ELECTROLYTIC VESSEL FOR USE IN PRODUCTION OF AQUEOUS HYPOCHLOROUS ACID

Document Type and Number:

WIPO Patent Application WO/2014/168024

Kind Code:

A1

Abstract:

[Problem] To provide an electrolytic vessel for use in the production of aqueous hypochlorous acid, which does not undergo the leakage of a chlorine gas, is stable for a long period and has good efficiency. [Solution] An electrolytic vessel (1) and a water-feeding passage (6) are formed in a casing (2) that has a sufficient thickness so as to absolutely prevent the leakage of a chlorine gas from the casing (2) and is made from vinyl chloride, wherein the electrolytic vessel (1) is provided with an electrolytic chamber (3) that is provided with a cathode and an anode both for generating a chlorine gas and a hydrogen gas upon the feeding of dilute hydrochloric acid to the electrolytic chamber (3) and a gas reservoir (4) arranged above electrode plates (5a, 5b) of the cathode and the anode, and the water-feeding passage (6) penetrates through the electrolytic vessel (1). The chlorine gas generated in the electrolytic chamber (3) is mixed with water that flows in the water-feeding passage (6) so that the chlorine gas can be dissolved satisfactorily to secure safety in the water-feeding passage (6). On the other hand, the hydrogen gas enters into the water-feeding passage (6) while keeping the gaseous form thereof, then returns to a storage tank (14) and is then diffused from an upper part of the storage tank (14) into air in the form of a hydrogen gas, because the hydrogen gas can be dissolved in water poorly.
