叠螺式脱水机在某大型电厂的应用

Application of stacked spiral dewatering filter in a large power plant

介绍了离心式脱水机、板框式脱水机和叠螺式脱水机的工作原理并对其技术、经济指标进行对比,选择成本低、能耗低、脱水效率高的叠螺式脱水机作为某电厂净化站的污泥脱水设备,产出的泥饼含水率低,泥水回用率高,有效减少了电厂的污水排放。

It introduces the working principle of centrifugal dewatering machine,plate-frame dewatering machine and stacked spiral dewatering filter by comparing their technical and economic indexes.It choose the stacked spiral dewatering filter as sludge dewatering equipment for a power plant’s purification station since its low cost,low energy consumption,and high dewatering efficiency.The low moisture content of mud cake and high sludge recycling rate can effectively reduce the sewage discharge of power plant.
