Abstract

An electromagnetic energy seawater desalination device relates to the field of seawater desalination, energy conservation and emission reduction. The electromagnetic energy seawater desalination device comprises a capillary medium and a condensing device. The capillary medium is communicated with seawater, and a nano magnetic-based material is arranged on the surface layer of the capillary medium.The nano magnetic-based material is placed in an alternating magnetic field and cuts the alternating magnetic field to generate heat, the heat acts on seawater among pores of the nano magnetic-basedmaterial to generate steam, and the steam is condensed into fresh water through the condensing device.

Rapid heating of thin-layer seawater is achieved through the electromagnetic heat generation technology, sensible heat loss is avoided, and the energy conversion rate in the seawater desalination process is increased.

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...

Problems solved by technology

[0006] However, although scientists have tried various methods, it is still difficult to make further breakthroughs

The most critical reasons are as follows: (1) There is a heat dissipation loss of nearly 8% in the heat transfer process. The root cause of this loss is that the heating process has not achieved true thermal focus, and there is a heat transfer loss. (2) The radiation heat is actually used for heating The ratio of seawater is small, and the material has high heat reflectivity
