Electrolysis device and electrolysis method for preparing hypochlorous acid

Abstract

The invention discloses an electrolysis device and an electrolysis method for preparing hypochlorous acid. The electrolysis device comprises a box body provided with an acid inlet and a gas outlet, and an electrode sheet group located in the box body, wherein the electrode sheet group is formed by arranging a plurality of electrode sheets at intervals; an electrode conducting end led out of the box body is fixed on each of the electrode sheets at the head and the tail in the electrode sheet group; and the chlorine gas generated through electrolysis in the electrolysis device is discharged through the gas outlet and mixed with an aqueous solution to obtain a hypochlorous acid aqueous solution. In the electrolysis method, a hydrochloric acid solution is used as an electrolysis solution, the electrode sheets are made from platinum-plated metallic titanium, and the chlorine gas is generated through electrolysis. According to the electrolysis device disclosed by the invention, the electrode sheet group is adopted, the electrode sheets are arranged at intervals, the electrode sheets at the head and the tail are connected with the positive pole and the negative pole of an external power supply respectively, and the electrode sheet arranged at the middle participating in an electrolysis reaction through a weak current in the electrolysis solution instead of being directly connected with electricity. The electrolysis device disclosed by the invention is capable of generating the chlorine gas with an enough amount under a small volume, and hypochlorous acid water with a disinfection effect can be obtained through a reaction between the chlorine gas and water.

Description

Technical field: [0001] The invention relates to the technical field of disinfection equipment, in particular to an electrolysis device and an electrolysis method for preparing hypochlorous acid. Background technique: [0002] The chemical formula of hypochlorous acid is HClO, and the structural formula is H-O-Cl, which exists only in solution, and the dilute solution is colorless. Hypochlorous acid is a very weak acid, but it has a strong oxidizing and bleaching effect, so hypochlorous acid water can be used as a disinfectant for sterilization. After research, hypochlorous acid water has a fast sterilization speed and good effect, and has a strong deodorizing power. At the same time, hypochlorous acid water is relatively safe for humans and animals, and it will decompose after reacting with organic matter or being exposed to ultraviolet rays, without producing residues and causing no load on the environment. [0003] Based on the bactericidal effect of hypochlorous acid, ...

AI Technical Summary

Problems solved by technology

[0005] 1. In the process of electrolysis, enough hypochlorous acid cannot be produced, resulting in insufficient concentration of hypochlorous acid water, and the pH value cannot be controlled within a reasonable range

[0006] 2. Whether the current electrolysis process uses a diaphragm or no diaphragm, the electrolysis process is difficult to control, and if hypochlorous acid water with a pH value within a reasonable range is to be produced, the chamber of the electrolysis device usually needs to be large enough, so Also caused the volume of the whole device to be larger
