Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a self-cleaning electrode, dust collector and dust removal system. Background Technology

[0002] Currently, the electrode systems of domestic electrostatic precipitators are problematic when dealing with highly viscous dust such as flocculent foamed dust rich in alkali metal oxides or boiler fly ash mixed with ammonia sulfate that has escaped during denitrification. This dust tends to clump onto the electrode surface, resulting in poor cleaning efficiency, or even complete inability to remove it. A thick layer of dust remains on the electrode, severely impacting the secondary current and voltage of the electrostatic precipitator, leading to unstable operation and low dust removal efficiency. Faced with increasingly severe environmental pressures, there is an urgent need for a self-cleaning electrode system suitable for highly viscous dust. Utility Model Content

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0043] To facilitate understanding of this embodiment, the technical terms used in this application will be briefly introduced below.

[0044] In an electrostatic precipitator, the anode plate carries a positive charge and attracts negatively charged dust particles, thereby adsorbing the dust particles onto the surface of the anode plate and achieving dust removal from the external environment.

[0045] After introducing the technical terms used in this application, the application scenarios and design concepts of the embodiments of this application will be briefly described below.

[0046] The plate system of electrostatic precipitators is ineffective at cleaning highly sticky dust, which seriously affects the secondary current and voltage of the electrostatic precipitator, leading to unstable operation and low dust removal efficiency.

[0047] Based on this, this application provides a self-cleaning electrode, dust collector, and dust removal system.

[0048] Example 1

[0049] This application provides a self-cleaning electrode assembly, combined with... Figure 1 As shown, the self-cleaning electrode includes: electrode assembly 1, flexible arm hammer vibration device 2, and scraper dust removal device 3.

[0050] The electrode assembly 1 includes several independently rolled anode plates spaced apart. Multiple anode plates are connected in series through a first connector to form a dust collection surface of 2.5 to 5m. The top of the electrode assembly 1 is suspended in the dust collector by a suspension beam, and the bottom is pressed by an impact rod 11 to form an integral structure. One end of the impact rod 11 is provided with an impact anvil 12.

[0051] The flexible arm hammer oscillator 2 is installed on one side of the electrode assembly 1 and cleans the electrode assembly 1 by vibrating the impact anvil 12.

[0052] The scraper cleaning device 3 includes a drive assembly, a transmission assembly, and a scraper assembly 36. The drive assembly drives the transmission assembly to reciprocate along the surface of the pole assembly 1 to perform scraping and cleaning.

[0053] The flexible arm hammer oscillating device 2 and the scraper cleaning device 3 are respectively connected to the control unit 5 and are configured to independently control the periodic operation of the flexible arm hammer oscillating device 2 and the scraper cleaning device 3 to be triggered to operate according to the working conditions.

[0054] The self-cleaning electrode assembly in this embodiment includes a flexible arm hammer oscillating device 2 and a scraper cleaning device 3. Different cleaning methods can be used to clean the anode plates inside the electrode assembly 1. The control unit 5 is configured to independently control the periodic operation of the flexible arm hammer oscillating device 2 and the scraper cleaning device 3 to be triggered to operate according to working conditions, so as to select different cleaning methods for different cleaning needs to clean the electrode plates, thereby efficiently cleaning the electrode assembly.

[0055] The first connector is a metal connector used to connect multiple independent rolled anode plates in series and maintain the spacing between adjacent anode plates. The impact rod includes an elastic buffer component to reduce the impact force of the rapping on the bottom of the electrode assembly 1, so as to prevent deformation or damage to the anode plates.

[0056] Preferably, the suspension beam includes an adjustment mechanism for adjusting the installation height and level of the electrode assembly within the dust collector. This adjustment mechanism can be one of the following: a screw-type adjustment mechanism, a hydraulic adjustment mechanism, a spring-balanced adjustment mechanism, a slide rail adjustment mechanism, an electric screw-type adjustment mechanism, a chain-type adjustment mechanism, or a combined adjustment mechanism. All of these methods are applicable and not limited here. In this embodiment, a screw-type adjustment mechanism can be used. Specifically, a screw (such as a trapezoidal screw or a fine-pitch screw) is installed on the suspension beam. One end of the screw is fixed to the top plate or frame of the dust collector, and the other end is connected to the suspension point of the electrode assembly 1. This allows for precise height adjustment by rotating the screw and fine-tuning of the level of the electrode assembly.

[0057] In conjunction with the first aspect, the flexible arm hammer rapping device 2 includes: a rotating shaft 21, a harmonic reducer (not shown in the figure), a drive motor (not shown in the figure), and a rapping hammer 22 (such as...). Figure 2 (As shown).

[0058] The rotating shaft is mounted on the support frame inside the dust collector on both sides of the electrode assembly 1 via two sets of IP65 dust bearings.

