Abstract
Abstract The present invention relates to an organic-solvent vapor adsorbing apparatus which includes a rotor containing an adsorbent and having tubular draft passages arranged in a direction of the rotational axis thereof. Plate-like separators disposed along a radial direction of the rotor define a plurality of zones. A treatment zone is provided for removing organic solvent vapor from a gaseous stream passed therethrough and into the adsorbent. A regeneration zone is also provided for removing the organic solvent from the adsorbent by a heated air stream passed therethrough. Finally, a purge zone is provided for cooling the adsorbent with cool air. Air exiting the purge zone is merged with the heated air stream which is introduced into the regeneration zone.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
192 words
An organic-solvent vapor adsorbing apparatus comprising: a rotor having end faces, a rotational axis, and draft passages which are arranged in a direction of said rotational axis and which define a honeycomb structure; an adsorbent for adsorbing organic-solvent vapor, said adsorbent being contained in said rotor; a rotatively driving mechanism for imparting rotational movement to said rotor; separators for partitioning each of said end faces of said rotor into a plurality of regions, including: a treatment region which is constructed and arranged to receive air to be treated and to discharge treated air; a regeneration region which is constructed and arranged to receive regenerating heated air, to supply said regenerating heated air to said adsorbent for removing organic-solvent vapor from said adsorbent, and to discharge said regenerating heated air; and a purge region which is constructed and arranged to receive purged air for cooling said adsorbent and to discharge said purged air; and means for supplying said purged air discharged from said purge region into said regeneration region, wherein said treatment region, said regeneration region, and said purge region are arranged sequentially in a direction of the rotational movement of said rotor.
