Description

Technical Field

[0001] This utility model relates to the field of dust collectors, and more specifically, to a multi-stage composite electrostatic precipitator. Background Technology

[0002] An electrostatic precipitator is a device used for air purification. It primarily uses the principle of electrostatic force to remove fine particulate matter (such as dust, smoke, and particulate matter) from the airflow. It is widely used in industrial fields, especially in areas such as flue gas emissions and air pollution control, to reduce harmful particulate matter emissions and protect the environment. Under the influence of an electric field, particles are attracted by the electricity and adhere to the electrode plates. The cleaned air, after being treated for dust removal, is then discharged into the external environment.

[0003] However, most electrostatic precipitators currently suffer from the following problems:

[0004] For example, an electrostatic precipitator with publication number 202320218189.6, although capable of adsorbing dust in the gas through installed dust collection electrodes, relies solely on these electrodes for dust removal, resulting in poor effectiveness. Dust adheres to the electrodes, creating a dust layer that hinders electrostatic adsorption and leads to uneven dust removal, impacting performance and hindering uniform multi-stage filtration. Similarly, a wet electrostatic precipitator with publication number 202320272199.8, while using fixed electrode plates to improve dust removal stability, is prone to damage over time, affecting dust removal efficiency and potentially causing malfunction. The electrode plate is a core component of the electrostatic precipitator, directly influencing the strength and uniformity of the electric field. Deformation or damage weakens the electric field. Replacing damaged plates requires cutting the connection points with tools, making disassembly and replacement cumbersome and hindering convenient installation and removal.

[0005] Therefore, we made improvements and proposed a multi-stage composite electrostatic precipitator. Utility Model Content

[0006] The purpose of this invention is to address the current problems of inconvenience in uniformly filtering and removing dust, as well as the inconvenience in conveniently disassembling and installing electrode plates.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] Multi-stage composite electrostatic precipitators are used to improve the above-mentioned problems.

[0009] The application is as follows:

[0010] The device includes a housing, an air inlet pipe fixedly connected to the housing, an air outlet pipe fixedly connected to the housing, an insulating frame inside the housing, an electrode plate fixedly connected to the insulating frame, a sealing gasket fixedly connected to the housing, a limit frame fixedly connected to the insulating frame, a limit frame on the housing, a guide block fixedly connected to the limit frame, the guide block being slidably connected to the housing, a spring fixedly connected inside the guide block, a limit plate fixedly connected to the other end of the spring, a positioning block fixedly connected to the limit plate, a pull rod fixedly connected to the limit plate, a filter screen fixedly connected inside the housing, dehumidifying particles disposed below the filter screen, an activated carbon plate fixedly connected inside the housing, a first sealing cover bolted to the housing, a motor fixedly connected to the housing, a reciprocating screw fixedly connected to the output shaft of the motor, the reciprocating screw being rotatably connected to the housing, a connecting frame threadedly connected to the reciprocating screw, and a slide rod slidably connected to the upper limit of the connecting frame.

[0011] As a preferred technical solution of this application, the insulating frames are evenly distributed in the box, and the insulating frames correspond one-to-one with the limiting frames through the electrode plates. The cross-sections of the limiting frames and the guide blocks are "T" shaped, and the height of the bottom end face of the air intake pipe is greater than the height of the top end face of the insulating frame.

[0012] As a preferred technical solution of this application, the side end face of the limiting plate is in contact with the inner side face of the guide block, the length of the positioning block is less than the length of the pull rod, and one end of the pull rod is fixedly connected to the center part of one side of the limiting plate.

[0013] As a preferred technical solution of this application, the guide blocks are symmetrically distributed on the left and right sides of the limiting frame, and the guide blocks correspond one-to-one with the positioning blocks through the limiting plates. The cross-section of the filter screen is inverted "U" shape, and the output shaft of the motor is fixedly connected to the center of one end of the reciprocating lead screw.

[0014] As a preferred technical solution of this application, the slide bar is fixedly connected to the box body, a first scraper is fixedly connected to the connecting frame, a second scraper is fixedly connected to the first scraper, and the top surface of the connecting frame is in contact with the top surface of the box body.

[0015] As a preferred technical solution of this application, a collection box is fixedly connected to the box body, a second sealing cover is bolted to the collection box, an insulating pad is fixedly connected to the box body, and the side of the second scraper is inclined.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the scheme of this application:

[0018] 1. Equipped with a reciprocating lead screw; when cleaning dust from the electrode plate and filter screen, the motor can be turned on to drive the reciprocating lead screw to rotate. When the reciprocating lead screw pushes the connecting frame to move, the connecting frame can move smoothly with the support of the sliding rod. When the connecting frame moves, it can drive the first scraper to move. The first scraper can clean the dust adsorbed on the electrode plate. When it reaches the edge, it can be insulated by the insulating frame to prevent the dust from being unable to be discharged. When the first scraper drives the second scraper to move reciprocally, the second scraper can scrape off the dust on the filter screen and scrape the dust into the collection box for centralized collection, so as to avoid the accumulation of dust affecting the dust removal effect of the filter plate.

[0019] 2. A limiting frame is installed; when replacing a damaged electrode plate, the pull rods on the guide blocks on both sides can be pulled. The pull rods drive the limiting plate to move, and at the same time, the limiting plate can compress the spring. The limiting plate drives the positioning block to detach from the box and retract into the guide block. The guide block is unobstructed and can slide to detach from the box. The limiting frame can then be disassembled. After the limiting frame is removed, the limiting frame is unobstructed, and the corresponding insulating frame and electrode plate can be disassembled and replaced to avoid the damaged electrode plate affecting the dust removal effect.

