Description

Technical Field

[0001] The present invention relates to the technical field of dry-process bag dust removal for coal gas, and in particular to a dry-process bag dust collector for coal gas purification system of an SRV furnace. Background Art

[0002] The SRV furnace is a smelting reduction ironmaking device, and its gas purification system is an important component of this device.

[0003] The SRV furnace gas purification system refers to a series of equipment and processes for purifying the gas generated by the SRV furnace. Its main purpose is to remove impurities such as fly ash, tar, naphthalene, ammonia, hydrogen sulfide, etc. in the gas to ensure the smooth progress of subsequent processes and reduce environmental pollution. The dust bag is the heart of the bag dust collector and is generally called a dust bag or dust filter bag. The dust bag is a key part of the operation of the bag dust collector. Usually, the cylindrical filter bag is hung vertically in the dust collector.

[0004] As the filtration process continues, the dust on the outer surface of the bag will gradually accumulate, increasing the filtration resistance. When the resistance reaches a certain level, the bag needs to be cleaned. The cleaning process usually adopts pulse spraying technology, which sprays the bag with compressed air instantly, causing the filter bag to expand and vibrate rapidly, so that the dust attached to the outer surface of the filter bag is separated from the filter bag under the action of inertia and reverse airflow and falls into the ash hopper.

[0005] Pulse jet technology is only applicable to cylindrical bag filters. When the bag filter is bag-shaped, the surface of the filter is relatively soft, which will greatly reduce the cleaning effect of the pulse jet technology. Therefore, a cleaning device that is conducive to bag-shaped bag filters is needed to remove dust from the bags. Summary of the Invention

[0043] The stretching assembly is arranged in the dust removal box 4, and the stretching assembly includes:

[0044] Mounting plate 18, the side of mounting plate 18 is fixedly connected to the inner wall of air intake box 2, a through slot is provided at the center of mounting plate 18, the upper end surface of mounting plate 18 is fixedly connected to the lower end surface of bag filter 9, and the inner wall of bag filter 9 is also fixedly connected to magnet 10.

[0045] The upper end surface of the filter box 3 is fixedly connected to the upper end surface of the filter box 3, and the upper end surface of the filter box 3 is fixedly connected to the upper end surface of the filter box 3. The upper end surface of the filter box 3 is also provided with a through slot, and the slot wall of the slot is rotatably connected to a rotating rod 13. The upper end surface of the filter box 3 is also provided with a motor 12, and the output end of the motor 12 is belt-driven with the surface of the rotating rod 13. The end surface of the rotating rod 13 is also fixedly connected to a cam 14, and the end surface of the cam 14 away from the rotating rod 13 is fixedly connected to a sliding column 20, and the surface of the sliding column 20 is slidably connected to a sliding frame 21, and the outer surface of the lower end of the sliding frame 21 is fixedly connected to a connecting frame 19, and the lower end surface of the connecting frame 19 is fixedly connected to a sliding block 16, and the upper end surface of the sliding block 16 is provided with a through sliding groove 27, and the inner wall of the sliding groove 27 is slidably connected to a limit rod 15, and the lower end surface of the limit rod 15 is fixedly connected to the upper end surface of the filter box 3.

[0046] Mounting frame 17, the outer surface of mounting frame 17 is fixedly connected to the surface of sliding block 16, the inner wall of mounting frame 17 is rotatably connected to connecting rod 17, the surface of connecting rod 17 rotates and penetrates the upper end surface of filter box 3, and the lower end surface of connecting rod 17 is fixedly connected to magnet 2 36.

[0047] In this embodiment, the gas to be filtered is passed into the air inlet pipe 6, and enters the air inlet box 2 through the air inlet pipe 6, and then enters the filter box 3 through the bag filter 9. Next, it is connected to the air outlet pipe 5 through a pipe to extract the gas in the filter box 3. Under long-term use, dust will adhere to the bag filter 9. When the dust needs to be cleaned, the motor 12 is started to drive the rotating rod 13 to rotate. The rotation of the rotating rod 13 further drives the cam 14 to rotate. The rotation of the cam 14 drives the sliding column 20 to slide on the inner wall of the sliding frame 21, and then cooperates with the limiting effect of the limiting rod 15 to drive the sliding block 16 to move up and down, indirectly driving the connecting rod 7 to move up and down, thereby causing the magnet 2 36 to move up and down, further having the following two motion states:

[0048] First, when connecting rod 1 7 moves downward, it will simultaneously drive magnet 2 36 to move downward. As magnet 2 36 moves downward, the distance between magnet 1 10 and connecting rod 1 36 and connecting rod 1 10 will gradually decrease until magnet 2 36 and connecting rod 1 10 attract each other.

