Hydrogen peroxide steam sterilizing device

Abstract

The invention discloses a hydrogen peroxide steam sterilizing device which comprises a hydrogen peroxide vaporization system, a hydrogen peroxide steam circulation diffusion system, a hydrogen peroxide steam circulation absorption and decomposition system, and a sterilizing space environmental parameter monitoring system. Through the adoption of a multi-channel flashed heating way, hydrogen peroxide solution is uniformly dripped on a vaporization disc to achieve instant vaporization, and steam is quickly taken out of a vaporizer by vortex-airflow of a fan, and enters into a round jet apparatus, so that excessive heating of hydrogen peroxide and drop existence are avoided. The round jet apparatus is provided with a plurality of jet orifices and a rectifying device to quickly and uniformly diffuse the hydrogen peroxide steam to all corners of a sterilizing space. The hydrogen peroxide steam sterilizing device can quickly and controllably produce real hydrogen peroxide steam, and can quickly and uniformly diffuse the hydrogen peroxide steam.

Description

technical field [0001] The invention relates to the field of microbial sterilization, and more specifically relates to a device for sterilizing spaces and objects in operating rooms, biosafety laboratories, and pharmaceutical workshops by using hydrogen peroxide vapor to kill microorganisms. Background technique [0002] At present, domestic operating rooms, biosafety laboratories, and pharmaceutical workshops are sterilized using traditional sterilization methods, and there are generally incomplete sterilization, sterilization dead ends, or long sterilization cycles, low efficiency, or sterilant residues. Serious, serious hazards to personnel and the environment. [0003] The bactericidal performance of liquid hydrogen peroxide has been recognized for more than 100 years, and it has the characteristics of environmental protection and high efficiency. However, liquid hydrogen peroxide requires very high concentrations and long contact times to be sporicidal. Later, it was ...

AI Technical Summary

Problems solved by technology

However, the micropores cannot quickly and completely eject the vaporized hydrogen peroxide, and it is easy to cause the hydrogen peroxide to decompose by overheating inside.

[0005] Hydrogen peroxide vaporization is also a condensation process during the spatial diffusion process. If the diffusion is not rapid and timely, it will lead to unsatisfactory spatial mixing and diffusion effects. Hydrogen peroxide steam sterilization equipment generally has inconsistent spatial sterilization effects and penetrates porous objects. poor sex problem

The hydrogen peroxide steam sterilization device described in utility model patent 200920031190.8, although it can accurately control the vaporization amount of hydrogen peroxide, does not have a device and method for rapid and uniform diffusion of hydrogen peroxide vapor

[0006] In addition, after hydrogen peroxide vapor sterilization, it cannot be directly discharged into the atmosphere and needs to be treated safely. However, neither of the two patents cited above provides a post-treatment method for hydrogen peroxide vapor

Although the patent CN 200957200Y mentions a hydrogen peroxide vapor catalyst, it needs to be dehumidified with a drier after catalytic decomposition, which increases the operating cost of hydrogen peroxide vapor sterilization
