综合除尘系统在正通选煤厂的应用实践

Application practice of comprehensive dust removal system in Zhengtong Coal Preparation Plant

介绍了正通选煤厂基本工艺情况,分析了生产工艺中的粉尘来源以及产尘机理,采取了惯性沉降、喷雾除尘、机械除尘等手段进行综合除尘治理。除尘设备投用后有效降低了粉尘浓度,并且除尘系统建设投资小,运营成本低。

The basic process of Zhengtong coal preparation plant was introduced,the dust source and dust generation mechanism in the production process were analyzed,and the comprehensive dust removal was carried out by means of inertial sedimentation,spray dust removal and mechanical dust removal.After the dust removal equipment is put into use,the dust concentration is effectively reduced,and the dust removal system construction investment is small,and the operating cost is low.
