The invention concerns an evaporation device (10) of a liquid solution (SO) based on solvent and compounds or solutes inside an envelope (11, 111, 211), comprising various evaporation zones separated by separating partitions (14) into several distinct elementary chambers (12A, 12B, , 12N) enabling fractionated evaporation through outlets S1, S2, Sn generating a plurality of separate flows of vapour specific to each constituent. The solution (SO) is injected into the first chamber (12A) subjected to the lowest temperature T1, so as to impregnate a mobile porous element (16), which passes through the various partitions (14), while being successively in contact with said chambers heated at increasing temperatures T1, T2, , Tn. A neutral carrier gas (GV) is injected in the vicinity of the partitions (14) for controlling of pressure losses in the gas flows between the different chambers.
Un dispositif d'évaporation 10 d'une solution SO liquide à base de solvant et de composés ou solutés au sein d'une enveloppe (11, 111, 211 ), comporte différentes zones d'évaporation compartimentées par des cloisons 14, de séparation en plusieurs enceintes 12A, 12B... 12N élémentaires distinctes permettant une évaporation fractionnée à travers des sorties S1, S2, Sn générant une pluralité de flux séparés de vapeur spécifique à chaque constituant. La solution SO est injectée dans la première enceinte 12A soumise à la température T1 la plus basse, de manière à imbiber un élément mobile 16 poreux, lequel traverse les différentes cloisons 14, en étant successivement en contact avec lesdites enceintes chauffées à des températures T1, T2,... Tn croissantes. Un gaz vecteur GV neutre est injecté au voisinage des cloisons 14 pour un contrôle des pertes de charge des écoulements de gaz entre les différentes enceintes.
