为减排烧结烟气污染物,活性焦(炭)干法烧结烟气净化技术在钢铁行业的应用得到了关注。本文介绍了活性焦(炭)干法烟气净化技术的工程装备、在国内外烧结脱硫脱硝脱二噁英项目中的应用,并给出了建议。应用和分析表明,活性焦(炭)脱硫技术需进行成本降低和技术完善,值得在我国钢铁行业烧结烟气脱硫脱硝脱二噁英(PCDD/F)领域逐步推广。
In order to reduce emissions of sintered flue gas pollutants, active coke (charcoal) dry sintering flue gas purification technology in the steel industry has been the concern. This paper introduces the engineering equipment of the active coke (flue gas) dry flue gas purification technology and its application in sintering desulfurization and denitrification dioxin project at home and abroad, and gives some suggestions. The application and analysis show that the activity coke (charcoal) desulfurization technology needs cost reduction and technology improvement, and it is worth to be gradually promoted in the field of sinter flue gas desulfurization and denitrification dioxin (PCDD / F) in China’s iron and steel industry.
