| 摘要 |
A plant comprising a post combustion chamber (1) connected to the combustion chamber of a household rubbish incineration furnace whose hot gases it uses in order, by means of suitable burners (2, 3), to heat sewage sludges and industrial liquids and a circuit for the treatment of the smoke and residues coming from said post combustion. This circuit, which is held under vacuum by a blower (27), comprises a dry cooling tower (7) employing semi-liquid sludges as cooling agent, an absorption tower (15) employing a solution adapted to combine the predominantly acid gases of the smoke, and a separating tower (22) in which the liquids in suspension are removed. A recycle circuit (190) for the solution and liquid separated and means of recovering metallic particles and compounds (10, 12, 29) complete this plant. |
