Description
Technical field
The utility model belongs to chemical industry air cooling technique field, especially a kind of single tube double tubesheet air cooler.
Background technology
Air cooler is widely used in chemical industry.There are some poisonous or inflammable, explosive medium, can generally also use air cooling
Device is cooled down.Currently used air cooler is the structure type using single tube plate, when the expansion joint of exchanger tubes and tubesheets loses
After effect, medium will leak at expansion joint in pipe.Inflammable and explosive medium is likely to cause fire or blast.It is and poisonous
Medium can cause field personnel to be poisoned, crisis life security.
Utility model content
To solve to use the structure type of single tube plate existing for prior art, when the expansion joint of exchanger tubes and tubesheets fails
Afterwards, the defects of medium will leak at expansion joint in pipe, the utility model provide a kind of single tube double tubesheet air cooler.
To achieve the above object, the utility model uses following technical proposals：
A kind of single tube double tubesheet air cooler, the air cooler include framework, bellows, heat exchanger tube, curb girder and blower fan, set on framework
There are bellows and curb girder, the air inlet of bellows is disposed with blower fan, and the top of bellows is provided with heat exchanger tube, and the air cooler also includes front tube
Case, front tube sheet, preceding cavity plate, rear cavity plate, back tube sheet and rear header, the front end of heat exchanger tube are connected with front tube sheet and preceding cavity plate, heat exchange
The rear end of pipe is connected with back tube sheet and rear cavity plate, and front header and rear header are respectively welded on front tube sheet and back tube sheet；
Front tube sheet is connected with preceding cavity plate, and a cavity is formed between front tube sheet and preceding cavity plate；
Back tube sheet is connected with rear cavity plate, and a cavity is formd between back tube sheet and rear cavity plate.
Using above-mentioned technical proposal, the purpose for setting forward and backward cavity plate is closed in order to form one with forward and backward tube sheet respectively
Cavity, will not be flowed directly to after dielectric leakage after the jointing of heat exchanger tube and forward and backward tube sheet fails, in heat exchanger tube around
In environment, but stored in the cavity that can be flowed between front tube sheet and preceding cavity plate and back tube sheet and rear cavity plate, so as to anti-
Only in heat exchanger tube dielectric leakage into surrounding environment.
Further, the front end of heat exchanger tube is connected with front tube sheet and preceding cavity plate in the form of expanded joint；The rear end of heat exchanger tube
It is connected with back tube sheet and rear cavity plate in the form of expanded joint.
Using above-mentioned technical proposal, concise production process is made using expanded joint, facilitates operation；Heat exchanger tube can be reduced
Stress effect, improve the quality of junction.
Further, it is bolted between front tube sheet and preceding cavity plate, and passes through gasket seal；Back tube sheet and rear cavity plate
Between be bolted, and pass through gasket seal.
Beneficial effect：
The utility model can be prevented because exchanger tubes and tubesheets jointing fails, and cause in heat exchanger tube dielectric leakage to all
In surrounding environment.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is the enlarged drawing at A in Fig. 1.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.

4 and preceding cavity plate 5 linked together by expanded joint, the rear end of heat exchanger tube 6 is connected to one with back tube sheet 8 and rear cavity plate 7 by expanded joint
Rise, front header 3 and rear header 9 are respectively welded on front tube sheet 4 and back tube sheet 8；
It is bolted between front tube sheet 4 and preceding cavity plate 5, by gasket seal, and between front tube sheet 4 and preceding cavity plate 5
Form a cavity；
It is bolted between back tube sheet 8 and rear cavity plate 7, by gasket seal, and between back tube sheet 8 and rear cavity plate 7
Form a cavity.
A kind of single tube double tubesheet air cooler of the utility model, preceding cavity plate 5 and rear cavity plate 7 respectively with front tube sheet 4 and back tube sheet 8
A closed cavity is formed, after the expansion joint of heat exchanger tube 6 and front tube sheet 4, back tube sheet 8 fails, medium is let out in heat exchanger tube 6
It will not flow directly in surrounding environment, but can be flowed between front tube sheet 4 and preceding cavity plate 5 and back tube sheet 8 and rear cavity plate 7 after leakage
Cavity in store, so as to prevent that dielectric leakage is into surrounding environment in heat exchanger tube 6.
Limitation to scope of protection of the utility model, one of ordinary skill in the art should be understood that in skill of the present utility model
On the basis of art scheme, those skilled in the art need not pay the various modifications that creative work can make or deformation still exists
Within the scope of protection of the utility model.
