(54) КОЖУХОТРУБЧАТЫЙ ТЕПЛООБМЕННИК(54) SHELL AND TUBE HEAT EXCHANGER

Изобретение относитс к теплооб|менным annapaTciM и может быть испольэовано в химической и энергетической промышленности.The invention relates to heat exchange annapaTciM and can be used in the chemical and energy industries.

Известны кожухотрубчатые теплообменники , содержащие трубный пучок, закрепленный в трубных решетках и заключенный в шестигранную обечайку , имеющую с кожухом зазор, продольную перегородку, расположенную внутри трубного пучка и прикрепленную одним концом к одной из трубных решеток и патрубки подвода и отвода теплоносител 1.Known shell-and-tube heat exchangers containing a tube bundle fixed in tube grids and enclosed in a hexagonal shell, having a gap with the sleeve, a longitudinal partition located inside the tube bundle and attached at one end to one of the tube grids and inlet and outlet nozzles of the heat carrier 1.

Недостатком известного теплообменника вл етс низка интенсивность теплообмена и необходимость последовательной установки двух теплообменников дл осуществлени процессов .конденсации и охлаждени парогазовой смеси, что повышает металлоем сость установки.A disadvantage of the known heat exchanger is the low intensity of heat exchange and the need for sequential installation of two heat exchangers for carrying out the processes of condensation and cooling of the vapor-gas mixture, which increases the metal content of the installation.

Цель изобретени - интенсификаци теплообмена и уменьшение металлоемкости .The purpose of the invention is to intensify heat transfer and reduce metal consumption.

Поставленна цель достигаетс тем/ что в теплообменнике патрубки размещены с противоположных сторон кожуха , а обечайка расположена между ними , и в зоне патрубков имеет сегментные кромки, примыкающие к кожуху, причем перегородка другим концом прикреплена ко второй трубной решетке и обоими концами, расположенными за пределами обечайки, дополнительно прикреплена к кожуху и кромкам обечайки.The goal is achieved by the fact that in the heat exchanger the nozzles are located on opposite sides of the casing, and the shell is located between them, and in the zone of the nozzles has segmental edges adjacent to the casing, with the other end attached to the wall of the second tube sheet and both ends outside the shell. , additionally attached to the shell and the edges of the shell.

Причем обечайка и перегород:ка выполнены гофрированными, гофры обе10 чайки и перегородки выполнены горизонтальными .Moreover, the shell and the partition wall are corrugated, the corrugations of both gulls and partitions are horizontal.

На фиг. 1 изображен предлагаемый теплообменник, продольный разрез; 5 на фиг 2 - сечение А-А на фиг. 1; на фиг. 3 - сечение Б-Б на фиг. If на фиг. 4 - узел I на фиг. 1.FIG. 1 shows the proposed heat exchanger, longitudinal section; 5 in FIG. 2 - section A-A in FIG. one; in fig. 3 is a section BB in FIG. If in FIG. 4 — node I in FIG. one.

Теплообменник содержит трубный пучок 1, закрепленный в трубных The heat exchanger contains a tube bundle 1, fixed in the tube

20 решетках 2 и 3 и заключенный в шестигранную обечайку 4, имеющую зазор с кожухом 5, продольную перегородку 6, расположенную внутри трубного пучка 1 и прикрепленную к решет25 кам 2 и 3, и патрубки подвода 7 и отвода 8 теплоносител (парогазовой смеси), размещенные с противоположных сторон кожуха 5, а обечайка 4 расположена между ними и в зоне 20 grids 2 and 3 and enclosed in a hexagon shell 4 having a gap with a casing 5, a longitudinal partition 6 located inside the tube bundle 1 and attached to the grids 25 and 2 and 3, and inlet pipes 7 and outlet 8 of the heat carrier (steam-gas mixture) placed on opposite sides of the casing 5, and the shell 4 is located between them and in the zone

Claims

30 nozzles 7 and 8 have segmented edges 9 and 10, prth / plc to the casing 5. O61 of the end of the partition 6, located outside of the casing 4 are additionally attached to the casing 5 and the edges 9 and 10 of the casing 4. Casing 4 and the b wall are filled corrugated, with corrugations arranged horizontally. The gas-vapor mixture through the pipe 7 enters the annular space of the tube bundle 1, moves upwards, and then, skirting the upper end of the hexagonal shell 4, passes in the gap between the latter and the casing 5 and through the lower end of the shell 4 enters the refrigerating part of the heat exchanger where it moves from the bottom up and out through the side of side 8. The proposed device allows to intensify heat exchange and reduce the metal consumption of the installation. Claim 1. Shell-and-tube heat exchanger containing tube bundle, fixed in tube grids and enclosed hex shell, having a gap with the sleeve, longitudinal partition located inside the tube bundle and attached at one end to one of the tube grids, and inlet and outlet pipes of the heat carrier, different By the fact that, in order to intensify heat exchange and reduce metal consumption, the pipes are placed on opposite sides of the casing, and the shell is located between them and has a segment in the area of the pipes. The vent edges adjoining the casing, with the other end attached to the second tube sheet and both ends located outside the shell, are additionally attached to the shell and the edges of the shell.

2. A heat exchanger according to claim 1, characterized in that the shell and the partition are corrugated.

3. Heat exchanger according to claim 2, characterized in that the corrugations of the shell and the partitions are horizontal. Sources of information taken into account in the examination 1. USSR author's certificate 60688, cl. F 28 F 9/02, 1938.
