| Abstract: | The small reverse osmosis seawater desalination system has low efficiency and high specific energy consumption because of less use of energy recovery device. Therefore, it is the focus of current research to develop the energy recovery device for small reverse osmosis desalination system. The pump-motor energy recovery system has the advantages of simple assembly, low cost, small pulsation, no mixing of salt and seawater and convenient maintenance. It is proved to be suitable for small reverse osmosis seawater desalination system, which is of great significance to improve the system economy. In order to improve pump-motor energy recovery technology and develop efficient and reliable recovery device, the basic working principle and important performance parameters are introduced at first. Secondly the current research status and progress of this kind of device at home and abroad are reviewed, and the limitations and shortcomings of the current research are pointed out. At last, from the three aspects of improving energy conversion efficiency, degree of integration, and operational stability, the future development trends and key scientific issues of pump-motor energy recovery technology are presented. |
