摘要
为了增强水煤浆生产对原料煤的适应性,并降低能耗,减少污染,针对现有水煤浆生产工艺中存在输送粉尘大、设备效率低、耗能大等问题,经过多年的研究、试验,提出了一种新型的水煤浆生产工艺,采用3台专用设备就能在一条备料生产线上完成混煤、煤泥、配煤等煤种的均匀给料、输送带计量、煤水药配料,块煤破碎和煤泥破碎成浆等作业,结果表明该备料工序具有工艺流程简洁、设备少、占地面积小、煤尘小、环保节能等优点。
To enhance adaptability of production technology of coal water slurry（ CWS） to the feed coal and reduce energy consumption and pollution,the existing problems of production technology in terms of a large amount of delivered dust,low equipment efficiency,high energy consumption and so on were analyzed. Therefore,a new type processing technology of CWS was proposed after years of investigation and experiments. Three specialized equipments were employed to conduct evenly feeding,belt measurement and coal water mixture for different coal types including mixed coal,coal slime,coal blending on a production line of material preparation. In addition,the lump coal breaking and coal slime breaking could be implemented by these equipments. The results showed that the procedure of material preparation had significant advantages such as simple process,less equipments,small land occupation,environmental protection and energy saving.
