摘　　要：本文对转炉一次烟气湿式净化与回收系统升级改造进行了阐述,针对不同厂房条件提出相应的改造方案,新增防爆型圆筒湿式电除尘器进行精除尘,文中详细描述了其性能及技术特点。改造后烟尘排放指标≤15 mg/Nm^3,煤气含尘浓度≤10 mg/Nm^3,可实现转炉煤气综合回收利用。本文对钢铁企业全面实现转炉一次烟气净化回收达标提供了可行性解决方案。This paper aim at upgrading and improvement of converter primary flue gas wet purification recovery system,it brings corresponding transformation to the different plant conditions. A new explosion-proof wet cylinder electric precipitator is added to refined dedust process,its performance and characters are described in detail. It shows that dust emission is less than 15 mg/Nm3,and dust concentration is less than 10 mg/Nm3,which makes converter gas purification recovery come true. This paper provides feasible solution to realize converter primary flue gas purification and recovery of iron and steel enterprises.
