Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of flue gas treatment, and particularly relates to a zinc oxide production kiln flue gas dust removal treatment device. BACKGROUND

[0002] In the production process of zinc oxide, a kiln is used to melt and evaporate zinc-containing materials, and the flue gas generated by the kiln contains harmful substances. If the flue gas is directly discharged, it will pollute the air. Therefore, the flue gas needs to be treated by dust removal so that the flue gas meets the discharge standard.

[0003] Patent No. CN216909831U discloses an industrial kiln flue gas desulfurization and denitrification dust removal device, which comprises a dust removal box, a fan fixedly connected to one side of the dust removal box, a first filter screen fixedly connected to the side of the dust removal box close to the fan, a second filter screen provided on the side of the first filter screen away from the dust removal box, the first filter screen fixedly connected to one side of the second filter screen, and the other side of the second filter screen fixedly connected to the dust removal box. The patent has the function of improving the desulfurization and denitrification effect of the treatment liquid on the waste gas by setting a storage mechanism. Traditional industrial kiln flue gas desulfurization and denitrification dust removal devices generally directly discharge waste gas into the treatment liquid for treatment, resulting in poor desulfurization and denitrification effect of the waste gas. The industrial kiln flue gas desulfurization and denitrification dust removal device can atomize the treatment liquid and uniformly spray it into the dust removal box to treat the waste gas, thereby improving the treatment effect of the waste gas.

[0004] However, the above technical solution still has the following disadvantages in actual application:

However, after the filter bag is used for a period of time, the dust on the surface of the filter bag increases, which causes the filter holes on the filter bag to be blocked, thereby affecting the passage of the flue gas and the subsequent filtering effect.

The recess and wrinkle of the extruded area of the filter bag are reduced, thereby avoiding the problem that the residual dust is difficult to completely clean due to the recess and wrinkle of the surface of the filter bag when the filter bag is cleaned by the brush roller, thereby affecting the cleaning efficiency.

[0024] 3. The dust removal treatment device for the flue gas of the zinc oxide production kiln disclosed by the present application utilizes the adjustable supporting assembly.

[0039] The cleaning assembly comprises a guide rail plate two 26 fixedly connected to one side of the inner cavity wall of the dust removal box 1, a sliding block 10 slidingly connected to one side of the guide rail plate two 26, a rotating plate 12 rotatably arranged on one side of the sliding block 10, a brush roller 14 rotatably arranged on one side of the lower end of the rotating plate 12, and a collection box 8 arranged on one side of the bottom of the inner cavity of the dust removal box 1.

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

[0041] One side of the upper end face of the dust removal box 1 is fixedly connected with a guide rail plate one 5, one side of the guide rail plate one 5 is slidingly connected with a baffle 6, and the baffle 6 is inserted and slidingly connected with one side of the dust removal box 1.

[0042] One side of the sliding block 10 is threadedly connected with a threaded rod two 27, both ends of the threaded rod two 27 are rotatably arranged on the guide rail plate two 26, one side of the outer wall of the dust removal box 1 is fixedly connected with a motor four 28, and the output end of the motor four 28 is fixedly connected with one end of the threaded rod two 27.

[0043] One side of the sliding block 10 is fixedly connected with a motor one 11, the output end of the motor one 11 is fixedly connected with one end of the rotating plate 12, one end of the rotating plate 12 is fixedly connected with a motor two 13, and the output end of the motor two 13 is fixedly connected with one end of the brush roller 14.

[0044] One side of the baffle 6 is threadedly connected with a threaded rod one 7, both ends of the threaded rod one 7 are rotatably arranged on the guide rail plate one 5, one end of the guide rail plate one 5 is fixedly connected with a motor five 29, and the output end of the motor five 29 is fixedly connected with one end of the threaded rod one 7.

