Description

Technical Field

[0001] This application belongs to the field of electrostatic dust removal technology, and more specifically, relates to an electrostatic dust removal device. Background Technology

[0002] Electrostatic precipitators are a commonly used technology in industrial waste gas treatment and air purification. With their high particulate matter capture capacity and stable operating characteristics, they can better purify high-concentration dust waste gas emitted from industrial production and reduce the content of air pollutants. Compared with other dust removal methods, they have advantages such as low energy consumption, long maintenance cycle and wide applicability.

[0003] Patent application number 2022219798460 discloses a high-voltage electrostatic dust removal device, relating to the field of electrostatic dust removal. It includes a collection base box with a drawer slot horizontally opened on one side. A sealing panel is horizontally engaged on the inner side of the drawer slot. A feed pipe is horizontally welded to the outer side of the collection base box. A guide pipe is vertically welded upwards to the top surface of the collection base box. A processing pipe is vertically welded upwards to the top of the guide pipe. A fixing box is bolted to the outer side of the processing pipe. An air inlet pipe is horizontally welded to the outer side of the processing pipe. The high-voltage electrostatic structure allows for efficient and rapid adsorption of dust inside the gas. Simultaneously, a vibration structure allows the dust adsorbed on the plate to be shaken off, facilitating subsequent collection and processing. The water spray structure further enhances the comprehensive dust treatment. The integrated sealed structure prevents dust from polluting the outside.

[0004] The above solution has shortcomings in use. Using vibration to adsorb the inner plate to remove dust causes the dust to scatter inside the treatment tube. The scattered dust will form secondary dust in the tube and will take a long time to completely fall into the drawer. This greatly increases the time required to clean the dust on the adsorption inner plate, causing the electrostatic dust removal work to stop for a long time. This makes it impossible to treat the dust-laden exhaust gas in a timely manner, thus affecting the efficiency of the electrostatic dust removal work. Therefore, we provide an electrostatic dust removal device. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide an electrostatic dust removal device.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: An electrostatic dust removal device is provided, comprising: a housing, wherein a dust collection plate capable of generating a high-voltage electric field is provided inside the housing, an air inlet pipe and an air outlet pipe are provided on the housing, and an anti-dust-scattering cleaning device is provided inside the housing, the anti-dust-scattering cleaning device comprising a scraper, a dust suction component and a driving component; the driving component drives the scraper to reciprocate along the surface of the dust collection plate, and the dust suction component absorbs and collects the dust scraped off by the scraper.

[0007] In one embodiment, two dust collection plates are spaced apart and the dust accumulation surfaces of the two dust collection plates are arranged close to each other. Two scrapers are provided and the two scrapers are located between the two dust collection plates.

[0026] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0030] like Figures 1-5 As shown, an electrostatic dust removal device provided in this application embodiment will now be described. This electrostatic dust removal device includes a housing 1, inside which is a dust collection plate 2 capable of generating a high-voltage electric field; the housing 1 also has an inlet pipe 3 and an outlet pipe 4. Gas can enter the housing 1 through the inlet pipe 3. Then, the dust collection plate 2 is connected to a power source, forming a high-voltage electric field around it. Dust particles in the gas are ionized under the influence of the electric field, becoming charged particles. Under the influence of the electric field, the charged dust particles move towards the dust collection plate 2. The dust collection plate 2 carries a charge opposite to that of the dust particles. According to the principle of opposite charges attracting, the dust particles are adsorbed onto the surface of the dust collection plate 2, thereby achieving the adsorption and separation of dust in the gas, purifying the gas. The purified gas is then discharged from the outlet pipe 4. A gas diversion hood 6 is fixedly connected to the inner wall of the shell 1. The gas diversion hood 6 is an inverted funnel structure. The top of the gas diversion hood 6 is connected to the bottom of the gas outlet pipe 4. The gas diversion hood 6 can be used to divert the purified gas to prevent the gas from accumulating and remaining inside the shell 1.

[0031] like Figures 1-5 As shown, the housing 1 is equipped with an anti-dust-scattering device 5, which includes a scraper 501, a dust collection component, and a drive component. The scraper 501 is attached to the dust-accumulating surface of the dust collection plate 2. The drive component drives the scraper 501 to reciprocate along the surface of the dust collection plate 2 to scrape off the dust adsorbed on the surface of the dust collection plate 2. The dust collection component absorbs and collects the dust scraped off by the scraper 501.

[0032] Specifically, two dust collection plates 2 are spaced apart, and the dust accumulation surfaces of the two dust collection plates 2 are arranged close to each other. Two scraper blades 501 are also spaced apart, and the two scraper blades 501 are arranged between the two dust collection plates 2 to scrape the dust from the corresponding dust collection plates 2.

