Title:
DEVICE FOR PRODUCING ACIDIC HYPOCHLOROUS ACID WATER
Document Type and Number:
WIPO Patent Application WO/2024/009609
Kind Code:
A1
Abstract:
One aspect of the present invention prevents the occurrence of a situation in which a sodium hypochlorite aqueous solution and a strong acid aqueous solution are simultaneously supplied to a column due to a problem such as an erroneous operation or malfunction in the production of an acidic hypochlorous acid water by a device that carries out an operation of producing weak acidic hypochlorous acid water from a sodium hypochlorite aqueous solution through an ion exchange column method and then regenerating the column with a strong acid aqueous solution, the operation being carried out by operating each opening/closing valve and pump, etc. on the basis of a signal transmitted based on program control. Another aspect of the present invention is characterized by equipping a production device with a control mechanism that detects, for example, the type of an open/close command signal that is sent to an opening/closing valve (FA) of a pipe that supplies the sodium hypochlorite aqueous solution and to an opening/closing valve (FB) of a pipe that supplies the strong acid aqueous solution, or the presence of fluid inside both pipes, and if a state is entered in which said opening/closing valves can simultaneously become "open", the control mechanism forcibly closes one or both of the opening/closing valves regardless of the type of signal sent by the program.
