| 摘 要： | 能量回收装置是反渗透海水淡化系统的核心元件之一,通过回收高压盐水的压力能来降低能耗和节约成本,加强其基础研究并突破技术瓶颈是缓解我国水资源危机的战略选择。根据工作原理将反渗透海水淡化能量回收装置分成液力透平式、正位移式和泵-马达式3类,主要从结构、原理、效率和应用等方面对国内外研究进展进行综述和分析,并对我国能量回收装置的发展方向和关键技术进行总结展望。研究表明,液力透平式装置已逐渐被市场淘汰,占据市场主流地位的正位移式装置也存在技术缺陷,而泵-马达式装置的集成化设计和降低工作能耗是未来的重要研究方向。

| Abstract: | Energy recovery device (ERD) is one of the core components of seawater reverse osmosis desalination system which can reduce energy consumption and save cost by recovering the pressure energy of high pressure brine, strengthening basic research on it and breaking technical bottleneck are strategic choices to alleviate the water resources crisis in China. According to the working principles, ERD can be divided into three types: hydraulic turbine type, positive displacement type and pump-motor type. Research situation of ERD at home and abroad is reviewed, and the development direction and key technologies of ERD in China are summarized and prospected. It shows that the hydraulic turbine type device has been gradually eliminated, and the positive displacement type device which dominate the market has technical drawbacks. At last, integrated designing and reducing energy consumption of the pump-motor type device are significance research direction in the future. |
