Background technique
Heat-exchanger rig is a kind of heat-exchange apparatus and is widely used in different field, to realize returning for heat or cooling capacity
It receives, realizes energy recycling, reduce cost and environmental pollution.Heat-exchanger rig by two kinds of fluids with the temperature difference of circulation with
Realize the heating of cryogenic media and the cooling of high-temperature medium, (cryogen needs heat, high temperature fluid so that realization is taken what one needs
Need cooling capacity) to realize heat exchange.The stroke usually flowed in heat exchanger tube is tube side, in the stroke that the outside of heat exchanger tube is flowed
For shell side, in order to guarantee the loss of medium, the heat exchanger tube of fixed tube-sheet exchanger must be fixedly mounted with tube sheet, and and tube sheet
The siding set to be formed for flowing another transfer is enclosed jointly to need to be tightly connected with tube sheet；But often because of heat exchanger tube and siding
The temperature difference is larger, causes the thermal expansion amount of heat exchanger tube and siding different, causes the junction of tube sheet and siding easy to damage；Can also simultaneously
Cause the heat exchanger tube for being set to tube sheet damaged due to thermal (temperature difference) stress, also will appear the connection damage of heat exchanger tube and tube sheet；It is above existing
Service life as shortening heat-exchanger rig causes the use cost height of heat-exchanger rig, safety in utilization lower.
In the prior art, the different thermal expansion amount of shell journey usually is solved in expansion joint is arranged on shell side, but for portion
Divide the heat exchanger of rectangular section, common expansion joint structure can not solve the difference heat that siding and heat exchanger tube occur by the temperature difference
Expansion issues, and the structure of compensation waveguide cause shell side is set in shell side or causes structural strength not enough (because of the benefit of expansion joint
It repays intensity of wave and rigidity is poor, and the heat exchanger siding of rectangular section is slab construction, intensity and rigidity are also more common logical
Normal circular cross-section is poor, if expansion joint is arranged on siding by common set-up mode, the unbearable medium pressure of siding
Power, it may appear that moderate finite deformation or damage) or lead to compensate wave without as (in order to guarantee the structural strength of shell side, so that compensation
The deformability of wave is greatly reduced)；Therefore, the thermal expansion how solved between heat-exchanger rig all parts simultaneously is different, protects simultaneously
The structural strength for demonstrate,proving heat-exchanger rig is those skilled in the art's problem urgently to be resolved.
Summary of the invention
The object of the present invention is to provide a kind of expansion joint structure and heat-exchanger rig, it ensure that the structure at setting compensation wave is strong
