Description

Technical Field

[0001] This invention relates to the technical field of electrostatic precipitator-baghouse composite dust collectors, specifically an energy-saving electrostatic precipitator-baghouse composite dust collector for pollution prevention. Background Technology

[0002] Electrostatic precipitator-baghouse hybrid dust collectors, as important specialized environmental protection equipment, are widely used in flue gas treatment in industries such as coal-fired power plants, steel, building materials, and chemicals. They play a crucial role in controlling air pollution and reducing industrial dust emissions. Their typical structure employs a collaborative "front-electrostatic, rear-bag" working mode: dust-laden flue gas first enters the front-end electrostatic precipitator zone, where a high-voltage electrostatic field charges the dust particles, with most coarse dust particles being directly captured by the anode plates. Subsequently, the charged fine dust particles enter the rear-end baghouse zone. Due to the repulsion of like charges, the dust forms a loose, breathable dust cake layer on the filter bag surface, significantly reducing operating resistance and extending the cleaning cycle, achieving highly efficient purification and demonstrating significant advantages in deep air pollution control.

[0003] However, in actual operation, especially when dealing with flue gas under humid conditions, existing electrostatic precipitator-baghouse hybrid dust collectors, as key environmental protection equipment, have the following technical problems: First, after being captured by the anode plate and detached by rapping, the damp dust easily adheres to and accumulates on the upper edge of the ash hopper in the electric field. Over time, the accumulated dust gradually submerges the anode plate and cathode wires at the bottom. Since damp dust is generally conductive, when the dust accumulates to a certain height, a conductive path forms between the anode and cathode through the accumulated dust, resulting in a "dust short circuit." This causes the electric field to completely fail, severely impacting the effectiveness of air pollution control. Traditional electromagnetic vibrators can only perform conventional rapping of the plates and cannot effectively remove the layer of damp, caked dust that has accumulated on the upper edge of the ash hopper.

[0004] Secondly, during the transition of flue gas from the electrostatic precipitator zone to the bag filter zone, the airflow needs to pass through a baffle plate placed between the two. In the existing structure, the airflow usually enters the bag filter zone through a channel at the bottom of the baffle plate, resulting in excessively high local wind speeds in this area. The dust carried by the high-speed airflow directly washes over the bottom of the filter bags, causing accelerated wear on the bottom of the filter bags, significantly reducing the service life of the filter bags, and increasing the operation and maintenance costs of environmental protection equipment.

[0005] Therefore, an energy-saving electrostatic precipitator-baghouse composite dust collector for pollution prevention is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide an energy-saving electrostatic precipitator-baghouse composite dust collector for pollution prevention, in order to solve the problems in the prior art where damp dust easily accumulates on the upper edge of the ash hopper in the electrostatic precipitator zone, causing "ash short circuit" between the anode and cathode and electric field failure, as well as the uneven airflow distribution when flue gas enters the baghouse dust collector zone from the electrostatic precipitator zone, and the high-speed airflow easily causing erosion and wear on the bottom of the filter bag, thus reducing the service life of the filter bag.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving electrostatic precipitator / baghouse composite dust collector for pollution prevention, comprising a shell, an electrostatic precipitator hopper, an electrostatic precipitator zone, a baghouse precipitator zone, a partition, an electromagnetic vibrator, a disturbance component, a stirring component, and a flow equalization component; the electrostatic precipitator zone includes an anode plate and a cathode wire fixedly connected to the top of the shell; the electrostatic precipitator hopper is fixedly connected to the bottom of the shell, the electrostatic precipitator zone is located above the electrostatic precipitator hopper, the baghouse precipitator zone is located on one side of the electrostatic precipitator zone, the partition is fixedly connected to the shell and located between the electrostatic precipitator zone and the baghouse precipitator zone, and the electromagnetic vibrator is disposed at the top of the shell. The electromagnetic vibrator is positioned above the anode plate and is used to apply a rapping force to the anode plate. The disturbance component is located above the dust hopper in the electric zone. The agitator is vertically movable inside the anode plate. The flow equalization component is located on the partition plate. During the vibration process of the electromagnetic vibrator, the disturbance component is rotated, which disturbs the dust accumulated above the dust hopper in segments, disrupting its conductive continuity. The vibration generated by the electromagnetic vibrator is transmitted to the disturbance component through the agitator, causing it to swing. The reciprocating motion of the electromagnetic vibrator causes the flow equalization component to swing, disturbing the airflow to the bag filter area. The swinging flow equalization component generates an impact force that reacts on the anode plate.

