Description

Technical Field

[0001] The present application relates to the technical field of uniform gas distribution in a dust collector, and in particular to a flue gas dust collector with an adjustable distribution plate. Background Art

[0002] At present, a large amount of high-temperature, corrosive dusty gas is often produced in the production and processing of thermal power, chemical industry, metallurgy and other industries. These gases will seriously pollute the surrounding environment and endanger the life safety of workers, and also reduce work production efficiency. The dust discharged into the atmosphere will float for a long time, which will reduce atmospheric visibility, cause soot pollution, and harm human health. Therefore, dust removal in industrial production is not only to meet emission standards and environmental issues, but also to protect people's health and safety.

[0003] In current dust removal equipment, the airflow distribution plate is an important part. Its main function is to divide the large amount of turbulence in front of the distribution plate, so that the airflow fills the space and tends to be uniform. The airflow distribution plate is a throttling porous plate. When the gas contacts the throttling plate, the gas flow rate in the middle is larger, while the gas in the front is blocked, causing the gas to generate static pressure energy, causing the gas to diffuse to the surroundings, so that the gas tends to be evenly distributed in the bell mouth space. A blade guide plate can be set in the bell mouth to further improve the gas uniformity.

[0004] In the above technology, as the cross-section of the bell mouth gradually increases, part of the airflow will tend to gradually diffuse in the direction of less resistance. Therefore, the gas in the middle of the bell mouth will decrease, resulting in a larger gas flow near the inner wall of the bell mouth. In addition, the guide plate used in the project can only be welded on the airflow distribution plate at the initial setting angle, and the guide plate angle cannot be changed according to different airflow conditions, so that the effects produced at different airflow velocities will be different, resulting in unsatisfactory airflow distribution effect in some cases, so improvements are made to this. Summary of the invention

[0005] In order to improve the uniform distribution of gas in the bell mouth and thus facilitate the dust removal equipment to play a better role, the present application provides a flue gas dust collector with an adjustable distribution plate.

[0006] The present application provides a flue gas dust collector with adjustable distribution plate, which adopts the following technical solution:

[0007] A flue gas dust collector with adjustable distribution plate, comprising an air inlet pipe and a dust collector body, a bell mouth is arranged between the air inlet pipe and the dust collector body, the narrow end of the bell mouth is connected to the air inlet pipe, and the wide end of the bell mouth is connected to the dust collector body, a first airflow distribution plate and a second airflow distribution plate are arranged in the bell mouth, the second airflow distribution plate is arranged between the first airflow distribution plate and the dust collector body, a first guide component is arranged on a surface of the first airflow distribution plate away from the air inlet pipe, and a second guide component is arranged on a surface of the second airflow distribution plate close to the air inlet pipe, and the first guide component and the second guide component are used to guide part of the gas in the bell mouth to the middle part of the bell mouth;

[0008] The first air guide component includes a first transverse plate, a first transverse rotation axis, a first vertical plate and a first vertical rotation axis, the first transverse plate and the first vertical plate are arranged in a grid-like staggered manner, the first transverse plate is arranged on the first transverse rotation axis, the first vertical plate is arranged on the first vertical rotation axis, the first transverse rotation axis and the first vertical rotation axis are both arranged on the first airflow distribution plate, the second air guide component includes a second transverse plate, a second transverse rotation axis, a second vertical plate and a second vertical rotation axis, and the second air guide component is arranged in the same manner as the first air guide component;

