Description

Technical Field

[0001] This application relates to the technical field of industrial waste gas treatment, and in particular to an electrostatic dust removal device with spray dust suppression function. Background Art

[0002] Currently, industrial production generates a massive amount of industrial waste gas. If the large amounts of dust and other pollutants contained in this gas are directly released into the atmosphere, it will cause serious environmental pollution. Electrostatic precipitators, as an important industrial waste gas treatment technology, can effectively remove dust from waste gas, playing a crucial role in improving air quality and reducing pollutant emissions.

[0003] In past electrostatic precipitator applications, traditional electrostatic precipitators primarily relied on simple electric field structures to adsorb dust. Typically, an electric field was created inside the chamber, adsorbing dust from industrial waste gas onto the inner wall of the anode tube. Some devices lacked a reasonable airflow distribution design, resulting in uneven flow of industrial waste gas within the chamber, leading to low utilization of the electric field's effective area and impacting dust removal efficiency. Furthermore, most of these devices only had single-stage processing capabilities, making multi-stage electrostatic dust removal of industrial waste gas difficult. Due to their relatively simple structural design, they were ineffective at adsorbing fine dust particles, failing to achieve efficient and thorough dust removal. The lack of effective dust suppression measures meant that some residual dust could not be promptly removed after electrostatic adsorption, resulting in a certain amount of pollutants remaining in the emitted waste gas. Moreover, the dust adsorbed on the inner wall of the anode tube could not be effectively removed; excessive dust adsorption could lead to a decrease in voltage between the anode tube and the cathode wire, a reduction in secondary current, a decrease in corona power, and a decline in dust removal efficiency. In addition, the lack of multi-stage processing capabilities prevents these devices from treating industrial waste gas multiple times, limiting their dust removal efficiency and purification level.

[0004] In view of the above-mentioned technologies, it is necessary to propose an electrostatic dust removal device with spray dust suppression function to solve one of the above-mentioned technical problems. Summary of the Invention

[0005] To solve one of the above-mentioned technical problems, this application provides an electrostatic dust removal device with spray dust suppression function.

[0006] This application provides an electrostatic dust removal device with spray dust suppression function, which adopts the following technical solution: An electrostatic precipitator with spray dust suppression function includes: The enclosure consists of several enclosures arranged in combination, with guide pipes connecting the enclosures for multi-stage electrostatic dust removal of industrial waste gas. An electrostatic generator assembly includes a plurality of anode tubes disposed within the housing and cathode wires disposed within the anode tubes. When the anode tubes and cathode wires are energized, an electric field is generated, which adsorbs dust from industrial waste gas onto the inner wall of the anode tubes. The spray assembly includes a support frame mounted on the top of the housing, several hangers mounted on the support frame, and a spiral spray pipe mounted on the hangers. The spiral surface of the spiral spray pipe is provided with several spray holes, and a nozzle is provided at the head of the spiral spray pipe. The spiral spray pipe is positioned above the anode tube, and the nozzle is aimed at the inner wall of the anode tube to spray water.

[0007] By adopting the above technical solution, multiple boxes are arranged in combination and connected by guide pipes, allowing industrial waste gas to pass through each box sequentially for multi-stage electrostatic dust removal. Compared with single-stage dust removal, this method can more thoroughly remove dust from the waste gas and effectively improve dust removal efficiency. In the electrostatic generating component, an electric field is formed after the anode tube and cathode wire are energized. Based on the principle of electrostatic adsorption, negatively charged dust will be adsorbed onto the positively charged inner wall of the anode tube, thereby achieving the separation of dust and gas in the waste gas. The spiral spray pipe of the spray component is set above the anode tube, and the nozzle of the pipe head is aimed at the inner wall of the anode tube. At the same time, multiple spray holes are distributed on the spiral surface. This structure allows the nozzle to directly wash the adsorbed dust on the inner wall of the anode tube during spraying, and the spray holes on the spiral surface can also spray water onto the inner wall of the anode tube from multiple angles, expanding the spray range and enabling more comprehensive and efficient flushing of the dust adsorbed on the inner wall of the anode tube, thereby achieving the purpose of dust reduction.

[0008] Optionally, a cathode frame is provided inside the box corresponding to the upper and lower parts of the anode tube. The cathode frame is connected to the upper and lower ends of the cathode wire respectively, in order to maintain the flatness of the cathode wire in the vertical direction inside the anode tube.

