Description

Technical Field

[0001] This utility model relates to the field of dust removal device technology, and in particular to an electrostatic precipitator and electrostatic precipitator system for enhanced dust collection. Background Technology

[0002] In industries such as power, metallurgy, chemical, and building materials, electrostatic precipitators (ESPs) are widely used for treating dust-laden gases to effectively separate dust from gas, meeting the demands of energy conservation, emission reduction, and environmental protection. The working principle of an ESP lies in using a high-voltage electric field to charge dust particles in the flue gas, thereby efficiently separating these charged particles from the airflow and collecting them on a dust collection plate. Subsequently, the dust is collected by rapping and cleaning, causing it to fall into an ash hopper.

[0003] However, in the actual operation of electrostatic precipitators, a phenomenon often occurs—insufficient dust charge in the electric field. Specifically, the secondary voltage and current in the first electric field are low, but gradually increase with the increase in the electric field level. The main reason for this is that the dust concentration is high when first entering the electric field, preventing the dust particles from being fully charged. In this situation, the dust particles, lacking sufficient electric field force, cannot be adsorbed onto the corresponding anode plates, thus failing to form a large current loop, resulting in a low current value. However, when the dust particles enter the next electric field with the flue gas, they undergo a re-charging process, increasing their charge and eventually being adsorbed onto the anode plates, forming a larger current loop. Therefore, the secondary voltage and current gradually increase with the increase in the electric field level. This phenomenon indicates that traditional electrostatic precipitators have limitations in dust charging efficiency, especially when handling high-concentration dust, making it difficult to ensure that all dust particles are fully charged before entering subsequent electric fields. This problem not only affects dust removal efficiency but may also lead to increased energy consumption and unstable equipment operation. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an electrostatic precipitator with enhanced dust collection. The electrostatic precipitator includes several dust collection areas spaced apart along the airflow direction. The several dust collection areas are connected to several ash hoppers in a one-to-one correspondence. The ash hoppers are arranged below the dust collection areas perpendicular to the airflow direction. At least one dust collection area is connected to an enhanced dust collection component.

[0005] In conjunction with the first aspect, the direction of flue gas flow in the dust removal component is set at the front end of the dust removal area.

[0006] In conjunction with the first aspect, the dust removal components are positioned at the rear end of the dust removal area along the airflow direction.

[0007] In conjunction with the first aspect, the direction of flue gas flow of the dust removal components is strengthened by setting them at the front and rear ends of the dust removal area.

[0008] In conjunction with the first aspect, the enhanced dust removal components include:

[0009] The reinforced cathode wire is connected to the cathode frame within the dust removal area; the reinforced cathode wire has a discharge tip that generates corona discharge.

[0010] The auxiliary anode plate is connected to the anode plate in the dust removal area.

[0011] In conjunction with the first aspect, the length of the discharge tip along the airflow direction is 10-150 mm.

[0012] In conjunction with the first aspect, the distance between two adjacent discharge tips perpendicular to the airflow direction is 50-150 mm.

[0013] In conjunction with the first aspect, a cathode frame, anode plates, and cathode wires are provided in the dust removal area. The cathode wires are installed on the cathode frame, and multiple anode plates are connected in series in a direction perpendicular to the airflow to form an anode plate row. The multiple anode plate rows and multiple cathode wires are alternately arranged in the airflow direction. A voltage is applied between the cathode wires and the anode plate rows to form a dust removal electric field.

[0014] In conjunction with the first aspect, the dust removal area also includes:

[0015] The output end of the anode rapping assembly acts on the anode plate array to rappel the anode plate and the auxiliary anode plate.

[0016] The cathode rapping assembly's output acts on the cathode frame to rappel and reinforce the cathode wires.

[0017] Secondly, embodiments of this application also provide an electrostatic precipitator system, including the electrostatic precipitator as described above.

