Abstract

Dispositif permettant d'éliminer l'eau d'une solution aqueuse dans une cuve de vide. Selon la présente invention, ledit dispositif comporte une pompe Roots (2) qui est raccordée du côté de l'aspiration à la chambre de gaz (4) située au-dessus de la solution se trouvant dans la cuve de vide (1) et du côté de la pression, via un serpentin de condensation (7) immergé dans la solution, à un orifice de sortie d'eau (8). Ledit dispositif est caractérisé en ce qu'il consomme peu d'énergie pour la condensation de la vapeur d'eau éliminée.
