Description

Technical Field

[0001] This utility model relates to the field of electrostatic precipitator technology, and specifically to a cleaning device for an electrostatic precipitator. Background Technology

[0002] Electrostatic precipitators primarily charge dust particles through discharge in the cathode system (electrode wires), which are then adsorbed and captured in the electric field formed by the anode system (plates). Their efficient and stable operation largely depends on the cleanliness of the electrode wires and plates. However, in practical industrial applications, when handling dust with high resistivity or a certain degree of stickiness, this dust tends to adhere firmly to the electrode plates. If the electrostatic precipitator operates under high load for extended periods, the dust on the plates may clump or condense, forming a difficult-to-remove dust layer. This dust layer hinders the smooth conduction of current, causing charge to accumulate within the dust layer, resulting in a back corona phenomenon (i.e., surface discharge of the dust layer). This not only weakens the collecting electric field strength but also causes secondary dust backflow, significantly reducing dust removal efficiency.

[0003] Currently, the traditional method for solving the problem of dust accumulation on electrode plates and wires mainly relies on manual cleaning.

[0004] A common method is manual tapping, where workers enter the dust collector and physically tap to dislodge the dust. However, this method suffers from uneven dust removal; the closer to the tapping point, the better the dust removal, while areas farther away are less effective, resulting in incomplete dust removal.

[0005] Another method is to use a high-pressure water gun for rinsing. Although the cleaning power is strong, the working cycle is long and the cost is high. In addition, the water flow can easily cause oxidation and rust on the electrode plates and wires, affecting their conductivity and service life.

[0006] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0007] The purpose of this invention is to provide a cleaning device for an electrostatic precipitator.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A cleaning device for an electrostatic precipitator, wherein the electrostatic precipitator is provided with a plurality of parallel and spaced plate-wire mechanisms, each plate-wire mechanism including an electrode wire and an electrode plate fixedly connected within the electrostatic precipitator, the electrode plate having an adsorption surface opposite to the electrode wire, the cleaning device being configured to clean the plate-wire mechanisms, the cleaning device including a lateral movement mechanism and a cleaning mechanism.

[0010] The lateral moving mechanism is movably connected to the top edge of the adsorption surface of the electrode plate. The lateral moving mechanism is configured to move along a first direction, which is parallel to the lateral direction of the electrode plate. The lateral moving mechanism has a driving member, and a connecting member is provided on the working end of the driving member. The end of the connecting member is suspended beside the adsorption surface. The suspended end of the connecting member is configured to be driven by the driving member to move along a second direction, which is perpendicular to the first direction. The plane formed by the second direction and the first direction is parallel to the adsorption surface.

[0011] The cleaning mechanism is provided corresponding to the adsorption surface, and the cleaning mechanism is positioned and connected to the suspension end of the connector. A cleaning wheel is rotatably provided on the cleaning mechanism. The peripheral surface of the cleaning wheel abuts against the adsorption surface. The cleaning wheel is configured to actively rotate around its own axis to rotate and clean the adsorption surface.

[0012] Specifically, when the lateral moving mechanism moves along the first direction, it drives the cleaning mechanism to move synchronously. The driving component, through the connecting component, pushes the sweeping wheel to reciprocate along the second direction, causing the sweeping wheel to form a longitudinal cleaning path on the adsorption surface. In other words, the lateral moving mechanism is first driven to move along the first direction to determine the position of the sweeping wheel on the adsorption surface. Then, the driving component pulls the connecting component to move, causing the sweeping wheel to reciprocate along the second direction, thus completing a horizontal and vertical interwoven cleaning trajectory on the adsorption surface, achieving thorough cleaning. Throughout this process, the sweeping wheel remains in close contact with the adsorption surface, ensuring that dust particles are effectively removed while preventing secondary adhesion.

[0013] Unlike traditional rapping cleaning and fixed spray cleaning methods, this solution achieves two-dimensional planar cleaning path coverage of the cleaning wheel on the adsorption surface through the coordinated control of the lateral movement mechanism and the drive component. Moreover, the movement trajectory of the cleaning wheel can be adjusted according to the degree of contamination on the adsorption surface. Its cleaning efficiency is higher than that of rapping cleaning, while avoiding the problems of water residue and equipment corrosion caused by spray cleaning.

