摘　　要：分析了正通选煤厂煤泥处理及产品结构方面存在的问题,对比了降低煤泥产品水分的方法,提出采用STC2000超高压压滤机对煤泥进行脱水提质,并介绍了该设备的结构组成及工作原理,对煤泥超高压压滤脱水回收关键工艺技术系统改造进行了说明。实践证明,STC2000超高压压滤机安装投运以来,运行稳定,煤泥水分降低约8%,提质后的干粉煤泥经破碎后可直接与其他选煤产品进行掺配以优化产品结构,提高煤泥附加值,经济效益与社会效益显著。This paper analyzed the problems of coal slime treatment and product structure in Zhengtong coal preparation plant,compared the methods of reducing the water content of coal slime products,put forward the use of STC2000 ultra-high pressure filter press to dehydrate and improve the quality of coal slime,introduced the structure and working principle of the equipment,and described the transformation of the key technology system of ultra-high pressure filter dewatering recovery of coal slime.Practice has proved that STC2000 ultra-high pressure filter press has been running stably and reducing the coal slime moisture by about 8%since it was installed and put into operation,The improved dry pulverized coal slime can be directly mixed with other coal preparation products after crushing to optimize the product structure and improve the added value of coal slime.The economic and social benefits were significant,and the application prospect was broad.
