Description

Technical Field

[0001] This invention belongs to the field of electrostatic dust removal technology, and particularly relates to an electrostatic waste gas dust removal device. Background Technology

[0002] In the field of industrial flue gas purification, electrostatic precipitators are widely used due to their efficient removal of fine dust and aerosols. These precipitators typically consist of multiple vertically arranged electrostatic adsorption tubes (or collecting tubes), with high-voltage electrodes inside to generate a strong electric field. When dust-laden gas flows through the electrostatic adsorption tubes, the dust particles become charged under the influence of the electric field and tend towards the tube wall, eventually being adsorbed and deposited on the inner wall of the tube to form a dust layer. This achieves the effect of dust removal from waste gas.

[0003] In existing technology (publication number CN210171684U, patent application titled "Wet Electrostatic Precipitator with Packing Pre-Dust Removal"), the bottom of the wet electrostatic precipitator is equipped with a spray and packing structure to perform preliminary dust removal on the flue gas before it enters the wet electrostatic precipitator, thereby improving the dust removal efficiency of the wet electrostatic system and reducing its energy consumption. However, in implementing this technical solution, at least the following problems were found in the existing technology.

[0004] In the aforementioned patent, during the operation of the exhaust gas dust collector, some particles in the exhaust gas are adsorbed. As the operating time increases, the dust layer accumulated on the pipe wall will continue to thicken. Although the spray system above the dust collector can achieve some removal effect, it is easier to leave residues for wet dust with high viscosity in the exhaust gas. Moreover, fixed rinsing may consume a large amount of water. Therefore, there is an urgent need for an improved technical solution that can overcome the above defects, especially to solve the problem of cleaning the dust accumulation inside the electrostatic adsorption pipe.

At the same time, a scraping mechanism for scraping the inner wall of the electrostatic adsorption tube is driven by the electrode frames.

[0007] Preferably, the electrostatic adsorption tube has a lower box and an upper box at its upper and lower openings, respectively. Electrode boxes are fixed on the outer surfaces of the lower box and the upper box, and the ceramic bottle column connected to the electrode frame is placed inside the electrode box.

[0008] Preferably, a motor is fixed to the outer surface of the lower housing and the upper housing respectively, and the motor is located between two adjacent porcelain insulator columns. A lifting link is fixed below the two porcelain insulator columns, and a threaded sleeve is fixed at the center above the outer surface of the lifting link. At the same time, a threaded rod is fixed at the output end below the motor, and the end of the threaded rod extends to the threaded sleeve.

[0009] Preferably, the scraping mechanism consists of a scraping ring whose outer ring abuts against the inner ring wall of the electrostatic adsorption tube, and a connecting ring is sleeved on the outer circumferential surface of the electrode wire. The connecting ring and the scraping ring are connected by a connecting rod.

[0010] Preferably, the scraping rings are equidistantly distributed on the inner ring wall of the electrostatic adsorption tube, and adjacent connecting rings are connected by connecting rods. A connecting plate is fixed on the bottom surface of the electrode frame, and the bottom surface of the connecting plate is connected to the end of the connecting rod.

[0011] Preferably, the scraping mechanism is composed of a scraper that is attached to the inner ring wall of the electrostatic adsorption tube. The scraper extends downward from the upper opening of the electrostatic adsorption tube, and the scrapers are connected and fixed to each other by a connecting ring.

[0012] Preferably, a rotating ring is sleeved on the outer circumferential surface of the electrode wire above the electrostatic adsorption tube, and the lower edge of the rotating ring is connected to the top of the scraper by a connecting rod 2. At the same time, an inclined guide groove is provided on the outer circumferential surface of the rotating ring.

[0013] Preferably, the outer peripheral surface of the second connecting rod is fixed with a collar that fits into the opening of the electrostatic adsorption tube, the bottom surface of the electrode frame is fixed with a second connecting plate, and a push rod extends downward from one side of the bottom surface of the second connecting plate. The outer surface of the push rod is in contact with the rotating ring, and a protrusion on one side of the outer surface of the push rod extends to the guide groove.

