Abstract
The utility model belongs to chemical industry equipment manufacturing technology field, in order to overcome the low heat transfer rate of traditional reboiler, the utility model discloses a kind of spiral torsional curved tube reboilers, including shell, tube sheet, helically twisted heat exchange tube, bundle hoop, pull rod and distance sink tube, support plate, weir plate.The heat exchanger tube of spiral torsional curved tube reboiler uses spiral torsional curved tube, and the section of pipe is ellipse, and flattening degree is identical with pitch, and spiral torsional curved tube is pipe with tube sheet junction, and adjacent heat exchange tubes outer rim keeps helix point contact, and is bound together by bundle banding is tightly tired；Shell uses K-type reducing shell, and so that shell side has enough evaporating spaces, shell side tail portion is equipped with weir plate, to ensure that shell side has enough liquid levels；Flow dead zone is not present in shell side no baffle plate.Pipe, shell-side fluid are moved along pipe wall screw, reinforce turbulent motion, so heat transfer coefficient inside and outside pipe can be significantly improved, largely strengthening heat transfer.
Description
Technical field
The utility model belongs to chemical industry equipment manufacturing technology field, and in particular to being used as petrochemical equipment kettle to a kind of
Formula reboiler.
Background technology
Kettle type reboiler is usually used in Fractionator Bottom, so that a part of material vaporization is returned in tower tower base stream heating, to carry
For the required heat source of tower distillation process.Good device structure form not only enables chemical industry production process stablize progress, and
And reduce investment outlay again, energy consumption is reduced, heat transfer efficiency is improved, is conducive to antiscaling, descaling.How to improve heat exchanger efficiency, augmentation of heat transfer,
Studying the new technology of augmentation of heat transfer becomes the focus of people's growing interest.Currently, the type reboiler uses common heat exchanger tube, it is
Ensure shell to have enough evaporating spaces, shell side shell to be variable-diameter structure, causes equipment volume larger, cost is higher, therefore uses
Augmentation of heat transfer heat exchanger tube is imperative, and heat exchange efficiency needs to further increase.
Invention content
It is a kind of spiral torsional curved tube reboiler, the reboiling to overcome the low heat transfer rate of traditional reboiler, the utility model
Utensil has heat exchange efficiency more higher than common reboiler, to improve heat exchange efficiency.
A kind of spiral torsional curved tube reboiler, including shell, tube sheet, helically twisted heat exchange tube, bundle hoop, pull rod and spacing
Pipe, support plate, weir plate, technical solution adopted by the utility model to solve its technical problems is：Spiral torsional curved tube reboiler
Heat exchanger tube uses spiral torsional curved tube, and the section of pipe is ellipse, and flattening degree is identical with pitch, and spiral torsional curved tube is connect with tube sheet
Place is pipe, and adjacent heat exchange tubes outer rim keeps helix point contact, and is bound together by bundle banding is tightly tired, helically twisted in pipe
Oval-shaped passageway makes fluid generate screw and secondary turbulent flow, and turbulence state aggravation enhances intraductal heat transfer；Shell side spiral
Runner also helically shape, is periodically changed speed and side when fluid moves wherein by centrifugation force effect between twisted tube
To the radial direction to strengthen fluid mixes, and the turbulent extent of itself is enhanced, to make shell-side fluid also be strengthened.By
In fluid spiral trend move, turbulent extent is big, can improve often occur in pipe, shell side greasy dirt attachment heat exchange pipe surface and
Impurity deposition is to unfavorable phenomenon of conducting heat；Shell uses K-type reducing shell, so that shell side has enough evaporating spaces, shell side
Tail portion is equipped with weir plate, to ensure that shell side has enough liquid levels；No baffle plate in shell side, no flow dead zone, can reduce or
The vibration of pipe is avoided, equipment cost is reduced.

Specific implementation mode
Spiral torsional curved tube reboiler is to be changed pipe heat exchanger tube into spiral torsional curved tube based on traditional kettle type reboiler and done
For heat exchange element, no baffle plate in shell side, other structures component is all made of the parts of shell-and-tube heat exchanger.
In Fig. 1, heat exchanger tube uses spiral torsional curved tube (2), and the end of spiral torsional curved tube (2) is pipe, spiral torsional curved tube
When reboiler tube bank assembling, fixed tube sheet is fixed in the end of heat exchanger tube（1）On, row's spiral torsional curved tube (2) is often installed, is rotated
Pipe ensures that adjacent heat exchange tubes outer rim keeps helix point contact, is needed for the rigidity of tube bank, and bundle hoop is furnished in tube bank
（5）, it is ensured that it keeps being in close contact between heat exchanger tube, slideway（8）With support plate（3）It mutually welds, is conducive to the installation and extraction of tube bank,
Support plate（3）It plays a supportive role to tube bank, passes through pull rod and distance sink tube（7）Plate spacing is supported in control.Shell（4）Become using K-type
Diameter shell, so that shell side has enough evaporating spaces, shell side tail portion to be equipped with weir plate（6）, to ensure that shell side has enough liquid levels
Highly.
The utility model is significant to miniaturization, densification, energy saving material saving etc., is that the new and effective heat exchange of one kind is set
It is standby.
