摘要
缠绕管式换热器是一种结构紧凑的高效换热设备,具有管束补偿性好、管内的操作压力高、可同时实现多股流的热交换等优点,广泛应用于煤气化废热回收、空气分离、氢液化、稀有气体分离、低温甲醇洗、液氮洗等领域。本文着重介绍了缠绕管式换热器的结构、优点、缺点以及国内的发展情况。
The coil tube heat exchanger is a highly effective heat exchanging device with compact structure. With good tube bundle compensation, high operation pressure inside the tube and good heat exchanging ofmulti-flow, the coil tube heat exchanger is widely used in the fields of. gasification waste heat recovery, air separation, hydrogen liquation, separation of rare gas, Rectisol process, liquid nitrogen wash and coalgasification. This article focused on the structure, merits, demerits of the coil tube heat exchanger and the developments made both in China and abroad.