[0010] By adopting the above technical scheme, when the gas enters the bell-shaped mouth between the dust collector body from the air intake pipe, due to the gradual increase in the shape interface of the bell-shaped mouth, the gas will gradually diffuse in the direction of smaller resistance, so the gas in the middle of the bell-shaped mouth will be reduced a lot, which will eventually lead to uneven distribution of gas inside the bell-shaped mouth. The first horizontal plate and the first vertical plate in the first guide component in the present application, and the second horizontal plate and the second vertical plate in the second guide component can guide part of the gas in the bell-shaped mouth to the middle of the bell-shaped mouth; the driving device in the present application can drive the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate to swing according to the gas flow rate in the air intake pipe. When the gas flow rate is large, the larger the deflection angle that drives the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate to swing is, and when the gas flow rate is small, the smaller the deflection angle that drives the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate to swing is, so as to achieve the purpose of guiding the gas in the bell-shaped mouth to the middle of the bell-shaped mouth. The gas distribution can be adjusted in real time. Compared with the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate that are welded and fixed in the prior art, or the manual swinging adjustment of the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate, the real-time adjustment of the present application can better and more timely guide the gas in the bell-mouth. Since most of the gas in the bell-mouth will diffuse in four directions along the four walls of the bell-mouth, the first horizontal plate and the second horizontal plate in the present application can guide the gas in two of the directions, and the first vertical plate and the second vertical plate can guide the gas in the other two directions, so that part of the gas diffused in four directions along the four walls of the bell-mouth is guided to the middle of the bell-mouth, and the reset component can drive the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate to swing and reset when the intake pipe does not pass gas into the bell-mouth, so as to make adjustments the next time the intake pipe passes gas into the bell-mouth.

[0012] By adopting the above technical solution, when the intake pipe inputs gas into the bell mouth, the vortex ring fan can be pushed to move, and the vortex ring fan drives the moving block to move to the position of the rotating ring. When the outer ring enters the rotating ring, the moving block is separated from the moving groove. At this time, the airflow drives the vortex ring fan to rotate, and the moving block abuts against the rotating block. The vortex ring fan drives the rotating ring to rotate synchronously. While the rotating ring rotates, the first connecting component installed on the rotating ring can drive the first horizontal plate and the first vertical plate to swing. While the rotating ring rotates, the second connecting component installed on the rotating ring can also drive the second horizontal plate and the second vertical plate to swing, so that the gas part diffused in four directions along the four walls of the bell mouth is drained to the middle of the bell mouth. When the intake pipe stops inputting gas into the bell mouth, the reset component drives the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate to reset, so that the rotating ring is driven to rotate and reset through the first connecting component and the second connecting component, and the reset component then pulls the vortex ring fan in the direction away from the rotating ring to achieve the reset of the vortex ring fan.

[0013] Optionally, the first connecting assembly includes a transverse steel wire rope, a longitudinal steel wire rope, a transverse connecting rod, a longitudinal connecting rod and a transmission member, the transverse connecting rod is arranged parallel to the first transverse rotating shaft, the longitudinal connecting rod is arranged parallel to the first vertical rotating shaft, and the transverse connecting rod and the longitudinal connecting rod are both arranged on the first airflow distribution plate, one end of the transverse steel wire rope is connected to the rotating ring, and the other end is wound around the first transverse rotating shaft, one end of the longitudinal steel wire rope is connected to the rotating ring, and the other end is wound around the first vertical rotating shaft, when the rotating ring rotates, the first transverse rotating shaft and the first vertical rotating shaft are respectively pulled and rotated by the transverse steel wire rope and the longitudinal steel wire rope, and the transmission member is arranged on the transverse connecting rod and the longitudinal connecting rod, and is used to drive all of the first transverse rotating shafts and the first vertical rotating shafts to rotate synchronously.

[0014] By adopting the above technical scheme, when the rotating ring rotates, the transverse steel wire rope and the longitudinal steel wire rope can be pulled, thereby realizing the rotation of the transverse connecting rod and the longitudinal connecting rod. When the transverse connecting rod rotates, the first transverse rotating shaft and the first transverse plate on the first transverse rotating shaft can be driven to swing through the transmission member. When the longitudinal connecting rod rotates, the first vertical rotating shaft and the first vertical plate on the first vertical rotating shaft can be driven to swing through the transmission member, thereby realizing the diversion of part of the gas in two flow directions along the inner walls of the two bell mouths in the bell mouth, and the second connecting component is arranged with the first connecting component to realize the diversion of part of the gas in two flow directions along the other two inner walls of the bell mouth in the bell mouth in the same way.

