Abstract

The invention discloses a seawater desalting system. The seawater desalting system comprises multiple seawater desalting tanks, used for separating seawater into pure water and saline water; a refrigerating unit, used for freezing the pure water in the seawater flowed through the seawater desalting tanks; an ice melting unit, used for melting the frozen pure water; and a pressure-reducing explosion-proof device, used for matching with the refrigerating unit, and preventing excessive pressure intensity of the refrigerating unit. The seawater desalting system is capable of using different freezing points of the pure water and the saline water, freezing the pure water by using the refrigerating unit, and rapidly separating the saline water and the pure water. In addition, in such a structure,the saline water and the pure water are completely separated, a situation of incomplete saline water separation is not existent, and the desalting effect is good; and secondly, in the structure, a lot of the seawater can be desalted every time, and working efficiency of the system is improved in the greatest degree.

Description

technical field [0001] The invention belongs to the technical field of seawater desalination, in particular to a seawater desalination system. Background technique [0002] The most difficult link in the seawater desalination process is to desalinate the seawater. The traditional desalination method is usually to pass the purified seawater through the ultrafiltration membrane. Only pure water with small molecules can pass through the ultrafiltration membrane, so that the final preparation is pure water. However, in this way, hundreds of square meters of ultrafiltration membranes need to be installed, which not only costs a lot of equipment investment, but also has a slow filtration effect. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a seawater desalination system with low equipment cost and high filtration efficiency. [0004] In order to achieve the above object, the present invention adopts t...
