CERAMIC HONEYCOMB FILTER AND EXHAUST GAS CLEANING APPARATUS

摘要

PROBLEM TO BE SOLVED: To solve such a problem that it is difficult to collect particulate matter in high collection efficiency in the case of the conventional ceramic honeycomb filter having such a structure that exhaust gas is made to pass through a pore formed on a partition wall of a porous ceramic honeycomb structure by sealing a flow passage of the porous ceramic honeycomb structure.

SOLUTION: In the ceramic honeycomb filter having such the structure that exhaust gas is made to pass through the pore formed on the partition wall of the porous ceramic honeycomb structure by sealing the flow passage of the porous ceramic honeycomb structure, the sealed part at least on the exhaust gas outflow side is arranged apart from the end face on the exhaust gas outflow side of the ceramic honeycomb filter.
