有色金属冶炼尾气脱硫脱硝处理技术研究进展

Desulphurization and denitrification of tail gas in non-ferrous metal smelting

有色金属冶炼是二氧化硫和氮氧化物的主要来源之一,对大气环境影响极大。对目前的烟气脱硫脱硝一体化技术研究进展进行了综合论述,对等离子体法、循环流化床法、络合吸收法等7种脱硫脱硝一体化技术进行综合论述,对不同的脱硫脱硝技术的原理和优缺点进行简单的概括,旨在使读者对已有的脱硫脱硝技术进行了解。

Non-ferrous metal smelting was one of the main sources of SO2 and NOx,which had a great impact on the atmospheric environment.In this paper,the research progress of flue gas desulfurization and denitrification was summarized.We mainly introduced seven kinds of flue gas desulfurization and denitrification,such as the plasma technology,flue gas circulating fluidized bed(CFB)and solid adsorption/regeneration processes,etc.Then we analyzed the principles and advantages and disadvantages of different simultaneous desulfurization and denitrification technologies in order to make readers understand the existing desulfurization and denitrification technologies.
