Embodiment Construction

[0025] The method for reducing the residual amount of chlorine ions in electrolyzed water without diaphragm in the present embodiment, the steps are as follows:

[0026] S1: Filter the raw water first;

[0027] S2: Pass the filtered raw water into a storage tank equipped with an electrolysis unit, and the raw water reacts with the electrolysis unit in the storage tank. The electrolysis unit in this embodiment is connected to a DC power supply. In order to remove scale generated on the electrodes, The positive and negative poles of the DC power supply can be switched regularly;

[0028] S3: The electrolyzed raw water enters the electrolyzed water generator through the water pump connected to the storage tank, and the electrolyzed water is produced in the electrolyzed water generator.

[0029] In this embodiment, the electrolysis unit is composed of 4 titanium-based platinum-plated electrodes, and the relevant parameters satisfy the following relationship:

Abstract

The invention discloses a method for reducing the residual amount of chloride ions in diaphragm-free electrolyzed water. The method comprises the following steps: S1, filtering raw water first; S2, introducing the filtered raw water into a storage barrel provided with an electrolysis unit, and carrying out a reaction on the raw water with the electrolysis unit in the storage barrel; and S3: feeding the electrolyzed raw water into diaphragm-free water electrolysis equipment through a water pump connected with the storage barrel, and carrying out electrolyzed water production in the diaphragm-free water electrolysis equipment. The method can be used to realize the technical effect of effectively reducing the residual amount of chloride ions in the diaphragm-free electrolyzed water.

Description

technical field [0001] The invention relates to the technical field of electrolysis methods, in particular to a method for reducing residual chlorine ions in electrolyzed water without a diaphragm. Background technique [0002] Electrolyzed water refers to the general term for aqueous solutions with special functions, which are produced by changing the pH value, oxidation-reduction potential, and available chlorine concentration of the water after the electrolyzed aqueous solution with low concentration is electrolyzed in the electrolytic cell in a special device. . [0003] Electrolyzed water equipment can be divided into diaphragm electrolyzed water equipment and non-diaphragm electrolyzed water equipment according to the type of electrolyzer. [0004] The preparation of acidic electrolyzed water is mostly used to add an appropriate amount of low-concentration dilute hydrochloric acid and / or sodium chloride aqueous solution into the electrolytic cell without a diaphragm, ...
