Conventionally, between shell side medium and tube side medium, tube side medium and external environment condition medium, do not occur generally there will not be medium to interpenetrate problem in the situation that of destruction at construction material, sealing between shell side medium and external environment condition medium mainly contains following two kinds of forms at present: (1) designs separately a heat exchanger shell, after housing and finned-tube bundle complete respectively, finned-tube bundle entirety is put into heat exchanger shell.This scheme design and manufacture is comparatively complicated, and materials demand amount is large, and input cost is higher; (2) an end socket containment vessel of design; end socket containment vessel and tube sheet and heat exchanger side plate are welded respectively; make full use of finned tube tube sheet, tube sheet is brought into play simultaneously and supported finned tube tube bank effect and the effect with support heat exchanger weight as a heat exchanger shell part.This conceptual design, manufacture relatively simply, when materials demand amount and worker, greatly reduce, the relative the first scheme of input cost reduces a lot.
At present, the second form reducing design, manufacture, assembling complexity, the aspect of controlling cost has larger potentiality, but the detailed design of associated components still exist can improvements.Original containment vessel design is on the steel plate after bending, to bore some circular holes 8, and as Fig. 1-2, the containment vessel 1 after boring is welded and fixed with tube sheet 5, collector 9, side plate 7 respectively, as Fig. 3.The containment vessel discharge quantity that former design needs is larger, and cutting drilling operation is loaded down with trivial details and labor content is larger, and containment vessel processing clout size is less, and recycling value is little.Simultaneously, because containment vessel in this scheme and some collectors carry out boxing welding, welding space is less, and collector tube wall is generally thinner; for guaranteeing sealing and preventing tube wall burn-through; generally need to adopt argon arc welding to weld, welding process requirement is higher, and welding job amount is large, difficulty is high.
Summary of the invention
The object of the present invention is to provide a kind of assembly method of end socket containment vessel of finned tube exchanger; its containment vessel discharge quantity obviously reduces; containment vessel cutting zone is two rectangular areas; cutting workload is little, difficulty is low; containment vessel processing clout regular shape, size are larger, can value higher.
The technical solution used in the present invention:
A kind of assembly method of end socket containment vessel of finned tube exchanger, it comprises the steps, 1) making of end socket containment vessel, choose steel plate and carry out blanking, steel plate material bending after blanking is formed to half work type structure, it comprises upper and lower side and middle end face, and at middle end face interval and be parallelly provided with multiple rectangular apertures from top to bottom, rectangular aperture runs through whole containment vessel; 2) with heat exchanger assembling; end socket containment vessel top, bottom respectively with Tube-sheet Welding, the welding of intermediate rectangular cutting openings and end socket, both sides and heat exchanger plate-side plate welding; after welding, each parts form enclosed construction, can effectively completely cut off heat exchanger shell pass medium and external environment condition medium.
Above-mentioned rectangular aperture is upper and lower two, and upper and lower two rectangular apertures are arranged symmetrically with along middle end face center line, also can adopt as required different method for arranging, and upper and lower two rectangular apertures weld with heat exchanger two rows end socket respectively.
The technique effect that the present invention obtains:
1, the design of containment vessel uniqueness makes itself and heat exchanger overall package simple, do not need to make separately heat exchanger shell, design, manufacture, assembling complexity are reduced, reduce materials'use amount, while having shortened worker, reduce heat exchanger component quantity, reduced heat exchanger holistic cost and drop into;
2, cutting workload is little, and cutting accuracy is easy to control, the material shape rule cutting down, and size is larger, can be used in addition, has increased materials'use efficiency;
3, after the invention process, containment vessel directly with end socket welding, no longer, with some collectors welding, substantially do not need to consider welding spatial limitation, weld difficulty low, welding job amount is relatively little.
