Description

Technical Field

[0001] This application relates to the technical field of spray cleaning inside dust collectors, and in particular to a dust collector with a rotary high-efficiency spray washing function. Background Technique

[0002] At present, wet electrostatic precipitators are efficient flue gas purification devices widely used in desulfurization towers. Their main function is to remove fine particulate matter and gaseous pollutants in flue gas. The working principle is to charge the particulate matter in the flue gas through an electric field and then capture these charged particulate matter using water mist. This device has the characteristics of high-efficiency dust removal, desulfurization function, low energy consumption, and strong adaptability. It can effectively remove fine particulate matter such as PM2.5 and combine with desulfurization reactants to remove harmful gases such as sulfur dioxide. Due to its high purification ability, wet electrostatic precipitators play an important role in improving environmental quality and reducing industrial pollution.

[0003] In the prior art, a wet electrostatic precipitator includes an anode tube, a cathode wire, a suspension rod, a housing, a mounting frame, and a flushing mechanism. The anode tube and the cathode wire are both installed inside the housing, and the cathode wire is suspended inside the anode tube through the suspension rod. The flushing mechanism is installed above the inner part of the housing. The anode tube and the cathode wire jointly form a strong electric field. When the flue gas containing pollutants flows through the electric field, the particulate matter is charged under the influence of the electric field and then adheres to the anode tube. When there is more particulate matter adhering to the anode tube, the anode tube needs to be flushed. The flushing mechanism used to flush the anode tube is usually a water pipe arranged linearly on the mounting frame, and nozzles are installed on the water pipe.

[0004] For the above related technologies, when there are more anode tubes, more nozzles are required for the flushing mechanism. When the number of installed nozzles increases, the water pressure supplied to the nozzles for flushing will be evenly divided, which may result in a relatively small flushing water pressure for a single nozzle. Moreover, the positions of the nozzles are fixed, so there may be flushing blind spots. After using the nozzles for a long time, they may also become blocked, making maintenance more difficult. Therefore, improvements are made to this. Summary of the Invention

[0005] In order to reduce the flushing blind spots of the nozzles while ensuring the flushing water pressure of the nozzles and realizing automatic cleaning of the nozzles, this application provides a dust collector with a rotary high-efficiency spray washing function.

[0006] A dust collector with a rotary high-efficiency spray washing function provided by this application adopts the following technical solutions:

[0007] A dust collector with a rotary high-efficiency spray rinsing function, comprising a dust collector body, the dust collector body including a housing and a suspension rod, a rinsing fan blade is arranged inside the housing, multiple groups of the rinsing fan blades are arranged at circumferential intervals with the vertical axis of the housing as the center, the rinsing fan blade includes a tip and an arc end, the tips of multiple groups of the rinsing fan blades are arranged close to the vertical axis of the housing, the arc ends of multiple groups of the rinsing fan blades are all movably arranged on the inner wall of the housing, a water inlet is arranged on the housing, a flexible connection pipe is arranged on the water inlet, multiple internal pipelines are opened inside the rinsing fan blade, the multiple internal pipelines are communicated with each other, the water inlet is communicated with the internal pipeline through the flexible connection pipe, the internal pipelines of multiple groups of the rinsing fan blades are communicated with each other, nozzles for rinsing the dust enriched in the dust collector are arranged at intervals on the internal pipeline, a driving component for rotating multiple groups of the rinsing fan blades around the vertical axis of the housing is arranged on the housing, an activity groove corresponding to the shape of the internal pipeline is opened inside the rinsing fan blade, the activity groove is located on the side of the internal pipeline away from the nozzle, and the activity groove is communicated with the internal pipeline, a dredging component for preventing the nozzle from being blocked is arranged in the activity groove, a fixing plate is further arranged inside the housing, the fixing plate is arranged below the rinsing fan blade, and a swinging mechanism for swinging the nozzle is arranged on the fixing plate and the rinsing fan blade.

