Embodiment 1

[0024] A kind of technology for preparing hypochlorous acid by a two-liquid method combined with an electrolysis method of the present invention comprises the following steps: S1, using a pre-filter 1 to process tap water to obtain purified water; wherein the water flow rate is adjusted to 5L / min, and the water pressure is 0.5 MPa. The pre-filter 1 is a three-stage filter device, and the three-stage filter device includes a 1 micron microporous PP cotton filter 11 connected in sequence, a second-stage activated carbon filter 12, and an acidic cation exchange resin filter 13. The micron microporous PP cotton filter 11 filters out large particle impurities in tap water; the second-stage activated carbon filter 12 absorbs organic matter and microbial impurities in tap water; the acidic cation exchange resin filter 13 filters out heavy metal impurities in tap water and cations. S2, in hypochlorite solution diluter 2, add hypochlorite solution and purified water in step S1, obtain...

Abstract

The invention discloses a process and equipment for preparing hypochlorous acid by combining a two-liquid method with an electrolytic method. The hypochlorous acid preparation process comprises the following steps: S1, treating tap water by adopting a pre-filter to obtain purified water; S2, adding a hypochlorite solution and the purified water in the step S1 into a hypochlorite solution dilutingdevice to obtain a hypochlorite diluted solution; S3, adding the hypochlorite solution and an acidic solution in the step S2 into a mixer for mixing reaction to obtain a hypochlorous acid mixed solution; and S4, electrolyzing the hypochlorous acid mixed solution obtained in the step S3 through an electrolysis device to convert chloride ions in the solution into hypochlorous acid molecules, reducethe content of the chlorine ions in the solution, and remove heavy metal ions to obtain a subacid hypochlorous acid product.

Description

technical field [0001] The invention relates to a process for preparing hypochlorous acid by a two-liquid method combined with an electrolysis method, and also relates to a production equipment for preparing hypochlorous acid. 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 pri...
