Description

technical field

[0001] The invention relates to the fields of seawater desalination and energy saving and emission reduction, in particular to an electromagnetic energy seawater desalination device and method. Background technique

[0002] The essence of seawater desalination is to separate the salt and water in seawater by doing work. The thermal seawater desalination technology usually boils seawater by heating to generate steam, and the steam flows into the condenser to condense into fresh water. The desalination process consumes a lot of energy. How to reduce the energy consumption in this process is a problem that must be considered in seawater desalination technology.

[0003] In a typical thermal technology, seawater evaporation occurs in the same chamber, and the temperature of the steam is the same as that of the concentrated brine, which causes a large amount of sensible heat to be carried during the discharge of the concentrated brine, resulting in sensible heat l...
