Abstract
The invention relates to a hypochlorous acid molecular solution preparation device which comprises a hypochlorous acid generator, wherein the hypochlorous acid generator comprises an electrode assembly, the electrode assembly comprises an anode assembly and a cathode assembly, the anode assembly comprises an anode sheet, the anode sheet is a coating electrode sheet, a coating film is composed of any one or more of three oxides of ruthenium oxide, iridium oxide and rhodium oxide, a conductive agent and an adhesive, the cathode assembly comprises a cathode sheet, and the cathode sheet is composed of one or more materials selected from titanium, stainless steel and graphite.
Description
Technical Field
The invention relates to the technical field of chemical oxidation reaction, in particular to a hypochlorous acid molecular solution preparation device.
Background
With the coming of the post epidemic situation era, the living quality and health consciousness of people are obviously improved. Mainly characterized in that the problems of disinfection, sterilization, air purification, food safety and the like are more and more emphasized in daily life, and particularly, the requirements on removing various chemical residual substances (such as pesticide residues, medicine residues, formaldehyde and the like) are higher and higher.
In the existing sterilization technology, when used for food, the heat treatment and chemical sterilization methods can affect the quality and nutritional ingredients of the food, also can affect the oxidation rate, protein structure, original flavor and the like, and residual sterilizing agents can cause harm to human bodies, animals, plants and the environment; ultraviolet sterilization can generate a light revival phenomenon due to a sterilization action mechanism, and needs to be used in an unmanned environment, and can cause harm to the skin and eyes of people if the operation is not proper; in the ozone sterilization technology, because ozone molecules are extremely unstable, the ozone molecules are easy to decompose and generate toxic substances simultaneously, and the sterilization effect is limited; the ultrahigh pressure technology cannot be used in daily life due to high equipment requirements.
The sodium hypochlorite disinfectant has the characteristics of good sterilization effect, relatively simple preparation method and the like, and has high market share. And in order to satisfy the demand of using conveniently, have domestic sodium hypochlorite antiseptic solution preparation facilities on the existing market. For example, CN212983073U discloses a small-sized apparatus for preparing sodium hypochlorite disinfectant, which uses the reaction of electrolyzing saline solution to prepare sodium hypochlorite disinfectant from saline solution as raw material, but the apparatus still has the following problems:
(1) chlorine is volatile and toxic, and can pollute the environment;
(2) excessive hydrogen is easily generated, and when the concentration of the hydrogen and chlorine is higher than 5%, visible light explosion is generated;
(3) at the same time, a large amount of trichloromethane which is a strong carcinogen can be generated;
(4) the amount of the added salt is not well controlled, the generated concentration is not controllable, and the generated solution can only be used for disinfection, is harmful to human bodies and cannot be directly sprayed on human bodies or animals.
One of the effective bactericidal components of the sodium hypochlorite disinfectant is hypochlorous acid generated by the hydrolysis of sodium hypochlorite, the hypochlorous acid is a safe disinfectant which is only clearly used for air disinfection by the comprehensive group of defense health committee and state hospital for coping with the novel coronavirus pneumonia and epidemic situation joint prevention control mechanism, and the hypochlorous acid is also a disinfectant which is specified by the US FDA and can be used as a no-clean food-grade disinfectant at the concentration of below 60 ppm. Since hypochlorous acid is a small molecule and is uncharged, the main component of the human leukocyte immune function can not only act on cell walls but also permeate into bacteria, and can cause the rupture of the cell walls and cell membranes by destroying the outer membranes and inactivating proteins in plasma membranes, inhibit the action of enzymes, destroy the metabolic processes of cells, permeate into the cells and destroy the cell walls and organelles of microorganisms in the cells, thereby causing the death of the bacteria.
In the prior art, a technique for sterilizing by using slightly acidic electrolyzed water, also called slightly acidic hypochlorous acid water, is available. Has the characteristics of high bactericidal effect, no color or odor, high safety and environmental friendliness. Slightly acidic electrolyzed water is generally obtained by electrolyzing dilute hydrochloric acid, and for example, CN112042667A discloses a method for preparing an aqueous hypochlorous acid solution by an electrolytic reaction using water, dilute hydrochloric acid and common salt as raw materials. However, the technique needs dilute hydrochloric acid or salt and the like as raw materials, and the proportion of adding the salt or the dilute hydrochloric acid is not easy to master, and particularly, the dilute hydrochloric acid has strong acidity and corrosivity and is not easy to operate; on the other hand, the method for preparing hypochlorous acid water generates a large amount of polluted waste water at the same time, and is poor in economical efficiency and environmental protection.
