Low-consumption carbon-based catalytic desulfurization and denitrification device for flue gas purification

Abstract

The invention discloses a low-consumption carbon-based catalytic desulfurization and denitrification device for flue gas purification and belongs to the technical field of flue gas purification. The device includes a treatment box, wherein a baffle is fixedly connected to the inner side of the treatment box; the treatment box is provided with a desulfurization and denitrification chamber and a purification chamber on two sides of the baffle; a carbon-based catalyst and ammonia gas are introduced into the desulfurization and denitrification chamber at the same time, so that flue gas is synchronously desulfurized and denitrified; meanwhile, the turbulent flow of the flue gas is remarkably improved through spoilers; the residence time of the flue gas in a room is prolonged; ammonia gas and flue gas are fully and uniformly mixed; the desulfurized and denitrified flue gas enters a flue gas filter through a flue gas inlet pipeline to be filtered; and after the filtering is finished, the fluegas is discharged after being filtered by a filter plate, thus completing the desulfurization and denitrification and gas purification thoroughly; further, a flue gas detector can detect whether theflue gas reaches the standard or not, if the flue gas does not reach the standard, the flue gas can enter the desulfurization and denitrification chamber again through the guide pipe to react, the desulfurization and denitrification work and the purification work are completed in the same device, energy consumption is reduced, and meanwhile the purification cost is saved.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, in particular to a low-consumption carbon-based catalytic desulfurization and denitrification device for flue gas purification. Background technique [0002] The flue gas combined desulfurization and flue gas pollutant control technology using carbon-based catalysts as adsorbents and catalysts can realize the integration of desulfurization, denitrification, mercury removal, heavy metal removal, and dust removal, and eliminate white smoke. This technology basically does not consume water and saves a lot of water resources. The by-product of desulfurization is high-concentration SO2, which is convenient for resource utilization. It belongs to deep purification technology and is a new generation of flue gas pollutant control technology with obvious advantages. It has great application prospects in many fields such as smelting and waste incineration. [0003] The principle of carbon-ba...
