Patent

CA 2274697

A fluids contacting column (50) includes a perforated cover plate (21) positioned over a tray opening (10) and secured within the opening (10). Deflecting members (224, 225, 226) span each perforation (200, 201, 202) in the cover plate (21) to prevent bleed fluid from shooting straight up and hitting the underside of the above tray (1). The deflecting members (224, 225, 226) also provide a surface for dispersing lighter, finer bleed fluid (11) flowing upwardly through the perforations (200, 201, 202) over a central zone of the cover plate (21) and into heavier fluid flowing across the nay (1) in the path of the cover plate (21). The cover plate (21) is positioned over the tray opening (10) by legs (23) which are integral with the cover plate (21) and may be fixed or slidable within the tray opening (10).

L'invention concerne une colonne (50) de mise en contact de fluides comprenant une plaque de fermeture (21) perforée disposée sur une ouverture (10) de plateau et fixée dans l'ouverture (10). Des éléments de déviation (224, 225, 226) enjambent chaque perforation (200, 201, 202) dans la plaque de fermeture (21) pour empêcher un fluide prélevé de jaillir vers le haut et de toucher le côté inférieur du plateau (1) se trouvant au-dessus. Les éléments de déviation (224, 225, 226) forment également une surface de dispersion du fluide prélevé (11) plus léger et plus fin, s'écoulant vers le haut par les perforations (200, 201, 202) sur une zone centrale de la plaque de fermeture (21) et se mélangeant à un fluide plus lourd s'écoulant sur le plateau (1) dans la trajectoire de la plaque de fermeture (21). La plaque de fermeture (21) est maintenue sur l'ouverture du plateau (10) par des pieds (23) intégrés à la plaque de fermeture (21) et pouvant être fixes ou glisser dans l'ouverture (10) du plateau.
