Abstract

L'invention concerne un système de désinfection et de stérilisation et un procédé de stérilisation. Le système de désinfection et de stérilisation est basé sur un appareil de génération de gaz de stérilisation (11). L'appareil de génération de gaz de stérilisation (11) comprend une partie de génération de radicaux hydroxyle, une partie de mélange et une partie d'activation. Une vapeur de radicaux hydroxyle générée dans la partie de génération de radicaux hydroxyle est introduite dans la partie de mélange, puis mélangée avec de l'ozone. La partie de mélange est en communication avec la partie d'activation, de sorte que la vapeur mélangée est ensuite introduite dans la partie d'activation. Une première lampe à ultraviolets (6) utilisée pour exciter et/ou dégrader l'ozone est disposée à l'intérieur de la partie d'activation. L'appareil de génération de gaz de stérilisation (11) est combiné à d'autres appareils et appliqué dans divers scénarios d'application différents pour désinfecter et stériliser l'environnement et le corps humain. L'utilisation du mélange d'ozone et d'un radical hydroxyle pour la stérilisation fournit non seulement une forte capacité d'oxydation et un puissant effet de stérilisation, mais est également respectueuse de l'environnement et des matériaux, évite la génération de pollution secondaire et d'effets indésirables, et est applicable à grande échelle.
