摘要
烧结烟气污染物排放限值日益严格,继火电行业的"超低排放",烧结行业烟气污染物"超低排放"有望实施。本文对现有烟气净化技术进行了论述,并前瞻性的针对有望实现"超低排放"的烟气净化技术,如源头氮氧化物(NO_x)控制技术、选择性催化还原(SCR)脱硝技术、活性炭多污染物协同高效净化技术等进行了其各自优缺点的分析,并对各技术的适用性提出了一些建议。
The sintering flue gas emission limit is becoming more and more strict, similar to the ultra-low emission standard of thermal power industry, it is speculated that the ultra-low emission standard of flue gas pollutants is imperative. The existing flue gas purification technologies were described in this paper, and the prospective "ultra-low emission" technologies of flue gas purification, such as the source NOx control technology, the selective catalytic reduction technology and the AC collaborative multi-pollutant purification process etc. were analyzed in terms of their advantages and disadvantages, and some suggestions were also put forward for applicability of each technology.
