烧结烟气超低排放技术应用研究

Analysis on Application of Ultra-low Emission Technology in Sintering Flue Gas

本文介绍了钢铁企业烧结烟气中烟粉尘、二氧化硫和氮氧化物等污染物的产生及排放情况,对比分析了目前针对烧结烟气中颗粒物、二氧化硫、氮氧化物、二噁英等典型污染物主要采用的末端控制技术情况,对应用于烧结烟气超低排放控制的高效除尘技术、脱硫技术、脱硝技术的优缺点及其发展方向进行探讨。

This paper introduced the production and emission of typical pollutants such as smoke and dust,sulfur dioxide and nitrogen oxide in sintering flue gas in iron & steel enterprises, analyzed the application of terminal control technology for different pollutants such as particulate matter, sulfur dioxide,nitrogen oxide and dioxin in sintering flue gas, discussed the advantage and disadvantage of effective dust removal technology, desulfurization technology and denitrification technology and their development direction of ultra-low emission control in sintering flue gas.
