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 rapid development of energy recovery devices and their wide application is one of the key factors in drastically reducing the cost of reverse osmosis desalination water. The rotor type pressure exchanger with a new type of end plate structure was designed and a device performance test platform was set up. The operation characteristics of the device were tested and analyzed. The results show that the operating stability of the flow rate and pressure are good with the treatment capacity of 8.3 m3 / h and the operating pressure of 6.0 MPa, and the energy recovery efficiency is maintained at 95.8% -97.7%; at 100 ~ 500 r / min In the speed range, the devices have a good rotational balance and achieve a minimum drive torque of 17-18 Nm at 500 r / min.