[0009] By adopting the above technical solution, cathode frames are set above and below the anode tube inside the box, and connected to the upper and lower ends of the cathode wire respectively, which can fix the position of the cathode wire inside the anode tube. When industrial waste gas passes through the anode tube for dust removal, the cathode wire is easily affected by the airflow of the waste gas and may be deflected or bent. The setting of the cathode frame can effectively constrain the cathode wire, ensuring that it remains flat in the vertical direction, thereby ensuring the uniformity and stability of the electric field distribution. This allows the dust in the industrial waste gas to be more effectively adsorbed onto the inner wall of the anode tube, improving the dust removal efficiency and effect of the electrostatic precipitator.

[0010] Optionally, a tensioning assembly is provided on the cathode frame relative to the upper and lower ends of the cathode wire. The tensioning assembly includes a positioning frame disposed on the cathode frame and a sliding clamp block slidably disposed within the positioning frame. The sliding clamp block is used to clamp the upper and lower ends of the cathode wire respectively, and the tension of the cathode wire is adjusted by adjusting the position of the sliding block within the positioning frame.

[0011] By adopting the above technical solution, the positioning frame guides and limits the sliding clamp, allowing the sliding clamp to slide stably within the positioning frame. The sliding clamp holds the upper and lower ends of the cathode wire respectively. When the position of the sliding clamp within the positioning frame is adjusted, the distance between the two ends of the cathode wire can be flexibly changed, thereby adjusting the tension of the cathode wire. After adjustment, the sliding clamp is fixedly connected to the positioning frame with bolts. This ensures that the cathode wire maintains a suitable tension within the anode tube, guaranteeing the vertical flatness of the cathode wire within the anode tube. This is beneficial for the stable formation of the electric field, allowing dust in industrial waste gas to be more effectively adsorbed onto the inner wall of the anode tube, thus improving the dust removal efficiency and effect of the electrostatic precipitator.

[0012] Optionally, a cleaning assembly for cleaning the inner wall of the anode tube is also included. The cleaning assembly includes a stabilizing frame disposed at the top of the housing, several adjusting rods disposed below the stabilizing frame, and a cleaning scraper disposed at the lower end of the adjusting rods. A driving cylinder is disposed at the bottom of the stabilizing frame, and a connecting block is disposed at the output end of the driving cylinder. The connecting block is connected to the upper end of the adjusting rod. The adjusting rods at the connecting block are driven by the output end of the driving cylinder to clean the inner wall of the anode tube using the cleaning scraper.

[0013] By adopting the above technical solution, the cleaning component can effectively clean the inner wall of the anode tube. Specifically, the stabilizing frame is installed at the top of the housing to provide stable support for the entire cleaning component. The adjusting rod is located below the stabilizing frame, and the cleaning scraper at its lower end can directly act on the inner wall of the anode tube. When cleaning is required, the drive cylinder at the bottom of the stabilizing frame operates, and its output end drives the connecting block to move. Since the connecting block is connected to the upper end of the adjusting rod, the movement of the connecting block will drive the adjusting rod to move, thereby causing the cleaning scraper to move up and down inside the anode tube, scraping away and cleaning the dust and impurities adsorbed on the inner wall of the anode tube, keeping the inner wall of the anode tube clean, and improving the dust removal efficiency and service life of the electrostatic precipitator.

[0014] Optionally, the cleaning scraper is provided with a cavity, and a spray hole is provided through the outer surface of the cleaning scraper corresponding to the cavity. A conduit is provided through the upper part of the cleaning scraper, and an extension hose is provided at the upper end of the conduit. The extension hose passes through the housing and is used to connect to an external cleaning water source.

[0015] By adopting the above technical solution, clean water is delivered through an external source and then through an extension hose to a conduit before entering the cavity of the cleaning scraper. Since the outer surface of the cleaning scraper is provided with spray holes corresponding to the cavity, the clean water can be sprayed out from the spray holes. Thus, during the cleaning process of the cleaning scraper cleaning the inner wall of the anode tube, the clean water can more effectively dissolve and clean the stubborn dust and impurities attached to the inner wall of the anode tube, thereby improving the cleaning effect and quality of the inner wall of the anode tube.

[0016] Optionally, a waste liquid collection tank is provided at the lower end of the interior of the box, and a discharge pipe is provided on the exterior of the box corresponding to the waste liquid collection tank. A concave surface is provided inside the waste liquid collection tank, and the concave surface is provided at the connection between the discharge pipe and the waste liquid collection tank.

