亭南选煤厂技术改造

针对亭南选煤厂存在的处理能力低,只是块煤入选,产品结构不合理等问题,从产品结构、选煤方法、工艺流程、设备选型4个方面阐述了选煤厂技术改造方案。本次改造确定的分选方案为:块煤重介浅槽分选机分选+末煤重介旋流器主再选+粗煤泥TBS分选+细煤泥压滤的联合工艺。产品结构根据入厂原煤的煤质和市场需求进行合理优化。通过选用重介浅槽分选机、重介旋流器、干扰床分选机等先进设备提升了选煤厂的分选效率和产品质量。实践证明,选煤厂改造后运行情况良好,提高了处理能力,实现了原煤全部入选,煤泥完全回收,洗水闭路循环,达到了环保要求。产品结构符合市场需求,产品质量优良,节约成本,提高了企业经济效益。

Technical transformation of Pavilion South coal preparation plant

The handing capacity of coal preparation plant is low and only the lump coal can be separated, the products structure is also unreasonable.Introduce the improved design of coal preparation plant from the aspects of products structure, preparation methods, process flow, equipments selection.The transformation method is that, dense medium shallow groove separator separates lump coal, dense medium cyclone recleans slack coal, TBS separates coarse slime, pressure filter disposes fine slime.Optimize the products structure according to the raw coal of coal quality and market demand.The equipments mentioned above improve the separation efficiency and products quality.After transformation, the coal preparation plant improves the handing capacity and economic benefits, realizes closed water circuit. All raw coal can be separated, slime can be fully recycled.The products structure meets the demands of market.
