Photocatalytic reaction device

摘要

An intake port ( 2 ) is formed in a casing ( 1 ), a plurality of discharge ports ( 3 ) are formed in a side face of the casing ( 1 ) different from this intake port ( 2 ), or are arranged continuously along the entire circumferential surface of the side face of the casing 1 . A series of vanes ( 5 ) of a centrifugal type blower ( 4 ) for feeding air flowing in from the intake port 2 to the discharge ports ( 3 ) are arranged around the intake port ( 2 ) within the casing ( 1 ) and a photocatalyst carrier ( 6 ) that carries photocatalyst is arranged at the outer periphery of the series of vanes ( 5 ) of this centrifugal type blower ( 4 ). By thus providing a plurality of discharge ports ( 3 ) or providing discharge ports along the entire circumferential surface of the side face of the casing ( 1 ), the area of the flow path to the discharge ports ( 3 ) is increased compared with the conventional case, in which only a single discharge port is provided, and a higher decomposition treatment capability in respect of impurities in the air is displayed than in the conventional case.