[0059] The harmonic reducer is fixed on the side wall support of the dust collector housing, and its output shaft is coaxially connected to the rotating shaft 21.

[0060] The drive motor is connected to the input shaft of the harmonic reducer via a coupling.

[0061] The vibratory hammer 22 is rigidly connected to the rotating shaft by a clamp and is located on the anvil side of the pole assembly 1.

[0062] Understandably, the drive motor is connected to the input shaft of the harmonic reducer via a coupling. The harmonic reducer is fixed to the side wall support of the dust collector housing, and its output shaft is coaxially connected to the rotating shaft 21. When the drive motor starts, the power it generates is transmitted to the harmonic reducer via the coupling. The harmonic reducer converts the high-speed, low-torque input into a low-speed, high-torque output, thereby driving the rotating shaft to rotate slowly and powerfully. Since the vibrating hammer 22 is rigidly connected to the rotating shaft 21 via a clamp, as the rotating shaft rotates, the vibrating hammer 22 swings and eventually impacts the anvil side of the electrode assembly 1. This impact causes the electrode assembly 1 to vibrate, thereby removing the accumulated dust adhering to the surface. In addition, the rotating shaft is mounted on the support frame inside the dust collector on both sides of the electrode assembly 1 via IP65 dust-proof bearings, ensuring that the entire device can operate stably for a long time in a harsh, dust-filled environment.

[0063] In summary, this device, through the cooperation of a drive motor, a harmonic reducer, and a rotating shaft, enables the vibrating hammer to periodically and effectively vibrate and clean the pole assembly 1.

[0064] In conjunction with the first aspect, the transmission assembly includes: a ring chain 31, an upper drive shaft 32, a lower driven shaft 33, a first sprocket 34, and a second sprocket 35.

[0065] The ring chain 31 forms a closed loop along the centerline of two adjacent rows of anode plates. Figure 3 As shown, a closed loop is formed in the center of the two adjacent rows of anode plates near the anvil 12.

[0066] The upper drive shaft 32 is installed on the top of the dust collector housing, located at the center of two adjacent rows of anode plates. The two ends of the upper drive shaft 32 are equipped with first sprockets 34, and the two first sprockets 34 are connected to the drive assembly through a drive chain.

[0067] The lower driven shaft 33 is installed at the bottom of the dust collector housing, opposite to the upper drive shaft 32, and located at the center of two adjacent rows of anode plates. The two ends of the lower driven shaft 33 are equipped with second sprockets 35.

[0068] The ring chain 31 engages with both the first sprocket 34 and the second sprocket 35.

[0069] In this embodiment, the drive assembly is installed on the top of the dust collector housing, transmitting forward or reverse power to the upper drive shaft 32 via a transmission chain and sprocket assembly. When the upper drive shaft 32 rotates, the first sprockets 34 at both ends rotate accordingly, driving the ring chain 31 meshing with it. The lower part of the ring chain 31 meshes with the second sprockets 35 at both ends of the lower driven shaft 33, ensuring the stable operation of the entire closed-loop transmission system. Since the lower driven shaft 33 is unpowered and suspended at the bottom of the ring chain 31 by its own weight, the second sprockets 35 at both ends act only as passive sprockets, providing support and guidance to ensure that the ring chain 31 does not deviate or jam during movement.

[0070] In conjunction with the first aspect, the scraper assembly 36 includes: a mounting bracket 37 and a scraper 38.

[0071] Mounting bracket 37 is located on one side of the pole row and is fixedly connected to a designated link of the link chain 31.

[0072] The scraper 38 is mounted on the mounting bracket 37 and the scraping surface of the scraper 38 faces the electrode assembly 1, such as... Figure 4 As shown.

[0073] In this embodiment, the scraper 38 is mounted on the mounting bracket 37, thereby fixing the scraper 38 to a designated link of the chain 31. As the chain 31 is driven by the drive assembly and the transmission assembly to move forward or backward, the scraper assembly 36 moves up and down within the height range of the electrode assembly 1, scraping the dust accumulated on the surface of two adjacent rows of electrode plates.

[0074] In conjunction with the first aspect, there are two sets of scraper assemblies 36 corresponding to each ring chain 31 on one side of the pole assembly 1. The two sets of scraper assemblies 36 correspond to the upper and lower parts of the pole assembly 1, respectively. The two sets of scraper assemblies 36 are staggered, with a spacing of 1 / 3 of the height of the pole assembly 1.

[0075] Two sets of scraper assemblies 36 are installed on each chain 31 on one side of the electrode assembly 1, acting on the upper and lower parts of one side of the electrode assembly 1 respectively. The two sets of scraper assemblies 36 are staggered on the chain 31 to avoid duplication at the same height. This staggered arrangement reduces interference between the scraper assemblies 36 and improves dust removal efficiency. Furthermore, the vertical distance between the two sets of scraper assemblies 36 is set to 1 / 3 of the height of the electrode assembly 1. This staggered arrangement further reduces interference between the scraper assemblies 36 and improves dust removal efficiency.

