PLANT FOR COMPRESSED AIR PRE-CONDITIONING Russian patent published in 2003 - IPC

FIELD: industry equipment, particularly for compressed gas dehydration by removal of condensed moisture with the use of ambient atmosphere cold. SUBSTANCE: plant comprises modular dehydrators mounted on common base. Modular dehydrators are united into bank by overflow distribution chambers having air feeding and air extraction joining pipes and condensate collector. Each dehydrator has supplying dehumidifying collector, receiving dehumidifying collector, separating dehumidifying collector and tube-in-tube heat-exchanger system, which connects dehydrator collectors. Collector has multi-body performance with wet and dry compartments located into separate bodies. Dry compartments are connected with collectors by ends of heat-exchanger outer tubes. Collectors are connected with dry compartments by ends of heat-exchanger inner tubes. Separating dehumidifying collector dry compartment is located at a distance from wet compartment and joined with wet compartment by inner tubes flange connection. Dry compartment L-shaped channel is connected with wet compartment by flange connection. Receiving dehumidifying collector is mounted at a distance from separating dehumidifying collector and inner pipes are connected by flange connection within the distance. Joining pipes for condensate drainage are arranged in receiving dehumidifying collector lower parts. Air extraction joining pipes position is adjusted in vertical direction relative receiving dehumidifying collector upper pipes in accordance with relation H≥1/2d, where d is receiving dehumidifying collector pipe diameter. EFFECT: increased degree of air dehydration, decreased labor- intensiveness of installation work. 2 dwg