[0015] Optionally, the reset member includes a fixed ring, a connecting ring and a first elastic member, the connecting ring is rotatably arranged on the outer ring of the vortex ring fan, a connecting block is arranged on the outer wall of the connecting ring, and the connecting block is slidably arranged in the movable groove, the fixed ring is arranged on the side of the connecting ring away from the vortex ring fan, and is arranged on the inner wall of the intake pipe, and the first elastic member is arranged between the fixed ring and the connecting ring, and is used to make the connecting ring approach the position of the fixed ring.

[0016] By adopting the above technical solution, after the rotating ring rotates and resets, the first elastic member can drive the vortex ring fan to move away from the rotating ring through the connecting ring. When the air intake pipe introduces gas into the bell mouth, the gas flow rate will be very high, so it may cause damage to the vortex ring fan for a long time. The first elastic member in the present application can also buffer the impact of the airflow on the vortex ring fan, thereby increasing the service life of the vortex ring fan.

[0017] Optionally, the transmission member includes a transverse active bevel gear, a longitudinal active bevel gear, a transverse passive bevel gear and a longitudinal passive bevel gear, the transverse active bevel gear is arranged on the transverse connecting rod, the transverse passive bevel gear is arranged at the end of the first transverse rotating shaft and meshes with the transverse active bevel gear, the longitudinal active bevel gear is arranged on the longitudinal connecting rod, the longitudinal passive bevel gear is arranged at the end of the first vertical rotating shaft and meshes with the longitudinal active bevel gear.

[0018] By adopting the above technical solution, when the transverse connecting rod rotates, it drives the transverse active bevel gear to rotate. Since the transverse active bevel gear and the transverse passive bevel gear are meshed with each other, the first transverse rotation shaft can be driven to rotate, thereby realizing the swing of the first transverse plate. When the longitudinal connecting rod rotates, it drives the longitudinal active bevel gear to rotate. Since the longitudinal active bevel gear and the longitudinal driven bevel gear are meshed with each other, the first vertical rotation shaft can be driven to rotate, thereby realizing the swing of the first vertical plate.

[0019] Optionally, the reset assembly includes a first movable rod, a second movable rod and a sleeve, and the first movable rod, the second movable rod and the sleeve are provided in multiple groups, one end of the multiple groups of first movable rods are respectively rotatably connected to the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate, and the other end is movably telescopically connected to one end of the sleeve, one end of the multiple groups of second movable rods corresponds to the first movable rod and is respectively rotatably set on the first airflow distribution plate and the second airflow distribution plate, and the other end is movably telescopically connected to an end of the sleeve away from the first movable rod, a second elastic member is provided in the sleeve, and the second elastic member is provided between the first movable rod and the second movable rod.

When the gas is stopped from being introduced into the intake pipe, the second elastic member contracts and resets, thereby driving the first movable rod and the second movable rod to approach each other, thereby realizing the reset of the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate. When the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate are reset, the barrel wire rope drives the rotating ring to rotate in the opposite direction and reset, so as to facilitate the adjustment of the airflow in the bell mouth next time.

[0021] Optionally, a rope guide groove is provided on the inner wall of the bell mouth, and the rope guide groove is provided in multiple groups. The transverse steel wire rope and the longitudinal steel wire rope both pass through the rope guide groove and are connected to the rotating ring.

[0022] By adopting the above technical scheme, the guide rope groove can adjust the direction of the wire rope, and convert the swing amplitudes of the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate into the displacement of the connection between the horizontal wire rope, the longitudinal wire rope and the rotating ring, so as to achieve the same swing amplitude of the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate when deflected, thereby further improving the diversion effect on the gas in the bell mouth.

