Abstract
The invention relates to a filtering device for multiply polluted gasses, with an inclined bed with a filling of catalytic material, which bed has a retaining wall at its lower longer side, with a clean-gas exit positioned in the area of one front side of the bed, which ejects the gas which has passed through the filling, and with a flush-gas entrance also positioned in the area of one front side of the bed, the flush-gas entrance (40) and the clean-gas exit (36) being provided at the same front side (38), and beneath the bed (12), current-influencing devices (50) being positioned spread between the two front sides, which devices prevent or at least reduce current peaks in the flow of flush gas through the bed (12).
Claims22
Filtering device for multiply polluted gasses, with an inclined bed with a filling of catalytic material, which bed has a retaining wall at its lower longer side, with a clean-gas exit positioned in the area of one front side of the bed which ejects the gas which has passed through the filling, and with a flush-gas entrance also positioned in the area of one front side of the bed, characterized in that beneath the bed, current-influencing devices are positioned spread between the two front sides, which devices prevent or at least reduce current peaks in the flow of flush gas through the bed, and in that the flush-gas entrance and the clean-gas exit are provided at the same front side.
Filtering device in accordance with 1, characterized in that the catalytic material also filters out sulfur and/or compound of sulfur and that the compression layer, which slides down via the lower longer side of the bed, will fall from a filter box of the filtering device into the area of a conveyor device, in particular a conveyor screw.
