Description

Technical Field

[0001] The invention relates to the technical field of dust removal and jarring equipment, and more particularly to a dust removal and jarring equipment and a dust removal method for a garbage incineration fly ash storage bin. Background Art

[0002] Fly ash storage silos are facilities used to store fly ash generated by combustion equipment such as incinerators. Fly ash refers to the non-combustible components in the fuel and some incompletely burned fine particles that are collected after being discharged with the flue gas during the high-temperature combustion of garbage. This ash usually contains high levels of heavy metals and other harmful components, so it requires special treatment and safe storage. Since the fly ash storage silo is connected to the feeding system, a dust removal device will be installed on the top to prevent dust and balance the internal air pressure, but cleaning the dust removal device after use is a troublesome problem.

[0003] The Chinese patent application number is 201610492247.9, which discloses a fly ash filter dust removal device, which includes a dust collector body, a valve disposed at the air inlet end of the dust collector body, and a valve disposed at the air outlet end of the dust collector body, and a pressure regulating mechanism connected to the dust collector body and used for dust removal is disposed on the side wall of the dust collector body. The above device has the function of cleaning the filter element.

[0004] The Chinese patent with application number 202111231753.X discloses a shock-type dust collector, the structure of which includes a dust removal component, the dust removal component includes a dust collector and an ash bin, the ash bin is installed at the bottom of the dust collector, and a solenoid valve is arranged at the bottom of the ash bin; and a cleaning component, the cleaning component includes a backflush pipe, a shock mechanism and a guide pipe, the backflush pipe is installed in the top space in the dust collector and corresponds to each column of dust bags, the backflush pipe is provided with multiple openings, the shock mechanism is arranged on the outer wall of the dust collector and connected to the backflush pipe, the shock mechanism is located in the dust collector and one side extends out of the dust collector to connect the guide pipe. The above-mentioned equipment is provided with a beating device and a backflush device, which can play the role of airflow cleaning for the filter bag.

[0005] The filter bag cleaning device on the fly ash storage silo still has the following problems: 1. After the airflow carrying fly ash enters the fly ash storage bin, part of the airflow will flow along the top of the fly ash pile, causing the settled fly ash to be stirred up again, indirectly increasing the filtration capacity of the top filter bag.

[0006] 2. A cleaning device is provided inside or on the top of the filter bag, but it is not convenient to clean the filter bag in use, so the filter bag needs to be stopped for cleaning every time it is used for a period of time, which increases the working time of the equipment and reduces the working efficiency.

[0007] 3. The airflow after passing through the filter bag will continue to move upwards and then be discharged through the pipe. As the dust accumulates on the surface of the filter bag, it will affect the airflow inside the filter bag and affect the filtration efficiency.

