HONEYCOMB STRUCTURE AND EXHAUST GAS PURGING DEVICE
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.
本发明提供蜂窝结构体及废气净化装置，该蜂窝结构体能够利用电加热将碳微粒等燃烧除去，并且，抑制了压力损失增加。一种蜂窝结构体，其是柱状的蜂窝结构体，该柱状的蜂窝结构体具有：多孔质的隔壁及位于最外周的外周壁，该隔壁区划形成从流体的流入侧的端面即流入端面延伸至流体的流出侧的端面即流出端面的多个隔室，该隔室形成流体的流路，其中，隔室包括：流体的流入侧呈开口而在流体的流出侧的端面具有封孔部的多个隔室A、以及与隔室A分别交替地配置的且流体的流出侧呈开口而在流体的流入侧的端面具有封孔部的多个隔室B，隔室A的封孔部及隔室B的封孔部中的一者或两者包含磁性体。
