<P>PROBLEM TO BE SOLVED: To provide a photocatalyst system which allows easy maintenance operations, e.g., checking, cleaning and replacement of the photocatalyst filter and light source even when a photocatalyst filter unit and a light source unit are large and is easy in structure and attainable at low costs. <P>SOLUTION: In the system are disposed photocatalyst filters 30, two or more nearly flat photocatalyst filter modules 20 including a black light 27 activating the photocatalyst filters 30, a photocatalyst filter module group 20B arranged so as to be almost perpendicular to the direction of the gas flow and adjacent to each other and a module holding structures(12, 24) holding the modules 20 of the photocatalyst filter module group 20B so as to allow independent translation of the modules 20 in the direction of the gas flow. A standby space S1 is formed on the side of the gas introduction end or the gas discharge end of the module group 20B. A space S2 for maintenance is formed by translating the modules 20 appropriately to the standby space S1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