[0018] This application provides an electrostatic precipitator and electrostatic precipitator system for enhanced dust removal. The electrostatic precipitator includes: a plurality of dust removal zones spaced apart along the airflow direction, the plurality of dust removal zones being connected to a plurality of ash hoppers in a one-to-one correspondence, and the ash hoppers being arranged below the dust removal zones perpendicular to the airflow direction; wherein at least one dust removal zone is connected to an enhanced dust removal component.

[0019] This application employs a multi-stage dust collection system within an electrostatic precipitator, with multiple dust collection zones spaced apart along the airflow direction. This staged treatment of dust-laden gas ensures that dust particles are fully charged and captured as they pass through each electric field. Even if some dust particles are not completely captured in the preceding electric field, they can be efficiently separated by recharging in subsequent electric fields. This staged optimization significantly improves the overall performance of the electrostatic precipitator. Furthermore, at least one dust collection zone is connected to a reinforced dust collection component, which can further enhance the electric field strength or improve particle charging based on actual operating conditions (such as dust properties and airflow velocity). This not only overcomes the shortcomings of traditional electrostatic precipitators in handling high-concentration dust or difficult-to-capture particles but also flexibly adapts to dust collection needs in different scenarios, significantly improving the applicability and performance of the equipment.

[0030] 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.

[0031] To facilitate understanding of this embodiment, the technical terms used in this application will be briefly introduced below.

[0032] Electrostatic precipitators primarily utilize the principle of electrostatics to separate particulate matter from dust-laden airflow. Their working process typically includes the following steps: Ionization stage: Under the influence of a high-voltage electric field, the gas is ionized, forming a large number of positive and negative ions; Charging stage: After the dust-laden airflow enters the electric field, the dust particles adsorb ions and become charged; Collection stage: Under the influence of the electric field, the charged dust particles move towards the electrodes and deposit on the electrode surface; Cleaning stage: The dust deposited on the electrodes is removed by methods such as rapping or blowing.

[0033] The dust hopper is an important component of an electrostatic precipitator. Located at the bottom of the precipitator, it is used to collect and store the dust removed from the electrodes. The inner wall of the dust hopper is designed with a certain inclination angle so that the dust can slide smoothly to the bottom and prevent dust accumulation. In addition, the dust hopper needs to have good sealing performance to avoid dust leakage and secondary pollution.

[0034] 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.

[0035] Based on this, this application provides a cookware adapter and cooking system for use with an induction cooker.

[0036] Example 1

[0037] This application provides an electrostatic precipitator with enhanced dust collection, combined with... Figure 1As shown, the electrostatic precipitator includes: a plurality of dust removal zones 1 arranged at intervals along the airflow direction, the plurality of dust removal zones 1 being connected to a plurality of ash hoppers 2 in a one-to-one correspondence, the ash hoppers 2 being arranged below the dust removal zones 1 perpendicular to the airflow direction; wherein, at least one dust removal zone 1 is connected to an enhanced dust removal component 3.

[0038] In this embodiment, multiple dust collection zones 1 in the electrostatic precipitator are connected to the ash hopper 2 in a one-to-one correspondence, which helps the collected dust to fall directly into the ash hopper, effectively reducing the possibility of secondary dust generation, thereby ensuring the stable operation of the entire system. Furthermore, at least one dust collection zone 1 is connected to an enhanced dust collection component 3. In this way, different enhanced dust collection components 3 can be configured in different dust collection zones 1 according to actual working conditions, which enhances the equipment's adaptability to various complex working conditions and significantly improves its ability to capture fine particulate matter.

