Description

Technical Field

[0001] This invention relates to the technical field of electrostatic precipitators, and particularly to an industrial electrostatic precipitator with a high-frequency pulse power supply. Background Technology

[0002] Industrial dry electrostatic precipitators are highly efficient flue gas purification devices widely used in industries such as power, metallurgy, building materials, and chemicals. Their traditional working principle involves charging dust particles through corona discharge, which are then captured and collected onto collecting electrodes under a high-voltage electric field.

[0003] However, electrostatic precipitators powered by traditional industrial frequency (50 / 60Hz) power supplies face severe challenges when handling high resistivity dust:

[0004] Back corona phenomenon: High resistivity dust layer can cause local breakdown, generating counterions, neutralizing dust charge, and severely reducing dust removal efficiency.

[0005] High energy consumption: To maintain the electric field strength, a high voltage needs to be continuously applied, resulting in low energy utilization.

[0006] Limited efficiency in capturing fine particulate matter: Traditional power supplies have large voltage fluctuations and insufficient average electric field strength, resulting in inadequate charging and capture capabilities for submicron particles. Summary of the Invention

[0007] Therefore, the purpose of this invention is to provide an industrial electrostatic precipitator with a high-frequency pulse power supply.

[0008] This invention provides the following technical solution: an industrial electrostatic precipitator with a high-frequency pulse power supply, comprising:

[0009] Housing assembly;

[0010] Anode assembly; the anode assembly is disposed inside the housing assembly;

[0011] Cathode assemblies, a plurality of said cathode assemblies being disposed inside the housing assembly;

[0012] A vibration cleaning assembly, at least one of which is disposed inside the housing assembly; the vibration cleaning assembly is used to apply vibration to the anode assembly;

[0013] A high-frequency pulse power supply system, wherein the high-frequency pulse power supply system is used to apply a composite voltage waveform to the cathode assembly;

[0014] Specifically, a composite voltage waveform is applied to the cathode component through the high-frequency pulse power supply system, thereby generating an electrostatic field between the cathode component and the anode component; flue gas enters the housing component, and the dust therein is adsorbed onto the anode component.

[0015] Furthermore, the high-frequency pulse power supply system includes:

[0016] Rectifier and filter unit: used to convert input AC power into DC power;

[0017] Full-bridge inverter unit: used to invert DC power into high-frequency square wave AC power;

[0018] High-frequency step-up transformer: Used to step up high-frequency AC power to the required high-voltage high-frequency AC power;

[0019] Special rectifier unit; used to rectify high-voltage, high-frequency AC power and output a stable negative DC base voltage;

[0020] Pulse forming network unit: used to superimpose a positive pulse with an extremely narrow width and a high peak voltage onto the DC base voltage, ultimately forming a composite voltage waveform of "DC base voltage + high frequency pulse" which is applied to the cathode assembly.

[0021] Furthermore, the vibration cleaning assembly includes: a support frame fixedly connected to the housing assembly; a plurality of sliding hammers slidably connected to the support frame; a connecting member connecting the plurality of sliding hammers together; and a drive unit for driving the plurality of sliding hammers to move and hammer the anode assembly.

[0022] Furthermore, the drive unit includes: a motor disposed on the housing assembly, a rotating shaft connected to the output shaft of the motor, at least one disk disposed on the rotating shaft, a push column disposed at an eccentric position on the disk, and a plurality of first elastic elements disposed between the support frame and the connector; the motor is started, and the drive column is driven to rotate along the axis of the rotating shaft through the rotating shaft and the disk, thereby causing the push column to push the connector to move.

[0023] Furthermore, the vibration cleaning assembly also includes a buffer and rebound unit, which includes at least one slide rod slidably connected to the support frame, and a second elastic element disposed between the slide rod and the support frame.

[0024] Furthermore, the anode assembly includes an upper fixing frame and a lower fixing frame, and a plurality of anode plates disposed between the upper fixing frame and the lower fixing frame, wherein there is a receiving space between adjacent anode plates, and the cathode assembly is located within the receiving space.

