Description

Technical Field

[0001] This invention belongs to the technical field of electrostatic precipitator devices, specifically a collaborative flow equalization electrostatic precipitator device with adaptive flue gas operating conditions. Background Technology

[0002] Electrostatic precipitators are widely used in industrial fields such as thermal power generation, steel smelting, cement manufacturing, and chemical production. Conventional electrostatic precipitators typically adopt a fixed flow channel structure design, where flue gas enters the electric field area through the inlet smoke box and completes the dust removal process through each electric field channel according to a preset flow path. However, in actual engineering, due to factors such as bends and diameter changes in upstream pipelines, there is a significant non-uniformity in the velocity field and concentration of flue gas when it enters the dust collector cross-section (i.e., flow deviation). This causes the electric field channels near the high-speed zone to be under a high dust load for a long time, resulting in insufficient dust charge in this area, aggravated secondary dust re-entrainment, and a decrease in dust removal efficiency. Meanwhile, the channels in the low-speed zone operate at a low load for a long time, which greatly limits the overall processing capacity and operational stability.

[0003] In addition, the various electric field treatment areas of traditional electrostatic precipitators are structurally uniform and fixed. The flue gas passes through all electric field areas according to the same flow channel distribution scheme. It cannot adaptively adjust the treatment channel according to the real-time operating conditions of the flue gas. Under high concentration or abnormal flue gas flow impact conditions, the dust removal efficiency drops sharply and the risk of exceeding the flue gas emission concentration increases significantly. Therefore, it is necessary to provide a collaborative flow equalization electrostatic precipitator with adaptive flue gas operating conditions to solve the problems mentioned in the background art. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a collaborative flow equalization electrostatic precipitator with adaptive flue gas operating conditions, comprising: A supporting frame, on one side of its upper end face, has a flue gas duct horizontally fixed to it; An air supply seat is fixed to the upper surface of the support frame and connected to the flue gas duct.

An inner tube is coaxially disposed inside the outer tube sleeve. One end of the inner tube abuts against the guide tube seat, and multiple circumferentially distributed first and second flues are provided inside the inner tube.

[0008] Furthermore, as a preferred embodiment, the first flue and the second flue are arranged in a one-to-one correspondence, and the second flue is distributed relatively close to the center of the inner tube. Each of the external channels is connected to one of the two side conventional dust removal zones, and each of the internal channels is connected to the central enhanced dust removal zone. Both the inner and outer channels are configured with arc-shaped slot structures, and the multiple first flues are respectively sealed and connected to each of the outer channels, and the second flues are respectively sealed and connected to each of the inner channels.

[0009] Furthermore, as a preferred embodiment, the inner tube is rotatably connected to the outer tube, and a central shaft is rotatably provided in the middle of the guide tube seat, one end of which passes through the guide tube seat and is fixed to the inner tube. The other end of the central shaft is fixed with an external tooth, and the electrostatic dust removal device is equipped with a bidirectional drive motor. The output end of the bidirectional drive motor meshes with the external tooth through a transmission chain.

[0010] Furthermore, as a preferred embodiment, an inner fan blade and an outer impeller are coaxially mounted on the central shaft at the flue gas inlet of the electrostatic precipitator. The inner fan blade is connected to the central shaft in a one-way clockwise rotation via a ratchet, and the outer impeller is connected to the central shaft in a one-way counterclockwise rotation via a ratchet. The blade radius of the inner fan blade is equal to the diameter of each inner channel distributed on the inner tube.

[0011] Furthermore, as a preferred embodiment, a first valve seat and a second valve seat are coaxially fixed at the ends of each of the first and second flues away from the guide pipe seat, respectively. A rotating shaft is rotatably connected between the first and second valve seats, which are distributed in the same radial direction. A first valve plate is provided in the first valve seat, and a second valve plate is provided in the second valve seat. Both the first valve plate and the second valve plate are fixed to the rotating shaft. The inner tube is rotatably connected to a connecting shaft, and a bevel gear is fixed on the connecting shaft.

The opening of the first and second valve seats in the flue gas flow control assembly is adjusted to allow the electrostatic precipitator to intelligently select the processing path based on the real-time flue gas concentration. Furthermore, the first and second flues are housed within a rotatable inner tube and are actively rotated using a bidirectional drive motor. Each flue sequentially passes through the high-speed and low-speed zones of the upstream flue section during its rotation cycle, ensuring more uniform flue gas flow in each inner (or outer) channel. This prevents spatial distribution differences in the flue gas entering the electrostatic precipitator, achieving efficient processing, precise adaptation, and energy-saving operation of the electrostatic precipitator.

