Description

Technical Field

[0001] The utility model relates to the technical field of sterilizers, in particular to a hydrogen peroxide sterilizer for gasifying disinfectant. Background Art

[0002] Gasified hydrogen peroxide is also called gasified hydrogen peroxide. Gasified hydrogen peroxide sterilization is a technology that uses the advantage of hydrogen peroxide in gas state to kill bacterial spores more than in liquid state to achieve the requirement of complete sterilization. It is often used for sterilization in confined spaces such as isolation rooms and isolators. During the disinfection and sterilization process, gasified hydrogen peroxide is reduced to water and oxygen. Compared with other sterilization methods, it has no harmful residues and is harmless to operators and the environment. In conventional gasification, hydrogen peroxide is usually gasified by heating and evaporation. Since liquid hydrogen peroxide will reduce the temperature of the surface of the heating equipment when it drips on the heating equipment, the temperature of the heating equipment needs to be increased to a certain extent during continuous evaporation. However, too high a heating equipment temperature will prevent the liquid hydrogen peroxide from evaporating quickly due to the Leidenfrost effect when it drips, thereby reducing the gasification efficiency of the liquid hydrogen peroxide.