[0014] Preferably, a collection tower is fixed to the bottom surface of the lower housing. The collection tower has a downward-facing recessed structure, and a rotating hole is opened downward on the upper surface of the collection tower. A rotatable filter cylinder is located at the center of the rotating hole, and a collection cylinder is also fixed to the bottom surface of the collection tower.

[0015] Preferably, a toothed ring is fixed to the bottom surface of the filter cylinder, which meshes with a gear on one side of the outer circumference of the collection cylinder.

[0016] The electrostatic exhaust gas dust removal device of the present invention has the following advantages:

[0017] 1. This electrostatic exhaust gas dust removal device, when exhaust gas needs to be dusted, the exhaust gas enters the interior of the upper chamber through the air inlet, and then is sprayed by the spray system. During the spraying process, the motor drives the electrode frame to move together.

As the electrode frame moves downward, the electrode frame pushes the top rod to move the bottom plate out from the opening of the filter cylinder, and then the particulate impurities inside the filter cylinder fall off, making it convenient to clean the inside of the filter cylinder.

Detailed Implementation

[0036] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1-5The image shows a first embodiment of this application. The electrostatic exhaust gas dust removal device in this embodiment consists of a lower housing 1 and an electrostatic adsorption tube 11 disposed above the lower housing 1. The electrostatic adsorption tube 11 is formed by multiple sets of tubular tubes arranged side-by-side. An upper housing 12 is fixed to the opening above the electrostatic adsorption tube 11. An air inlet 13 is also provided at the top of the upper housing 12 for air intake. This air inlet 13 connects to an exhaust gas pipe, allowing the exhaust gas to enter the interior of the upper housing 12 and pass through the electrostatic adsorption tubes 11. An exhaust port 14 is also provided on one side of the outer surface of the lower housing 1 for exhausting exhaust gas.

[0038] Meanwhile, a spray system 15 is fixed inside the upper housing 12 above the electrostatic adsorption tube 11. The spray system 15 can spray the inside of the dust removal device, causing the particulate impurities adsorbed on the inner ring wall of the electrostatic adsorption tube 11 to fall off. Furthermore, electrode frames 17 capable of synchronous displacement are respectively provided at the upper and lower openings of the electrostatic adsorption tube 11. The two ends of the electrode wire 18 used for discharge are connected to the electrode frames 17 respectively, and the electrode wire 18 passes through the center of the electrostatic adsorption tube 11. The connection between the electrode frame 17 and the electrode wire 18 is connected by a spring 181, keeping the electrode wire 18 taut to prevent it from loosening and causing poor corona discharge effect.

[0039] Electrode boxes 121 are fixed on the outer surfaces of the lower box 1 and the upper box 12, respectively. The ceramic insulator 122 connected to the electrode holder 17 is placed inside the electrode box 121. The metal end of the electrode holder 17 is connected to the output end of the ceramic insulator 122, and the wire is connected to the ceramic insulator 122 to supply power to the electrode wire 18. The length of the wire can be adapted according to the displacement of the electrode holder 17.

[0040] like Figure 6 As shown, the electrode holder 17 is displaced. Motors 16 are fixed to the outer surfaces of the lower housing 1 and the upper housing 12, respectively. Motors 16 are positioned between two adjacent ceramic insulator columns 122, and a lifting link 162 is fixed below the two columns. A threaded sleeve 163 is fixed at the center above the outer surface of the lifting link 162. Simultaneously, a threaded rod 161 is fixed at the output end below motors 16, with its end extending to the threaded sleeve 163 and forming a threaded connection. Therefore, when both motors 16 operate simultaneously, the threaded rod 161 below the output end of motors 16 causes the threaded sleeve 163 to move up and down together, thereby allowing the electrode holder 17 to move accordingly.