[0017] By adopting the above technical solution, dust-laden waste liquid is generated during the operation of the electrostatic precipitator through spraying. The waste liquid collection tank set inside the tank can collect this waste liquid in a centralized manner. The concave surface set inside the waste liquid collection tank can guide the waste liquid to naturally converge at the connection between the discharge pipe and the waste liquid collection tank. Utilizing the principle that liquids flow to lower places due to gravity, the waste liquid flows more smoothly into the discharge pipe, thereby achieving effective discharge of the waste liquid and avoiding the accumulation of waste liquid in the tank, which would affect the normal operation of the device.

[0018] Optionally, a uniform distribution plate is provided inside the box below the anode tube, and industrial waste gas is guided to the anode tube for dust removal through the uniform distribution plate.

[0019] By adopting the above technical solution, when industrial waste gas passes through the uniform distribution plate, the plate can distribute the waste gas more evenly, thereby stably and evenly guiding the waste gas into the anode tube. This allows all parts of the anode tube to effectively participate in the adsorption of dust in the waste gas, improving the efficiency and effect of electrostatic dust removal, ensuring that the waste gas is fully treated, and reducing the situation where dust in the waste gas is directly discharged without being treated.

[0020] Optionally, the inner walls of the housing are provided with support frames on both sides, and elastic elements are provided at the upper and lower ends of the inner walls of the support frames. Support plates are provided at the ends of the elastic elements. The two sides of the uniform distribution plate are respectively inserted into the inner side of the support frames, and the upper and lower sides of the uniform distribution plate are connected to the support plates. A vibrator is provided on the uniform distribution plate to vibrate the uniform distribution plate and prevent the through holes on the uniform distribution plate from being blocked by dust in the exhaust gas.

[0021] By adopting the above technical solution, when the vibrator is working, the elastic element can be stretched and deformed, allowing the uniform distribution plate to vibrate flexibly within a certain range. This vibration can effectively prevent dust in the exhaust gas from accumulating at the through holes of the uniform distribution plate for a long time, thereby preventing the through holes on the uniform distribution plate from being blocked by dust in the exhaust gas, and ensuring that the industrial exhaust gas can be smoothly guided through the uniform distribution plate to the anode tube for dust removal.

[0022] Optionally, a baffle plate is provided at the top of the housing corresponding to the conveying pipe to disperse the exhaust gas and reduce the impact of the exhaust gas on the interior of the next-level housing.

[0023] By adopting the above technical solution, when the exhaust gas enters the next stage box through the guide pipe, the guide plate can change the flow direction and path of the exhaust gas, so that the exhaust gas is evenly dispersed, avoiding the exhaust gas from concentrating and impacting a certain area inside the next stage box. This effectively reduces the impact force of the exhaust gas on the inside of the next stage box, reduces the possibility of damage to the internal structure of the box caused by the exhaust gas impact, and ensures the stable operation of the device.

[0024] Optionally, the housing is provided with a tube frame for supporting a plurality of anode tubes, and the sides of the tube frame are provided with limiting blocks for external limiting support of the anode tubes to prevent the anode tubes from shaking due to exhaust gas impact within the housing.

[0025] By adopting the above technical solution, when industrial waste gas enters the chamber, it will generate an impact force. If the anode tube is not effectively supported and limited, it will easily shake due to the impact of the waste gas, affecting the stability of the electric field inside the anode tube and thus reducing the adsorption effect on dust. However, through the support of the tube frame and the limiting support of the surrounding side blocks, it can be ensured that the anode tube remains stable in the chamber and will not shake due to the impact of the waste gas, thereby ensuring the stable operation of the electric field, improving the adsorption efficiency of dust in industrial waste gas, and extending the service life of the equipment.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Multiple boxes are arranged in combination and equipped with guide pipes to carry out multi-stage electrostatic dust removal of industrial waste gas, which significantly improves dust removal efficiency and purification level; the spray assembly uses spiral spray pipes and nozzles to spray the inner wall of the anode tube, quickly remove the dust adsorbed on the inner wall of the anode tube, and realize the dust reduction function. 2. The drive cylinder of the cleaning component drives the adjusting rod and the cleaning scraper to clean the inner wall of the anode tube, which can further remove dust from the inner wall of the anode tube; the cavity and spray hole of the cleaning scraper, together with the cleaning agent supply box and other structures, can use the cleaning agent to assist in cleaning the inner wall of the anode tube, thereby improving the cleaning effect; 3. The uniform distribution plate can evenly guide industrial waste gas into the anode tube for dust removal, improve the utilization rate of the electric field area, and enhance the dust removal effect; the support frame is inserted on both sides of the uniform distribution plate, and its upper and lower surfaces are connected to the support plate. The vibrator on the uniform distribution plate can vibrate the uniform distribution plate to avoid the through holes on the uniform distribution plate being blocked by dust in the waste gas.

