Description
Technical field
The application is related to the Sealing Technology of the tube header of tube-type heat exchanger in New Equipment Engineering, is more particularly to refined for oil
System is changed with a kind of shell and tube of chemical industry, Coal Chemical Industry, chemical fertilizer industry, air-conditioning, air cooling, the heat-exchange energy-saving device-specific of electric power facility
Hot device bobbin carriage barrier film pad.
Background technology
In the prior art, tubular heat exchanger is a kind of heat exchanger being most widely used, and is widely used in chemical industry, stone
In the field such as oil, medicine, food, light industry, metallurgy, coking " liquid --- liquid ", " vapour --- vapour ", " vapour --- liquid " heat exchange
Convection heat transfer' heat-transfer by convection, and the heat exchange condensation flow such as steam condensation and liquid evaporation heat transfer.
The open-ended diaphragm sealing structure of tube header of tube-type heat exchanger of the prior art, as shown in figure 1, typically by managing
The main members such as beam 2, shell 3, bobbin carriage 4 constitute, wherein, tube bank 2 be tubular heat exchanger core components, tube bank 2 generally by
Heat exchanger tube, support plate（Or deflection plate）Constituted with tube sheet 5, rows of heat exchanger tube passes through support plate（Or deflection plate）Supporting,
Its two ends is pierced into the pore of tube sheet 5, and is connected with tube sheet 5, so as to ensure the sealing and intensity of joint.By tube bank 2
With the combination of the dividing plate of bobbin carriage 4, heat exchanger tube can be divided into several flows, so that medium flows back and forth in heat exchanger tube, so that
Can extend heat exchange process, increase heat-exchange time, fully with pipe outside shell side media for heat exchange.Above-mentioned tube sheet 5 and shell 3 and pipe
The grade of case 4 obtains final product a tubular heat exchanger by the forced seal fixing assembling of welding or flange bolt shimming.
When the heat exchange medium in heat exchange tube is cold medium, when the heat exchange medium outside pipe is the flue gas of forced convertion,
Then constitute heating furnace mode；When the heat exchange medium in heat exchange tube is thermal medium, the heat exchange medium outside pipe is forced convertion
Air when, then constitute 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 more ripe, and security performance is also higher, is the energy consumption equipment of key in heat transmission equipment.
Above-mentioned tubular heat exchanger of the prior art when bad working environments are applied to, in order to avoid letting out for flow material
Leakage, even if the bore very little of adapter 10 of its import and export, is usually designed to the mode with the direct butt welding of pipeline, without being connected using flange
The mode for connecing；Equally, in order to avoid the leakage of flow material, the shell 3 and the circle of bobbin carriage 4 of bigbore tube sheet 5 and its both sides
Cylinder is welded, so that, the end 9 of bobbin carriage 4 cannot be also adopted by the weldering of equal strength weld seam and the end cap 7 of bobbin carriage 4 between
The mode for connecing, is mainly in view of and facilitates the maintainer to enter to carry out the first-class repair work of detection pipe from the end 9 of bobbin carriage 4.
Therewith, people are devoted between the end 9 of bobbin carriage 4 and the end cap 7 of bobbin carriage 4 except non-disconnectable strength solder joints always
The research of the better seal structure outside connection.Wherein sphere film sealing 6 is a kind of newest resulting structure.With practice
That applies gos deep into, it has been found that the structure there is also following unfavorable problem in itself：
First, structure is special, and spherical curved face processing required precision is high.
Second, it is necessary to high-caliber argon arc welding, and is the obstacle weldering after fastening stud 8, it is impossible to damage the end of bobbin carriage 4
9 with the end cap 7 of bobbin carriage 4.
3rd, installation accuracy is high.
4th, dismounting inconvenience is, it is necessary to remove seal-weld, side ring belongs to consumable accessory, difficult in maintenance.
To sum up, complicated or huge heat exchanger assembly and disassembly trouble, inconvenient maintenance.Particularly during device overhaul, can contract
A short repair time can produce significant economic benefit.With the enhancing of environmental protection consciousness, the lifting of oil quality is needed
Take the hydrogenation technique under high pressure at higher temperature, the molecule of hydrogen is minimum, be the very strong inflammable and explosive medium of permeability, it is original
Sealing structure is difficult in adapt to new technique and management is required.
Again therewith, the applicant have developed a kind of tube header of tube-type heat exchanger sealing gasket, change by sealing side ring
Enter, further the clamping face using the mat surface having convexly and/or concavely as sealing side ring with the end of bobbin carriage or sealing strip
The clamping face of the end cap of ring and bobbin carriage, breaches this area conventional thought pattern, increased contact action power, with from multi-turn circumference
Direction intercepts leakage and the internal pressure impulsive force in the clamping face between sealing side ring and the end of bobbin carriage, in multi-turn convexly and/or concavely
Mat surface obstruct under so that leakage effects power is reduced to zero, finally to improve the end of bobbin carriage and the end cap of bobbin carriage
Sealing property, meanwhile, from for radial direction, also increase sealing side ring and the friction between the end of bobbin carriage and the end cap of bobbin carriage
Power so that under HTHP effect, it is only deformation-compensated by be carried out by sphere flexible sheet, prevent the radial direction of plain cushion side ring
Displacement, to reduce the risk of leakage；However, above-mentioned sealing gasket cannot be produced from the predeformation and prestressing force for producing and needing, it is impossible to
Preferably adapt to dynamic operation condition.
To sum up, applicant is improved again continuing with the problem that the sealing of traditional tubular heat exchanger is present, research and development one
Improved tube header of tube-type heat exchanger barrier film pad is planted, there is extremely far-reaching and great meaning in field of engineering technology.
The content of the invention
The purpose of the application is to avoid weak point of the prior art and provide a kind of with stronger elastic deformation
Ability, can produce the predeformation and prestressing force that need by adjusting, and be more suitable for dynamic operation condition, and can solve major diameter barrier film weight
The problem of installation difficulty when measuring heavier, while also help barrier film centering bobbin carriage end, with simple structure, it is easily assembled,
Sealing property reliable tube header of tube-type heat exchanger barrier film pad.
The purpose of the application is achieved through the following technical solutions：
There is provided a kind of tube header of tube-type heat exchanger barrier film pad, it is arranged between the end of bobbin carriage and the end cap of bobbin carriage,
The barrier film pad includes the sealing side ring that the elastic diaphragm located at centre and the outer circumferential side along the elastic diaphragm are set, its
In,
The elastic diaphragm is towards being fixedly connected with location adjusting device, the positioning in the middle part of the side of the end cap
Adjusting means wear the end cap and can jacking or stretching to be applied to one predeformation of the elastic diaphragm and prestressing force.
Wherein, the location adjusting device includes locating rod and adjusting nut, and the locating rod wears the end cap and leads to
The effect jacking or stretching of the adjusting nut for coordinating are crossed to be applied to one predeformation of the elastic diaphragm and prestressing force.
Wherein, the elastic diaphragm is individual layer thin-wall construction, or the combination thin-wall construction more than two-layer being superimposed.
Wherein, the elastic diaphragm is planar separator piece or convex surface diaphragm, and the convex surface diaphragm includes the conical surface
