GAS FILTRATION STRUCTURE WITH ASYMMETRICAL HEXAGONAL CHANNELS

摘要

The invention relates to a structure for filtering particle-laden gases, 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 uniform 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 0 and lower than 1.
