Fumigating disinfection method for indoor environment

Abstract

The invention discloses a fumigating disinfection method for indoor environment. The fumigating disinfection method comprises the following steps: designing disinfection space volume of a single disinfection apparatus, determining the quantity and position of the disinfection apparatus required by the disinfection space, charging alcohol and paraformaldehyde in each disinfection apparatus, all the disinfection apparatus are ignited by grouping, then go out of the disinfection space and seals the disinfection space, and ventilation is carried out for the disinfection space, wherein, the time from ignition of the first disinfection apparatus by all groups to exit of the disinfection space by all workers is shorter than the time from ignition of the first disinfection apparatus by all groups to volatilization of paraformaldehyde in the disinfection apparatus. The fumigating disinfection method is suitable for fumigating disinfection of enclosed spaces with different sizes, and has the advantages of safety and non corrosion of the disinfection apparatus.

Description

technical field [0001] The invention relates to a disinfection method, in particular to a method for fumigation and disinfection of an indoor environment. Background technique [0002] Fumigation and disinfection technology is a technical measure to convert disinfectants such as peracetic acid and formaldehyde into a gaseous state by heating and other methods, and volatilize into a closed place to kill pests, pathogenic microorganisms or other harmful organisms. The biggest advantage of fumigation and disinfection is that the fumigation medicine can be evenly distributed to every corner of the indoor environment. The disinfection is comprehensive and thorough and saves trouble and effort. It is especially suitable for the disinfection of indoor air pollution. It is widely used in biological and medical laboratories, slaughterhouses, farms, etc. . There are two commonly used fumigation methods. One is formalin+potassium permanganate fumigation and disinfection method. This ...

Problems solved by technology

[0003] Both of the above two disinfection methods have shortcomings, which restrict their application in production practice.

Formalin+potassium permanganate fumigation is suitable for disinfection in small spaces, but not suitable for large spaces such as livestock and poultry pens in farms. The reason is that the reaction of formalin+potassium permanganate fumigation is once At the beginning, formaldehyde volatilized rapidly, filling the entire space, the reaction speed could not be controlled, and the personnel had no time to evacuate

The peracetic acid used in the peracetic acid fumigation method must be prepared immediately because it is easy to decompose. Two solutions of peracetic acid are prepared, one is hydrogen peroxide + concentrated sulfuric acid, and the other is glacial acetic acid. When the liquid is mixed, it is easy to splash and explode, and the operation is more dangerous. In addition, peracetic acid is corrosive. Frequent use of this method will cause the metal disinfection device to oxidize and rust
