Claim:
An adsorption drying apparatus, particularly for drying a compressed gas, comprising an adsorption chamber ( 11 ) having a plurality of adsorption conduits ( 101 ) containing an adsorption material ( 123 ), a first feeding line ( 106 ) and a first discharging line ( 109 ) disposed at a first end ( 111 ) of the adsorption chamber ( 11 ), and a second feeding line ( 108 ) and a second discharging line ( 107 ) disposed at a second end ( 112 ) of the adsorption chamber ( 11 ), wherein the adsorption chamber ( 11 ) is rotatable with respect to the feeding and discharging lines ( 106 , 107 , 108 , 109 ), the adsorption conduits being fluidically connectable in temporal alternation with the first feeding line ( 106 ) and the second discharging line ( 109 ) or the first discharging line ( 107 ) and the second feeding line ( 108 ), so that a drying sector ( 102 ) and a regeneration sector ( 103 ) are defined, wherein the gas is dried in the drying sector ( 102 ), and the adsorption material ( 123 ) is regenerated in the regeneration sector ( 103 ), the first feeding line ( 106 ) being configured such that the gas to be dried is feedable to the regeneration sector ( 103 ) as a full flow, the second discharging line ( 107 ) being in communication with the second feeding line ( 108 ) and thus forming a connecting line in which a condenser is provided, a pressure increasing device ( 18 ) provided within the connecting line to increase pressure of the gas flowing from the second discharging line ( 107 ) to the second feeding line ( 108 ), a cooling stream optionally branched off at the first ( 111 ) or second end ( 112 ) of the adsorption chamber ( 11 ), so as to cool the adsorption chamber ( 11 ) within a cooling sector ( 119 ), and the regeneration sector ( 103 ) and the drying sector ( 102 ) being connected in cascade for a serial through-flow, such that a gas stream fed to the drying sector ( 102 ) essentially completely corresponds to a gas stream discharged from the regeneration sector ( 103 ), optionally including the a gas stream discharged from the cooling sector.
