Title:
DISINFECTION AND STERILIZATION SYSTEM AND STERILIZATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/170029
Kind Code:
A1
Abstract:
A disinfection and sterilization system and a sterilization method. The disinfection and sterilization system is based on a sterilization gas generating apparatus (11). The sterilization gas generating apparatus (11) comprises a hydroxyl radical generating part, a mixing part, and an enhancing part. Hydroxyl radical mist generated in the hydroxyl radical generating part is introduced into the mixing part and then mixed with ozone. The mixing part is in communication with the enhancing part so that the mixed mist is further introduced into the enhancing part. A first ultraviolet lamp (6) used for exciting and/or degrading ozone is provided within the enhancing part. The sterilization gas generating apparatus (11) is combined with other apparatus and applied in various different application scenarios for disinfecting and sterilizing the environment and human body. The employment of the mixture of ozone and a hydroxyl radical for sterilization not only provides strong oxidation capability and a great sterilization effect, but also is environmentally and physically friendly, avoids the generation of secondary pollution and side effects, and is broadly applicable.
