Seawater desalinator

Abstract

The invention relates to a seawater desalinator, in particular to a seawater desalination device which overcomes the defects of high energy consumption and low efficiency of the prior art and is used for desalinating seawater. The seawater desalination device comprises a hollow shaft, an upper bearing cover, an upper end bearing, a lower end bearing, an upper end cover, a stator part, a rotor part, a lower end cover, a lower bearing cover, a water-containing pan and two sealing sleeve assemblies. When the seawater desalination device is in work, seawater flows in the device from the hollow shaft and enters a cavity chamber with the stator part and the rotor part, external power drives the rotor part to rotate, the seawater is magnified by an electromagnetic reaction between the stator part and the rotor part and heated by generated heat, the rotating speed of the rotor part is increased after magnification is finished, a sealing pressure block is opened by utilizing centrifugal force which is generated by the high-speed rotation, the seawater enters a cavity of an outer cylinder body through a film and a film sealing sleeve, and fresh water flows in the water-containing pan. The invention changes the acting force between the solute and the solvent of an aqueous solution by a magnetic field, improves the flux of the film, increases the seawater temperature and enhances the water permeation capability.

Description

technical field

[0001] The invention relates to a seawater desalination device, in particular to a seawater desalination device which combines magnetization treatment technology and membrane separation technology and integrates temperature, electromagnetic field, centrifugal force and membrane. Background technique

[0002] One of the biggest problems facing the world in the 21st century is the water crisis. Although the total amount of water resources in my country is relatively large, the distribution is uneven, and the per capita resources are small. Some cities are often threatened by water shortages. Therefore, the development of new water resources and the control of water pollution have become a hot topic of concern. Among them, seawater desalination is an important way to obtain water for human life and production. Currently, seawater desalination methods mainly include membrane separation, electrodialysis, and distillation. Among them, the distillation method cons...
