Abstract

Le filtre décrit (1), qui sert à séparer des particules à partir de gaz par criblage, comprend des éléments de filtrage en forme de sacs (7) qui sont fabriqués à partir d'un matériau de filtre et qui comportent chacun au moins une ouverture pour la décharge des gaz s'écoulant à travers le matériau de filtre des organes de filtrage. Le filtre (1) comprend en outre des organes raidisseurs perméables disposés à l'intérieur des éléments de filtrage. Les faces extérieures des éléments de filtrage (7) sont pourvues de fibres (13) suspendues flottantes au matériau de filtrage ainsi que des organes électroconducteurs (8) disposés à l'intérieur et/ou à l'extérieur des éléments de filtrage et servant à charger lesdites fibres.
