What is seawater desalination?

Desalination refers to the removal of extra salt and minerals from seawater, and then fresh water treatment. In this process, the plate heat exchanger heats up through high temperature, and the evaporation of seawater will separate the salt from the larger volume of impurities, which will become fresh water through other processes in the future.

Related study about seawater desalination plate heat exchanger

Due to the scarcity of fresh water resources, seawater desalination is the main method for people to obtain fresh water, and heat exchange equipment plays a very important role in it. Therefore, plate heat exchangers have great application prospects in the desalination industry. The plate heat exchanger can carry out the heat exchange of steam-water and water-water, which is convenient and quick.

Due to the high content of chloride ions in seawater and strong corrosiveness, when stainless steel plates are used, seawater as a heat exchange medium will cause serious corrosion to the heat exchanger, which will significantly reduce the service life of the heat exchanger. Therefore, the application of titanium plate-plate heat exchangers made of titanium and titanium alloys in seawater desalination is very anticipated. Titanium has the characteristics of good corrosion resistance, high heat transfer efficiency, smooth surface without scaling layer, small specific gravity, high strength, small equipment volume and quality, etc. It is widely used in chemical industry, petroleum, shipbuilding, seawater desalination, petrochemical industry, etc. Heat exchange system. Titanium has strong corrosion resistance to chlorine.
