Abstract
Device for desalinating sea water comprising a unit (10) for spraying sea water in the form of droplets, a unit (20) for vaporizing the droplets into steam, a unit (30) for separating steam from salt particles, and a unit (40) for condensing steam into fresh water. The spraying unit comprises a sea water entry (12), an ambient-temperature dry air entry (14), and a device for generating acoustic waves at a frequency greater than 1 MHz focused by means of nozzles (17) receiving the sea water coming from the sea water entry so as to obtain microdroplets having a diameter comprised between about 2.5 microns and about 5 microns.
