ABSTRACT:
An air cleaner includes first and second support structures connected in series. The first support structure has a coating made of a material which absorbs organic contaminants from air passing through it. A combustion catalyst coats the second support structure. The air cleaner thus removes organic contaminants from the air at ambient temperature, when air passes through the first support structure. When the air cleaner has operated for an extended time, the absorbent coating becomes filled with contaminants. One then regenerates the air cleaner by applying heat to both support structures, to evolve the organic contaminants from the first support structure and to burn off these contaminants catalytically in the second support structure. In one embodiment, the support structure has the form of an electrically heated converter, in which one uses an electric current to provide the heat needed for regeneration. Only a relatively small volume of air becomes heated during regeneration. A suitable system of valves and sensors assures that air flows through the desired paths during the cleaning and regeneration phases. Other embodiments of the invention include a single support structure, which may or may not have a catalyst coating.
