Abstract

The invention relates to an energy-saving desulfuration and denitrification dust collector, particularly to an energy-saving desulfuration and denitrification dust collector for a large boiler, aiming at solving the problems that the existing boiler is low in efficiency, the environment in a boiler room is seriously polluted, the efficiency of the desulfuration and denitrification dust collector is low, and the body health of workers is affected. According to the invention, a waste heat boiler of each desulfuration dedusting assembly is connected with a boiler smoke outlet of a chain grate stoker hot water boiler with a longitudinal boiler barrel, the waste heat boiler is communicated with an air preheater, a first desulfuration chamber is connected with an exhaust opening of an air blower, the smoke outlet of the waste heat boiler is connected with an anti-explosion bypass flue and a wet-method desulphurization dust collector assembly, each swirling water membrane desulfuration and denitrification dedusting tower is connected with a swirling water membrane desulfuration dedusting auxiliary tower, and each swirling water membrane desulfuration dedusting auxiliary tower is connected with a chimney bridge by a third air inducing flue. The energy-saving desulfuration and denitrification dust collector is used for desulfuration and denitrification and dedusting of large boilers.

Description

technical field [0001] The invention relates to an energy-saving desulfurization, denitration and dust removal device, in particular to an energy-saving desulfurization, denitration and dust removal device for a large boiler. Background technique [0002] The thermal efficiency of the existing boiler is not high, and there is no explosion-proof bypass flue in the boiler room, which has potential safety hazards and serious environmental pollution, which affects the health of workers; ceramic multi-tube dust collectors are generally used for desulfurization and dust removal, and the dust collector occupies an area of The area is large. Because the cyclone on the ceramic multi-tube dust collector is ceramic, the ceramic is fragile and needs to be replaced frequently. Large bag dust removal and electric dust removal consume a lot of power, the dust removal efficiency is not high, and they cannot desulfurize. The emissions of sulfur dioxide and nitrogen oxides are high, and the ...
