Description
Technical Field
The present invention relates to an energy recovery device.
Background
The energy recovery device can be mainly classified into a turbine type and a positive displacement type according to the working principle. The turbine type energy recovery device mainly has a hydraulic turbine type, generally needs to be subjected to two conversion processes of pressure energy, mechanical energy and pressure energy, and the energy recovery efficiency is generally 50-70%. The positive displacement type energy recovery device utilizes a mode of directly pressurizing the high-pressure concentrated water discharged by the reverse osmosis system to feed the seawater to recover energy, and the energy recovery efficiency is generally 92-95%.
The surfaces of a valve plate and a flow distribution plate of the conventional positive displacement energy recovery device are provided with polyether ether copper, the valve plate and the flow distribution plate are washed by water flow for a long time in operation, when the device operates at high frequency, the flow distribution plate and the valve plate are not resistant to abrasion of particles, the particles have larger abrasion to polyether ether ketone, the performance of a pressure exchanger is greatly influenced, the service life of the device is shortened, the manual maintenance cost is increased, and the problems of insufficient strength and difficult processing and forming of a complex structure caused by the complete use of ceramic materials are solved.
In view of the above, there is a need for an improved energy recovery device to solve the above problems.