[0008] Preferably, the disturbance component includes a guide rail groove, a floating rod, insulating fan blades, a gear, and a driving component; the guide rail groove is fixedly connected to the inner side of the housing, the floating rod slides with the guide rail groove, the floating rod has two sets respectively located on both sides of the anode plate, the anode plate is perpendicular to the floating rod, multiple sets of insulating fan blades are equidistantly arranged and rotatably connected to the floating rod, each set of insulating fan blades is located between every two sets of anode plates, the gear is fixedly connected to one side of the center of the insulating fan blade, and the driving component moves back and forth with the electromagnetic vibrator to drive the insulating fan blades to instantly accelerate and rotate and switch directions; when the flue gas enters the electrostatic precipitator zone, the airflow will push the insulating fan blades to rotate along the floating rod, thereby disturbing the dust in the channel between the ash hopper above the electrostatic precipitator zone and the anode plate.

[0009] Preferably, a pull rope is also provided between the floating rods. There are two sets of pull ropes. The two ends of the pull ropes pass through the two ends of the floating rods and are fixedly connected to the shell. The pull ropes and the floating rods form a rectangular structure surrounding the bottom of the anode plate. The pull ropes taut the floating rods and suspend them between the upper edge of the ash hopper in the electrostatic precipitator and the anode plate. When the flue gas enters the electrostatic precipitator zone, the airflow causes the floating rods to sway slightly up and down along the guide rail groove.

[0010] Preferably, the driving component includes a driving rod and a toothed plate; the driving rod is slidably connected to the inside of the anode plate and located near both sides of the anode plate, the top of the driving rod is fixedly connected to the output end of the electromagnetic vibrator, and the toothed plate is fixedly connected to the bottom end of the driving rod; when the electromagnetic vibrator is descending and vibrating, it will drive the driving rod to descend rapidly so that the toothed plate passes through the gear position, and at the moment the toothed plate contacts the gear, it will drive the gear and the insulating fan blades to rotate rapidly, thereby increasing the centrifugal force of the insulating fan blades to quickly shake off the dust attached to them. When the electromagnetic vibrator rises and drives the toothed plate to pass through the gear, it will cause the insulating fan blades to instantly change their rotation direction, thereby effectively promoting the dust shaking effect of the insulating fan blades themselves. At the same time, the alternating vibration mode of the electromagnetic vibrator can form an alternating rotation of the insulating fan blades, enhancing the disturbance effect on the dust.

[0011] Preferably, the actuating assembly includes a central transmission rod and a paddle block; the central transmission rod is provided in two sets, respectively located in the middle of the two outer sets of anode plates and slidably connected thereto; the top of the central transmission rod is fixedly connected to the output end of the electromagnetic vibrator; the paddle block is arranged in an isosceles trapezoidal shape and is located in the middle of the pull rope; during the vibration of the electromagnetic vibrator, the electromagnetic vibrator located in the middle above the anode plate at the edge position will drive the transmission rod to move up and down, thereby driving the paddle block to actuate the middle of the pull rope, the pull rope will generate ripples and transmit the wave power to the floating rod, causing the floating rod to move up and down significantly along the guide rail groove.

[0012] Preferably, the flow equalization component includes a dispersion channel, blades, an arc-shaped telescopic rod, and a pushing component; the dispersion channel is opened on the partition plate, the blades are rotatably connected to the top of the dispersion channel, the arc-shaped telescopic rod is telescopically connected between the blades and the partition plate, and the arc of the telescopic rod extends to form a complete circle at both ends, with its center being the same as the axis at the junction of the blades and the partition plate; the dispersion channel opened on the partition plate allows flue gas to enter the bag filter area simultaneously from the dispersion channel and the bottom channel of the partition plate when the flue gas passes through the partition plate from the electrostatic precipitator area, thereby preventing the flue gas from being too concentrated and passing through the bottom channel of the partition plate, causing wear to the filter bag.

[0013] Preferably, the plate blade is pushed by the arc-shaped telescopic rod to abut against the sides of all anode plates, and the plate blade is made of insulating material; wherein the arc-shaped telescopic rod is provided with a spring, and the plate blade always remains in contact with the outer side of the anode plate.

