Description

A kind of system producing stable antiseptic solution

Technical field

The present invention relates to disinfection fields, and in particular to a kind of system for producing stable antiseptic solution.

Background technique

Currently, common sterilizing method is mainly by physical method, chemical method and three kinds of biological method, wherein physics Sterilization is mainly that means such as radiosterilization, thermal disinfection, mechanical disinfection of physics etc. is used to kill or eliminate pathogenic microorganism, General nontoxic, environmental pollution is less, but limited there are effect and poor universality limitation;Chemical disinfection is to utilize change It learns drug to act on certain specific pathogenic microorganisms to achieve the purpose that kill germ, common chemicals is containing chlorine Thimerosal, milk of lime, formalin, Peracetic acid etc., the use of a large amount of chemicals is there is drug residue so that generating The problem of environmental pollution;Biological sterilization is that pathogen is removed using biotic factor, and effect is slowly and sterilizing is not thorough.

Chlorine-containing disinfection liquid is one of effective fungicide most common so far, and effective component is hypochlorous acid or secondary chlorine Barbiturates.According to U.S. environment protection mechanism studies have shown that the sterilizing ability of hypochlorous acid under the same conditions is hypochlorous acid salt It is tens of to hundreds of times.In fact, people just had found that hypochlorous acid has potent bactericidal effect before more than 100 years.Hypochlorous acid It is a kind of very weak acid, and it is existed only in solution, there is very strong oxidisability, while hypochlorite solution for human body and moves Object safety with higher, the irradiation of chance ultraviolet light will decompose after reacting with organic matter and noresidue generates, to environment There is no any burden.Therefore, it is each to be widely used in each row such as individual, family, medical treatment, agricultural, animal husbandry for hypochlorous acid Disinfection, cleaning, nursing of industry etc..

There are Cl in hypochlorite solution2、HClO、ClO-Dynamic equilibrium, and it is numerous studies have shown that hypochlorous acid and secondary The sterilizing ability of solution of chlorate all mostlys come from hypochlorous acid molecule.When pH is 4.0-6.5, hypochlorous acid molecule is in aqueous solution In have ratio highest, that is, the strongest state of its sterilizing power;When pH value is lower than 3.0, chlorine generation is had, acidity is got over By force, the ratio of chlorine is bigger, will release from solution when chlorine reaches a certain concentration;It, can be to people because chlorine is toxic Body causes damages safely.Therefore, the production of hypochlorite solution, it should be ensured that pH value is in zone of reasonableness, so that hypochlorous acid molecule is dense It spends high as far as possible.But the reactivity and unstability high due to hypochlorous acid, cause its industrialized production always can not be real It is existing.Therefore, scientists are being attempted to realize hypochlorous industrialized production using various methods always.

So far, the research of hypochlorous acid industrialized production, is concentrated mainly on electrolysis method and chemical method.Wherein electrolysis method is raw Parity chloric acid not only needs to consume a large amount of electric energy, and the expensive noble metal electrode used easily damages, so that production equipment uses It is at high cost, it is difficult to which that the available chlorine content for the hypochlorite solution for safeguarding, and being produced by electrolysis method is usually no more than 80mg/L, simultaneously Impurity is more.The too low hypochlorite solution of concentration, not only sterilizing ability is limited, but also is difficult to stablize preservation, can only now-making-now-using, Thus it is extremely restricted its extensive use.In addition, electrolysis method generate hypochlorite solution pH it is lower (generally 2-4, because And also referred to as acidic oxidized electric potential water), pH wider range, it is difficult to accurately control pH value, and because hypochlorous acid itself is unstable easily point The characteristic of solution, once decomposing can be such that the acidity of system further enhances, it is easy to and cause chlorine to generate.

And chemical method is mainly the reaction next life parity chloric acid for passing through highly basic and chlorine, chlorine and hypochlorite contact method are come Produce hypochlorous acid.Chemical method produces hypochlorous acid starting a little later, and realization of industrialization is complicated.But chemical method has considerable hair in recent years Exhibition, such as report use CO2Hypochlorous acid is generated with sodium hypochlorite hybrid reaction, but production process is unstable, can generate a large amount of Sodium carbonate or sodium bicarbonate, easily cause production pipeline to block;Also have and be mixed to get by sodium hypochlorite or calcium hypochlorite with water.But This preparation method cannot be directly used to daily disinfection and sterilization and inconvenient for use;Etc..However, in fact chemical method also with institute The electrolysis method mentioned there are the problem of it is similar, hypochlorous acid is unstable, the acidity of system can be made to be remarkably reinforced after decomposition, easily generated The chlorine toxic to human body.In other words, the shelf-life of the hypochlorous acid system of above method preparation is very limited.So due to The problem of stability, that is, shelf-life, cannot be well solved, so that hypochlorite solution has been limited to now-making-now-using at present, And then its extensive use is caused to receive very big limitation.

PH value is adjusted after generally first mixing acid & alkali liquid in the device of the stable hypochlorite solution of existing production, then will The mixed mixed liquor of acid & alkali liquid and chloranion provide agent solution and raw water is mixed to form hypochlorite solution, due to first will Then acid & alkali liquid mixing provides agent solution hybrid reaction with chloranion again, will increase the equipment for mixing acid & alkali liquid, increases The cost of production.
