Ionized hydrogen peroxide comprehensive plasma sterilization technology

Abstract

The invention discloses an ionized hydrogen peroxide comprehensive plasma sterilization technology (normal temperature and pressure dissociation technology), and relates to the technical field of sterilization. Equipment used in the ionized hydrogen peroxide comprehensive plasma sterilization technology mainly comprises a machine and a control system, wherein the machine mainly comprises a sterilizing agent conveying system, a carrier gas conveying treatment system and a plasma generation module. The ionized hydrogen peroxide comprehensive plasma sterilization technology is used for solving the problems of long formaldehyde fumigation time and harm of residues to human bodies and meanwhile solving the problems that a gasified hydrogen peroxide sterilizer (high-temperature dissociation technology) needs to perform turbulence on sterilization environments, and otherwise, the problems of slow gas diffusion, sterilization dead angles and high requirements on environment temperature and humidity exist (the requirements on environments, facilities and the level of operators are high). The equipment for realizing biological purification through the ionized hydrogen peroxide comprehensive plasma sterilization technology has the advantages of small size, low energy consumption, low requirements on space, small corrosivity, relatively fast sterilization speed and good sterilization effect.

Description

technical field [0001] The invention relates to the field of sterilization technology, in particular to a comprehensive plasma sterilization technology of ionized hydrogen peroxide. Background technique [0002] At present, Chinese pharmaceutical companies generally use formaldehyde fumigation methods to carry out biological purification of clean areas such as production and laboratories, such as: formaldehyde fumigation, peracetic acid, vaporized hydrogen peroxide, sporicide wiping, etc. However, there are a lot of deficiencies in the existing technologies in various aspects. Formaldehyde fumigation, although the effect can meet the requirements, but its long cycle, hazards to personnel (high carcinogenic substances) and other reasons have been strictly prohibited in Europe and the United States. For the disinfection and sterilization of space, with the improvement of standards and awareness of China's pharmaceutical industry and pharmaceutical equipment industry, formalde...

Problems solved by technology

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, with the improvement of standards and awareness of China's pharmaceutical industry and pharmaceutical equipment industry, formaldehyde is gradually being abandoned

Vaporized hydrogen peroxide (dissociated hydrogen peroxide liquid at high temperature to form perhydroxyl) has been gradually promoted in China due to its broad-spectrum bactericidal properties, low cost of use, and no residual hazards. However, in the process of promotion, people I also gradually realized the shortcomings: such as high equipment cost, large equipment volume, high requirements for air conditioning systems, customer site infrastructure and equipment, and a large number of turbulence auxiliary equipment, as well as a large number of corrosive cases. Limit the implementation of vaporized hydrogen peroxide sterilization technology
