Description
Technical field
The utility model is related to a kind of heat exchanger, and in particular to (PFA is English Perfluoro alkane to a kind of PFA
Abbreviation, i.e. perfluoroalkoxy resin, are the copolymers of a small amount of perfluoro propyl perfluoroalkyl vinyl ether and polytetrafluoroethylene (PTFE).Bond vitrified
Property strengthen, melt viscosity decline, and performance is unchanged compared with polytetrafluoroethylene (PTFE)) tubular heat exchanger.
Background technology
In the heat exchanger that the fields such as chemistry, oil, food, metallurgy use, main operational principle is from heat exchanger by material
Internal heat pipeline circulates, and pipeline external fully carries out heat exchange using heat transferring medium with material in pipeline, to reach heat exchange
Purpose, but often have the very strong material of some oxidisability, corrosivity in heat exchange, it is therefore desirable to manufacture heat exchanger
Material has anti-severe corrosive energy, high temperature resistant, high pressure resistant.Heat exchanger major part in the market is made of metal, and shows
So do not possess very strong corrosion resistance.The easy heap scaliness of heat exchanger tube of tubular heat exchanger in the market, needs cleaning,
It is very inconvenient, and leakage is susceptible at tube sheet, pollute environment.While current most heat exchanger heat transfer inefficiency,
Heat exchanger tube short life.
Utility model content
In order to solve defect present in prior art, the utility model provides a kind of PFA tubular heat exchangers, passes through
The defect of product is solved to the improvement of material and technology.
It is as follows that the utility model solves the technical scheme that its technical problem adopted：
The utility model is related to a kind of PFA tubular heat exchangers, it is characterised in that：Including bobbin carriage, tube sheet, deflection plate, change
The adapter of heat pipe, ear mount, exhaust outlet, vessel flange, end socket, sealing ring, leakage fluid dram, bearing, pull bar, cylinder and shell side, described
Seat on cylinder, is provided with installing hole by welded and installed on bearing, fixed on the ground by nut, the exhaust outlet and leakage fluid dram
It is welded on cylinder, the heat exchanger tube is arranged on to be formed on tube sheet and restrains and in cylinder, and the Tube-sheet Welding is in cylinder
Two ends, are welded with bobbin carriage on the end socket, and are arranged on cylinder both sides by vessel flange, and are screwed, end socket and pipe
Sealing ring is housed, effectively prevention tube sheet is leaked because of corrosion, and the deflection plate inner side installed in cylinder staggeredly is simultaneously between plate
Keep the distance of 20～50cm.The pull bar is used for the installation of deflection plate, and pull bar fixes deflection plate position in vertical direction
Put, reduce because fluid matasomatism causes the scraping between heat exchanger tube and deflection plate, improve heat transfer effect.In leakage fluid dram, exhaust outlet
The shell side adapter is fitted with the entrance of bobbin carriage and exit, the ear mount is welded on outside cylinder.
Further instruction, the bobbin carriage, end socket, cylinder inboard wall are laid with material PFA.
Further instruction, is to improve shell-side fluid flow velocity, and the deflection plate of at least 8 is provided with the cylinder.Baffling
Plate can not only prevent fluid short, increase rate of flow of fluid, also force fluid by the multiple cross-flow in regulation path by tube bank, make turbulent flow
Degree is greatly increased.
Further instruction, when plus vapours or high-velocity fluid flow into shell side when, exchange heat pipe can cause it is very big wash away,
So often shell side adapter is expanded in porch, will shell side adapter do flue, to play a part of to buffer.
Further instruction, heat exchanger tube presses equilateral triangle or square arrangement on tube sheet.Triangular arranged compared with
Compact, extratubal fluid less turbulence is high, and individual heat transfer coefficient is big；Square arrangement is then managed outer easy to clean, it is adaptable to easy fouling
Fluid.
The beneficial effects of the utility model are：Anti-corrosion can be carried out, heat exchange efficiency is improved, it is easy to clean, prevent at tube sheet
Leak, increase the life-span of heat exchanger tube.
Description of the drawings
Fig. 1 is the front section view of embodiment of the present utility model.
In figure, 1 is bobbin carriage, 2 is tube sheet, 3 is deflection plate, 4 is heat exchanger tube, 5 is ear mount, 6 is exhaust outlet, 7 is equipment method
It is blue, 8 be end socket, 9 be sealing ring, 10 be leakage fluid dram, 11 be bearing, 12 be pull bar, 13 be cylinder, 14 be shell side adapter.
Specific embodiment
As illustrated, a kind of PFA tubular heat exchangers, it is characterised in that：Including bobbin carriage 1, tube sheet 2, deflection plate 3, heat exchange
Pipe 4, ear mount 5, exhaust outlet 6, vessel flange 7, end socket 8, sealing ring 9, leakage fluid dram 10, bearing 11, pull bar 12, cylinder 13 and shell side
Adapter 14, the bearing 11 on cylinder 13, on bearing 11 installing hole is provided with by welded and installed, is fixed on ground by nut
On, the exhaust outlet 6 and leakage fluid dram 10 are welded on cylinder 13, and the heat exchanger tube 4 is arranged on to be formed on tube sheet 2 and restrains and install
In cylinder 13, the tube sheet 2 is welded on the two ends of cylinder 13, and bobbin carriage 1 is welded with the end socket 8, and is pacified by vessel flange 7
The both sides of cylinder 13 are mounted in, and are screwed, sealing ring 9 is housed between end socket 8 and tube sheet 2, effectively prevention tube sheet is because of corrosion
Leakage, the deflection plate 3 staggeredly installed in the inner side of cylinder 13 and keep the distance of 20～50cm.The pull bar 12 is used to roll over
The installation of stream plate 3, pull bar 12 fixes the position in vertical direction of deflection plate 3, reduces because fluid matasomatism causes heat exchanger tube 4
With the scraping between deflection plate 3, heat transfer effect is improved.In leakage fluid dram 10, the entrance of exhaust outlet 6 and bobbin carriage 1 and exit all
The shell side adapter 14 is installed, the ear mount 5 is welded on outside cylinder 13.The bobbin carriage 1, end socket 8, the inwall of cylinder 13 lay
There is material PFA.To improve shell-side fluid flow velocity, the deflection plate 3 of at least 8 is installed in the cylinder 13.Deflection plate 3 not only may be used
Prevent fluid short, increase rate of flow of fluid, also force fluid by the multiple cross-flow in regulation path by tube bank, make turbulent extent greatly
Increase.When plus vapours or high-velocity fluid flow into shell side when, exchange heat pipe 4 can cause it is very big wash away, so often shell side is connect
Pipe 14 is expanded in porch, will shell side adapter 14 do flue, with play a part of buffering.Heat exchanger tube 4 is on tube sheet 2
By equilateral triangle or square arrangement.Triangular arranged is compacter, and extratubal fluid less turbulence is high, individual heat transfer coefficient
Greatly；Square arrangement is then managed outer easy to clean, it is adaptable to the fluid of easy fouling.
Above-mentioned embodiment only to illustrate technology design of the present utility model and feature, its object is to allow and be familiar with this skill
