Abstract

L'invention concerne un procédé et un dispositif fonctionnant notamment selon ledit procédé, en vue de récupérer un liquide retraité (9) à partir d'un liquide contaminé (6), par évaporation et condensation avec de l'air chauffé servant de matériau porteur. Selon l'invention, l'air passe par convection naturelle dans un circuit (1) sensiblement fermé, l'air étant chauffé dans un collecteur d'air (2) (collecteur solaire), pour traverser ensuite un évaporateur en cascade (4) qui est parcouru par le liquide contaminé (6). Une fois l'air chaud saturé (7) sorti de l'évaporateur en cascade (4), l'humidité absorbée rejoint un condensateur suivant (8). L'air refroidi et séché retourne ensuite dans le collecteur d'air (2).
