Description

A dust removal device for zinc oxide production kiln flue gas. Technical Field

[0001] This invention belongs to the field of flue gas treatment technology, specifically a dust removal device for flue gas from zinc oxide production kilns. Background Technology

[0002] In the production process of zinc oxide, a kiln is used to melt and evaporate zinc-containing materials. The flue gas produced by the kiln contains harmful substances, and if it is directly emitted, it will pollute the air. Therefore, the flue gas needs to be treated for dust removal so that it meets the emission standards.

[0003] Patent CN216909831U discloses an industrial kiln flue gas desulfurization, denitrification, and dust removal device, comprising: a dust collection box, a fan fixedly connected to one side of the dust collection box, a first filter screen fixedly connected to the dust collection box near the fan, a second filter screen disposed on the side of the first filter screen away from the dust collection box, one side of the second filter screen fixedly connected to the first filter screen, and the other side of the second filter screen fixedly connected to the dust collection box; this patent, by setting up a storage mechanism, enables the dust removal mechanism to improve the desulfurization and denitrification effect of the treatment liquid on the exhaust gas. Traditional industrial kiln flue gas desulfurization, denitrification, and dust removal devices generally discharge the exhaust gas directly into the treatment liquid for treatment, resulting in poor desulfurization and denitrification effects. This industrial kiln flue gas desulfurization, denitrification, and dust removal device can atomize the treatment liquid and spray it evenly into the dust collection box to treat the exhaust gas for desulfurization and denitrification, thereby improving the treatment effect of the exhaust gas.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. The present invention discloses a dust removal device for zinc oxide production kiln flue gas. It utilizes a cleaning component and a brush roller to periodically clean the outer surface of the filter bag, maintaining its cleanliness. This avoids the problem of dust clogging the filter pores, which affects flue gas permeability and subsequent filtration efficiency. After cleaning, the brush roller and baffle are reset. The reset baffle separates the brush roller from the filter bag, preventing dust in the flue gas from adhering to the brush roller surface when it enters the dust collection chamber. This maintains the cleanliness of the brush roller surface to a certain extent, reduces the maintenance frequency, and helps extend the service life of the brush roller.

[0023] 2. The zinc oxide production kiln flue gas dust removal device of the present invention utilizes an extrusion component. When the brush roller cleans the outer surface of the filter bag, the pressure roller squeezes the area of ​​the filter bag being cleaned from the inside of the filter bag, causing the cleaned area to bulge. This reduces the depressions and wrinkles in the compressed area of ​​the filter bag, thereby avoiding the problem that residual dust is difficult to remove completely due to the depressions and wrinkles on the surface of the filter bag when the brush roller cleans the filter bag, thus affecting the cleaning efficiency.

[0024] 3. The zinc oxide production kiln flue gas dust removal device of the present invention utilizes an adjustable support component, which can both drive the support rod away from the filter bag when the pressure roller squeezes the filter bag, so that the filter bag has a large deformation space and avoids damage to the filter bag due to the pressure of the pressure roller, and provide support for the filter bag when the pressure roller is not squeezing the filter bag, so that the filter bag can be fully unfolded and the filtration effect is guaranteed.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please refer to Figures 1-8. The present invention provides a technical solution: a dust removal treatment device for flue gas from a zinc oxide production kiln, including a dust removal box 1, an air inlet 4 provided on one side of the upper end of the dust removal box 1, a connecting pipe 34 connected to one side of the dust removal box 1, a treatment box 3 connected to one end of the connecting pipe 34, a partition 35 fixedly connected to one side of the inner wall of the dust removal box 1, a filter bag 9 fixedly connected to the through hole in the middle of the partition 35, and an adjustable support assembly provided on one side of the inner cavity of the dust removal box 1.

[0037] The adjustable support assembly includes a fixed plate 17 fixedly connected to one side of the bottom of the inner cavity of the dust collector 1. The fixed plate 17 has multiple support rods 16 evenly distributed in the circumferential direction, and the multiple support rods 16 are slidably connected to the fixed plate 17 in the radial direction. The support rods 16 extend axially along the fixed plate 17 to the inner wall of the filter bag 9, and the support rods 16 are in contact with the inner wall of the filter bag 9.