Detailed Implementation

[0038] The following is in conjunction with the accompanying drawings. Figures 1-10 This application will be described in further detail.

[0039] Example 1, Reference Figures 1-4 This application discloses an electrostatic dust removal device with spray dust suppression function, including: a housing 1, an electrostatic generating component 2 and a spraying component 3.

[0040] The chamber 1 consists of several units arranged in combination, with guide pipes 11 connecting them for multi-stage electrostatic dust removal of industrial waste gas. The electrostatic generating component 2 includes several anode tubes 21 and cathode wires 22 installed inside the anode tubes 21. When the anode tubes 21 and cathode wires 22 are energized, an electric field is generated, which adsorbs dust from the industrial waste gas onto the inner wall of the anode tubes 21. The spraying component 3 includes a support frame 31 installed at the top of the chamber 1, several hanging rods 32 installed on the support frame 31, and spiral spray pipes 33 installed on the hanging rods 32. The spiral surface of the spiral spray pipes 33 is provided with several spray holes 34, and a nozzle 35 is installed at the head of the spiral spray pipes 33. The spiral spray pipes 33 are positioned above the anode tubes 21, and the nozzles 35 spray the inner wall of the anode tubes 21.

[0041] Multiple housings 1 are arranged in combination and connected by guide pipes 11, allowing industrial waste gas to pass through each housing 1 sequentially for multi-stage electrostatic dust removal. Compared with single-stage dust removal, this method can more thoroughly remove dust from the waste gas and effectively improve dust removal efficiency. In the electrostatic generating component 2, an electric field is formed after the anode tube 21 and cathode wire 22 are energized. Based on the principle of electrostatic adsorption, negatively charged dust particles are adsorbed onto the inner wall of the positively charged anode tube 21, thereby achieving the separation of dust and gas in the waste gas. The spray component 3 has a spiral spray pipe. The nozzle 33 is positioned above the anode tube 21, with the nozzle 35 aligned with the inner wall of the anode tube 21. Multiple spray holes 34 are distributed on the spiral surface. This structure allows the nozzle 35 to directly wash away the adsorbed dust on the inner wall of the anode tube 21 during spraying, while the spray holes 34 on the spiral surface can also spray water onto the inner wall of the anode tube 21 from multiple angles, expanding the spraying range and enabling a more comprehensive and efficient flushing of the dust adsorbed on the inner wall of the anode tube 21, thereby achieving dust reduction.

[0042] refer to Figure 1 In this embodiment, more specifically, a cathode frame 23 is provided above and below the anode tube 21 inside the box. The cathode frame 23 is connected to the upper and lower ends of the cathode wire 22 respectively, and is used to maintain the vertical flatness of the cathode wire 22 inside the anode tube 21. The cathode frame 23 is provided above and below the anode tube 21 inside the box and is connected to the upper and lower ends of the cathode wire 22 respectively, which can fix the position of the cathode wire 22 inside the anode tube 21. When industrial waste gas is removed from dust through the anode tube 21, the cathode wire 22 is easily affected by the airflow of the waste gas and may be deflected or bent. The cathode frame 23 can effectively constrain the cathode wire 22 and ensure that it always remains flat in the vertical direction, thereby ensuring the uniformity and stability of the electric field distribution, so that the dust in the industrial waste gas can be more effectively adsorbed to the inner wall of the anode tube 21, and improving the dust removal efficiency and effect of the electrostatic precipitator.

[0043] refer to Figure 1 In this embodiment, more specifically, a waste liquid collection tank 12 is provided at the lower end of the inner side of the housing 1, and a discharge pipe 13 is provided on the outside of the housing 1 corresponding to the waste liquid collection tank 12. A concave surface 14 is provided inside the waste liquid collection tank 12, and the concave surface 14 is provided at the connection between the discharge pipe 13 and the waste liquid collection tank 12. During the operation of the electrostatic dust removal device, dust-containing waste liquid will be generated after spraying. The waste liquid collection tank 12 provided inside the housing 1 can collect this waste liquid in a concentrated manner. The concave surface 14 provided inside the waste liquid collection tank 12 can guide the waste liquid to naturally converge at the connection between the discharge pipe 13 and the waste liquid collection tank 12. By utilizing the principle that liquids flow to lower places under the action of gravity, the waste liquid can flow more smoothly into the discharge pipe 13, thereby achieving effective discharge of waste liquid and avoiding the accumulation of waste liquid in the housing 1, which would affect the normal operation of the device.

