Abstract

The invention provides an electromechanical integration type turbine type energy recycling device assembly which comprises a motor, a spindle, a high pressure pump, a reverse osmosis system and a turbine. The motor is connected with the high pressure pump through the spindle, the turbine is connected with the high pressure pump through the spindle, and a water outlet of the high pressure pump is connected with a water inlet of the reverse osmosis system. The reverse osmosis system is further provided with a fresh water outlet and a concentrated seawater outlet. A water outlet pipe is installed at the concentrated seawater outlet of the reverse osmosis system, the turbine is installed on the water outlet pipe, the motor drives the spindle to rotate, the spindle drives the high pressure pump to inject high pressure seawater into the reverse osmosis system, the seawater passes through the reverse osmosis system to be separated into concentrated seawater and fresh water, the fresh water is discharged from the fresh water outlet, and the concentrated seawater is discharged from the concentrated seawater outlet through the water outlet pipe by the turbine. When the concentrated seawater passes through the turbine, the seawater can drive the turbine to rotate, and the turbine drives the high pressure pump to run through the spindle simultaneously. By means of the assembly, system energy saving efficiency and energy recycling efficiency are greatly improved, cost is greatly reduced, and the assembly is simple in structure and suitable to be made into large size.

Description

technical field [0001] The invention relates to an energy recovery device assembly for seawater desalination and discharge of concentrated brine, in particular to an electromechanical integrated turbine energy recovery device assembly. Background technique [0002] At present, more than 150 countries and regions in the world are using seawater desalination technology. 63.1% of seawater desalination is used for municipal water supply, solving the domestic water problem of more than 200 million people; industry and electric power follow, accounting for 31.4%. Among them, the domestic and industrial water in the Gulf countries mainly comes from seawater desalination, and 70% of Israel and 98% of the drinking water in the United Arab Emirates come from seawater desalination. Therefore, desalination of seawater has become an important source of fresh water for the future economic and social development of mankind. [0003] There are many methods for seawater desalination, and th...