[0038] The inner cavity of the dust collection box 1 is also equipped with a cleaning component;

[0039] The cleaning assembly includes a guide rail plate 26 fixedly connected to one side of the inner wall of the dust collector 1, a slider 10 slidably connected to one side of the guide rail plate 26, a rotating plate 12 rotatably mounted on one side of the slider 10, a brush roller 14 rotatably mounted on one side of the lower end of the rotating plate 12, and a collection box 8 mounted on one side of the bottom of the inner cavity of the dust collector 1.

[0040] In this embodiment, as shown in Figures 1-3 and 5-8, an exhaust pipe 31 is provided on one side of the treatment box 3, a spray pipe 32 is fixedly connected to one side of the inner wall of the treatment box 3, a plurality of nozzles 33 are provided on the spray pipe 32, a water storage tank 2 is fixedly connected to one side of the upper end face of the treatment box 3, a pump body 30 is connected and fixedly connected to one side of the water storage tank 2, and the liquid outlet end of the pump body 30 is connected to one side of the spray pipe 32.

[0041] A guide rail plate 5 is fixedly connected to one side of the upper end of the dust collector 1. A baffle 6 is slidably connected to one side of the guide rail plate 5. The baffle 6 is inserted into and slidably connected to one side of the dust collector 1.

[0042] A threaded rod 27 is threadedly connected to one side of the slider 10. Both ends of the threaded rod 27 are rotatably mounted on the guide rail plate 26. A motor 4 28 is fixedly connected to one side of the outer wall of the dust collector 1. The output end of the motor 4 28 is fixedly connected to one end of the threaded rod 27.

[0043] A motor 11 is fixedly connected to one side of the slider 10. The output end of the motor 11 is fixedly connected to one end of the rotating plate 12. A motor 2 13 is fixedly connected to one end of the rotating plate 12. The output end of the motor 2 13 is fixedly connected to one end of the brush roller 14.

[0044] A threaded rod 7 is threadedly connected to one side of the baffle 6. Both ends of the threaded rod 7 are rotatably mounted on the guide rail plate 5. A motor 29 is fixedly connected to one end of the guide rail plate 5. The output end of the motor 29 is fixedly connected to one end of the threaded rod 7.

[0045] Specifically, in existing technologies, when treating flue gas, filter bags 9 are first used to filter and intercept dust in the flue gas, and then the flue gas is desulfurized and denitrified. However, after a period of use, as dust accumulates on the surface of the filter bags 9, the dust will clog the filter pores, thereby affecting the passage of flue gas and the subsequent filtration effect.

[0046] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0047] The flue gas generated by the kiln during the zinc oxide production process is introduced into the dust collector 1 through the air inlet 4. When the flue gas passes through the filter bag 9, the dust in the flue gas is intercepted on the surface of the filter bag 9. Then, the flue gas enters the treatment box 3 through the connecting pipe 34. Then, the treatment liquid in the water storage tank 2 is extracted by the pump body 30 and sprayed into the treatment box 3 through the spray pipe 32 and the nozzle 33 to perform desulfurization and denitrification treatment on the flue gas. The treated flue gas is discharged through the exhaust pipe 31, thereby realizing the dust removal, desulfurization and denitrification treatment of the flue gas, so that it meets the emission standards and avoids the flue gas from polluting the air.

[0048] After the filter bag 9 has been used for a period of time, the flow of flue gas into the dust collector 1 is stopped. Motor 5 29 drives the threaded rod 7 to rotate, causing the baffle 6 to rise. Then, motor 4 28 drives the threaded rod 27 to rotate, causing the slider 10 to move laterally, aligning the brush roller 14 with the outer surface of the filter bag 9, with the bristles of the brush roller 14 adhering to the outer surface of the filter bag 9. Motor 11 then drives the rotating plate 12 to rotate, causing the brush roller 14 to perform a circular motion. Simultaneously, motor 2 13 drives the brush roller 14 to rotate, so the brush roller 14 rotates on its own axis while revolving around the central axis, cleaning the dust adhering to the outer surface of the filter bag 9. The cleaned dust falls into the collection box 8. This regular cleaning of the outer surface of the filter bag 9 by the brush roller 14 keeps the filter bag 9 clean, preventing dust from clogging the filter pores and affecting the flue gas flow and subsequent filtration effect. After the cleaning work is completed, the brush roller 14 and baffle 6 are reset. The reset baffle 6 separates the brush roller 14 from the filter bag 9. When flue gas enters the dust collector 1, the dust in the flue gas will not adhere to the surface of the brush roller 14, thus maintaining the cleanliness of the brush roller 14 surface to a certain extent, reducing the maintenance frequency of the brush roller 14, and helping to extend its service life. Furthermore, operators can periodically open the chamber door to clean the dust in the collection box 8.

