COMPRESSED AIR DRYING APPARATUS Russian patent published in 2003 - IPC

FIELD: compressed air treatment systems including its drying apparatuses. SUBSTANCE: apparatus has inlet and outlet pipelines, two different heat exchangers, bypass pipe with moisture separating header, and steam trap. First heat exchanger is, essentially, single-row frame-mounted tubular radiator blown down with atmospheric air forced by fan connected to single-row tubular radiator via flexible link. Second heat exchanger is set of heat-transfer components of tube-in-tube type. It is connected to single-row tubular radiator of first heat exchanger through upper header of second heat exchanger and through bypass pipe accommodating moisture separating header in its lower part; this header communicates with first heat exchanger and with steam trap. EFFECT: enhanced heat-transfer efficiency; reduced metal input and size, facilitated installation and maintenance. 4 cl, 3 dwg
