Abstract

La présente invention concerne une installation de dessalement d'eau de mer dans laquelle une dépression est produite dans un condensateur (20) et un évaporateur (7), sous l'effet de la force de la pesanteur d'une colonne d'eau dans une conduite destinée à de l'eau dessalée (22). Cela permet de limiter la tension de vapeur au-dessus d'un niveau d'eau salée (30) et d'un niveau d'eau (32), et ainsi de diminuer la température d'ébullition de l'eau à dessaler dans l'évaporateur (7). On obtient ainsi par l'apport de quantités d'énergie thermique relativement limitées, un dessalement efficace à rendement élevé de l'eau salée. Seule une quantité d'énergie limitée est nécessaire en complément de l'énergie thermique, pour entraîner une pompe (36).
