Abstract
Device for drying gas includes a dryer with a vessel which has at least three compartments at a first axial end of a rotor rotatably disposed in the vessel, the rotor arranged for conduction of at least three gas flows, including a main flow, a regeneration flow and a cooling flow, respectively. A first compartment of the vessel has an outlet for said main flow, a second compartment has an inlet for the cooling flow and a third compartment has an inlet for the regeneration flow. The vessel at the second axial end of the rotor has a first compartment which includes an inlet for the main flow and a second compartment with an outlet for the cooling flow and the regeneration flow.
Claims10
Device for drying gas, comprising:
- a dryer vessel having a rotatably mounted rotor therein which contains a drying agent and a driving device arranged to rotate said rotor, said drying agent, upon rotation of the rotor, being successively moved through a drying zone, a regeneration zone and a cooling zone of the vessel;
- said vessel being divided, at a first axial end of the rotor, into at least three compartments for guiding at least three gas flows;
- said gas flows comprising a main flow, a regeneration flow, and a cooling flow;
- a first of said compartments comprising a main outlet for said main flow, a second of said compartments comprising an inlet for the cooling flow, and a third of said compartments comprising an inlet for the regeneration flow;
- said vessel further comprising at least two additional compartments at a second axial end of the rotor;
- a first of said additional compartments comprising an inlet for the main flow and a second of said additional compartments comprising a common outlet for the cooling flow and the regeneration flow;
- said second compartment at the first end of the rotor comprising an additional outlet for the main flow and including two sub-compartments;
- a first of said sub-compartments comprising said inlet for the cooling flow and a second of said sub-compartments comprising said additional outlet for the main flow;
- said two sub-compartments being connected to and in communication with each other.
