气烧石灰竖窑烟气净化工艺技术改进

Improvement of the air-cleaning technique for gas-burning lime shaft-kiln

介绍了韶钢焙烧厂石灰竖窑烟气除尘工艺系统的技术改进历程,选用工艺先进的脉冲布袋除尘工艺取代水洗喷雾除尘工艺后,彻底解决了烟气外排超标的难题,取得了良好的除尘效果,实现了达标排放,清洁生产.

The details of the technical improvements of the air-cleaning system for the gas-burning lime shaft-kiln in the calcining plant at SISG are described in the article.By replacing the original water mist system with the advanced pulse bag filter,the problem of under-standard gas exhaust was thoroughly solved,and excellent air-cleaning effects were attained,which led to a standard gas exhaust and a clean production.
