摘要
采用二级文氏管净化处理、煤气回收或布袋除尘等技术对济钢120t转炉生产中辅原料及铁合金上料,倒罐间烟气,铁水预处理烟气,转炉一次、二次烟气,炉外精炼等烟尘进行治理,除尘效率达99%以上,转炉一次外排烟尘含量控制在80mg/m3以内,回收一次除尘污泥、除尘灰中氧化铁作为原料使用,年节约成本500余万元。
Adopting some technique measures included secondary Venturi tube treatment, coal gas recovery and hag-type collecting dust to govern smoke dust of raw material and alloy iron feeding, hot metal ladle room, hot metal pretreatment, first and secondary of converter, the dust removal rate is above 99%, the content of smoke dust in once exhausting of converter is controlled in inside of 80 mg/m^3, the iron oxide from dust sludge and precipitating dust can be recovered and used as raw material, cost saving is more than 500 millions RMB one year.