[0025] Furthermore, both the upper fixing frame and the lower fixing frame include: two first crossbeams fixedly connected to the housing assembly, and a connecting beam between the two first crossbeams corresponding to the number of anode plates; the anode plates are disposed between the connecting beams of the upper fixing frame and the lower fixing frame.

[0026] Furthermore, the anode assembly also includes a support unit for supporting the middle part of the anode plate.

[0027] Furthermore, the support unit includes: two second crossbeams fixedly connected to the housing assembly, and a plurality of limiting beams disposed between the two second crossbeams; the middle part of the anode plate is fixed between two adjacent limiting beams.

[0028] Furthermore, the cathode assembly includes: two support beams fixedly connected to the housing assembly, and a plurality of cathode wires disposed between the two support beams.

[0029] The beneficial effects of this invention are:

[0030] Improved dust removal efficiency: By adopting a high-frequency pulse power supply system, the output of a composite voltage waveform of "DC base voltage + high-frequency pulse" can effectively overcome the "back corona" phenomenon caused by high resistivity dust. The high peak pulse voltage can generate a strong corona current, which fully charges the dust, while the short-time characteristic of the pulse suppresses the generation of counterions, thereby significantly improving the collection efficiency of fine dust and high resistivity dust, and the outlet dust concentration can reach ultra-low emission standards.

[0031] Reduced system energy consumption: Compared to traditional power frequency power supplies that require continuous application of high voltage to maintain the electric field, the high-frequency pulse power supply of this invention applies a high peak voltage only within an extremely short pulse time, resulting in low average current and high energy efficiency. Simultaneously, the high-frequency inverter technology reduces the size and losses of magnetic components such as transformers, significantly lowering operating costs.

[0032] Thorough and reliable dust removal effect: The motor drives the eccentric wheel and spring energy storage mechanism to achieve instantaneous, high-acceleration hammering of the anode plate. The vibration force is large and uniform. Furthermore, the design of the buffer and rebound unit 69 further avoids the adhesion between the sliding hammer and the anode assembly. Multiple continuous slight impacts can be achieved, which makes the accumulated dust cake peel off in pieces more efficiently, effectively restoring the cleanliness of the anode plate, ensuring the stability of the electric field strength, and avoiding the decrease in efficiency caused by poor dust removal.

[0044] Example 1:

[0045] like Figure 1 and Figure 2 As shown, this embodiment of an industrial electrostatic precipitator with a high-frequency pulse power supply includes: a housing assembly 10, an anode assembly 40, a cathode assembly 50, a vibration cleaning assembly 60, and a high-frequency pulse power supply system 20.

[0046] The high-frequency pulse power supply system 20 applies a composite voltage waveform to the cathode component 50, thereby generating an electrostatic field between the cathode component 50 and the anode component 40; the flue gas enters the housing component 10, and the dust therein is adsorbed onto the anode component 40.

[0047] In this embodiment, as Figure 3 As shown, the housing assembly 10 includes: a housing 11, a support 12, an inlet 13 and an outlet 14, and an ash hopper 30;

[0048] Specifically, the support 12 is fixed in the working area, and the outer shell 11 is fixedly connected to the support 12, so that the outer shell 11 is in a suspended state. The ash hopper 30 is fixedly connected to the lower part of the outer shell 11. The dust adsorbed by the anode assembly 40 eventually falls into the ash hopper 30 and is discharged by opening the valve under the ash hopper 30. The anode assembly 40, the cathode assembly 50 and the vibration cleaning assembly 60 are all set inside the outer shell 11. The inlet 13 and the outlet 14 are respectively set on both sides of the outer shell 11. The inlet 13 is connected to the flue gas conveying equipment, and the flue gas conveying equipment inputs the flue gas into the outer shell 11 through the inlet 13.

[0049] The anode assembly 40 is disposed inside the housing assembly 10;

[0050] It is worth noting that, such as Figure 4 As shown, the anode assembly 40 includes an upper fixing frame and a lower fixing frame, and a plurality of anode plates 43 disposed between the upper fixing frame and the lower fixing frame, with a receiving space between adjacent anode plates 43, and the cathode assembly 50 is located within the receiving space.

