Description
【Technical field】
The present invention relates to it is a kind of be used for cleaning in central air-conditioning the cleaning system of the heat exchanging pipe of condenser, in particular to
A kind of on-line Full energy-saving cleaning system of water cooled condenser bead and its control method.
【Background technology】
Present invention is particularly directed to its own all systems in the art to add power source (such as：Add circulating pump, supercharging
Pump, air compressor machine etc.) come complete bead cleaning condenser service, receive ball power on-line cleaning system or device, while
That bead on-line cleaning technological system of Chinese invention patent 200310112606.6 including the applicant.
Any system its own add power source realize transmitting-receiving ball that bead on-line cleaning system all there is technology
Defect and serious security risk.
The nearly research and development in 20 years of team led according to the applicant dissect the major defect and security risk such as with practice
Under：
1, itself a large amount of power consumption, use cost are high when system operation；And the effect for being short of power, while serving a ball, returning serve
Fruit is not good enough, and the cleaning performance of condenser tubes is bad；
2, the pump etc. of added sending and receiving bead in high-frequency executes the startup of short time, closes for a long time in system, and opens
Dynamic closing motion again, the motor very rapid wear failure of pump, once power breakdown or damage, system or device are paralysed immediately
Paralysis, cleaning function failure, running condenser or heat exchanger interior conduit are irreversible also while continuous heat exchange
Dirt starts to adhere to fouling again, and time longer fouling is thicker during this, and rate of heat exchange declines to a great extent, at this time if restarted
It fixes or what renewal impetus source pumped clean, must cause the condensation pipe of large area that the bead of entrance is stuck in every root knot
In the pipeline of dirt, the very terrible consequences that condensation pipe is blocked by bead is caused, this will cause entire production of units to run
Paralysis stops the serious consequence of factory！
3, the technology for installing pony pump in all systems additional as transmitting-receiving ball power source all has one in operation workflow
A fatal technological deficiency consequence, by pony pump or booster pump to constantly supercharging forces the pressure in transmitter in ball transmitter
When power is higher than the internal pressure of cooling cycle pipeline, fluid and bead in transmitter just can the high cooling water pipelines of feed pressure successively
In, the bead being introduced into forms the linear formation Fast marching of constant space with laggard bead in quick cooling water,
Be formed when the condenser tubes that the small sphere of exterior rearview of linear traveling arranges big cross section honeycomb shape line opposite as a result, advanced
After the bead entered first passes through the wherein pipeline in condenser, laggard bead can also enter this root pipeline or side therewith
Pipeline, for this purpose, more beads also can only not passed through by bead by several pipelines few in number, most of pipeline again
It cleans, for this purpose, do not start continuous fouling as time goes by by the condenser tubes by scouring, once the row of floating shape
Into bead when into the pipeline of fouling, bead, which is just stuck in the pipeline of the fouling, causes the pipeline to block, but with when
Between elapse, the bead for returning to transmitter gradually decreases and most of bead blocks in condensation pipe and also causes to cause condenser
The plugging of heat exchanging pipe large area and the fearful serious consequence for losing its heat exchange function！
4, all power source systems for installing small circulating pump or booster pump etc. additional in system, the defect that work is run are
When starting the system operation, it is small with cooling water pipeline bypass road with designed formation to be introduced into the bead of cooling water pipeline
Ball cycle advances and does not stop when reaching ball transmitter and flow into cooling water advancing from ball transmitter with partial circulating fluid
In the cooling water pipeline of upstream side, laggard bead is similarly not stop inside ball transmitter to continue with partial circulating fluid land
It is continuous to carry out in cooling water pipeline again, therefore the bead of the system, when starting operation, a line is advanced not before and after just forming bead
Changeable state, when power source stops, the bead in these travelings is motionless also with fluid and respectively stops and fixes on side
On some position in the pipeline in road, when power source is restarted next time, fixes and rest on the bead of other pipeline each position again
Start to synchronize as partial circulating fluid is advanced, can not change the state that bead can only be cleaned by only a few condensation pipe always,
Lead to that system cannot cause the comprehensive cleaning of all pipelines of condenser, the defect generated instead that large area blocks it is serious after
Fruit.
