Abstract
(EN)
Provided are a honeycomb structure and an exhaust gas purging device that are capable of burning off and removing carbon particulates through electric heating and that exhibit suppression of increase in pressure loss. This columnar honeycomb structure has: porous partition walls that demarcate and form a plurality of cells serving as flow channels for a fluid and each extending from an inflow end surface being the end surface of the fluid inflow side to an outflow end surface being the end surface of the fluid outflow side; and an outer peripheral wall located at the outermost periphery. The cells include: a plurality of cells A that are each open on the fluid inflow side and each have an opening-sealed part at the end surface of the fluid outflow side; and a plurality of cells B that are alternately arranged with respect to the cells A, are each opened on the fluid outflow side, and each have an opening-sealed part at the end surface of the fluid inflow side. One or both of the opening-sealed part of each of the cells A and the opening-sealed part of each of the cells B include a magnetic body.

L'invention concerne une structure en nid d'abeilles et un dispositif de purge de gaz d'échappement qui sont capables de brûler et d'éliminer des particules de carbone par chauffage électrique et qui présentent une suppression d'augmentation de perte de pression. Cette structure en nid d'abeilles colonnaire comprend : des parois de séparation poreuses qui délimitent et forment une pluralité de cellules servant de canaux d'écoulement pour un fluide et s'étendant chacune à partir d'une surface d'extrémité d'entrée qui est la surface d'extrémité du côté entrée de fluide à une surface d'extrémité de sortie qui est la surface d'extrémité du côté sortie de fluide ; et une paroi périphérique externe située au niveau de la périphérie la plus à l'extérieur. Les cellules comprennent : une pluralité de cellules A qui sont chacune ouvertes sur le côté entrée de fluide et comportent chacune une partie à ouverture scellée au niveau de la surface d'extrémité du côté sortie de fluide ; et une pluralité de cellules B qui sont agencées en alternance par rapport aux cellules A, sont chacune ouvertes sur le côté sortie de fluide, et comportent chacune une partie à ouverture scellée au niveau de la surface d'extrémité du côté entrée de fluide. L'une ou les deux parties à ouverture scellée de chacune des cellules A et la partie à ouverture scellée de chacune des cellules B comprennent un corps magnétique.
