Abstract

L'invention concerne un dispositif filtrant (100) en particulier à deux étages pour la séparation de particules liquides et/ou solides d'un flux gazeux à épurer. Le dispositif filtrant selon l'invention comprend de préférence un pré-séparateur cyclone (10) qui est réalisé en tant que préfiltre et qui sépare les particules du flux gazeux dans un premier étage en mettant le flux gazeux en rotation, ainsi qu'un élément filtrant principal (20) qui est placé en aval dans le sens d'écoulement du flux gazeux et qui sépare les particules du flux gazeux dans un deuxième étage en conduisant les particules à travers au moins un milieu filtrant (24), l'élément filtrant principal (20) étant logé dans un boîtier de filtre (30) qui présente une entrée (32) côté non filtré reliée au pré-séparateur cyclone (10) et une sortie (34) côté filtré pour le flux gazeux à épurer. L'invention vise à améliorer un tel dispositif filtrant de sorte que l'élément filtrant principal (20) soit logé dans le boîtier de filtre (30) sans possibilité de mouvement. A cet effet, pour stabiliser sa position dans le boîtier de filtre (30), l'élément filtrant principal (20) présente au moins un élément de maintien (22) qui s'étend d'un bord périphérique de l'élément filtrant principal (20) vers le boîtier de filtre (30) et qui positionne l'élément filtrant principal (20) à une distance définie du boîtier de filtre (30).