In conclusion on the basis of above-mentioned background technology, after the applicant's patent of invention 200310112606.6,
It is automatic that the Chinese invention patent 201610417611.5 that the applicant applied in 2016 discloses a kind of condenser of central air conditioner

Step 3：Interval after forty minutes, is transferred to step 1.
The delivery of service of ball transmitter of the present invention terminates to be a wash cycle with return of serve action, daily automatic cleaning
Cycle 36 times.
The system fully automatic operation of the present invention is controlled by PLC program control devices, and PLC program control devices send out instruction unpack the
When one normally closed program-controlled valve 5, the huge discharge pressure of huge powerful cooling water circulating pump 300 is in special special construction mouth to mouth
Under state, powerful power source transient conduction first passage 31 gushes out bead in ball emitter chamber and fluid moment only
One can pass-out second channel 32, check-valves automatically opens, and goes out into cooling water system upstream side angle, complete bead moment collection
Body synchronizes eruption and enters in cooling water pipeline.
Bead collective gush out uniquely can during exit passageway second channel 32, ball transmitter first passage 31 only
It returns the second program-controlled valve 4 that is automatically closed in state and the second branch of third channel 33 of valve 311 and is also at normally off and formed
, unique basic element of the ball lift-off technology of the state-of-the-art bead on-line auto-cleaning in the whole world of the invention is realized, is shut out simultaneously
The serious sequelae risk of its defect and flaw absolutely.This is because spurting into cooling water pipeline from 322 collective synchronization of angle
The each pipeline that the heat exchange to condenser 200 could be very completed in 100 all cleans to.According to research and development experiment knot
Fruit：If not collective synchronization eruption bead enters cooling water system but the whole story causes fraction condenser into membership successively
Heat exchange pipeline iterates through scouring, and numerous pipelines does not generate fouling by bead by cleaning, and the heat exchange of slightly fouling is small
Pipeline bead is disliked once entering can block in pipeline and plugging, the bead being stuck are much fewer in the bead of cycle immediately
Property cycle occur immediately, heat exchange drastically declines, finally will occur serious safety accident serious consequence.
The bead of transmitting, which enters the circulation of fluid power in the cooling water pipeline of upstream side with Fast marching, to be completed to condenser
Pipeline reaches in return of serve controller 2 after cleaning and is stopped and rested in 2 ball room of return of serve controller by collective, and PLC is simultaneously emitted by again
Signal program controlled automatic controlled valve 5 close, program controlled automatic valve 4 open, due to huge cooling water circulating pump huge suction and
Most nearby special composition forms the resultant force work of huge Negative Pressure Difference at shape mouth to mouth for its upstream side higher-pressure region and downstream end pumping hole
Under, it is also to eject moment outside return of serve controller 2 to rest on the return of serve indoor bead of 2 ball of controller, through first passage 31
Collective returns to bead (by U-shaped poroid net in shell every blocking in upper chamber) in ball transmitting upper chamber, same to realize third channel 33
The composition in enormous motivation source completes the collection bead enormous motivation of ball transmitter.Due to the cooling huge Negative Pressure Difference of flow fluid and
Under the action of suction, from fluid and the bead moment in the ball controller of higher-pressure region spray to ball transmitting upper chamber it is U-shaped poroid online when,
Huge whirl rolling power is produced, like the washing machine of great power is adsorbed on dirt on bead by what is returned after scouring automatically
It is automatic to get rid of wash clean, complete the ball transmitting for uniquely having self cleaning function of small club in global this technical field of systems technology
Device device.If all there is the major defect that small club blocks condenser heat exchange tubes road in any system or device of no this function,
Because dirt can be adsorbed by being returned to after cleaning condenser tubes with bead in ball transmitter, wash clean is not got rid of when certain
Dirt on interior bead gradually becomes hard scale such as stone shape, and that causes to run counter to desire blocks the serious consequence of pipeline.Make certainly in bead
After my cleaning action, PLC instructions are closed the program controlled automatic controlled valve 4 and are closed, and complete its system without configuring power source
Return of serve and ball self cleaning technique.
