Description

Technical Field

[0001] This utility model relates to the technical field of electrostatic precipitator equipment, specifically to an electrostatic precipitator anode plate rapping cleaning system. Background Technology

[0002] Porous anode plates with internal cavities are a new type of dust-collecting electrode for electrostatic precipitators (ESPs). Compared with traditional anode plates, they have advantages such as higher efficiency and larger dust-collecting area, and are therefore gradually being used in the field of industrial ESPs. However, the traditional rapping method is not ideal for transmitting the rapping acceleration of this new type of anode plate, resulting in the ESP outlet concentration being much higher than the design value. As the final step in the ESP dust removal process, rapping cleaning determines the overall particulate matter concentration in the flue gas at the ESP outlet.

[0003] Existing rapping devices are typically installed at the bottom of the anode plate. They vibrate the bottom of the anode plate laterally, causing the adsorbed dust to fall downwards and be collected at the bottom for centralized cleaning. However, in existing equipment, because the vibration of the porous anode plate decays rapidly during rapping, dust on anode plates far from the bottom rapping device is not easily dislodged. Therefore, the current design has poor dust removal efficiency for anode plates far from the lower rapping device. Furthermore, existing designs generally use dust thickness sensors to detect the thickness of dust adhering to the anode plate surface. When the thickness reaches a set value, the rapping device is activated. However, because the dust thickness sensor is exposed to a dusty environment, it is prone to damage, and the dust distribution is often uneven, leading to inaccurate dust thickness readings and ultimately, ineffective dust removal from the anode plate.

[0004] In summary, there is an urgent need for an electrostatic precipitator anode plate rapping cleaning system to solve or at least partially solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a vibratory cleaning system for anode plates of electrostatic precipitators, aiming to solve the technical problem of poor cleaning effect in existing vibratory cleaning devices for anode plates. The specific technical solution is as follows:

[0006] An electrostatic precipitator anode plate rapping cleaning system includes a support frame, a first rapping mechanism, a second rapping mechanism, a first transmission rod, and a second transmission rod. The first transmission rod is installed on the top of the anode plate, and the second transmission rod is installed on the bottom of the anode plate. The first rapping mechanism is mounted on the support frame and is arranged opposite to the first transmission rod on the top of the support frame, so that the first rapping mechanism rappels the first transmission rod. The second rapping mechanism is mounted on the support frame and is arranged opposite to the second transmission rod, so that the second rapping mechanism rappels the second transmission rod.

[0007] Furthermore, the first and second rapping mechanisms are arranged on the same side of the anode plate.

[0008] Furthermore, the first and second rapping mechanisms are respectively staggered and arranged on opposite sides of the anode plate.

[0009] Furthermore, the first transfer rod is arranged horizontally, and the second transfer rod is arranged horizontally.

[0010] Furthermore, it also includes a first vibrating anvil and a second vibrating anvil, the first vibrating anvil being fixedly connected to the first transmission rod and arranged at one end near the first vibrating mechanism; the second vibrating anvil being fixedly connected to the second transmission rod and arranged at one end near the second vibrating mechanism.

[0011] Furthermore, it also includes arc-shaped supports, with two arc-shaped supports arranged at the lower parts of both ends of the first transmission rod, and the two arc-shaped supports are arranged on the same axis; the first transmission rod is sway-supported on the support frame through the two arc-shaped supports.

[0012] Furthermore, it also includes a weight sensor, with two weight sensors arranged in a one-to-one correspondence between the two weight sensors and two arc-shaped supports. The first end of the weight sensor is connected to the first transmission rod, and the second end of the weight sensor is connected to the arc-shaped support. The first transmission rod, the weight sensor, and the arc-shaped support are arranged sequentially from top to bottom.

