ABSTRACT:
The present invention pertains to a device for removing toxic substances, e.g., dioxins and furans, from flue gases, e.g., a refuse incinerator plant, prior to entry into the smokestack. To adsorb these toxic aromatic substances, activated carbon is mixed with 30-40 vol. % water in a filter vessel, and the flue gases in the form of chains of fine bubbles are passed through the activated carbon-water mixture. The filter vessel 1 has a perforated partition 13 acting as a gas distributor. The activated carbon sludge saturated with toxic substances is drawn off and replaced by correspondingly adding dry activated carbon and water.