[0023] Optionally, a limiting structure is arranged between the inner wall of the air intake pipe and the rotating ring, the limiting structure comprising a limiting block and a limiting groove, the limiting block is arranged on the outer wall of the rotating ring, the limiting groove is opened on the inner wall of the air intake pipe, and when the rotating ring rotates, the limiting block is movably arranged in the limiting groove.

[0025] Optionally, the vortex ring fan also includes an inner ring, on which a turbofan is arranged.

[0026] By adopting the above technical solution, when the moving block on the turbofan abuts against the rotating block on the rotating block and stops rotating, the rotation of the turbofan can drain the gas in the intake pipe, concentrating more gas in the middle part of the intake pipe, thereby further improving the effect of draining the gas input into the bell mouth of the intake pipe to the middle part of the bell mouth.

[0027] Optionally, an eccentric block is provided on the turbofan.

[0028] By adopting the above technical solution, a vibration effect can be generated when the turbofan drives the eccentric block to rotate, thereby reducing the adhesion of dust on the turbofan and the turbo-ring fan, and ensuring the use effect of the turbofan and the turbo-ring fan after long-term use.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. When the gas enters the bell-shaped mouth between the dust collector bodies from the intake pipe, due to the gradually increasing shape interface of the bell-shaped mouth, the gas will gradually diffuse in the direction of smaller resistance, so the gas in the middle of the bell-shaped mouth will be reduced a lot, which will eventually lead to uneven distribution of gas inside the bell-shaped mouth. The first horizontal plate and the first vertical plate in the first guide assembly in the present application, and the second horizontal plate and the second vertical plate in the second guide assembly can guide part of the gas in the bell-shaped mouth to the middle of the bell-shaped mouth; the driving device in the present application can drive the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate to swing according to the gas flow rate in the intake pipe. When the gas flow rate is large, the larger the deflection angle that drives the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate to swing is, and when the gas flow rate is small, the smaller the deflection angle that drives the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate to swing is, so that the gas in the bell-shaped mouth can be separated The air intake vents are adjusted in real time. Compared with the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate that are welded and fixed in the prior art, or the manual swinging adjustment of the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate, the real-time adjustment of the present application can better and more timely guide the gas in the bell mouth. Since most of the gas in the bell mouth will diffuse in four directions along the four walls of the bell mouth, the first horizontal plate and the second horizontal plate in the present application can guide the gas in two of the directions, and the first vertical plate and the second vertical plate can guide the gas in the other two directions, so that part of the gas diffused in four directions along the four walls of the bell mouth is guided to the middle of the bell mouth, and the reset component can drive the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate to swing and reset when the intake pipe does not pass gas into the bell mouth, so as to make adjustments the next time the intake pipe passes gas into the bell mouth.

[0031] 2. After the rotating ring is rotated and reset, the first elastic member can drive the vortex ring fan to move away from the rotating ring through the connecting ring. When the air intake pipe passes gas into the bell mouth, the gas flow rate will be very high, so it may cause damage to the vortex ring fan for a long time. The first elastic member in the present application can also buffer the impact of the airflow on the vortex ring fan, thereby increasing the service life of the vortex ring fan;

[0032] 3. Since one end of the first movable rod is rotatably connected to the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate respectively, and one end of the second movable rod is rotatably arranged on the first airflow distribution plate and the second airflow distribution plate, when the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate swing, the second elastic member will be pulled and lengthened through the first movable rod and the second movable rod. When the gas is stopped from entering the air intake pipe, the second elastic member contracts and resets, thereby driving the first movable rod and the second movable rod to approach each other, so as to realize the reset of the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate. When the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate are reset, the barrel wire rope drives the rotating ring to rotate in the opposite direction and reset, so as to facilitate the adjustment of the airflow in the bell mouth next time;

[0034] 5. When the moving block on the vortex ring fan abuts against the rotating block on the rotating block and stops rotating, the rotation of the turbofan can drain the gas in the intake pipe, concentrate more gas in the middle of the intake pipe, thereby further improving the effect of draining the gas input into the bell mouth of the intake pipe to the middle of the bell mouth. When the moving block on the vortex ring fan abuts against the rotating block on the rotating block and stops rotating, the rotation of the turbofan can drain the gas in the intake pipe, concentrate more gas in the middle of the intake pipe, thereby further improving the effect of draining the gas input into the bell mouth of the intake pipe to the middle of the bell mouth.

