Title
(EN) TUBULAR CHANNEL DIFFUSION DEVICE HAVING FLOW GUIDES THEREIN
(FR) DISPOSITIF DE DIFFUSION PAR CANAUX TUBULAIRES AYANT DES GUIDES D'ECOULEMENT INTERNES
Abstract
(EN)
A diffusion membrane unit (10) comprises a plurality of capillary membrane fluid flow tubes (12). An elongated flow guide member (14) is positioned within the capillary membrane tubes, with the flow guide member defining at least one radial fin (18) positioned longitudinally along the axes of the flow tubes. The radial fin defines a helical relation along its length, whereby fluid passing through the capillary membrane tubes is impelled to flow in a helical path, for increased mixing of the liquid in the capillary membrane tubes.
(FR)
Une unite a membranes de diffusion (10) comprend une pluralite de tubes d'ecoulement de fluides a membranes capillaires (12). Un organe de guidage d'ecoulement allonge (14) est positionne dans les tubes a membranes capillaires, l'organe de guidage d'ecoulement definissant au moins une ailette radiale (18) positionnee longitudinalement le long des axes des tubes d'ecoulement. L'ailette radiale definit une relation helicoidale suivant sa longueur, de telle sorte que le fluide passant au travers des tubes a membranes capillaires est force de s'ecouler suivant un chemin helicoidal, ameliorant le melange du liquide dans les tubes a membranes capillaires.
