End is tightly connected the gas inlet pipe of cyclone separator 5, and the exhaust pipe 55 of the cyclone separator 5 is equipped with air-introduced machine 6, described to draw
The air outlet of wind turbine 6 is sealedly connected with return air duct 7, the air intake passage of the other end of the return air duct 7 and the extraction device 3
312 are tightly connected, and the ash releasing tube of the cyclone separator 5 is connect with the ash-storing bin 2.
The extraction device 3 enters pipeline 31 including dust, and the side that the dust enters pipeline 31 is equipped with dust discharge pipe
Road 32, the dust discharge line 32 are connect with the ash sucking tube road 4, and the dust enters one end of pipeline 31 and enters for dust
Mouth 311, the other end that the dust enters pipeline 31 are equipped with air intake passage 312；The air intake passage 312 and the return air duct
7 connections, the dust enter the place that 31 inside of pipeline connects with the dust discharge line 32 and are equipped with inclined fixed plate 33,
The fixed plate 33 is equipped with expansion plate 34；The expansion plate 34 is equipped with elongate slots 341, and the fixed plate 33 is stretched with described
It is equipped with adjusting bolt 35 between plate 34, the adjusting bolt 35 passes through the elongate slots to connect the fixed plate 33 and described flexible
Plate 34；The expansion plate 34 can be adjusted by the elongate slots and the adjusting bolt 35 its with the fixed plate 33 opposite position
It sets to adjust the size of extraction device dust outlet 36；The position change institute of the expansion plate 34 can be adjusted according to dust concentration
The size for stating extraction device dust outlet 36, so as to adjust the flow direction and flow velocity of air-flow, to adapt to the dedusting of different dusts amount
It needs, prevents the deposition of dust from blocking pipeline；The inner wall that the dust enters pipeline 31 is equipped with curved baffle 37, the baffle
37 one end, which is located at the top of the air intake passage 312 and enters the inner wall of pipeline 31 with the dust, to be fixedly connected, the gear
The other end of plate 37 and the top for being located at air intake passage 312；This designs the first effect that can more preferably allow big dust to generate explosion
Fruit, the second flow direction that can be oriented to air-flow allow dust more preferably more thoroughly by the air-flow band of the extraction device dust outlet 36
It walks.The air intake passage 312 is connect with the return air duct 7, the wind-force of the return air duct 7 can will fall into the dust into
The dust band for entering 31 bottom of pipeline is moved up and is not deposited, is then taken out of by the air-flow of the dust discharge line 32, it is therefore prevented that powder
The phenomenon that accumulation that dirt enters 31 bottom of pipeline in the dust blocks, effectively whole dust are discharged.
The cyclone separator 5 includes holder 51, and the holder 51 is equipped with divergent-cone wall 52, the divergent-cone wall
52 upper end is equipped with cylindrical tube 53, and the tangential direction of the upper end of the cylindrical tube 53 is equipped with gas inlet pipe 54, institute

The bottom end of exhaust pipe 55, the divergent-cone wall 52 is equipped with dust outlet 56, and the dust outlet 56 connects with the ash-storing bin 2
It connects.When dust-contained airflow generally enters the cyclone separator 5 with 12-30m/s speed by the gas inlet pipe 54, air-flow will
Circular motion is become from linear motion, the overwhelming majority of swirling eddy is twist downward along the inner wall of the cyclone separator 5
It is flowed towards the divergent-cone wall 52, in addition, particle under the influence of centrifugal force, is thrown toward wall, grit once connects with wall
It touches, just loses inertia force, and the momentum of the speed axially downwards near wall falls along wall surface, into the dust outlet
56, it is fallen into the ash-storing bin 2 by the dust outlet 56.
The outer rotational gas flow declined is rotated, is constantly flowed into the central part of the cyclone separator 5 during declining, shape
At centripetal radial air flow, this fraction, which just constitutes, rotates upward inward eddy, and the direction of rotation of inside and outside eddy flow is identical
, final purification gas is discharged through the exhaust pipe 55 outside the cyclone separator 5, the relatively dustshot that a part is not separated
Also it escapes therewith, but the present invention is connect by the return air duct 7 with the exhaust pipe 55 of the cyclone separator 5, not
It can be entered in the extraction device 3, will not be arranged with the exhaust pipe 55 by the relatively dustshot that the cyclone separator 5 detaches
Enter and pollutes air into air.
The inner wall in the ash sucking tube road 4 is equipped with a floor height temperature wearing layer, and the high-temperature wearable layer can be directly described
Ash sucking tube road 4 inner-wall spraying, one layer of high temperature abrasion material, the KN99898 that the high temperature abrasion material is for example sold on the market
Ceramic particle coating etc. can select the high temperature abrasion material of different cost performances as needed.
It is equipped with the first unloading valve 8 between the outlet and the import of the extraction device 3 of the receiver bin 1.The cyclonic separation
The second unloading valve 9 is equipped between the ash releasing tube of device 5 and the ash-storing bin 2.
The parameter values in the ash sucking tube road 4 and the return air duct 7 in the present invention（Such as diameter and length）
It can be adjusted according to actual place demand.It can be in the ash sucking tube road 4, the return air duct 7 according to place demand
The middle design for increasing bend pipe, the connection between the bend pipe can directly use flanged joint, naturally it is also possible to alternatively
Other manner is attached, and entire pipeline is made to form confined space.
Dust enters the extraction device 3 by the receiver bin 1, is conveyed by the ash sucking tube road 4 after being mixed with air
Into the cyclone separator 5, by the treatment and purification of the cyclone separator 5, purified gas passes through the air-introduced machine 6
It is pressurized to the return air duct 7, is entered in the extraction device 3 again by the return air duct 7 is last.Pass through in the whole process
The pressurization of the air-introduced machine 6 makes the ash sucking tube road 4 form negative pressure, dust in the ash sucking tube road 4 because the effect of negative pressure not
It can reveal, thus dust will not be caused to reveal and polluted to air 4 poor sealing of ash sucking tube road, it is described
Return air duct 7 forms high pressure, and the generation of pressure difference is to allow the ash sucking tube road 4 and the return air duct 7 to generate the stream of air
It is logical, prevent dust from precipitating in the duct.Whole process forms a hermetically sealed circuit, and no air is discharged in air, will not
The air of surrounding is polluted, ambient enviroment is protected.
