Patent ID: 10315932

Abstract:
A device for desalinating seawater comprises at least three plates (20, 21, 22), at least two evaporation chambers, each of them delimited by two consecutive plates, and entrance means (24) to feed the evaporation chambers with seawater to be desalinated, said entrance means being suitable to feed all the evaporation chambers with seawater from a common source, so that at least one plate is suitable to operate as a condensation surface in one chamber and as an evaporation surface in the next chamber. The device may be arranged in any coastal system that requires a heat flux of low thermal intensity between a hot source (60) and a cold sink (70). The device guarantees said heat flux by means of vapour generation, transportation and condensation, whereby condensed water is collected as a valuable by-product. A method of desalinating seawater comprises the steps of deaerating the seawater to be desalinated and feeding all the evaporation chambers with said deaerated seawater.
