[0001] This invention relates to the field of flue gas filtration technology, and in particular to a flue gas filtration and dust removal device. Background Technology

[0002] With the acceleration of industrialization, industrial emissions have become one of the main sources of air pollution. These emissions contain a large amount of particulate matter, such as dust and soot, which not only reduce visibility and affect air quality but also pose serious health risks, potentially causing respiratory and cardiovascular diseases. Therefore, efficient filtration and dust removal of flue gas is a crucial task for environmental protection.

[0003] Some existing flue gas filtration and dust removal equipment cleans the filter cartridges by installing air jets on top of the cartridges. However, over time, dust accumulates on the filter cartridges, reducing the effectiveness of the air jet cleaning and thus reducing the cleaning efficiency of the filter cartridges. Furthermore, the reduced filtration efficiency of the filter cartridges after prolonged use necessitates replacement. However, existing flue gas filtration and dust removal equipment makes filter cartridge replacement inconvenient and involves complex procedures. Summary of the Invention

Detailed Implementation

[0016] The following is in conjunction with the appendix Figure 1 —6. The present invention will be described in further detail.

[0017] This invention discloses a flue gas filtration and dust removal device, including a filter box 1, which is fixedly installed on a mounting base 2. A door is provided on the front side of the filter box 1. An air outlet pipe 3 is installed in a through hole opened on the left side of the filter box 1 near the top. A hopper 4 is installed at the bottom of the filter box 1, and a receiving box 5 is provided at the bottom of the hopper 4. A first cleaning mechanism is installed on the top of the filter box 1. A filter mechanism is installed inside the filter box 1 below the first cleaning mechanism. A second cleaning mechanism is installed inside the filter box 1 at the bottom of the filter mechanism. The first cleaning mechanism drives the second cleaning mechanism to move up and down to clean the filter mechanism. An air inlet mechanism is also connected to the right outer wall of the filter box 1.

[0018] refer to Figure 2 and Figure 3The first cleaning mechanism includes an electric telescopic rod 6 installed on the top of the filter box 1. The output end of the electric telescopic rod 6 passes through a through hole in the top of the filter box 1 and is connected to a support plate 7 installed inside the filter box 1. Three sets of symmetrical annular fixing blocks 8 are provided at the bottom of the support plate 7. Three identical air storage pipes 9 are installed between the three sets of annular fixing blocks 8. One end of each air storage pipe 9 is connected to a first connecting hose. The other end of the first connecting hose extends out of the filter box 1 and is connected to one end of a first connecting pipe 10 on the air pump 11. The air pump 11 is fixedly installed on a support base 12 installed on the right side wall of the filter box 1. Several sets of symmetrical jet assembly are also installed on the air storage pipe 9. The jet assembly includes several jet pipes 13 connected to the air storage pipe 9. One end is connected to a rotating nozzle 14, and a cover 15 is also provided on the air jet pipe 13. A top rod 16 is also installed on the bottom side of the support plate 7. More specifically, the electric telescopic rod 6 drives the support plate 7 to move downward, so that the bottom of the support plate 7 moves downward through the air storage pipe 9 installed by the annular fixing block 8, so that the air jet pipe 13 connected to the air storage pipe 9 is inserted into the corresponding filter cartridge 21. The air pump 11 is started, and gas is filled into the air storage pipe 9 through the action of the first connecting pipe 10 and the first connecting hose, and then delivered to the nozzle 14 through the air jet pipe 13. The nozzle 14 blows out the dust on the filter cartridge 21, thereby cleaning the filter cartridge 21. The electric telescopic rod 6 drives the nozzle 14 to move up and down to spray air, so that the filter cartridge 21 is cleaned more thoroughly.

[0019] refer to Figure 4The filtration mechanism includes symmetrical mounting frames 17 installed on the inner walls of both sides of the filter box 1. A movable frame 18 is slidably mounted between the mounting frames 17. The movable frame 18 has movable holes 19. A mounting plate 20 is provided on the front side of the movable frame 18. The mounting plate 20 has several mounting holes, and a corresponding filter cartridge 21 is installed in each mounting hole. A drive assembly is provided inside the mounting frame 17 to move the filter cartridge 21 out of the filter box 1. The drive assembly includes a lead screw 22 installed inside one of the mounting frames 17. One end of the lead screw 22 is connected to a bearing seat provided on the inner wall of one end of the mounting frame 17. The other end of the lead screw 22 passes through a through hole that connects the mounting frame 17 and the side wall of the filter box 1, and is fixedly mounted to the back of the filter box 1. The output end of the drive motor 23 is connected to the lead screw 22, and a lead screw sleeve seat is also fitted on the lead screw 22. One end of the lead screw sleeve seat is connected to one end of the movable frame 18. A slide rod 24 is installed inside the other mounting frame 17. A slider is slidably installed on the slide rod 24. The other end of the slider is connected to the other end of the movable frame 18. More specifically, the operation of the drive motor 23 drives the lead screw 22 connected to the output end to rotate, causing the lead screw sleeve seat to slide along one of the mounting frames 17, and causing the movable frame 18 to slide along the slide rod 24 inside the other mounting frame 17 via the slider set at the other end. This causes the movable frame 18 to move and move the filter cartridge 21 installed on the front mounting plate 20 out of the filter box 1, thus facilitating the replacement of the filter cartridge 21 by the staff.

