<p>PURPOSE:To secure deodorizing and deoiling effect and to arrest the noise by decreasing the air-flow resistance insofar as possible by meandering an air passage between the separated and opposed side walls in the air flow direction so that the specified width is provided with a continuous circular line as the center. CONSTITUTION:The side wall 5 of each block 5 is meandered in its longitudinal direction, and the side walls 6 are separated and opposed to form a meandering air passage 7 in specified width. At this time, the center line 10 of the passage 7 is circular and continuous. In this case, the parallel straight lines X1 and X2 in the air flow direction at a distance A apart cross the straight lines Y1, Y2, Y3,...Yn orthogonal to the former straight line at a distance B away from one another, circles 9,... of diameter R are positioned with the centers alternately on the intersections on the straight lines X1 and X2 to satisfy R>A>R/2 and B = Root ¦R<2>-A<2>¦, and the adjacent circles 9 and 9 are connected at the contact. Consequently, the adsorption area is increased, and the air-flow resistance is decreased insofar as possible.</p> |
