Abstract
The utility model provides a kind of dual-tubesheet glass-lined heat exchanger, the technical solution is designed using double tubesheet structure, it is attached since respective tube sheet is respectively adopted in tube side and shell side, break traditional tubular heat exchanger tube side and shell side shares the mode of a connection tube sheet, the risk of cross contamination is reduced to greatest extent, leaks hidden danger convenient for discovery in time；Simultaneously because being provided with guide pipe, act on tube side medium sufficiently in enamel heat exchanger tube, it is ensured that produce to user security.In addition, double tubesheet structure, due to using side tube sheet, other side tetrafluoro baffle plate is fixed, safety accident caused by thus phenomenon will not be prevented because the micro flexible manufacture of temperature of charge difference ambassador's heat exchanger tube basis material is at porcelain phenomenon is collapsed.
Description
Technical field
The utility model relates to technical field of heat exchangers, and in particular to a kind of dual-tubesheet glass-lined heat exchanger.
Background technique
Tubular heat exchanger is the heat exchanger that heat exchange action is realized by two kinds of fluid contacts, at present in chemical industry
Using more universal.In the prior art, tubular heat exchanger mostly uses metal material, but works as by heat exchanging fluid with corrosivity
When, due to that can react with metal material, such heat exchanger will be no longer applicable in；Enamel material is in this case
A kind of ideal selection, however, the leakproofness of junction is difficult to protect since the coefficient of expansion difference of enamel and steel is larger
Card.From the point of view of specific, its two sides tube sheet of the enamel pipe heat exchanger of the prior art and heat exchange pipe connecting structure design are unreasonable, hold
Exchanger tubes and tubesheets junction is easily caused to leak；Meanwhile its tube sheet temperature difference of conventional enamel pipe heat exchanger is larger,
Basis material stress variation is inconsistent to cause tube sheet to collapse porcelain phenomenon.It can be seen that current enamel pipe heat exchanger there is
Certain security risk, it is necessary to be improved from structural level.
Summary of the invention
The utility model is intended to the technological deficiency for the prior art, provides a kind of dual-tubesheet enamel tubulation heat exchange
Device, to solve the glass-lined heat exchanger of the prior art, the technology that exchanger tubes and tubesheets junction is easy to happen leakage is asked
Topic.
To realize the above technical purpose, the utility model uses following technical scheme：
Dual-tubesheet glass-lined heat exchanger, including water inlet, EHA end socket, vessel flange, evacuation port, shell ring ward off glass
Glass tube sheet, collet water inlet, cylinder, tetrafluoro baffle plate, heat exchanger tube, THA end socket, drain hole, tetrafluoro pull rod and distance sink tube are put net
Mouthful, the upper end of collet water outlet, collet, trunnion, feed inlet, discharge outlet, diversion pipe, water outlet, carbon steel tube plate, middle cylinder body connects
It is connected to enamel tube sheet, shell ring is connected to enamel tube sheet upper end, and the upper end of shell ring is connected with carbon steel tube plate, and EHA end socket passes through
Vessel flange is connected on carbon steel tube plate, and EHA end socket upper end is provided with water inlet, and the bottom surface of carbon steel tube plate is connected with diversion pipe,
The bottom surface of enamel tube sheet is connected with heat exchanger tube, and the upper end of the diversion pipe is connected to the inside of EHA end socket, the diversion pipe
Lower end extends in heat exchanger tube, and evacuation port, discharge outlet and water outlet are respectively arranged on the side wall of shell ring, is connected on cylinder inboard wall
There are several tetrafluoro baffle plates being intertwined, the plate face of the tetrafluoro baffle plate and the axis perpendicular of cylinder, cylinder bottom
End is connected with THA end socket, and the bottom end of the THA end socket is provided with drain hole, and tetrafluoro pull rod and distance sink tube are located at inner barrel, institute
The one end for stating tetrafluoro pull rod and distance sink tube is connect with the inside of THA end socket, the other end of the tetrafluoro pull rod and distance sink tube with ward off
The inside of glass tube sheet connects, and collet is attached on the outer wall of cylinder, and collet water inlet, collet are respectively arranged on the collet
Water outlet and drain are fixedly connected with trunnion on the side wall of collet, are provided with feed inlet on the side wall of cylinder.
Preferably, drain is located at the lowest point of collet.
Preferably, the axis of tetrafluoro pull rod and distance sink tube and cylinder is parallel to each other.
Preferably, the trunnion at least 3.
Preferably, the position of collet water inlet is higher than collet water outlet.
In above technical scheme, enamel tube sheet, cylinder, heat exchanger tube, THA end socket, drain hole, feed inlet are enamel
Material.
The operating mode of the utility model is as follows：Cooling water is inputted from water inlet, is entered in heat exchanger tube through diversion pipe, is overflowed
Cooling water be temporarily stored in shell ring, until cooling water is arranged from water outlet after all heat exchanger tubes and shell ring are completely filled with cooling water
Out；At the same time, another way cooling water is injected into collet from collet water inlet, is flowed out from collet water outlet.To be filled in heat exchanger tube
After full cooling water, the material that need to be cooled down is inputted into cylinder from feed inlet, guides and flows through tetrafluoro baffle plate, finally arranged from drain hole
Out, cooling is completed.The dual-cooled mode that above technical scheme uses heat exchanger tube mutually to cooperate with collet, increases heat exchange area；
Because the heat exchanger tube of the device is closed at one end, therefore an enamel tube sheet is only needed, workload is reduced when being overhauled, replaced
Heat exchanger tube is relatively simple；In addition, can be an entirety by the THA end socket of lower end and barrel soldering when device diameters are larger, increase
Add jacket head, so that heat transfer effect at its lower end head is further improved, while reducing leakage point.
The technical advantage of the utility model embodies a concentrated reflection of following several respects：1, double tubesheet structure designs, due to tube side and
Shell side is respectively adopted respective tube sheet and is attached, and breaks traditional tubular heat exchanger tube side and shell side shares a connection tube sheet
Mode reduces the risk of cross contamination to greatest extent, hidden danger is leaked convenient for discovery in time, simultaneously because being provided with guiding
Pipe, acts on tube side medium sufficiently in enamel heat exchanger tube, it is ensured that produce to user security.2, double tubesheet structure is due to using
Side tube sheet, other side tetrafluoro baffle plate are fixed, will not be because of the micro flexible manufacture of temperature of charge difference ambassador's heat exchanger tube basis material
At porcelain phenomenon is collapsed, safety accident caused by thus phenomenon is prevented.In conclusion the utility model has more reliable and more stable knot
Structure feature can bear higher temperature and pressure, meanwhile, without dead angle, pollution-free and be readily cleaned in heat exchanger, also there is land occupation
Small, the easy to install, advantages such as treating capacity is big.
