摘要
烟气脱硫是从废气中去除含硫物质如SO2,SO3,H2S的一种工艺,怎样脱除烟气中的含硫物质,减少含硫物质排放已逐步成为全球关注的热点。笔者主要介绍了国内外烟气脱硫处理技术研究现状及进展,包括醇胺类离子液体法、石灰石(石灰)/石膏法、双碱法、金属氧化物法、生物膜法、非生物膜法等,对各种方法进行了评价和比较,并对今后烟气脱硫处理技术的发展提出了建议。
The flue gas desulfurization is to remove sulfur substances from exhaust gas, such as SO2, SO3, H2S. It has gradually become the focus of global attention to remove sulfur containing materials in flue gas and reduce sulfur material discharge. In this paper, flue gas desulfurization treatment technologies at home and abroad were introduced, such as alcohol amine ion liquid method, lime method, dual alkali method, metal oxide method, biofilm process, non biofilm process, and so on. At last, above methods were compared and the future research suggestions were presented.
