PROBLEM TO BE SOLVED: To provide a gas cleaning device capable of efficiently treating gas by effectively using the light irradiated from an ultraviolet lump and also increasing the contact of gas and a photocatalyst at the time of removing a harmful material in the air by using the photocatalyst. SOLUTION: In the device for cleaning the gas by introducing the gas into a system and irradiating ultraviolet rays to a photocatalyst sheet, the photocatalyst sheet is disposed in a gas flowing passage so as to cross in the gas flow direction so that gas flow may be formed along the surface of the photocatalyst sheet. |