Daily 36 cleanings of PLC designs have played conclusive key technology to effective performance of present system technology and have made
With.Because to ensure that every pipeline is comprehensive for cellular hundreds of thousands of small pipelines in condenser to clean to and ensure
Pipeline is throughout one's life the technology of the present invention most key, most crucial unique ultimate technology all in non-scaling clean state and invents this germline
The final purpose of system technology.Carefully solution is as follows for this core technology show-and-tell：Daily (24 hours) automatic cycle of PLC program setting
36 secondary frequencies are cleaned, primary at interval of 40 minutes automatic cyclic cleanings, each scavenging period (has calculated bead entrance in 5 minutes
Cooling system is with prevalence into, Cleaning pipes, bead self cleaning, the grace time needed for whole flow process)；Why to design daily
36 cleanings(1) this starts that dirty, the time of fouling is related with clean heat exchanging pipe；(2) also with it is false in a condenser
Need to project a how many beads if any 100 heat-exchange tubes goes cleaning just to can ensure that cellular every pipeline is comprehensive and all clean to
Position is related.This 2 points must could become correct effective skill with scientific knowledge and professional knowledge and engineering practice come R. concomitans
Art, otherwise good technological process again, then the system of each device synthesis rationally designed all can only be ornaments, or even endanger cooling system
It unites and causes safety accident of running counter to desire；Described (1) point, internal authority research institution have shown that：Clean heat exchange
Duct wall tube wall after booting operation 100 hours start to grow it is smooth slip biomembrane, or so 150 to 200 hours tube wall starts
Adhere to soft dirty crystalline solid, becomes increasingly thicker hard scale later.It is 5 times of hard scale that biomembrane, which hinders heat exchange,.This indicates 50
Hour it is relative clean to the present invention provides the premise foundations that technology solves with inner tubal wall；Described (2) point, 100
The condenser of pipeline need to project a how many beads and cleaning is gone comprehensive could to wash each pipeline100 beads of projection are done
Method does not allow！This has the cooling water flow flux by condenser because of the cooling water system of central air-conditioning extremely stringent
What safe design standard required, if 100 effective 100 balls block up shape into will produce pipeline when condenser tubes immediately entirely simultaneously
State, flow, pressure, circulation power, electric current and rate of heat exchange of cooling system etc. generate adverse reaction, host system immediately
Abnormal response is generated at once, this phenomenon air-conditioning system is often occurred and be will produce the mixed and disorderly direct entire air-conditioning system of crisis of system
Safety serious problems, therefore with convention understand 100 to 100 methods be impermissible for it is also unscientific.It is so small
Ball dosage, which has been lacked and every pipeline is not achieved, all washes, wash less than pipeline can slowly form thick dirt, once bead enters the knot
It can be blocked at once in dirty pipeline and block pipeline, being become by the more and more movable balls of the ball of card can be fewer and fewer, and the pipe being blocked is got over
Come more, vicious circle is directed at heat exchange forfeiture, and high pressure constantly rises in system container, and catastrophic consequence is beyond imagination.Cause
This in summary the present invention use the bead quantity that 100 pipelines project every time for 30 balls, allow 70% the unimpeded flow of pipeline
Amount requires standard to meet the minimum cooling flow of condenser, and 30% ball is allowed to manage the control skill all cleaned in place to complete every
Art can be broken through with 36 frequency techniques of daily cleaning and solve what the research and development test of this above-mentioned road difficulty and n times was verified
The technology of can be achieved, the foundation that it is realized are calculated with Probability and are completed, and probability calculation is as follows：
The radical of ball number/100：30% bead
Each clean cycle interval time number：40 minutes
Interior ball cycle-index in 50 hours before pipe dirt：75 times
A ball is not by the probability of a pipe in one cycle：7/10 or 0.7
A ball is not fallen to by the probability of a pipe in being recycled at 75 times：
=(0.7)75
=2.4 × 10-12 or 0.0000000000024
Opposite, a ball is by the probability of each pipe in 100 pipes within 50 hours：
=1-0.0000000000024
=0.9999999999976 or 99.999%
=100%
Therefore the present invention uses the bead quantity that 100 pipelines project every time for 30 balls.
