<p>The invention relates to a honeycomb structure for the filtration of particle-laden gases, comprising a periodic set of adjacent channels (21, 22) separated by portions of porous filter walls (23), said structure being such that in cross-section each porous filter wall (23) has: a first core (26) which corresponds to a continuous periodic curve of the same period as that of the channels, being superimposed at each wall portion (24) of a first population with the midline of said portion (24); and a second core (27) which corresponds to a continuous periodic curve of the same period as that of the channels, being superimposed at each wall portion (25) of a second population with the midline of said portion (25), each of the two cores (26, 27) of each wall (23) being a translation of the other by a non-zero distance d.</p> |