[0044] The following is combined with Figure 1-7 This application is described in further detail.

[0045] The present application discloses a flue gas dust collector with adjustable distribution plate, referring to Figure 1 and Figure 2A flue gas dust collector with adjustable distribution plate comprises an air inlet pipe 1 and a dust collector body 2, a bell mouth 3 is installed between the air inlet pipe 1 and the dust collector body 2, the narrow end of the bell mouth 3 is welded to the air inlet pipe 1, and the wide end of the bell mouth 3 is welded to the dust collector body 2, a first airflow distribution plate 31 and a second airflow distribution plate 32 are welded in the bell mouth 3, the second airflow distribution plate 32 is installed between the first airflow distribution plate 31 and the dust collector body 2, a first guide component 4 is installed on the side of the first airflow distribution plate 31 away from the air inlet pipe 1, and a second guide component 5 is installed on the side of the second airflow distribution plate 32 close to the air inlet pipe 1.

The first transverse plate 41 and the first vertical plate 43 are installed in a grid-like staggered manner. The first transverse plate 41 is welded and installed on the first transverse rotation axis 42, and the first vertical plate 43 is installed on the first vertical rotation axis 44. The first transverse rotation axis 42 and the first vertical rotation axis 44 are both welded and installed on the first air flow distribution plate 31. The second air guide component 5 includes a second transverse plate 51, a second transverse rotation axis 52, a second vertical plate 53 and a second vertical rotation axis 54.

[0047] When the gas enters the bell mouth 3 between the dust collector body 2 from the air intake pipe 1, since the shape interface of the bell mouth 3 gradually becomes larger, the gas will gradually diffuse in the direction of smaller resistance. Therefore, the gas in the middle of the bell mouth 3 will be reduced a lot, which will eventually lead to uneven gas distribution inside the bell mouth 3. The first horizontal plate 41 and the first vertical plate 43 in the first guide component 4 in the present application, and the second horizontal plate 51 and the second vertical plate 53 in the second guide component 5 can guide part of the gas in the bell mouth 3 to the middle of the bell mouth 3; the driving device 6 in the present application can drive the first horizontal plate 41, the second horizontal plate 51, the first vertical plate 43 and the second vertical plate 53 to swing according to the gas flow rate in the air intake pipe 1. When the gas flow rate is large, the larger the deflection angle that drives the first horizontal plate 41, the second horizontal plate 51, the first vertical plate 43 and the second vertical plate 53 to swing is, the smaller the gas flow rate is. The smaller the deflection angle of the first horizontal plate 41, the second horizontal plate 51, the first vertical plate 43 and the second vertical plate 53 for swinging, the gas distribution in the bell-mouth 3 can be adjusted in real time.

The reset member 64 is installed on the outer ring 611 and the inner wall of the intake pipe 1.

