Description
Technical field
This utility model is related to technical field of heat exchangers, more particularly to a kind of petal heat exchanger tube is combined with full-circle spray pattern orifice plate
Formula heat exchange element.
Background technology
Shell-and-tube heat exchanger is widely used in the fields such as chemical industry, oil, environmental protection, occupies critical role in the industrial production,
Due to its low cost of manufacture, easy to clean, treating capacity is big, adopts most heat exchanger-types in reliable operation, and actual production
Type.
Straight tube heat exchanger tube is the part being most frequently with shell-and-tube heat exchanger, and tubular form is single, itself and segmental baffle
Coordinate cross-flow heat exchange, heat exchange efficiency is not high, and easily make deflection plate outer edge area produce larger flow dead, dirt deposition is tight
Weight, fluid orthogonal are also easy to produce shell vibrating after clashing into housing, cause shell side pressure loss larger.
The content of the invention
This utility model provides a kind of petal heat exchanger tube and full-circle spray pattern orifice plate combination type heat exchange element, using heat exchanger tube
The combination of special shape between orifice plate through hole, effectively improves the heat exchange efficiency of heat exchanger, reduces the generation of dirt, reduces shell side resistance
Power, solves shell-side fluid skewness, and the problem of hull vibration is additionally low with convenient disassembly, diminution equipment, cost
Advantage.
In order to achieve the above object, this utility model employs the following technical solutions realization：
A kind of petal heat exchanger tube and full-circle spray pattern orifice plate combination type heat exchange element, set along heat exchanger is parallel longitudinal including multiple
The full-circle spray pattern orifice plate put, and multiple pass perpendicularly through the petal heat exchanger tube that full-circle spray pattern orifice plate is connected with two ends tube sheet；The petal
Shape heat exchanger tube is made using plain tube is integrally formed, and its two ends is straight length with tube sheet junction, and middle part is pressed into petal pipe
Section, petal pipeline section have straight groove or spiral slot along longitudinal direction；The through hole that the petal pipeline section of correspondence passes through on full-circle spray pattern orifice plate
For manhole, its diameter is matched with petal pipeline section cross section maximum outside diameter.
The petal number of the petal pipeline section is 4-6.
Compared with prior art, the beneficial effects of the utility model are：
1) petal pipeline section is set in the middle part of heat exchanger tube, by the circumferentially corrugated extruding of body, can improve tube side fluid turbulent flow
Degree, thinning flow boundary layer reduce heat transmission resistance, improve heat exchange efficiency；
2) petal heat exchanger tube two ends are straight length, are conducive to its fixation and support with tube sheet；
3) the slit flowing of complexity due to the particularity of shape, can be formed in petal heat exchanger tube, and tube side fluid is to pipe
Wall washes away acutely, makes tube wall be difficult to form dirt, realizes clearing up automatically；
4) due to the raising of heat exchange efficiency, reduce heat exchange area, equipment volume declines therewith so as to which manufacturing cost is significantly
Reduce；
5) petal-shaped structure of correspondence heat exchanger tube main body, using full-circle spray pattern orifice plate, it is to avoid fluid directly clashes into housing, drops
The vibration of low heat exchanger, removes dead band, reduces shell-side pressure drop, less scaling in shell side；
6) space jet of the shell-side fluid between full-circle spray pattern orifice plate manhole and petal heat exchanger tube flows out, and enhances
The turbulent flow of fluid, makes fluid distrbution more uniform, is conducive to improving the heat transfer effect of heat exchanger.

In figure：1. 2. petal pipeline section of straight length, 3. full-circle spray pattern orifice plate, 4. manhole, 5. petal heat exchanger tube
Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described further：
As Figure 1-Figure 2, a kind of petal heat exchanger tube described in the utility model and full-circle spray pattern orifice plate combination type heat exchange unit
Part, including multiple full-circle spray pattern orifice plates 3 along the parallel longitudinal setting of heat exchanger, and multiple passes perpendicularly through full-circle spray pattern orifice plate 3 and two ends
The petal heat exchanger tube 5 that tube sheet is connected；The petal heat exchanger tube 5 is made using plain tube is integrally formed, its two ends and tube sheet
Junction is straight length 1, and middle part is pressed into petal pipeline section 2, and petal pipeline section 2 has straight groove or spiral slot along longitudinal direction；
The through hole that corresponding petal pipeline section 2 passes through on full-circle spray pattern orifice plate 3 is manhole 4, and its diameter is with 2 cross section of petal pipeline section most
Big external diameter matches.
The petal number of the petal pipeline section 2 is 4-6.
A kind of petal heat exchanger tube described in the utility model with the operation principle of full-circle spray pattern orifice plate combination type heat exchange element is：
Heat exchanger tube makes petal-shaped using smooth straight, forms circumference wave structure, and body two ends keep straight tube-like, tube side fluid to exist
Under the extruding of circumference wave structure, form complicated slit flowing and be rapidly achieved turbulent flow, effectively reduce dirt in pipe, strengthen and pass
Heat；Shell-side fluid is flowed out in the form of jet from the adjacent petal design space of petal type heat exchanger tube, is strengthened the turbulent flow of fluid, is carried
The heat transfer effect of high heat exchanger.
The above, only this utility model preferably specific embodiment, but protection domain of the present utility model is not
Be confined to this, any those familiar with the art in the technical scope that this utility model is disclosed, according to this practicality
