摘要
寒冷地区某选厂磨浮车间大型振动筛生产过程中产生大量粉尘,为降低岗位粉尘浓度,改善工作环境拟设计施工除尘系统。综合考虑冬季保暖减少换气、半自磨加水降温产生蒸汽、车间生产系统布置、粉尘特性等条件,设计采用高效湿式除尘系统和振动筛整体密闭罩。通过实施前后粉尘检测结果对比分析,说明湿式除尘系统运行效果良好,改善了作业环境,达到了国家环保标准要求。
In order to reduce the dust concentration and improve the working environment,a dust collection system is designed and constructed in the production process of large vibrating screen in a flotation workshop of a cold region concentrator. Considering the conditions of keeping warm in winter,reducing ventilation,semi-autogenous grinding and water cooling to produce steam,layout of workshop production system and dust characteristics,a high efficiency wet dust collection system and integral enclosure of vibrating screen were designed. Through the comparative analysis of dust test results before and after implementation,it shows that the wet dust collection system works well,improves the working environment and meets the requirements of national environmental protection standards.
