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
It is the core parts of shell-and-tube heat exchanger.Shell-and-tube heat exchanger is generally used as heat exchange member using straight tube heat exchanger tube and segmental baffle combination
Part, it is not high to there is heat exchange efficiency in the heat exchange element of this form, and dirt deposition is fast in heat exchanger, the difficult cleaning of dirt, shell-side pressure drop
Greatly, the problems such as equipment cost is high.
The content of the invention
The invention provides a kind of tapered increaser and petal orifice plate combined type heat exchange element, axially cut using heat exchanger tube
The cyclically-varying in face and the special construction of petal orifice plate, effectively improve the heat exchange efficiency of heat exchanger, suppress the generation of dirt,
Reduce shell side resistance；Also there is convenient disassembly simultaneously, equipment, low cost is reduced.
In order to achieve the above object, the present invention is realized using following technical scheme：
A kind of tapered increaser and petal orifice plate combined type heat exchange element, including multiple petal orifice plates be arrangeding in parallel
With the heat-exchanging tube bundle being interspersed on petal orifice plate；The heat-exchanging tube bundle includes many tapered increasers, and tapered increaser is along axle
Formed to by contraction section-trunnion section-diffuser-direct current section body periodic arrangement, wherein direct current section body and petal orifice plate
On through hole coordinate fix；Through hole internal diameter and direct current section outer tube diameter on petal orifice plate is tangent, and is circumferentially uniformly arranged
Several arc elongated holes form petal.
Each section of body of the tapered increaser is suppressed by straight tube to be formed.
The profile of the petal orifice plate is adapted with heat exchanger shell inner section shape.
The length of the contraction section is more than the length of diffuser.
Compared with prior art, the beneficial effects of the invention are as follows：
1) heat exchanger tube body has contraction section-periodically variable structure of trunnion section-diffuser-direct current section vertically, its
In the barometric gradient that changes repeatedly in direction all the time of fluid under flow, be rapidly achieved turbulent flow under the flow velocity of very little, can be with
Augmentation of heat transfer effect；
2) diffusion segment length is short, makes fluid explosion formation whirlpool, destroys flow boundary layer, reduce heat transmission resistance, carry
High heat exchange efficiency, is difficult to form dirt, realizes automatic cleaning；
3) direct current section can reduce the wear rate of heat exchanger tube, simplify the peace of heat exchanger tube with the lossless cooperation of petal orifice plate
Dress, is more easily dismantled；
4) due to the raising of heat exchange efficiency, reduce heat exchange area, equipment volume declines therewith, make its manufacturing cost significantly
Reduction；
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 and tapered increaser, strengthens the turbulence journey of fluid
Degree, improves the coefficient of heat transfer of shell side.

Embodiment
The embodiment to the present invention is described further below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of tapered increaser of the present invention and petal orifice plate combined type heat exchange element, including it is multiple
The petal orifice plate 1 be arrangeding in parallel and the heat-exchanging tube bundle being interspersed on petal orifice plate 1；The heat-exchanging tube bundle is tapered including many
Increaser 2, tapered increaser 2 is formed by the body periodic arrangement of 5-trunnion of contraction section, 6-diffuser of section, 7-direct current section 4 vertically
(as shown in Figure 2), the wherein body of direct current section 4 coordinate with the through hole 3 on petal orifice plate 1 fixes；Through hole on petal orifice plate 1
3 internal diameters and the outer tube diameter of direct current section 4 are tangent, and are circumferentially uniformly arranged several arc elongated holes and form petal (such as Fig. 3 institutes
Show).
Each section of body of the tapered increaser 2 is suppressed by straight tube to be formed.
The profile of the petal orifice plate 1 is adapted with heat exchanger shell inner section shape.
The length of the contraction section 5 is more than the length of diffuser 7.
Present invention mainly solves the heat exchange efficiency of shell-and-tube heat exchanger generally existing is low, dirt deposition is fast, difficult clear in heat exchanger
Reason, shell-side pressure drop is big, the problems such as equipment cost is high, it is proposed that a kind of tapered increaser exchanges heat first with petal orifice plate combined type
Part.
The operation principle of tapered increaser of the present invention and petal orifice plate combined type heat exchange element is：In heat exchange element
Heat exchanger tube be tapered increaser 2, contraction section 5- trunnions section 6- diffuser 7- direct current sections 4 are pressed into using smooth straight, along axle
To the cyclically-varying for forming body section.Tube side fluid is gradually reduced in the pressure of contraction section 5, flow velocity rise, reduces fluid side
Interlayer；Maximum is reached in trunnion 6 flow velocitys of section, environment under low pressure is formed, sucks more tube side fluids, enhanced heat exchange effect；In diffusion
7 fluid explosions of section, produce violent whirlpool enhancing heat transfer；Direct current section 4, which is used to coordinate with petal orifice plate 1, to be installed, and is difficult
Abrasion.Deflection plate in heat exchange element is petal orifice plate 1, and orifice surface opens up multiple petal through holes 3, tapered for fixing
Increaser 2, and using petal through hole 3 and the crack region eject fluid of tapered increaser direct current section 4, fluid is in tapered flaring
Pipe 2 outer wall passes through rough baffling, strengthens the turbulent flow of fluid, it is to avoid fluid directly hits housing, less scaling, reduces
Shell-side pressure drop, reduces the vibration of heat exchanger, improves the heat transfer effect of heat exchanger.