[0039] Combination Figure 1 As shown, the arrows indicate the airflow direction, and multiple dust removal zones 1 are spaced apart along this direction. When the airflow passes through each dust removal zone 1, the electrostatic dust removal capacity of that zone removes dust particles from the airflow. Specifically:

[0040] Under the influence of a high-voltage DC power supply, a strong electric field is formed inside the dust removal zone 1. When the dust-laden airflow enters this electric field, the gas molecules are ionized, generating a large number of positive and negative ions and free charges. These charged particles collide with dust particles, causing the dust particles to adsorb charges and become charged particles. Typically, dust particles will acquire either a negative charge (cathode discharge) or a positive charge (anode discharge), depending on their position in the electric field and the polarity of the electrodes. Charged dust particles move towards electrodes of opposite polarity under the influence of the electric field force. For example, negatively charged dust particles are attracted to the anode plate, while positively charged dust particles are attracted to the cathode wire. After reaching the electrode surface, the dust particles lose their charge and deposit, thus achieving separation from the airflow. Over time, the dust deposited on the electrodes gradually increases, requiring periodic removal to ensure dust removal efficiency. Generally, mechanical shaking or airflow backflushing is used to shake the dust off into the ash hopper 2 below for collection.

[0041] In this embodiment, the entire electrostatic precipitator process is divided into multiple sub-processes by using multiple dust removal zones 1 arranged at intervals. At least one dust removal zone 1 is connected to an enhanced dust removal component 3 to perform enhanced dust removal in that sub-process of the overall electrostatic precipitator process. This can achieve local or overall enhancement of the dust removal effect and adapt to different working requirements.

[0042] In conjunction with the first aspect, the flue gas flow direction of the enhanced dust removal component 3 is set at the front end of the dust removal area 1.

[0043] In this embodiment, as an implementable approach, an enhanced dust removal component 3 is connected to the front end of at least one dust removal zone 1 along the flue gas flow direction. This allows the airflow to undergo preliminary treatment by the enhanced dust removal component 3 before entering the dust removal zone 1, removing larger particles or high concentrations of pollutants. This helps reduce the workload of the subsequent conventional dust removal zone 1 and improves overall dust removal efficiency. Since the enhanced dust removal component 3 has already removed most of the easily captured particles, the subsequent conventional dust removal zone 1 can operate with lower energy consumption, thereby achieving the goal of energy conservation and emission reduction.

[0044] Understandably, as the airflow passes through different dust removal zones 1, the dust in the airflow is gradually removed. By connecting the enhanced dust removal component 3 to the front end of one or more dust removal zones 1, the dust removal effect can be enhanced locally. If the front end of all dust removal zones 1 is connected to the enhanced dust removal component 3, then pretreatment is performed before the airflow passes through any dust removal zone 1, thereby improving the overall dust removal efficiency and optimizing the energy consumption performance of the entire electrostatic precipitator.

[0045] In conjunction with the first aspect, the dust removal component 3 is positioned at the rear end of the dust removal area 1 along the airflow direction.

[0046] In this embodiment, as another feasible approach, at least one dust removal zone 1 along the flue gas flow direction is connected to the rear end of an enhanced dust removal component 3. After the airflow passes through the dust removal zone 1 and dust particles are removed, the enhanced dust removal component 3 can further remove residual fine particles or difficult-to-capture pollutants in the airflow, thereby achieving higher emission standards. During the operation of the electrostatic precipitator, deposited dust may be re-entrained due to airflow disturbances, a phenomenon known as "secondary dust re-entrainment." The enhanced dust removal component 3, located at the rear end, can effectively capture these re-entrained dust particles, ensuring the quality of the final emitted gas.

[0047] Furthermore, in certain special cases, the flue gas may contain complex components (such as high resistivity dust, sticky substances, etc.), which may not be effectively captured by conventional dust collection zones 1. Placing the enhanced dust collection component 3 at the rear end allows for optimized design specifically for these difficult-to-handle components, improving the overall system's adaptability.

[0048] In conjunction with the first aspect, the direction of flue gas flow of the dust removal components is strengthened by setting them at the front and rear ends of the dust removal area.

[0049] As another feasible approach, combining the two aforementioned approaches, enhanced dust collection components 3 are connected to both the front and rear ends of the dust collection zone 1. This allows for both pretreatment of the airflow entering the dust collection zone 1 and deep purification of the airflow exiting the zone, reducing secondary dust generation. This dual-enhanced dust collection design at both the front and rear ends can comprehensively cover all types of pollutants in the flue gas, effectively treating everything from large to fine particles, significantly improving dust collection efficiency to meet higher emission standards. Furthermore, by using conventional dust collection technology at the front end to remove most easily captured particles, and then using enhanced dust collection technology at the rear end to treat the remaining stubborn particles, this staged treatment method optimizes the overall system's energy consumption while ensuring effective dust collection.