[0023] 4. The device is provided with a centrifugal disk component at the bottom of the filter bag. The centrifugal disk guides the airflow outside the filter assembly downward through rotation to prevent the cleaned fly ash particles from moving upward.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention, that is, the embodiments described are only part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0027] Depend on Figures 1 to 12The present invention provides a method for storing fly ash from the incineration of garbage, and comprises an ash storage tank 101, which is used to store fly ash after the incineration of garbage, and an ash discharge port is arranged at the bottom. One side of the ash storage tank 101 is connected to an air intake frame 102 which is connected to the inside, and one side of the air intake frame 102 is connected to an air intake pipe 103, and the air intake pipe 103 is connected to the fly ash conveying pipe outside, which is a feed port. The inside of the air intake frame 102 is connected to a fly ash baffle 104, which blocks the gas just entering. The fly ash particles in the gas will collide with the fly ash baffle 104 due to the inertia, and the fly ash particles above will fall on the fly ash pile at the bottom after accumulating to a certain extent. The inside of the ash storage tank 101 is connected to an airflow guide frame 105, and the airflow guide frame 105 is eccentrically arranged in the ash storage tank 101, and moves away from the end away from the air intake pipe 103, thereby increasing the efficiency of the ash storage tank 101. The airflow at the inlet moves upward, and the function of the airflow guide frame 105 is to guide the airflow upward, so that after the airflow passes through the airflow guide frame 105, it will move from the top to the filter assembly. The bottom of the airflow guide frame 105 is provided with a plurality of holes for the fly ash particles to move toward the ash discharge port below. The top of the inner wall of the ash storage tank 101 is connected with a top plate 106, and the top of the outer wall of the ash storage tank 101 is connected with an airflow outlet pipe 107 connected to the top of the top plate 106. The airflow outlet pipe 107 is used for the discharge of airflow. The bottom of the top plate 106 is connected with filter assemblies arranged at equal intervals, and the filter assembly has a filtering effect on the airflow. The interior of the filter assembly is connected with a dust removal assembly, and the dust removal assembly has a dust removal and vibration effect on the filter bag 109, so as to clean up the fly ash particles attached to the filter bag 109. The filter assembly includes a filter frame 108 and a filter bag 109 wrapped around the outside of the filter frame 108. The filter frame 108 supports the filter bag 109. The filter frame 108 is internally rotatably connected with a screw rod 110 and a rotating rod 111 that are parallel to the axial direction of the filter frame 108. The screw rod 110 and the rotating rod 111 are arranged parallel to the axial direction of the filter frame 108. The top of the screw rod 110 is connected with a reduction device 112. Since the rotating and flapping speed of the flapping frame 202 is greater than the speed of the lifting frame 201 moving up and down, a reduction device 112 is arranged on the top of the screw rod 110 to reduce the speed of the up and down movement. The input end of the reduction device 112 and the rotating rod 111 are connected through a gear transmission mechanism 113. The rotating rod 111 is externally connected to a rotation driving device. The rotating rod 111 is driven to rotate by the external driving device. The rotating rod 111 drives the screw rod 110 to rotate, and the driving device drives the lifting frame 201 to move up and down by forward and reverse rotations. When in use, the filter bag 109 will intercept the fly ash particles in the flue gas. After long-term use, the surface of the filter bag 109 will be blocked, and the equipment needs to be stopped from time to time to clean the filter bag 109. The following provides a structure that can clean the filter bag 109 without stopping the equipment: the dust removal component includes a lifting frame 201 sleeved on the screw rod 110 and the rotating rod 111, and a beating frame 202 rotatably connected to the outer side of the lifting frame 201, the beating frame 202 can rotate and beat the filter bag 109 from the inside, the lifting frame 201 and the filter frame 108 are coaxially arranged, and a protrusion 203 that contacts the filter bag 109 is provided on one side of the beating frame 202, and the protrusion 203 and the filter bag 109 are in contact. The inner wall of the rotating rod 111 is in contact with each other, the top of the flapping frame 202 is connected with a gear ring 204, the outer wall of the rotating rod 111 is provided with a spline groove, the internal rotation of the lifting frame 201 is connected with a rotating ring 205 spline-connected with the rotating rod 111, the rotating rod 111 drives the driving gear 206 to rotate through the rotating ring 205, the screw rod 110 drives the lifting frame 201 to move up and down, so that the rotating ring 205 performs spline movement up and down on the outer wall of the rotating rod 111, the top of the rotating ring 205 is connected with a driving gear 206 meshing with the gear ring 204, and the bottom of the flapping frame 202 is connected with a fan assembly, the function of the fan assembly is to push the airflow at the bottom upward to accelerate the flow of the internal airflow; The rotating beating of the beating frame 202 alone cannot clean the filter bag 109 well. The following provides a structure that can perform jet cleaning on the filter bag 109: Figure 6 and Figure 7 The lifting frame 201 is internally rotatably connected with a centrifugal blade 207, and the air inlet of the centrifugal blade 207 is connected to the outside of the lifting frame 201. The centrifugal blade 207 can convey the airflow outside the lifting frame 201 into the beating frame 202 by rotating. The top of the lifting frame 201 is rotatably connected with a driven gear 208, and a switching component 209 is connected between the driven gear 208 and the centrifugal blade 207. The driving gear 206 drives the centrifugal blade 207 to rotate through the driven gear 208 and the switching component 209. An annular airflow groove 210 matching the centrifugal blades 207 is provided on the outer ring surface, and a strip flow channel 211 connected to the annular airflow groove 210 is provided on the inner ring surface of the flapping frame 202. A branch flow channel running through the raised portion 203 is provided on the strip flow channel 211. When the centrifugal blades 207 rotate, the airflow is transported into the annular airflow groove 210, and the annular airflow groove 210 and the strip flow channel 211 are connected. Finally, the airflow in the strip flow channel 211 will be ejected from the air holes on the raised portion 203, which has the effect of rotating and flapping while ejecting airflow for cleaning.