[0008] By adopting the above technical solution, the drive component in the present application can drive the flushing fan blade to rotate. Since the internal pipeline is provided inside the flushing fan blade, the water inlet on the housing is connected to the internal pipeline through a flexible pipe, and nozzles are installed on the internal pipeline, the water inlet can output flushing water to the nozzles through the internal pipeline. When the drive component drives the flushing fan blade to rotate, the flushing of the anode tube is realized. Compared with the previous flushing method of densely arranging nozzles on the mounting rack, installing the nozzles on the flushing fan blade can effectively reduce the number of nozzles to be installed, reduce the maintenance cost after long-term use of the nozzles, and reducing the number of nozzles can effectively increase the flow rate of the flushing water output by a single nozzle, which can better flush the stubborn stains attached to the anode tube. And adopting the previous flushing method, the position of the nozzle is fixed, so there are flushing blind spots. In the present application, the flushing fan blade drives the nozzles to rotate synchronously, reducing the existence of flushing blind spots and enabling more comprehensive flushing of the anode tube. Since the anode tube is not flushed simultaneously when the dust collector body is working, there may be some dust that is not adsorbed by the anode tube, thus causing blockage of the nozzles. And long-term use of the nozzles may also cause blockage of the nozzles due to the accumulation of water scale. The dredging component in the present application can block the water outlet of the nozzle after each flushing of the anode tube to prevent dust that is not adsorbed by the anode tube from entering and causing blockage, and can automatically open the water outlet of the nozzle during flushing. While opening and blocking the water outlet of the nozzle, the cleaning work of the water scale at the water outlet of the nozzle is completed, further improving the service life of the nozzle and the flushing effect on the anode tube. The swinging mechanism can drive the nozzles to swing when the flushing fan blade rotates, thereby further increasing the range that the nozzles can flush, further reducing the flushing blind spots, and further improving the flushing effect on the anode tube.

[0009] Optionally, the drive component includes a drive motor, a rack, a gear, a guide rail and a roller. The drive motor is arranged on the outer peripheral wall of the housing, and the output shaft penetrates through the housing. The gear is arranged on the output shaft of the drive motor. The rack is arranged on the surface of the flushing fan blade away from the fixing plate, and the gear and the rack are meshed with each other. The guide rail is arranged on the inner wall of the housing. The arc end of the flushing fan blade is arranged on the guide rail. The roller is arranged on the flushing fan blade and is located between the arc end of the flushing fan blade and the guide rail.

[0010] By adopting the above technical solution, the driving motor drives the gear to rotate. Since the gear meshes with the rack and the driving motor is fixedly installed, the rotation of the flushing fan blade can be realized, and the roller can be driven to move on the guide rail, so as to realize the synchronous rotation of the nozzle driven by the rotation of the flushing fan blade, and the swing of the nozzle under the action of the swing mechanism, so as to reduce the flushing blind area of the nozzle and improve the flushing effect on the anodic tube.

[0011] Optionally, the dredging component includes a lifting plate, a dredging needle and a lifting block. The lifting plate and the lifting block are both arranged in the movable groove. There are multiple groups of the lifting blocks, and multiple groups of the lifting blocks are arranged on the lifting plate. The dredging needles are provided in multiple groups corresponding to the number of the nozzles, and multiple groups of the dredging needles are arranged on the side of the lifting plate close to the nozzles corresponding to the positions of the nozzles. The densities of the lifting plate and the lifting block are both less than that of water. When water is injected into the internal pipeline through the flexible connecting pipe at the water inlet, the lifting plate and the lifting block float on the water surface, and the dredging needle is separated from the nozzle. When the water inlet stops injecting water into the internal pipeline, the lifting plate and the lifting block descend, and the dredging needle enters the nozzle to dredge the nozzle.