[0050] Please refer to Figure 1 An exemplary schematic diagram of an enhanced dust collection electrostatic precipitator is provided, which includes four dust collection zones 1, each with a dust hopper 2 connected below it. Figure 1 In this system, each dust removal zone 1 is connected to both its front and rear ends with enhanced dust removal components 3. This maximizes dust removal efficiency and reduces secondary dust generation.

[0051] In conjunction with the first aspect, the enhanced dust removal component 3 includes: an enhanced cathode wire 31 and an auxiliary anode plate 32.

[0052] The reinforced cathode wire 31 is connected to the cathode frame 11 within the dust removal area 1; the reinforced cathode wire 31 has a discharge tip that generates corona discharge, such as... Figure 3 , Figure 4 , Figure 5 As shown.

[0053] The auxiliary anode plate 32 is connected to the anode plate 13 in the dust removal area 1.

[0054] Understandably, dust removal area 1 typically includes a cathode system and an anode system. The cathode system includes a cathode frame 11 and a cathode wire 12. The anode system includes an anode plate array, which is formed by connecting multiple anode plates 13 in series.

[0055] The cathode wire 12 is a key component for generating corona discharge, and its shape and material directly affect the electric field strength and the charging efficiency of particles. Common types of cathode wires include serrated wires, herringbone wires, and star-shaped wires. The cathode frame 11 is used to fix the cathode wire 12 and ensure that it maintains a stable arrangement in the electric field.

[0056] The anode plate 13 (dust collection plate) is the main component for collecting charged particles. It is usually made of metal and has a large surface area to improve the capture efficiency of particles.

[0057] In this application, the reinforced cathode wire 31 is fixed to the cathode frame 11 of the conventional dust removal area 1 by physical or electrical connection to ensure that the reinforced cathode wire 31 can operate stably under high voltage while maintaining a reasonable distance from the anode plate 13. The reinforced cathode wire 31 has a discharge tip, which enables it to generate corona discharge more effectively and enhance the electric field strength, such as... Figure 5 The reinforced cathode wire 31 is made of thin steel plate and includes a main rod and barbs. The discharge tip of the reinforced cathode wire 31, used to enhance the charged electric field, is an RS tubular barb wire. This discharge tip can also be an RSB barb wire, a needle-punched wire, etc. The barbs are spot-welded to the main rod. The function of the barbs is to continuously release corona current under high voltage, so that the dust can be charged. The barbs can be curved or flat.

[0058] When a high voltage is supplied to the cathode wire 12 and the anode plate 13, a strong corona discharge phenomenon occurs at the discharge tip of the enhanced cathode wire 31. This corona discharge causes the particulate matter in the flue gas to become charged (negative or positive, depending on the polarity of the electric field). The high-intensity electric field allows more particulate matter to be effectively charged, thereby improving the dust removal efficiency of the entire system.

[0059] Along the direction perpendicular to the airflow, the cathode frame 11 can be divided into upper, middle, and lower layers in the electric field height direction. The reinforcing cathode wire 31 is located between adjacent layers of the cathode frame 11 and is connected to the anode plate 13 of the conventional dust removal area by mechanical fixing (in this embodiment, by bolted connections) or welding. The auxiliary anode plate 32 is connected to the anode plate 13 by mechanical fixing or welding to ensure a uniform electric field distribution between the auxiliary anode plate 32 and the anode plate 13, thereby optimizing the airflow path, increasing the residence time of particles in the electric field, and improving collection efficiency. In this embodiment, the auxiliary anode plate 32 is connected to the anode plate 13 by blind rivets. The opening of the auxiliary anode plate 32 can be arranged in the same or opposite direction to the airflow direction; the auxiliary anode plate 32 can be a flat-bottomed V-shaped, flat-bottomed U-shaped, or flat plate structure.