[0049] Second: After magnet 2 36 and magnet 1 10 attract each other, connecting rod 1 7 drives magnet 2 36 to move upward, thereby driving magnet 2 36 to move upward, further pulling the bag filter 9 upward, causing the bag filter 9 to move, thereby driving some dust to fall down, and then as magnet 2 36 and magnet 1 10 rise together, until the bag filter 9 is pulled upward to the maximum limit, magnet 1 10 can no longer rise, and the distance between magnet 2 36 and magnet 1 10 will become farther and farther, until the magnetic attraction between magnet 2 36 and magnet 1 10 is lost, at this time, magnet 1 10 under the action of gravity causes the bag filter 9 to fall quickly to its original state, shaking off the dust to complete the dust cleaning.

[0050] The setting of this stretching component is that the magnet 2 36 moves up and down, and attracts the magnet 1 10 on the bag filter 9, thereby driving the bag filter 9 to move, thereby driving some dust to fall down, and when the bag filter 9 is pulled upward to the maximum limit, the distance between the magnet 2 36 and the magnet 1 10 will become farther and farther, until the magnetic attraction between the magnet 2 36 and the magnet 1 10 is lost. At this time, under the action of gravity, the magnet 10 causes the bag filter 9 to fall quickly to its original state, shake off the dust, and thus improve the dust cleaning effect.

[0051] It is worth noting that, in this embodiment, the gas dry bag dust collector further includes a twisting assembly, which is also arranged in the dust removal box 4, and includes:

[0052] A fixed plate 24 is provided, and the side surface of the fixed plate 24 is fixedly connected to the inner wall of the dust removal box 4. The upper end surface of the fixed plate 24 is fixedly connected to a fixed block 1 23. The lower end surface of the fixed block 1 23 is fixedly connected to a limiting rod 25. The surface of the limiting rod 25 is slidably connected to a kit 26. The outer surface of the kit 26 is slidably connected to a straight tooth row 1 22. The tooth surface of the straight tooth row 1 22 is meshed with a gear ring 18. The inner wall of the gear ring 18 is fixedly connected to the outer surface of the connecting rod 1 7. A through slot is also provided on the side of the sliding block 16. The slot wall is slidably connected to the back tooth surface of the straight tooth row 1 22.

[0053] In this embodiment, during the up and down movement of the sliding block 16, the sleeve 26 will be driven to slide on the surface of the limiting rod 25 at the same time. Since the limiting rod 25 is inclined, the straight tooth row 22 will be driven to slide on the groove on the sliding block 16, and then the gear ring 18 will be driven to rotate, thereby causing the connecting rod 17 to rotate, and further the cloth bag filter 9 will be driven to twist through the mutually attracted magnet 2 36 and magnet 10, and the dust will be further cleaned up by the mutual friction of the inner wall of the cloth bag filter 9.

[0054] The setting of this twisting component is to rotate the connecting rod 1 7, and utilize the mutually attracted magnets 2 36 and 10 to drive the bag filter 9 to twist, and utilize the mutual friction of the inner wall of the bag filter 9 to further clean up the dust, thereby further improving the dust cleaning effect of this dry bag dust collector and ensuring that the bag filter 9 can be maintained in a state of good permeability.

[0055] Example 2, based on the above example:

[0056] See also Figure 2 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 8 The gas dry bag dust collector also includes a vibration component, which is arranged in the dust removal box 4 and includes:

[0057] Rotating disk 1 34, the lower end surface of rotating disk 1 34 is slidably connected to the upper end surface of connecting rod 1 7, the upper end surface of rotating disk 1 34 is provided with a spherical groove, the groove wall of the spherical groove is rotatably connected to the end spherical curved rod 35, the outer surface of mounting frame 17 is fixedly connected to connecting plate 1 33, the surface of connecting plate 1 33 is slidably connected to limit rod 3 32, the upper end surface of limit rod 32 is fixedly connected to baffle 1 28, and the upper end surface of baffle 1 28 is fixedly connected to vibration motor 29.

