FILTER COMPRISING A PLURALITY OF HONEYCOMB ELEMENTS JOINED TOGETHER IN AN OFFSET ASSEMBLY

摘要

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 channels 20 of 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 25, 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 elements 30 in the assembly.
