摘要
焦炉烟气经脱硝系统脱除NO_x,余热锅炉系统对烟气进行降温并产生低压蒸汽,脱硫系统脱除烟气中SO_2,除尘系统脱除烟气中颗粒物,最终排放烟气符合GB 16171—2012《炼焦化学工业污染物排放标准》相关规定。
bThe coke oven flue gas goes to the de-NOx system to remove NOx ,passes the waste heat boiler system to reduce temperature and generate low pressure steam,and then travels through the deSOx system and de-dusting system to remove SOx and dust respectively. Finally the discharged waste gas meets the relevant requirements stipulated in Emission Standard for Pollutants in Coking Chemical Industry GB 16171—2012.
