Description
(54) КОЖУХОТРУБНЫЙ ТЕПЛООБМЕННИК(54) SHELL-TUBE HEAT EXCHANGER
1one
Изобретение касаетс кожухотрубных теплообменников, в которых среда, протекающа по трубам, охлаждает или нагревает несколько других сред, циркулирующих в межтрубнсм пространстве.The invention relates to shell-and-tube heat exchangers in which the medium flowing through the pipes cools or heats several other fluids circulating in the inter-tube space.
Известны кожухотрубные теплообменники , содержащие кожух с торцовыми коллекторами и боковыми штуцерами и соосно размещенные в кожухе наружньй и внутренний кольцевые пучки.труб, укрепленные в трубных досках, подключенные к коллекторам, и отделенные один от другого цилиндрической обечайкой 1 .Known shell-and-tube heat exchangers, containing a casing with end headers and side fittings and outer and inner ring bundles coaxially housed in the casing, are reinforced in tube sheets, connected to the collectors, and separated from one another by a cylindrical shell 1.
Однако такой теплообменник не может обеспечить в межтрубном пространстве циркул цию двух различных рабочих сред.However, such a heat exchanger cannot ensure the circulation of two different working media in the annular space.
Целью изобретени вл етс повышение компактности при организации циркул ции двух сред с различными давлени ми в межтрубном пространстве.The aim of the invention is to increase the compactness when organizing the circulation of two media with different pressures in the annular space.
Это достигаетс тем, что в предложенном теплообменнике кажда трубна доска выполнена составной с кольцевыми буртами в месте сочленени , между которыми закреплена цилиндрическа обечайка, и по оси внутреннего пучка установлен дополнительный коллектор дл одной из сред межтрубного пространства с перепускньли клапаном внутри, раздел ющим коллектор на раздающую и приемную полости, соединенные окнами с межтрубным пространством внутреннего пучка, причем дополнительный коллектор выведен за пределы торцовых коллекторов.This is achieved by the fact that in the proposed heat exchanger, each tube plate is made integral with annular shoulders at the junction, between which a cylindrical shell is fixed, and an additional collector is installed along the axis of the internal beam for one of the annular media with a relief valve inside that separates the collector and the receiving cavity, connected by windows with the annular space of the inner beam, with an additional collector output beyond the limits of the end collectors.
На чертеже схематически изображен предложенный теплообменник.The drawing schematically shows the proposed heat exchanger.

Теплообменник имеет кожух 1 с торцовыми коллекторами 2 и 3 и боковыми штуцерами 4 и 5. В кожухе 1 размещены кольцевые пучки 6 и 7 труб, укрепленные в трубных досках 8 и 9 и отде5 ленные один от другого цилиндрической обечайкой 10. Кажда трубна доска выполнена составной с кольцевыми буртами 11 и 12 вместе сочленени , между которьми закреплена обечайка 10. The heat exchanger has a casing 1 with face collectors 2 and 3 and side fittings 4 and 5. The casing 1 contains annular bundles of 6 and 7 pipes fixed in tube plates 8 and 9 and separated from one another by a cylindrical shell 10. Each tube plate is made of composite with annular shoulders 11 and 12 together of the joint, between which the shell 10 is fixed.
0 По оси внутреннего кольцевого пучка 7 установлен дополнительный коллектор 13 дл одной из сред межтрубного пространства с перепускньм клапаном 0 An additional collector 13 is installed along the axis of the inner annular bundle 7 for one of the annular space media with a bypass valve.
5 14 внутри,раздел ющим коллектор на приемную полость 15 и раздающую полость 16, соединенные соответственно окнами 17 и 18 с межтрубным пространством 19 пучка 7. Коллектор 13 выведен за пределы коллекторов 2 и 3.5 14 inside, which separates the collector into the receiving cavity 15 and the dispensing cavity 16 connected by windows 17 and 18 respectively to the annular space 19 of the bundle 7. The collector 13 is led out of the limits of the collectors 2 and 3.
