Abstract

L'invention concerne un séparateur à lamelles (1) comportant plusieurs lamelles creuses (2) disposées mutuellement parallèles. Respectivement deux lamelles (2) forment un espace d'écoulement (5) parcouru dans une direction d'écoulement (3) par un fluide (4), par exemple par un gaz (4) à déshumidifier contenant une phase liquide (28). Cet espace d'écoulement (5) est délimité sur deux côtés (6) respectivement parallèles à la direction d'écoulement (3) par les deux lamelles respectives (2) disposées mutuellement parallèles. Selon l'invention, les espaces d'écoulement (5) sont fermés de façon supplémentaire sur au moins un autre côté respectif (7) parallèle à la direction d'écoulement (3), par une tôle de fermeture à fentes (20) présentant une pluralité de fentes d'insertion (25) dans lesquelles les lamelles (2) sont insérées. Ainsi, l'espace d'écoulement (5) est fermé (séparation air (11) et côté eau (12)) par rapport à un espace creux respectif (13) des lamelles creuses (2), les lamelles (2) et l'espace creux (13) étant respectivement ouverts sur les côtés parallèles à la direction d'écoulement (3). Ainsi il est possible d'éviter que le fluide (4) s'écoulant dans l'espace d'écoulement n'entraîne du liquide (28) s'accumulant dans l'espace creux (13), notamment sur le côté latéral (34) de la lamelle (2).
