黄玉川矿井洗煤厂工艺设计浅析

摘要

介绍了黄玉川煤矿4＃与6＃上煤层的煤质特征，分析了原煤的可选性，结合市场需求情况，确定了以火力发电用煤为主的产品结构；从技术、经济角度综合考虑，制定了块煤浅槽＋末煤无压三产品重介旋流器＋煤泥压滤回收的洗选工艺，这种工艺具有洗选系统先进、生产方式灵活性强、设备可靠、产品结构丰富的特点。黄玉川矿井洗煤厂自投产以来，生产状况良好，商品煤产率高，各项经济技术指标达到设计要求。%Introduces the coal quality properties of 4#and 6 #upper coal seam in Huangyuchuan coal mine and analyzes raw coal washability.Defines the product structure which is sold to the coal -burning generating plant in or-der to adapt to the market.The preparation process is set out from technique and economy,the final preparation process includes lump coal shallow slot,dense medium cyclone for fine coal non -pressure three -product and cham-ber pressure filter for coal slime.The process has the characteristics of advanced systems,flexible production meth-ods,reliable equipment and a variety of product structures.Since the Huangyuchuan coal preparation plant has been put into operation,production has been smoothed,and the yield of commercial coal is high,all economic and techno-logic indexes for production and construction are in accord with design requirements.
