산수에 의해 물이 2차 살균되고, 배관도 살균되며, 배관의 슬러리가 제거되어 배관이 청소된다. As described above, hypochlorous acid water is generated in the dilution space 320 by the chlorine gas produced by the electrolysis of the dilute hydrochloric acid and discharged to the water extraction hole 306. The water is secondaryly sterilized by the hypochlorous acid solution thus generated, the pipe is also sterilized, and the slurry of the pipe is removed to clean the pipe.
한편, 전술한 바와 같이, 염산이 전기분해되어 생성된 염소가스가 물에 용해됨에 따라 차아염소산이 생성되어 차아염소산수를 얻게 되지만, 아래의 화학식과 같이 염소가스의 일부는 염산으로 재생성되며, 이에 따라 차아염소산수의 pH가 낮아진다. On the other hand, as described above, as the chlorine gas generated by hydrolysis of the hydrochloric acid is dissolved in water, hypochlorous acid is generated to obtain hypochlorous acid water, but a part of the chlorine gas is regenerated with hydrochloric acid as shown below. Therefore, the pH of hypochlorous acid water is lowered.
H2O + Cl2 → HOCl + HClH 2 O + Cl 2 → HOCl + HCl
그런데 차아염소산수는 pH5~6.5의 미산성 수준에서 가장 우수한 살균력을 갖기 때문에, 차아염소산수의 살균력을 향상시키기 위해서는 차아염소산수의 pH를 미산성 수준으로 높일 필요가 있다. By the way, since hypochlorous water has the best sterilizing power at the microacid level of pH 5 ~ 6.5, it is necessary to increase the pH of hypochlorous acid water to the microacid level to improve the sterilizing power of hypochlorous acid water.
일반적으로는 차아염소산수를 희석시키는 희석수의 공급량을 증가시켜서 차아염소산수의 pH를 미산성 영역으로 조절하는데, 이와 같은 방법을 사용하면, 차아염소산수의 pH는 미산성 영역으로 조절되나 차아염소산수의 차아염소산 농도가 저하되어 높은 살균력을 갖지 못하게 되는 문제점을 가진다.In general, by increasing the amount of dilution water for diluting hypochlorite water, the pH of hypochlorite water is adjusted to the non-acidic zone. With this method, the pH of hypochlorite water is adjusted to the non-acidic zone, but hypochlorous acid Hypochlorous acid concentration of water is lowered has a problem that does not have a high sterilizing power.
그러나 본 발명에서는 희석공간(320)에서 재 생성된 염산이 상기 전극(330)의 희석공간(320)으로 연장된 선단부에 의해 전기분해되어 전술한 바와 같은 반응에 의해 차아염소산이 생성된다. 이와 같이, 전극(330)에 의해 희석공간(320)에서 재 생성된 염산이 전기분해됨에 따라 차아염소산수의 pH는 상승되고, 차아염소산수의 차아염소산농도가 증가된다. 따라서 살균력이 우수한 고농도의 미산성 차아염소산수를 얻게 된다. However, in the present invention, hydrochloric acid regenerated in the dilution space 320 is electrolyzed by the tip portion extending to the dilution space 320 of the electrode 330 to generate hypochlorous acid by the reaction as described above. As such, as the hydrochloric acid regenerated in the dilution space 320 by the electrode 330 is electrolyzed, the pH of the hypochlorous acid water is increased, and the hypochlorous acid concentration of the hypochlorous acid water is increased. Therefore, a high concentration of the acidic hypochlorous acid water having excellent sterilization power is obtained.
또한, 희석공간(320)에서 생성된 차아염소산수는 모터(200) 임펠러(210)의 회전력에 의한 흡입력에 의해 출수공(306)으로 배출되는데, 이때 발생되는 흡입력에 의해 임펠러(210)에 근접되는 부위에는 고압이 발생되고, 이에 따라 전술한 바와 같은 과정에서 미처 제거되지 못하고 잔존하는 염소가스의 용해도가 상승되며, 이에 따라 차아염소산의 농도가 증가된다. In addition, the hypochlorous acid water generated in the dilution space 320 is discharged to the water outlet 306 by the suction force by the rotational force of the impeller 210 of the motor 200, the close proximity to the impeller 210 by the suction force generated at this time The high pressure is generated at the site, thereby increasing the solubility of the remaining chlorine gas without being removed in the above-described process, thereby increasing the concentration of hypochlorous acid.
한편, 이러한 전기분해과정에서 전극(330) 표면에는 스케일이 생기게 되는데, 전극의 전해공간(310)에 위치되는 부분은 전해공간(310)에 주입되는 염산에 의해 스케일이 제거되고, 전극(330)의 희석공간(320)으로 위치되는 부분은 전술한 바와 같이, 희석공간(320)에서 발생되는 염산에 의해 스케일이 제거된다. On the other hand, a scale is formed on the surface of the electrode 330 during the electrolysis process, the portion located in the electrolytic space 310 of the electrode is removed by the hydrochloric acid injected into the electrolytic space 310, the electrode 330 As described above, the portion located in the dilution space 320 is descaled by hydrochloric acid generated in the dilution space 320.
이와 같이 전극(330)의 스케일이 효과적으로 제거되기 때문에, 전극(330)의 스케일을 없애기 위해 전극(330)을 분리하여 세척하거나 또는 전류를 역으로 걸어주는 등의 수고를 하지 않아도 되는 장점이 있다.As such, since the scale of the electrode 330 is effectively removed, there is an advantage that the effort of removing the electrode 330 by removing the electrode 330 or removing the scale of the electrode 330 or applying a reverse current is not required.
바람직하게는 펌프의 구동을 제어하는 제어부는 펌프로 유입되는 유량에 따라 상기 전극(330)의 전류량, 묽은 염산의 유입량 등이 자동으로 조절되도록 프로그래밍된다. Preferably, the control unit for controlling the driving of the pump is programmed to automatically adjust the amount of current, the amount of dilute hydrochloric acid, etc. of the electrode 330 according to the flow rate flowing into the pump.
이와 같은 구성을 가지는 본 발명은 수영장을 비롯하여 각종 시설의 급수배관에 설치되어 사용되는데, 펌프를 통해 물이 급수되면 펌프 내부의 전해조(300)에서 생성되는 차아염소산수가 물에 혼합되어 물이 살균되고, 배관 내부의 슬러리가 제거되어 배관이 세척되며, 전극(330)의 스케일도 효과적으로 제거된다.  The present invention having such a configuration is installed and used in water supply pipes of various facilities including a swimming pool, when water is supplied through a pump, hypochlorite water generated in the electrolytic cell 300 inside the pump is mixed with water to sterilize the water. The slurry in the pipe is removed to clean the pipe, and the scale of the electrode 330 is also effectively removed.
따라서 본 발명은 배관에 물을 살균하거나 배관을 청소하기 위한 별도의 전기분해장치를 구비하지 않아도 되는 장점이 있다.Therefore, the present invention has the advantage of not having to provide a separate electrolysis device for sterilizing water or cleaning the pipe.
