Abstract
The invention relates to a structure for filtering particle-laden gases, comprising an assembly of elements of the honeycomb type linked by a joint or seal, each element incorporating a set of adjacent ducts or channelsof mutually parallel axes and separated by porous walls, which ducts are closed off by plugs at one or other of their ends so as to define entry chambers that open onto a gas intake face and exit chambers opening onto a gas discharge face, in such a way that the gas to be filtered passes through the porous walls, said structure being characterized in that its geometrical centre, in a cross section of the structure perpendicular to its main axis, does not correspond to a symmetry element of an element or of a group of elementsin the assembly.
