DESULFURIZATION AND DENITRATION DEVICE HAVING HIGH-EFFICIENCY DENITRATION

摘要

A desulfurization and denitration device that has high-efficiency denitration, the device comprising: an adsorption tower (1), an analytical tower (2), a gas mixer (3), a first activated carbon conveyor (4), a second activated carbon conveyor (5) and an activated carbon material bin (AC) disposed above the adsorption tower (1), wherein the adsorption tower (1) is provided with a flue gas inlet (A) at one side thereof, and is provided with a flue gas outlet (B) at the other side thereof; a first gas pipe (L1) leading out from a gas outlet of the gas mixer (3) is connected to a gas inlet of the activated carbon material bin (AC), a second gas pipe (L2) leading out from the gas outlet of the gas mixer (3) is connected to the flue gas inlet (A), and a third gas pipe (L3) leading out from a gas outlet of the activated carbon material bin (AC) merges with the second gas pipe (L2). The present application adopts activated carbon to pre-adsorb a portion of ammonia; and at the same time, in order to enhance the denitration effect, a portion of ammonia is re-injected in the middle of the adsorption tower.
