根据太原选煤厂生产工艺的特点和现场的实际情况，对该厂的粗煤泥（精煤）、浮精和尾矿煤泥3个环节的脱水工艺进行了改造。粗煤泥脱水采用先进的煤泥旋流器，同时改变了脱水筛的入料方式；浮精脱水运用快开式隔膜压滤机，进行了整个工艺系统的改造；尾矿煤泥在脱水筛前，用煤泥旋流器进行了预先分级浓缩，提高了脱水筛的入料浓度。通过煤泥脱水环节的改造，使精煤和尾矿煤泥的水分降低，提高了产品质量，赢得了市场，取得了较好的经济效益。

According to the characteristics of production technology of Taiyuan coal preparation plant and the ac-tual situation,reformed the dehydration process of three links of the coarse slime(clean coal),flotation concentrate and tailings slime.Coarse coal slime dewatering adopts advanced coal hydrocyclone and changes the dewatering screen feeding method.Flotation concentrate dewatering reformed the whole process system by swift diaphragm filter press. The tailings slime was grading concentrated by coal slime hydrocyclone before it entered into dewatering screen,im-proved the material concentration of dewatering screen.Through the transformation of coal slime dewatering process, the water content of the final concentrate and tailings slime are greatly reduced,improved the quality of the products, won the market,obtained good economic benefits.
