In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " connection " should be done
It broadly understood, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can be directly connected,
It can also be indirectly connected through an intermediary.For the ordinary skill in the art, can be understood with concrete condition above-mentioned
The concrete meaning of term in the present invention.
As shown in Figure 1, a kind of shell-and-tube heat exchanger reliability demonstration system provided in an embodiment of the present invention, including outer circulation
Access, the both ends of the external circulation path pass through hose respectively and enter with the shell-side outlet 15 and shell side for being verified shell-and-tube heat exchanger 1
Mouth 16 is connected to, and is combined into a closed-loop path；External circulation path is equipped with beam unit, the pump housing 2, thermostat unit, flow
Adjust unit and drain unit, wherein beam unit is used to inject to external circulation path and being verified in shell-and-tube heat exchanger 1
Shell-side fluid；The pump housing 2 is accessed in external circulation path by hose, for circulating shell-side fluid in closed-loop path；
Thermostat unit is used to control the temperature of shell-side fluid；Flow regulating unit is for controlling shell-side fluid in circulating
Flow；Drain unit is arranged between the pump housing 2 and shell side inlet 16, for external circulation path and will be verified shell-and-tube heat exchanger
Shell-side fluid discharge in 1.
Based on above structure, this system analog goes out the shell side cyclic process of shell-and-tube heat exchanger to be verified, in which: folk prescription
Face by thermostat unit by the temperature of shell-side fluid improve to a certain extent, it can be achieved that the heat resistance of baffle plate into
Row verifying；It is one-side to be improved the uninterrupted of shell-side fluid to a certain extent, it can be achieved that doubling by flow regulating unit
The impact resistance of flowing plate can be carried out verifying；On the basis of improving shell-side fluid flow by flow regulating unit, can also it pass through
The cooperation of beam unit and drain unit will be injected into shell side circulation doped with the shell-side fluid of impurity, make containing impurity
Shell-side fluid forms high speed to baffle plate and tube bank and washes away, and thus tests the flushing resistance of baffle plate and tube bank, wherein impurity
It can be by 1000g/m3Fine sand and 500g/m3Iron filings composition deploy.
Moreover, above-mentioned function is had the embodiment of the invention also provides a kind of shell-and-tube heat exchanger reliability verification method
Machine is combined together, and to realize that the reliability to shell-side fluid to be verified forms a systematic judgement, this method is specific
The following steps are included:
S1, shell-side fluid is injected to being verified in shell-and-tube heat exchanger 1；Enable shell-side fluid with set temperature cycle of states stream
It is verified shell-and-tube heat exchanger 1, is discharged it after shell-side fluid recycles setting duration, judges whether to meet baffle plate simultaneously
Do not occur softening and restraining and can not swing in perforation, if so then execute step S2, thens follow the steps S4 if not.
The purpose of step S1 is verified for the heat resistance of baffle plate, because the heat resistance of baffle plate is strong and weak and shell
The reliability of formula heat exchanger is closely related: if there is the phenomenon softened, perforation degrees of expansion is larger after heated in baffle plate,
Then illustrate that it has substantially lost the fixed function to tube bank, that is to say, that if this phenomenon occurs in practical application
In, the stress as caused by shell-side fluid impact baffle plate can be directly delivered to the junction of tube bank and shell, by long-term
The phenomenon that using just easily causing the junction to snap, leak；And this step is only to form target to the heat resistance of baffle plate
To verifying, therefore reliable answer can be obtained to the heat resistance of baffle plate.
S2, Xiang Suoshu, which are verified in shell-and-tube heat exchanger 1, injects shell-side fluid；Shell-side fluid is enabled to be higher than nominal operation pressure
The cycle of states of power, which flows through, is verified shell-and-tube heat exchanger 1, discharges it, judges whether after shell-side fluid recycles setting duration
Meet simultaneously: shell-side fluid pressure in cyclic process does not decline, baffle plate does not deform, restrains and can not swing in perforation
And interbank nothing contacts with each other, and if so then execute step S3, thens follow the steps S4 if not.
The purpose of step S2 is verified to the impact resistance of baffle plate, since the effect of baffle plate is change shell side
The flow direction of fluid, therefore will receive very big impact force, and during this step card, the impact force that baffle plate is subject to mutually compared to
The pressure being subject in real work is also big, and preferably shell-side fluid is flowed into and flowed with the cycle of states of twice of rated operating pressure
It is verified shell-and-tube heat exchanger 1 out.Therefore, if the shock resistance of baffle plate is really insufficient, the result tested should
Be destructive: the degree of baffle plate compressive deformation, which sufficiently achieves, swings tube bank in perforation, so that respectively phase between tube bank inside
Mutual contact wear, and gap may also occur in the bearing of tube bank and shell, any of the above phenomenon occurs, all can directly sentence
It is fixed unreliable.
And if the degree of wear of tube bank and the crack of junction are difficult to discover, it can also be according to shell-side fluid in experiment
Whether pressure reduces as judgment basis in the process, because even occur slight abrasion rupture in tube bank, or tube bank is consolidated
There is small crack in fixed place, then shell-side fluid can all penetrate under a large pressure in tube bank or the bearing by restraining seeps
Out, then the pressure of shell-side fluid will decline, and can specifically be respectively arranged in place of shell side inlet 16 and shell-side outlet 15
First pressure gauge 81 and second pressure gauge 82, by the pressure difference of two pressure gauges to determine whether there is leakage.
This step forms targeting verifying to the shock resistance of baffle plate, therefore can be to the shock resistance of baffle plate
Obtain reliable answer.
S3, Xiang Suoshu are verified the shell-side fluid for being mixed with impurity of injection nominal operation volume in shell-and-tube heat exchanger 1；It enables
Shell-side fluid is flowed through with the cycle of states higher than rated operating pressure and is verified shell-and-tube heat exchanger 1, is set to shell-side fluid circulation
It is discharged it after timing is long, judges whether to meet simultaneously that shell-side fluid pressure in cyclic process does not decline, baffle plate does not occur
Deformation, tube bank can not be swung in perforation and interbank nothing contacts with each other, if then determining that being verified shell-and-tube heat exchanger 1 is
Reliably, S4 is thened follow the steps if not.
The purpose of step S3 is to can be carried out verifying to the abrasion resistance of baffle plate and tube bank；Because in actual use, by
The influence of the factors such as galvano-cautery after diameter crosses long-time service, can be mixed with the impurity such as a large amount of fine sands, iron filings in shell-side fluid, long-term to rush
Brush friction leads to tube bank leakage, baffling dash-board injury.And this step makes the shell-side fluid for being mixed with impurity participate in shell side circulation, and cooperates
Flow regulating unit makes shell-side fluid form high speed liquid flow, tube bank outer wall and baffle plate is formed high intensity and washed away, due to carrying out
So far affirmative has been obtained in the shock resistance of the baffle plate of step, when executing this step equally also by shell-side fluid with two
The cycle of states of times rated operating pressure, which flows in and out, is verified shell-and-tube heat exchanger 1, terminates in the test process of this step
Afterwards, it deforms if shell-side fluid pressure decline, baffle plate in cyclic process occur again, restrain the swing in perforation or manage
The problems such as interfascicular contacts with each other, it can caused by judgement is the abrasion because of impurity.Therefore, this step can be to baffle plate and tube bank
Flushing resistance forms targeting verifying, therefore can obtain reliable answer to the flushing resistance of baffle plate.
It is unreliable that S4, judgement, which are verified shell-and-tube heat exchanger 1,.
It is every when executing to step S4, it can explicitly know and be determined as insecure reason, and then can be targeted
