Description
Technical field
The application relates to the tubular heat exchanger technology in the New Equipment Engineering, be applicable to a kind of tubular heat exchanger of the heat-exchange energy-saving device-specific of petroleum refining and chemical industry, Coal Chemical Industry, chemical fertilizer industry, air-conditioning, air cooling, electric power facility, be specially adapted to adopt between the end of high temperature and high pressure condition lower tube box pipe nipple and the bobbin carriage end cap bobbin carriage of hermetically-sealed construction.
Background technology
In the prior art, tubular heat exchanger is a kind of heat exchanger that is most widely used, be widely used in " liquid---liquid ", " vapour---vapour " in the fields such as chemical industry, oil, medicine, food, light industry, metallurgy, coking, the convection heat transfer' heat-transfer by convection of " vapour---liquid " heat exchange, and heat exchange condensation flow processs such as steam condensation and liquid evaporation heat transfer.
Tubular heat exchanger of the prior art, common structure as shown in Figure 1, generally form by main members such as tube bank 2, shell 3, bobbin carriages 4, wherein, tube bank 2 is core components of tubular heat exchanger, and tube bank 2 is made up of heat exchanger tube 1, support plate (perhaps deflection plate) and tube sheet usually, heat exchanger tube 1 in a row is by support plate (perhaps deflection plate) supporting, its two ends are pierced in the pore of tube sheet, and are connected with tube sheet, thereby guarantee the sealing and the intensity of joint.By restrain 2 with the combination of the dividing plate of bobbin carriage 4 etc., heat exchanger tube 1 can be divided into several flow processs so that medium flows back and forth, thereby can prolong heat exchange process in heat exchanger tube 1, increase heat-exchange time, carry out heat exchange with the outer shell side medium of pipe fully.Promptly get a tubular heat exchanger by above-mentioned tube sheet and shell 3 and bobbin carriage 4 etc. by the fixing assembling of the forced seal of welding or flange bolt shimming.
Heat exchange medium in heat exchanger tube 1 pipe is cold medium, when the outer heat exchange medium of pipe is the flue gas of forced convertion, then constitutes the heating furnace mode; Heat exchange medium in heat exchanger tube 1 pipe is a thermal medium, when the outer heat exchange medium of pipe is the air of forced convertion, then constitutes the cooler mode; Heating furnace mode and cooler mode are a kind of heat exchange method of heat exchanger.The manufacturing process of this tubular heat exchanger is comparatively ripe, and security performance is also higher, is energy consumption equipment crucial in the heat transmission equipment.
Above-mentioned tubular heat exchanger of the prior art, very little for fear of the leakage of flow process material even if it import and export to take over bore, be usually designed to the mode with the direct butt welding of pipeline, and do not adopt the flange ways of connecting; Equally, leakage for fear of the flow process material, the shell 3 of bigbore tube sheet and its both sides and the cylinder of bobbin carriage 4 weld, make like this, the end of bobbin carriage 4 just can not and end cap between also adopt the mode of welding, mainly consider to make things convenient for the maintainer can enter to carry out the first-class repair work of detector tube from the end of bobbin carriage 4.And for the sake of security, generally the higher fluid media (medium) of pressure and temperature is arranged in flow process in the pipe of heat exchanger tube 1, just bobbin carriage 4 flow processs make the Sealing Technology of bobbin carriage 4 just become the key of whole heat exchanger.
Thereupon, people are devoted to the research of the better hermetically-sealed construction except non-disconnectable intensity is welded to connect between the end cap of the end of bobbin carriage 4 and bobbin carriage 4 always.
Though people have done long-term effort in the research of above-mentioned hermetically-sealed construction, for example formed: traditional forced seal structures such as the seal weld flange seal structure of T-slot metal gasket flange seal structure, thin-walled Ω ring structure, thread-locking ring hermetically-sealed constructions; For example also formed: self-tightening sealing structures such as B shape ring, C shape ring, O shape ring, cambridge ring, Caza sealing, Bridgman sealing.Above-mentioned hermetically-sealed construction because of strengthening effect not enough, particularly, it is found that also there are some disadvantageous places in these structures itself along with the going deep into of application in practice, the main problem that exists is:
The first, complex structure.The sealing of thread-locking ring heat exchanger bobbin carriage, wherein the pressure strip that is adopted, sealing plate and bolt all are consumable accessorys; When leaking appears in sealing, need manually bolt on and regulate compensation, the operation of band pressure zone temperature makes troublesome poeration dangerous again.
The second, need high-caliber welding.Seal weld as thin-walled Ω ring structure.
The 3rd, structure is huge.As common big flange-type sealing, flange and end cap are very thick, and not temperature compensated adjusting.
If bobbin carriage 4 ends adopt the reliable structure of inverse flange and the sealing of sphere film to alleviate construction weight, because providing, the space that large-area dividing plates mounting or dismounting and personnel pass in and out bobbin carriage 4 in the bobbin carriage 4 has difficulties again, and because the existence of sphere film sealing, traditional plane clapboard hermetically-sealed construction makes and between bobbin carriage end cap and the bobbin carriage dividing plate traditional hermetically-sealed construction that compresses can not be set, cause the inefficacy of the short circuit between the different flow processs in the bobbin carriage 4, just solved the new problem that the problem that leaks outside has still been drawn interior leakage again.
The 4th, structure often ftractures, and is dangerous, difficult in maintenance.
Above-mentioned traditional plane clapboard, for example: China Patent No. is 201120203863.0 " the bobbin carriage mechanisms that are used for heat exchanger ", it discloses and " has comprised bobbin carriage (1), dividing plate (2), takes over (3), flange (4), non-metallic pad (5) and cylindrical shell (6); the interior dividing plate (2) of installing of described bobbin carriage (1); bobbin carriage (1) both sides up and down is provided with adapter (3); take over (3) and upward settle flange (4), be provided with non-metallic pad (5) in described cylindrical shell (6) and the bobbin carriage (1)." this dividing plate is a horizontally disposed plane clapboard; and the one end is connected with tube sheet; and its other end is connected with the end socket of bobbin carriage head; the length of this dividing plate equals the length of bobbin carriage; its area that bears pressure is bigger; the rigidity requirement for slab construction is also higher, and is also very inconvenient to its dismounting simultaneously.
To sum up, the complicated or huge heat exchanger structure manufacturing cycle is long, producing cost is high, assembly and disassembly trouble, inconvenient maintenance.Particularly install during the overhaul, can shorten a repair time can both produce remarkable economic efficiency.Enhancing along with environmental protection consciousness; the lifting of oil quality need be taked the hydrogenation technique under the HTHP more; the molecule minimum of hydrogen, be the very strong inflammable and explosive medium of permeability; original hermetically-sealed construction is difficult to adapt to new technology and management expectancy; this shows; the problem that the novel tubular heat exchanger that seals in conjunction with bobbin carriage end sphere film exists is improved; research and develop a kind of simple in structure, sealing reliability good, the efficiency of loading and unloading is high tubular heat exchanger bobbin carriage dividing plate, have very far-reaching and significant meaning in field of engineering technology.
