Problems solved by technology

However, this sodium hypochlorite solution or calcium hypochlorite solution is easy to react with organic matter in the environment to generate trihalomethanes. It has been proved in animal experiments that trihalomethanes can cause gene mutation or carcinogenesis, so the chlorine disinfection used in the prior art Drugs have strong toxic side effects

Abstract

The invention provides an apparatus for preparation of hypochlorous acid water. The apparatus includes: a water inlet device; a mixer with a first inlet connected to the outlet of the water inlet device; an electrolytic device with a chlorine gas outlet connected to a second inlet of the mixer; an electrolyte solution sampling device with an outlet connected to the electrolytic device inlet; and a control system for controlling the electrolytic device, the water inlet device and the electrolyte solution sampling device. The hypochlorous acid water preparation apparatus provided by the invention includes the control system, which controls the electrolytic device, the water inlet device and the electrolyte solution sampling device, by controlling the electric current of the electrolytic device, the water inflow of the water inlet device and the electrolyte solution transport flow of the electrolyte solution sampling device, the obtained hypochlorous acid water has a low content of available chlorine. The hypochlorous acid water prepared by the apparatus provided by the invention does not have excessive free chlorine, and cannot form trihalomethane with organic matters in the environment. Therefore, the hypochlorous acid water is safe and harmless to serve as a disinfectant.

Description

technical field [0001] The invention relates to the technical field of disinfectants, in particular to a device and method for preparing hypochlorous acid water. Background technique [0002] Disinfectants are used to kill pathogenic microorganisms on the transmission medium, so that the transmission medium can meet the requirements of harmlessness. At the same time, disinfectants can also cut off the transmission route of infectious diseases and achieve the purpose of controlling infectious diseases. At present, the disinfectants used on the surface of objects mainly include ozone-based disinfectants, alcohol-based disinfectants and chlorine disinfectants. Among them, chlorine disinfectants have a wide range of applications and can be used for human skin and mucous membranes, drinking water, tableware, melons and fruits. Disinfection of vegetables and environment etc. [0003] Chlorine disinfectant in the prior art mainly is sodium hypochlorite or calcium hypochlorite, and...
