Description
Technical field
The present invention relates to the tubular heat exchanger technology in the New Equipment Engineering, particularly relate to a kind of tubular heat exchanger of the heat-exchange energy-saving device-specific that is used for 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 to use the most a kind of heat exchanger; 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 is as shown in Figure 1, generally is made up of 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 through support plate (perhaps deflection plate) supporting, and its two ends are pierced in the pore of tube sheet; And be connected, thereby guarantee the sealing and the intensity of joint with tube sheet.Through restrain 2 with the combination of the dividing plate of bobbin carriage 4, can heat exchanger tube 1 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. promptly get a tubular heat exchanger through 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 is when being applied to bad working environments, and is very little even if it import and export to take over bore for fear of the leakage of flow process material, is 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.
Thereupon, the research of the better hermetically-sealed construction except welded seal is connected between the end cap of the people end of always being devoted to bobbin carriage and bobbin carriage.
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 practical application.The main problem that exists is:
The first, complex structure.The sealing of thread-locking ring heat exchanger bobbin carriage, the pressure strip that is wherein adopted, sealing plate and bolt all are consumable accessorys; When leaking appears in sealing, need manual work to bolt on and regulate compensation, the operation of band pressure zone temperature makes troublesome poeration dangerous again.
For example, Chinese utility model patent (Granted publication number is: CN 201751794U) disclose by " a kind of thread-locking ring air cooler bobbin carriage " on February 23rd, 2011, its technical scheme comprise " forms by importing and exporting adapter, top board, plug plate, tube sheet, end plate; it is characterized in that adopting the screw-threaded coupling ring structure; on the plug plate, open bigger hole, the inboard gasket seal that adopts, the outside is provided with sealing plate (8) and pressure strip (10); outside the pressure strip (10) is thread-locking ring (6); the outer ring of thread-locking ring (6) manufactures screw thread, is connected with the screw thread of bobbin carriage plug plate (4), is provided with hold-down ring (7) in the thread-locking ring.”
The second, need high-caliber welding.Seal weld like thin-walled Ω ring structure.
For example; (Granted publication number is China's utility model patent: CN201945238U) disclose on August 24th, 2011 by a kind of " air cooler bobbin carriage sealing device "; Its technical scheme comprises: " this device is box-shaped, mainly is made up of cover plate, top board, two end plates, base plate and tube sheet, and described cover plate, top board, base plate and tube sheet are rectangle; two end plates is rectangle or square, between top board, two end plates, base plate and the tube sheet to be weldingly connected; It is characterized in that the sealing device also comprises Europe rice main officer of Tibet ring sealing plate and rectangular Europe rice main officer of Tibet ring seal disc, the outer end is semicircle Europe rice main officer of Tibet ring around Europe rice main officer of Tibet ring sealing plate and the Ou Mi main officer of Tibet ring seal disc; Europe rice main officer of Tibet ring sealing plate is a uniform thickness rectangle ring, and weld with the end of top board, two end plates and base plate mutually the inner around it, and Europe rice main officer of Tibet ring seal disc places on the rice main officer of Tibet ring sealing plate of Europe and welding mutually around rice main officer of Tibet ring tops, the semicircle Europe of both outermost end; Cover plate covers on the rice main officer of Tibet ring seal disc of Europe and through the end of double-screw bolt with top board, two end plates and base plate and is connected.”
The 3rd, structure is huge.Like common big flange-type sealing, flange and end cap are very thick, and not temperature compensated adjusting.
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 of hydrogen is minimum, 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; Problem in conjunction with traditional tubular heat exchanger sealing exists is improved; Research and develop a kind of simple in structure, sealing reliability good, the thermal efficiency is high, simultaneously the novel tubular heat exchanger of energy savings has very far-reaching and significant meaning in field of engineering technology.