A positioning block 12 is fixedly connected to the limiting plate 11. A pull rod 13 is fixedly connected to the limiting plate 11. A filter screen 14 is fixedly connected inside the box 1. Dehumidifying particles 15 are set below the filter screen 14. An activated carbon plate 16 is fixedly connected inside the box 1. A first sealing cover 17 is bolted to the box 1. A motor 18 is fixedly connected to the box 1. A reciprocating screw 19 is fixedly connected to the output shaft of the motor 18. The reciprocating screw 19 is rotatably connected inside the box 1. A connecting frame 20 is threadedly connected to the reciprocating screw 19. A slide rod 21 is slidably connected to the upper limit of the connecting frame 20.

[0037] Example 2:

[0038] The solution in Example 1 will be further described below with reference to its specific working method.

[0039] like Figure 5 As shown, in a preferred embodiment, based on the above method, the side end face of the limiting plate 11 is further fitted with the inner side face of the guide block 9, the length of the positioning block 12 is less than the length of the pull rod 13, one end of the pull rod 13 is fixedly connected to the center part of one side of the limiting plate 11, the insulating frame 4 is evenly distributed in the box 1, the insulating frame 4 corresponds one-to-one with the limiting frame 7 through the electrode plate 5, the cross-section of the limiting frame 7 and the guide block 9 is "T" shaped, the height of the bottom end face of the air inlet pipe 2 is greater than the height of the top end face of the insulating frame 4, which can ensure that the "T" shaped guide block 9 can slide in the upper limit of the box 1, and the "T" shaped limiting frame 7 can be pressed and limited by the limiting frame 8.

[0040] like Figure 2 As shown, in a preferred embodiment, based on the above method, the guide blocks 9 are symmetrically distributed on the left and right sides of the limiting frame 8. The guide blocks 9 correspond one-to-one with the positioning blocks 12 through the limiting plate 11. The filter screen 14 has an inverted "U" shape in cross-section. The output shaft of the motor 18 is fixedly connected to the center of one end of the reciprocating screw 19, which can ensure that the inverted "U" shaped filter screen 14 can clean the dust while filtering the gas in the collection box 24 at the same time.

[0041] like Figure 6As shown, in a preferred embodiment, based on the above method, a collection box 24 is fixedly connected to the box body 1, a second sealing cover 25 is bolted to the collection box 24, an insulating pad 26 is fixedly connected to the box body 1, the side of the second scraper 23 is inclined, the slide rod 21 is fixedly connected inside the box body 1, a first scraper 22 is fixedly connected to the connecting frame 20, a second scraper 23 is fixedly connected to the first scraper 22, and the top surface of the connecting frame 20 is in contact with the top surface inside the box body 1, which can ensure that the connecting frame 20 can move smoothly by being supported by the contact of the top surface inside the box body 1 when it reciprocates.

[0042] Specifically, when using this multi-stage composite electrostatic precipitator: combine with... Figure 1-9 The gas is delivered to the chamber 1 through the inlet pipe 2. When the electrode plate 5 is connected to an external power source, the wiring can be inserted through the insulating pad 26. When the gas passes through the electrode plate 5, it can remove dust by electrostatic attraction. If dust remains in the gas, it can be filtered a second time through the filter screen 14. The desiccant particles 15 at the bottom of the filter screen 14 can filter and adsorb the humid gas in the gas. The activated carbon plate 16 at the bottom can purify the gas. Multi-stage filtration can perform sufficient dust removal and filtration. When the desiccant particles 15 need to be replaced, the first sealing cover 17 on the chamber 1 can be removed to replace the desiccant particles 15. The treated gas can be discharged through the outlet pipe 3.

[0043] When cleaning the dust on the electrode plate 5 and the filter screen 14, the motor 18 can be turned on to drive the reciprocating screw 19 to rotate. When the reciprocating screw 19 pushes the connecting frame 20 to move, the connecting frame 20 can move smoothly with the support of the slide rod 21. When the connecting frame 20 moves, it can drive the first scraper 22 to move. The first scraper 22 can clean the dust adsorbed on the electrode plate 5. When scraping to the edge, it can be insulated by the insulating frame 4 to prevent the dust from being unable to be discharged. When the first scraper 22 drives the second scraper 23 to move back and forth, the second scraper 23 can scrape off the dust on the filter screen 14 and scrape the dust into the collection box 24 for centralized collection to prevent the accumulation of dust from affecting the dust removal effect of the filter plate. When cleaning the dust in the collection box 24, the second sealing cover 25 on the collection box 24 can be removed to clean and collect the dust.

[0044] When replacing the damaged electrode plate 5, the pull rod 13 on both sides of the guide block 9 can be pulled. The pull rod 13 drives the limiting plate 11 to move. At the same time, the limiting plate 11 can squeeze the spring 10. The limiting plate 11 drives the positioning block 12 to detach from the box 1 and return to the guide block 9. The guide block 9 is unobstructed and can slide off the box 1. The limiting frame 8 can be disassembled. After the limiting frame 8 is removed, the limiting frame 7 is unobstructed. The insulating frame 4 corresponding to the limiting frame 7 and the electrode plate 5 can be disassembled and replaced. After installation and reset, the guide block 9 is locked in the box 1. The pull rod 13 is released and the limiting plate 11 and the positioning block 12 are reset under the push of the spring 10. The positioning block 12 is locked in the box 1 for limiting and fixing. The limiting frame 8 prevents the limiting frame 7 from shaking and falling off. The limiting frame 7 is protected by the sealing gasket 6 to prevent air leakage and prevent the damaged electrode plate 5 from affecting the dust removal effect.