[0045] Specifically, in the prior art, when treating flue gas, the dust in the flue gas is first filtered and intercepted by the filter bag 9, and then the flue gas is treated by desulfurization and denitrification. After the filter bag 9 is used for a period of time, as the dust on the surface increases, the dust will block the filter holes on the filter bag 9, thereby affecting the passage of the flue gas and the subsequent filtering effect.

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

[0047] The flue gas generated by the kiln in the zinc oxide production process is introduced into the dust removal box 1 through the gas inlet 4. When the flue gas passes through the filter bag 9, the dust in the flue gas will be 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 pump body 30 is used to pump the treatment liquid in the water storage tank 2 out, and then sprayed into the inside of the treatment box 3 through the liquid spraying pipe 32 and the spray head 33. The flue gas is treated by desulfurization and denitrification. The treated flue gas is discharged through the exhaust pipe 31. Thus, the dust removal and desulfurization and denitrification treatment of the flue gas are realized, so that the flue gas can meet the discharge standard and avoid air pollution caused by the flue gas.

[0048] When the filter bag 9 is used for a period of time, stop introducing flue gas into the dust removal box 1. The baffle 6 is driven to rise by rotating the threaded rod 7 driven by the motor 5 29. Then the sliding block 10 is driven to move laterally by rotating the threaded rod 2 7 driven by the motor 4 28. The brush roller 14 is aligned with the outer surface of the filter bag 9, and the bristles of the brush roller 14 are attached to the outer surface of the filter bag 9. Then the rotating plate 12 is rotated by the motor 1 11, and the brush roller 14 makes a circular motion. At the same time, the motor 2 13 drives the brush roller 14 to rotate. The brush roller 14 revolves while also rotating, and the dust attached to the outer surface of the filter bag 9 is cleaned. The cleaned dust falls into the collection box 8. Thus, the outer surface of the filter bag 9 is regularly cleaned by the brush roller 14, so that the filter bag 9 can be kept clean. The problem of dust blocking the filter holes, which affects the flue gas passing and the subsequent filtering effect, is avoided. After the cleaning work is completed, the brush roller 14 and the baffle 6 are reset. The reset baffle 6 separates the brush roller 14 from the filter bag 9. When the flue gas is introduced into the dust removal box 1, the dust in the flue gas will not adhere to the surface of the brush roller 14, thereby maintaining the cleanliness of the surface of the brush roller 14 to some extent, reducing the maintenance frequency of the brush roller 14, and improving the service life of the brush roller 14. The operator can regularly open the door to clean the dust in the collection box 8.

[0049] In the embodiment, as shown in Figure 3 and Figure 4 , the partition plate 35 is further provided with an extrusion assembly;

[0050] The extrusion assembly comprises a rotating shaft 25 rotatably arranged on one side of the partition plate 35. One end of the rotating shaft 25 is fixedly connected with a connecting plate 21. The connecting plate 21 is slidably connected with guide rods 20 on both sides. One end of the guide rod 20 is fixedly connected with a pressure roller 18.

[0051] One side of the partition plate 35 is fixedly connected with a motor 3 15. The output end of the motor 3 15 is fixedly connected with one end of the rotating shaft 25. One side of the connecting plate 21 is fixedly connected with an electric push rod 1 19. The piston end of the electric push rod 1 19 is fixedly connected with 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 Figure 4 As shown, a connecting rod 22 is rotatably mounted on one end of the support rod 16, and an adjusting ring 23 is rotatably mounted on 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] When the pressing roller 18 extrudes the filter bag 9, the adjusting ring 23 is driven to move by the electric push rod 24, the support rods 16 are driven to slide on the fixed disc 17 by the connecting rod 22, and the plurality of support rods 16 are simultaneously moved to the center of the fixed disc 17, so that the gap between the support rods 16 and the filter bag 9 is increased. At this time, the pressing roller 18 extrudes the filter bag 9 again, and the filter bag 9 has a larger deformation space, thereby avoiding damage to the filter bag 9 due to extrusion of the pressing roller 18. Subsequently, when the pressing roller 18 no longer extrudes the filter bag 9, the support rods 16 are reset and provide support for the filter bag 9, so that the filter bag 9 is completely unfolded and the subsequent filtering effect is ensured.

