Abstract
An air pollution control apparatusaccording to an embodiment of the present invention has a denitration catalyst layerthat removes NOx in flue gas, and atomizes HCl into the flue gasto oxidize Hg, and also includes a swirling-flow generating memberA that includes a swirling-flow generating-member body being partitioned to correspond to each passage of the denitration catalyst layerand a plurality of swirling-flow generating vanes arranged on the partition inner walls to generate a turbulent flow, on an inletside of the denitration catalyst layer. With this configuration, a laminar flow of the flue gasin a flue gas ductis changed to a swirling flow, thereby enabling to increase a contact time between the flue gasand a denitration catalyst and to improve the oxidation reaction efficiency between Hg in the flue gasand the denitration catalyst.
