Abstract
The utility model discloses a kind of heat-exchanger rigs, including frame, tube sheet, heat exchanger tube, expansion joint, shell, it is characterized by: the heat exchanger tube is vertically located in the tube sheet, the fixed expansion joint, the frame are fixedly arranged on the shell end between the tube sheet and the frame.So set, solving the stress problem between heat exchanger tube expansion issues and tube sheet and frame, the service life and safety of heat-exchanger rig are improved.
Description
Technical field
The utility model relates to a kind of heat-exchanger rigs, belong to mechanical equipment technical field.
Background technique
Heat exchanger is widely used common apparatus in the industries such as many metallurgy, chemical industry, and type is more, wherein pipe heat exchanger
Be it is most common, pipe heat exchanger major advantage be structure it is simple, it is compact, elevated pressures can be born, in pipe heat exchanger, by
It is different in the temperature of the inlet and outlet of two fluids, when the temperature difference of two kinds of fluids is larger, temperature difference pressure can be generated in shell wall and tube wall
Power causes equipment to deform, in addition bending or rupture, generally when the temperature difference be greater than 50 DEG C when be considered as on shell increase expansion joint with
Absorption heat-exchange tube swelling amount eliminates stress, has the function that protect heat exchanger.
The way that previous pipe heat exchanger solves heat exchanger tube swell increment is that the swollen of helicitic texture form is filled on every heat exchanger tube
Swollen section, the disadvantage is that high production cost, the set-up time is long and shell form is relatively simple, and not can solve tube sheet and frame it
Between generated stress problem.
Utility model content
The purpose of this utility model is to provide the heat-exchanger rigs that a kind of service life is high and safety is good.
To achieve the above objectives, the present invention adopts the following technical solutions: a kind of heat-exchanger rig, including frame, tube sheet,
Heat exchanger tube, expansion joint, shell, the heat exchanger tube are vertically located in the tube sheet, fixed institute between the tube sheet and the frame
Expansion joint is stated, the frame is fixedly arranged on the shell end.
As the further improved technical solution of the utility model, the expansion joint cross section is W type.
As the further improved technical solution of the utility model, the expansion joint opening end surface is vertical with frame solid
If the non-opening portion concave part of the expansion joint and tube sheet perpendicular are fixed.
As the further improved technical solution of the utility model, the expansion joint and the tube sheet and the frame are used
Welding manner is fixed.
As the further improved technical solution of the utility model, the shell is round or rectangle.
As the further improved technical solution of the utility model, the expansion joint is manufactured using heat-resisting material.
The utility model has following technical effect that
Using the expansion joint fixed between the tube sheet and the frame, the frame is fixedly arranged on the shell ends
Portion, the expansion joint use W type, solve heat exchanger tube expansion issues, while also solving the stress problem between tube sheet and frame,
And shell form is also possible to rectangle or circle, promotes heat-exchanger rig service life.
The utility model expansion joint is manufactured using high temperature resistant material, can directly be contacted with high-temperature flue gas, and heat exchanger is improved
Versatility.
Detailed description of the invention
Fig. 1 is the utility model embodiment partial front elevation view.
Fig. 2 is the top view of Fig. 1.
Specific embodiment
The utility model is described in detail with embodiment with reference to the accompanying drawing.
It, below will be right in order to illustrate more clearly of specific embodiment of the present invention or technical solution in the prior art
Specific embodiment is briefly described, it should be apparent that, be described below in embodiment be the utility model some implementations
Mode for those of ordinary skill in the art without creative efforts, can also be according to these implementations
Example obtains other embodiments, it should be understood that the words such as " connection ", " installation ", " fixed " described in being described below,
In the case where being not particularly illustrated, it can be and be directly connected to, install, fixing, be also possible to be indirectly connected with, install, fix, that is, permit
Permitted have the intervention of third party's substance.
Referring to shown in Fig. 1 to Fig. 2, the utility model discloses a kind of heat-exchanger rig, including frame 1, expansion joint 2, tube sheet
3, heat exchanger tube 4, shell 5, the heat exchanger tube 4 are vertically located in the tube sheet 3, and fixed multiple heat exchanger tubes 4, described on the tube sheet 3
The fixed expansion joint 2 between tube sheet 3 and the frame 1, the frame 1 is fixedly arranged on 5 end of shell, in order to more preferably solve
Heat exchanger tube expansion issues, while also solving the stress problem between tube sheet 3 and frame 1, which is designed as
W type, 21 end face of expansion joint opening portion of the W type and frame 1 vertical fixed, the non-opening of the expansion joint of the W type by welding manner
It is vertical fixed by welding manner with tube sheet 3 at portion's concave part 22, so as to the modified difference preferably to tube sheet 3 and frame 1 into
Row compensation eliminates between frame 1 and heat exchanger tube 4 thermal (temperature difference) stress because of caused by the temperature difference, significantly improves the problems in stress collection.
Due to using the expansion joint 2 of W type, so that the heat-exchanger rig shell 5 can be using round or rectangle, so as to root
Selection 5 outer shape of shell is adjusted according to working condition requirement.
2 service life of expansion joint of W type in order to better improve, the expansion joint 2 of the W type adopt heat-resisting material manufacture, such as
Stainless steel etc. contacts the expansion joint 2 of the W type directly with high-temperature flue gas, and can mention using the expansion joint 2 of the W type
Rise heat-exchanger rig safety.
The foregoing is merely the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
It is equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, directly or indirectly uses
In other related technical areas, it is also included in the patent protection scope of the utility model.