[0016] Please see Figure 1 In this embodiment of the invention, a collaborative flow equalization electrostatic precipitator with adaptive flue gas operating conditions includes: A support frame 11 has a flue gas duct 1 horizontally fixed on one side of its upper end face for introducing flue gas to be treated. The air supply seat 12 is fixed to the upper end face of the support frame 11 and connected to the flue gas duct 1. Its function is to initially collect the flue gas from the flue gas duct 1 and transport it downstream. The electrostatic dust removal device 2 is installed on the outside of the support frame 11 on the side near the air supply seat 12; The flue gas flow control component 3 is installed at one end at the flue gas inlet of the electrostatic dust removal device 2. The flue gas flow control component 3 can intelligently adjust the flow direction and flow distribution of the flue gas according to the changes in flue gas conditions (such as concentration, flow rate, etc.). The other end of the flue gas flow control component 3 is sealed and connected to the air supply seat 12. The smoke exhaust duct 21 is located on one side of the upper end face of the electrostatic dust removal device 2 and is used to exhaust the purified clean gas.

[0017] In this embodiment, a dredging pipe 13 is horizontally connected between the flue gas duct 1 and the air supply seat 12. Multiple primary filters are arranged in the dredging pipe 13. These primary filters can perform preliminary filtration on the original flue gas entering the flue gas duct 1, intercept large dust particles carried therein, extend the service life of the electrostatic dust removal device 2, and also play a role in balancing the initial distribution of airflow.

[0018] In a preferred embodiment, the electrostatic dust removal device 2 has multiple sets of discharge electrodes 22 arranged vertically near the flue gas inlet, so that the dust particles in the flue gas flowing through it collide with the ion flow and attach charges in a very short time. The electrostatic dust removal device 2 also has integrated electrodes 23 distributed in it for adsorbing charged dust particles. The electrostatic precipitator 2 has two parallel partitions (not shown in the figure) vertically arranged inside. The two partitions divide the electrostatic precipitator 2 into two side conventional dust removal zones and a central enhanced dust removal zone. The surface of each partition has multiple flow holes. The side conventional dust removal zone is suitable for handling flue gas of conventional concentration, and its electric field strength and electrode configuration meet the requirements of general operating conditions. The central enhanced dust removal zone is specifically used to handle high-concentration flue gas. It can be equipped with a stronger electric field or a denser electrode structure to achieve efficient capture of high-concentration dust and achieve adaptive treatment of flue gas operating conditions.

[0019] See Figure 2 , 3 In this embodiment, the flue gas flow control component 3 includes: The guide tube seat 4 is configured in the shape of a truncated quadrangular prism, and one end of the guide tube seat 4 is sealed and fixed to the electrostatic precipitator 2. That is, the large end face of the guide tube seat 4 is sealed and fixed to the flue gas inlet side wall of the electrostatic precipitator 2, while the small end face is connected to the outer sleeve 31. This tapered truncated quadrangular prism structure design plays a role in smoothly transitioning the flue gas from the outer sleeve 31 and accelerating its introduction into the electrostatic precipitator 2, thereby reducing the generation of turbulence. Multiple inner channels 41 are provided, and each inner channel 41 is circumferentially distributed within the guide tube seat 4; The outer channel 42 is opened on the guide tube seat 4 and located on the outer periphery of the inner channel 41; The outer sleeve 31 has one end coaxially fixed with the guide tube seat 4, and the other end of the outer sleeve 31 is sealed to the air supply seat 12. The inner tube 32 is coaxially disposed inside the outer tube sleeve 31. One end of the inner tube 32 abuts against the guide tube seat 4, and multiple circumferentially distributed first flues 33 and second flues 34 are provided inside the inner tube 32.

[0020] In this embodiment, the first flue 33 and the second flue 34 are arranged in a one-to-one correspondence, and the second flue 34 is distributed relatively close to the center of the inner tube 32. Each of the outer channels 42 is connected to the two side conventional dust removal areas, thereby guiding the flue gas through the outer channels 42 to the conventional dust removal areas on both sides for treatment. Each of the inner channels 41 is connected to the central enhanced dust removal area, thereby guiding the flue gas through the inner channels 41 to the central high-efficiency treatment area. Both the inner channel 41 and the outer channel 42 are configured with an arc-shaped groove structure. The plurality of first flues 33 are respectively sealed and connected to each of the outer channels 42, and the second flues 34 are respectively sealed and connected to each of the inner channels 41.

