Abstract

The invention provides a differential pressure booster-type energy recovery device based on a reverse osmosis system. The differential pressure booster-type energy recovery device comprises a two-position four-way reversing valve, a first hydraulic cylinder and a second hydraulic cylinder, wherein the first hydraulic cylinder is provided with a piston and a piston rod of the first hydraulic cylinder; and the second hydraulic cylinder is provided with a piston and a piston rod of the second hydraulic cylinder. The device has high energy recovery efficiency; a high pressure booster pump is not required, and the pressure of low-pressure raw material water can be directly boosted to a water inlet pressure of the reverse osmosis system by utilizing the recovered energy, so that stable pressure energy conversion is realized and the equipment investment and equipment selection difficulty are reduced; and simultaneously, the water yield of the reverse osmosis system utilizing the differential pressure booster-type energy recovery device can be changed by adjusting the flow of a high pressure pump or the flow of the energy recovery device.

Description

technical field [0001] The invention relates to energy recovery devices in fluid systems. Background technique [0002] The research on fluid pressure energy comprehensive utilization technology and equipment at home and abroad has made great progress, and many different forms of devices have been developed. Some of these devices have become industrialized products, applied to corresponding industrial fields, and achieved good economic benefits, which is of great help to enterprises in saving energy and reducing costs. [0003] Pressure fluid energy comprehensive utilization equipment is mainly divided into two categories: [0004] One is that the high and low pressure fluid transfers energy by means of the impeller and the main shaft, that is, the mechanical energy is used as the intermediate link of the fluid pressure energy transfer. Typical devices include Francis Pump, Pelton Wheel1 and Turbo Charger. Although the technology of this type of energy recovery device is ...
