Desulfurization and denitrification equipment with high denitrification efficiency

摘要

As a desulfurization and denitrification apparatus having high efficiency denitrification, the adsorption tower (1), analysis tower (2), gas mixer (3), the first activated carbon conveyor (4), the second activated carbon conveyor (5) and the adsorption tower (1) It includes an activated carbon material container (AC), wherein the adsorption tower (1) is provided with a flue gas inlet (A) on one side and a flue gas outlet (B) on the other side; The first gas pipe L1 from the gas outlet of the gas mixer 3 is connected to the gas inlet of the activated carbon material container AC, and the second gas pipe L2 from the gas outlet of the gas mixer 3 is flue. An apparatus is provided in which a third gas pipe L3 connected to the gas inlet A and exiting the gas outlet of the activated carbon material container AC merges with the second gas pipe L2. The present application adopts activated carbon to pre-adsorb some of the ammonia; At the same time, in order to improve the denitration effect, a part of ammonia is re-injected into the middle part of the adsorption tower.
