Abstract
The present invention relates to a kind of when large coal-fired boiler dry collector ash hole samples automatically ensures the method for real-time, this method will be for, to the on-line checking of house outlet ash sample combustible content or ingredient, solving sample lag issues caused by being buried in ash due to sampling apparatus entrance in production process.It is characterized in that：A nozzle is respectively installed additional before and after the valve that strength sampler controls sampling quantity, after valve is closed, compressed air is each led into nozzle, blowback is emptied all old ashes into sampler by the compressed air being passed through before valve；The compressed air being passed through after valve by empty conveying ash sample channel in remaining old ash.Then, compressed air is each led by two nozzles of solenoid valve control pair, it will be able to ensure that the ash sample of acquisition is new ash at that time in due course.
Description
Technical field
The present invention relates to a kind of when large coal-fired boiler dry collector ash hole samples automatically ensures the side of real-time
Method, this method by for the on-line checking of house outlet ash sample combustible content or ingredient, solved in production process due to
The problem of sample lags caused by sampling apparatus entrance is buried in ash.
Background technology
The testing result of unburned combustible in fly ash will be for the real-time adjustment to boiler combustion in boiler combustion product.Cause
This, the real-time of the tested ash sample of acquisition just seems particularly significant.The present invention relates to sampling be deduster bucket shape ash
What the outlet in storehouse carried out.Since the entrance of sampler is embedded in flying dust, so collected sample is all upper one every time
It is supplemented in the old ash come at that time after a detection cycle sampling, meanwhile, some old ashes can also be remained by conveying the channel of ash sample.Therefore,
Ash sample collected in this way will be late by a detection cycle.
For the above reasons, prevent testing result from the requirement for meeting firing optimization to real-time, directly affect burning
The effect of control.
Invention content
In order to solve the problems, such as that ash sample acquisition lag, the present invention propose a kind of guarantee real-time in existing automatic sample mode
Method.
This method technical problems to be solved and the technical solution adopted is that：The valve of sampling quantity is controlled in original sampler
A nozzle is respectively installed after in front of the door additional, if each leading into compressed air into nozzle, to be passed through before valve after valve is closed
Blowback is emptied all old ashes into sampler by compressed air；The compressed air being passed through after valve will empty conveying ash sample
Remaining old ash in channel.Then, compressed air, energy are each led by two nozzles of solenoid valve control pair in due course
Enough ash samples for ensureing acquisition are new ash at that time.
Advantageous effect caused by the present invention is：Operative practice through the embodiment of the present invention proves that this method is effectively
It solves the ash sample lag issues acquired when dry collector ash hole samples automatically, testing result is enable to reflect pot at that time
The combustion position of stove provides reliable foundation for Combustion System and regulating effect and timely feeds back.
Description of the drawings
Attached drawing is unburned carbon in flue dust on-line period schematic device of the present invention.
In figure：1. 2. ash sample of compressed air, 3. 4. electric and pneumatic valve of deduster ash hole wall surface, 5. front nozzle
6. 7. ash sample conveyance conduit of rear nozzle, 8. strength sampler.
Specific implementation mode
Present invention will be further explained below with reference to the attached drawings and examples.
As shown in the picture：It is empty that the present invention has installed two compressions additional respectively on original sampler 8 and ash sample conveyance conduit 7
Gas front nozzle 5 and rear nozzle 6.Specific implementation mode is：Strength sampler 8 is fixed on deduster ash hole wall surface 3, even
Connect ash sample conveyance conduit 7；Electric and pneumatic valve 4 is closed before sampling, compressed air 1 is passed through to front nozzle 5, will be flowed into before
The old grey blowback of strength sampler 8 is removed, and after disconnecting compressed air 1, is passed through compressed air 1 to strength sampler 8 immediately,
Electric and pneumatic valve 4 is opened simultaneously, current new ash sample 2 is inhaled into strength sampler 8, and passes through ash sample conveyance conduit 7
It is transported to testing agency, the shut-in time of electric and pneumatic valve 4 how much is controlled according to sampling quantity, primary sampling, which is accused, to be completed.
After electric and pneumatic valve 4 is closed, it is passed through compressed air 1 to rear nozzle 6, remaining ash in ash sample conveyance conduit 7 is removed dry
Only, it is that sampling is ready next time.
By above example, solve the problems, such as that ash sample lags when dry collector ash hole samples automatically.
Claims (1)
1. a kind of method ensureing real-time when large coal-fired boiler dry collector ash hole samples automatically, it is characterized in that：
A nozzle is respectively installed additional before and after the valve that sampler controls sampling quantity, and after valve is closed, pressure is each led into nozzle
Blowback is emptied all old ashes into sampler by contracting air, the then compressed air being passed through before valve；The pressure being passed through after valve
Contracting air by empty conveying ash sample channel in remaining old ash.
