Intelligent direct-injection hydrogen peroxide gas sterilizer

Abstract

The invention discloses an intelligent direct-injection hydrogen peroxide gas sterilizer which comprises a frame. A drainage fan is fixedly mounted on the upper side of a bottom plate of the frame, and a gas purifier is arranged on the outer side of the drainage fan. A hydrogen peroxide solution is utilized to output pure hydrogen peroxide gas by maximum flow that flashing technology can bear; after a system monitors the process when generated damp-hot hydrogen peroxide gas is sprayed from a diffusion mechanism into a to-be-sterilized space, the system withdraws cold air containing the hydrogen peroxide gas from the inside of a room, reheats, mixes with newly generated high-concentration hydrogen peroxide gas, re-sprays into the room and repeats in this way until the hydrogen peroxide solution in a fixed amount acquired by calculation becomes gas completely gas which is diffused into the room. The hydrogen peroxide gas forms a micro condensing film on any surface that it can touch.

Description

technical field [0001] The invention relates to a relatively large range, in particular to an intelligent direct-injection hydrogen peroxide gas sterilizer. Background technique [0002] The sterilizer is saturated steam sterilization, which is a commonly used physical method to kill organisms, because high temperature has obvious lethal effect on bacteria; high temperature denatures and coagulates the bacteria, and loses the activity of enzymes, thus killing the bacteria; the thermal sterilization chamber is the most Reliable, the most mature and commonly used sterilization method, there are usually two methods of moist heat sterilization and dry heat sterilization. [0003] For the sterilization of equipment or small confined spaces, there are currently many so-called "hydrogen peroxide dry fog sterilizers" in China, which use high-speed airflow to blow liquid hydrogen peroxide into the equipment or small closed spaces to be sterilized. In the space, a sterilizer that use...

Problems solved by technology

[0003] For the sterilization of equipment or small confined spaces, there are currently many so-called "hydrogen peroxide dry fog sterilizers" in China, which use high-speed airflow to blow liquid hydrogen peroxide into the equipment or small closed spaces to be sterilized. In the space, a sterilizer that uses the strong oxidation ability of hydrogen peroxide to inactivate microorganisms in the space; its sterilization efficiency can generally only reach the 3Log level, and it is difficult to verify the repeatability and reliability
