FIELD: power engineering. ^ SUBSTANCE: shell-and-tube heat exchanger comprises joined identical sections, every of which comprises a bundle of tubes fixed in tube plates, installed in a vessel, collector chambers of tube and shell media, at the same time each section is equipped with end rigid hollow covers, in the side walls of which perpendicularly to the longitudinal axis of the section there are through holes arranged, at the same time the sections are connected to each other along axes of the provided holes in covers via sealing elements between side walls of covers, cavities of which form a collector chamber of tube medium. Each section is additionally equipped with at least one rigid shell tightly covering the vessel and installed in a gap between end covers, in areas adjacent to tube plates, in side walls of which jointly with the vessel there are through holes arranged, the axis of which lies in the same plane with axes of holes of end covers, at the same time the sections are additionally connected to each other along axes of arranged holes in the shell and the vessel via the specified sealing elements between side walls of the shell, cavities of which form a collector chamber of shell medium. ^ EFFECT: unification and reduction of heat exchanger dimensions. ^ 4 cl, 3 dwg |
