Abstract

The invention discloses a dry and wet integrated desulfurization and denitrification device. The device comprises: a boiler or kiln used as an implementation place of dry desulfurization and denitrification; an absorption tower used as an implementation place of wet desulfurization and denitrification; a dry feeding mechanism communicating with the boiler or kiln and used for adding a removal agent used by the dry desulfurization and denitrification into the boiler or kiln; a wet feeding mechanism communicating with the absorption tower and for adding a removal agent used by the wet desulfurization and denitrification into the absorption tower; and a communicating tube connected between the boiler or kiln and the absorption tower. The device has strong desulfurization and denitrification ability, the desulfurization efficiency reaches 99%, and the denitrification efficiency reaches 95%; the device meets the national ultralow emission standards of boiler or kiln desulfurization and denitrification, and realizes the ultralow emission requirement of national environmental protection; and the device has the advantages of investment saving, fast effect, and saving of a large amount of SCR denitrification catalyst.

Description

technical field [0001] The invention relates to the field of gas purification equipment, in particular to a dry-wet integrated desulfurization and denitrification device. Background technique [0002] The flue gas produced in some production processes contains sulfur and nitrate. At present, the flue gas desulfurization mainly uses spraying sulfide absorption liquid to absorb the sulfide in the flue gas. This method has low desulfurization efficiency and high implementation cost; [0003] Flue gas denitrification (DeNOx) mainly uses selective catalytic reduction (SCR) technology. This technology uses ammonia as the reducing agent, and with the help of SCR catalyst, the NOx in the flue gas is reduced to non-toxic N 2 and H 2 O, so as to achieve the purpose of controlling NOx emissions. However, this technology uses a large amount of SCR denitration catalyst, and the removal effect is not good, which cannot meet the national ultra-low emission requirements. Contents of t...
