Electrolysis system for preparing hypochlorous acid water

Abstract

The invention relates to an electrolysis system for preparing hypochlorous acid water. The electrolysis system comprises an electrolysis bath, a tap water supply pipeline, a hypochlorous acid water discharge pipeline and a hydrochloric acid supply pipeline, wherein the electrolysis bath is divided into an internal groove for accommodating hydrochloric acid electrolyte and an external groove for tap water to flow through; an electrolytic strip is arranged in the internal groove; an electrolyte intake hole is formed at the lower end of the internal groove; a chlorine exhaust port communicated with the external groove is formed at the upper end of the internal groove; a water inlet hole for the tap water to flow in is formed on the lower side of the external groove; a water outlet hole for the hypochlorous acid water to flow out is formed on the upper side of the external groove; one end of the tap water supply pipeline is connected with a water inlet pipe, while the other end is connected with the water inlet hole; one end of the hydrochloric acid supply pipeline is connected with a hydrochloric acid container, while the other end is connected with the electrolyte intake hole; and one end of the hypochlorous acid water discharge pipeline is connected with the water outlet hole, while the other end is connected with a hypochlorous acid water container or is used directly. The electrolysis system has a simple structure and can effectively improve the generation rate of the hypochlorous acid water; and the produced hypochlorous acid water has sterilization, disinfection and environmental protection effects.

Description

technical field [0001] The present invention relates to an electrolysis system, more specifically, relates to an electrolysis system for preparing hypochlorous acid water. Hydrochloric acid is electrolyzed to generate chlorine gas, and the generated chlorine gas is mixed with water to generate hypochlorous acid containing hypochlorous acid. Chloric acid water. Background technique [0002] Hypochlorous acid water is acidic electrolyzed water containing hypochlorous acid molecules (HClO). It is a kind of water with a pH of 5.0-6.5 and an effective chlorine concentration of 10-30 mg / L. This hypochlorous acid water has a strong oxidation resistance. Ability and rapid killing of microorganisms. The existing electrolysis system for preparing hypochlorous acid water includes an electrolytic cell, tap water supply pipeline and hypochlorous acid water discharge pipeline, and the tap water supply pipeline supplies tap water added with salt NaCl to the electrolytic cell. The anode a...

Problems solved by technology

[0003] Yet the existing electrolysis system that is used to prepare hypochlorous acid water mainly has following problems: 1) adopt the tap water that has added common salt Nacl as raw material, need utilize the electrolyzer that has ionic membrane to generate hypochlorous acid water, however the ionic membrane The price is expensive, and it is easy to block during the electrolysis process, which affects the electrolysis efficiency; and, in the production process of the existing double-slot diaphragm electrolysis method, the anode tank gets hypochlorous acid water, and the cathode tank gets the same amount of alkaline water, while the alkali 2) During the electrolysis process, high current will generate heat through the electrolytic sheet, which will increase the impedance of the electrolytic sheet, reduce the current flow, affect the production of chlorine gas, and then affect the generation of hypochlorous acid water Efficiency; 3) Chlorine and water are mixed in the electrolytic cell, but there will be a small amount of chlorine that is not mixed with water, which affects the generation efficiency of hypochlorous acid water; 4) water flow, electrolyte flow and pH value of hypochlorous acid water It is not effectively controlled, so that the generated hypochlorous acid water does not meet the requirements of the pH value, so it is necessary to improve the existing electrolysis system for preparing hypochlorous acid water
