Description
Technical field
The present invention relates to a kind of coal-burning boiler side-suction type is comprehensive from dust suppression and recovery system, coal-fired pot can be widely applied to
In the dry dreg removing system of bottom slag.
Background technology
In the existing dry dreg removing system of coal-burning boiler bottom ash, the influence for reduction flying dust to environment, discharging bulk machine is set
Blower negative pressure dust-arrest device；The main deficiency of blower negative pressure dust suppression has：One is serious wear of the lime-ash to blower fan, equipment life low-dimensional
Shield amount is big.Two be fan outlet access slag storehouse, reclaims flying dust, therefore slag storehouse needs to increase sack cleaner, increases system cost
And energy consumption.Three be that a large amount of cold wind enter dry slag system, uncontrollable.Moreover, during entrucking, under gravity, lime-ash impact self-unloading
Reentrainment of dust caused by car wagon box can cause substantial pollution, and secondary pollution has become the main environmental issue of dry slag system.
The content of the invention
It is an object of the invention to provide a kind of service life length, the coal-fired pot for reclaiming flying dust, eliminating secondary pollution, environmental protection
Furnace side suction is comprehensive from dust suppression and recovery system.
In order to achieve the above object, coal-burning boiler side-suction type of the present invention is comprehensive from dust suppression and recovery system, including fuselage
Horizontal segment is arranged on the air-cooled dry type slag conveyer of coal-burning boiler bottom, under air-cooled dry type slag conveyer fuselage tilting section top
The slag storehouse of side, the device for discharging installed in slag orlop portion, the bulk machine installed in device for discharging bottom, installed in bulk machine top
Sub- sweep-up pipe on air outlet, female sweep-up pipe on sub- sweep-up pipe is inhaled installed in female sweep-up pipe bottom and with some
Many Confucius's sweep-up pipes of dirt aperture, the bottom-up air-quantity adjusting valve being sequentially arranged on female sweep-up pipe, air quantity flowmeter, one
End is located at air-cooled dry type slag conveyer fuselage interior and the air main being connected with female sweep-up pipe top, and master is sequentially arranged at from left to right
Axial flow blower, main air-quantity adjusting valve, main air quantity flowmeter on airduct.
Coal-burning boiler side-suction type of the present invention is comprehensive from dust suppression and recovery system, described many Confucius's sweep-up pipes, positioned at scattered
Around installation, in closed.
Coal-burning boiler side-suction type of the present invention is comprehensive from dust suppression and recovery system, described bulk machine, including internal channel, outer
Passage and several level connection joint bolts that internal channel and outer tunnel link together；Described internal channel, including it is several big
Under small conical tube and the interior tubular flexible knitting thing outside conical tube；Described outer tunnel, including interior tubular flexible knitting
Thing and the flexible fabric of outer cylindrical；Described several level connection joint bolts, are radially sequentially passed through and the flexibility establishment of fixed outer cylinder shape
Thing, interior tubular flexible knitting thing and conical tube.
Coal-burning boiler side-suction type of the present invention is comprehensive from dust suppression and recovery system, described interior tubular flexible knitting thing, if
Put several inner circular wire loops.
Coal-burning boiler side-suction type of the present invention is comprehensive from dust suppression and recovery system, described outer cylindrical flexible knitting thing, if
Put several outer ring wire loops.
Coal-burning boiler side-suction type of the present invention is comprehensive from dust suppression and recovery system, and its operation principle is：When the discharging of slag storehouse,
To improve dust removing effects, the closing of material unloaded operation region.Axial flow blower rotating speed should be reduced or by the main air quantity on air main
Control valve is closed.The dust produced during discharging, a part of dust is under air-cooled dry type slag conveyer suction function, into bulk machine
Outer tunnel, be discharged to successively through sub- sweep-up pipe, female sweep-up pipe, air main inside air-cooled dry type slag conveyer；Meanwhile, another part dissipates
The dust fallen in closed area, under the synergy of many Confucius's sweep-up pipes, further dedusting equally, is eventually entered into air-cooled
Inside dry-type slag-conveying machine.Reach and reclaimed flying dust, eliminate secondary pollution, the purpose of environmental protection.After discharging stops, mother should be closed
Air-quantity adjusting valve on sweep-up pipe, starts axial flow blower, main air-quantity adjusting valve, passes through the main air quantity flowmeter on air main
Detection enters the total blast volume of boiler, realizes the air quantity contrast regulation of air quantity and bottom ash cooling the need for negative pressure dust suppression.
Coal-burning boiler side-suction type of the present invention is comprehensive from dust suppression and recovery system, soft using the flexible fabric of inside and outside tubular
Property fabric can be realized flexible, and braid has seal.Because flexible knitting thing has flexibility, it can produce under pressure
Deformation, to avoid channel blockage, the inside and outside circular steel wire ring of setting spaced apart improves braid circumferencial direction rigidity, protected
Its cylindrical shape is held, service life is long, and internal and external channel keeps passage unimpeded under pressure.
Coal-burning boiler side-suction type of the present invention is comprehensive from dust suppression and recovery system, described bulk machine, internal channel furnace conveyor
Slag material, the air of outer tunnel conveyer belt dust.
In summary, coal-burning boiler side-suction type of the present invention is comprehensive from dust suppression and recovery system, and service life is long, reclaims and flies
Ash, eliminates secondary pollution, environmental protection.
