Description
technical field [0001] The invention belongs to the technical field of salt solution concentration, and in particular relates to a local heating type salt solution water separation device based on homo-ion rejection. Background technique [0002] With the increasingly serious energy and environmental problems, energy conservation and emission reduction have received great attention. Energy innovation plays a key role in realizing energy conservation and emission reduction. The improvement of energy utilization efficiency and the development of renewable energy are conducive to alleviating the current pressure on energy and the environment. The fields of seawater desalination, dehumidification solution regeneration and industrial wastewater treatment all involve the separation of salt solution and water. For example, in the field of seawater desalination, water needs to be separated from seawater, and after the water is separated, the seawater becomes a concentrated solution;...