[0060] Working principle: the flue gas generated by the kiln in the production process of zinc oxide is introduced into the dust removal box 1 through the inlet 4, when the flue gas passes through the filter bag 9, the dust in the flue gas will be 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 pump body 30 is used to pump the treatment liquid in the water storage tank 2 out, and then sprayed into the treatment box 3 through the liquid injection pipe 32 and the nozzle 33, so as to carry out desulfurization and denitrification treatment on the flue gas, and then the treated flue gas is discharged through the exhaust pipe 31, so as to realize the dust removal and desulfurization and denitrification treatment of the flue gas, so that it can reach the discharge standard, and avoid the pollution of the flue gas to the air. When the filter bag 9 is used for a period of time, stop introducing flue gas into the dust removal box 1, drive the baffle 6 to rise by rotating the threaded rod 7 driven by the motor 5 29, then drive the sliding block 10 to move transversely by rotating the threaded rod 2 7 driven by the motor 4 28, so that the brush roller 14 is aligned with the outer surface of the filter bag 9, and the bristles of the brush roller 14 are attached to the outer surface of the filter bag 9, then rotate the rotating plate 12 driven by the motor 1 11 to make the brush roller 14 do circular motion, at the same time, the motor 2 13 drives the brush roller 14 to rotate, so that the brush roller 14 rotates while revolving, and the dust adhering to the outer surface of the filter bag 9 is cleaned, and the cleaned dust falls into the collection box 8, so that the outer surface of the filter bag 9 is regularly cleaned by the brush roller 14, so that the filter bag 9 can be kept clean. Avoid the problem that the filter hole is blocked by dust, which affects the flue gas passing and the subsequent filtering effect. After the cleaning work is finished, the brush roller 14 and the baffle 6 are reset, the reset baffle 6 separates the brush roller 14 from the filter bag 9, and when the flue gas is introduced into the dust removal box 1, the dust in the flue gas will not adhere to the surface of the brush roller 14, so that the cleanliness of the surface of the brush roller 14 is maintained to a certain extent, the maintenance frequency of the brush roller 14 is reduced, and the service life of the brush roller 14 is improved. And the operator can regularly open the 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 connecting plate 21 rotates synchronously driven by the motor 3 15, and every time the pressure roller 18 is aligned with the gap between the adjacent two supporting rods 16, the electric push rod 1 19 drives the pressure roller 18 to extrude the filter bag 9 in this area, so that the outer surface of the filter bag 9 forms a protrusion, at this time, the brush roller 14 contacts the protruding area of the outer surface of the filter bag 9 and cleans the protruding area. Since the recess and wrinkles of the extruded area of the filter bag 9 are reduced, the dust can be easily cleaned, then the above operation is repeated until the outer surface of the filter bag 9 is evenly cleaned, so as to avoid the problem that the residual dust is difficult to completely remove when the brush roller 14 cleans the filter bag 9 due to the recess and wrinkles on the surface of the filter bag 9, which affects the cleaning efficiency.When the pressing roller 18 extrudes the filter bag 9, the adjusting ring 23 is driven to move by the electric push rod 24, the supporting rods 16 are driven to slide on the fixed disc 17 by the connecting rod 22, and the multiple supporting rods 16 are simultaneously moved to the axis of the fixed disc 17, so that the gap between the supporting rods 16 and the filter bag 9 is enlarged. At this time, the pressing roller 18 extrudes the filter bag 9 again, and the filter bag 9 has a larger deformation space, thereby avoiding damage of the filter bag 9 caused by extrusion of the pressing roller 18. Subsequently, when the pressing roller 18 no longer extrudes the filter bag 9, the supporting rods 16 are reset and provide support for the filter bag 9, so that the filter bag 9 is completely unfolded and the subsequent filtering effect is ensured.
