Description
Technical field
The invention belongs to pipe heat exchanger maintenance of equipment tool fields, and in particular to a kind of pipe heat exchanger tube bank replacement work
Tool and tube bank replacing options.
Background technique
Pipe heat exchanger is countless in chemical industry, device, during long-term operation, part heat exchanger meeting
Leakage, part heat exchanger can be because material pollution cause many reasons such as heat exchange failure to influence production and heat exchanging device is needed to carry out
It is replaced and cleaned.Therefore very high in the frequency of chemical industry more switching heat-exchanger.
Grasp at this stage to pipe heat exchanger replacing options, it is as shown in Figure 1 and Figure 2, straight with jack substantially with regard to two kinds
It connects export and is extracted out with tube bundle extracting machine, and all there is limitation in both methods, it is specific as follows：
It is had the disadvantage that with the method that jack is poured out：
1, it has bad luck unstable, discontinuity to be easy to collide with, replacement quality does not ensure.
2, strength is suppressed due to discontinuity and is easy to cause stuck, so that the construction time is elongated, labor intensity increases cost
It improves.
3, when tube bank will extract out, due to the flexible deformation of suspender belt and chain block etc. itself, under causing tube bank to be self-possessed
It is heavy, it is easy so that tube bank elbow collides with heat exchanger shell pass, so that the construction quality of heat exchanging device brings certain wind
Danger.
The method of tube bundle extracting machine core pulling has the shortcomings that as follows：
1, just have part tube bundle extracting machine currently on the market, to pipe heat exchanger core pulling, but also only limit on construction ground compared with
Wide place, many place tube bundle extracting machines can not be sent to position and cannot achieve the effect that core pulling on device, in addition tube bundle extracting machine
There is also limitations for the size matching of size heat exchanging device.
2, tube bundle extracting machine currently on the market is all non-detachable, needs the mating implementation transport such as crane, wooden handcart, transport at
This is higher, and the tube bundle extracting machine to get off that leaves unused takes up too much space.
In conclusion pipe heat exchanger is badly in need of a kind of replacing tool high-efficient, at low cost when replacing.
Summary of the invention