[0049] When the air inlet pipe 1 inputs gas into the bell mouth 3, the vortex ring fan 61 can be pushed to move, and the vortex ring fan 61 drives the moving block 6111 to move toward the position of the rotating ring 62. When the outer ring 611 enters the rotating ring 62, the moving block 6111 separates from the moving groove 11. At this time, the airflow drives the vortex ring fan 61 to rotate, and the moving block 6111 abuts against the rotating block 621. The vortex ring fan 61 drives the rotating ring 62 to rotate synchronously. When the rotating ring 62 rotates, the first connecting component 65 installed on the rotating ring 62 can drive the first horizontal plate 41 and the first vertical plate 43 to swing. When the rotating ring 62 rotates, the rotating ring 62 can also The second connecting assembly 66 installed on the moving ring 62 drives the second transverse plate 51 and the second vertical plate 53 to swing, thereby guiding the gas part that diffuses in four directions along the four walls of the bell mouth 3 to the middle part of the bell mouth 3. When the intake pipe 1 stops inputting gas into the bell mouth 3, the reset assembly 7 drives the first transverse plate 41, the second transverse plate 51, the first vertical plate 43 and the second vertical plate 53 to reset, thereby driving the rotating ring 62 to rotate and reset through the first connecting assembly 65 and the second connecting assembly 66, and the reset member 64 then pulls the vortex ring fan 61 away from the rotating ring 62 to achieve the reset of the vortex ring fan 61.

One end of the transverse steel wire rope 651 is connected to the rotating ring 62, and the other end is wound around the first transverse steel wire rope 651. On the rotating shaft 42, one end of the longitudinal steel wire rope 652 is connected to the rotating ring 62, and the other end is wound around the first vertical rotating shaft 44. When the rotating ring 62 rotates, the first transverse rotating shaft 42 and the first vertical rotating shaft 44 are pulled and rotated by the transverse steel wire rope 651 and the longitudinal steel wire rope 652 respectively. The transmission member 655 is arranged on the transverse connecting rod 653 and the longitudinal connecting rod 654, and is used to drive all the first transverse rotating shafts 42 and the first vertical rotating shafts 44 to rotate synchronously.

[0051] When the rotating ring 62 rotates, the transverse steel wire rope 651 and the longitudinal steel wire rope 652 can be pulled, so as to realize the rotation of the transverse connecting rod 653 and the longitudinal connecting rod 654. When the transverse connecting rod 653 rotates, the first transverse rotating shaft 42 and the first transverse plate 41 on the first transverse rotating shaft 42 can be driven to swing through the transmission member 655. When the longitudinal connecting rod 654 rotates, the first vertical rotating shaft 44 and the first vertical plate 43 on the first vertical rotating shaft 44 can be driven to swing through the transmission member 655, so as to realize the diversion of part of the gas in two directions along the inner walls of the two bell mouths 3 in the bell mouth 3. The second connecting component 66 is arranged with the first connecting component 65 to realize the diversion of part of the gas in two directions along the inner walls of the other two bell mouths 3 in the bell mouth 3 in the same way.

[0052] Reference Figure 3 , Figure 4 and Figure 5 The reset member 64 in this embodiment includes a fixed ring 641, a connecting ring 642 and a first elastic member 643. The connecting ring 642 is rotatably arranged on the outer ring 611 of the vortex ring fan 61. A connecting block 6421 is arranged on the outer wall of the connecting ring 642. The connecting block 6421 is slidably arranged in the movable groove 11. The fixed ring 641 is arranged on the side of the connecting ring 642 away from the vortex ring fan 61 and is arranged on the inner wall of the intake pipe 1. The first elastic member 643 is arranged between the fixed ring 641 and the connecting ring 642, and is used to make the connecting ring 642 approach the position of the fixed ring 641.

[0053] After the rotating ring 62 is rotated and reset, the first elastic member 643 can drive the vortex ring fan 61 to move away from the rotating ring 62 through the connecting ring 642. When the air intake pipe 1 passes gas into the bell mouth 3, the gas flow rate will be very high, so it may cause damage to the vortex ring fan 61 for a long time. The first elastic member 643 in the present application can also buffer the impact of the airflow on the vortex ring fan 61, thereby increasing the service life of the vortex ring fan 61. In the present embodiment, the first elastic member 643 is a spring, and the spring is a preferred method of the present embodiment. In other embodiments, the first elastic member 643 may be an elastic telescopic rod, etc.

