Abstract

L'invention a pour objet une structure de filtration de gaz chargés en particules en nid d'abeilles et comprenant un ensemble périodique de canaux (21, 22) adjacents séparés par des portions de parois poreuses filtrantes (23), ladite structure étant telle qu'en coupe transversale chaque paroi poreuse (23) possède une première âme (26), qui correspond à une courbe périodique continue de même période que celle des canaux, se superposant, au niveau de chaque portion de paroi (24) d'une première population, avec la ligne médiane de ladite portion (24), et une deuxième âme (27), qui correspond à une courbe périodique continue de même période que celle des canaux, se superposant, au niveau de chaque portion de paroi (25) d'une deuxième population, avec la ligne médiane de ladite portion (25), les deux âmes (26, 27) de chaque paroi (23) étant chacune une translation de l'autre d'une distance d non-nulle.The invention relates to a structure for filtering gases charged with honeycomb particles and comprising a periodic assembly of adjacent channels (21, 22) separated by porous filtering wall portions (23), said structure being such that in cross-section, each porous wall (23) has a first core (26), which corresponds to a continuous periodic curve of the same period as that of the channels, superimposed at each wall portion (24) of a first population, with the median line of said portion (24), and a second core (27), which corresponds to a continuous periodic curve of the same period as that of the channels, superimposed, at each wall portion (25) d a second population, with the median line of said portion (25), the two cores (26, 27) of each wall (23) being each a translation of the other by a distance d non-zero.
