摘 要:针对目前污泥含水量高且干化效率低的问题,设计了一种密闭式污泥热干化装置。对含水率为55%~64%的污泥进行了连续一个月的干燥测试。首先对污泥进行采样,分析污泥泥质参数;在此基础上进行主要参数测试,包括湿泥含水率、干泥含水率、进出干湿泥总量、单位能耗脱水量、冷凝水总量和冷凝水成分。结果表明,板框压滤后湿泥平均含水率为63.26%,经低温干化后的污泥含水率平均达到27.06%,且去除1 m3的水仅需耗电298 kW·h。该装置能有效减小污泥体积,降低污泥处置成本。A closed sludge thermal drying device was designed to solve the problems of high sludge moisture content and low drying efficiency.The sludge with moisture content of 55%-64%was dried for a month.Firstly,the sludge was sampled and its parameters were analyzed.On this basis,the main parameters were tested,including moisture content of wet sludge,moisture content of dry sludge,total amount of wet and dry sludge in and out,dehydration per unit energy consumption,total amount of condensate and condensate composition.The average moisture content of wet sludge after plate and frame pressure filtration was 63.26%,while the average moisture content of sludge after low-temperature drying reached 27.06%,and only 298 kW·h of electricity was consumed to remove 1 m~3 of water.The device can effectively reduce the volume of sludge and the operational cost of sludge disposal.
