Exhaust gas purifying system, method for manufacturing an exhaust gas purifying system and exhaust gas purifying method using an exhaust gas purifying system

摘要

An object of the present invention is to provide an exhaust gas purifying system (100) that allows a holding stealing material (140) to sufficiently hold an exhaust gas treating body (120) while exhaust gases are flowing therein. Said holding sealing material (140), which is formed into a mat shape containing inorganic fibers, has a first side face (141) positioned on the gas outlet side (112) of the exhaust gas purifying apparatus (110) and a second side face (142) positioned on the gas inlet side (111) of the exhaust gas purifying apparatus (110) with the first side face (141) of the holding sealing material (140) having a first slanting face formed thereon, and on the second side face (142) of the holding sealing material (140), a second slanting face is formed.
