Description
Technical field
The utility model is related to boiler exhaust gas flue gas ash removal, blast system dedusting, material conveying separate and collect field, specifically
Ground is said, is related to a kind of high pressure sealing baffle system.
Background technology
The field such as separate and collect in boiler exhaust gas flue gas ash removal, blast system dedusting, material conveying at present, generally use
It is cyclone separator, cyclone separator is made up of cylinder, cone, air inlet pipe, blast pipe and ash-unloading tube, and the gas of dust-laden enters rotation
After wind separator, the separation of gas and solid will be carried out, clean gas is discharged upwards by blast pipe after separation, and separated consolidates
Body is discharged downwards by cone to unloading valve.Because the Flow Field Distribution inside cyclone separator is extremely uneven, cause to be particularly
Cyclone separator cone position air turbulence, therefore some solid not separated can not arrange cyclone separator, cause
The Effiency of whirlwind Separator reduces, or even causes the serious consequences such as cyclone separator bottom conic-body blocked.
The content of the invention
The purpose of this utility model is to provide a kind of separative efficiency that can improve cyclone separator, prevents cyclone separator vertebra
The high pressure sealing baffle system that body blocks.
Realizing the technical scheme of the utility model purpose is：A kind of high pressure sealing baffle system, including cyclone separator, rotation
Wind separator is made up of cylinder, centrum, air inlet pipe, blast pipe and ash-unloading tube, and air inlet pipe and blast pipe are arranged on cylinder, unload ash
Pipe is connected to the bottom of centrum, and the bottom of ash-unloading tube is provided with gas lock rotary valve, and the bottom of gas lock rotary valve is provided with cement output tank, in gas
Communicating pipe is set between ash-unloading tube and cement output tank before and after lock rotary valve, high pressure positive blower is provided with communicating pipe.
Further, pressure transmitting sensor is provided with described cement output tank, PLC controls are connected with described high pressure positive blower
Device processed, pressure transmitting sensor provide signal to PLC.
After employing above-mentioned technical proposal, the utility model has following beneficial effect：
1st, during normal operation, gas lock rotary valve will be run according to certain speed, and the solid inside ash-unloading tube is uniform in time
Be discharged to cement output tank, prevent solid block ash-unloading tube；
When the 2nd, occurring abnormal, high pressure positive blower will be opened, and the gas inside ash-unloading tube is transported in cement output tank by blower fan, now
Cyclone separator cone position forms negative pressure band, and the solid at cone position be present will be transported in ash-unloading tube, pass through gas lock
Rotary valve is discharged, and the separative efficiency of cyclone separator is greatly improved, it is therefore prevented that the conic-body blocked of cyclone separator.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model high pressure sealing baffle system.
In figure, 1, cyclone separator, 1-1, air inlet pipe, 1-2, blast pipe, 1-3, cylinder, 1-4, centrum, 1-5, ash-unloading tube,
2nd, gas lock rotary valve, 3, high pressure positive blower, 4, pressure transmitting sensor, 5, PLC, 6, communicating pipe, 7, cement output tank.
Embodiment
In order that content of the present utility model is easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail to the utility model.
As shown in figure 1, a kind of high pressure sealing baffle system, including cyclone separator 1, cyclone separator 1 by cylinder 1-3,
Centrum 1-4, air inlet pipe 1-1, blast pipe 1-2 and ash-unloading tube 1-5 compositions, air inlet pipe 1-1 and blast pipe 1-2 are arranged on cylinder 1-3
On, ash-unloading tube 1-5 is connected to centrum 1-4 bottom, and ash-unloading tube 1-4 bottom is provided with gas lock rotary valve 2, the bottom of gas lock rotary valve 2
Portion is provided with cement output tank 7, communicating pipe 6 is set between the ash-unloading tube 1-5 and cement output tank 7 before and after gas lock rotary valve 2, in communicating pipe 6
On be provided with high pressure positive blower 3.
As shown in figure 1, being provided with pressure transmitting sensor 4 on described cement output tank 7, connected on described high pressure positive blower 3
There is PLC 5, pressure transmitting sensor 4 provides signal to PLC 5.
Operation principle of the present utility model is as follows：
1st, when the gas of dust-laden enters cyclone separator by tangential admission pipe 1-1, gas will be become by linear motion
Circular motion；
2nd, now the gas of dust-laden will produce centrifugal force in rotary course, after solid meets cylinder 1-3, just lose radially
Inertia force and be snapped down to cone 1-4 along wall, fall into ash-unloading tube 1-5 from cone 1-4, uniformly discharged by gas lock rotary valve 2, it is clean
Gas discharged by blast pipe 1-2；
3 but cyclone separator internal rotation air-flow from cylinder 1-3 to cone 1-4 when, the air-flow in cyclone separator
To become very disorderly, and have influence on the whereabouts of cone 1-4 positions solid, cause the solid after separation in cone 1-4 on
Low suspension stops gliding on cone 1-4 tube walls, causes conic-body blocked；Now high pressure positive blower 3 is opened, by ash-unloading tube 1-5
The gas of the inside is transported in cement output tank 7, and now cyclone separator cone position forms air compartment negative pressure band, originally in cone 1-4
Interior upper low suspension or the solid to be stopped gliding on cone tube wall, by the suction of air compartment negative pressure band, fallen from cone 1-4 is past
Enter ash-unloading tube 1-5, uniformly discharged by gas lock rotary valve 2；
Pressure transmitting sensor 4 is provided with cement output tank, by measuring the pipeline pressure in cement output tank, signal is transmitted
To the PLC 5 of high pressure positive blower 3, so as to control the rotating speed of high pressure positive blower 3 and air quantity, reach regulation separator cone portion
Position forms purpose of the air compartment negative pressure with parameter.
Particular embodiments described above, the purpose of this utility model, technical scheme and beneficial effect are carried out to enter one
Step describes in detail, should be understood that and the foregoing is only specific embodiment of the utility model, is not limited to this
Utility model, it is all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements done etc., it all should wrap
It is contained within the scope of protection of the utility model.
