But the fly ash comprehensive application that the coal-burning power plant produces needs ash transfer standby to the grey storehouse of storage.Because operational throughput is big and distance, needs bigger delivery pressure and just can finish the conveying task.The malleation concentrated phase pneumatic ash removal system of large coal-fired power plant generally adopts imported technology.Reality in conjunction with China; the ature of coal that the coal-burning power plant uses is changeable; ash content increases considerably and requires to carry the super large of exerting oneself; malleation concentrated phase Pneumatic ash conveying system is difficult to adapt to; take place to carry latch up phenomenon and electrostatic precipitator storage ash bucket inner product press-powder coal ash to make the powder position reach dangerous high charge level through regular meeting; seriously threaten the safe operation of power plant; the storage ash bucket that is forced under the electrostatic precipitator is promptly put ash on the spot; and cause gross pollution; or reduce the load of generator set, these phenomenons developed into leave no choice but to solve can not stage.For this reason, quantitative malleation pneumatic ash removal system can be changed into the defeated grey mode of the discontinuous concentrated phase that with the storehouse pump is main transport box the quantitative malleation pneumatic ash removal system of no storehouse pump receptacle, has thoroughly overcome the various drawbacks of being brought by the malleation concentrated phase pneumatic ash removal system of external introduction.
Summary of the invention
The objective of the invention is: the coal-burning power plant is still carried out malleation concentrated phase pneumatic ash handling as the secondary reservoir vessel generally adopting with the storehouse pump at present, and quantitative malleation pneumatic ash removal system cancellation storehouse pump and charging and discharging valve, replace it with electronic baffle door, solid powder flow monitoring device and mixer, change into quantitative malleation pneumatic ash removal system, to overcome with the storehouse pump is the malleation concentrated phase pneumatic ash removal system of main transport box, threatens the safety and economic operation of electric dust collector because of carrying undercapacity.Quantitative malleation pneumatic ash removal system not only can improve the defeated grey ability of ash disposal system and can monitor defeated grey flow regime and ash/gas ratio, also can save storehouse pump and charging and discharging valve thereof and relevant annex and equipment thereof, reduces the quantity of ash conveying pipe.
The present invention solves the technical scheme that is adopted that has problems in the ash transfer: simplify pneumatic ash removal system, electronic baffle door and solid powder flow monitoring device string are contained on the ash tube under the electrostatic precipitator storage ash bucket, at mixing tube and ash conveying pipe intersection jet pipe is housed, pressurized air produces the effect of inhaling volume fly ash by jet pipe, fly ash is sent into ash pipeline be delivered to the grey storehouse of storage.
Description of drawings
Be described further below in conjunction with drawings and Examples.
Accompanying drawing is the formation of quantitative malleation pneumatic ash removal system:
1. 3. maintenance of storage ash bucket 2. level-sensing devices constitute quantitative malleation pneumatic ash removal system with insertion plate door 4. electronic baffle door 5. solid powder flow monitoring devices 6. gas equalizing pipes 7. ash tubes 8. jet pipes 9. mixing tubes 10. oblique cutting pipes 11. flow counter 12. forcing pipes 13. ash pipelines 14. air intake valves.
The specific embodiment
In the accompanying drawing, the sidewall position of storage ash bucket (1) middle and lower part is provided with level-sensing device (2), maintenance insertion plate door (3) is housed under the storage ash bucket, be equipped with electronic baffle door (4) and solid powder flow monitoring device (5) under it, ash tube (7) connects with mixing tube (9), diffuser pipe (10) is equipped with in the mixing tube lower end, when the fly ash that the electric dust exhaustor is collected can detect the ash position at level-sensing device (2), suitable angle is just opened and adjusted to electronic baffle door (4) automatically, make fly ash through solid powder flow monitoring device (5), recording the instant flow rate value is that the maximum quantitatively concentrated phase that satisfies ash-transmission system is carried, when the fly ash that stores up the ash bucket storage satisfies the condition of maximum quantitatively concentrated phase conveying inadequately, electronic baffle door (4) SELF CL, air intake valve (14) on the while closes compression air pipe is to save compressed air consumption, when level-sensing device (2) detects the ash position of fly ash once more, again electronic baffle door (4) is opened the aperture of recovering original, repeated above operation.When the powder position of storage ash bucket is in dynamic powder position, make transportation work always remain on the operation continuously down of maximum defeated ash amount concentrated phase state, only when dynamic powder position is in the condition of not enough maximum quantitatively concentrated phase conveying, just stop the supple of gas or steam to suspend and carry, the dynamic powder position of waiting to store up ash bucket runs up to the material level timing and begins to carry by the maximum delivery concentrated phase again, dangerous high charge level will not appear in the storage ash bucket, guarantees that ash disposal system can be in operation under the energy-saving safe state.At gas equalizing pipe (7) and storage ash bucket (1), electronic baffle door (4) and solid powder flow monitoring device (5) the maintenance air pressure balance that is interconnected, fly ash is after discharge measurement, fall into the mixing tube (9) that has jet pipe (8) by ash tube (7), jet pipe can produce swabbing action, make fly ash fall into mixing tube, send into ash conveying pipe through the malleation pressurized air, can be controlled in the scope of concentrated phase conveying by ash (kg)/gas (kg) ratio, fly ash and compressed-air actuated compound enter ash pipeline (14) through diffuser pipe, ash pipeline is provided with forcing pipe (12), can adjust air intake valve (14) according to the situation of ash transfer and satisfy conveying, the powder that each storage ash bucket sends can be together in series by ash pipeline and directly be delivered to the grey storehouse of storage.In a single day ash pipeline has clogging phenomenon to take place, and it is stifled to carry out blowback automatically by gas equalizing pipe (6), can recover normal conveying automatically behind the pipe-dredging.
Carry fly ash continuouslyly and unobstructedly, can reduce the heat dissipation of fly ash, help flowing of fly ash, thereby be difficult for blockage phenomenon.The defeated ash load of the ash disposal system of original discountinuity is big, causes electrostatic precipitator storage ash bucket to overstock fly ash easily material level is raise, and forces until high charge level and promptly puts ash or reduce unit load.And improved continuity is carried, and has disperseed concentrated force, thereby phenomenon can not take place to overstock.Even if the increase at double of quality decline ash content, defeated grey ability also can satisfy, and the storage ash bucket can not produce high charge level and promptly put grey phenomenon, ensures that ash-transmission system can be in the state smooth operation of energy-saving safe.
