Title
(EN) CROSS FLOW FILTER DEVICE WITH CONCENTRIC FILTER ELEMENTS
(FR) DISPOSITIF DE FILTRE A COURANT TRANSVERSAL AVEC ELEMENTS DE FILTRE CONCENTRIQUES
Abstract
(EN) Cross flow filter device comprising a longitudinal first filter element (1) having a first width (w1) and a longitudinal central axis (8), a longitudinal second filter element (2) having a second width (w2) and being longitudinally installed subst antially concentrically inside said first filter element (1), a housing (3) surrounding said first filter element (1), said cross flow filter device having respectively a raw material inlet (4), a concentrate outlet (5), and a first filtrate outlet (6) connected to said first filter element (1). The ratio between the second width (w2) and the first width (w1) is 65%, preferably at least 70% and more preferably about 75%.
(FR) Cette invention concerne un dispositif de filtre à courant transversal, qui comprend un premier élément de filtre longitudinal (1) ayant une première largeur (w1) et un axe central longitudinal (8), un second élément de filtre longitudinal (2) ayant une seconde largeur (w2) et placé longitudinalement dans une position essentiellement concentrique à l'intérieur du premier élément de filtre (1), un logement (3) entourant le premier élément de filtre (1). Ce dispositif de filtre à courant transversal comporte respectivement une entrée de matière brute (4), une sortie de concentré (5), et une première sortie de filtrat (6) raccordée au premier élément de filtre. Le rapport entre la seconde largeur (w2) et la première largeur (w1) est égal à 65 %, de préférence à au moins 70 % et, plus préférablement, à environ 75 %.
