Abstract

L'invention porte sur un système à plusieurs étages pour le dessalement de faible enthalpie qui est constitué d'évaporateurs (lv) reliés en série constitués de condenseurs (cv) disposés sur un seul niveau au sommet d'une tour (40), leurs chambres d'évaporation respectives (ev) étant disposées à des niveaux de plus en plus bas et reliées aux condenseurs (cv) par des conduits d'air verticaux (2v) de hauteur de plus en plus grande. Le système est basé sur l'ébullition violente/éclair d'eau de mer qui a été chauffée à une température légèrement inférieure au point d'ébullition et introduite dans un environnement de plus basse pression. Du vide passif est employé, lequel est produit par application de la pression atmosphérique et de la gravité. L'augmentation de la pression par paliers (pv) est réalisée par augmentation progressive du volume des évaporateurs. L'évacuation de l'air est réalisée par le vide dynamique produit dans des éjecteurs (12, 13a, 13b) qui emploient l'eau dessalée produite et la saumure rejetée comme milieu auxiliaire.
