The invention relates to the field of flue gas treatment, in particular to an industrial flue gas desulfurization and denitrification equipment, including ammonia gas input pipe, blower, dust removal mechanism, screw conveyor, conveying mechanism, catalytic plate, chimney, treatment box and desulfurization Mechanism; the mixture of ammonia gas and air can be fed through the ammonia gas input pipe with the blower, which is convenient for removing the nitrate in the flue gas. The dust removal mechanism can remove the dust in the flue gas to avoid blocking the subsequent reactor and remove The dust is easy to push and output through the screw conveyor. The conveying mechanism realizes the transportation and mixing of the flue gas, which is convenient for its reaction and denitrification. The catalytic plate can strengthen the catalytic reaction, and the desulfurization mechanism realizes the removal of sulfur-containing substances in the flue gas. The flue gas desulfurization and denitrification equipment of the present invention installs the dust removal mechanism before the denitrification and desulfurization equipment to prevent dust from clogging the subsequent reaction vessel, which can make the internal gas mix more evenly and react more fully when in contact with the catalytic plate with a special structure.