[0012] By adopting the above technical solution, when water is injected into the internal pipeline through the flexible connecting pipe at the water inlet, since the densities of the lifting plate and the lifting block are less than that of water, the lifting plate and the lifting block float on the water surface, and the lifting block can better provide buoyancy for the lifting plate, so that the dredging needle is better separated from the nozzle. When the water inlet stops injecting water into the internal pipeline, the lifting plate and the lifting block descend, and the dredging needle enters the nozzle to dredge and block the nozzle, so as to prevent the dust not adsorbed by the anodic tube from entering the water outlet of the nozzle and causing blockage. And while opening and blocking the water outlet of the nozzle, the scale cleaning work at the water outlet of the nozzle is completed, further improving the service life of the nozzle and the flushing effect on the anodic tube.

[0013] Optionally, the swing mechanism includes a corrugated pipe, a fixed frame, a fixed ring, a rotating ring and a swing structure. The corrugated pipe is arranged between the nozzle and the flushing fan blade, and is communicated with the internal pipeline at one end and connected with the nozzle at the other end. The fixed frame is arranged on the side of the flushing fan blade close to the fixed plate. The fixed ring is arranged at the end of the fixed frame away from the flushing fan blade. The outer wall of the rotating ring is rotatably arranged at both ends along the diameter in the fixed ring. The nozzle is rotatably arranged in the rotating ring, and the rotating directions of the rotating ring and the nozzle are perpendicular to each other. The swing structure is used to deflect the angle between the nozzle and the fixed plate when the nozzle moves.

[0014] By adopting the above technical solution, when the flushing fan blade drives the nozzle to move, under the action of the swinging structure, the angle between the nozzle and the fixed plate deflects. When the angle between the nozzle and the fixed plate deflects, the bellows will elongate, and the rotating ring will rotate within the fixed ring, and the nozzle will rotate within the inner fixed ring, thereby realizing the swinging of the nozzle to increase the flushing area and flushing angle of the nozzle, so as to better flush the anodic tube and improve the flushing effect on the anodic tube.

[0015] Optionally, the swinging structure includes a plurality of arc-shaped grooves. One end of the nozzle away from the bellows is arranged in the arc-shaped grooves. The plurality of arc-shaped grooves are respectively arranged below the internal pipelines corresponding to the positions of the plurality of internal pipelines. The two arc-shaped side walls of the arc-shaped grooves are parallel to each other and are arranged in an inclined continuous wave shape.

[0016] By adopting the above technical solution, since the two arc-shaped side walls of the arc-shaped groove are parallel to each other and are arranged in an inclined continuous wave shape, when one end of the nozzle away from the bellows moves in the arc-shaped groove, it will swing back and forth due to the change of the side wall of the arc-shaped groove, thereby realizing the increase of the flushing area and flushing angle of the nozzle, so as to better flush the anodic tube and improve the flushing effect on the anodic tube.

[0017] Optionally, the plurality of internal pipelines are arranged at intervals and are all parallel to the arc-shaped end of the flushing fan blade. The internal pipelines closer to the arc-shaped end of the flushing fan blade are longer and are provided with more nozzles.

[0018] By adopting the above technical solution, the linear velocity of the internal pipeline farther away from the arc-shaped end of the flushing fan blade is slower, and the flushing effect time of a single nozzle on the anodic tube below is longer. The linear velocity of the internal pipeline closer to the arc-shaped end of the flushing fan blade is faster, and the flushing time of a single nozzle on the anodic tube below is shorter. The internal pipelines closer to the arc-shaped end of the flushing fan blade are longer and are provided with more nozzles, which can effectively improve the flushing effect on the anodic tube closer to the arc-shaped end of the flushing fan blade.

[0019] Optionally, a positioning column is arranged in the movable groove, and the lifting plate is slidably lifted on the positioning column.

[0020] By adopting the above technical solution, the positioning column can improve the lifting accuracy of the lifting plate, so as to more accurately insert the dredging needle into the water outlet of the nozzle to clean the water outlet of the nozzle.