[0041] like Figures 5-6The diagram illustrates the detailed structure of the scraping mechanism according to the first embodiment of this application. The scraping mechanism is located at the center of the electrostatic adsorption tube 11 and moves up and down together with the electrode holder 17. The scraping mechanism in the first embodiment consists of a scraping ring 194 whose outer ring abuts against the inner ring wall of the electrostatic adsorption tube 11. The scraping ring 194 has a certain degree of toughness to prevent damage to the inner ring wall of the electrostatic adsorption tube 11. A connecting ring 192 is sleeved on the outer circumferential surface of the electrode wire 18. A connecting rod 193 connects the connecting ring 192 and the scraping ring 194. Therefore, when the connecting ring 192 moves, the connecting rod 193 can drive the scraping ring 194 to move along with it. Furthermore, the scraping rings 194 are evenly distributed on the inner ring wall of the electrostatic adsorption tube 11, and the adjacent connecting rings 192 are connected by the connecting rod 191, so that multiple scraping rings 194 can move together to scrape the inner ring wall of the electrostatic adsorption tube 11. At the same time, a connecting plate 19 is fixed on the bottom surface of the electrode frame 17, and the bottom surface of the connecting plate 19 is connected to the end of the connecting rod 191. Therefore, when the exhaust gas needs dust removal, the exhaust gas enters the interior of the upper chamber 12 through the air inlet 13, and then is ionized by the electrode wire 18, so that the particles in the exhaust gas can be adsorbed by the electrostatic adsorption tube 11. At the same time, the spray system 15 sprays normally to cool down and clean some impurities. When the inner ring wall of the electrostatic adsorption tube 11 needs to be treated, the motor 16 located on the outer surface of the lower chamber 1 and the upper chamber 12 can be operated. Then the threaded rod 161 below the output end of the motor 16 can make the threaded sleeve 163 move up and down together, and then the electrode frame 17 can move together. During the movement of the electrode frame 17, the scraper ring 194 can continuously scrape the electrostatic adsorption tube 11 through the connecting rod 191. Then, in conjunction with the spray of the spray system 15, the cleaning effect of the electrostatic adsorption tube 11 can be improved.

[0042] like Figures 7-9 The image shows a second embodiment of this application. This embodiment maintains the same design concept as the first embodiment, but modifies the scraping mechanism. In this embodiment, the scraping mechanism consists of a scraper 24 that adheres to the inner annular wall of the electrostatic adsorption tube 11. The scraper 24 extends downward from the opening above the electrostatic adsorption tube 11, and there are multiple scrapers evenly distributed around the center of the electrostatic adsorption tube 11. The multiple scrapers 24 are connected and fixed together by connecting rings 241, thereby enabling the scrapers 24 to form an annular shape to scrape the inner annular wall of the electrostatic adsorption tube 11.

[0043] A rotating ring 23 is sleeved on the outer periphery of the electrode wire 18 located above the electrostatic adsorption tube 11. The lower edge of the rotating ring 23 is connected to the top of the scraper 24 by a connecting rod 221. An inclined guide groove 231 is provided on the outer periphery of the rotating ring 23. A collar 22 is fixed on the outer periphery of the connecting rod 221 and sleeved at the opening of the electrostatic adsorption tube 11. The collar 22 has an open bottom surface and the opening of the collar 22 forms a concave-convex fit with the opening of the electrostatic adsorption tube 11. Therefore, the collar 22 allows the scraper 24 to rotate within the inner ring wall of the electrostatic adsorption tube 11.

