摘　　要：本文以含水率高于80%的油泥砂为研究对象,探究高效、低成本的油泥砂脱水方式,提出了一套由物理脱水和真空干燥组成的两级联合干燥及余热回收利用的工艺,并建立了一套用于检验该系统的实验装置。实验结果表明,该工艺适用于油田高含水率油泥砂的干燥处理。由该系统处理后的油泥砂含水率可低于30%;吨物料处理能耗在80度电左右。This paper presents a two-stage drying process and heat recovery technology for drying oil-sludge sand, whose moisture content is more than 80%. The drying process is consisted with a physical dehydrator, a vacuum dryer and a heat recovery system. To verify the drying process a unique experimental set was built-up. The preliminary experimental results showed that the process is able to well treat high- moisture content oil-sludge sand de-water. It was observed that the drying system can get a low moisture content less than 30% with the energy consumption at about 80 kwh for a ton oil-sludge sand.