[0044] refer to Figure 1In this embodiment, more specifically, a uniform distribution plate 15 is provided below the anode tube 21 inside the housing 1. Industrial waste gas is guided to the anode tube 21 for dust removal through the uniform distribution plate 15. When the industrial waste gas passes through the uniform distribution plate 15, the uniform distribution plate 15 can make the waste gas more evenly distributed, thereby stably and evenly guiding the waste gas to the anode tube 21. This allows all parts inside the anode tube 21 to effectively participate in the adsorption of dust in the waste gas, improving the efficiency and effect of electrostatic dust removal, ensuring that the waste gas can be fully treated, and reducing the situation where dust in the waste gas is directly discharged without being treated.

[0045] refer to Figure 10 In this embodiment, more specifically, support frames 6 are provided on both sides of the inner wall of the housing 1. Elastic members 61 are provided at the upper and lower ends of the inner side of the support frames 6. Support plates 62 are provided at the ends of the elastic members 61. The two sides of the uniform distribution plate 15 are respectively inserted into the inner side of the support frames 6, and the upper and lower sides of the uniform distribution plate 15 are connected to the support plates 62. A vibrator 7 is provided on the uniform distribution plate 15 to vibrate the uniform distribution plate 15 and prevent the through holes on the uniform distribution plate 15 from being blocked by dust in the exhaust gas. When the vibrator 7 is working, the elastic member 61 is a spring. Utilizing the stretchable and deformable characteristics of the elastic member 61, the uniform distribution plate 15 can vibrate flexibly within a certain range. This vibration can effectively prevent dust in the exhaust gas from accumulating at the through holes of the uniform distribution plate 15 for a long time, thereby preventing the through holes on the uniform distribution plate 15 from being blocked by dust in the exhaust gas, and ensuring that the industrial exhaust gas can be smoothly guided through the uniform distribution plate 15 to the anode tube 21 for dust removal.

[0046] refer to Figure 1 In this embodiment, more specifically, a baffle plate 16 is provided at the top of the housing 1 corresponding to the guide pipe 11 to disperse exhaust gas and reduce the impact of exhaust gas on the interior of the next-level housing 1. When exhaust gas enters the next-level housing 1 through the guide pipe 11, the baffle plate 16 can change the flow direction and path of the exhaust gas, so that the exhaust gas is evenly dispersed, avoiding the exhaust gas from concentrating on impacting a certain area inside the next-level housing 1. This effectively reduces the impact force of exhaust gas on the interior of the next-level housing 1, reduces the possibility of damage to the internal structure of the housing 1 caused by exhaust gas impact, and ensures the stable operation of the device.

[0047] refer to Figure 1 and Figure 2In this embodiment, more specifically, the housing 1 is provided with a tube frame 24 for supporting several anode tubes 21. The sides of the tube frame 24 are provided with limiting blocks 25 for external limiting support of the anode tubes 21, so as to prevent the anode tubes 21 from shaking due to the impact of exhaust gas in the housing 1. When industrial exhaust gas enters the housing 1, it will generate an impact force. If the anode tubes 21 are not effectively supported and limited, they are easy to shake due to the impact of exhaust gas, which will affect the stability of the electric field in the anode tubes 21 and thus reduce the adsorption effect on dust. However, through the support of the tube frame 24 and the limiting support of the limiting blocks 25 on the sides, it can be ensured that the anode tubes 21 remain stable in the housing 1 and will not shake due to the impact of exhaust gas, thereby ensuring the stable operation of the electric field, improving the adsorption efficiency of dust in industrial exhaust gas, and extending the service life of the equipment.

[0048] The implementation principle of an electrostatic dust removal device with spray dust suppression function in this application embodiment is as follows: multiple boxes 1 are combined and connected with a guide pipe 11 to realize multi-stage electrostatic dust removal of industrial waste gas. The electrostatic generating component 2 generates an electric field to adsorb dust. The spray component 3 sprays the dust in the waste gas and washes the inner wall of the anode tube 21 so as to collect the dust in the waste gas. The uniform distribution plate 15 makes the waste gas flow evenly. The guide plate 16 optimizes the flow path of the waste gas. The pipe frame 24 and the limiting support ensure the stability of the anode tube 21. These combined effects improve the dust removal efficiency and purification degree of industrial waste gas.

