DISCLOSED FOR PURIFYING EXHAUST GASES, IN PARTICULAR THOSE FROM WASTE-INCINERATION PLANTS

摘要

Method for cleaning exhaust gases (1) from waste incineration plants, in particular household waste incineration plants (2), wherein the exhaust gases (1) are dusted, conditioned and led through an adsorber (6) filled with active coke (7) to remove harmful substances. The uncleaned exhaust gases (1) are guided through the adsorber (6). The adsorption is controlled in such a way that the gas (8) leaving the adsorber is almost free of SO2. Uncleaned gas (8) leaving the adsorber (6) is drawn from HCl and HF for the manufacture of reusable products, in particular hydrochloric acid and / or NaCl. Through multiple adsorption (6, 14, 25, 36) and regeneration (20, 29), on the one hand the exhaust gases (1) are purified, and on the other hand harmful substances are separated from the gases burnt (1) and processed into salable products.
