as shown in fig. 1, the present embodiment provides an energy recovery device for high-pressure reverse osmosis, including: the device comprises a supercharging mechanism 1, a first-stage membrane component 2, an energy recovery mechanism 3 and a second-stage membrane component 4; the first-stage membrane module 2 is pressurized by the pressurizing mechanism 1, and then the desalinated first-stage concentrated water enters the energy recovery mechanism 3; the energy recovery mechanism 3 is suitable for collecting the pressure of the first-stage concentrated water to desalt the first-stage concentrated water by the second-stage membrane module 4. The concentrated water enters the energy recovery mechanism 3 through the first section of concentrated water to recover the pressure energy therein, and compared with the method of directly discharging the concentrated water through the first section of concentrated water, the desalination rate is effectively improved, and the operation cost is also reduced.
In this embodiment, the pressurizing mechanism 1 includes: a booster pump and a high pressure pump arranged on the pipeline. The pressure is applied to the first-stage membrane module 2 through a booster pump and a high-pressure pump so that the first-stage membrane module 2 can normally desalt the seawater.

The plunger cylinder 301 absorbs and pressurizes water by a volume change generated when the piston 302 reciprocates in the cylinder bore. Because the piston 302 and the inner cavity of the cylinder body are cylindrical surfaces, high-precision matching is easy to obtain, the sealing performance is good, and higher volumetric efficiency and total efficiency can be still kept when the piston works under high pressure.
