Description
Technical field
The application relates to the tubular heat exchanger technology in the New Equipment Engineering, particularly has the tubular heat exchanger bobbin carriage of the improvement of diaphragm seal structure for a kind of high temperature and high pressure condition lower tube box end 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.
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.
The common structure of tubular heat exchanger of the prior art 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, tube bank 2 is made up of heat exchanger tube 1, support plate (perhaps deflection plate) and tube sheet usually, and heat exchanger tube 1 in a row is by support plate (perhaps deflection plate) supporting, and its two ends are pierced in the pore of tube sheet 5, and be connected with tube sheet, thereby guarantee 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, fully with the outer shell side medium heat exchange of pipe.Above-mentioned tube sheet and shell 3 and bobbin carriage 4 etc. by welding or the forced seal of flange bolt shimming fixedly assembling namely get a tubular heat exchanger.
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 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 even if it import and export to take over bore for fear of the leakage of flow process material, 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 of bigbore tube sheet and its both sides and bobbin carriage cylinder weld, make like this, the end of bobbin carriage 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.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, and bobbin carriage flow process just, the Sealing Technology of bobbin carriage just becomes 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 and bobbin carriage 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 along with the going deep into of application in practice, it is found that also there are some disadvantageous places in these structures itself.The main problem that exists is:
The first, complex structure.The sealing of thread-locking ring heat exchanger bobbin carriage, the pressure strip that wherein adopts, 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 the bobbin carriage end adopts the reliable structure of inverse flange and the sealing of sphere film to alleviate construction weight, because providing, the space that the mounting or dismounting of large-area dividing plate and personnel pass in and out bobbin carriage in the bobbin carriage has difficulties again, and because the existence of ball film, traditional plane clapboard hermetically-sealed construction makes and between 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, just having solved the problem that leaks outside still has the new problem of having drawn interior leakage.
The 4th, structure often ftractures, and is dangerous, difficult in maintenance.
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, divide the bobbin carriage that Cheng Xiaoguo is good, the efficiency of loading and unloading is high, has very far-reaching and significant meaning in field of engineering technology.
