Abstract

L'invention a pour objet une structure de filtration de gaz chargés en particules, du type en nid d'abeilles et comprenant un ensemble de canaux adjacents longitudinaux d'axes parallèles entre eux (21, 22) séparés par des parois poreuses filtrantes (23), lesdits canaux (21, 22) étant alternativement bouchés à l'une ou l'autre des extrémités de la structure de façon à définir des canaux d'entrée (21 ) et des canaux de sortie (22) pour le gaz à filtrer, et de façon à forcer ledit gaz à traverser les parois poreuses (23) séparant les canaux d'entrée (21 ) et de sortie (22), ladite structure étant telle qu'en coupe transversale : - le rapport R entre la somme des aires des canaux d'entrée et la somme des aires des canaux de sortie est supérieur à 1, - au moins une partie des parois poreuses (23) présentent des ondulations de façon à être concaves par rapport au centre des canaux d'entrée (21 ) et convexes en leur milieu par rapport au centre des canaux de sortie (22), - les canaux de sortie (22) possèdent au moins un coin arrondi (25).