[0049] In this embodiment, as shown in Figures 3 and 4, a pressing component is also provided on the partition 35;

[0050] The extrusion assembly includes a rotating shaft 25 rotatably disposed on one side of the partition 35, a connecting plate 21 fixedly connected to one end of the rotating shaft 25, guide rods 20 slidably connected to both sides of the connecting plate 21, and a pressure roller 18 fixedly connected to one end of the guide rods 20.

[0051] A motor 15 is fixedly connected to one side of the partition 35. The output end of the motor 15 is fixedly connected to one end of the rotating shaft 25. An electric push rod 19 is fixedly connected to one side of the connecting plate 21. The piston end of the electric push rod 19 is fixedly connected to one side of the pressure roller 18.

[0052] Specifically, in the above embodiments, although the filter bag 9 is supported by the support rod 16, as dust adheres to the surface of the filter bag 9 and the flue gas impacts the filter bag 9, the filter bag 9 may develop depressions and wrinkles in some areas. When the brush roller 14 cleans the surface of the filter bag 9, it may be difficult to effectively clean the dust located in the depressions or wrinkles, thus affecting the cleaning effect.

[0053] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0054] When the brush roller 14 cleans along the outer surface of the filter bag 9, the motor 3 15 drives the connecting plate 21 to rotate synchronously. Whenever the pressure roller 18 aligns with the gap between two adjacent support rods 16, the electric push rod 19 drives the pressure roller 18 to squeeze the filter bag 9 in this area, causing a protrusion to form on the outer surface of the filter bag 9. At this time, the brush roller 14 contacts the protruding area on the outer surface of the filter bag 9 and cleans the protruding area. Since the depressions and wrinkles in the area of ​​the filter bag 9 being squeezed are reduced, the dust can be easily swept away. Then the above operation is repeated until the outer surface of the filter bag 9 is evenly cleaned. This avoids the problem that the residual dust is difficult to remove completely due to the depressions and wrinkles on the surface of the filter bag 9 when the brush roller 14 cleans the filter bag 9, thus affecting the cleaning efficiency.

[0055] In this embodiment, as shown in Figure 4, a connecting rod 22 is rotatably provided at one end of the support rod 16, and an adjusting ring 23 is rotatably provided at the other end of the connecting rod 22.

[0056] An electric actuator 24 is fixedly connected to one side of the fixed plate 17, and the piston end of the electric actuator 24 is fixedly connected to one side of the adjusting ring 23.

[0057] Specifically, in the above embodiments, although the pressure roller 18 can squeeze the filter bag 9 to reduce the depressions and wrinkles on the surface of the filter bag 9, since the filter bag 9 is fitted onto and supported by the support rod 16, the pressure between the filter bag 9 and the multiple support rods 16 will increase when one side of the filter bag 9 is squeezed, which may lead to the risk of the filter bag 9 breaking. However, if the gap between the filter bag 9 and the support rod 16 is set too large to avoid this situation, the filter bag 9 may not be able to fully unfold, thus affecting the filtration effect.

[0058] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0059] Whenever the pressure roller 18 squeezes the filter bag 9, the electric actuator 24 drives the adjusting ring 23 to move, which in turn drives the support rod 16 to slide on the fixed plate 17 via the connecting rod 22. This causes multiple support rods 16 to move simultaneously toward the axis of the fixed plate 17, increasing the gap between the support rods 16 and the filter bag 9. At this time, when the pressure roller 18 squeezes the filter bag 9 again, the filter bag 9 has a larger deformation space, thus preventing the filter bag 9 from being damaged by the pressure roller 18. Subsequently, when the pressure roller 18 stops squeezing the filter bag 9, the support rod 16 returns to its original position and provides support for the filter bag 9, allowing the filter bag 9 to fully unfold and ensuring the subsequent filtration effect.