[0060] Along the airflow direction, the auxiliary anode plate 32 can be positioned in front of or behind the row of anode plates 13, and the auxiliary anode plate 32 is interconnected with the anode plate 13. An appropriate discharge distance, i.e., the inter-electrode spacing, needs to be maintained between the reinforcing cathode line 31 and the auxiliary anode plate 32. The height of the auxiliary anode plate 32 is designed to be consistent with that of the anode plate 13. Simultaneously, the reinforcing cathode line 31 can be arranged in layers within a height space perpendicular to the airflow direction.

[0061] In application, charged particles move towards the anode plate under the influence of the electric field and eventually deposit on its surface. The auxiliary anode plate 32 further improves the particle capture efficiency by optimizing airflow distribution and increasing particle residence time. Furthermore, setting the auxiliary anode plate 32 at the rear end can effectively capture re-entrained dust, reducing secondary dust generation.

[0062] Understandably, the combined use of the enhanced cathode wire 31 and the auxiliary anode plate 32 can play different roles at the front and rear ends of the dust removal area. When the enhanced dust removal component 3 is located at the front end, the enhanced cathode wire 31 is mainly used for rapidly charging aerosol particles, while when the enhanced dust removal component 3 is located at the rear end, the auxiliary anode plate 32 is responsible for deep purification of residual fine particles.

[0063] In practical applications, the structure can be set according to the actual dust removal needs. First, the dust removal area 1 that needs to be enhanced can be determined. By connecting the front end, the back end, and the front end and the back end to enhance the dust removal components 3, different dust removal effect enhancement requirements can be achieved to improve the overall dust removal efficiency.

[0064] Combination Figure 2 As shown, the middle area is the existing multiple dust removal areas 1. The electric field formed between the cathode wire 12 and the anode plate 13 in the dust removal area 1 is shown by the dashed line in the dust removal area 1 in the figure. Along the airflow direction, there are enhanced dust removal components 3 in front of and behind the dust removal area 1. The electric field formed between the enhanced cathode wire 31 and the auxiliary anode plate 32 is shown by the dashed line in the enhanced dust removal component 3.

[0065] In conjunction with the first aspect, the length of the discharge tip along the airflow direction is 10-150 mm.

[0066] Along the airflow direction, the length of the discharge tip is set to 10-150mm to ensure that the discharge tip can form a stable corona discharge area in the airflow. A longer discharge tip can cover a larger space, enhance the electric field strength, and improve the charging efficiency of particulate matter. At the same time, reasonable control of the discharge tip length can avoid corona blockage caused by excessive length.

[0067] In conjunction with the first aspect, the distance between two adjacent discharge tips perpendicular to the airflow direction is 50-150 mm.

[0068] The distance between two adjacent discharge tips is set to 50-150 mm perpendicular to the airflow direction to ensure sufficient overlap between the corona discharge areas, thereby improving the uniformity of the electric field intensity distribution throughout the dust removal area. If the distance between the discharge tips is too small, it may lead to corona blockage; while if the distance is too large, it may reduce the electric field intensity and charging efficiency. In this embodiment, by optimizing the length and distance of the discharge tips, a uniform electric field intensity distribution is ensured, reducing the phenomenon of excessively strong or weak local electric fields. The enhanced cathode wire can form a stable corona discharge area in the airflow, improving the charging efficiency of particulate matter. The auxiliary anode plate 32 can effectively capture residual fine particles or particles that are difficult to charge, achieving a comprehensive dust removal effect.

[0069] In conjunction with the first aspect, a cathode frame 11, an anode plate 13, and a cathode wire 12 are provided in the dust removal area 1. The cathode wire 12 is installed on the cathode frame 11. Multiple anode plates 13 are connected in series in a direction perpendicular to the airflow to form an anode plate row. Multiple anode plate rows and multiple cathode wires 12 are alternately arranged in the airflow direction. A voltage is applied between the cathode wire 12 and the anode plate 13 to form a dust removal electric field.

