FIELD: energy.SUBSTANCE: invention relates to heat engineering, more precisely to a device for cleaning flue gases from nitrogen oxides by selective non-metallic reduction. Device includes a flue pipe housing, inside which there is a distribution grid for introduction of ammonia solution inside gas stream of flue gas. Distribution grid is made of rotary segments and is kinematically connected with control unit. Rotary segments are arranged between two circular diaphragms, from which one is tightly connected with chamber for collection o ammonia solution and housing, and other with a guide diffuser. Before flue gas outlet pipe there is an additional cone, conjugated geometrically with guide diffuser and connected with device for movement thereof.EFFECT: disclosed device provides higher degree of purification of flue gases from nitrogen oxides, is easy to manufacture and reliable in operation.5 cl, 3 dwg |
