APPARATUS FOR DRYING COMPRESSED AIR Russian patent published in 1994 - IPC

FIELD: drying compressed air. SUBSTANCE: compressed air stream enters dehumidifier 1 wherein moisture is partially separated from it. On leaving the dehumidifier the compressed air stream is branched into two streams. One of the streams enters heat exchanger 3 wherein it is cooled and further condensed. An additional moisture, so formed, is separated in dehumidifier 2. The other stream is fed to the inlet means of vortical tube 4. The cold air stream of tube 4 via heat exchanger 3 is admitted to the passive nozzle of ejector 5. The hot air stream leaving tube 5 is admitted to the active nozzle of ejector 5. Mixing chamber of ejector 5 is connected to the hot end of vortical tube 4 in alignment with its axis. The remainders of the hot and cold streams are exhausted to the environment via regulator valves 6 and 7. EFFECT: intensified air drying. 2 cl, 1 dwg