[0044] A connecting plate 2 is fixed to the bottom surface of the electrode holder 17, and the center opening of the connecting plate 2 allows the electrode wire 18 to pass through. A push rod 21 extends downward from one side of the bottom surface of the connecting plate 2. The outer surface of the push rod 21 is attached to the rotating ring 23, and a protrusion on one side of the outer surface of the push rod 21 extends to the guide groove 231. Therefore, as the electrode holder 17 moves downward, the push rod 21 below the electrode holder 17 moves downward together. Since the protrusion on one side of the outer surface of the push rod 21 extends to the guide groove 231, the push rod 21 can cause the rotating ring 23 to rotate during the downward movement of the electrode holder 17. When the rotating ring 23 rotates, the scraper 24 can scrape off the adsorbed particles of the electrostatic adsorption tube 11 through the connecting rod 221.

[0045] like Figures 10-11 As shown, a collection tower 4 is fixed to the bottom surface of the lower housing 1. The collection tower 4 has a recessed structure with its bottom facing downwards. A rotating hole 41 is opened downwards on the upper surface of the collection tower 4. A rotatable filter cylinder 42 is located at the center of the rotating hole 41. A collection cylinder 43 is also fixed to the bottom surface of the collection tower 4. The collection cylinder 43 is hollow inside, so that it fits onto the outer circumference of the filter cylinder 42, allowing the filtered solution to be collected inside the collection cylinder 43. The bottom surface of the collection cylinder 43 is open, allowing the bottom surface of the filter cylinder 42 to be placed at the opening.

[0046] A gear ring 421 is fixed to the bottom surface of the filter cylinder 42. This gear ring 421 meshes with a gear 71 on one side of the outer circumference of the collection cylinder 43. Simultaneously, the output end of a motor 7, fixed to the outer circumference of the collection cylinder 43, is connected to the center of the gear 71. Therefore, when the motor 7 rotates, it drives the gear 71 to rotate. A connecting pipe 432 for discharging the internal solution is also fixed to the outer circumference of the collection cylinder 43. Therefore, during dust removal, the spray system 15 inside the upper housing 12 sprays the solution, which is then filtered and collected by the filter cylinder 42. Simultaneously, the motor 7 drives the gear 71 below, which in turn drives the meshing gear ring 421. The rotation of the gear ring 421 accelerates the rotation of the filter cylinder 42, thus accelerating the filtration of the solution.

[0047] like Figures 11-14 As shown, during the filtration process of the filter cartridge 42, particulate impurities will continuously accumulate inside the hollow interior of the filter cartridge 42, thus requiring regular cleaning, which will affect the operation of the dust removal device. A top rod 3 is fixed to the bottom surface of the electrode holder 17 located below the electrostatic adsorption tube 11. The top rod 3 faces the upper opening of the filter cartridge 42, and a connector 31 is fixed to the end of the top rod 3. The connector 31 is in an inverted T-shape, and a rotatable spiral blade 5 is located at the center of the filter cartridge 42. A rotating shaft 51 is connected to the spiral blade 5, so rotating the rotating shaft 51 allows the spiral blade 5 to rotate as well. The connector 31 is positioned on top of the rotating shaft 51, allowing the spiral blade 5 to move along with it via the top rod 3.

[0048] A base plate 6 is also fitted onto the bottom surface of the rotating shaft 51, and a rotating groove 63 is also provided in the base plate 6. At the same time, a magnetic ring 52 is fixed at the end of the rotating shaft 51. Balls are distributed between the top surface of the magnetic ring 52 and the top surface of the rotating groove 63, and multiple magnetic blocks are evenly distributed on the outer circumference of the magnetic ring 52.

[0049] A second magnetic ring 62 is also provided on one side of the first magnetic ring 52. Magnetic blocks that attract the first magnetic ring 52 are also distributed on the outer circumference of the second magnetic ring 62. The rotating shaft extending from the axis of the second magnetic ring 62 is placed in the rotating groove 63, allowing the second magnetic ring 62 to rotate around this shaft. The bottom surface of the filter cartridge 42 is open, and the bottom plate 6 seals the opening to prevent particles inside the filter cartridge 42 from falling out.