[0033] In this embodiment, the dust collection assembly includes: a dust collection box 504, a suction pump 505, a suction pipe 502, a U-shaped pipe 503, a telescopic pipe 507, and a dust conveying pipe 506. The dust collection box 504 is disposed on the inner bottom surface of the housing 1. One end of the dust conveying pipe 506 is connected to the top side of the dust collection box 504, and the other end is connected to the suction pump 505. The suction pump 505 is connected to one end of the telescopic pipe 507, and the other end of the telescopic pipe 507 is connected to the middle outlet of the U-shaped pipe 503. Both ends of the U-shaped pipe 503 are closed. Multiple suction pipes 502 are spaced apart and fixed to the scraper 501. One end of each suction pipe 502 faces the dust collection plate 2, and the other end is connected to the U-shaped pipe 503. Multiple suction pipes 502 are evenly spaced on each scraper 501. When the drive assembly moves the scraper 501 along the dust collection plate 2, the suction pump 505 operates, generating suction and creating a negative pressure at the suction pipes 502. This causes the scraped dust to pass through the suction pipes 502, U-shaped pipe 503, telescopic pipe 507, suction pump 505, and dust conveying pipe 506 before being discharged into the dust collection box 504 for collection. The telescopic pipe 507 is used to accommodate the movement of the scraper 501. The telescopic pipe 507 can also be replaced by a flexible hose, with a length greater than the stroke of the scraper 501. By using the dust collection assembly to prevent dust from scattering in the housing 1, the dust removal time of the dust collection plate 2 can be accelerated, further shortening the downtime of the dust collection plate 2. This allows for timely treatment of subsequent dust-laden exhaust gas, thereby ensuring the efficiency of electrostatic dust removal.

[0034] like Figures 3-5As shown, a dust collection frame 508 is provided inside the dust collection box 504. The dust collection frame 508 is detachably installed inside the dust collection box 504 and can be removed from the dust collection box 504. Specifically, an installation port is provided at the bottom of the housing 1. The bottom plate edge of the dust collection frame 508 is connected to the bottom plate of the housing 1 by several bolts, allowing the dust collection frame 508 to be inserted into the dust collection box 504 through the installation port. Alternatively, the housing 1 is provided with an openable and closable sealing door, which allows the integrated frame 508 to be placed in the dust collection box by opening the sealing door. Inside 504; the dust collection frame 508 can be used to collect the suctioned dust, and then the staff can turn the bolts to separate the dust collection frame 508 from the dust collection box 504, so that the staff can easily handle the collected dust. The inner wall of the dust collection box 504 is fixedly connected to the dust hopper guide hood 509. The dust hopper guide hood 509 has a funnel-shaped structure and is located above the dust collection frame 508. The dust hopper guide hood 509 can guide the collected dust to ensure that all the dust falls into the dust collection frame 508.

[0035] like Figures 2-4 As shown, the upper parts of the two scrapers 501 are connected together by a movable plate 512. The drive assembly includes a motor 510 and a lead screw 511. The motor 510 is fixed inside the housing 1. One end of the lead screw 511 is rotatably mounted on the housing 1, and the other end is connected to the output shaft of the motor 510. The lead screw 511 is threadedly connected to the movable plate 512. The operation of the motor 510 will drive the lead screw 511 to rotate, which in turn drives the movable plate 512 to move. At the same time, the movable plate 512 will pull the scrapers 501 to move against the dust collection plate 2, thus completing the comprehensive scraping of dust on the dust collection plate 2. The housing 1 contains two guide plates 513, and the lower part of each scraper 501 is slidably connected to the corresponding guide plate 513. Each scraper 501 is slidably connected to a guide plate 513, and the front and rear ends of each guide plate 513 are connected to the inner wall of the housing 1. The guide plates 513 guide the scraper 501, allowing it to move smoothly against the dust collection plate 2, further ensuring the cleaning effect of the scraper 501 on the dust collection plate 2. At least one blocking block 514 is provided on each side of the moving plate 512. Specifically, a set of blocking blocks 514 is embedded on the same side of the moving plate 512. The set of blocking blocks 514 is symmetrically arranged, and the blocking blocks 514 can limit the end point of the stroke of the scraper 501, preventing the scraper 501 from causing the U-shaped tube 503 to collide with the housing 1.

[0036] Working principle: When cleaning dust on the dust collection plate 2, the motor 510 and the suction pump 505 are started and work synchronously. The motor 510 drives the lead screw 511 to rotate, and at the same time, the moving plate 512 pulls the scraper 501 to move against the dust collection plate 2, which can scrape off the dust on the dust collection plate 2. At the same time, the pump body 505 will suck the inside of the U-shaped tube 503 through the telescopic tube 507. The end of the suction tube 502 near the dust collection plate 2 will generate negative pressure, which will suck up the scraped dust and transport the dust to the dust collection box 504 through the U-shaped tube 503, the telescopic tube 507 and the dust conveying pipe 506, thereby preventing the dust from floating in the housing 1, which can speed up the dust removal time of the dust collection plate 2, further shorten the downtime of the dust collection plate 2, and enable timely treatment of subsequent dust-laden exhaust gas, thereby ensuring the efficiency of electrostatic dust removal.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
