Description
Technical Field
The invention relates to the technical field of space disinfection, in particular to a water-based chlorine-containing disinfectant compound atomization method applied to three-dimensional space disinfection.
Background
The water-based chlorine-containing disinfectant in the current market basically adopts a single ultrasonic atomization mode, only has an effect on the ground surface and the object surface, the steam fog of the water-based chlorine-containing disinfectant cannot be stagnated, the time existing in the space low-altitude air is shorter, and the effect of sterilizing the space without dead angles cannot be achieved. This places a great limit on the use of water-based chlorine-containing sterilizing fluids for atomization.
For example, hypochlorous acid has the chemical formula HClO, which is an oxyacid of chlorine. Hypochlorous acid solutions are commonly used in disinfectants because of their strong oxidizing nature. The hypochlorous acid disinfectant has the characteristics of safety, no toxicity, peculiar smell removal, low cost and the like because the hypochlorous acid disinfectant can control the effective chlorine content and the PH value, and is widely applied at home and abroad. The hypochlorous acid disinfectant is a disinfectant with wider applicability, is suitable for disinfecting general object surfaces, medical instruments, medical wastes, drinking tools, fabrics, fruits, vegetables, water and the like of medical and health institutions, public health places and families, and can also be used for disinfecting air, secondary water supply equipment surfaces, hands, skin and mucous membranes. Hypochlorous acid disinfectant is a bactericidal factor in the human immune system.
The stability of hypochlorous acid is a major technical problem, and experimental researches show that hypochlorous acid only exists in aqueous solution. The aqueous solution thereof may be concentrated in vacuo to a density of 1.282g/cm3, i.e. a concentration of 40.1%. When hypochlorous acid is heated to 40 degrees or more, the decomposition rate is explosive. 2HClO→2HCl+O 2 ↑，HClO+HCl→H2O+Cl 2 ↑，3HClO→2HCl+HClO 3 Not only lose the disinfection effect but also generate toxic substances Cl 2 . Hypochlorous acid disinfectant has good stability under the condition of ultrasonic low-temperature atomization, and hypochlorous acid has poor disinfection effect when being used at a temperature exceeding 40 ℃ and is easy to generate chemical reaction and harmful gas.
For another example, sodium hypochlorite is a common disinfectant, and the main principle is to disinfect with hypochlorous acid formed by hydrolysis of the disinfectant, and the hypochlorous acid is further decomposed to form nascent oxygen [ O ], so that the protein of thalli and viruses is denatured by the extremely strong oxidizing property of the nascent oxygen, thereby killing pathogenic microorganisms. According to chemical measurements, the hydrolysis of sodium hypochlorite is affected by the pH, which is detrimental to hypochlorous acid formation when the pH exceeds 9.5, whereas for ppm concentrations sodium hypochlorite is almost completely hydrolyzed to hypochlorous acid in water with an efficiency of greater than 99.99%. The process can be expressed simply by chemical equations as follows:
NaClO+H2O＝HClO+NaO
HClO→HCl+[O]
in the process of sterilization and virus killing, hypochlorous acid can act on cell walls and virus shells, has small hypochlorous acid molecules and no charge, and can permeate into a bacterial (virus) body to perform oxidation reaction with bacterial (virus) protein, nucleic acid, enzyme and the like or destroy phosphate dehydrogenase thereof, so that sugar metabolism is disordered to cause cell death, and pathogenic microorganisms are killed.
R-NH-R+HClO.fwdarw.R2NCl+H2O (bacterial protein)
The higher the concentration of sodium hypochlorite, the stronger the bactericidal effect.
Meanwhile, the chloride ions generated by hypochlorous acid can also obviously change the osmotic pressure of bacteria and virosomes, so that cells lose activity and die.
Sodium hypochlorite solutions are commonly used in disinfectants because of their strong oxidizing properties. The sodium hypochlorite disinfectant has the characteristics of safety, no toxicity, peculiar smell removal, low cost and the like because of being capable of controlling the effective chlorine content and the PH value, and is widely applied at home and abroad. The sodium hypochlorite disinfectant is a disinfectant with wider applicability, is suitable for disinfecting the surfaces of general objects, medical instruments, medical wastes, eating and drinking tools, fabrics, fruits and vegetables, water and the like in medical and health institutions, public health places and families, and can also be used for disinfecting the surfaces of air, secondary water supply equipment, hands, skin and mucous membranes.
The stability of sodium hypochlorite is a great technical problem, and experimental researches show that sodium hypochlorite exists only in aqueous solution. The effective bactericidal factor for sodium hypochlorite is hypochlorous acid produced. When hypochlorous acid is heated to 40 degrees or more, the decomposition rate is explosive. 2HClO→2HCl+O 2 ↑，HClO+HCl→H2O+Cl 2 ↑，3HClO→2HCl+HClO 3 Not only lose the disinfection effect but also generate toxic substances Cl 2 . The sodium hypochlorite disinfectant has good stability under the condition of ultrasonic low-temperature atomization, and hypochlorous acid has poor disinfection effect when being used at a temperature exceeding 40 ℃ and is easy to generate chemical reaction and harmful gas. .