[0070] In this embodiment, multiple anode plates and multiple cathode wires 12 are alternately arranged along the airflow direction to form a uniform electric field distribution. A uniform dust removal electric field is formed between each cathode wire 12 and the adjacent anode plate by applying a high voltage. The reinforced cathode wires 31 are fixed to the conventional cathode frame 11, and the spacing between their discharge tips (50-150 mm along the perpendicular direction of the airflow) is optimized to ensure overlapping coverage of the corona discharge area.

[0071] When a high voltage is applied between the cathode wire 12 and the anode plate array by a high-voltage power supply, a strong corona discharge phenomenon occurs at the discharge tip of the cathode wire 12. This corona discharge causes the particulate matter in the flue gas to become charged (negative or positive, depending on the polarity of the electric field), completing the charging process. Under the action of the electric field force, the charged particulate matter moves towards each anode plate 13 and eventually deposits on its surface. The conventional anode plate 13 is responsible for collecting most of the particulate matter, while the auxiliary anode plate 32 further captures the remaining fine particulate matter or particulate matter that is difficult to charge (such as high resistivity dust).

[0072] Based on the above examples, the discharge tip design of the enhanced cathode wire 31 (length 10-150mm, spacing 50-150mm) enhances the electric field strength and improves the charging efficiency of particulate matter; the introduction of the auxiliary anode plate 32 optimizes the airflow distribution, reduces eddies and short circuits, and prolongs the residence time of particulate matter in the electric field, thus achieving deep purification.

[0073] In conjunction with the first aspect, the dust removal area 1 is also equipped with an anode rapping assembly 4 and a cathode rapping assembly 5.

[0074] The output end of the anode rapping assembly 4 acts on the anode plate row to rappel the anode plate 13 and the auxiliary anode plate 32.

[0075] The output end of the cathode rapping assembly 5 acts on the cathode frame 11 to rappel the cathode wire 12 and the reinforced cathode wire 31.

[0076] Understandably, the output of the anode rapping assembly 4 acts on the anode plate array, removing particles deposited on the surface of each anode plate 13 through mechanical vibration, and shaking the particles into the collection device below (such as the ash hopper 2). This process ensures that the surface of the anode plate 13 remains clean, thereby maintaining a highly efficient and stable dust removal effect. In addition, since the auxiliary anode plate 32 is fixedly connected to the anode plate 13 by a core-pulling rivet, when the anode plate 13 is rapped, the rapping force is transmitted to the auxiliary anode plate 32 to rappe the auxiliary anode plate 32, thereby cleaning the particles adsorbed on the auxiliary anode plate 32.

[0077] Similarly, the output end of the cathode rapping assembly 5 acts on the cathode frame 11 to rappel the cathode wire 12 and the reinforced cathode wire 31, so as to shake off the dust particles on the cathode wire 12 and the reinforced cathode wire 31.

[0078] In practical applications, both the anode rapping assembly 4 and the cathode rapping assembly 5 include key components such as a drive unit, a transmission mechanism, a rapping hammer, and a rapping rod. The drive unit (such as an electric motor) is connected to the transmission mechanism (e.g., a gear set or chain drive system) via a coupling, converting rotational motion into linear motion or directly transmitting it to the rapping rod. One end of the rapping rod is connected to the transmission mechanism, and the other end is fixed with the rapping hammer. When power is transmitted to the rapping rod, the rapping rod drives the rapping hammer to perform periodic striking motions, thereby generating mechanical vibration on the anode plate 13 or cathode wire 12 to remove surface dust. This is essentially the same as related technologies and will not be elaborated upon here.

[0079] Furthermore, regular cleaning can prevent excessive particle accumulation, which could lead to a decrease in electric field strength or reduced equipment operating efficiency. In addition, appropriate rapping frequency and force can effectively prevent secondary dust generation and extend the service life of the equipment.
