Abstract
Abstract Means for drying compressed air in which the hot compressed air is cooled in a condenser to condense moisture and a main stream passed through preferably a rotary sorber partitioned into a main drying zone while a side stream is heated and passed through a rotary partitioned regeneration zone, the regeneration gas after cooling being recycled to the main stream or separately dried.

Total Claims: 4
Claim 1
Independent Claim
157 words
Apparatus for compressing and drying of air comprising a compressor and a condenser, means for cooling the condenser, means for passing warm compressed air to said condenser for condensing moisture therein, a rotary moisture sorption device having a main drying section, a secondary drying section and a regeneration section operative in sequence as said rotary device rotates, means for passing cooled air from which the moisture is condensed from said condenser in a main stream to the main drying section of said rotary sorption device, means for separating a side stream from said main stream, means for heating said side stream, and passing said side stream through said regeneration section for regenerating the same, means for cooling and condensing moisture from the moisture-laden air evolved from said regeneration section and passing said cooled regeneration air to said secondary drying section and means for returning said dried secondary section air and said regeneration air to said main stream.
Claim 2
Dependent Claim

Apparatus for compressing and drying of air comprising a compressor and a condenser, means for cooling the condenser, means for passing warm compressed air to said condenser for condensing moisture therein, a rotary moisture sorption device having a main drying section, a secondary drying section and a regeneration section operative in sequence as said rotary device rotates, means for passing cooled air from which the moisture is condensed from said condenser in a main stream to the main drying section of said rotary sorption device, means for separating a side stream from said main stream, means for heating said side stream, and passing said side stream through said regeneration section for regenerating the same, means for cooling and condensing moisture from the moisture-laden air evolved from said regeneration section and passing said cooled regeneration air to said secondary drying section and means for returning said dried secondary section air and said regeneration air to said main stream.
Claim 3
Dependent Claim
172 words
Apparatus for compressing and drying of air comprising a compressor and a condenser, means for cooling the condenser and means for passing warm compressed air to said condenser for condensing moisture therein, a rotary moisture sorption device mounted in a housing provided with flow-through channels and partitioning walls sub-dividing said sorption device into a main drying section, a regeneration air drying section and a regeneration section, means for passing cooled air from which the moisture is condensed from said condenser in a main stream to said main drying section, means for separating a side stream from said main stream, means for heating said side stream and passing the same to said regeneration section, means for passing regeneration air from said regeneration air zone to a condenser, means for passing condensed regeneration air to said partitioned regeneration air drying section in said housing, and means for returning said dried regeneration air evolved from said regeneration air drying section to said main stream after said main stream has passed through said main drying zone.
