In driving mechanism, on the output shaft of motor 10 bevel gear is installed, this bevel gear and the bevel gear engagement that is installed on the hollow rotating shaft 17.Eseparation ring 6 is horn-like, and the big end of eseparation ring 6 is downward, several eseparation ring 6 mutual back-off stacks; Between the upper end of upper end of separating hub 7 and seperator shell 8, back-diffusion and guide housing 5 are set.The hemispherical of back-diffusion and 5 one-tenth back-offs of guide housing.On hollow rotating shaft 17, be provided for coordinating separating the adjusting device 9 of the motor speed of hub motor 10 and blower fan 4.
Among the figure: 1, air compressor is used for former ash bucket is floated the air machinery that pearl ash mixture is delivered to separation bin; 2, insulation removes ash bucket, is used to store the former grey storehouse of floating the pearl ash; 3, air injection device floats the conveying equipment that the pearl ash is delivered to separation bin former ash bucket is mixed; 4, the pearl blower fan is floated in suction, and the equipment that the outer cleaning treatment of separation bin is gone into and carried to the pearl aspiration is floated in the delay of separation bin; 5, back-diffusion and guide housing tentatively spread the gaseous mixture of sending into separation bin through the back-diffusion pipe nipple, and even distribution falls into the separation hub; 6, non-return blinds eseparation ring, be flyash and separate float the pearl separation barrier, make the coal ash of having separated be difficult to reflux; 7, separating hub, is the main element of separation bin, and there is axial ripple on shape such as mitriform surface, produces centrifugal force during rotation, the coal ash of blending agent with float pearl and should accept centrifugal force and vary in size and separate; 8, seperator shell is the foreign exchange bulkhead of seperator, the coal ash outlet is arranged and float the pearl air stream outlet by law of segregation; 9, adjusting device is that the adjusting that separates hub motor and blower motor rotating speed is coordinated; 10, speed-regulating actuator provides power for the separation hub; 11, hydraulic ejector is to utilize the water-aspirator pressure hydrodynamic force to spray, and the pearl air-flow that floats of induced-draught fan outlet is sent into the pond and carried out water and clean to get rid of and may be mixed in the tiny coal ash that floats in the pearl air-flow floating pearl floating pearl; 12, centrifugal pump provides press water for the waterpower injector; 13, float the pearl service sink, clean and float pearl; 14, frame makes up the bearing support of this device; 15, blow-off pipe is got rid of the coal ash that washes down.
The little ash of general power plant gets off just to have machinery or air conveyor to be delivered to grey storehouse from deduster.The utility model is arranged in the Hui Ku top in principle.The flyash of sending here from deduster before warehouse-in, middle this device that inserts, the little ash after the separation is put in storage again.Float pearl and go into to float the Zhu Chi cleaning.
Little ash mainly is that unit weight according to little ash is at 0.7T/m with floating separating of pearl
3About, and the unit weight that floats pearl is at 0.25-0.4T/m
3, according to the bulk density difference of these two kinds of materials, it is floating principle that water separates, it is the simplest and effective that yes.But its shortcoming must be sacrificed the activity of little ash, because in a single day little ash runs into water, has just lost value.Therefore, want to float in the process of pearl, do not sacrifice the activity of little ash simultaneously, must do separation in separation.
Doing to separate mainly relies on the bulk density difference that floats pearl and little ash to carry out Gravity Separation and centrifugation.This device is based on centrifugation.
Has wavy surface above the centrifugal hub of separation bin.When the combination ash air-flow was flowed from top to bottom by the powder feeding pipe introducing, because the expansion of flow area, flow velocity reduced, and the little ash of part is separated under the gravity effect.And the combination ash air-flow continues to descend, and enters rotor region, rotates under the drive of rotor.Soot particle is big because of volume to weight ratio floats pearl, is subjected to big action of centrifugal force, is thrown the outside of tubaeform eseparation ring 6, and along the inwall whereabouts of seperator shell 8, the lock gas batcher through being installed on little ash bucket 16 lower ends is discharged into little grey storehouse.Float pearl then in the inboard of eseparation ring 6 along with air-flow is inhaled pearl blower fan 4 and hydraulic ejector 11 injects service sinks 13 through the passage of 8 on back-diffusion and guide housing 5 and seperator shell.
When flyash by air injection device 3 after 17 inputs of ash conveying pipe and hollow rotating shaft separate between hubs 7 and the eseparation ring 6, because it is big that volume becomes, flow velocity reduces, gravity effect because of little ash, the little ash of part falls to separating, enter following little ash bucket 16, inhale pearl blower fan 4 because unit weight gently continues to rise to enter with air-flow and float pearl.
Again the function of several critical pieces is described below.Separation bin mainly separates hub 7 and blinds eseparation ring 6 and seperator shell 8 according to the former reason of dilatation reduction of speed Gravity Separation and centrifugation and forms.After flyash enters this separation bin, separate hub 7 rotations and produce centrifugal force, the bigger little ash of unit weight is thrown to the separation bin inwall and entered little ash bucket 16 along the inwall downslide; Unit weight is less floats pearl and then is trapped in blinds eseparation ring 6 inboards and inhales pearl blower fan 4 by the separation bin top and suck and drain into and float pearl service sink 13.
Blinds eseparation ring 6 is mainly used in to be separated little ash and floats pearl, and the little ash in eseparation ring 6 outsides slips into little ash bucket 16 along the separation bin bulkhead, and the inlet of pearl with air-flow inflow separation bin top blower fan 4 floated in the inboard, squeezes into service sink 13 through blower fan 4.
Hydraulic jet pump 11 has two effects: the one, and utilize suction chamber that lighter abundant the mixing with water of pearl of floating of unit weight reached the cleaning purpose.The 2nd, suction chamber causes vacuum, can floating the smooth extraction of pearl air-flow and injecting service sink 13 separation bin.
Float pearl service sink 13 and be and utilize the light floatation characteristic of unit weight of floating pearl, flotation is cleaned in the pond, simultaneously, separates floating the residual little ash that the pearl air-flow is mingled with, and guarantees to float the purity quality of pearl.
With the 300MW generating set is example, more than 3000 ton of coal of about burnup every day, about more than 600 tons of the little ash that is produced, contain in the general little ash of coal that to float pearl about 1%, so as separate well, can receive that the 2-4 ton floats pearl every day, per tonly float pearl by 2000 yuan of calculating of market price, take in every day about 6000 yuan, annual by operation ratio calculating in 300 days, can take in 1,800,000 yuan every year.General this covering device of Installation in Plant can both be recouped capital outlay about a season.
