摘要
能量回收装置的快速发展及其广泛应用是反渗透海水淡化制水成本大幅降低的关键因素之一。设计了具有新型端盘结构的转子式压力交换器,搭建了装置性能测试平台,并对其运行特性进行了测试分析。结果表明:装置在处理量为8.3 m3/h和操作压力为6.0 MPa时,流量和压力的运行稳定性都较好,能量回收效率保持在95.8%～97.7%;在100～500 r/min的转速范围内,装置均具有良好的旋转动平衡性能,并在500 r/min时达到17～18 N.m的最小驱动扭矩值。
The operation cost for seawater reverse osmosis system has been reduced greatly due to the rap- id development and wide application of energy recovery device （ERD）in recent years. In this article, a novel rotary pressure exchanger was designed and manufactured. The corresponding test platform was set up and the operating characteristics of the device were examined and analyzed. The results demonstrated that the device run steadily with a high energy recovery efficiency of 95.8%--97.7% under the capacity of 8.3 m3/h and operating pressure of 6.0 MPa. The device also presents good dynamic balance at rota- tion speed of 100--500 r/min. The minimum torque for driving the device is obtained at the rotation speed of 500 r/rain, which is monitored to be 17--18 N·m.