[0021] In this embodiment, the inner tube 32 is rotatably connected to the outer tube sleeve 31, and a central shaft 43 is rotatably provided in the middle of the guide tube seat 4. One end of the central shaft 43 passes through the guide tube seat 4 and is fixed to the inner tube 32. The other end of the central shaft 43 is fixed with an external tooth. The electrostatic dust removal device 2 is equipped with a bidirectional drive motor (not shown in the figure). The output end of the bidirectional drive motor meshes with the external tooth through a transmission chain. The bidirectional drive motor can drive the central shaft 43 to rotate forward or backward according to the control signal, thereby driving the inner tube 32 to rotate in both directions within the outer tube sleeve 31. In this way, each of the first flue 33 (or second flue 34) in the rotating state can maintain a sealed connection with each of the outer channels 42 (or inner channels 41) respectively, so as to achieve uniform flow of flue gas. In traditional technology, flues are often fixed. However, the flow of flue gas in the upstream flue (such as the outlet of the air supply seat 12) is often affected by pipe bends, abrupt changes in cross-section, or fan disturbances. As a result, the velocity field is uneven in the circumferential direction. When the static flue corresponds to the upstream high-speed or low-speed zone, some flues will be in a high-flow state for a long time, while others will be in a low-flow or even backflow state. This fixed flow deviation will directly lead to inconsistent flue gas volume distribution in each downstream external channel 42 (or internal channel 41), which in turn causes the electrostatic precipitator 2 to have a "one side overloaded and one side underloaded" working condition, which seriously reduces the overall dust removal efficiency. In this device, the inner tube 32, under the control of a bidirectional drive motor, can rotate continuously in either the forward or reverse direction within the outer tube sleeve 31. Under this dynamic operating condition, each first flue 33 (or second flue 34) will sequentially pass through the high-speed zone, medium-speed zone, and low-speed zone of the upstream flue section during its rotation cycle, and send the flue gas into each of the circumferentially distributed outer channels 42 (or inner channels 41) in one go. This fundamentally eliminates the flow deviation defect, making the final flue gas flow rate obtained by each circumferentially distributed outer channel 42 (or inner channel 41) extremely small, and truly achieving uniform flue gas flow distribution.

[0022] In a preferred embodiment, an inner fan blade 44 and an outer impeller 45 are coaxially mounted on the central shaft 43 at the flue gas inlet of the electrostatic precipitator 2. The inner fan blade 44 is connected to the central shaft 43 via a ratchet, forming a unidirectional clockwise rotational engagement, and the outer impeller 45 is connected to the central shaft 43 via a ratchet, forming a unidirectional counterclockwise rotational engagement. When the central shaft 43 is driven by a motor to rotate clockwise, the inner fan blade 44 rotates synchronously with the central shaft 43 under the action of the ratchet, thereby generating an axial thrust towards the central enhanced dust removal zone, promoting the flow of flue gas towards the central zone. When the central shaft 43 rotates counterclockwise, the outer impeller 45 rotates synchronously with the central shaft 43, generating an airflow thrust towards the side conventional dust removal zone. This significantly enhances the smoothness of flue gas flow and the uniformity of distribution within the corresponding channel.

[0023] The blade radius of the inner fan blade 44 is equal to the diameter of each inner channel 41 distributed on the inner tube 4.

[0024] See Figure 4 , 5 In this embodiment, a first valve seat 51 and a second valve seat 52 are coaxially fixed at the ends of the first flue 33 and the second flue 34 away from the guide tube seat 4, respectively. A rotating shaft 5 is rotatably connected between the first valve seat 51 and the second valve seat 52, which are distributed in the same radial direction. A first valve plate 53 is provided in the first valve seat 51, and a second valve plate 54 is provided in the second valve seat 52. Both the first valve plate 53 and the second valve plate 54 are fixed to the rotating shaft 5. In this way, when the rotating shaft 5 rotates, the first valve plate 53 and the second valve plate 54 can be synchronously driven to rotate and adjust within their respective valve seats. A connecting shaft 35 is rotatably connected inside the inner tube 32. A bevel gear 36 is fixed on the connecting shaft 35. One end of each rotating shaft 5 is fixed with a driven tooth, which meshes with the bevel gear 36 for transmission. Thus, when the connecting shaft 35 is rotated for adjustment, the meshing of the bevel gear 36 with the driven tooth drives all rotating shafts 5 to rotate synchronously, thereby achieving unified and coordinated adjustment of the opening degrees of all first valve seats 51 and second valve seats 52.

