Abstract:
1. An air pollution control apparatus having at least one denitration catalyst layer that removes nitrogen oxides in flue gas from a boiler and atomizes hydrogen chloride into a flue gas duct of the flue gas to oxidize mercury, wherein a swirling-flow generating member is provided at an inlet of the denitration catalyst layer to change a laminar flow of flue gas in a flue gas duct to a swirling flow inside the denitration catalyst layer, wherein the denitration catalyst layer is a honeycomb catalyst, and the swirling-flow generating member includes a swirling-flow generating-member body being partitioned to correspond to each passage at an inlet of the honeycomb catalyst, and a plurality of swirling-flow generating vanes arranged on the partition inner walls to generate a turbulent flow.
