Abstract In order to meet the needs of energy saving and consumption reduction in small- and medium-sized seawater desalination system, a new swash plate plunger type energy recovery device was designed and developed. Based on AMESim simulation software, the hydraulic simulation model of swash plate plunger type energy recovery device and the fluid calculation model of reverse osmosis desalination system are constructed, and the coupling operation performance of swash plate plunger type energy recovery device in desalination system is simulated. The research results show that under the condition of 6.0 MPa high pressure inlet pressure, 18 m³·h^-1 design capacity and 735 r·min^-1 swash plate speed, the maximum flow and pressure fluctuation rates of the increased and relieved fluids are 1.48% and 2.71%. The increased and relieved fluids show good flow stability during the operation of the unit. At range of 10—25 m³·h^-1, with the increase of capacity, the maximum fluctuation rate of flow and pressure relief fluid increases to 1.54%, the maximum fluctuation rate of pressure increases to 2.83%, and the maximum fluctuation rate of flow and pressure only increases by about 0.1% compared with the designed capacity, which indicates that the device has good capacity flexibility and the comprehensive energy recovery efficiency is always above 97% throughout the variable capacity range. The swash plate plunger type energy recovery device provides a new choice for the efficient and reliable operation of small and medium-sized desalination systems due to its good flow operating flexibility and high energy recovery efficiency.