[0014] In a further technical solution, the lateral movement mechanism includes a fixed frame, on which a roller connected to the output end of the motor is mounted, and a rope is wound around the periphery of the roller;

[0015] The driving component is a roller that is positioned and connected to the output end of the motor, and the connecting component is a rope winding device.

[0016] Since the combination of screw and sleeve cannot be adapted to electrode plates of different sizes, the above design allows the cleaning mechanism to be adapted to electrode plates of different sizes. That is, the range of movement of the cleaning mechanism in the second direction can be flexibly adjusted by the length of the winding rope.

[0017] In a further technical solution, the axis of the roller extends parallel to the first direction.

[0018] A further technical solution is that the cleaning mechanism includes a mounting frame, on which a plurality of magnetic rings are provided on one side corresponding to the adsorption surface, and each magnetic ring has a rolling wheel at both ends. The magnetic ring and the rolling wheel are coaxially arranged and have the same diameter.

[0019] Furthermore, a cleaning wheel is provided on one side of the mounting frame corresponding to the adsorption surface. The cleaning wheel abuts against the adsorption surface through the magnetic attraction between the magnetic ring and the adsorption surface of the electrode plate.

[0020] With the above design, the magnetic ring can automatically adhere to and press firmly against the adsorption surface, ensuring that the sweeping wheel maintains stable contact with the adsorption surface during movement, thereby improving the reliability and consistency of cleaning.

[0021] In a further technical solution, the axis of the sweeping wheel extends parallel to the first direction.

[0022] The above design allows the sweeping wheel to fully conform to the suction surface, ensuring that there are no blind spots in the cleaning process.

[0023] A further technical solution is that a cleaning brush acting on the pole line is positioned and connected on the side of the mounting frame opposite to the side where the cleaning wheel is located, and the extension line of the cleaning brush in the length direction is parallel to the axis of the cleaning wheel.

[0024] The above design is used to clean the polar lines using a cleaning brush.

[0030] The working principle and advantages of this utility model are as follows:

[0031] In this invention, the cleaning wheel can fully clean the adsorption surface through the cooperation of the lateral movement mechanism, the driving component, the connecting component, and the cleaning mechanism.

[0032] Specifically, when the lateral moving mechanism moves along the first direction, it drives the cleaning mechanism to move synchronously. The driving component, through the connecting component, pushes the sweeping wheel to reciprocate along the second direction, causing the sweeping wheel to form a longitudinal cleaning path on the adsorption surface. In other words, the lateral moving mechanism is first driven to move along the first direction to determine the position of the sweeping wheel on the adsorption surface. Then, the driving component pulls the connecting component to move, causing the sweeping wheel to reciprocate along the second direction, thus completing a horizontal and vertical interwoven cleaning trajectory on the adsorption surface, achieving thorough cleaning. Throughout this process, the sweeping wheel remains in close contact with the adsorption surface, ensuring that dust particles are effectively removed while preventing secondary adhesion.

[0033] Unlike traditional rapping cleaning and fixed spray cleaning methods, this solution achieves two-dimensional planar cleaning path coverage of the cleaning wheel on the adsorption surface through the coordinated control of the lateral movement mechanism and the drive component. Moreover, the movement trajectory of the cleaning wheel can be adjusted according to the degree of contamination on the adsorption surface. Its cleaning efficiency is higher than that of rapping cleaning, while avoiding the problems of water residue and equipment corrosion caused by spray cleaning. Attached Figure Description

[0043] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0044] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0045] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0046] See appendix Figure 1 - Figure 5 As shown, a cleaning device for an electrostatic precipitator is provided. The electrostatic precipitator is provided with a plurality of parallel and spaced plate-line mechanisms 1. Each plate-line mechanism 1 includes an electrode wire 11 and an electrode plate 12 fixedly connected inside the electrostatic precipitator. The electrode plate 12 has an adsorption surface 121 opposite to the electrode wire 11. The cleaning device is configured to clean the plate-line mechanism 1. The cleaning device includes a lateral movement mechanism 2 and a cleaning mechanism 3.

