Embodiment 1

[0032] A method for preparing hypochlorous acid by two-liquid synthesis combined with microporous molecular sieves of the present invention comprises the following steps:

[0033] S1. Use the pre-filter 1 to process tap water to obtain purified water; the water flow rate is adjusted to 5L / min, and the water pressure is 0.5MPa. 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.

Abstract

The invention discloses a method and equipment for preparing hypochlorous acid by combining two-liquid synthesis with a microporous molecular sieve, and the preparation method comprises the followingsteps: 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 diluting device 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 of which the pH value is 4.0-6.8 and of which the concentration is 10-5000ppm; and S4, filtering the hypochlorous acid mixed solution in the step S3 through a microporous molecular sieve to remove impurities except hypochlorous acid and water molecules, thereby obtaining a subacid hypochlorous acid product. The product disclosed by the invention is stable in performance, good in sterilization and disinfection effects, long in preservation time, non-toxic and odorless.

Description

technical field [0001] The invention relates to the field of hypochlorous acid production, in particular to a method for preparing hypochlorous acid by two-liquid synthesis combined with microporous molecular sieves, and also relates to a device used in the above production method. 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 env...