[0028] Since the driving device drives the lifting frame 201 to move up and down by forward and reverse rotation, the centrifugal blades 207 will also reverse during the reverse rotation, thereby changing the flow of the internal airflow. The following provides a structure that can deliver the airflow into the lifting frame 201 regardless of forward or reverse rotation: Specifically, refer to Figure 7 The interior of the lifting frame 201 is symmetrically provided with an air flow channel 212 with the screw rod 110 and the rotating rod 111 as a plane. The air flow channel 212 is an air inlet for conveying air flow to the centrifugal blades 207. The bottom of the air flow channel 212 extends out of the lifting frame 201. The centrifugal blades 207 are rotatably connected in the symmetrical air flow channel 212. The blades on the two centrifugal blades 207 are arranged in opposite directions. The centrifugal blades on the two centrifugal blades 207 are arranged in opposite directions, and are arranged in opposite directions for adjusting the rotation of the centrifugal blades 207 according to the rotation direction of the rotating rod 111, so that air flow will enter the lifting frame 201 regardless of forward or reverse rotation; Although one centrifugal blade 207 will work when the rotating rod 111 rotates, the other centrifugal blade 207 will affect the movement of the airflow. The following provides a structure in which only one driving gear 206 drives the centrifugal blade 207 to rotate: Figure 7 and Figure 8 The switching components 209 at the tops of the two centrifugal blades 207 are arranged oppositely up and down, and the switching component 209 includes a first connecting shaft 301 and a second connecting shaft 302, the first connecting shaft 301 and the second connecting shaft 302 do not contact each other, and the first connecting shaft 301 and the second connecting shaft 302 have spline grooves at their facing ends, and the first connecting shaft 301 has a first tooth surface block 303 splined on the outer wall thereof, and the first tooth surface block 303 is splined on the first connecting shaft 301, and the second connecting shaft 302 has a spline baffle 304 splined on the outer wall thereof. The second tooth surface block 305 can be meshed with the first tooth surface block 303, and the first tooth surface block 303 and the second tooth surface block 305 can mesh with each other. The second tooth surface block 305 and the spline baffle 304 are connected by a spring, and the spring pushes the second tooth surface block 305 to move toward the first tooth surface block 303. When one of the first tooth surface blocks 303 and the second tooth surface block 305 are meshed together, the other first tooth surface block 303 and the second tooth surface block 305 are in a disengaged state. The meshed state will transmit the rotation of the top driven gear 208 to the bottom centrifugal blade 207, and the disengaged state will not rotate.

[0029] The connection state between the two switching components 209 needs to be changed back and forth. The following provides a structure that can change the two switching components 209: Specifically, refer to Figure 8A push rod 306 is slidably connected to the lifting frame 201, and a connecting arm 307 rotatably connected to the first tooth surface block 303 is connected to the outer wall of the push rod 306. The connection state between the two switching components 209 is controlled by the up and down movement of the push rod 306; The driven gear 208 at one end delivers the airflow into the annular airflow groove 210, and the airflow in the annular airflow groove 210 flows back to the airflow channel 212 from the driven gear 208 at the other end. The following provides a structure to prevent the airflow from flowing back: Figure 8 A tooth surface portion 308 is provided on the outer wall of the push rod 306, and an adjustment rod 309 is rotatably connected to the inside of the lifting frame 201. A pinion 310 meshing with the tooth surface portion 308 is connected to the outer wall of the adjustment rod 309. When the push rod 306 moves up and down, the meshing connection with the pinion 310 can drive the adjustment rod 309 to rotate. Both ends of the adjustment rod 309 are connected to flaps 311 located in the air flow channel 212. The two flaps 311 are arranged perpendicular to each other. When the adjustment rod 309 rotates, the flaps 311 on both sides will be driven to rotate, thereby controlling the on-off of the air flow channel 212 on one side, thereby realizing the effect of opening the channel on one side and closing the channel on the other side.

