Abstract

1345368 Heat exchanger STEIN INDUSTRIE 19 April 1971 [6 March 1970] 24318/71 Heading F4A A heat exchanger comprises a plurality of tubes 2 for a first fluid connected between two tube plates 4, 5 in a shell 1 for a second fluid, each tube having at one end a rectilinear portion followed by an expansion bend 18, the tubes being in two groups 2a, 2b the tubes in each group being arranged in parallel equi-spaced rows and parallel equi-spaced lines perpendicular to the rows, the two groups lying on respective sides of a line parallel to the said lines and the rows of one group being offset with respect to those of the other group so that the expansion bend of each tube extends in the plane of the row containing that tube and between adjacent rows of the other group. The first and second fluids are preferably water and liquid sodium, the latter entering or leaving through a pipe 7 located so that the sodium does not circulate around the bends. The upper parts of the tubes 2 are more closely spaced, are surrounded by a sleeve 14 and act as a superheater section.

Description

Изобретениеотноситс  к кожухотрубным теплообменникам.The invention relates to shell-and-tube heat exchangers.

Известны кожухотрубные теплообменники с внутренней обечайкой, размещенной с зазором относительно двухсекционного пучка труб, имеющих дугообразный гиб.Known shell-and-tube heat exchangers with an inner shell, placed with a gap relative to the two-section tube bundle, having an arc-shaped bend.

Цель изобретени  - повышение эффективности компенсации температурных расширений и коМЛактности.The purpose of the invention is to increase the efficiency of compensation for temperature expansions and cMLT.

В предлагаемом теплообменнике трубы в разных секци х смещены на полшага и в зоне гиба вход т в межтрубное пространство смежных секций с образованием колен, перпендикул рно расположенных к оси пучка. In the proposed heat exchanger, the pipes in different sections are shifted by half a step and, in the bending zone, enter the annular space of the adjacent sections with the formation of elbows perpendicular to the beam axis.

Внутренн   обечайка может быть установлена над зоной гиба труб.The inner shell can be installed above the pipe bending zone.

Дл  использовани  теплообменника в качестве парогенератора в зоне перегрева пара трубы в пучке размещены с меньшим шагом, чем в испарительной зоне.To use the heat exchanger as a steam generator in the overheated zone of steam, the pipes in the beam are placed with a smaller pitch than in the evaporation zone.

На фиг. 1 изображен оп-исываемый теплообменник , вертикальный разрез; на фиг. 2 - разрез но А-А на фиг. 1.FIG. 1 shows an opted heat exchanger, vertical section; in fig. 2 is a section along the line A-A in FIG. one.

Теплообменник содержит кожух 1, внутреннюю обечайку 2, размещенную с зазором относительно двухсекционного пучка труб 3, имегош,11х- дугообразный гиб. Трубы в разйых секци х смещены на полшага и в зоне гиба вход т в межтрубное пространство смежныхThe heat exchanger contains a casing 1, the inner shell 2, placed with a gap relative to the two-section tube bundle 3, has a 11x arc-shaped bend. The pipes in the razykh sections are shifted by half a step and in the bend zone they enter the annular space of the adjacent

секций с образованием колен 4 и 5, пер ендикул рно расположенных к оси пучка.sections with the formation of elbows 4 and 5, which are alternately arranged to the beam axis.

Внутренн   обечайка установлена над зоной гиба труб, что способствует циркул ции теллоносител  в сторону от указанной зоны.The inner shell is installed above the bend zone of the pipes, which contributes to the circulation of the solid carrier away from the specified zone.

Дл  использовани  теллообменника в качестве парогенератора в зоне б перегрева пара трубы в пучке размещены с меньшим шагом , чем в испарительной зоне.In order to use the body exchanger as a steam generator in the zone b, the superheated steam of the pipe in the bundle is placed with a smaller pitch than in the evaporation zone.