[0020] refer to Figure 5 The second cleaning mechanism includes two symmetrical guide rods 25 installed at the bottom of the movable frame 18. A movable plate 26 is movably installed between the guide rods 25. Symmetrical springs 27 are connected to the bottom of the movable plate 26. The springs 27 are looped around the outer wall of the guide rods 25, and the other end is connected to a circular fixed block at the bottom of the guide rods 25. Several support rods 28 are connected to one side of the movable plate 26. Several annular cleaning brushes 29 are installed on the support rods 28. Each annular cleaning brush 29 is installed on the outer wall of the corresponding filter cartridge 21. More specifically, when the electric telescopic rod 6 in the first cleaning mechanism drives the support plate 7... When moving downwards, the top rod 16 installed at the bottom of one side of the support plate 7 passes through the movable hole 19 on the movable frame 18 and presses the movable plate 26 on the two guide rods 25 installed at the bottom of the movable frame 18. This causes the movable plate 26 to move downwards along the guide rods 25 and press the spring 27. The downward movement of the movable plate 26 drives the annular cleaning brush 29 installed on one side of the support rod 28 to move downwards along the outer wall of the filter cylinder 21 for cleaning. This achieves the goal of cleaning the outer wall of the filter cylinder 21 first, and then cleaning the inside of the filter cylinder 21 by air jet cleaning from the nozzle 14, making the cleaning effect more thorough and improving the filtration effect.

[0021] refer to Figure 3 and Figure 6The air intake mechanism includes a cyclone separator 30 located on the right side of the filter box 1. The cyclone separator 30 is mounted on a support frame 31 located at the top of one end of the mounting base 2. An inlet pipe 32 is installed on the outer wall of the cyclone separator 30, and a discharge pipe 33 is installed at the bottom of the cyclone separator 30. The other end of the discharge pipe 33 is connected to a receiving box 5 located at the bottom of the filter box 1. A second connecting pipe is connected to the top of the cyclone separator 30. The other end of the second connecting pipe is connected to an exhaust pipe 34 fixedly installed on the right side wall of the filter box 1. Several second connecting hoses are provided on the exhaust pipe 34. The other end of the second connecting hoses passes into the interior of the filter box 1 and is connected to one end of a branch pipe 35. The branch pipes 35 are respectively connected to through holes opened on the outer wall of the cover 15 on the jet pipe 13. A fixing plate 36 is also installed at one end of the branch pipe 35. The bottom of the fixed plate 36 is connected to symmetrical cylinders 37, which are fixedly installed on the top of one of the mounting frames 17. More specifically, the cylinders 37 are first driven to move the fixed plate 36, causing the branch pipe 35 to move downward, so that the hood 15 moves downward and fits against the top of the filter cylinder 21. Then, the flue gas enters the cyclone separator 30 through the smoke inlet pipe 32 for separation. Larger particles in the flue gas will be separated and discharged into the receiving box 5 through the discharge pipe 33. The separated flue gas enters the exhaust pipe 34 through the second connecting pipe, and is then transported to the branch pipe 35 by the second connecting hose installed on the exhaust pipe 34. The branch pipe 35 transports the flue gas into the hood 15, thereby transporting the flue gas into the filter cylinder 21 for filtration. The fit between the hood 15 and the filter cylinder 21 can prevent the flue gas from escaping and improve the filtration effect.

[0022] The implementation principle of a flue gas filtration and dust removal device according to an embodiment of the present invention is as follows: When filtering and removing dust from flue gas, firstly, the cylinder 37 is driven to move the fixed plate 36, causing the branch pipe 35 to move downward, so that the cover 15 moves downward and fits against the top of the filter cylinder 21. Then, the flue gas enters the cyclone separator 30 through the inlet pipe 32 for separation. Larger particles in the flue gas are separated and discharged into the receiving box 5 through the discharge pipe 33. The separated flue gas enters the exhaust pipe 34 through the second connecting pipe, and is then connected by the second connecting pipe installed on the exhaust pipe 34. The connecting hose delivers the flue gas to the branch pipe 35, which then delivers the flue gas to the hood 15, thereby allowing the flue gas to be filtered inside the filter cartridge 21. The filtered flue gas is then discharged through the outlet pipe 3. When cleaning the filter cartridge 21, the electric telescopic rod 6 is driven to move the support plate 7 downwards, causing the gas storage pipe 9 and the top rod 16 installed at the bottom of the support plate 7 to move downwards. The top rod 16 first passes through the movable hole 19 on the movable frame 18 and presses against the movable plate 26, causing the movable plate 26 to move downwards along the guide rod 25 and press against the spring 27. The pressure causes the movable plate 26 to move downwards, which in turn moves the annular cleaning brush 29 mounted on the support rod 28 downwards along the outer wall of the filter cylinder 21 for cleaning. The jet pipe 13 connected to the air storage pipe 9 is then inserted into the corresponding filter cylinder 21. The air pump 11 is activated, and gas is injected into the air storage pipe 9 through the first connecting pipe 10 and the first connecting hose. Air is then sprayed onto the filter cylinder 21 through the nozzle 14 connected to one end of the jet pipe 13. The electric telescopic rod 6 moves the nozzle 14 up and down to spray air, making the filter cylinder 21 cleaner. The system is designed to clean the filter cartridge 21 by first cleaning its outer wall and then by spraying air into the inside of the filter cartridge 21 through the nozzle 14. This process ensures a more thorough cleaning and improves the filtration efficiency. The cleaned dust falls into the receiving box 5 through the bottom hopper 4 of the filter box 1. When the filter cartridge 21 needs to be replaced, the drive motor 23 rotates the lead screw 22, causing the moving frame 18 to move and move the filter cartridge 21 mounted on the front mounting plate 20 out of the filter box 1, making it easier for staff to replace the filter cartridge 21.

[0023] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