[0013] Furthermore, it also includes protective rubber sleeves, with two protective rubber sleeves arranged in a one-to-one correspondence between the two protective rubber sleeves and the two weight sensors. The protective rubber sleeves are arranged around the outside of the weight sensors, with the first end of the protective rubber sleeves fixedly connected to the first transmission rod and the second end of the protective rubber sleeves fixedly connected to the arc-shaped support.

[0014] Furthermore, it also includes a controller, the first end of which is connected to a weight sensor, the second end of which is connected to a first vibration mechanism, and the third end of which is connected to a second vibration mechanism.

[0015] Furthermore, it also includes an ash hopper, which is arranged directly below the anode plate.

[0016] The application of the technical solution of this utility model has the following beneficial effects:

[0017] The first vibration mechanism at the upper end of the anode plate vibrates the first transmission rod, transmitting the impact to the anode plate and causing it to vibrate. This causes the dust adhering to the upper end of the anode plate to fall downwards. Similarly, the second vibration mechanism at the lower end of the anode plate vibrates the second transmission rod, transmitting the impact to the anode plate and causing the dust adhering to the lower end to fall downwards. This combination of first and second vibration mechanisms ensures that dust on both the upper and lower ends of the anode plate is promptly removed under vibration, preventing back corona discharge and improving the cleaning effect.

[0018] In addition, the weight of the anode plate is measured in real time by a weight sensor. As dust gradually adheres to the anode plate, its weight slowly increases. The weight sensor converts the weight signal into a voltage signal and transmits it outward. The controller then controls the first and second rapping mechanisms to rappel and clean the dust from the anode plate.

[0019] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. These will be described below with reference to...

Detailed Implementation

[0026] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] Example 1:

[0029] See Figures 1-3 This embodiment provides a rapping cleaning system for an anode plate 13 of an electrostatic precipitator, including a support frame 1, a first rapping mechanism 2, a second rapping mechanism 3, a first transmission rod 4, and a second transmission rod 5. The first transmission rod 4 is installed on the top of the anode plate 13, and the second transmission rod 5 is installed on the bottom of the anode plate 13. The first rapping mechanism 2 is installed on the support frame 1, and is arranged opposite to the first transmission rod 4 and on the top of the support frame 1, so that the first rapping mechanism 2 raps the first transmission rod 4. The second rapping mechanism 3 is installed on the support frame 1, and is arranged opposite to the second transmission rod 5, so that the second rapping mechanism 3 raps the second transmission rod 5.

[0030] Research has revealed that when the existing design sets up a single rapping mechanism at the lower part of the anode plate 13 and applies it to an anode plate 13 with an internal cavity, the dust on the upper anode plate 13, which is far from the rapping mechanism, is not easily shaken off. This can easily lead to dust accumulation on the upper part of the anode plate 13, resulting in a decrease in the dust removal capacity of the upper anode plate 13 and a tendency to form a back corona.

[0031] As can be seen from the above design, the first vibration mechanism 2 at the upper end of the anode plate 13 vibrates the first transmission rod 4, transmitting the impact to the anode plate 13 and causing it to vibrate, thus causing the dust adhering to the upper end of the anode plate 13 to fall downwards. Similarly, the second vibration mechanism 3 at the lower end of the anode plate 13 vibrates the second transmission rod 5, transmitting the impact to the anode plate 13 and causing it to vibrate, thus causing the dust adhering to the lower end of the anode plate 13 to fall downwards. Through the arrangement of the first vibration mechanism 2 and the second vibration mechanism 3, the dust at both the upper and lower ends of the anode plate 13 can be promptly removed under vibration, preventing back corona discharge from the anode plate 13 and improving the dust removal effect.

[0032] Furthermore, the first vibration mechanism 2 and the second vibration mechanism 3 are respectively staggered and arranged on opposite sides of the anode plate 13.

[0033] It is known that to maximize the removal of dust from the anode plate 13, one approach is to increase the number of rapping mechanisms and to increase the amplitude and frequency of the rapping. However, increasing the number of rapping mechanisms increases both the manufacturing cost of the equipment and the energy consumption, leading to significant energy waste. Furthermore, increasing the amplitude and frequency of the rapping can exacerbate the re-entrainment of the dislodged dust, resulting in a decrease in dust removal efficiency.

