Background technology
Shell-and-tube heat exchanger is recovery waste heat, waste liquid, improves the common equipment of heat utilization rate, and heat exchanger tube and deflection plate are then
The core parts of shell-and-tube heat exchanger.Shell-and-tube heat exchanger generally uses straight tube heat exchanger tube and segmental baffle combination as heat exchange unit
Part, it is the highest to there is heat exchange efficiency in the heat exchange element of this form, and in heat exchanger, dirt deposition is fast, the difficult cleaning of dirt, shell side pressure
The problems such as fall is big, and equipment cost is high.
Summary of the invention
This utility model provides a kind of tapered increaser and petal orifice plate combination type heat exchange element, utilizes heat exchanger tube axially to cut
The cyclically-varying in face and the special construction of petal orifice plate, be effectively improved the heat exchange efficiency of heat exchanger, suppresses the generation of dirt,
Reduce shell side resistance；The most also there is convenient disassembly, reduce the advantages such as equipment, cost be low.
In order to achieve the above object, this utility model realizes by the following technical solutions:
A kind of tapered increaser and petal orifice plate combination type heat exchange element, including multiple petal orifice plates be arrangeding in parallel with wear
It is inserted in the heat-exchanging tube bundle on petal orifice plate；Described heat-exchanging tube bundle includes many tapered increasers, tapered increaser vertically by
Contraction section trunnion section diffuser direct current section body periodic arrangement is formed, wherein on direct current section body and petal orifice plate
Through hole coordinates fixing；Through hole internal diameter on petal orifice plate is tangent with direct current section outer tube diameter, and is circumferentially uniformly arranged several
Arc elongated hole is formed petal.
Each section of body of described tapered increaser is formed by straight tube compacting.
The profile of described petal orifice plate adapts with cross sectional shape in heat exchanger shell.
The length of described contraction section is more than the length of diffuser.
Compared with prior art, the beneficial effects of the utility model are:
1) heat exchanger tube body has contraction section-trunnion section-diffuser-periodically variable structure of direct current section vertically, therein
Fluid is under the barometric gradient that direction changes repeatedly flowing all the time, is rapidly achieved turbulent flow, can strengthen under the least flow velocity
Heat-transfer effect；
2) diffuser length is short, makes fluid explosion form whirlpool, destroys flow boundary layer, reduces heat transmission resistance, carry
High heat exchange efficiency, is not easily formed dirt, it is achieved automatically clear up；
3) direct current section can lossless with petal orifice plate coordinate, and reduces the wear rate of heat exchanger tube, simplifies the installation of heat exchanger tube,
More easily dismantle；
4) due to the raising of heat exchange efficiency, making heat exchange area reduce, equipment volume declines therewith so that it is manufacturing cost is significantly
Reduce；
5) petal orifice plate is perforated baffle, can increase unit interval heat exchange amount, reduces shell-side pressure drop, is not likely to produce dirt
And vibration；
6) shell-side fluid is gone out from the crack region jet of petal through hole with tapered increaser, strengthens the less turbulence of fluid,
Improve the coefficient of heat transfer of shell side.

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 it is shown in figure 1, the tapered increaser of one described in the utility model and petal orifice plate combination type heat exchange element, including many
The individual petal orifice plate 1 be arrangeding in parallel and the heat-exchanging tube bundle being interspersed on petal orifice plate 1；Described heat-exchanging tube bundle includes many
Tapered increaser 2, tapered increaser 2 is vertically by the contraction section 5 trunnion section 6 diffuser 7 direct current section 4 body cycle
Arrangement forms (as shown in Figure 2), and wherein direct current section 4 body coordinates fixing with the through hole 3 on petal orifice plate 1；Petal
Through hole 3 internal diameter on shape orifice plate 1 is tangent with direct current section 4 outer tube diameter, and is circumferentially uniformly arranged several arc elongated hole shape
Become petal (as shown in Figure 3).
Each section of body of described tapered increaser 2 is formed by straight tube compacting.
The profile of described petal orifice plate 1 adapts with cross sectional shape in heat exchanger shell.
The length of described contraction section 5 is more than the length of diffuser 7.
It is low that this utility model mainly solves the heat exchange efficiency that shell-and-tube heat exchanger generally exists, and in heat exchanger, dirt deposition is fast, difficult clear
Reason, the problems such as shell-side pressure drop is big, and equipment cost is high, it is proposed that a kind of tapered increaser and petal orifice plate combination type heat exchange unit
Part.
Tapered increaser described in the utility model with the operation principle of petal orifice plate combination type heat exchange element is: in heat exchange element
Heat exchanger tube be tapered increaser 2, use smooth straight be pressed into contraction section 5-trunnion section 6-diffuser 7-direct current section 4,
It is axially formed the cyclically-varying in body cross section.Tube side fluid is gradually lowered at contraction section 5 pressure, and flow velocity raises, and reduces
Fluid boundary layer；Reaching maximum at trunnion section 6 flow velocity, form lower pressure environment, suck more tube side fluid, enhanced heat exchange is imitated
Really；At diffuser 7 fluid explosion, produce violent whirlpool and strengthen heat transfer；Direct current section 4 is used for and petal orifice plate 1
Coordinate and install, the most easy to wear.Deflection plate in heat exchange element is petal orifice plate 1, and orifice surface is offered multiple petal logical
Hole 3, is used for fixing tapered increaser 2, and utilizes the crack region of petal through hole 3 and tapered increaser direct current section 4 to penetrate
Go out fluid, fluid through rough baffling, strengthens the turbulent flow of fluid at tapered increaser 2 outer wall, it is to avoid fluid is straight
Connect shock housing, less scaling, reduce shell-side pressure drop, reduce the vibration of heat exchanger, improve the heat transfer effect of heat exchanger.
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
