Abstract

The invention discloses a double-rotary disc coupling typed pressure exchanger of seawater or bitter saline water reverse osmosis desalination system, which comprises the following parts: cylinder, left rotary disc, right rotary disc, left end lid, right end lid and middle axle. The invention increases single set disposing load of pressure exchanger, which reduces rotary speed to flow working liquid continuity and stability.

Description

technical field [0001] The invention belongs to the field of recovery and utilization of fluid pressure energy, and in particular relates to a double-rotary disc coupled pressure exchanger for a seawater or brackish water reverse osmosis desalination system. Background technique [0002] In recent years, with the rapid development of energy recovery technology and the continuous improvement of device efficiency, the water production energy consumption of reverse osmosis seawater desalination system has been greatly reduced, thus creating good conditions for the widespread promotion and application of this technology. The energy recovery device has become one of the necessary equipment for the seawater or brackish water reverse osmosis desalination system. At present, the existing energy recovery devices in the international market are mainly divided into two types according to the working principle, namely the hydraulic turbine type (also known as the centrifugal type) and t...
