摘　　要：某公司乙烯裂解炉烧焦罐系统原烟气干式旋风分离技术在使用中存在排放烟气颗粒物含量高以及二次环境污染等问题。为满足环保控制标准,经过试验摸索,提出了在原烟气干式旋风分离技术的基础上改造为烟气饱和湿式旋风分离技术的方案,并将原地面清焦池改为地下井池,采取分级过滤除焦、污水分控、焦粉回收利用等技术。实践证明烧焦罐系统改造效果良好,大气排放指标符合环保要求,清焦池焦污分离彻底,焦粉实现回收利用,节能减排效果明显。The original dry flue-gas cyclone separation technology used in the coke-burning drum system of the ethylene cracking furnace had some problems,such as high amount of particles in discharged flue gas and secondary environmental pollution.In order to meet the environmental protection control standards,a scheme of renovating the original flue gas dry cyclone separation technology into the wet flue-gas saturated cyclone separation technology was put forward through research and experiment,and the original ground coke clearing pond was changed into an underground well pond,and the technology of grading filtration and decoking,sewage control and coke powder recovery was adopted.The results showed that the renovation of the coke-burning system had a good effect,the emission index met the requirements of environmental protection,the coke pollution in the coke cleaning tank was completely separated,the coke powder was recovered,and the effect of energy saving and emission reduction was obvious.