[0058] Sliding plate 1 31, the lower end surface of sliding plate 1 31 is provided with a spherical groove 2, the groove wall of spherical groove 2 is rotatably connected to the upper spherical surface of the end spherical curved rod 35, the upper end surface of sliding plate 1 31 is also provided with a through groove, the groove wall of the groove is slidably connected to the surface of limit rod 32, the upper end surface of limit rod 32 is fixedly connected with a motion sensor 30, and the motion sensor 30 is used to detect the displacement distance of sliding plate 1 31 relative to baffle 1 28.

[0059] In this embodiment, the rotation of the connecting rod 7 drives the rotating disk 34 to rotate, and the rotation of the rotating disk 34 drives the end spherical curved rod 35 to revolve around the connecting rod 7 as the axis, thereby driving the sliding plate 31 to slide up and down on the surface of the limit rod 32, so that the sliding plate 31 and the baffle 28 have a relative displacement, and then the displacement between the baffles 28 is detected by the mobile sensor 30. For example, when the distance between the sliding plate 31 and the baffle 28 is set to be greater than 10 cm, the vibration motor 29 vibrates, driving the connecting rod 7 to vibrate, thereby driving the bag filter 9 to vibrate. When the distance between the sliding plate 31 and the baffle 28 is less than 10 cm, the vibration motor 29 stops vibrating, so that the vibration of the bag filter 9 is more irregular, the vibration effect is better, and the dust can be better dropped.

[0060] The setting of this vibration component, through the setting of the indirect start-stop vibration motor 29, makes the vibration of the bag filter 9 more irregular, the vibration effect is better, and the dust can be better dropped, further improving the cleaning effect of this dry bag dust collector.

[0061] Example 3, based on the above example:

[0062] See also Figure 1 、 Figure 2 and Figure 3 The gas dry bag dust collector also includes a collection component, which is arranged in the air inlet box 2 and includes:

[0063] The inner walls of the dust outlet pipe 1 and the air inlet box 2 are also provided with a through slot, the slot wall is fixedly connected to the outer surface of the dust outlet pipe 1, and the upper end face of the dust outlet pipe 1 is fixedly connected with a funnel 37, the open end of the funnel 37 is facing the lower end of the bag filter 9.

[0064] In this embodiment, the fallen dust will leak into the funnel 37 and then be discharged into the dry bag dust collector through the dust outlet pipe 1, thereby reducing the accumulation rate of dust inside the dry bag dust collector and improving the ability of the dry bag dust collector to continue working.

[0065] Working principle: When using the gas dry bag dust collector for the SRV furnace gas purification system, the following steps are included:

[0066] S1: The gas to be filtered is passed into the air inlet pipe 6, and then enters the air inlet box 2 through the air inlet pipe 6, and then enters the filter box 3 through the bag filter 9. Next, it is connected to the air outlet pipe 5 through a pipe to extract the gas in the filter box 3;

[0067] S2: When the filter is used for a long time, dust will adhere to the bag filter 9. When the dust needs to be cleaned, the motor 12 is started to drive the magnet 2 36 to move downward until the magnet 2 36 and the magnet 1 10 attract each other.

[0068] S3: After the magnet 2 36 and the magnet 1 10 attract each other, the connecting rod 1 7 rotates, driving the bag filter 9 to twist, and the dust is further removed by the mutual friction of the inner wall of the bag filter 9;

[0069] S4: At the same time, the connecting rod 1 7 drives the second magnet 36 to move upward, pulling the bag filter 9 upward, thereby driving some dust to fall down, until the bag filter 9 is pulled upward to the maximum, and the first magnet 10 cannot rise anymore. The distance between the second magnet 36 and the first magnet 10 will become farther and farther, until the magnetic attraction between the second magnet 36 and the first magnet 10 is lost, so that the bag filter 9 will quickly fall back to its original shape under the action of gravity, shaking off the dust;

[0070] S5: The connecting rod 7 rotates, so that there is a relative displacement between the sliding plate 31 and the baffle 28. The displacement between the baffles 28 is detected by the mobile sensor 30 to control the start and stop of the vibration motor 29, so that the bag filter 9 vibrates. Finally, the fallen dust will leak into the funnel 37 and then be discharged into the dry bag dust collector through the dust outlet pipe 1, thus completing the use of the dry bag dust collector.
