Generator and method for continuously generating slightly acidic hypochlorous acid

Abstract

The invention discloses a generator and method for continuously generating slightly acidic hypochlorous acid. The generator comprises at least one group of three-cavity electrolytic cell and a circulating water tank, wherein electrolysis chambers 1 to 3 are respectively arranged between a negative plate and a diaphragm, between the diaphragm and a positive plate and between the positive plate and a regulating negative plate in the three-cavity electrolytic cell; the bottom of each electrolysis chamber is provided with an input port, and the upper part of each electrolysis chamber is provided with an output port; input and output ports of the electrolysis chambers 2 and 3 are connected with the right chamber of the circulating water tank through water pumps; the input port and the output port of the electrolysis chamber 1 are connected with the left chamber of the circulating water tank through water pumps; high-concentration salt water is input into the circulating water tank and a high-concentration salt water tank through water pumps, and liquid generated in the right chamber is input into an HClO storage water tank; and the current of the regulating pole pieces and the negative plate is adjustable. According to the above scheme, the generation efficiency of the hypochlorous acid can be improved, and the pH value and the available chlorine concentration of the generated hypochlorous acid can be adjusted according to actual requirements.

Description

technical field [0001] The invention relates to the field of chemical production and disinfection, in particular to a generator for continuously generating microacid hypochlorous acid and a generating method. Background technique [0002] Slightly acidic hypochlorous acid water, also known as slightly acidic electrolyzed water (SAEW for short), slightly acidic oxidation potential water, has a pH value of 5.0-6.8 and has a high bactericidal effect, which is almost equal to the bactericidal effect of sodium hypochlorite at the same concentration. ten times. It exists only in solution, concentrated solution is yellow, dilute solution is colorless, high concentration has a very pungent, chlorine-like smell, and is extremely unstable, it is a very weak acid, weaker than carbonic acid, and hydrogen sulfuric acid quite. Hypochlorous acid disinfectant is an emerging disinfection product, which has been demonstrated as one of the safe, effective and environmentally friendly disinfe...

Problems solved by technology

With the increasing scale of production, it was found that the original design idea was not only to enlarge the equipment, but also brought more technical problems. For example, the third patent used multiple electrolyzers to work together, but in actual production It is found that the production scale still has low production efficiency, low hypochlorous acid content, and it is not very convenient to use, so the design needs to be more suitable for large-scale production.
