转炉环集除尘器稳定运行控制与优化
|
摘要
铜转炉工况复杂,难以满足布袋除尘器使用条件,铜行业中少有使用布袋除尘器,本文根据转炉烟气收尘系统的工作原理,针对系统运行效果欠佳的原因,通过对转炉除尘器滤袋堵塞现象的成因分析,并采取有效措施,以满足操作可控,实施优化改进,系统运行效率明显提高,实现布袋收尘器滤袋在线更换,烟尘、重金属等有害物质的排放均优于国家标准限值,金属回收率同步提高,滤袋使用寿命延长,环境得到改善,创造了良好的社会及经济效益。
The working condition of copper converter is complex,It's difficult to meet the flow conditions of the bag dust collector,so rare copper industry use it.The working principle of converter furnace flue gas collection dust system in Jinglong Smelter is introduced,and the cause for poor effect of system operation is analyzed.The phenomenon of Filter bag jam is analyzed,and it's solved.The on-line replacement of Filter bag is realized,the key material such as heavy metals,soot emissions were superior to national standard limit,Improve metal recovery rate synchronization,extend the service life of filter pocket.Eventually the operating efficiency of dust collecting System is improved and the environment becomes better.