[0051] In this embodiment, the upper fixing frame is fixedly connected to the upper part of the inner side of the outer casing 11, and the lower fixing frame is fixedly connected to the lower part of the inner side of the outer casing 11. The number of anode plates 43 can be adjusted according to the specific usage. The upper end of the anode plate 43 is fixedly connected to the upper fixing frame, and the lower end of the anode plate 43 is fixedly connected to the lower fixing frame.

[0052] It is worth noting that both the upper and lower fixing frames include: two first crossbeams 41 fixedly connected to the housing assembly 10, and connecting beams 42 corresponding to the number of anode plates 43 disposed between the two first crossbeams 41; the anode plates 43 are disposed between the connecting beams 42 of the upper and lower fixing frames.

[0053] Specifically, both ends of the first crossbeam 41 are fixedly connected to the two sides inside the outer casing 11, one end of the connecting beam 42 is fixedly connected to one of the first crossbeams 41, and the other end is fixedly connected to the other first crossbeam 41. The upper end of the anode plate 43 is fixedly connected to the connecting beam 42 of the upper fixed frame, and the lower end of the anode plate 43 is fixedly connected to the connecting beam 42 of the lower fixed frame.

[0054] Furthermore, such as Figure 4 As shown, the anode assembly 40 also includes a support unit 70, which is used to support the middle part of the anode plate 43.

[0055] Specifically, the support unit 70 includes: two second crossbeams 71 fixedly connected to the housing assembly 10, and a plurality of limiting beams 72 disposed between the two second crossbeams 71; the middle part of the anode plate 43 is fixed between two adjacent limiting beams 72.

[0056] It is worth noting that both ends of the two second crossbeams 71 are fixedly connected to the two sides inside the outer casing 11; one end of the limiting beam 72 is fixedly connected to one of the crossbeams, and the other end is fixedly connected to the other crossbeam. The number of limiting beams 72 can be adjusted according to the actual situation, and no limit is made here; the middle part of the anode plate 43 is fixed between two adjacent limiting beams 72, thereby supporting the middle part of the anode plate 43 through the supporting unit 70, improving the support performance.

[0057] Several cathode assemblies 50 are disposed inside the housing assembly 10;

[0058] In this embodiment, as Figure 5 As shown, the cathode assembly 50 includes two support beams 51 fixedly connected to the housing assembly 10, and a plurality of cathode wires 52 disposed between the two support beams 51.

[0059] Specifically, two support beams 51 are distributed on the upper and lower sides inside the outer shell 11. The two ends of the support beams 51 are fixedly connected to the inner sides of the outer shell 11, and the connection between the support beams 51 and the outer shell 11 is made of insulating material. The number of cathode wires 52 can be adjusted according to the actual situation, and no limit is made here. The upper end of the cathode wire 52 is fixedly connected to the upper support beam 51, and the other end is fixedly connected to the lower support beam 51.

[0060] like Figure 6 and Figure 7 As shown, at least one vibration cleaning assembly 60 is disposed inside the housing assembly 10; the vibration cleaning assembly 60 is used to apply vibration to the anode assembly 40.

[0061] In this embodiment, the vibration cleaning assembly 60 includes: a support frame 61 fixedly connected to the housing assembly 10; a plurality of sliding hammers 62 slidably connected to the support frame 61; a connector 63 connecting the plurality of sliding hammers 62 together; and a drive unit for driving the plurality of sliding hammers 62 to move and hammer the anode assembly 40.

[0062] It is worth noting that in this embodiment, three sets of vibration cleaning components 60 are provided, located at the upper, middle, and lower positions inside the outer shell 11, respectively. The upper vibration cleaning component 60 is used to beat the upper fixed frame, the middle one is used to beat the support unit 70, and the lower one is used to beat the lower fixed frame. The support frame 61 is fixedly connected to the inner side of the outer shell 11. In this embodiment, three sliding hammers 62 are slidably connected to the support frame 61. The ends of the three sliding hammers 62 are fixedly connected to each other through the connector 63. The driving unit is used to drive the three sliding hammers 62 to move simultaneously and make the sliding hammers 62 vibrate the anode component 40 instantaneously, shaking the dust adsorbed on the anode component 40 into the ash hopper 30.