[0034] Through the above design, the first rapping mechanism 2 and the second rapping mechanism 3 are staggered. The first rapping mechanism 2 is arranged on one side of the upper end of the anode plate 13 and at the top of the support frame 1, while the second rapping mechanism 3 is arranged on the other side of the lower end of the anode plate 13 and at the bottom of the support frame 1. This arrangement brings the positions on the anode plate 13 away from the first rapping mechanism 2 closer to the second rapping mechanism 3, allowing these positions to be effectively rapped and cleaned by the second rapping mechanism 3. At the same time, the positions on the anode plate 13 away from the second rapping mechanism 3 are brought closer to the first rapping mechanism 2, allowing these positions to be effectively rapped and cleaned by the first rapping mechanism 2. In other words, this arrangement allows the first rapping mechanism 2 and the second rapping mechanism 3 to cover a wider rapping range, and effectively improves the dust removal effect without increasing the amplitude and frequency.

[0035] Furthermore, the first transfer rod 4 is arranged in a horizontal direction, and the second transfer rod 5 is arranged in a horizontal direction. Both the first transfer rod 4 and the second transfer rod 5 are detachably connected to the anode plate 13 by bolts, which facilitates replacement.

[0036] It is known that by arranging the first transmission rod 4 horizontally, when the first vibration mechanism strikes the first transmission rod 4 in the horizontal direction, it drives the anode plate 13 to vibrate in the horizontal direction. Because there is no need to do work to overcome the gravity of the anode plate 13 when vibrating in the horizontal direction, the energy generated by the strike can be used more to drive the anode plate 13 to vibrate in the horizontal direction, thus making the vibration effect better.

[0037] Furthermore, it also includes a first vibrating anvil 6 and a second vibrating anvil 7. The first vibrating anvil 6 is fixedly connected to the first transmission rod 4 by welding, and the first vibrating anvil 6 is arranged at one end near the first vibrating mechanism 2; the second vibrating anvil 7 is fixedly connected to the second transmission rod 5, and the second vibrating anvil 7 is arranged at one end near the second vibrating mechanism 3. Both the first vibrating anvil 6 and the second vibrating anvil 7 are made of wear-resistant materials to improve their service life.

[0038] It can be understood that by setting the first vibrating anvil 6 and the second vibrating anvil 7, the first vibrating mechanism 2 directly vibrates the first vibrating anvil 6 and transmits the vibration to the first transmission rod 4 and the anode plate 13 through the first vibrating anvil 6; the second vibrating mechanism 3 directly vibrates the second vibrating anvil 7 and transmits the vibration to the second transmission rod 5 and the anode plate 13 through the second vibrating anvil 7; this prevents the first vibrating mechanism 2 from directly vibrating the first transmission rod 4, which would cause damage to the first transmission rod 4, and at the same time prevents the second vibrating mechanism 3 from directly vibrating the second transmission rod 5, which would cause damage to the second transmission rod 5, thereby improving the service life of the first transmission rod 4 and the second transmission rod 5.

[0039] Furthermore, it also includes arc-shaped supports 8, two of which are arranged at the lower parts of both ends of the first transmission rod 4, and the two arc-shaped supports 8 are arranged on the same axis; the first transmission rod 4 is swayably supported on the support frame 1 by the two arc-shaped supports 8.

[0040] It is known that the two arc-shaped supports 8 are arranged coaxially, and the axis of the arc-shaped supports 8 is arranged along the width direction of the anode plate 13. Through this arrangement, the anode plate 13 is kept vertical under the action of gravity, and all anode plates 13 in the same system are kept parallel, thereby improving the dust purification effect.

