Abstract
An air pollution control apparatus 10 according to an embodiment of the present invention has a denitration catalyst layer 13 that removes NOx in flue gas 12, and atomizes HCl into the flue gas 12 to oxidize Hg, and also includes a swirling-flow generating member 30A that includes a swirling-flow generating-member body being partitioned to correspond to each passage of the denitration catalyst layer 13 and a plurality of swirling-flow generating vanes arranged on the partition inner walls to generate a turbulent flow, on an inlet 13a side of the denitration catalyst layer 13. With this configuration, a laminar flow of the flue gas 12 in a flue gas duct 19 is changed to a swirling flow, thereby enabling to increase a contact time between the flue gas 12 and a denitration catalyst and to improve the oxidation reaction efficiency between Hg in the flue gas 12 and the denitration catalyst.
