109 air feeds.Air inlet at each of which air compartment arranges valve, and this valve is slide valve, electromagnetic valve tie
Close YE and control its aperture, and electromagnetic valve is by line connection control center.This valve is also pacified
Equipped with operation handle, workman's manual operations can be facilitated.So the air quantity of each air compartment, blast can be only
Vertical adjustable.
Control centre is separately positioned on left side air compartment 104, intermediate plenum 105 and right side by connection
The Pressure gauge of the first pressure tap 111 of air compartment 106 and be arranged on the second pressure tap of the burner hearth first half
The Pressure gauge of 112, and monitor the force value of the two, the pressure reduction when therebetween reaches to set threshold pressure differential
Time, then start electromagnetic valve and touch the keying that YE controls the slide valve of slag dropping tube 103, carry out
Deslagging, slide valve 103 can also be carried out deslagging by Artificial Control.Control centre is according to the first pressure tap
Manometric force value monitor pressure when exceeding setup pressure value, then start electromagnetic valve and touch electronic
Executor controls the aperture of the air inlet valve of corresponding air compartment to regulate its intake.
The horizontal air distribution plate 108 of zone line is conventional fast fluidization region, the inclination cloth of both sides/surrounding
Aerofoil 109 is selectivity air distribution plate.Inclined distributor 109 scum pipe 103 below is disposed adjacent to
Outward flange side, is still respectively provided with as a example by scum pipe 103 by the left and right sides and illustrates, left side deslagging
Pipe 103 is a1 to the distance of left side edge, distance b1 of right side scum pipe 103 to right side edge；a1、
B1 can be equal or unequal.The horizontal stroke of left side air compartment 104 for inclined distributor 109 air feed in left side
The width in cross section is a2；The cross section of right side air compartment 106 for inclined distributor 109 air feed on right side
Width be b2；The cross section of intermediate plenum 105 for horizontal air distribution plate 108 air feed of zone line
Width be W.
Above-mentioned size meets following condition:
A1=(1/3～1/5) a2
B1=(1/3～1/5) b2
A2+b2=(1/2～2) w
Operation principle of the present utility model is as follows:
When running, the combustible on its top, slag and noncombustibles are blowed to by horizontal air distribution plate 108
In the air, become fluidized state, run to furnace height direction, when running to certain altitude, due to granule
Mutually colliding between the weight of self and granule, momentum reduces, and bulky grain thing starts downwards, transports to surrounding
Dynamic, formation material is mixed to be returned, and bulky grain thing finally drops back into the inclined distributor 109 that both sides/surrounding is in tilted layout
On.
The bulky grain thing piled up, can increase the resistance on inclined distributor 109, now control this part
Air compartment blast pressure head strengthen.It is welded with some towards the orientation wind tilted on inclined distributor 109
Cap, the blast so strengthened blows afloat these bulky grain things piled up by these wind caps so that it is continue
Afterflow, in order to make it as much as possible by after-flame.
When blast is added to its setting upper limit, need in time slag and noncombustibles to be drained.The row of opening
Slide valve on slag pipe 103, carries out deslagging.Owing to slag-drip opening is positioned at the minimum of inclined distributor 109
Point, when scum pipe 103 is opened, its internal pressure is the lowest identical with air, owing to being just on air distribution plate
Pressure, superatmospheric, the slag now becoming fluidized state will be the same by height to liquid with noncombustibles
Nip flows to the slag-drip opening that pressure is relatively low, it is achieved deslagging.
After most slag and noncombustibles are discharged by scum pipe 103, it is connected to cloth wind
The resistance of the air compartment of plate 109 can reduce rapidly, and at this moment blast pressure head will reduce, in order to avoid causing level
Slag and noncombustibles on air distribution plate cannot be streamed on inclined distributor, cause material to blow sky.
By above-mentioned the technical solution of the utility model it can be seen that this utility model utilize wind cap and
Non-isobaric air compartment air distribution realizes selective deslagging, utilizes the sizing blast cap on both sides/surrounding inclined distributor
Bulky grain thing is discharged in time with Large Diameter Pipeline scum pipe.
Selective deslagging device of the present utility model, is suitable at the coal containing more non-combustible granule, bastard coal
Stone, the occasion of the solid fossil fuel such as oil shale uses.It is particularly suited for containing more non-combustible particulate matter,
And the boiler combustion containing coal gangue fuel uses.
