EXHAUST GAS CLEANING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a technology for cleaning exhaust gas which hardly causes breakage of a heating element even when high voltage power source is used and can reduce size of the heating element.

SOLUTION: An exhaust gas cleaning system includes: a heating part that is provided to the exhaust path of the exhaust gas and can heat the exhaust gas; and a catalyst part which is provided to the downstream side of the heating part in the exhaust path and where a catalytic reaction for reducing a specific material contained in the exhaust gas is carried out. The heating part 1 includes: a honeycomb structure having partition walls 7 essentially composed of ceramics and heated by energization of power and a plurality of cells 5 divided and formed by the partition walls 7 to become the flow passages of the exhaust gas; and a pair of electrode parts 4 to be an anode 4a and a cathode 4b which are arranged to be in contact with the honeycomb structure to energize the partition walls 7 of the honeycomb structure.
