焦炉烟气非甲烷总烃治理工艺探讨

NMHC treatment process concept of coke oven flue gas

焦炉炉墙串漏导致焦炉烟气中非甲烷总烃(NMHC)含量升高,对人体健康和大气环境造成严重危害。阐述了焦炉烟气NMHC排放特征,基于对VOCs治理工艺和烟气超低排放处理工艺分析,提出了增设NMHC反应器、在脱硝反应器内进行扩容和采用复合滤筒技术等焦炉烟气NMHC末端治理设想,并给出了NMHC催化剂的选用建议。

The leakage of coke oven wall leads to the increase of NMHC content in flue gas,causing serious harm to human health and atmospheric environment.The emission characteristics of NMHC in flue gas was described.Based on the analysis of treatment process of VOCs and process of flue gas ultra-low emission,the NMHC terminal treatment concept was proposed,i.e.adding NMHC reactor,capacity expansion of SCR reactor and using composite filter cartridge,and the suggestion on the selection of NMHC catalyst was given.
