Abstract

L'invention concerne un procédé et un appareil, à grand rendement énergétique, pour le dessalement de l'eau. A partir d'un piege thermique, une thermopompe transfère de la chaleur fournissant la chaleur de vaporisation à de l'eau salée introduite dans une zone d'évaporation. Cette zone est maintenue à une pression inférieure à la pression atmosphérique, de sorte que l'eau salée bout à 5,5 degrés C au moins au-dessous du point ambiant de rosée. La dépression est maintenue dans la zone d'évaporation par une pompe à vide et par condensation de la vapeur dans une zone de condensation d'où l'on collecte l'eau douce. La chaleur de condensation est dissipée dans un piège << froid >> ou grâce à un appareil de refroidissement par evaporation. L'appareil peut fonctionner dans des régions très chaudes ou sur des navires en mer.An energy efficient method and apparatus for the desalination of water is disclosed. From a heat trap, a heat pump transfers heat providing the heat of vaporization to salt water introduced into an evaporation zone. This zone is maintained at a pressure below atmospheric pressure, so that the salt water boils at least 5.5 degrees C below the ambient dew point. The vacuum is maintained in the evaporation zone by a vacuum pump and by condensing the steam in a condensation zone from which fresh water is collected. The heat of condensation is dissipated in a "cold" trap or through an evaporative cooling device. The device can operate in very hot regions or on ships at sea.
