Description

Liquid generating device and liquid ejecting device
Technical Field
The present invention relates to the field of disinfectants, and more particularly, to a liquid generating device and a liquid ejecting device.
Background
Chlorine dioxide disinfectants are internationally recognized high-efficiency disinfectants, and the safety of the chlorine dioxide disinfectants is classified as AI grade by the World Health Organization (WHO). It can kill all microorganisms including bacterial propagules, bacterial spores, fungi, mycobacteria and viruses, and these bacteria do not produce drug resistance. Chlorine dioxide has strong adsorption and penetration capacity on microbial cell walls, can effectively oxidize enzymes containing sulfydryl in cells, and can quickly inhibit the synthesis of microbial proteins to destroy microbes. (data source "science popularization China").
Chlorine dioxide is different from other chlorine series disinfectants such as bleaching powder, sodium dichloroisocyanurate, trichloroisocyanuric acid, 84 disinfectant and the like, is not a chlorinating agent but a strong oxidant, has a sterilizing effect not influenced by a pH value, has strong diffusion speed and permeability in water and has lasting sterilizing capability.
The practical application shows that the chlorine dioxide concentration of 0.5ppm can keep 99% of killing rate to colibacillus, the efficacy can be kept above 12 hours, the sterilizing capability is 5 times of chlorine and 50 times of sodium hypochlorite, and the microorganism is not easy to generate drug resistance, and has good killing and inhibiting effects on typhoid fever, hepatitis A, hepatitis B, poliomyelitis, AIDS virus and the like.
Chlorine dioxide is widely used in developed countries such as the united states, germany, france, finland, canada, japan, etc. for disinfection and mildew prevention of foods, pharmaceutical products, hospitals, public environments, etc., and for preservation of foods, and becomes the only high-efficiency disinfectant and sterilization agent among chlorine-containing disinfectants recognized internationally. (data source: China chemical industry society inorganic acid base salt professional committee chlorine dioxide expert group expert surcharge).
At present, the domestic preparation methods of chlorine dioxide mainly comprise a reduction method and an oxidation method.
The reduction method is a widely used method at present.
According to the difference of the selected reducing agent, the method can be divided into a sulfur dioxide reduction method, a hydrochloric acid reduction method, a sodium chlorate reduction method, a methanol reduction method and the like. Among them, the methanol reduction method is a main industrial production method of chlorine dioxide. The main reaction formula is as follows:
30NaCIO3+7CH3OH+20H2SO4=30ClO2↑+6HCOOH+10Na3H(SO4)2+23H2O+CO2↑。
different reducing substances can be selected as reducing agents, and hydrochloric acid, oxalic acid, chlorine and the like have good reducing effects. The preparation reaction formula is as follows.
A hydrochloric acid method: NaClO3+2HCl=ClO2↑+1/2Cl2↑+NaCl+H2O；
An oxalic acid method: 2NaClO3+2H2SO4+H2C2O4=2ClO2↑+2CO2↑+2H2O+2NaHSO4；
A chlorine method: 2NaClO2+Cl2=2ClO2↑+2NaCl。
The oxidation method is to use an oxidant (Cl)2Or NaClO) oxidizing NaClO2Or NaClO in an acidic medium2Disproportionation reaction to produce ClO2. The sodium chlorite oxide method can be classified into a chlorine gas oxidation method, an autooxidation method, and a hypochlorous acid oxidation method.
Chlorine oxidation method: 2NaClO2+Cl2=2ClO2↑+2NaCl；
An autoxidation method: 5NaClO2+4HCl=4ClO2↑+5NaCl+2H2O；
Hypochlorite oxidation process: 2NaClO2+NaClO+2HCl=2ClO2↑+3NaCl+H2And O. (data sources: Yiying, Wujinhui, Heoli Mei, etc.. Advance and trend of research on application technology of gas chlorine dioxide, J.China Disinfection science (2017), 34(4): 360-.
The raw materials currently used to produce chlorine dioxide solutions all contain strong oxidants such as sulfuric acid (H)2SO4) Or hydrochloric acid (HCl), the product is not suitable for the general population for storage, transportation and handling, and the chemical reaction produces sodium bisulfate (Na 3H (SO)4)2) And the environment is polluted. If liquid chlorine (Cl) is used2) Production of chlorine dioxide due to liquid chlorineThe risk is higher when the health-care product is used, and carcinogenic Trichloromethane (THMs) is easily generated in the process. (data source: stability of beautiful jade Chenhui pure chlorine dioxide and Baidu conventional conditions storage method research of China Petroleum and chemical industry Standard and quality)
The property of chlorine dioxide is extremely unstable, and the stable chlorine dioxide solution of the binary preparation on the existing market is extremely easy to decompose or convert into chlorite (ClO)2 -) Chlorate radical (ClO)3 -) And hypochlorite (ClO)-) Although chlorite and chlorate still have strong oxidation sterilization effect, the secondary products have high residual quantity in water to affect human health (such as hemolytic anemia and the like). (data source: stability of beautiful jade Chenhui pure chlorine dioxide and Baidu conventional conditions storage method research of China Petroleum and chemical industry Standard and quality)
The prior storage method of the chlorine dioxide solution comprises the following steps: low-temperature storage, and the storage time cannot be overlong; can also be converted into chlorite (ClO) by the reaction of a stabilizer with chlorine dioxide2 -) The product can be stored, and can be used by adding activator to generate chlorine dioxide, thereby having antibacterial effect. (data source: study progress of stability of chlorine dioxide of Happy ring Panhuiyun [ Water treatment Standard and quality ])
The method has the disadvantages of troublesome operation and more side reactions, and is not suitable for common people. This is also the main reason why chlorine dioxide disinfectants are not widely used in daily life at present.
In the prior art, chemical substances participating in the reaction need to be stored separately, and the generated chlorine dioxide needs to be solidified by a stabilizer and can be obtained by adding an activating agent when in use. The chlorine dioxide solution is easily decomposed into Chlorite (CLO) in the long-term storage process2a-ClO) and Chlorate (CLO)3A vertical section), disinfection effect is lost. The preparation, transportation, storage, activation and other steps have strong specialization, and the method is not suitable for disinfection and use in families, hospitals, units and other environments to solve the technical problems and becomes a difficult problem to be solved urgently.
