THE INVENTION RELATES TO A FACILITY FOR DRYING COMPRESSED AIR WITH AT LEAST TWO PARALLEL-CONNECTED, DRYING AGENT-FILLED ABSORPTION CONTAINERS (3, 4) WHICH ALTERNATELY ARE DRIVEN IN ABSORPTION OR REGENERATION MODE. THE DRYING AGENT DRIES THE COMPRESSED AIR (8) IN ABSORPTION MODE, THE MOISTURE-LADEN DRYING AGENT IS DRIED FIRST BY DESORPTION AND THEN COOLED WHILE IN REGENERATION MODE. THE DRYING AGENT IS DRIED WITH THE HEAT FOUND IN THE DRIED, MOIST COMPRESSED AIR (8). TO INCREASE THE ENERGY EFFICIENCY OF THE FACILITY AND THE QUALITY OF THE DRIED COMPRESSED AIR (14), THE-INVENTION PROPOSES THAT A STREAM (7) BE BRANCHED OFF OUT OF THE DRIED COMPRESSED AIR AFTER DESORPTION IS DONE IN ORDER TO COOL THE ABSORPTION CONTAINER (4) IN REGENERATION MODE AND THEN TO MIX IN THE DRIED, MOIST COMPRESSED AIR AFTER IT HAS RUN THROUGH THE ABSORPTION CONTAINER (4) IN ABSORPTION MODE. THIS REQUIRES THAT A PUMP TO INCREASE PRESSURE (17) BE PLACED IN THE PARTIAL STREAM CONDUIT (16) BRANCHING OFF FROM OUTLET LINE (15). THIS MAKES IT POSSIBLE TO USE THE COOLING PHASE AS THE SECOND STEP OF THE REGENERATION PROCESS THAT CAN BE CARRIED OUT EVEN IF THERE IS NO AIRFLOW FROM THE PROCESS. |
