Problems solved by technology

[0003] At present, there are many methods for environmental disinfection (physical and chemical methods), such as: ultraviolet disinfection, 84 disinfectant, 75% alcohol, peracetic acid and other disinfection methods will cause harm to the human body, and most of them have high prices and low sterilization efficiency, which are harmful to the human body. Toxic, not suitable for dynamic continuous disinfection in the presence of people

Embodiment 1

[0037] Corrosion of Weak Acid Hypochlorous Acid Disinfectant to Metal

[0038] According to the experimental method of "GBT 38498-2020 Disinfectant Metal Corrosion Evaluation Method", soak stainless steel, carbon steel, copper, aluminum and other metal sheets in hypochlorous acid disinfectant A with a concentration of 500ppm and add 10mg / L Soak in hypochlorous acid disinfectant B containing chloride, phosphate, nitrate, acetate or tartrate for 72 hours, change the solution once a day, rinse with clean water before and after soaking, and dry at 50°C for 1 hour. Weigh (accurate to 0.1 mg), calculate the corrosion rate, and the test results are shown in Table 1. Therefore, hypochlorous acid solution B added with 0.1mmol / L chloride, phosphate, nitrate, acetate or tartrate can effectively reduce the corrosion of hypochlorous acid to stainless steel, carbon steel, copper, aluminum and other metals .

Embodiment 2

[0042] Sterilization ability of weak acid hypochlorous acid disinfectant

[0043] According to "GB / T 38504-2020 Spray Disinfection Effect Evaluation Method", Appendix A "Laboratory Experiment Method for Surface Spray Disinfection Effect" uses 50ppm hypochlorous acid solution with a pH of 5.5 to treat Streptococcus, Bacillus subtilis, Candida, Aspergillus niger, Escherichia coli, Staphylococcus aureus, methicillin-resistant Staphylococcus aureus, Salmonella, and Pseudomonas aeruginosa were sprayed, and the number of colonies after contacting with hypochlorous acid solution for 1 minute, 3 minutes, and 5 minutes were detected (See Table 2 for details).

[0044] Bactericidal effect of table 2.50ppm hypochlorous acid disinfectant

[0045]

[0046] It can be seen that the bactericidal spectrum of hypochlorous acid solution is very wide, and it has a wide range of bactericidal capabilities against all microorganisms and viruses such as various bacteria, molds, yeasts, etc., espe...

Embodiment 3

[0048] Influence of Ultrasonic Parameters of Aerosol Generator on Concentration of Weak Acid Hypochlorous Acid

[0049] Using 35KHz, 40KHz, 53KHz, 1.7MHz to ultrasonically treat hypochlorous acid solutions with different concentrations, and detect the concentration changes (see Table 3 for specific results).

[0050] Table 3. The effect of different ultrasonic frequencies on the concentration of hypochlorous acid

[0051]

[0052]

[0053] Ultrasound has little effect on the stability of weakly acidic hypochlorous acid water. Within 3 hours of ultrasound at 35KHz~1.7MHz, the concentration loss of hypochlorous acid solution is less than 10%.

Abstract

The present invention relates to the field of disinfection, the invention relates to an integrated technology and method for dynamically disinfecting air in an aggregated place by using a weakly acidic hypochlorous acid disinfectant. The method comprises the following steps: injecting a weakly acidic hypochlorous acid disinfection solution into a disinfection machine to form aerosol for disinfection, wherein the pH value of the weakly acidic hypochlorous acid disinfection solution is 5.0-6.5, and the weakly acidic hypochlorous acid disinfection solution contains hypochlorous acid water with the concentration of 10-500ppm and sodium chloride with the concentration of 10-9000ppm; the disinfector is one or more of a wall-mounted disinfector, a movable disinfector, corridor type disinfection equipment and an intelligent disinfector; wherein the mist outlet amount of the sterilizer is 0.5-3.5 L / h. According to the method, aiming at different space sizes and different application scenes of crowd aggregation places such as schools, factories, office rooms, shopping malls, supermarkets and hospitals, a weakly acidic hypochlorous acid disinfectant air dynamic continuous disinfection technical specification is established, and aerosol generators suitable for different scenes are customized; and environmental disinfection can be carried out in the presence or absence of people.

Description

technical field [0001] The invention belongs to the technical field of disinfection, and in particular relates to an integrated technology and method for disinfection using weak acid hypochlorous acid disinfectant. Background technique [0002] Due to the impact of the epidemic, in order to ensure the development of the national economy, a safe working environment, and a stable social life, many government agencies, schools, enterprises, and supermarkets are facing the reality of returning to work and school. Once the resumption of work and school will inevitably lead to a large number of people gathering, the risk of cross-infection will be greatly increased. Therefore, the implementation of green and safe dynamic continuous disinfection of units, schools, enterprises, supermarkets and other crowd gathering places to kill bacteria and viruses in the air can effectively solve the current problems. [0003] At present, there are many methods for environmental disinfection (p...
