摘要
针对干熄焦环境除尘烟气中二氧化硫含量严重超标问题,对其含硫来源进行分析,通过将含硫高的循环气体放散气引入焦炉烟气脱硫系统中一并处理后,干熄焦烟气中二氧化硫达到《炼焦化学工业污染物排放标准》特别排放要求。
In view of the excessive level of SO2 content in CDQ dedusting emission,study is made for the sulfur source,i.e.the high sulfur content bleeding circulating gas is transferred to DeSOx system for treatment.The treated SO2 level in the CDQ emission can meet the requirement of'Discharge Standard for Pollutants in Coking Chemical Industry'.
