PROBLEM TO BE SOLVED: To provide a deodorization device which swiftly senses gas including odorous components exhausted from various generation sources at high concentration, without enlarging the device even if the generation amount is temporally varied, and capable of performing the removal of the odorous components low in the threshold of odorous strength stably at any time.SOLUTION: Provided is a deodorization device comprising: a box body 15 in which a gas inlet part 11 is provided on the uppermost stream side, a gas outlet part 12 is provided on the lowermost stream side, an openable/closable window 13 using a transparent member is fitted on the surface side, and a gas flow passage 14 connecting the gas inlet part 11 and the gas outlet part 12 is provided at the inside； and a deodorization filter 18 arranged at the inside of the gas flow passage 14 and provided with an upstream side treatment part 16 and a downstream side treatment part 17 bent at the central part and respectively tilted to the flowing direction of the gas. Further, the upstream side treatment part 16 and the downstream side treatment part 17 respectively have a flat net-shaped container 19 and granular treatment materials 20 which is stored the flat net-shaped container 19, capture te odorous components included in the passing gas, and decompose the same with a photocatalyst carried in the surface.SELECTED DRAWING: Figure 1【課題】種々の発生源から排出される臭気成分を高濃度で含むガスに対して、その発生量が時間的に変動しても装置の大型化を図らずに迅速に対応して、臭気強度の閾値が低い臭気成分の除去を常時安定して効率的に行うことが可能な脱臭装置を提供する。【解決手段】最上流側にガス入口部１１、最下流側にガス出口部１２を備え、表側に透明部材を用いた開閉可能な窓１３が取付けられ、内部にガス入口部１１とガス出口部１２をつなぐガス流路１４が設けられた箱体１５と、ガス流路１４内に配置され、中央部で折り曲げられてガスの流れ方向に対してそれぞれ傾斜する上流側処理部１６及び下流側処理部１７を備えた脱臭フィルター１８とを有し、更に、上流側処理部１６及び下流側処理部１７はそれぞれ、平形網状容器１９と、平形網状容器１９内に収納され、通過するガスに含まれる臭気成分を捕捉して表面に担持している光触媒によって分解する粒状処理材２０とを有する。【選択図】図１
