钢铁厂烧结烟气脱硫技术的研究进展

Research progress of sintering flue gas desulphurization in iron and steel industry

钢铁企业是造成大气污染较为严重的工业企业类型之一,其中烧结工序是主要的污染源。综述了钢铁企业二氧化硫污染现状及主要控制技术,结合钢铁企业烧结烟气的特点,介绍了目前几种烧结烟气脱硫技术,主要介绍了双循环流化床烧结烟气脱硫技术,同时分析了这些烧结烟气脱硫技术的特点和发展趋势。

Sintering plant is the major pollution source of iron and steel industry which belongs to a kind of enterprises leading serious contamination. The situation of pollution and control technology in SO2 discharge at iron and steel industry is described in this article. Combined with the characteristics of sintering flue gas of iron and steel industry, several kinds of sintering flue gas desulphurization technique are introduced, and the double circulation fluidized bed flue gas desulphurization （DCFB - FGD） technology is mostly introduced. At the sametime, analysis the feature and development trend of these technologies.
