Title:
OPTICAL DEODORIZATION DEVICE AND OPTICAL DEODORIZATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/082703
Kind Code:
A1
Abstract:
Disclosed is an optical deodorization device with which the harmful effects of ozone on an organism such as an animal are reduced and bad odors within a treatment room are eliminated even if the organism is present in the treatment room. An optical deodorization device (100) projects ultraviolet rays into a gas to be treated containing bad-odor causing substances so as to eliminate the bad-odor causing substances. The optical deodorization device (100) comprises: a first light source that emits vacuum ultraviolet light (VUV light); and a second light source that emits deep ultraviolet light (DUV light) which does not include vacuum ultraviolet light. The first light source and the second light source are disposed so that at least a portion of an outside space, which is outside of a generation space where singlet oxygen atoms (O(1D)) that break down the bad-odor causing substances are generated by light emitted from the first light source and which is spatially connected to the generation space, is included in an arrival space where light emitted from the second light source arrives.