[0076] Driven by the drive device, the chain 31 moves up and down along the closed-loop path. During each movement, the two sets of scraper assemblies 36 act on the upper and lower parts of the pole assembly 1 respectively, and perform dust removal operations alternately. Since the two sets of scraper assemblies 36 are staggered and the distance is 1 / 3 of the height of the pole assembly 1, the scraper assemblies 36 can evenly cover the entire height range of the pole assembly 1 throughout the entire movement cycle.

[0077] The scraper assembly 36 has a scraping surface shape that matches the electrode surface and has a set gap with the electrode surface. This design can effectively remove accumulated dust during the cleaning process while protecting the electrode from damage.

[0078] As one possible approach, the two sets of scraper assemblies 36 are located on one side of the electrode assembly 1 to scrape and clean that side; as another possible approach, two sets of scraper assemblies 36 are provided on both sides of the electrode assembly 1 so that during the operation of the chain 31, a total of four sets of scraper assemblies 36 on both sides can be driven to clean the two adjacent anode plates.

[0079] In conjunction with the first aspect, there are multiple scraper cleaning devices 3, each of which corresponds to two adjacent anode plates.

[0080] Understandably, each pair of adjacent anode plates corresponds to one scraper cleaning device 3. For example, if the electrode assembly 1 includes n anode plates spaced apart, then the number of corresponding scraper cleaning devices 3 is n-1. The corresponding n-1 chain links 31 are driven to move, thereby driving the scraper assemblies 36 located on one or both sides of the electrode assembly 1 to clean the two adjacent anode plates. In this way, multiple small-sized scraper cleaning devices 3 replace a large-sized scraper cleaning device 3, with each small-sized scraper cleaning device 3 corresponding to two adjacent anode plates. Even if a scraper cleaning device 3 is damaged, it can be removed and replaced individually.

[0081] In conjunction with the first aspect, it also includes: limit switch 4.

[0082] There are two limit switches 4, which are installed at the end of the upward path and the end of the downward path of the chain 31, respectively. Each limit switch 4 is connected to the control unit 5.

[0083] In this embodiment, a first limit switch 4 is provided at the end of the upward path of the chain 31. When the chain 31 reaches the end of the upward path and triggers the first limit switch 4, the first limit switch 4 is activated and communicates with the control unit 5, and stops running or reverses running under the control of the control unit 5. Similarly, a second limit switch 4 (not shown in the figure) is provided at the end of the downward path of the chain 31. When the chain 31 reaches the end of the downward path and triggers the second limit switch 4, the second limit switch 4 is activated and communicates with the control unit 5, and stops running or resumes forward running under the control of the control unit 5.

[0084] Understandably, the upward path refers to the path along which the chain 31 is driven to move upwards from its starting position. On this path, when the chain 31 reaches its end, the first limit switch 4 is triggered, which then stops or reverses operation via communication with the control unit 5. Similarly, the downward path refers to the path along which the chain 31 is driven to move downwards from its starting position. On this path, when the chain 31 reaches its end, the second limit switch 4 is triggered, which then stops or resumes forward operation via communication with the control unit 5. In this way, when the chain 31 reaches the end of the upward or downward path, its operating state can be changed safely and accurately, avoiding equipment damage or other problems caused by over-operation.

[0085] Combination Figure 5 As shown, during the periodic dust removal operation, the control unit 5 controls the flexible arm hammer vibration device 2 to operate for periodic dust removal. Similarly, during the dust removal operation of the scraper dust removal device 3, the control unit 5 controls the scraper dust removal device 3 to operate. Driven by the chain 31, the scraper 38 cleans the pole assembly 1. At the same time, it receives the signal from the limit switch 4 to determine whether the travel has reached the end of the stroke, and controls the scraper dust removal device 3 to operate based on the determination result.

[0086] In conjunction with the first aspect, the distance between the scraping surface of the scraper 38 and the outer surface of the electrode assembly 1 is 3 to 10 mm.

[0087] In this way, the scraper 38 moves along the height direction of the electrode assembly 1 under the drive of the chain 31 to scrape off the dust on the surface of the electrode assembly 1. Since the scraping surface of the scraper 38 leaves a gap of 3 to 10 mm with the outer surface of the electrode assembly 1, the outer surface of the electrode assembly 1 is avoided during the dust removal process.

[0088] Secondly, this application provides a dust collector, wherein the dust collector is internally suspended with a self-cleaning electrode as described above.

[0089] Thirdly, this application provides a dust removal system, including the dust collector as described above.
