Abstract

A process for purifying the exhaust gases from industrial furnaces and especially from waste incineration plants is described in which process the exhaust gases which contain acid, neutral and/or basic pollutants in the gaseous or solid form or in the form of a mist, are treated in an evaporative cooler 1 and then in a dry purifier 2, in which they are freed from at least a substantial portion of the solid pollutants, are finally in a scrubber 3 by means of a wash liquid. The temperature of the exhaust gases in the evaporative cooler is kept above the dew point, and the wash liquid in the scrubber is cycled through a sludge separator 4, from which the suspension or solution of pollutants is withdrawn and fed into the evaporative cooler and mixed in a mixing space in the latter with the hot exhaust gases. Those walls of the evaporative cooler which come into contact with the mixture of exhaust gases and recycled suspension or solution of pollutants and which consist of a material that can be corroded by the said mixture at room temperature are heated to a temperature above the dew point. There is also described a sludge separator for use in such a process. <IMAGE>
