PURPOSE:To generate a gas-liquid contact effectively and to realize a deodorization work efficiently by making the flow of a bad smell air passing through a filter in a turbulant flow constantly. CONSTITUTION:Numerous corrugated cardboards 2 are laminated to line up all the penetrating holes 2a which are composed of cores 2b of corrugated paper in the same direction, to compose a filter layer-form member 3 in a block-form. Such filter layer members 3 are superposed to make the penetrating holes 2a in the same direction to compose a filter 1. When the filter layer member 3 are superposed, they are turned over alternately to superpose to contact the front surfaces and the rear surfaces each other. As a result, the group of the penetration small holes 2a are combined by slipping the positions of the small holes. |