[0021] Optionally, an elastic member is arranged on the positioning column, and the elastic member is used to provide a force for pulling the lifting plate towards the fixed plate.

[0022] By adopting the above technical solution, the elastic member can increase the pulling force of the lifting plate towards the fixed plate. When a large number of water outlets in the nozzle are blocked, the greater pulling force can better dredge the water outlets of the nozzle.

[0023] Optionally, two groups of limiting rods are arranged at both ends of the guide rail. The two groups of limiting rods are respectively arranged at both ends of the arc-shaped end of the flushing fan blade, and are used to limit the position of the roller when the roller moves, so as to avoid collision between the flushing fan blade and the suspension rod.

[0024] By adopting the above technical solution, the two groups of limiting rods can respectively limit the flushing fan blade when it rotates in the positive and negative directions, so as to avoid separation between the roller and the guide rail, and avoid damage caused by collision between the flushing fan blade and the suspension rod.

[0025] Optionally, an avoidance groove is formed in the flushing fan blade corresponding to the suspension rod.

[0026] By adopting the above technical solution, the avoidance groove can realize the dislocation between the flushing fan blade and the suspension rod, so that the anodic tube can be flushed more comprehensively.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The main purpose of the present application is to improve the flushing effect on the anodic tube in the wet electrostatic precipitator. Since there is a suspension rod for hoisting the cathode wire in the wet electrostatic precipitator, the existence of the suspension rod causes the flushing mechanism in the prior art to include a large number of linearly arranged water pipes, and a large number of nozzles are installed on the water pipes, so as to avoid the position interference between the flushing mechanism and the suspension rod. However, in the present application, the fixed drive assembly can drive the flushing fan blade to rotate forward and backward and an avoidance groove is formed in the flushing fan blade to improve the coverage rate of the anodic tube on the moving path of the nozzle. Since an internal pipeline is provided inside the flushing fan blade, and the water inlet on the housing is connected to the internal pipeline through a flexible joint, and nozzles are installed on the internal pipeline, the water inlet can output flushing water to the nozzle through the internal pipeline. When the drive motor drives the flushing fan blade to rotate, the flushing of the anodic tube is realized. Compared with the conventional flushing method of covering the mounting frame with nozzles, installing the nozzles on the flushing fan blade can effectively reduce the number of nozzles to be installed, reduce the maintenance cost after long-term use of the nozzles, and reducing the number of nozzles can effectively increase the flow rate of the flushing water output by a single nozzle, which can better flush the stubborn stains attached to the anodic tube. And adopting the conventional flushing method, the position of the nozzle is fixed and there are blind spots. In the present application, the flushing fan blade drives the nozzle to rotate synchronously, reducing the existence of flushing blind spots, and can flush the anodic tube more comprehensively;

[0029] 2. Since the anode tubes are not flushed simultaneously when the dust collector body is working, there may be some dust that is not adsorbed by the anode tubes, which may clog the nozzles. Also, the nozzles may become clogged due to the accumulation of scale after long-term use. When water is injected into the internal pipeline through the water inlet via a flexible pipe in this application, since the density of the lifting plate and the lifting block is less than that of water, the lifting plate and the lifting block float on the water surface. The lifting block can better provide buoyancy for the lifting plate, so that the dredging needle can be better separated from the nozzle. When the water inlet stops injecting water into the internal pipeline, the lifting plate and the lifting block descend, and the dredging needle enters the nozzle to dredge and block the nozzle, thus preventing the dust that is not adsorbed by the anode tubes from entering the water outlet of the nozzle and causing blockage. At the same time as opening and blocking the water outlet of the nozzle, the scale cleaning work at the water outlet of the nozzle is completed, further improving the service life of the nozzle and the flushing effect on the anode tubes;

