Abstract

The invention relates to a pellet flue gas ultra-clean treatment system and an ultra-clean treatment method, and belongs to the technical field of ultra-clean emission. The pellet flue gas ultra-clean treatment system comprises an electric dust remover, a CFB desulfurization absorption tower, an exhaust fan, a bag-type dust remover, an SCR reactor, an induced draft fan and the like. According to the invention, ultra-clean emission of multiple pollutants such as SO2, NOx and dust can be realized, the concentration of SO2 is reduced to 20 mg / Nm<3> or below, the content of NOx is reduced to 30 mg / Nm<3> or below, and the concentration of dust is reduced to 5 mg / Nm<3> or below, so that national standard requirements are met, the occupied area is small, desulfurization byproducts can be fully utilized, no wastewater is generated during denitration, and the like.

Description

technical field [0001] The invention relates to the technical field of ultra-clean emission, in particular to a pellet flue gas ultra-clean treatment system and an ultra-clean treatment method. Background technique [0002] As we all know, pelletizing is a process in which iron concentrate and other raw materials are uniformly mixed with an appropriate amount of bentonite, green pellets are produced by a pelletizer, and then roasted at a high temperature to oxidize and consolidate the pellets. This process is a complex physical and chemical reaction process. Pellet flue gas contains a large amount of SO 2 , NO x , HCl, dioxin and other pollutants and dust, the discharge of pellet flue gas will cause serious pollution to the atmospheric environment. As one of the important sources of pollutant emissions in the iron and steel industry, the sintering and pelletizing process produces sulfur dioxide and nitrogen oxides that account for about 70% and 50% of the total pollutant e...
