摘要：

韶钢150m³气烧竖窑在出灰时窑顶出现冒尘现象，而且烟尘量大，持续时间长，环保不达标。针对这一问题，通过采取改进引风机参数，改善烟气管道和清理管道积灰，优化多管陶瓷除尘器、脉冲布袋除尘器参数和工艺参数以及窑顶密封等措施，窑顶冒尘得到了较好的治理，达到了环保要求。

Abstract:

Dust emission occurs during the lime discharging process in the kiln roof of 150 m3 gas-burning shaft kiln in Shaoguan Iron & Steel Group Co.,Ltd., the quantity of smoke and dust is large,the duration of time is long,the environmental protection is not up to the standard.In order to solve this problem,some measures were adopted,such as improving the parameters of induced draft fan,improving the dust accumulation in flue gas pipes and cleaning pipes,optimizing the parameters and process parameters of multi-pipe ceramic dust remover,pulse bag dust remover and kiln top seal.The dust emission from the kiln roof has been well controlled and has met the requirements of environmental protection.