[0063] In this embodiment, the drive unit includes: a motor 65 disposed on the housing assembly 10, a rotating shaft 66 connected to the output shaft of the motor 65, at least one disk 67 disposed on the rotating shaft 66, a push column 68 disposed at an eccentric position on the disk 67, and a plurality of first elastic members disposed between the support frame 61 and the connector 63; when the motor 65 is started, the drive column 68 is driven to rotate along the axis of the rotating shaft 66 through the rotating shaft 66 and the disk 67, thereby causing the push column 68 to push the connector 63 to move;

[0064] It is worth noting that the motor 65 is a geared motor, which is fixedly connected to the outer wall of the housing 11. One end of the rotating shaft 66 is rotatably connected to the inner side of the housing 11, and the other end passes through the side wall of the housing 11 and is fixedly connected to the output shaft of the motor 65. In this embodiment, two discs 67 are provided, both of which are fixedly connected to the rotating shaft 66 and are coaxially arranged with the rotating shaft 66. The two discs 67 are distributed on both sides of the rotating shaft 66, and the connecting piece 63 is located between the two discs 67. The push column 68 is rotatably connected to the eccentric position of both discs 67. The first elastic element is a first spring 64, one end of which is fixedly connected to the support frame 61, and the other end is fixedly connected to the connecting piece 63. The first spring 64 is sleeved on the sliding hammer 6. In this embodiment, the number of first springs 64 on the outer wall of component 2 corresponds to the number of sliding hammers 62. It can be understood that when the operator starts the motor 65, the motor 65 drives the rotating shaft 66 to rotate, the rotating shaft 66 drives the disc 67 to rotate, and the disc 67 drives the pushing column 68 to rotate. When the pushing column 68 rotates to contact the connector 63, it pushes the connector 63 to move away from the anode assembly 40. The sliding hammers 62 move with the connector 63. At this time, the first springs 64 are stretched. When the pushing column 68 rotates to disengage from the connector 63, the first springs 64 will instantly reset, causing the sliding hammers 62 to instantly reset, thereby causing the sliding hammers 62 to instantly strike the anode assembly 40, generating instantaneous vibration, and shaking off the dust adsorbed on the anode assembly 40.

[0065] High-frequency pulse power supply system 20, which is used to apply a composite voltage waveform to cathode assembly 50;

[0066] In this embodiment, the high-frequency pulse power supply system 20 includes:

[0067] Rectifier and filter unit: used to convert input AC power into DC power;

[0068] Specifically, the rectifier and filter unit is used to convert the input three-phase power frequency AC power into smooth DC power;

[0069] Full-bridge inverter unit: used to invert DC power into high-frequency square wave AC power;

[0070] It is understandable that full-bridge inverter units use switching devices such as high-frequency insulated-gate bipolar transistors to convert DC power into high-frequency square-wave AC power of 20kHz-50kHz. High-frequency conversion reduces equipment size and improves response speed.

[0071] High-frequency step-up transformer: Used to step up high-frequency AC power to the required high-voltage high-frequency AC power;

[0072] Specifically, high-frequency step-up transformers are used to boost high-frequency alternating current to the required high voltage. It's worth noting that due to the high operating frequency, the transformer's size and weight can be reduced by 60%-70%.

[0073] Special rectifier unit; used to rectify high-voltage, high-frequency AC power and output a stable negative DC base voltage;

[0074] Specifically, the special rectifier unit is used to rectify the boosted high-frequency AC power and output a stable negative DC base voltage, preferably -40kV to -50kV.

[0075] Pulse forming network unit: used to superimpose a positive pulse with an extremely narrow width and a high peak voltage onto the DC base voltage, ultimately forming a composite voltage waveform of "DC base voltage + high frequency pulse" which is applied to the cathode assembly 50.

[0076] Specifically, the pulse forming network unit is used to superimpose a positive pulse with an extremely narrow width and a high peak voltage onto the DC base voltage through capacitor charging and discharging and high-speed switching; ultimately forming a composite voltage waveform of "DC base voltage + high-frequency pulse" which is applied to the cathode line 52.

