ELECTROLITIC SODIUM HYPOCHLORITE GENERATING SYSTEM

An electrolytic sodium hypochlorite generating system is provided to supply stable saturated salt water to the electrolytic sodium hypochlorite generating system at all times, minimize space of an electrolytic cell, disassemble or exchange electrodes more conveniently, automatically control the electrolysis current value constantly although flow rate and salt concentration of electrolytic water flowing into the electrolytic cell vary, and use an electrolytic power supply inexpensively and safely. An electrolytic sodium hypochlorite generating system comprises: a water softener(30) for producing and supplying soft water; a salt dissolving tank(50) for dissolving salt to produce saturated salt water and circulating salt water by a salt water circulation pump(58); an electronic cutout valve(43) for introducing salt dissolved soft water into the salt dissolving tank or cutting out supply of the salt dissolved soft water into the salt dissolving tank by a signal of a water level sensor(56) of the salt dissolving tank; a pump(55) for supplying a fixed flow rate of saturated salt water to the electrolysis part; a valve(44) for controlling a fixed flow rate of soft water, a soft water flow meter(45), and soft water flow pipes, which produce electrolytic water of low concentration salt water by diluting the saturated salt water; a salt water diluting pipe(23) for diluting the saturated salt water and diluted soft water to flow the diluted water into the first electrolytic cell; a constant current electrolytic power(10) having a constant current control function capable of generating sodium hypochlorite with a stable concentration; first and second electrolytic cells(21,22) for electrolyzing electrolytic water using an electrolytic current supplied from the constant current electrolytic power, heating electrolytic water with a low temperature, and cooling overheating of the second electrolytic cell; a soft water temperature sensor(80) for measuring temperature of soft water flown into the electrolytic cells; electronic cutout valves(40-42) installed on the soft water flow pipes; a sodium hypochlorite relay tank(60) for temporarily storing sodium hypochlorite received from the second electrolytic cell through a sodium hypochlorite flow pipe(25); a sodium hypochlorite relay pump(59) for flowing sodium hypochlorite into a sodium hypochlorite storage tank of a sodium hypochlorite disinfection system; and a plurality of manual cutout valves(48) for safely cutting out cha