[0030] When the rotating rod 111 and the screw rod 110 are reversed, the lifting frame 201 will move downward, and the flapping frame 202 on the outer wall will also flap in the opposite direction, and the fan assembly at the bottom will also be reversed, causing the airflow to move downward. The following provides a structure for reversing the fan assembly: Specifically, refer to Figures 9 to 11 The bottom of the beating frame 202 is connected to a rotating frame 401, and an air inlet chamber 402 is provided inside the rotating frame 401. The top of the air inlet chamber 402 is connected to the air flow channel 212. The external air flow will first enter the air inlet chamber 402 and then move to the air flow channel 212 at the top. A reversing ring plate 403 extending from the rotating frame 401 is rotatably connected inside the air inlet chamber 402. The reversing ring plate 403 controls the direction of the fan assembly by rotating in the air inlet chamber 402. The fan assembly includes a hollow fan blade frame 404 and a fan blade plate 405 located inside the fan blade frame 404. Figures 9 to 11 The top of the blade frame 404 is larger than the bottom. The top of the blade frame 404 is provided with extensions 406 for supporting the blade plate 405. The blade plate 405 rotates in the blade frame 404, and the hinge point of the two is located at the bottom. The reversing ring plate 403 needs to rotate according to the movement of the top rod 306 to change the direction of the fan assembly. The following provides a structure in which the top rod 306 drives the reversing ring plate 403 to rotate: Figures 7 to 10The side wall of the rotating frame 401 is provided with a reversing slide 407 extending to the air inlet cavity 402. The reversing slide 407 is used for the back and forth movement of the air duct 408. The top of the fan blade frame 404 is connected to the air duct 408 located in the air inlet cavity 402. Fig.10 When the fan assembly rotates, part of the upward airflow will be guided by the fan blade plate 405 to move to the top of the fan blade frame 404, and then enter the air inlet chamber 402 through the air duct 408. The air duct 408 and the reversing ring plate 403 are rotatably connected. The fan blade frame 404 is provided with a first sliding groove 409 on the side close to the air duct 408. The first sliding groove 409 is in a long strip shape. The outer wall of the rotating frame 401 is connected with a first boss 410 extending into the first sliding groove 409. When the reversing ring plate 403 drives the fan blade frame 404 to rotate through the air duct 408, the first boss 410 will slide in the first sliding groove 409 to adapt to the rotation of the fan blade frame 404.

[0031] Specifically, refer to Figures 7 to 10 The outer wall bottom of the push rod 306 is connected with an annular frame 411, and a reversing bracket 412 is rotatably connected to the outer ring surface of the annular frame 411. The reversing bracket 412 can rotate along the annular frame 411. A second sliding groove 413 is provided at the bottom of the inner ring surface of the reversing ring plate 403. The outer ring surface of the reversing bracket 412 is connected with a second boss 414 located in the second sliding groove 413. The reversing ring plate 403 can be driven to rotate by the up and down movement of the reversing bracket 412. When the rotating frame 401 drives the internal reversing ring plate 403 to rotate, the reversing ring plate 403 will drive the reversing bracket 412 to rotate on the outer wall of the annular frame 411; The direction of the fan assembly needs to be adjusted according to the rotation of the flap frame 202 to ensure that the airflow inside the filter assembly always flows upward. The following provides a structure for changing the direction of the fan blades: Figures 9 to 11 The bottom of the fan blade plate 405 is rotatably connected to the fan blade frame 404, and the internal rotation of the air duct 408 is connected to the trigger tube 415. The end of the trigger tube 415 located inside the fan blade frame 404 is connected to a connecting frame 416. The trigger tube 415 rotates in the air duct 408, which will drive the connecting frames 416 and the pressure rod 419 at both ends to rotate. The end of the connecting frame 416 away from the trigger tube 415 is rotatably connected to a rotating table 417. A through groove is opened inside the rotating table 417, which is slidably connected to the outer wall of one side of the fan blade plate 405. When the connecting frame 416 drives the rotating table 417 to rotate, the rotating table 417 will slide on one side of the fan blade plate 405, thereby pushing the fan blade plate 405 toward the other end, changing the position of the fan blade plate 405 in the fan blade frame 404, thereby changing the flow direction of the airflow, and changing the action reference Fig.11The inner bottom end of the rotating frame 401 is provided with a strip groove 418, and one end of the trigger tube 415 located in the air inlet chamber 402 is connected to a pressure rod 419 connected to the side walls of the strip groove 418 at both ends. When the reversing ring plate 403 rotates, the top of the fan blade frame 404 is driven to move through the air duct 408, and the pressure rod 419 at one end of the air duct 408 comes into contact with the side wall of the strip groove 418, thereby driving the connecting frame 416 to rotate through the trigger tube 415. After the connecting frame 416 rotates, the position of the fan blade plate 405 is adjusted. Fig.11 .