[0047] The lateral moving mechanism 2 is movably connected to the top edge of the adsorption surface 121 of the electrode plate 12. The lateral moving mechanism 2 is configured to move along a first direction 21, which is parallel to the lateral direction of the electrode plate 12. The lateral moving mechanism 2 has a driving member 22. The working end of the driving member 22 is provided with a connecting member 23. The end of the connecting member 23 is suspended on the side of the adsorption surface 121. The suspended end of the connecting member 23 is configured to be driven by the driving member 22 to move along a second direction 24, which is perpendicular to the first direction 21. The plane formed by the second direction 24 and the first direction 21 is parallel to the adsorption surface 121.

[0048] The cleaning mechanism 3 is provided corresponding to the adsorption surface 121, and the cleaning mechanism 3 is positioned and connected to the suspension end of the connector 23. A cleaning wheel 31 is rotatably provided on the cleaning mechanism 3. The peripheral surface of the cleaning wheel 31 abuts against the adsorption surface 121. The cleaning wheel 31 is configured to actively rotate around its own axis to rotate and clean the adsorption surface 121.

[0049] In this invention, the adsorption surface 121 is generally rectangular. Therefore, the transverse moving mechanism 2 is set at the upper end of the electrode plate 12 and moves along the length of the electrode plate 12.

[0050] In this invention, the cooperation between the driving component 22 and the connecting component 23 can be a combination of a motor and a rope, or a combination of a screw and a sliding sleeve.

[0051] Wherein, the first direction 21 is the transverse direction of the electrode 12, that is, the length direction of the electrode 12, and the second direction 24 is the width direction of the electrode 12, which can be referred to as... Figure 2 .

[0052] In this invention, the axis of the sweeping wheel 31 is generally chosen to be parallel to the adsorption surface 121, and the extension direction of the axis of the sweeping wheel 31 is also parallel to the first direction 21. This ensures that the sweeping wheel 31 cleans only the area that its circumferential surface can contact. Compared to a scenario where the extension direction of the axis of the sweeping wheel 31 intersects the first direction 21 at a set angle (i.e., the sweeping wheel 31 is not horizontal but inclined), this effectively avoids blind spots caused by the inclined setting, ensuring that accumulated dust on the adsorption surface 121 is completely removed, thus improving cleaning efficiency and dust removal effect. Furthermore, the horizontally positioned sweeping wheel 31 experiences more even force, reducing wear during operation and extending its service life.

[0053] In this invention, the cleaning wheel 31 can fully clean the adsorption surface 121 by cooperating with the lateral moving mechanism 2, the driving component 22, the connecting component 23 and the cleaning mechanism 3.

[0054] Specifically, when the lateral moving mechanism 2 moves along the first direction 21, it drives the cleaning mechanism 3 to move synchronously. The driving component 22, through the connecting component 23, pushes the sweeping wheel 31 to reciprocate along the second direction 24, causing the sweeping wheel 31 to form a longitudinal cleaning path on the adsorption surface 121. In other words, the lateral moving mechanism 2 is first driven to move along the first direction 21 to determine the position of the sweeping wheel 31 on the adsorption surface 121. Then, the driving component 22 pulls the connecting component 23 to move, causing the sweeping wheel 31 to reciprocate along the second direction 24, thereby completing a horizontal and vertical interwoven cleaning trajectory on the adsorption surface 121, achieving thorough cleaning. During this process, the sweeping wheel 31 always remains in close contact with the adsorption surface 121, ensuring that dust particles are effectively removed while preventing secondary adhesion.

[0055] Unlike traditional vibration cleaning and fixed spray cleaning methods, this solution achieves two-dimensional planar cleaning path coverage of the sweeping wheel 31 on the adsorption surface 121 through the coordinated control of the lateral moving mechanism 2 and the driving component 22. Moreover, the movement trajectory of the sweeping wheel 31 can be adjusted according to the degree of contamination of the adsorption surface 121. Its cleaning efficiency is higher than that of vibration cleaning, while avoiding the problems of water residue and equipment corrosion caused by spray cleaning.

[0056] Preferably, the lateral moving mechanism 2 includes a fixed frame 25, on which a roller is mounted and positioned and connected to the output end of the motor, and a rope is wound around the periphery of the roller;

[0057] The driving component 22 is a roller that is positioned and connected to the output end of the motor, and the connecting component 23 is a rope winding component.

[0058] Since the combination of screw and sleeve cannot be adapted to electrode plates 12 of different sizes, the above design allows the cleaning mechanism 3 to be adapted to electrode plates 12 of different sizes. That is, the range of movement of the cleaning mechanism 3 in the second direction 24 can be flexibly adjusted by the length of the winding rope.

