Abstract

The invention discloses a thermodynamical seawater desalination system without permeable membranes. The system comprises a wave-energy pressure pump, wherein the wave-energy pressure pump is connected with a seawater evaporation heat exchanger through a pipeline, an outlet of the seawater evaporation heat exchanger is connected with a throttling valve through a pipeline, an outlet of the throttling valve is connected with a refrigeration evaporator, and an outlet of the refrigeration evaporator is connected with the wave-energy pressure pump, thereby forming a loop; and a refrigeration working medium is arranged in the loop pipeline. The seawater evaporation heat exchanger contains a seawater evaporation cavity which is connected with a seawater inlet pipeline, a concentrated seawater outlet pipeline and a steam outlet pipeline. The steam outlet pipeline is connected with a condenser, and an outlet of the condenser is connected with a fresh water outlet pipeline. The refrigeration working medium adopts an industrial refrigerant. The system has the advantages of simple structure and low cost, is convenient to operate, and can implement large-scale seawater desalination.

Description

technical field [0001] The invention relates to a seawater desalination system, in particular to a wave energy seawater desalination system, which belongs to the energy field. Background technique [0002] The water reserves on the earth are extremely rich, but 96.52% of them are sea water, and 2 / 3 of the remaining fresh water is concentrated in the southern half, so there are very few fresh water resources that can be directly used by people. The problem of fresh water resources has become an important factor restricting the economic and social development of all countries in the world. Seawater desalination is an important way to solve the freshwater problem. [0003] There are many methods of seawater desalination. The seawater desalination methods put into industrial production around the world mainly include distillation, electrodialysis, reverse osmosis, etc., but the common problems of these methods are high energy consumption, high cost, and the need to consume a lo...