[0032] After the top rod 306 moves, it needs to be fixed to prevent displacement: Figure 6 and Figure 7 Specifically, cavities 501 are provided at both ends of the push rod 306, and a trigger pressure block 502 is slidably connected in the cavity 501. The trigger pressure block 502 and the cavity 501 are connected by a spring. The spring is used to push the trigger pressure block 502 out of the cavity 501, and a limiting structure is provided at the end to prevent it from escaping. When squeezed, the trigger pressure block 502 will be squeezed back into the cavity 501. An oblique sliding groove 503 is provided on the side wall of the trigger pressure block 502, and a positioning block 504 is slidably connected to the oblique sliding groove 503. When the trigger pressure block 502 is squeezed back into the cavity 501, the positioning block 504 will be pulled back into the cavity 501 through the oblique sliding groove 503. A hole through which the positioning block 504 passes is provided on the side wall of the push rod 306, and a positioning platform 505 is connected to the bottom of the lifting frame 201. A positioning hole 506 for inserting the positioning block 504 is provided inside the positioning platform 505 and the lifting frame 201. When the spring pushes the trigger pressure block 502 out of the cavity 501, the trigger pressure block 502 will drive the positioning block 504 to move toward the side away from the axis of the cavity 501 through the oblique slide groove 503. If it is exactly corresponding to the positioning hole 506, it will be inserted into the positioning hole 506 to fix the push rod 306. It should be noted that only one of the positioning blocks 504 at both ends will be inserted into the positioning hole 506. Specifically, when the lifting frame 201 moves to the top, the trigger pressure block 502 on the top of the top rod 306 will first come into contact with the top bracket 114, and the trigger pressure block 502 will be pressed back into the cavity 501. At the same time, the top positioning block 504 will be pulled out of the positioning hole 506, and then the top rod 306 will come into contact with the top bracket 114, and then be pushed to move downward. When moving to the bottom, the bottom positioning block 504 will be aligned with the positioning hole 506 on the positioning platform 505, and then inserted into it. At the same time, the bottom will drive the reversing bracket 412 to move downward through the annular frame 411, and drive the reversing ring plate 403 to rotate. The top will drive one switching component 209 to disconnect and the other switching component 209 to close through the connecting arms 307 on both sides, thereby completing the switching between the two centrifugal blades 207.

[0033] When the trigger block 502 is pressed into the cavity 501 and the push rod 306 is not pressed down, the push rod 306 will be displaced. The following provides a structure for pre-fixing the push rod 306: Figure 7 The inner ring surface of the positioning platform 505 is connected with a ball positioning assembly 507. The ball positioning assembly 507 is a structure with a ball at one end and a spring connected to the other side. It is preferably a threaded spring roller and is installed in the positioning platform 505 through threads. The outer wall of the ejector rod 306 is provided with a pre-fixing hole 508 that matches the ball positioning assembly 507. The ejector rod 306 is positioned through the pre-fixing hole 508. refer to Figure 4 The top of the screw rod 110 and the rotating rod 111 are connected with a top bracket 114, and the top bracket 114 is fixed on the top plate 106. The top bracket 114 supports the rotating rod 111 and the screw rod 110, and also has the function of squeezing the trigger pressure block 502.

