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

preparation example Construction

[0042] The device for preparing hypochlorous acid water provided by the present invention includes a control system that can control an electrolysis device, a water inlet device, and an electrolyte solution sampling device, by controlling the current of the electrolysis device, the water inlet amount of the water inlet device, and The electrolyte solution sampling device is used to control the flow rate of the electrolyte solution, thereby controlling the amount of chlorine and water entering the mixer, and thereby making the available chlorine content in the hypochlorous acid water lower. The device provided by the present invention is used to prepare The obtained hypochlorous acid water does not have too much free chlorine, and will not form trihalomethanes with organic matter in the environment, so this hypochlorous acid water is safe and harmless as a disinfectant. In addition, the pH value of the hypochlorous acid water prepared by the present invention is in the neutral ra...

Embodiment 1

[0128] use figure 1 The illustrated apparatus for preparing hypochlorous water to prepare hypochlorous water includes the following steps:

[0129] The hydrochloric acid solution with a mass concentration of 5% in the hydrochloric acid tank 1 is delivered to the electrolytic tank 3 through the electromagnetic pump 2, and the controller 8 controls the electromagnetic pump 2 to deliver the hydrochloric acid solution to the electrolytic tank 3 at a speed of 60 mL / h;

[0130] The controller 8 controls the electric current of the electrolytic cell 3 to be 0.7A, and electrolyzes the above-mentioned hydrochloric acid solution in the electrolytic cell 3, and the chlorine gas obtained by the electrolysis is transported to the mixing pipe 4 through the PVC pipe;

[0131] The flow meter 6 tests the flow rate of the tap water delivered by the tap water pipe 5, and sends the obtained test data to the controller 8. The controller 8 controls the solenoid valve 7 according to the test data of the flo...

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, the disinfectant 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 disinfectants, alcohol disinfectants and chlorine disinfectants. Among them, chlorine disinfectants have a wide range of applications and can be used on human skin and mucous membranes, drinking water, tableware, and fruits. Vegetables and environmental disinfection. [0003] The chlorine disinfectant in the prior art is mainly sodium hypochlorite or calcium hypochlorite. Sodium hypochlorite or calci...