[0014] Preferably, the pushing component includes a shrinking shell, an inclined push block, and a pushing spring; the shrinking shell is fixedly connected to one of the drive rods, the inclined push block is slidably connected to the shrinking shell, and the pushing spring is fixedly connected between the shrinking shell and the inclined push block. When the output end of the electromagnetic vibrator at the top of the shrinking shell shrinks, the inclined push block is above the plate blade; when the output end of the electromagnetic vibrator above the anode plate in the middle position near the partition plate descends and vibrates, it will drive the shrinking shell to move down quickly through the drive rod below it, thereby driving the bottom parallel surface of the inclined push block to quickly pass the plate blade. The plate blade will be pushed towards the partition plate by the thrust. After the inclined push block passes, the plate blade will be pushed by the spring in the arc-shaped telescopic rod, quickly reset and impact the side of the anode plate, thereby playing a vibration compensation role for the anode plate and enhancing the vibration effect on the anode plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. Preventing "dust short circuits" and ensuring stable operation of the electrostatic precipitator: By setting up disturbance components (insulated fan blades, floating rods, etc.), the flue gas flow drives the insulated fan blades to rotate continuously, disturbing the damp dust accumulated above the ash hopper in the electrostatic precipitator in segments, disrupting its conductive continuity; at the same time, the electromagnetic vibrator uses a drive component to instantly accelerate and reverse the insulated fan blades, and works with the actuation component to drive the floating rod to swing up and down, increasing the disturbance area of ​​the insulated fan blades to effectively remove the attached dust, preventing dust accumulation from causing short circuits between the anode and cathode, and ensuring long-term stable operation of the electrostatic precipitator area.

[0016] 2. Optimize airflow distribution and reduce filter bag wear: Dispersing channels are opened on the partition and flow equalization components (plate blades, arc-shaped telescopic rods, etc.) are set up to form multiple airflows when the flue gas enters the bag filter from the electrostatic precipitator zone, avoiding concentrated airflow from washing the bottom of the filter bag; at the same time, the plate blades oscillate periodically under the drive of the electromagnetic vibrator, further disturbing and dispersing the airflow path, so that the flue gas is evenly distributed to each filter bag, significantly reducing the wear of the filter bag by local high-speed airflow and extending the service life of the filter bag.