[0054] Reference Figure 6 The transmission member 655 includes a transverse active bevel gear 6551, a longitudinal active bevel gear 6552, a transverse passive bevel gear 6553 and a longitudinal passive bevel gear 6554. The transverse active bevel gear 6551 is arranged on the transverse connecting rod 653, the transverse passive bevel gear 6553 is arranged at the end of the first transverse rotating shaft 42 and meshes with the transverse active bevel gear 6551, the longitudinal active bevel gear 6552 is arranged on the longitudinal connecting rod 654, and the longitudinal passive bevel gear 6554 is arranged at the end of the first vertical rotating shaft 44 and meshes with the longitudinal active bevel gear 6552.

[0055] When the transverse connecting rod 653 rotates, it drives the transverse active bevel gear 6551 to rotate. Since the transverse active bevel gear 6551 and the transverse passive bevel gear 6553 are meshed with each other, the first transverse rotating shaft 42 can be driven to rotate, thereby realizing the swing of the first transverse plate 41. When the longitudinal connecting rod 654 rotates, it drives the longitudinal active bevel gear 6552 to rotate. Since the longitudinal active bevel gear 6552 and the longitudinal driven bevel gear are meshed with each other, the first vertical rotating shaft 44 can be driven to rotate, thereby realizing the swing of the first vertical plate 43.

[0056] When the gas input to the intake pipe 1 stops, refer to Figure 6 and Figure 7 , it is necessary to reset the swing of the first transverse plate 41, the second transverse plate 51, the first vertical plate 43 and the second vertical plate 53, so the reset component 7 in this embodiment includes a first movable rod 71, a second movable rod 72 and a sleeve 73, and the first movable rod 71, the second movable rod 72 and the sleeve 73 are provided with multiple groups, one end of the multiple groups of first movable rods 71 ​​are respectively rotatably connected with the first transverse plate 41, the second transverse plate 51, the first vertical plate 43 and the second vertical plate 53, and the other end is movably and telescopically connected with one end of the sleeve 73, one end of the multiple groups of second movable rods 72 is respectively rotatably set on the first airflow distribution plate 31 and the second airflow distribution plate 32 corresponding to the first movable rod 71, and the other end is movably and telescopically connected with one end of the sleeve 73 away from the first movable rod 71, and a second elastic member 74 is provided in the sleeve 73, and the second elastic member 74 is provided between the first movable rod 71 and the second movable rod 72.

[0057] Since one end of the first movable rod 71 is rotatably connected to the first transverse plate 41, the second transverse plate 51, the first vertical plate 43 and the second vertical plate 53 respectively, and one end of the second movable rod 72 is rotatably arranged on the first airflow distribution plate 31 and the second airflow distribution plate 32, when the first transverse plate 41, the second transverse plate 51, the first vertical plate 43 and the second vertical plate 53 swing, the first movable rod 71 and the second movable rod 72 will pull the second elastic member 74 to lengthen, and when the gas is stopped from being introduced into the intake pipe 1, the second elastic member 74 will shrink and return to its original position, thereby bringing The first movable rod 71 and the second movable rod 72 are moved closer to each other to realize the resetting of the first transverse plate 41, the second transverse plate 51, the first vertical plate 43 and the second vertical plate 53. While the first transverse plate 41, the second transverse plate 51, the first vertical plate 43 and the second vertical plate 53 are reset, the barrel wire rope drives the rotating ring 62 to rotate in the opposite direction to reset, so as to facilitate the adjustment of the airflow in the bell mouth 3 next time. In this embodiment, the second elastic member 74 is a spring, and the spring is a preferred method of this embodiment. In other embodiments, the second elastic member 74 can be an elastic block, etc.

