Plasma pulverization sterilizing method

Abstract

The invention discloses a plasma pulverization sterilizing method and application thereof. The plasma pulverization sterilizing method comprises the following steps: S1, carrying out atomization treatment on a hydrogen peroxide solution with the concentration smaller than 8% to form hydrogen peroxide aerosol; S2, ionizing the hydrogen peroxide aerosol to generate active ion hydrogen peroxide aerosol containing high-concentration reactive oxygen species; S3, deflecting the active ion hydrogen peroxide aerosol subjected to ionization atomization after the active ion hydrogen peroxide aerosol passes through a deflection magnetic field; and S4, rapidly diffusing the high-concentration reactive oxygen species in a space after the high-concentration reactive oxygen species passes through the deflection magnetic field so that the high-concentration reactive oxygen species are adsorbed on the surface of rooms or articles with negative charges for oriented sterilizing. According to the plasma pulverization sterilizing method, hydrogen peroxide molecules are split through arcs, the active ion hydrogen peroxide aerosol containing the high-concentration reactive oxygen species is generated, and thus, organic living bodies such as bacteria including inactivated viruses, bacterial spores and mycotic spores are killed.

Description

technical field [0001] The invention relates to the field of disinfection, in particular to a plasma atomization disinfection method. Background technique [0002] At present, the commonly used methods for biological purification of clean areas such as production and laboratories include: formaldehyde fumigation, peracetic acid, vaporized hydrogen peroxide, and sporicide wiping. However, there are a lot of deficiencies in the existing technologies in various aspects. Although the effect of formaldehyde fumigation can meet the requirements, it has been strictly prohibited in Europe and the United States due to its long cycle period, hazards to personnel (highly carcinogenic substances) and other reasons. For the disinfection and sterilization of space, formaldehyde is gradually being abandoned with the improvement of industry standards and awareness in our country. Gasified hydrogen peroxide (high-temperature dissociated hydrogen peroxide liquid to form perhydroxyl) has been...

However, there are a lot of deficiencies in the existing technologies in various aspects. Although the effect of formaldehyde fumigation can meet the requirements, it has been strictly prohibited in Europe and the United States due to its long cycle period, hazards to personnel (highly carcinogenic substances) and other reasons. For the disinfection and sterilization of space, formaldehyde is gradually being abandoned with the improvement of industry standards and awareness in our country

Gasified hydrogen peroxide (high-temperature dissociated hydrogen peroxide liquid to form perhydroxyl) has been gradually promoted in China because of its broad-spectrum bactericidal properties, low cost of use, and no residual hazards. However, in the process of promotion, people Also gradually realized the shortcomings: for example, the disinfection time is long, the disinfection environment needs to be airtight, and there is no specific setting for specific needs of disinfection
