Title (EN) DEVICE FOR SEPARATING PARTICLES FROM A GAS
(FR) DISPOSITIF POUR LA SEPARATION DES PARTICULES DE POUSSIERES CONTENUES DANS UN GAZ
Abstract:
(EN) A device for separating particles from a gas by screening, comprising a bag-shaped, elongate filter member (5), such as a filter bag or a filter cell, at least three longitudinal, substantially parallel rods (10) positioned at a distance from each other adpated to the inner dimensions of the filter member in the expanded state thereof, and transverse stiffening means (7) for fixing the distance between the rods. The rods (10) further cooperate with means (6) arranged on the surface of the filter member (5), for fixingly receiving the rods.
(FR) Le dispositif décrit, qui sert à séparer les particules de poussières contenues dans un gaz par criblage, comprend un filtre allongé en forme de sac (5) constitué par exemple par un filtre à sac ou à cellule, au moins trois tiges longitudinales sensiblement parallèles (10) disposées à une certaine distance entre elles et adaptées aux dimensions internes du filtre à l'état expansé, ainsi qu'un organe de rigidification transversale (7) qui sert à maintenir fixe la distance entre les tiges. Les tiges (10) coopèrent en outre avec un organe (6) placé sur la surface du filtre (5) et servant à recevoir les tiges en position fixe.
