Method for cleaning exhaust air from e.g. chemical industry, into atmosphere, involves heating exhaust air above specific degree, and containing catalytic oxidation in exhaust air caused when dioxygen is contained in exhaust air

摘要

The method involves subjecting exhaust air and ozone to a catalysis treatment. The exhaust air is heated up to a temperature above 100 degree Celsius. A catalytic oxidation of contamination contained in the exhaust air is caused when dioxygen is contained in the exhaust air. The catalytic oxidation takes place at a processing temperature within a range of 100 to 200 degree Celsius. Process heat developing from the catalytic oxidation is used by a heat exchanger (10) for heating supplied exhaust air.