[0017] 3. Enhanced vibration effect and improved dust removal efficiency: The electromagnetic vibrator reciprocates, and the drive component and the agitator drive the disturbance component to rotate, swing and vibrate, which strengthens the cleaning of dust accumulated at the bottom of the electrode plate and the upper edge of the ash hopper; at the same time, the blades in the flow equalization component hit the side of the anode plate when resetting, forming vibration compensation, which helps the dust on the surface of the anode plate to fall off, improves the overall dust removal efficiency, reduces energy consumption and thus achieves the overall energy saving of the device.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1 to 8 This invention provides an energy-saving electrostatic precipitator / baghouse composite dust collector for pollution prevention, the technical solution of which is as follows: Reference Figure 1 and Figure 2An energy-saving electrostatic precipitator / baghouse hybrid dust collector for pollution prevention is disclosed. The device includes a housing 1, an electrostatic precipitator hopper 11, an electrostatic precipitator zone 2, a baghouse dust collector zone 3, a partition 4, an electromagnetic vibrator 5, a disturbance component 6, a shifting component 7, and a flow equalization component 8. The electrostatic precipitator zone 2 includes an anode plate 21 and a cathode wire 22 fixedly connected to the top of the housing 1. The electrostatic precipitator hopper 11 is fixedly connected to the bottom of the housing 1, the electrostatic precipitator zone 2 is located above the hopper 11, the baghouse dust collector zone 3 is located on one side of the electrostatic precipitator zone 2, the partition 4 is fixedly connected to the housing 1 and located between the electrostatic precipitator zone 2 and the baghouse dust collector zone 3, the electromagnetic vibrator 5 is located above the anode plate 21 and fixedly connected to the top of the housing 1, and the disturbance component... The agitator 6 is positioned above the ash hopper 11 in the electrostatic precipitator zone. The agitator 7 is slidably connected to the inside of the anode plate 21, and the flow equalization component 8 is positioned on the partition plate 4. During the vibration process of the electromagnetic vibrator 5, the disturbance component 6 rotates, causing segmented disturbance of the dust accumulated above the ash hopper 11 in the electrostatic precipitator zone, disrupting its conductive continuity. The vibration generated by the electromagnetic vibrator 5 is transmitted to the disturbance component 6 through the agitator 7, causing it to oscillate. The reciprocating motion of the electromagnetic vibrator 5 causes the flow equalization component 8 to oscillate, disrupting the airflow to the bag filter zone 3. The oscillating flow equalization component 8 generates an impact force that reacts on the anode plate 21. During operation, the flue gas containing dust enters the electrostatic precipitator zone 2 from the left side of the housing 1, first passing through the anode plate 21 in the electrostatic precipitator zone 2. After adsorption, the flue gas enters the bag filter area 3 for filtration and is finally discharged from the right outlet pipe of the bag filter. When the flue gas passes through the electrostatic precipitator area 2, the airflow will cause the agitator component 6 to rotate, thereby agitating the dust between the bottom of the anode plate 21 and the upper edge of the ash hopper 11, preventing dust from accumulating along the upper edge of the ash hopper 11 and causing a short circuit between the anode and cathode. At the same time, the output end of the electromagnetic vibrator 5 will also momentarily increase the rotation speed of the agitator component 6 during the descent to vibrate the anode plate 21, shaking off the dust attached to the agitator component 6. After the output end of the electromagnetic vibrator 5 rises, it will drive the agitator component 6 to stop suddenly and then reverse, accelerating the falling of its own dust. During the upward and downward movement of the output end of the vibrator 5, the agitator component 7 will drive the disturbance component 6 to swing up and down, thereby further enhancing the disturbance effect of the disturbance component 6 on the dust on the upper edge of the dust hopper 11 in the electrostatic precipitator zone. When the flue gas enters the bag filter zone 3 from the electrostatic precipitator zone 2, it will pass through the flow equalization component 8. The flow equalization component 8 can increase the flue gas channel, so that the flue gas enters the bag filter zone 3 more evenly and disperses, preventing the flue gas from being too concentrated and causing wear to the bottom of the filter bag. At the same time, the up and down movement of the electromagnetic vibrator 5 will also push the flow equalization component 8 to swing and compress before releasing and striking the side of the anode plate 21, which will enhance the vibration effect and disperse and disturb the airflow path, so that the flue gas is more evenly distributed to every part of the filter bag.

[0022] Reference Figures 3 to 5The disturbance component 6 includes a guide rail groove 61, a floating rod 62, an insulating fan blade 63, a gear 64, and a drive component 65. The guide rail groove 61 is fixedly connected to the inner side of the housing 1, and the floating rod 62 slides with the guide rail groove 61. The floating rod 62 has two sets located on both sides of the anode plate 21. The anode plate 21 is perpendicular to the floating rod 62. Multiple sets of insulating fan blades 63 are equidistantly arranged and rotatably connected to the floating rod 62. Each set of insulating fan blades 63 is located between every two sets of anode plates 21. The gear 64 is fixedly connected to one side of the center of the insulating fan blade 63. The drive component 65 moves back and forth with the electromagnetic vibrator 5 to drive the insulating fan blades 63 to instantly accelerate and rotate and switch directions. When the flue gas enters the electrostatic precipitator zone 2, the airflow will push the insulating fan blades 63 to rotate along the floating rod 62, thereby disturbing the dust in the channel between the ash hopper 11 and the anode plate 21, interrupting the continuity of dust, and preventing the accumulation of damp dust from causing a short circuit between the anode plate 21 and the cathode wire 22.

[0023] Reference Figure 3 A pull rope 621 is also provided between the floating rods 62. There are two sets of pull ropes 621. The two ends of the pull rope 621 pass through the two ends of the floating rods 62 and are fixedly connected to the housing 1. The pull rope 621 and the floating rods 62 form a rectangular structure surrounding the bottom of the anode plate 21. The pull rope 621 tauts the floating rods 62 and suspends them between the upper edge of the ash hopper 11 in the electrostatic precipitator and the anode plate 21. When the flue gas enters the electrostatic precipitator zone 2, the airflow causes the floating rods 62 to sway slightly up and down along the guide rail groove 61, which in turn promotes the dust disturbance effect of the insulated fan blades 63.

