Abstract
The utility model discloses a segmented detachable pull rod of a pipe shell type heat exchanger. The pull rod consists of N segments, N is bigger than or equal to 2, and all segments are connected by threads. The pull rod is in a segmented structure. When the pull rod is assembled, not all reflector plates are pierced once. The utility model has the advantages that the segmented detachable pull rod adopting segmented assembly is easy to install, the labour intensity is reduced, and the work efficiency is improved. The utility model is particularly suitable for large pipe shell type heat exchangers.
Description
Technical field
The utility model relates to the chemical industry equipment field, says further, relates to a kind of shell-and-tube heat exchanger removable pull bar of segmentation.
Background technology
According to the regulation of GB151 " shell-and-tube heat exchanger ", pull bar commonly used has 2 kinds of forms: 1) pull bar distance sink tube structure; 2) pull bar and deflection plate Welding Structure.The pull bar of these two kinds of structures all is a monolithic construction, and to general device diameter little (less than 2600mm), length is not the equipment of oversize (less than 10000mm), and is still operable.
Chinese patent (CN2844831Y, denomination of invention: non-equidistant segmental baffle board heat exchangers) disclose a kind of non-equidistant segmental baffle board heat exchangers, be made up of tube sheet, segmental baffle, pull bar, distance sink tube, heat exchanger tube and housing, tube sheet is positioned at two ends, and pull bar, heat exchanger tube pass deflection plate.Be with distance sink tube on the pull bar, distance sink tube is between adjacent two deflection plates identical with the breach direction between adjacent two deflection plates.A plurality of deflection plates equidistant placement not between two tube sheets.By the different spacing of appropriate design deflection plate, satisfy the needs of condensation (evaporation) device different volumes flow rate.Thereby, improve heat-transfer capability, reduce flow pressure drop, the destruction that can also avoid evaporation process to cause heat-transfer equipment is guaranteed the highly effective and safe operation of equipment.
But (present domestic ultra-large type shell-and-tube heat exchanger diameter has reached 7000mm for large-scale shell-and-tube heat exchanger, the equipment of pipe range 20000mm is also of common occurrence), if still adopt whole pull bar then to exist assembly difficulty big (need once pass through all deflection plates, and segmented sectional block-by-block assembling), problems such as poling is unsuitable, workload is big, centering time length, flexible distortion
Therefore need to propose a kind of novel Tiebar structure, solve the problems referred to above that large heat exchanger exists with pull bar.
The utility model content
For solving problems of the prior art, the utility model provides a kind of shell-and-tube heat exchanger removable pull bar of segmentation.Be applicable to large-scale shell-and-tube heat exchanger, be convenient to assembling, increase work efficiency, and easily realize producing in batches, be easy to transportation in the workshop.
The purpose of this utility model provides a kind of tube side formula heat exchanger removable pull bar of segmentation.
Described pull bar is made up of the N section, N 〉=2, between every section by being threaded;
First section front end of described N section is external screw thread, is connected with the internal thread that is provided with on the heat exchanger tube sheet;
The interlude two ends of described N section are provided with internal thread or external screw thread;
The final stage end of described N section is an external screw thread, and the nut outer with deflection plate is connected.
Joining end to end by screw thread between described pull bar section and the section connects, and forms " integral body " pull bar of Len req.During assembling, connect one section pull bar again behind deflection plate of every assembling, up to all finishing.Be convenient to the assembling of (comprising deflection plate, distance sink tube) of large-scale shell-and-tube heat exchanger tube bundle support like this, thus the assembling of convenient whole tube bank.
Major advantage of the present utility model is:
Pull bar is a segmental structure, and whole deflection plates need not be once passed through in assembling simultaneously, and the segmentation assembling is easy to install, and has reduced labour intensity, has improved operating efficiency, is specially adapted to large-scale shell-and-tube heat exchanger.

The specific embodiment
Below in conjunction with embodiment, further specify the utility model.
Embodiment:
As shown in Figure 1:
A kind of shell-and-tube heat exchanger is with the removable pull bar of segmentation, forms first section pull bar 3, interlude pull bar 5 and back segment pull bar 6 by three sections.First section pull bar 3 head end is provided with external screw thread, is connected with internal thread on the tube sheet 1; The external screw thread of interlude pull bar 5 one ends is connected with the internal thread of the other end of first section pull bar 3, and the internal thread of the other end is connected with an end external screw thread of back segment pull bar 6, and the external screw thread of back segment pull bar end fixes with nut 7.
During assembling, be connected one section pull bar again behind one section distance sink tube 2 of every assembling and the deflection plate 4, up to all finishing.Be convenient to the assembling of large-scale shell-and-tube heat exchanger tube bundle support like this, the assembling of convenient whole tube bank.