[0050] A magnetic ring 3 422 is fixed at the edge of the bottom opening of the filter cylinder 42. The inner ring wall of the magnetic ring 3 422 is in contact with the outer circumference of the base plate 6, and the inner ring wall of the magnetic ring 3 422 is also provided with a magnetic block that is attracted to the magnetic ring 2 62. A guide tube 61 is fixed downward on the bottom surface of the base plate 6, and a guide rod 431 extends from the outer circumference of the collection cylinder 43 towards the guide tube 61. The bottom surface of the guide tube 61 is open and fits onto the outer circumference of the guide rod 431. Therefore, when the dust removal device is running, the motor 7 on the outer periphery of the collection cylinder 43 drives the filter cylinder 42 to rotate, thereby achieving the filtering effect. During the rotation and filtering process of the filter cylinder 42, the magnetic ring 3 422 drives the magnetic ring 2 62 inside the rotating groove 63. Then, the magnetic ring 2 62 drives the magnetic ring 1 52 through magnetic attraction, thereby causing the rotating shaft 51 above the magnetic ring 1 52 to rotate together. As the rotating shaft 51 rotates, the spiral blades 5 continuously push the particulate impurities down to the bottom surface of the filter cylinder 42, so as to facilitate the filtration of the area above the filter cylinder 42. As the electrode frame 17 moves downward, the electrode frame 17 pushes the top rod 3 to move the bottom plate 6 out from the opening of the filter cylinder 42. Then, the particulate impurities inside the filter cylinder 42 fall off, making it convenient to clean the inside of the filter cylinder 42.

[0051] The working principle of an electrostatic exhaust gas dust removal device is as follows: When exhaust gas needs to be treated for dust removal, the exhaust gas enters the interior of the upper chamber 12 through the air inlet 13, and then is ionized by the electrode wire 18, so that the particles in the exhaust gas can be adsorbed by the electrostatic adsorption tube 11. At the same time, the spray system 15 sprays normally to cool down and clean some impurities. When the inner ring wall of the electrostatic adsorption tube 11 needs to be treated, the motor 16 located on the outer surface of the lower chamber 1 and the upper chamber 12 can be operated. Then, the threaded rod 161 below the output end of the motor 16 can make the threaded sleeve 163 move up and down together, and then the electrode frame 17 can move together. During the movement of the electrode frame 17, the inner ring wall of the electrostatic adsorption tube 11 can be scraped by the scraping mechanism. Then, in conjunction with the spraying of the spray system 15, the cleaning effect of the electrostatic adsorption tube 11 can be improved.

[0052] While the scraping mechanism is cleaning, the spray system 15 inside the upper housing 12 sprays the solution, which is then filtered and collected by the filter cartridge 42. At the same time, the motor 7 drives the gear 71 below, which in turn drives the meshing gear ring 421 on one side. After the gear ring 421 rotates, the filter cartridge 42 rotates faster, allowing the solution to be filtered out more quickly. During the filtration process of the filter cartridge 42, the magnetic ring 422 drives the magnetic ring 62 inside the rotating groove 63. Then, the magnetic ring 62 drives the magnetic ring 52 through magnetic attraction, which in turn causes the rotating shaft 51 above the magnetic ring 52 to rotate as well. As the rotating shaft 51 rotates, the spiral blades 5 continuously push the particulate impurities down to the bottom surface of the filter cartridge 42, facilitating filtration of the upper area of ​​the filter cartridge 42. As the electrode frame 17 moves downward, it pushes the top rod 3, which moves the bottom plate 6 out of the opening of the filter cartridge 42. Then, the particulate impurities inside the filter cartridge 42 fall off, making it easier to clean the inside of the filter cartridge 42.

[0053] It should be noted that the specific models and specifications of electrode box 121, motor one 16, electrode frame 17, electrode wire 18 and motor two 7 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0054] The power supply and operating principle of the electrode box 121, motor 16, electrode frame 17, electrode wire 18 and motor 7 are clear to those skilled in the art and will not be described in detail here.

[0055] It is understood that the present invention has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention.