[0024] Reference Figure 4 and Figure 5 The driving component 65 includes a driving rod 651 and a toothed plate 652. The driving rod 651 is slidably connected to the inside of the anode plate 21 and is located near both sides of the anode plate 21. The top of the driving rod 651 is fixedly connected to the output end of the electromagnetic vibrator 5, and the toothed plate 652 is fixedly connected to the bottom end of the driving rod 651. The electromagnetic vibrators 5 above each group of anode plates 21 operate in an alternating vibration mode. When the output ends of the electromagnetic vibrators 5 above the first, third, fifth, and seventh groups of anode plates 21 extend and vibrate, the output ends of the electromagnetic vibrators 5 above the second, fourth, and sixth groups of anode plates 21 are in an upward and retracted state. Furthermore, when the electromagnetic vibrators 5 descend... During the vibration process, the drive rod 651 will descend rapidly, causing the toothed plate 652 to pass the position of the gear 64. At the moment the toothed plate 652 contacts the gear 64, the gear 64 and the insulating fan blade 63 will rotate rapidly, thereby increasing the centrifugal force of the insulating fan blade 63 to quickly shake off the dust attached to it. When the electromagnetic vibrator 5 rises and causes the toothed plate 652 to pass the gear 64, it will cause the insulating fan blade 63 to instantly change its rotation direction, thereby effectively promoting the dust shaking effect of the insulating fan blade 63 itself. At the same time, the alternating vibration mode of the electromagnetic vibrator 5 can form an alternating rotation of the insulating fan blade 63, enhancing the disturbance effect on the dust.

[0025] Reference Figure 4 and Figure 6 The actuating assembly 7 includes a central transmission rod 71 and a lever 72. The central transmission rod 71 has two sets, which are located in the middle of the two outer anode plates 21 and are slidably connected to them. The top of the central transmission rod 71 is fixedly connected to the output end of the electromagnetic vibrator 5. The lever 72 is arranged in an isosceles trapezoidal shape and is located in the middle of the pull rope 621. During the vibration of the electromagnetic vibrator 5, the electromagnetic vibrator 5 located in the middle of the anode plate 21 above the edge position will drive the transmission rod to move up and down, thereby driving the lever 72 to actuate the middle of the pull rope 621. The pull rope 621 will generate fluctuations and transmit the wave power to the floating rod 62, which will drive the floating rod 62 to move up and down significantly along the guide rail groove 61. This can increase the disturbance area of ​​the insulating fan blade 63 and further promote the disturbance effect of the dust between the ash hopper 11 and the anode plate 21 in the rotating insulating fan blade 63 electric area, preventing the occurrence of sticky dust that is difficult to clean.

[0026] Reference Figure 7 and Figure 8 The flow equalization component 8 includes a dispersion channel 81, a blade 82, an arc-shaped telescopic rod 83, and a pusher 84. The dispersion channel 81 is opened on the partition 4. The blade 82 is rotatably connected to the top of the dispersion channel 81. The arc-shaped telescopic rod 83 is telescopically connected between the blade 82 and the partition 4, and has a spring inside. The arc of the arc-shaped telescopic rod 83 extends to intersect at both ends to form a complete circle. The arc shape of the arc-shaped telescopic rod 83 can adapt to the rotation trajectory of the blade 82, and its center is the same as the center of the axis where the blade 82 and the partition 4 are connected. The dispersion channel 81 opened on the partition 4 allows the flue gas to enter the bag filter area 3 simultaneously from the dispersion channel 81 and the bottom channel of the partition 4 when it passes through the partition 4 from the electrostatic precipitator area 2. This prevents the flue gas from being too concentrated and passing through the bottom channel of the partition 4, thus preventing wear on the filter bags.

[0027] Reference Figure 8 The blade 82 is pushed by the arc-shaped telescopic rod 83 to abut against the sides of all anode plates 21, and the blade 82 is made of insulating material; the arc-shaped telescopic rod 83 is equipped with a spring, and the blade 82 always remains in contact with the outside of the anode plate 21.

