OPEN-CELL TYPE APPARATUS FOR PREPARING SODIUM HYPOCHLORITE

摘要

The present invention relates to an apparatus for preparing sodium hypochlorite by electrolysis using soft water and salt, comprising: a hypochlorite generator (20) which accommodates a plurality of electrode plates (25) to form a flow channel (21a) inside, and has an intake (23) and an outlet (24) communicated with the flow channel (21a); a cooling means (50) which is connected to the intake (23) of the hypochlorite generator (20) and lowers the temperature of the flow channel (21a); and a control means (80) for detecting the temperature of the hypochlorite generator (20) to control the operation of the cooling means (50). Accordingly, the generation of harmful materials is inhibited by maintaining the optimum temperature at all times and the efficiency of an electrolyte is remarkably improved by reducing the hardness of the cation deposited on a cathode, and thus a high concentration of sodium hypochlorite can be produced.
