| 摘要 |
The present invention relates to an apparatus for catalytic cleaning, particularly de-nitrification, of waste gases, said apparatus comprising a heat exchanger ( 12 ) for exchanging heat between the already cleaned gas and the raw gas to be cleaned, a heating channel ( 14 ), in which additional heat is supplied to the raw gas and which joins the heat exchanger ( 12 ), a jetting unit is provided in the heating channel ( 14 ) for supplying ammonia and an arrangement of catalysts ( 16 ) containing catalysts, which is attached to the heating channel ( 14 ) and is placed above the heat exchanger ( 12 ), wherein the arrangement of catalysts ( 16 ) and the heating channel ( 14 ) are connected with each other via an essentially U-shaped deflection hood ( 24 ) and the heat exchanger is one of type working in counter flow.