[0058] In order to make the swing deflection angles of the first horizontal plate 41, the second horizontal plate 51, the first vertical plate 43 and the second vertical plate 53 consistent, refer to Figure 2 In this embodiment, a guide rope groove is provided on the inner wall of the bell mouth 3, and multiple guide rope grooves are provided. The transverse steel wire rope 651 and the longitudinal steel wire rope 652 are both passed through the guide rope grooves and connected to the rotating ring 62. The guide rope groove can adjust the direction of the steel wire rope, and the swing amplitude of the first transverse plate 41, the second transverse plate 51, the first vertical plate 43 and the second vertical plate 53 are all converted into the displacement of the connection between the transverse steel wire rope 651 and the longitudinal steel wire rope 652 and the rotating ring 62, so as to achieve the same swing amplitude of the first transverse plate 41, the second transverse plate 51, the first vertical plate 43 and the second vertical plate 53 when deflected, and further improve the guiding effect of the gas in the bell mouth 3.

[0059] In order to avoid the deflection angle of the first horizontal plate 41, the second horizontal plate 51, the first vertical plate 43 and the second vertical plate 53 being too large due to the excessive gas flow rate, which reduces the air permeability of the first airflow distribution plate 31 and the second airflow distribution plate 32, refer to Figure 3 and Figure 5 A limiting structure 8 is provided between the inner wall of the intake pipe 1 and the rotating ring 62. The limiting structure 8 includes a limiting block 81 and a limiting groove 82. The limiting block 81 is provided on the outer wall of the rotating ring 62, and the limiting groove 82 is provided on the inner wall of the intake pipe 1. When the rotating ring 62 rotates, the limiting block 81 is movably provided in the limiting groove 82. When the rotating ring 62 rotates, the limiting block 81 moves in the limiting groove 82 to limit the rotation angle of the rotating ring 62.

[0060] After the vortex ring fan 61 is used for a long time, a lot of dust may be attached to the vortex ring fan 61, thereby affecting the normal use of the vortex ring fan 61. Figure 3 Therefore, the turbofan 61 in this embodiment also includes an inner ring 612, on which a turbofan 9 is arranged, and on which an eccentric block 91 is arranged; when the moving block 6111 on the turbofan 61 abuts against the rotating block 621 on the rotating block 621 and stops rotating, the rotation of the turbofan 9 can drain the gas in the intake pipe 1, and concentrate more gas in the middle part of the intake pipe 1, thereby further improving the effect of draining the gas input into the bell mouth 3 by the intake pipe 1 to the middle part of the bell mouth 3; when the turbofan 9 drives the eccentric block 91 to rotate, a vibration effect can be generated, thereby reducing the dust adhesion on the turbofan 9 and the turbofan 61, and the use effect of the turbofan 9 and the turbofan 61 can be guaranteed after the turbofan 9 and the turbofan 61 are used for a long time.

[0061] The implementation principle of a flue gas dust collector with adjustable distribution plate in the embodiment of the present application is:

[0062] When the air inlet pipe 1 inputs gas into the bell mouth 3, the vortex ring fan 61 can be pushed to move, and the vortex ring fan 61 drives the moving block 6111 to move to the position of the rotating ring 62. When the outer ring 611 enters the rotating ring 62, the moving block 6111 separates from the moving groove 11. At this time, the airflow drives the vortex ring fan 61 to rotate, and the moving block 6111 abuts against the rotating block 621. The vortex ring fan 61 drives the rotating ring 62 to rotate synchronously; when the rotating ring 62 rotates, the transverse wire rope 651 and the longitudinal wire rope 652 can be pulled, so as to realize the rotation of the transverse connecting rod 653 and the longitudinal connecting rod 654. When the transverse connecting rod 653 rotates, the transmission member 655 can drive the first transverse rotating shaft 42 and the first transverse plate 41 on the first transverse rotating shaft 42 to swing. When the longitudinal connecting rod 654 rotates, the transmission member 655 can drive the first vertical rotating shaft 44 and the first vertical plate 43 on the first vertical rotating shaft 44 to swing, thereby realizing the diversion of part of the gas in two directions along the inner walls of the two bell mouths 3 in the bell mouth 3. The second connecting component 66 is arranged together with the first connecting component 65 to similarly realize the diversion of part of the gas in two directions along the inner walls of the other two bell mouths 3 in the bell mouth 3.
