Sodium hypochlorite (NaOCl), used as an electrolytic disinfectant, is produced by the electrolysis of brine. First, a chlorine ion (Cl -) in the salt (NaCl) is converted with chlorine gas (Cl 2) through the positive reaction. In this case, the anode reaction is competitive with oxygen (O 2) generation reaction by the decomposition of water (H 2 O), and the efficiency is determined according to the characteristics of the anode electrode, the salt concentration and the electrolysis method. During the anodic reaction, hydrogen gas (H2) and hydroxide ion (OH-) are generated through the decomposition of water (H2O) in the cathode and hydroxide ion (OH-) meets sodium ion (Na +), A reaction occurs. The chlorine gas (Cl2) generated by the electrode reaction reacts with caustic soda (NaOH) to produce sodium hypochlorite (NaOCl). The reactions are summarized as follows.

    A chlorine water tank 106 for storing chlorine water from the sodium hypochlorite generating portion;
    A chlorine water transfer pump (P5) for pumping chlorine water in the chlorine water tank and supplying the chlorine water into the water tank;
    Using the information on the current chlorine concentration in the water tank and the information on the chlorine concentration in the chlorine tank, when the chlorine concentration in the water tank is not the predetermined target chlorine concentration, the chlorine water transfer pump is controlled and injected into the water tank And the temperature of the chlorine water in the sodium hypochlorite generating part is used to divide a part of the chlorine water supplied into the water tank by the chlorine water transfer pump to warm the temperature of the chlorine water, A control panel (110) for controlling the temperature of the chlorine water in the sodium hypochlorite generating portion by being conveyed to the sodium chlorate generating portion;
    A temperature sensor for measuring the temperature of the chlorine water in the sodium hypochlorite generating portion and providing the information to the control panel as information on the temperature of the chlorine water in the sodium hypochlorite generating portion;
    A chlorine concentration meter for measuring the chlorine concentration in the chlorine water tank and providing the chlorine concentration information to the control panel side as information on the chlorine concentration in the chlorine water tank;
    A flow meter for measuring an injection amount of chlorine water injected into the water tank by the chlorine water transfer pump; And
    The temperature of the chlorine water supplied to the water tank by the chlorine water transfer pump is diverged to be sent to the sodium hypochlorite generating section so that the temperature of the chlorine water in the sodium hypochlorite generating section is kept constant And a controller for controlling the operation of the chlorine-water disinfection unit.
