Description
Technical field:
The present invention relates to a kind of dish tubesheet heat exchanger of flexible connection ring, be widely used in two kinds of fluid media (medium) dividing wall type exchange heat occasions in the fields such as oil, chemical industry, power, aviation, machinery.
Background technology:
The heat exchanger product is widely used in fields such as oil, chemical industry, power, aviation, machinery, wherein accounts for the ratio nearly 60% of chemical plant facility cost.Mainly be used in two media dividing wall type exchange heat occasion.At present; Heat exchanger form kind is a lot of both at home and abroad; Mainly contain fixed tube-sheet exchanger, movable tube sheets heat exchanger, U type pipe heat exchanger, plate type heat exchanger and spiral-plate heat exchanger, but in actual use, be not that every kind of pattern heat exchange equipment can both be used in various occasions; But use process conditions according to equipment, select suitable heat exchange equipment for use.But the equipment industry is fast-developing along with making; Chemical industry equipment demands such as large-scale oil refining apparatus, large-scale ethylene plant; Many fixed tubular sheet heat exchanger equipment can not satisfy existing manufacturing technique requirent at present, and existing equipment causes equipment manufacturing cost high simultaneously, and the manufacturing cycle is long etc.
Existing fixed formula tubular sheet heat exchanger structure is as shown in Figure 1:
Heat transmission equipment is divided into tube side bobbin carriage and shell-side cylinder 2; The two ends of shell-side cylinder 2 are connected with tube side channel flange 1 through tube sheet 3 respectively; Be provided with many heat exchanger tubes 4 in the shell-side cylinder 2; The two ends of each heat exchanger tube are passed tube sheet and are communicated with and are not communicated with shell-side cylinder with the tube side bobbin carriage, and in shell-side cylinder, are provided with polylith deflection plate 5, and the polylith deflection plate becomes to be crisscross arranged on the flow direction of medium; The typical stream of two kinds of heat transferring mediums is to being: a kind of medium flows into after the heat exchanger tube heat exchange from the A mouth of tube side bobbin carriage, from the B mouth outflow of tube side bobbin carriage; Another kind of medium carries out flowing out from the C mouth after the heat exchange from the D mouth inflow of shell-side cylinder 2 and the medium the heat exchanger tube.Existing equipment in actual use, the following problem that exists in some occasions:
1, on the one hand, because the heat exchange equipment majority all belongs to the pressure vessel category, equipment bearing pressure and device diameters etc. are the important factor of the fixed tube plate thickness of decision.In the maximization heat exchange equipment; Fixed tubular sheet heat exchanger tube plate thickness increases with pressure and diameter; Along with tube plate thickness increases, and the actual heat exchange area of heat exchanger is relevant with the heat exchanger tube effective length, and the heat exchanger tube of tube sheet inside can't heat exchange; Cause the heat exchange area of heat transmission equipment to reduce, influence the heat exchange effect;
2, heat transmission equipment is divided into tube side and shell side usually.Tube side medium fluid and shell side medium fluid are carried out the partition heat exchange through heat exchanger tube.And there is temperature difference in the two media temperature, and when tube side and the shell-side fluid medium temperature difference reached certain numerical value, the shell-side cylinder of heat exchange equipment need be provided with expansion joint 6, and the releasing tube shell side avoids equipment to be destroyed because of the thermal (temperature difference) stress that the temperature difference causes.But along with device diameters becomes big, the expansion joint manufacturing cost strengthens, and the manufacturing cycle is long.Expansion joint bears rigidity load simultaneously has restriction, can't satisfy operating mode needs etc.
Summary of the invention:
For overcoming the defective of prior art; The object of the present invention is to provide a kind of dish tubesheet heat exchanger of flexible connection ring; But the dish tubesheet of employing bearing strain is thin more a lot of than existing tube plate thickness, can make the reduction of equipment materials amount, the drilling of tubesheet processing capacity reduces and manufacturing schedule shortens.
Technical solution problem of the present invention adopts following technical scheme:
The dish tubesheet heat exchanger of flexible connection ring; Comprise shell-side cylinder, be located at the tube side cylindrical shell at said shell-side cylinder two ends; The inner chamber of said shell-side cylinder is provided with many heat exchanger tubes vertically; The two ends of each said heat exchanger tube communicate and do not communicate with the inner chamber of said shell-side cylinder with the inner chamber of said tube side cylindrical shell, have been provided with the flow-disturbing effect and have supported the deflection plate of said heat exchanger tube at the inner chamber of said shell-side cylinder, and the dish tubesheet that is in said shell-side cylinder two ends is set; And be provided with can strain flexible connection ring, said flexible connection ring is tightly connected with the end of said shell-side cylinder, dish tubesheet and said tube side cylindrical shell respectively.
The axial section of said flexible connection ring is " y " font, and promptly a side end face of said flexible connection ring is a monocycle, and the opposite side end face is a dicyclo, and a side end face of monocycle and the end of said shell-side cylinder are tightly connected; One side end face of dicyclo is tightly connected with said dish tubesheet and said tube side cylindrical shell respectively.
Compared with present technology, beneficial effect of the present invention is embodied in:
1, heat exchange equipment of the present invention and existing fixed tube-sheet heat exchanger comparatively speaking, dish tubesheet of the present invention is thinner than existing tube plate thickness, equipment is low with quantity of material, the drilling of tubesheet processing capacity is little and manufacturing schedule is short;
2, the present invention is having under the thermal (temperature difference) stress operating mode through flexible connection ring and dish tubesheet combination, can alleviate release tube side and shell side because of the thermal (temperature difference) stress that the temperature difference causes, avoids the use of the requirement of expansion joint.Particularly be directed against under major diameter and the gravitational load condition, to the demanding situation of equipment rigidity, the axial displacement that produces because expansion joint generally solves thermal (temperature difference) stress etc., but be difficult to solve rigidity requirement;
3, the existing fixed tube-sheet exchanger that has expansion joint, the expansion joint manufacturing cost is high, and the process-cycle is long, and service life is short, and the present invention discharges the thermal (temperature difference) stress of tube side and shell side through flexible connection ring and the combination of dish-shaped thin tubesheet, need not to be provided with expansion joint.
