Problems solved by technology
[0002] It is estimated that there are about 1.4×1018 tons of water on the surface of the earth, of which 97.5% is sea water containing salt, only a small amount of 2.5% is fresh water, and 98% of the fresh water is ice that exists in the North and South Poles and Iceland, and due to the increase in population Domestic wastewater, a large amount of sewage produced after industrialization, and a large number of improperly felled primitive rainforests have completely destroyed the ecological environment of the earth. The greenhouse effect is becoming more and more serious, and water resources are dwindling. How to turn seawater into freshwater is an urgent issue for human beings. The conversion of seawater into freshwater is nothing more than obtaining freshwater through solar evaporation or steam heating and distillation of seawater. Although the former can save energy, the output is not large and the economic benefits are not high. Although the latter can be produced in large quantities, However, it consumes a lot of energy, and it is difficult to deal with the boiler afterwards, and the cost is high, so the method of turning seawater into fresh water has not been really implemented so far.

Embodiment Construction
[0020] The specific implementation of the step of changing sea water to fresh water in the method of the present invention will be described in detail below in conjunction with the drawings.
[0021] Such as figure 1 Shown, is the first embodiment of the present invention sea water desalination.
[0022] Step 110: introducing seawater and purifying it, that is, introducing seawater into the preset storage tank, allowing the seawater to settle and purify naturally;
[0023] Step two 20: freezing the seawater, that is, freezing the purified seawater into granular ice;
[0024] Step 3 30: apply centrifugal force to the granular seawater ice cubes to precipitate bittern, that is, apply centrifugal force to the granular seawater ice cubes, so that the salt bittern in the seawater ice cubes is separated from the seawater ice cubes, because the salt molecules and water molecules are in a loose physical relationship. The form is combined into seawater ice and the specific gravity of...

A process for desalinating seawater includes such steps as depositing for cleaning seawater, icing, applying external force to educe out the bittern from ice, and melt-out the ice to obtain the drinking fresh water.
