ABSTRACT:
A filter for separating pollutants from flue gases with a filter housing and with a plurality of filter boxes arranged therein at spaced locations horizontally one on top of another or vertically next to one another. These filter boxes contain the filter medium, which may be activated carbon, open-hearth furnace coke or a similar material. The filter boxes are sprayed with water via nozzles. The sprayed surfaces of the filter boxes are correspondingly designed as surfaces permeable to water. Flue gases flow into the filter boxes from the bottom. These surfaces of the filter boxes are correspondingly permeable to gas. A water collection box with vertical gas flow pipes, from which the collected water is pumped off and reused for spraying with water, is located under the filter boxes.
