Description
Technical field
This utility model relates to a kind of heat-exchanging tube bundle, particularly relates to a kind of self-supporting in coking production in heat-exchange apparatus
Formula ripple straight tube heat-exchanging tube bundle.
Background technology
Traditional heat exchangers generally uses straight tube heat-exchanging tube bundle, there is heat exchange efficiency the highest, and in heat exchanger, dirt deposition is fast, dirt
The problems such as difficult cleaning, need to add expansion joint when the temperature difference is big, equipment cost is high.In recent years, occur in that transversally flute tube, shaped telescopic tube,
The heat-exchanging tube bundle of the form such as spiral grooved tube and corrugated tube, but spiral grooved tube is relative not with transversally flute tube heat-exchanging tube bundle heat transfer efficiency
Height, shaped telescopic tube and bellows heat exchanger bundle processing difficulties, easily wear and tear with deflection plate, need to add pipe box during installation, increase cost.
Summary of the invention
This utility model provides a kind of self-support type ripple straight tube heat-exchanging tube bundle, can be effectively improved the heat exchange efficiency of heat exchanger,
The generation of suppression dirt, solves the wear problem between deflection plate, additionally has convenient disassembly, reduces equipment, cost
The advantage such as low.
In order to achieve the above object, this utility model realizes by the following technical solutions:
A kind of self-support type ripple straight tube heat-exchanging tube bundle, including the many heat exchanger tubes be arrangeding in parallel, every heat exchanger tube is straight by ripple
Pipe and smooth straight form, and the main body of ripple straight tube is that bellows piece adds straight tube section structure, i.e. the waveform in a cycle includes ripple
Peak-straight tube-crest-trough；The two ends of ripple straight tube set smooth straight and are connected for fixing with the tube sheet in heat exchanger, heat exchange
Self-supporting is realized by the linear contact lay of straight length between pipe.
Described ripple straight tube uses light-wall pipe to process, and smooth straight uses thick-walled pipe processing, the external diameter of smooth straight and ripple
Internal diameter at stricture of vagina straight tube trough is equal, and it processes through trimming with ripple straight tube junction, and it is interior straight with ripple to stretch into ripple straight tube
Sealing of tube connects.
Compared with prior art, the beneficial effects of the utility model are:
1) heat exchanger tube is added straight length by bellows piece and forms, and the medium in tube side easily forms vortex, improves that pipe is inside and outside to be situated between
The turbulent extent of matter, destroys flow boundary layer, reduces heat transmission resistance, improves heat exchange efficiency；
2) ripple straight tube tube wall is washed away acutely by tube side medium, the vortex of formation and temperature deformation, makes tube wall not be easily formed dirt
Dirt, it is achieved automatically clear up；
3) heat exchanger tube main body is light-wall pipe, it is easy to processing, reduces thermal resistance；
4) due to the raising of heat exchange efficiency, making heat exchange area reduce, heat transmission equipment volume reduces therewith, makes manufacturing cost big
Width reduces；
5) due to ripple straight tube, there is elasticity, when the temperature difference is bigger, it is not necessary to expansion joint is set；
6) self-supporting is realized by linear contact lay between ripple straight tube heat-exchanging tube bundle, without setting deflection plate in heat transmission equipment shell side, stream
Body flows out at tube bank contact gap, eliminates flow dead in shell side, reduces shell-side pressure drop, reduces the abrasion of heat exchanger tube；
7) due to ripple straight tube bundle self-supporting, without flow dead in shell side, less scaling in heat transmission equipment.

Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further:
As in figure 2 it is shown, a kind of self-support type ripple straight tube heat-exchanging tube bundle described in the utility model, it be arranged in parallel including many
Heat exchanger tube, every heat exchanger tube is made up of (as shown in Figure 1) ripple straight tube 2 and smooth straight 1, the main body of ripple straight tube 2
Add straight tube section structure for bellows piece, i.e. the waveform in a cycle includes crest 21-straightway 22-crest 21-trough 23；
The two ends of ripple straight tube 2 set smooth straight 1 and are connected for fixing with the tube sheet 3 in heat exchanger, pass through straight tube between heat exchanger tube
The linear contact lay of section realizes self-supporting.
Described ripple straight tube 2 uses light-wall pipe to process, and smooth straight 1 uses thick-walled pipe to process, outside smooth straight 1
Footpath is equal with the internal diameter at ripple straight tube 2 trough, and it processes through trimming with ripple straight tube 2 junction, and stretches into ripple straight tube
It is welded to connect with ripple straight tube 2 in 2.
Ripple straight tube 2 use light-wall pipe swaging become the bellows piece that is made up of crest, trough and by straightway waveform form straight
Pipeline section, is a kind of special heat exchange tube structure with periodic waveform.Heat exchanger tube two ends are provided with the smooth straight 1 of heavy wall, use
Support between tube sheet 3 is fixed, and utilizes the linear contact lay of straight length to realize the self-supporting between each heat exchanger tube of heat-exchanging tube bundle 6,
Constitute shell side turbulent element.
The operation principle of self-support type ripple straight tube heat-exchanging tube bundle described in the utility model is: tube side fluid is at crest and trough
In behavior of cross section, produce the most radially flow velocity, form eddy-currents, under the least flow velocity, be rapidly achieved turbulent flow,
Strengthen heat transfer, automatically clear up dirt.Straight length realizes self-supporting by linear contact lay, constitutes shell side turbulent element, shell-side fluid
Flow out at tube bank contact gap, increase the turbulivity of fluid, destroy the fluid boundary layer on tube wall, it is to avoid fluid is straight
Connect shock housing, reduce the vibration of heat exchanger, improve the heat transfer effect of heat exchanger.
As it is shown on figure 3, be the partial structurtes signal of self-support type ripple straight tube heat-exchanging tube bundle application state described in the utility model
Figure.Shell-side fluid enters from shell side material inlet, through expanding cylinder 5 and the anti-washing structure of heat exchanger shell 4 composition, carries
High heat exchange area utilization rate.Fluid, in the trough section horizontal mobility of self-supporting ripple straight tube heat-exchanging tube bundle 6, connects from each heat exchanger tube
Touch and flow out at gap, after tube side fluid heat transfer in ripple straight tube 2, leave from shell side material outlet.Tube side fluid is from tube side
Material inlet enters, and after carrying out high efficient heat exchanging with eddy-currents, goes out from tube side material in self-supporting ripple straight tube heat-exchanging tube bundle 6
Mouth leaves.
The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model does not limit to
In this, any those familiar with the art is in the technical scope that this utility model discloses, according to this utility model
Technical scheme and utility model conceive equivalent or change in addition, all should contain protection domain of the present utility model it
