In the reverse osmosis sea water desalination process, raw material sea water is required to be pressurized to 5.5-8.0MPa, and 45% of the sea water is separated into desalinated product water through the differentiation of a reverse osmosis membrane, so that more than half of concentrated sea water is discharged in the form of high-pressure strong brine (more than 5 MPa), a large amount of energy is wasted, and the recovery and utilization of the residual pressure of the strong brine are of great significance in reducing the operation energy consumption and the water production cost of a system.
The liquid energy utilization technology can reduce the whole energy consumption of the reverse osmosis sea water desalination system by 40%, can bring great social and economic benefits, and becomes one of key equipment of the technology.