[0025] In this embodiment, the first valve plate 53 and the second valve plate 54 are vertically distributed. With this arrangement, when the first valve plate 53 in the first valve seat 51 is fully closed under adjustment, the second valve plate 54 in the first valve plate 53 is fully open. The rotation of the rotating shaft 5 will increase the opening of one valve plate while decreasing the opening of the other valve plate, thereby achieving precise flow distribution control within the first valve plate 53 and the second valve plate 54.

[0026] See Figure 6In this embodiment, a positioning disk 6 is rotatably mounted concentrically at the end of the inner tube 32 away from the guide tube seat 4. One end face of the positioning disk 6 is fixed to the air supply seat 12, meaning that when the inner tube 32 rotates synchronously with the central shaft 43, the positioning disk 6 remains stationary. A steel sleeve 61 is slidably connected inside the positioning disk 6. The steel sleeve 61 is slidably fitted onto the end of the connecting shaft 35, and a pin 62 is vertically fixed on the connecting shaft 35. An arc-shaped groove is formed on the side wall of the steel sleeve 61, and the pin 62 is slidably mounted along the inner wall of the arc-shaped groove. Thus, during the axial movement of the steel sleeve 61, it can convert the linear movement of the steel sleeve 61 into the rotational movement of the connecting shaft 35. After the connecting shaft 35 obtains rotational movement, the bevel gear 36 on it rotates accordingly. Since the driven teeth at the ends of each rotating shaft 5 mesh with the bevel gear 36, all rotating shafts 5 achieve completely synchronous rotation. A thrust plate 63 is coaxially mounted on one end of the steel sleeve 61 and can rotate relative to it. A bracket is vertically fixed on the positioning plate 6, and a thrust rod 64 is hinged on the bracket. One end of the thrust rod 64 abuts against the thrust plate 63. A support spring is connected between the thrust plate 63 and the positioning plate 6, which can use its elasticity to support and push the thrust plate 63 away from the positioning plate 6 in its natural state. A propulsion cylinder 65 is also hinged on the bracket, and one end of the propulsion cylinder 65 is connected to the other end of the thrust rod 64.

[0027] This device can adaptively adjust according to a preset strategy or real-time detected flue gas concentration signal. When the concentration of the flue gas to be treated is low, the central enhanced dust removal zone is activated at low power or not at all. At this time, the piston rod of the propulsion cylinder 65 remains extended, the connecting shaft 35 is at the first angle, and the first valve plate 53 in each first valve seat 51 is fully rotated to be parallel to the airflow direction, so that the first valve seat 51 is fully opened. The second valve plate 54 in the second valve seat 52 is driven to be perpendicular to the airflow direction, so that the second valve seat 52 is fully closed. The flue gas cannot enter the inner channel 41 through the second flue duct 34 and is finally distributed to the two side conventional dust removal zones of the electrostatic precipitator 2 for conventional electrostatic dust removal. During this process, the central enhanced dust removal zone does not participate in the work, saving energy.

[0028] When an increase in flue gas concentration is detected, the retraction of the piston rod of the propulsion cylinder 65 outputs a linear thrust along the cylinder axis, thereby driving the thrust rod 64 to deflect. The thrust rod 64 pushes the thrust plate 63 towards the positioning plate 6, allowing the steel sleeve 61 to drive the connecting shaft 35 to deflect during axial sliding. This allows the propulsion cylinder 65 to rotate the connecting shaft 35 to a second angle. During the rotation from the first angle to the second angle, each first valve plate 53 gradually closes, while each second valve plate 54 gradually opens from a fully closed state. In this intermediate transition state, the flue gas is simultaneously distributed to the first flue duct 33 and the second flue duct 34; that is, a portion of the flue gas enters the side conventional dust removal area, and the other portion enters the central enhanced dust removal area, achieving coordinated treatment. When the flue gas concentration reaches an extremely high value, the steel sleeve 61 is pushed to its limit position, at which point the first valve seat 51 is completely closed, and the second valve seat 52 is completely open. All flue gas enters the inner channel 41 through the second flue 34 and is centrally introduced into the central enhanced dust removal zone for enhanced treatment; intelligent and precise flow distribution of flue gas with different concentrations under different operating conditions is realized, so that each functional area of ​​the electrostatic precipitator 2 can operate under optimal conditions, significantly improving the overall dust removal efficiency and operating economy.
