摘　　要：烧结是钢铁行业污染物排放最多的工序,随着人们对环境质量的要求越来越高,在对烧结其他污染物加强管控的背景下,铁矿粉烧结排放CO的问题被广泛关注,CO减排势在必行。烧结烟气CO减排高效的治理技术比较匮乏,不能满足钢铁行业烧结机CO减排的要求。本文主要对国内外烧结烟气CO减排技术的研究现状进行总结,分析了烧结过程产生CO的机理,从源头、过程控制以及末端治理三方面协同控制CO减排。Sintering is the process that emits the most pollutants in the iron and steel industry.As people have higher and higher requirements for environmental quality,under the background of strengthening the control of other pollutants in sintering,the issue of CO emissions from sintering of iron ore powder has been widely concerned.CO emission reduction is imperative.The efficient treatment technology for CO emission reduction in sintered flue gas is relatively scarce and cannot meet the CO reduction of sintering machines in the steel industry.This article mainly summarizes the research status and trends of CO emission reduction technology in sintering flue gas at home and abroad,analyzes the mechanism of CO production during sintering process,and discusses CO emission reduction from the three aspects of source,process and end governance.