[0030] 3. Since the two arc-shaped side walls of the arc-shaped groove are parallel to each other and are arranged in an inclined continuous wave shape, when the end of the nozzle far from the corrugated pipe moves in the arc-shaped groove, it will swing back and forth due to the change of the side wall of the arc-shaped groove. Therefore, when the flushing fan blade drives the nozzle to move, the angle between the nozzle and the fixed plate deflects under the action of the arc-shaped groove. When the angle between the nozzle and the fixed plate deflects, the corrugated pipe will elongate, and the rotating ring will rotate within the fixed ring, and the nozzle will rotate within the inner fixed ring, so as to realize the swinging of the nozzle, increase the flushing area and flushing angle of the nozzle, and thus better flush the anode tubes and improve the flushing effect on the anode tubes;

[0031] 4. The linear velocity of the internal pipeline farther away from the arc-shaped end of the flushing fan blade is slower, and the flushing effect time of a single nozzle on the anode tube below is longer. The linear velocity of the internal pipeline closer to the arc-shaped end of the flushing fan blade is faster, and the flushing time of a single nozzle on the anode tube below is shorter. The longer the internal pipeline closer to the arc-shaped end of the flushing fan blade and the more nozzles arranged can effectively improve the flushing effect on the anode tubes closer to the arc-shaped end of the flushing fan blade.

Specific embodiments

[0040] The following will further describe the present application in detail with reference to the attached Figures 1-6 drawings.

[0041] An embodiment of the present application discloses a dust collector with a rotary high-efficiency spray flushing function. Refer to Figure 1 、 Figure 2 and Figure 5, a dust collector with a rotary high-efficiency spray rinsing function, comprising a dust collector body 1. The dust collector body 1 includes a housing 11 and a suspension rod 12. A rinsing fan blade 2 is rotatably installed inside the housing 11. Multiple groups of rinsing fan blades 2 are rotatably installed. The multiple groups of rinsing fan blades 2 are circumferentially spaced with the vertical axis of the housing 11 as the center. The rinsing fan blade 2 includes a tip and an arc end. The tips of the multiple groups of rinsing fan blades 2 are installed close to the vertical axis of the housing 11, and the arc ends of the multiple groups of rinsing fan blades 2 are all movably installed on the inner wall of the housing 11. An inlet is installed on the housing 11, and a flexible connection pipe 3 is installed on the inlet. Multiple internal pipelines 21 are opened inside the rinsing fan blade 2. The multiple internal pipelines 21 communicate with each other. The inlet is communicated with the internal pipeline 21 through the flexible connection pipe 3. The internal pipelines 21 of the multiple groups of rinsing fan blades 2 communicate with each other. Nozzles 22 are installed at intervals on the internal pipeline 21. The multiple internal pipelines 21 are spaced and all parallel to the arc end of the rinsing fan blade 2. The internal pipeline 21 closer to the arc end of the rinsing fan blade 2 is longer and more nozzles 22 are arranged. A driving assembly 4 is installed on the housing 11. An activity groove 23 is opened inside the rinsing fan blade 2 corresponding to the shape of the internal pipeline 21. The activity groove 23 is located on the side of the internal pipeline 21 away from the nozzle 22, and the activity groove 23 communicates with the internal pipeline 21. A dredging assembly 5 is installed in the activity groove 23. A fixing plate 6 is also welded and installed inside the housing 11. The fixing plate 6 is welded and installed below the rinsing fan blade 2. A swing mechanism 61 is installed on the fixing plate 6 and the rinsing fan blade 2.

[0042] In this embodiment, multiple internal pipelines 21 are opened inside the rinsing fan blade 2, and the inlet on the housing 11 is communicated with the internal pipeline 21 through the flexible connection pipe 3, and nozzles 22 are installed on the internal pipeline 21. Therefore, the inlet can output rinsing water to the nozzle 22 through the internal pipeline 21. Since the linear velocity of the internal pipeline 21 farther from the arc end of the rinsing fan blade 2 is slower, the rinsing effect time of a single nozzle 22 on the lower anodic tube is longer, and the linear velocity of the internal pipeline 21 closer to the arc end of the rinsing fan blade 2 is faster, and the rinsing time of a single nozzle 22 on the lower anodic tube is shorter. Therefore, the internal pipeline 21 closer to the arc end of the rinsing fan blade 2 is longer and more nozzles 22 are arranged, which can effectively improve the rinsing effect of the anodic tube close to the arc end of the rinsing fan blade 2.

