Abstract

The invention discloses an electric-driven self-pressurization rotor-type energy recovery apparatus which includes a pressure relieving part shell body, a brine end shell body, a support cylinder body, a seawater end shell body and a low-pressure seawater interface which are successively fixed to each other. A brine distribution rotating disk which is disposed in the brine end shell body and a seawater distribution rotating disk which is disposed in the seawater end shell body are connected to each other through a central shaft. A plurality of water pressure cylinder sets are arranged in the support cylinder body, wherein each water pressure cylinder set is composed of a large-diameter water pressure cylinder and a small-diameter water pressure cylinder which are connected to each other in series. The large-diameter water pressure cylinder is fixedly connected to the brine end shell body and the small-diameter water pressure cylinder is fixedly connected to the seawater end shell body. One piston is disposed in the large-diameter water pressure cylinder and the other piston is disposed in the small-diameter water pressure cylinder. Two pistons, which are disposed in the same water pressure cylinder set, are connected to each other through a piston rod. The brine distribution rotating disk and the seawater distribution rotating disk are driven by a motor. With energy of residual pressure of high-pressure brine, the pressure of raw material seawater can be increased to a level required by a membrane assembly without additionally increasing the pressure by a booster pump.

Description

technical field [0001] The invention belongs to the technical field of reverse osmosis seawater desalination energy recovery, in particular to an electric-driven self-pressurized rotor energy recovery device. Background technique [0002] Compared with other seawater desalination technologies, reverse osmosis seawater desalination has the advantages of low investment, easy maintenance and short construction period. As a freshwater resource increment technology, it occupies more than 60% of the market share. Reverse osmosis seawater desalination is a pressure-driven membrane separation process. According to different salt concentrations, the pressure of raw seawater is raised to 5.5-8.0MPa by a high-pressure pump before entering the reverse osmosis membrane module. About 45% of the raw seawater is desalinated into product water, and the remaining 55% of the high-pressure brine contains about half of the pressure energy output by the high-pressure pump, which is discharged wit...