[0034] After the fly ash is cleaned off the filter bag 109, the fly ash may be adsorbed on the filter bag 109 again. The following is a structure for guiding the airflow: Figure 4 and Fig.12 , specifically, refer to Fig.12The bottom of the filter frame 108 is connected to a bottom plate 601, and an upper dust frame 602 is connected to the outside of the bottom plate 601. The upper dust frame 602 and the lower dust frame 603 are fixed to the bottom of the filter frame 108 through the bottom plate 601. The upper dust frame 602 and the lower dust frame 603 are hemispherical. The bottom of the upper dust frame 602 is connected to the lower dust frame 603. The inside of the bottom plate 601 is rotatably connected to a centrifugal disk 604. The top of the centrifugal disk 604 is provided with an arc blade, which has the function of guiding the airflow and can also remove the flying dust on it. The ash is thrown to the lower dust frame 603, and the fly ash particles will accumulate on the inner ring surface of the lower dust frame 603. As the dust accumulates, the weight increases, and the fly ash falls on the fly ash pile at the bottom. The top of the centrifugal disk 604 is connected to a driven gear 208, and the bottom of the rotating rod 111 is connected to a one-way gear 605 meshing with the driven gear 208. The one-way gear 605 is a mechanical structure that can only rotate in one direction, usually called a "one-way clutch" or "one-way bearing", which allows the shaft to rotate freely in one direction and is locked in the other direction. Or drive gear to rotate. This type of device is commonly found in mechanical equipment that needs to prevent reversal or needs to transmit power in a specific direction. This is a mature device and will not be described in detail here. Preferably, when the lifting frame 201 moves downward, the centrifugal disk 604 at the bottom will rotate. When the lifting frame 201 moves downward, since the top area of ​​the filter bag 109 has been cleaned and the bottom area has not been cleaned, the airflow will move upward, affecting the filtration of the newly entered flue gas. At this time, the downward airflow will well guide the cleaned fly ash particles downward. The airflow flowing out from the bottom of the lower dust frame 603 will move upward and then go out of the filter bag 109. Although the bottom dust will be disturbed during the process, since it moves upward, it will not cause large-scale disturbance. After moving to the top, it will also be filtered by the filter bag 109. It should be noted that when the one-way gear 605 does not drive the driven gear 208 to rotate, the centrifugal disk 604 will reverse due to the internal airflow, but due to the lack of a direct driving source, the rotation speed will not be too fast, so it will not affect normal use.

[0035] The multiple rotating rods 111 all require a driving structure. The following provides a structure for keeping the multiple rotating rods 111 rotating synchronously: Figure 2 Specifically, the tops of the plurality of rotating rods 111 are connected via a chain transmission mechanism 115, and a driving motor 116 is connected to the top of the top plate 106. The driving motor 116 drives one of the rotating rods 111 to rotate via the chain transmission mechanism 115. All the rotating rods 111 are then connected via a gear transmission mechanism 113, and all the rotating rods 111 are driven by a driving motor 116 to rotate synchronously. One of the rotating rods 111 and the driving motor 116 are connected via a chain transmission mechanism 115.

[0036] A dust removal method for a garbage incineration fly ash storage bin: S1. Air delivery: The flue gas containing fly ash is transported into the ash storage tank 101 through the air inlet pipe 103. After entering, the flue gas will hit the fly ash baffle 104, and most of the dust and gas in the flue gas will be separated, so that the dust particles fall to the bottom of the ash storage tank 101. After being blocked by the fly ash baffle 104, the flue gas moves from the top of the fly ash baffle 104 to the filter assembly, and moves from the top to the filter assembly to avoid the flue gas flowing close to the fly ash pile, causing the fly ash to be swung up; S2, shaking cleaning: start the driving motor 116, the driving motor 116 drives the rotating rod 111 to rotate through the chain transmission mechanism 115, and the rotating rod 111 drives the beating frame 202 to rotate around the lifting frame 201 when rotating, and the protrusion 203 on the beating frame 202 beats the inner wall of the filter bag 109, and the filter bag 109 is shaken from the inside, so that the dust attached to the filter bag 109 is beaten off, and at the same time, the internal centrifugal blades 207 rotate to spray the internal airflow from the holes on the protrusion 203, so as to enhance the cleaning effect on the filter bag 109; S3, movement: the rotating rod 111 drives the screw rod 110 to rotate through the gear transmission mechanism 113, so that the dust removal component moves up and down in the filter component, and the up and down movement increases the cleaning area, and plays a cleaning role on the entire filter bag 109. When the dust removal component rotates, it drives the fan component at the bottom to rotate synchronously, so that the airflow in the filter component moves upward, increasing the flow of the internal airflow; S4, guiding airflow: when the dust removal assembly moves downward, the centrifugal disk 604 at the bottom rotates to guide the airflow outside the filter assembly toward the upper dust rack 602. When dust particles fall on the centrifugal disk 604, they are affected by centrifugal force and are thrown onto the lower dust rack 603. Finally, they fall onto the dust pile at the bottom due to gravity. S5. Discharge: The gas passing through the filter assembly will be discharged from the gas outlet pipe 107, and the dust particles will be discharged from the ash discharge port at the bottom of the ash storage tank 101.