[0043] In this embodiment, the driving component 4 can drive the flushing fan blade 2 to rotate. When the driving component 4 drives the flushing fan blade 2 to rotate, the flushing of the anode tube is realized. Compared with the conventional flushing method in which nozzles 22 are densely arranged on the mounting rack, mounting the nozzles 22 on the flushing fan blade 2 can effectively reduce the number of nozzles 22 to be installed, reduce the maintenance cost after long-term use of the nozzles 22, and reducing the number of nozzles 22 can effectively increase the flow rate of the flushing water output by a single nozzle 22, which can better flush the stubborn stains attached to the anode tube. Moreover, in the conventional flushing method, the position of the nozzles 22 is fixed, resulting in flushing blind spots. However, in this embodiment, the flushing fan blade 2 drives the nozzles 22 to rotate synchronously, reducing the existence of flushing blind spots and enabling more comprehensive flushing of the anode tube. Since the anode tube is not flushed simultaneously when the dust collector body 1 is working, there may be some dust that is not adsorbed by the anode tube, thus causing blockage of the nozzles 22. And long-term use of the nozzles 22 may also cause blockage of the nozzles 22 due to the accumulation of water scale. The dredging component 5 in this embodiment can block the water outlet of the nozzles 22 after each flushing of the anode tube to prevent dust that is not adsorbed by the anode tube from entering and causing blockage, and can automatically open the water outlet of the nozzles 22 during flushing. While opening and blocking the water outlet of the nozzles 22, the cleaning work of the water scale at the water outlet of the nozzles 22 is completed, further improving the service life of the nozzles 22 and the flushing effect on the anode tube. The swinging mechanism 61 can drive the nozzles 22 to swing when the flushing fan blade 2 rotates, thereby further increasing the range that the nozzles 22 can flush, further reducing the flushing blind spots, and further improving the flushing effect on the anode tube.

[0044] Referring to Figure 1 and Figure 2 , in this embodiment, four groups of flushing fan blades 2 are installed. Avoidance grooves 9 corresponding to the suspension rods 12 are provided on the four groups of flushing fan blades 2. The avoidance grooves 9 can realize the dislocation between the flushing fan blades 2 and the suspension rods 12, so as to more comprehensively flush the anode tube. There are four suspension rods 12 in this embodiment, and they are arranged in central symmetry. Therefore, the four groups of flushing fan blades 2 in this embodiment perform a forward and reverse rotation movement of 22.5° around the vertical axis of the housing 11 under the action of the driving component 4. In other embodiments, the number of flushing fan blades 2 can be adjusted according to actual needs.

[0045] To realize the rotational drive of the flushing fan blade 2, referring to Figure 2 and Figure 3, in this embodiment, the driving component 4 includes a driving motor 41, a rack 42, a gear 43, a guide rail 44 and a roller 45. The driving motor 41 is fixedly installed on the outer peripheral wall of the housing 11, and the output shaft penetrates and is installed in the housing 11. The gear 43 is welded to the output shaft of the driving motor 41. The rack 42 is welded to the side of the flushing fan blade 2 away from the fixing plate 6, and the gear 43 and the rack 42 are meshed with each other. The guide rail 44 is welded to the inner wall of the housing 11. The arc end of the flushing fan blade 2 is located on the guide rail 44. The roller 45 is installed on the flushing fan blade 2 and is installed between the arc end of the flushing fan blade 2 and the guide rail 44. Two groups of limiting rods 8 are fixedly installed at both ends of the guide rail 44, and the two groups of limiting rods 8 are respectively installed at both ends of the arc end of the flushing fan blade 2. The driving motor 41 drives the gear 43 to rotate. Since the gear 43 and the rack 42 are meshed with each other and the driving motor 41 is fixedly installed, the rotation of the flushing fan blade 2 can be realized, and the roller 45 can be driven to move on the guide rail 44, so as to realize the synchronous rotation of the nozzle 22 driven by the rotation of the flushing fan blade 2 and the swing of the nozzle 22 under the action of the swing mechanism 61, so as to achieve the effect of reducing the flushing blind area of the nozzle 22 and improving the flushing effect on the anode tube. The two groups of limiting rods 8 can respectively limit the flushing fan blade 2 when it rotates in the positive and negative directions, so as to prevent the separation between the roller 45 and the guide rail 44 and avoid the damage caused by the collision between the flushing fan blade 2 and the suspension rod 12.