[0060] Working principle: The flue gas generated by the kiln during the zinc oxide production process is introduced into the dust collector 1 through the air inlet 4. When the flue gas passes through the filter bag 9, the dust in the flue gas is intercepted on the surface of the filter bag 9. Then, the flue gas enters the treatment box 3 through the connecting pipe 34. Then, the treatment liquid in the water storage tank 2 is extracted by the pump body 30 and sprayed into the treatment box 3 through the spray pipe 32 and the nozzle 33 to perform desulfurization and denitrification treatment on the flue gas. The treated flue gas is discharged through the exhaust pipe 31, thereby realizing the dust removal, desulfurization and denitrification treatment of the flue gas, so that it meets the emission standards and avoids the flue gas from polluting the air. After the filter bag 9 has been used for a period of time, the flow of flue gas into the dust collector 1 is stopped. Motor 5 29 drives the threaded rod 7 to rotate, causing the baffle 6 to rise. Then, motor 4 28 drives the threaded rod 27 to rotate, causing the slider 10 to move laterally, aligning the brush roller 14 with the outer surface of the filter bag 9, with the bristles of the brush roller 14 adhering to the outer surface of the filter bag 9. Motor 11 then drives the rotating plate 12 to rotate, causing the brush roller 14 to perform a circular motion. Simultaneously, motor 2 13 drives the brush roller 14 to rotate, so the brush roller 14 rotates on its own axis while revolving around the central axis, cleaning the dust adhering to the outer surface of the filter bag 9. The cleaned dust falls into the collection box 8. This regular cleaning of the outer surface of the filter bag 9 by the brush roller 14 keeps the filter bag 9 clean, preventing dust from clogging the filter pores and affecting the flue gas flow and subsequent filtration effect. After the cleaning work is completed, the brush roller 14 and baffle 6 are reset. The reset baffle 6 separates the brush roller 14 from the filter bag 9. When flue gas enters the dust collector 1, the dust in the flue gas will not adhere to the surface of the brush roller 14, thus maintaining the cleanliness of the brush roller 14 surface to a certain extent, reducing the maintenance frequency of the brush roller 14, and helping to extend its service life. Furthermore, operators can periodically open the chamber door to clean the dust in the collection box 8. When the brush roller 14 cleans along the outer surface of the filter bag 9, the motor 3 15 drives the connecting plate 21 to rotate synchronously. Whenever the pressure roller 18 aligns with the gap between two adjacent support rods 16, the electric push rod 19 drives the pressure roller 18 to squeeze the filter bag 9 in this area, causing a protrusion to form on the outer surface of the filter bag 9. At this time, the brush roller 14 contacts the protruding area on the outer surface of the filter bag 9 and cleans the protruding area. Since the depressions and wrinkles in the area of ​​the filter bag 9 being squeezed are reduced, the dust can be easily swept away. Then the above operation is repeated until the outer surface of the filter bag 9 is evenly cleaned. This avoids the problem that the residual dust is difficult to remove completely due to the depressions and wrinkles on the surface of the filter bag 9 when the brush roller 14 cleans the filter bag 9, thus affecting the cleaning efficiency.Whenever the pressure roller 18 squeezes the filter bag 9, the electric actuator 24 drives the adjusting ring 23 to move, which in turn drives the support rod 16 to slide on the fixed plate 17 via the connecting rod 22. This causes multiple support rods 16 to move simultaneously toward the axis of the fixed plate 17, increasing the gap between the support rods 16 and the filter bag 9. At this time, when the pressure roller 18 squeezes the filter bag 9 again, the filter bag 9 has a larger deformation space, thus preventing the filter bag 9 from being damaged by the pressure roller 18. Subsequently, when the pressure roller 18 stops squeezing the filter bag 9, the support rod 16 returns to its original position and provides support for the filter bag 9, allowing the filter bag 9 to fully unfold and ensuring the subsequent filtration effect.