[0049] Example 2, reference Figure 5 and Figure 6 The difference between this embodiment and Embodiment 1 is that a tensioning assembly 4 is provided on the cathode frame 23 at the upper and lower ends relative to the cathode wire 22. The tensioning assembly 4 includes a positioning frame 41 on the cathode frame 23 and a sliding clamp 42 slidably disposed within the positioning frame 41. The sliding clamp 42 is used to clamp the upper and lower ends of the cathode wire 22 respectively, and the tension of the cathode wire 22 is adjusted by adjusting the position of the sliding block within the positioning frame 41. The positioning frame 41 guides and limits the sliding clamp 42, allowing the sliding clamp 42 to slide stably within the positioning frame 41. The sliding clamp 42 provides tension for the cathode wire 22. The upper and lower ends are clamped respectively. When the position of the sliding clamp 42 in the positioning frame 41 is adjusted, the distance between the two ends of the cathode wire 22 can be flexibly changed, thereby adjusting the tension of the cathode wire 22. After adjustment, the sliding clamp 42 is positioned and connected to the positioning frame 41 by bolts. This ensures that the cathode wire 22 always maintains a suitable tension in the anode tube 21, and ensures the flatness of the cathode wire 22 in the vertical direction in the anode tube 21. This is conducive to the stable formation of the electric field, so that the dust in the industrial waste gas can be more effectively adsorbed to the inner wall of the anode tube 21, thereby improving the dust removal efficiency and effect of the electrostatic precipitator.

[0050] Example 3, reference Figure 7-Figure 9The difference between this embodiment and Embodiment 1 is that it also includes a cleaning assembly 5 for cleaning the inner wall of the anode tube 21. The cleaning assembly 5 includes a stabilizing frame 51 located at the top of the housing 1, several adjusting rods 52 located below the stabilizing frame 51, and a cleaning scraper 53 located at the lower end of each adjusting rod 52. A driving cylinder 54 is located at the bottom of the stabilizing frame 51, and a connecting block 55 is located at the output end of the driving cylinder 54. The connecting block 55 is connected to the upper end of each adjusting rod 52. The driving cylinder 54 drives the adjusting rods 52 at the connecting block 55 to clean the inner wall of the anode tube 21 using the cleaning scraper 53. A groove 59 is located on one side of the connecting block 55, which is used for the cathode wire 22 to pass through, preventing damage to the cathode wire 22 during adjustment of the connecting block 55. The cleaning assembly 5 effectively cleans the inner wall of the anode tube 21. Specifically, the stabilizing frame 51 is installed at the top of the housing 1, providing stable support for the entire cleaning assembly 5. The adjusting rod 52 is located below the stabilizing frame 51, and the cleaning scraper 53 at its lower end can directly act on the inner wall of the anode tube 21. When cleaning is required, the drive cylinder 54 at the bottom of the stabilizing frame 51 works, and its output end drives the connecting block 55 to move. Since the connecting block 55 is connected to the upper end of the adjusting rod 52, the movement of the connecting block 55 will drive the adjusting rod 52 to move, thereby causing the cleaning scraper 53 to move up and down inside the anode tube 21, scraping away and cleaning the dust and impurities adsorbed on the inner wall of the anode tube 21, keeping the inner wall of the anode tube 21 clean, and improving the dust removal efficiency and service life of the electrostatic precipitator.

[0051] refer to Figure 8 and Figure 9 In this embodiment, more specifically, the cleaning scraper 53 is provided with a cavity, and a spray hole 56 is provided through the cavity on the outer surface of the cleaning scraper 53. A conduit 57 is provided through the upper part of the cleaning scraper 53, and an extension hose 58 is provided at the upper end of the conduit 57. The extension hose 58 passes through the housing 1 and is used to connect to an external cleaning water source. The cleaning water is transported through the external cleaning water source and through the extension hose 58 to the conduit 57, and then enters the cavity of the cleaning scraper 53. Since the spray hole 56 is provided through the cavity on the outer surface of the cleaning scraper 53, the cleaning water source can be sprayed out from the spray hole 56. Thus, during the cleaning process of the cleaning scraper 53 cleaning the inner wall of the anode tube 21, the cleaning water source can be used to more effectively dissolve and clean the stubborn dust and impurities attached to the inner wall of the anode tube 21, thereby improving the cleaning effect and quality of the inner wall of the anode tube 21.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