[0059] Preferably, the axis of the roller extends parallel to the first direction 21.

[0060] With the above design, the radial circumference of the roller will not extend too far beyond the adsorption surface 121. If the roller's axis extends perpendicularly to the first direction 21, it means the roller is set perpendicular to the adsorption surface 121. In this case, the winding rope cannot effectively pull the sweeping wheel 31 close to the adsorption surface 121, thus affecting the adhesion between the sweeping wheel 31 and the adsorption surface 121. By setting the roller's axis parallel to the first direction 21, the winding rope is tilted when being wound and unwound on the roller, such as... Figure 1 This is because the sweeping wheel 31 protrudes from the adsorption surface 121, and when the rope is wound up and down, it guides the sweeping wheel 31 to further adhere to the adsorption surface 121.

[0061] If the roller is set perpendicular to the adsorption surface 121, the sweeping wheel 31 may collide or lose contact with the adsorption surface 121 if the winding rope shakes during winding and unwinding.

[0062] Preferably, the cleaning mechanism 3 includes a mounting frame 32, on which a plurality of magnetic rings 33 are provided on one side corresponding to the adsorption surface 121. Each magnetic ring 33 has a rolling wheel 35 at both ends. The magnetic ring 33 and the rolling wheel 35 are coaxially arranged and have the same diameter.

[0063] Furthermore, a cleaning wheel 31 is provided on one side of the mounting frame 32 corresponding to the adsorption surface 121. The cleaning wheel 31 abuts against the adsorption surface 121 through the magnetic attraction between the magnetic ring 33 and the adsorption surface 121 of the electrode plate 12.

[0064] With the above design, the magnetic rings 33 can automatically adhere to and press firmly against the adsorption surface 121 through their adsorption force, ensuring that the cleaning wheel 31 maintains stable contact with the adsorption surface 121 during movement, thereby improving the reliability and consistency of cleaning. Simultaneously, the rolling wheel 35 rotates synchronously with the magnetic rings 33, effectively reducing movement resistance and preventing scratches on the adsorption surface 121. Multiple magnetic rings 33 are evenly distributed along the mounting frame 32, adapting to adsorption surfaces 121 of different areas and enhancing the versatility of the device.

[0065] Preferably, the axis of the sweeping wheel 31 extends parallel to the first direction 21.

[0066] With the above design, the sweeping wheel 31 can fully fit the adsorption surface 121, so that there are no blind spots in the cleaning of the sweeping wheel 31.

[0067] In a further technical solution, a cleaning brush 34 acting on the pole line 11 is positioned and connected on the side of the mounting frame 32 opposite to the side where the cleaning wheel 31 is located, and the extension line of the cleaning brush 34 in the length direction is parallel to the axis of the cleaning wheel 31.

[0068] The above design is used to clean the polar line 11 by sweeping brush 34.

[0069] Working principle:

[0070] First, the mounting bracket 25 is moved along the first direction 21. As the mounting bracket 25 moves, the mounting frame 32 is moved along with the winding rope until the cleaning wheel 31 is in the appropriate position. Then, the cleaning wheel 31, magnetic ring 33, and rolling wheel 35 are guided to contact the adsorption surface 121. Subsequently, the rolling wheel is driven to rotate to release the winding rope. The cleaning wheel 31 then descends under the gravity of the mounting frame 32 and cleans the adsorption surface 121. After completing one cleaning cycle in the second direction 24 (for example, it can slide down to detach from the adsorption surface 121), the mounting bracket 25 can be moved again, allowing the cleaning wheel 31 to move to an uncleaned area of ​​the adsorption surface 121. The rolling wheel is then driven to rotate to rewind the winding rope, causing the cleaning wheel 31 to move upwards along the adsorption surface 121, re-adhering and pressing firmly against the adsorption surface 121, thus beginning the next cleaning cycle. By repeatedly rewinding and unwinding the winding rope, combined with the intermittent movement of the mounting bracket 25 in the first direction 21, full coverage cleaning of the entire adsorption surface 121 is achieved. The cleaning brush 34 moves synchronously with the mounting frame 32 to clean the electrode wire 11 in sync, improving overall cleaning efficiency.

[0071] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
