REGENERABLE AIR PURIFICATION SYSTEM

摘要

An air purification system for removing chemical contaminants from an air stream. The air purification system includes an adsorbent filtration material that is regenerable by the application of increased temperature air. In one embodiment, the adsorbent filter is a packed bed that is regenerated by the use of a heater. In another embodiment, the adsorbent filter is a rotating wheel having an adsorption segment where contaminants are removed from an air stream. The wheel also includes a cooling segment and a regeneration segment. Air is passed over the cooling segment to preheat regeneration air and to reduce the temperature of the filter wheel. Regeneration air is further heated by a heater and then passed through the regeneration segment to regenerate the filter.