[0046] After the nozzle 22 is used for a long time, the nozzle 22 may be blocked due to the accumulation of scale or the dust not adsorbed by the anode tube in the dust collector, thereby reducing the flushing effect on the anode tube. Refer to Figure 3 , Figure 4 and Figure 5, so the dredging component 5 in this embodiment includes a lifting plate 51, a dredging needle 52 and a lifting block 53, the lifting plate 51 and the lifting block 53 are all installed in the movable groove 23, the lifting block 53 is integrally provided with multiple groups, and the multiple groups of lifting blocks 53 are all integrally arranged on the lifting plate 51, the dredging needle 52 is installed in multiple groups corresponding to the number of nozzles 22, and the multiple groups of dredging needles 52 are installed on the side of the lifting plate 51 close to the nozzle 22 corresponding to the position of the nozzle 22, the density of the lifting plate 51 and the lifting block 53 are both less than that of water, and a positioning column 7 is installed in the movable groove 23, the lifting plate 51 is slidably lifted and installed on the positioning column 7, and an elastic member 71 is installed on the positioning column 7; when the water inlet is injected into the internal pipeline 21 through the flexible pipe 3, since the density of the lifting plate 51 and the lifting block 53 is less than that of water, the lifting plate 51 and the lifting block 53 float on the water surface, and the lifting block 53 can better provide buoyancy for the lifting plate 51, so that the dredging needle 52 is better separated from the nozzle 22, when the water inlet stops moving inward When water is injected into the pipe 21, the lifting plate 51 and the lifting block 53 descend, and the unblocking needle 52 enters the nozzle 22 to unblock and block the nozzle 22, thereby preventing dust that is not adsorbed by the anode tube from entering the water outlet of the nozzle 22 and causing blockage. At the same time, the water outlet of the nozzle 22 is opened and blocked, and the scale cleaning work at the water outlet of the nozzle 22 is completed, thereby further improving the service life of the nozzle 22 and the flushing effect of the anode tube. The positioning column 7 can improve the lifting accuracy of the lifting plate 51, so that the unblocking needle 52 can be more accurately inserted into the water outlet of the nozzle 22 to clean the water outlet of the nozzle 22. The elastic member 71 can increase the pulling force of the lifting plate 51 toward the fixed plate 6. When the water outlet in the nozzle 22 is blocked more, the larger pulling force can better unblock the water outlet of the nozzle 22. In this embodiment, the elastic member 71 is a spring, and the spring is a preferred embodiment of this embodiment. In other embodiments, the elastic member 71 can be an elastic cushion layer.