[0028] Reference Figure 8The pushing component 84 includes a retractable shell 841, a slanted push block 842, and a push spring 843. The retractable shell 841 is fixedly connected to one of the drive rods 651. The slanted push block 842 is slidably connected to the retractable shell 841. The push spring 843 is fixedly connected between the retractable shell 841 and the slanted push block 842. When the output end of the electromagnetic vibrator 5 at the top of the retractable shell 841 retracts, the slanted push block 842 is above the plate blade 82. When the output end of the electromagnetic vibrator 5 above the anode plate 21 near the partition plate 4 in the middle position descends and vibrates, it will drive the retractable shell 841 to move down quickly through the drive rod 651 below it, thereby driving the bottom parallel surface of the slanted push block 842 to quickly pass through the plate blade 82. The plate blade 82 will be pushed towards the partition plate. As the inclined push block 842 swings closer in four directions, it is pushed by the spring inside the arc-shaped telescopic rod 83 after passing the rear plate blade 82, quickly resetting and impacting the side of the anode plate 21. This provides vibration compensation for the anode plate 21, enhances the vibration effect on the anode plate 21, and accelerates the dust removal effect on the anode plate 21. During the rapid swinging process, the plate blade 82 can effectively disperse and disrupt the airflow path, making the flue gas more evenly distributed to every part of the bag. When the inclined push block 842 retracts and rises with the electromagnetic vibrator 5, it will gradually retract into the shrink shell 841 due to the gradual contact between the inclined surface and the outer side of the plate blade 82. After passing the plate blade 82, it will automatically pop out, thus realizing the periodic vibration compensation of the anode plate 21 by the plate blade 82.

[0029] Working Principle: When the device is working, dust-laden flue gas first enters the electrostatic precipitator zone 2 from the left side of the casing 1. Under the action of the electric field, the dust is adsorbed by the anode plate 21, and then the airflow enters the bag filter zone 3, is filtered by the filter bags, and is discharged from the right outlet. During this process, the flue gas airflow itself drives the insulating fan blades 63 in the disturbance component 6 to rotate continuously along the floating rod 62, disturbing the dust between the top of the ash hopper 11 and the bottom of the anode plate 21, disrupting the conductive continuity of the dust layer, and preventing short circuits between the anode and cathode due to the accumulation of damp dust. At the same time, the pull rope 621 suspends the floating rod 62 between the upper edge of the ash hopper and the anode plate 21. The airflow causes the floating rod 62 to sway slightly up and down along the guide rail groove 61, further enhancing the disturbance effect of the insulating fan blades 63 on the dust.

[0030] The electromagnetic vibrator 5 operates in an alternating pattern of "partial vibration and partial retraction," creating an alternating speed-up rotation of the insulating fan blades 63, thus enhancing the dust agitation effect. When the vibrator output end descends to vibrate the anode plate 21, the drive rod 651 drives the toothed plate 652 to quickly pass through the gear 64, driving the insulating fan blades 63 to instantly accelerate and rotate, using centrifugal force to shake off the dust adhering to them. When the vibrator output end rises, the toothed plate 652 reverses direction and passes through the gear 64, causing the insulating fan blades 63 to instantly reverse direction, further promoting dust dissipation. At the same time, the electromagnetic vibrator 5, located in the middle of the edge anode plate 21, drives the lever 72 to move up and down through the central transmission rod 71. The lever 72 repeatedly moves the middle of the pull rope 621, causing the pull rope 621 to fluctuate and transmit the vibration to the floating rod 62, causing the floating rod 62 to move significantly up and down along the guide rail groove 61, thereby expanding the agitation range of the insulating fan blades 63 and effectively dealing with highly adhesive dust.

[0031] As the flue gas transitions from the electrostatic precipitator zone 2 to the bag filter zone 3, the dispersion channel 81 on the baffle 4, together with the bottom channel, forms multiple airflow paths, preventing the flue gas from concentrating at the bottom and causing wear on the filter bags. The electromagnetic vibrator 5, located in the middle and close to the baffle 4, moves downwards during vibration, driving the shrink shell 841 to move rapidly downwards via the drive rod 651. The inclined push block 842 passes parallel to the blade 82, pushing it to swing towards the baffle 4. After the inclined push block 842 passes, the blade 82 quickly resets under the action of the spring within the arc-shaped telescopic rod 83, colliding with the side of the anode plate 21, thus compensating for the vibration on the anode plate 21 and accelerating the shedding of residual dust from it. Simultaneously, the rapid swinging of the blade 82 also disrupts and disperses the airflow path, making the flue gas distribution in the bag filter zone 3 more uniform, ensuring that the airflow is evenly distributed to every filter bag, thereby improving dust removal efficiency while achieving energy-saving operation.
