摘要： The invention relates to a structure for filtering gases charged with particles, of the honeycomb type and including an assembly of longitudinal adjacent channels with parallel axes and separated by porous filtration walls, in which: each outlet channel has a wall that is common with six inlet channels, each common wall defining a side of said outlet channel; each outlet channel includes six sides having a substantially identical width a in order to define a channel having a substantially hexagonal and regular section; at least two adjacent sides of each inlet channel have a different width; and at least two inlet channels sharing a wall with a same outlet channel, share a common wall having a width b, wherein the ratio between the widths b/a is higher than 1 and lower than 13.

摘要： The subject of the invention is a structure for filtering particle-laden gases, of the honeycomb type and comprising a set of longitudinal adjacent channels of mutually parallel axes (21, 22) separated by porous filtering walls (23), the said channels (21, 22) being alternately plugged at one or other of the ends of the structure so as to define inlet channels (21) and outlet channels (22) for the gas that is to be filtered, and in such a way as to force the said gas to pass through the porous walls (23) that separate the inlet (21) and outlet (22) channels, the said structure being such that in cross section: - the ratio R between the sum of the areas of the inlet channels and the sum of the areas of the outlet channels is greater than 1, - at least some of the porous walls (23) have undulations such that they are concave with respect to the centre of the inlet channels (21) and convex at their middle with respect to the centre of the outlet channels (22), - the outlet channels (22) have at least one rounded corner (25).

摘要： The invention relates to a structure for filtering gases laden with particulates, of the honeycomb type and comprising a set of longitudinal adjacent channels of mutually parallel axes separated by porous filtering walls, said channels being alternately blocked off at one or other of the ends of the structure so as to define entry channels and exit channels for the gas to be filtered, and so as to force said gas to pass through the porous walls separating the entry and exit channels, said structure being characterized in that the entry and exit channels share between them at least one wall having an average thickness d which is constant over the entire length of the filter structure, in that the entry or exit channels share between them at least one wall having an average thickness e which is constant over the entire length of the filter structure and in that the ratio e/d is strictly greater than 1.
