<p>The invention relates to a cellular structure (1) for filtering particle-laden gases, including an assembly of longitudinal adjacent channels (2, 3) having axes that are parallel to one another and separated by porous filtration walls (5), said channels being alternately blocked at one end of the structure or the other, wherein said structure is characterized in that each outlet channel (2) has a wall that is common to six inlet channels (3), each common wall constituting a side of said outlet channel, at least a portion of the outlet channels (3) having an irregular hexagonal cross-section consisting of six sides, at least two adjacent sides (8, 9) having widths of a and a', in that two contiguous inlet channels (3), each sharing a wall (9) having a width a with an outlet channel (2) having an irregular hexagonal cross-section, share a common wall (10) having a width b' therebetween, and in that two contiguous inlet channels (3), each sharing, with said outlet channel (2), walls (8, 9) having a width a and a', respectively, share a common wall (11) having a width b therebetween, the ratio between the widths b'/b being 0.5 to 2.</p> |
