摘要： An atmospheric-vacuum heat exchange system with a winding-tube heat exchanger, has a first and second heat exchanging group; a primary distillation tower (4) or flash tower; an atmospheric furnace (5); an atmospheric tower (6); a vacuum furnace (7) and a vacuum tower (8); each winding-tube heat exchanger has a shell-pass cylinder (370), a first and second shell-pass connecting tube (371,372), a first and second tube plate (330,340), a plurality of first and second tube box (310,320), a plurality of heat exchange tubes (360) spirally wounded with multiple spiral tube layers; the number of the first and second tube box (310, 320) are respectively N, and each spiral tube layer has N group(s) of the wounded heat exchange tubes (360), N is a natural number greater than or equal to 1. The loss of heat exchanger is reduced.
