PURPOSE:To effectively utilize ozone harmful to human body and to efficiently decompose pollutants by decomposing the ozone generated with corona discharge by an ultraviolet ray lamp and ozone decomposing catalyst. CONSTITUTION:Comparatively large-sized dusts are removed from the air taken into the device 10 from the outside by a fan 25 through a dust collecting part A disposed with discharge electrodes 14 and counter electrodes 16. In this case, ozone is simultaneously generated from the oxygen in the air by the corona discharge, and this ozone decomposes a part of pollutants in the air from the outside. The mixture gas contg. ozone is sucked into a deodorizing part B where the ozone is decomposed into oxygen O2 and highly activated nascent state oxygen O by irradiation of ultraviolet ray lamp 18 generating ultraviolet rays of chiefly 25.4nm wave-length. Then, the ozone is similarly decomposed into O2 and O through a porous ozone decomposing catalyst layer 20, and this nascent state O instantly decomposes the pollutants. |