[0077] Example 2:

[0078] like Figure 6 and Figure 7 As shown, the difference between this embodiment and the first embodiment is that the vibration cleaning assembly 60 further includes a buffer and shock absorption unit 69, which includes at least one slide rod 691 slidably connected to the support frame 61, and a second elastic member disposed between the slide rod 691 and the support frame 61.

[0079] Specifically, the support frame 61 has two sliding rods 691 connected in a sliding manner, and the second elastic element is a second spring 692. One end of the second spring 692 is fixedly connected to the sliding rod 691, and the other end of the second spring 692 is fixedly connected to the support beam 51. The second spring 692 is sleeved on the outer wall of the sliding rod 691.

[0080] It can be understood that the working principle of this embodiment is as follows: when the motor 65 starts, the push column 68 rotates with the disk 67 and pushes the connector 63, causing all the slide hammers 62 to overcome the tension of the first spring 64 and move away from the anode assembly 40 (this is the energy storage process).

[0081] Subsequently, at the moment when the push column 68 rotates past its highest point and disengages from the connector 63, the tension of the first spring 64 loses its resistance and will rapidly pull the connector 63 and the slide 62 back toward the anode assembly 40, causing the slide 62 to violently strike the anode plate 43, thus completing one main cleaning action.

[0082] As the connector 63 is pulled back by the first spring 64, it will first collide with the end of the extended slide bar 691. The collision will push the slide bar 691 backward by the elastic force of the second spring 692, that is, compress it into the support frame 61.

[0083] Immediately afterwards, the compressed second spring 692 stores energy and generates a rebound force, which acts in the opposite direction on the connector 63 through the slide rod 691, which is equivalent to applying a brief, reverse thrust or vibration to the connector 63.

[0084] In summary, by setting up the buffer rebound unit, it can be ensured that the hammer head of the slide hammer 62 can immediately separate from the surface of the anode assembly after impact, preventing the "sticking" or "sucking" phenomenon caused by dust stickiness or vacuum effect, and preparing for the next hammering.

[0085] It can also trigger secondary micro-vibrations: the reverse thrust will be transmitted to the entire anode assembly, which may cause a secondary slight vibration of the anode assembly, which helps to loosen the dust that has not yet fallen off after the first main impact and is in a critical state, thereby further improving the thoroughness of dust removal.

[0086] In summary, the present invention can achieve the following effects:

[0087] Improved dust removal efficiency: Utilizing a high-frequency pulse power supply system, the output features a composite voltage waveform of "DC base voltage + high-frequency pulse," effectively overcoming the "back corona" phenomenon caused by high-resistivity dust. The high-peak pulse voltage generates a powerful corona current, fully charging the dust particles. Simultaneously, the short-duration nature of the pulse suppresses the generation of counterions, thus significantly improving the collection efficiency for fine dust (such as PM2.5) and high-resistivity dust. The outlet dust concentration can be stably kept below 10 mg / m³. 3 Ultra-low emission standards.

[0088] Reduced system energy consumption: Compared to traditional power frequency power supplies that require continuous application of high voltage to maintain the electric field, the high-frequency pulse power supply of this invention applies a high peak voltage only within an extremely short pulse time, resulting in low average current and high energy efficiency. Simultaneously, the high-frequency inverter technology reduces the size and losses of magnetic components such as transformers, achieving a system power factor of over 0.95 and a comprehensive energy-saving effect of 30%-80%, significantly reducing operating costs.

[0089] Thorough and reliable dust removal effect: The motor drives the eccentric wheel and spring energy storage mechanism to achieve instantaneous, high-acceleration hammering of the anode plate. The vibration force is large and uniform. Furthermore, the design of the buffer and rebound unit 69 further avoids the adhesion between the sliding hammer and the anode assembly. Multiple continuous slight impacts can be achieved, which makes the accumulated dust cake peel off in pieces more efficiently, effectively restoring the cleanliness of the anode plate, ensuring the stability of the electric field strength, and avoiding the decrease in efficiency caused by poor dust removal.
