Patent

CA 2222084

A mass- and heat-exchange device for a distillation column, in particular a cryogenic distillation column, comprises several horizontal layers of stationary ventilators (1A, 1B). The ventilators are stacked in successive horizontal layers within which each deflector forms part of two adjacent ventilators rotating in opposite directions. The layers are formed by the juxtaposition of strips obtained from sheets by cutting and folding and/or bending and/or twisting and are particularly simple to manufacture.

Échangeur de chaleur et de masse pour une colonne de distillation, en particulier une colonne de distillation cryogénique. L'échangeur comprend plusieurs rangées horizontales de ventilateurs stationnaires (1A, 1B). Les ventilateurs sont superposés en rangées horizontales successives à l'intérieure desquelles chaque déflecteur fait partie de deux ventilateurs adjacents tournant dans des directions opposées. Les rangées sont formées par la juxtaposition de bandes obtenues de feuilles coupées, et repliées ou pliées ou torsadées et leur fabrication est particulièrement simple.
