DEODORIZER FOR EXHAUST GAS

摘要

PROBLEM TO BE SOLVED: To prevent lowering of deodorizing ability of the oxidation combustion catalyst due to the self-heating phenomenon in a deodorizer for exhaust gas using a catalyst oxidation combustion system.

SOLUTION: This deodorizer is provided with a self-heating temperature sensor 30 for detecting atmospheric temperature near an exhaust gas flow side surface of the oxidation combustion catalyst 20. When the self-heating temperature sensor 30 detects a self-heating, heating operation of a heater 21 for heating the oxidation combustion catalyst 20 is stopped to restrict the following self-heating.
