Integrated flue gas dust removal desulfurization and denitrification device

Abstract

The invention provides an integrated flue gas dust removal desulfurization and denitrification device. The novel integrated high-efficiency flue gas desulfurization and denitrification device comprises a flue gas input pipeline, an electric bag precipitator, a desulfurization and denitrification tower, an ammonia water supply pump and a denitrfying agent supply system, wherein the flue gas input pipeline is connected with the inlet of the electric bag precipitator; the flue gas outlet of the electric bag precipitator is connected with the flue gas inlet of a front catalytic oxidizer in the desulfurization and denitrification tower; the ammonia water supply pump is connected with a slurry circulating pool at the bottom of the desulfurization and denitrification tower; and a denitrfying agent outlet of a denitrfying agent storage tank in the denitrfying agent supply system is communicated with a denitrfying agent inlet and a denitrfying agent injection net of the front catalytic oxidizer in the desulfurization and denitrification tower. According to the device, the flue gas generated by an industrial coal system can be effectively subjected to flue gas electric bag precipitation, wet ammonia process and desulfurizing agent oxidation denitrification.

Description

technical field [0001] The invention relates to a flue gas purification treatment device, in particular to an integrated flue gas dust removal, desulfurization and denitrification device. Background technique [0002] Since my country is a country with more coal and less oil, the primary energy structure will still be dominated by coal in the short term. The sulfur oxides and nitrogen oxides produced by industrial coal will cause serious pollution to the environment and endanger human health. Dealing with sulfur oxides and nitrogen oxides produced by industrial coal has always been the key to environmental governance in my country. [0003] When dealing with sulfur oxides and nitrogen oxides produced by industrial coal, flue gas dust removal is the first hurdle for flue gas purification. Traditional flue gas dust removal generally uses a combination of cyclone and bag dust removal, but due to dust removal The equipment has defects such as large resistance during operation, w...
