CHLORINE DIOXIDE GAS TREATMENT STRUCTURE, CHLORINE DIOXIDE GAS TREATMENT DEVICE, STERILIZATION DEVICE, AND ENVIRONMENT CLEANING DEVICE

摘要

[Problem] A long period of time is necessary to reduce the concentration of chlorine dioxide gas that is used to clean the surrounding environment to a level that is safe for humans. [Solution] A chlorine dioxide gas treatment structure (20) that reduces the chlorine dioxide gas within air to be treated that contains chlorine dioxide gas, and that is provided with: a space in which the air to be treated is circulated; a fan (23); a contact layer; and an ultraviolet light irradiation means. The contact layer comprises steel wool (21) that is moistened with water and in which fine iron wires are gathered together in a cotton-like state. The fan (23) causes the air to be treated to circulate within the space, and the air to be treated is brought into contact with the contact layer in a state in which the contact layer is irradiated with ultraviolet light by the ultraviolet light irradiation means (24) in the circulation path.