[0047] Reference Figure 5 and Figure 6, the swing mechanism 61 includes a corrugated pipe 611, a fixing bracket 612, a fixing ring 613, a rotating ring 614 and a swing structure 615. The corrugated pipe 611 is installed between the nozzle 22 and the flushing fan blade 2, with one end communicating with the internal pipeline 21 and the other end connected to the nozzle 22. The fixing bracket 612 is welded and installed on the side of the flushing fan blade 2 close to the fixing plate 6. The fixing ring 613 is welded and installed at the end of the fixing bracket 612 away from the flushing fan blade 2. The outer wall of the rotating ring 614 is rotatably installed at both ends along the diameter within the fixing ring 613. The nozzle 22 is rotatably installed within the rotating ring 614, and the rotating directions of the rotating ring 614 and the nozzle 22 are perpendicular to each other. The swing structure 615 includes a plurality of arc-shaped grooves 6151. The end of the nozzle 22 away from the corrugated pipe 611 is installed within the arc-shaped grooves 6151. The plurality of arc-shaped grooves 6151 are respectively opened below the internal pipeline 21 corresponding to the positions of the plurality of internal pipelines 21. The two arc-shaped side walls of the arc-shaped groove 6151 are parallel to each other and are in an inclined continuous wavy shape. Since the two arc-shaped side walls of the arc-shaped groove 6151 are parallel to each other and are arranged in an inclined continuous wavy shape, when the end of the nozzle 22 away from the corrugated pipe 611 moves within the arc-shaped groove 6151, it will swing back and forth due to the change of the side wall of the arc-shaped groove 6151. Therefore, when the flushing fan blade 2 drives the nozzle 22 to move, under the action of the swing structure 615, the angle between the nozzle 22 and the fixing plate 6 deflects. When the angle between the nozzle 22 and the fixing plate 6 deflects, the corrugated pipe 611 will elongate, and the rotating ring 614 will rotate within the fixing ring 613, and the nozzle 22 will rotate within the fixing ring 613, thereby realizing the swing of the nozzle 22, increasing the flushing area and flushing angle of the nozzle 22, so as to better flush the positive electrode tube and improve the flushing effect on the positive electrode tube.

[0048] The implementation principle of an electrostatic precipitator with a rotary high-efficiency spray flushing function in an embodiment of the present application is as follows:

[0049] When a more comprehensive flushing of the positive electrode tube is required, the driving motor 41 is started. The driving motor 41 drives the gear 43 to rotate. Since the gear 43 and the rack 42 are meshed with each other, and the driving motor 41 is fixedly installed, the rotation of the flushing fan blade 2 can be realized, and the roller 45 can be driven to travel on the guide rail 44, thereby realizing the synchronous rotation of the nozzle 22 driven by the flushing fan blade 2 when the flushing fan blade 2 rotates. When the flushing fan blade 2 drives the nozzle 22 to move, under the action of the arc-shaped groove 6151, the angle between the nozzle 22 and the fixing plate 6 deflects. When the angle between the nozzle 22 and the fixing plate 6 deflects, the corrugated pipe 611 will elongate, and the rotating ring 614 will rotate within the fixing ring 613, and the nozzle 22 will rotate within the fixing ring 613, thereby realizing the swing of the nozzle 22, increasing the flushing area and flushing angle of the nozzle 22, so as to better flush the positive electrode tube and improve the flushing effect on the positive electrode tube.

[0050] When it is necessary to clean the nozzle 22, water is injected into the internal pipeline 21 through the water inlet via the flexible connecting pipe 3. Since the density of the lifting plate 51 and the lifting block 53 is less than that of water, the lifting plate 51 and the lifting block 53 float on the water surface. The lifting block 53 can better provide buoyancy for the lifting plate 51, so that the dredging needle 52 can be better separated from the nozzle 22. When the water inlet stops injecting water into the internal pipeline 21, the lifting plate 51 and the lifting block 53 descend, and the dredging needle 52 enters the nozzle 22 to dredge and block the nozzle 22, thereby preventing dust that has not been adsorbed by the positive electrode tube from entering the water outlet of the nozzle 22 and causing blockage. At the same time as opening and blocking the water outlet of the nozzle 22, the scale cleaning work at the water outlet of the nozzle 22 is completed, further improving the service life of the nozzle 22 and the flushing effect on the positive electrode tube.
