[0002] The technology close to the present invention is: "low temperature (24 ℃-27 ℃) energy exciter, low temperature (24 ℃-27 ℃) distiller ", (patent application number 85106310) it is to utilize surface seawater (24 ℃-27 ℃) ) and deep seawater (1000 meters deep, 4°C) can be used for seawater desalination and power generation, because the way of condensation is to use deep low-temperature seawater, so its disadvantage is that the cold seawater intake pipeline is very long , the power system for pumping water upward consumes a large part of electricity, and the temperature of cold seawater increases significantly when it enters the condenser along the pipeline, which reduces the available seawater temperature difference, and its equipment manufacturing is very difficult
And its technical solution can only be used for power generation, not for seawater desalination

The present invention belongs to the field of sea water desalting, sewage purifying and new energy source developing and utilizing technology. Ice is stored in winter, and when the environment temperature becomes higher, the temperature difference energy between sea water or sewage and the ice or its cooled air or water is utilized for desalting sea water, purifying sewage and generating electricity. The method includes the following steps: filtering sea water, heating sea water inside a heating system, flash evaporating inside a flash evaporator to evaporize partial sea water into steam, driving the steam turbine with the steam for the generator to produce electricity, condensating the steam in a condensating system to obtain fresh water and collecting fresh water.