[0041] Furthermore, it also includes a weight sensor 9, with two weight sensors 9 arranged in a one-to-one correspondence with two arc-shaped supports 8. The first end of the weight sensor 9 is connected to the first transmission rod 4, and the second end of the weight sensor 9 is connected to the arc-shaped support 8. The first transmission rod 4, the weight sensor 9, and the arc-shaped support 8 are arranged sequentially from top to bottom.

[0042] It is understood that the weight of the anode plate 13 is measured in real time by the weight sensor 9. As dust gradually adheres to the anode plate 13, its weight slowly increases. The weight sensor 9 converts the weight signal into a voltage signal and emits the voltage signal. The two weight sensors 9 jointly bear the weight of the anode plate 13 and the dust. Of course, in some other embodiments of this application, the weight signal can also be converted into a current signal.

[0043] Furthermore, it also includes protective rubber sleeves 10, two of which are arranged, with each protective rubber sleeve 10 corresponding to one of the two weight sensors 9. The protective rubber sleeves 10 are arranged around the outside of the weight sensors 9. The first end of the protective rubber sleeve 10 is fixedly connected to the first transmission rod 4, and the second end of the protective rubber sleeve 10 is fixedly connected to the arc-shaped support 8.

[0044] It is understood that by setting the protective sleeve 10, dust is prevented from contacting the weight sensor 9, preventing dust from entering the weight sensor 9 and causing damage to the weight sensor 9, creating a cleaner environment for the weight sensor 9, and improving the service life of the weight sensor 9.

[0045] Furthermore, it also includes a controller 11, the first end of which is connected to the weight sensor 9, the second end of which is connected to the first vibration mechanism 2, and the third end of which is connected to the second vibration mechanism 3.

[0046] It is understood that during operation, the weight sensor 9 converts the weight signal into an electrical signal (specifically, a voltage signal or a current signal) and sends it to the controller 11. When the electrical signal reaches a set value, the controller 11 controls the first rapping mechanism 2 to operate continuously for a period of time, such as ten seconds, after which the first rapping mechanism 2 stops operating and the controller 11 controls the second rapping mechanism 3 to operate continuously for a period of time, such as ten seconds, after which the controller 11 stops operating, completing one rapping cycle. When the signal transmitted from the weight sensor 9 to the controller 11 reaches the set value for the second time, the controller 11 controls the first rapping mechanism 2 and the second rapping mechanism 3 to operate for the second time, and so on. Through this operating mode, the first rapping mechanism 2 operates, causing the dust above the anode plate 13 to fall downwards. Some dust may be adsorbed by the anode plate 13 below. Then, by operating the second rapping mechanism 3, the dust below the anode plate 13 falls, thus cleaning as much dust as possible from the anode plate 13.

[0047] It should be noted that in some other embodiments of this application, the first vibration mechanism 2 and the second vibration mechanism 3 may work simultaneously, or the second vibration mechanism 3 may work first, and then the first vibration mechanism 2 may work.

[0048] Furthermore, it also includes a dust hopper 12, which is arranged directly below the anode plate 13. The two sides of the dust hopper 12 are arranged as inclined surfaces so that the falling dust can be concentrated in the middle of the dust hopper 12.

[0049] It is known that the dust falling from the anode plate 13 is collected by the ash hopper 12, which facilitates the subsequent centralized treatment of the dust.

[0050] Example 2:

[0051] This embodiment provides a rapping dust removal system for the anode plate 13 of an electrostatic precipitator, referring to... Figure 4The difference between this embodiment and Embodiment 1 is that, in this embodiment, the first rapping mechanism 2 and the second rapping mechanism 3 are arranged on the same side of the anode plate 13. The first rapping mechanism 2 is used to rappel and clean the upper end of the anode plate 13, and the second rapping mechanism 3 is used to rappel and clean the lower end of the anode plate 13, thereby achieving a comprehensive cleaning of the anode plate 13.

[0052] The remaining aspects are basically the same as in Example 1, and will not be repeated here.

[0053] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
