摘　　要：在钢铁厂污染物排放总量中,烧结机排放烟气中的颗粒物约占40%、二氧化硫约占70%、氮氧化物约占50%,根据现有钢铁企业烧结机烟气脱硝的工艺和国家超低排放政策的要求,探讨分析了氧化法脱硝、活性炭法脱硝以及中低温SCR脱硝和中高温SCR脱硝工艺的优缺点。表明在目前钢铁企业超低排放的趋势要求下,中高温SCR脱硝是比较适合烧结机烟气脱硝的技术路线。Sintering flue gas particles,SO 2 and NO X emissions in steel plant emissions accounted for 40%,70%,50%or more of the total,according to the existing process of sintering flue gas denitration in iron and steel enterprises and national policy of ultra-low emissions requirements,analyzes the oxidation process denitration,activated carbon process denitration and of low temperature SCR denitration and high temperature in the advantages and disadvantages of SCR denitration technology.It shows that under the current trend of ultra-low emission in iron and steel enterprises,medium-high temperature SCR denitrification is a more suitable technical route for denitrification of sintering machine flue gas.
