APPARATUS FOR MANUFACTURING OF WEAK-ACIDIC HYPOCHLOROUS ACID WATER AND MANUFACTURING METHOD OF WEAK-ACIDIC HYPOCHLOROUS ACID WATER

摘要

An apparatus for manufacturing weak-acidic hypochlorous acid water is provided to generate hypochlorous acid water with high concentration, control acidity of the hypochlorous acid water, prevent blockage of a spray nozzle, and reduce the amount of univalent chloride to be used. An apparatus for manufacturing weak-acidic hypochlorous acid water comprises the following units. An electrolytic cell with a separating film(30) separates a cathode chamber(320) and an anode chamber(310) by an anion penetration diaphragm(34). Univalent chloride aqueous solution is circulated in the cathode chamber of the electrolytic cell with a separating film. The Univalent chloride aqueous solution is electrolyzed in the anode chamber of the electrolytic cell with a separating film.
