The present invention relates to a kind of petal heat exchanger tube and full-circle spray pattern orifice plate combination type heat exchange element, including multiple full-circle spray pattern orifice plates along the parallel longitudinal setting of heat exchanger, and multiple pass perpendicularly through the petal heat exchanger tube that full-circle spray pattern orifice plate is connected with two ends tube sheet;Described petal heat exchanger tube uses that plain tube is integrally formed makes, and its two ends and tube sheet junction are straight length, and middle part is pressed into petal pipeline section, and petal pipeline section is along longitudinally having straight groove or spiral slot;The through hole that on full-circle spray pattern orifice plate, corresponding petal pipeline section passes through is manhole, and its diameter matches with petal pipeline section cross section maximum outside diameter.The present invention utilizes the combination of special shape between heat exchanger tube and orifice plate through hole, is effectively improved the heat exchange efficiency of heat exchanger, reduces the generation of dirt, reduce shell side resistance, solve shell-side fluid skewness, the problem of hull vibration, additionally there is convenient disassembly, reduce the advantages such as equipment, cost are low.

Description

A kind of petal heat exchanger tube and full-circle spray pattern orifice plate combination type heat exchange element
Technical field
The present invention relates to technical field of heat exchangers, particularly relate to a kind of petal heat exchanger tube and change with full-circle spray pattern orifice plate combination type Thermal 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, and reliable operation, is also to use most heat exchanger-type in actual production Type.
Straight tube heat exchanger tube is the parts being most frequently with in shell-and-tube heat exchanger, and tubular form is single, itself and segmental baffle Coordinating cross-flow heat exchange, heat exchange efficiency is the highest, and easily makes deflection plate outer edge area produce bigger flow dead, and dirt deposition is tight Weight, fluid orthogonal is easily generated shell vibrating after clashing into housing, causes shell side pressure loss bigger.
Summary of the invention
The invention provides a kind of petal heat exchanger tube and full-circle spray pattern orifice plate combination type heat exchange element, utilize heat exchanger tube and hole The combination of special shape between plate through hole, is effectively improved the heat exchange efficiency of heat exchanger, reduces the generation of dirt, reduces shell side resistance, Solve shell-side fluid skewness, the problem of hull vibration, additionally there is convenient disassembly, to reduce equipment, cost low etc. excellent Point.
In order to achieve the above object, the present invention realizes by the following technical solutions:
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;Described petal Shape heat exchanger tube uses that plain tube is integrally formed makes, and its two ends and tube sheet junction are straight length, and middle part is pressed into petal pipe Section, petal pipeline section is along longitudinally having straight groove or spiral slot;The through hole that on full-circle spray pattern orifice plate, corresponding petal pipeline section passes through For manhole, its diameter matches with petal pipeline section cross section maximum outside diameter.
The petal number of described petal pipeline section is 4-6.
Compared with prior art, the invention has the beneficial effects as follows:
1) set petal pipeline section in the middle part of heat exchanger tube, by the body corrugated extruding of circumference, tube side fluid turbulent flow can be improved 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 itself and the fixing of tube sheet and support;
3) due to the particularity of shape, can form the slit flowing of complexity in petal heat exchanger tube, tube side fluid is to pipe Wall washes away acutely, makes tube wall not be easily formed dirt, it is achieved automatically to clear up;
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-shaped structure of corresponding heat exchanger tube main body, use full-circle spray pattern orifice plate, it is to avoid fluid directly clashes into housing, fall The vibration of low heat exchanger, removes dead band, reduces shell-side pressure drop, less scaling in shell side;
6) shell-side fluid flows out from the space jet between full-circle spray pattern orifice plate manhole and petal heat exchanger tube, enhances The turbulent flow of fluid, makes fluid distrbution more uniform, is conducive to improving the heat transfer effect of heat exchanger.
Accompanying drawing explanation
Fig. 1 is the partial structurtes schematic diagram of petal heat exchanger tube of the present invention.
Fig. 2 is the schematic cross-section at petal heat exchanger tube of the present invention and full-circle spray pattern orifice plate combination.
In figure: 1. the petal heat exchanger tube of straight length 2. petal pipeline section 3. full-circle spray pattern orifice plate 4. manhole 5.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described further:
As Figure 1-Figure 2, the petal heat exchanger tube of one of the present invention and full-circle spray pattern orifice plate combination type heat exchange element, bag Include multiple full-circle spray pattern orifice plate 3 along the parallel longitudinal setting of heat exchanger, and multiple pass perpendicularly through full-circle spray pattern orifice plate 3 and two ends tube sheet phase Petal heat exchanger tube 5 even;Described petal heat exchanger tube 5 uses that plain tube is integrally formed to be made, its two ends and tube sheet junction For straight length 1, middle part is pressed into petal pipeline section 2, and petal pipeline section 2 is along longitudinally having straight groove or spiral slot;Full-circle spray pattern The through hole that on orifice plate 3, corresponding petal pipeline section 2 passes through is manhole 4, its diameter and petal pipeline section 2 cross section maximum outside diameter Match.
The petal number of described petal pipeline section 2 is 4-6.
A kind of petal heat exchanger tube of the present invention with the operation principle of full-circle spray pattern orifice plate combination type heat exchange element is: heat exchange Pipe uses smooth straight to make petal-shaped, forms circumference wave structure, and body two ends keep straight tube-like, and tube side fluid is at circumference Under the extruding of wave structure, form complicated slit flowing and be rapidly achieved turbulent flow, effectively reduce dirt in pipe, strengthen heat transfer;Shell Cheng Liuti with the form outflow of jet, strengthens the turbulent flow of fluid from the adjacent petal design space of petal type heat exchanger tube, and raising is changed The heat transfer effect of hot device.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, Any those familiar with the art in the technical scope that the invention discloses, according to technical scheme and Inventive concept equivalent or change in addition, all should contain within protection scope of the present invention.
