Description
Technical field
The application relates to the tubular heat exchanger technology in 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 bobbin carriage end cap the bobbin carriage of hermetically-sealed construction.
Background technology
In prior art, tubular heat exchanger is a kind of heat exchanger being most widely used, be widely used in the convection heat transfer' heat-transfer by convection of " liquid---liquid " in the fields such as chemical industry, oil, medicine, food, light industry, metallurgy, coking, " vapour---vapour ", " vapour---liquid " heat exchange, and the heat exchange condensation flow process such as steam-condensation and liquid evaporation heat transfer.
Tubular heat exchanger of the prior art, common structure as shown in Figure 1, generally formed 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 (or deflection plate) and tube sheet conventionally, heat exchanger tube 1 in a row is by support plate (or deflection plate) supporting, its two ends are pierced in the pore of tube sheet, and are connected with tube sheet, thereby ensure 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 in heat exchanger tube 1, thereby can extend heat exchange process, increase heat-exchange time, fully with pipe outside shell side medium carry out heat exchange.Obtain a tubular heat exchanger by above-mentioned tube sheet and shell 3 and bobbin carriage 4 etc. by the fixing assembling of forced seal of welding or flange bolt shimming.
When the heat exchange medium in heat exchanger tube 1 pipe is cold medium, when flue gas that the heat exchange medium outside pipe is forced convertion, form heating furnace mode; When the heat exchange medium in heat exchanger tube 1 pipe is thermal medium, when air that the heat exchange medium outside pipe is forced convertion, form 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 heat transmission equipment.
Above-mentioned tubular heat exchanger of the prior art, for fear of the leakage of flow process material, even if it is imported and exported, to take over bore very little, be usually designed to and the mode of the direct butt welding of pipeline, and the mode that does not adopt flange to connect; Equally, for fear of the leakage of 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 welding mode, mainly consider and facilitate maintainer can enter to carry out from the end of bobbin carriage 4 the first-class repair work of detector tube.And for the sake of security, generally fluid media (medium) higher pressure and temperature being arranged in to flow process in the pipe of heat exchanger tube 1, namely 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 of bobbin carriage 4 and the end cap of bobbin carriage 4 always.
Although people have done long-term effort in the research of above-mentioned hermetically-sealed construction, have for example formed: traditional forced seal structure such as seal weld flange sealing structure, thread-locking ring hermetically-sealed construction of T-slot metal gasket flange sealing structure, thin-walled Ω ring structure; Also for example formed: the self-tightening sealing structures such as B shape ring, C shape ring, O shape ring, cambridge ring, Cachaly seal, Bridgman sealing.Above-mentioned hermetically-sealed construction because of strengthening effect not enough, particularly, along with the going deep into of application in practice, it is found that these structures itself also exist some disadvantageous places, the main problem existing is:
The first, complex structure.The sealing of thread-locking ring heat exchanger bobbin carriage, the pressure strip, sealing plate and the bolt that wherein adopted is all consumable accessorys; In the time that leaking appears in sealing, need to manually bolt on and regulate compensation, the operation of band pressure zone temperature, makes troublesome poeration dangerous again.
The second, need high-caliber welding.As the seal weld of thin-walled Ω ring structure.
The 3rd, huge structure.As common large 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, provide and have difficulties because the interior large-area dividing plate mounting or dismounting of bobbin carriage 4 and personnel pass in and out the space of bobbin carriage 4 again, and due to the existence of sphere film sealing, traditional plane clapboard hermetically-sealed construction makes, between bobbin carriage end cap and bobbin carriage dividing plate, traditional pressing sealing structure to be set, cause the short-circuit failure between the interior different flow processs of bobbin carriage 4, namely solved the problem that leaks outside but drawn again the new problem of interior leakage.
The 4th, structure often ftractures, dangerous, difficult in maintenance.
Above-mentioned traditional plane clapboard, for example: China Patent No. is 201120203863.0 " for the channel mechanisms of 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); installation dividing plate (2) in described bobbin carriage (1); the upper and lower both sides of bobbin carriage (1) are provided with adapter (3); take over (3) upper flange (4) of settling, in described cylindrical shell (6) and bobbin carriage (1), be provided with non-metallic pad (5)." this dividing plate is a horizontally disposed plane clapboard; and its 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 larger; the rigidity requirement for slab construction is also higher, simultaneously also very inconvenient to its dismounting.
To sum up, the complicated or huge heat exchanger structure manufacturing cycle is long, producing cost is high, assembly and disassembly trouble, inconvenient maintenance.During particularly installing overhaul, can shorten a repair time can produce significant economic benefit.Along with the enhancing of environmental protection consciousness; the lifting of oil quality need to be taked the hydrogenation technique under HTHP more; the molecule minimum of hydrogen, be the inflammable and explosive medium that permeability is very strong; original hermetically-sealed construction is difficult to adapt to new process and management requirement; as can be seen here; the problem existing in conjunction with the novel multitubular heat exchanger of bobbin carriage end sphere film sealing is improved; research and develop a kind of simple in structure, sealing reliability good, the efficiency of loading and unloading is high tube header of tube-type heat exchanger dividing plate, there is very far-reaching and great meaning in field of engineering technology.
