煤矿筛分间是煤矿有组织粉尘排放源一个重要的产尘点,本文以山西美锦集团锦辉煤业有限公司煤矿筛分间为实例,介绍了筛分间粉尘的相关治理措施。在振动筛上方安设集尘罩,然后从集尘罩抽尘至袋式除尘器进行粉尘捕集,集尘率为90%,除尘效率为99%,治理完,粉尘排放浓度满足GB20426-2006《煤炭工业污染物排放标准》要求。
The screening room of coal mine is an important dust producing point of organized dust emission source in coal mine. Taking the screening room of Shanxi Meijin group Jinhui Coal Industry Co., Ltd. as an example, this paper introduces the relevant control measures of dust in the screening room. A dust collecting cover is installed above the vibrating screen, and then the dust is extracted from the dust collecting cover to the bag filter for dust collection. The dust collection rate is 90%, and the dust removal efficiency is 99%. After treatment, the dust emission concentration meets the requirements of GB20426-2006 emission standard of pollutants for coal industry.
