摘要：

转子式能量回收装置(RERD)是正位移式能量回收装置的典型代表，是反渗透海水淡化系统中的关键节能设备，对降低产水成本具有重要意义。本文详细论述了RERD的工作原理，并根据其工作原理详细分析了RERD的混合度、转子转速、能量回收效率和使用寿命、流体波动和噪音等四个技术难点的产生原因以及最新的解决方案；论述了关于RERD的国内外研究现状以及RERD的大型化和集成化的发展趋势。本文对RERD的研究进展进行了分析总结，为RERD的基础研究指引了方向，为实现RERD的国产化奠定了理论基础

?The rotary energy recovery device (RERD) which is the typical example on the principle of positive displacement is one of the key facilities in the reduction of the operational cost in a seawater reverse osmosis system. This paper clarified the working principle of the RERD in detail. Four technical difficulties of RERD were concluded based on the working principle of the RERD which are the mixing, the rotor speed, the energy recovery efficiency and the service life, the flow fluctuation and the noise. The creative reason and the research solution about the four technical difficulties were discussed. The research status and development tendency to the enlargement and integration was illustrated. The research progress gives the direction for the fundamental research for the RERD and is the basis of RERD localization.
