Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, specifically to a waste gas odor adsorption and purification device with a pre-filter layer. Background Technology

[0002] In the field of waste gas treatment, activated carbon adsorption technology is widely used in the purification of various industrial waste gases due to its advantages such as high efficiency, reliability and relatively low cost. Activated carbon has a rich pore structure and a large specific surface area, which can effectively remove harmful substances in waste gases, such as volatile organic compounds and odorous gases, through physical adsorption and chemical adsorption. However, as the adsorption process continues, the activated carbon will gradually reach saturation and its adsorption capacity will decrease. At this time, it is necessary to replace the activated carbon in time to ensure the normal operation and treatment effect of the waste gas treatment system.

[0003] However, in the design of existing waste gas odor adsorption and purification devices, the replacement of activated carbon often faces many difficulties. On the one hand, activated carbon is usually installed in the adsorption box in a fixed filling manner, which is a cumbersome process that requires a lot of manpower and time. On the other hand, due to the limited space inside the adsorption box and the tight filling of activated carbon, it is difficult to completely remove the saturated activated carbon during replacement. At the same time, it is also difficult to ensure that the filling of new activated carbon is uniform and dense. This not only affects the replacement efficiency, but may also lead to unstable adsorption effect, increasing the operating cost and maintenance difficulty of the waste gas treatment system. To this end, we propose a waste gas odor adsorption and purification device with a pre-filter layer. Summary of the Invention

[0004] One of the technical problems this application aims to solve is the difficulty in replacing the activated carbon used for adsorption inside the activated carbon adsorption box, which affects its use.

[0005] To address the aforementioned technical problems, this application provides an exhaust gas odor adsorption and purification device with a pre-filter layer, comprising an operation box, an adsorption assembly disposed inside the operation box, the adsorption assembly including a central shaft, a drive assembly disposed at the lower end of the operation box, the central shaft being movably connected to the inner middle of the operation box, centrifugal impellers being fixedly connected to both ends of the central shaft, and a limiting plate being fixedly connected to the outer side of the central shaft, wherein five sets of limiting plates are provided, with two limiting plates in each set, and a placement frame disposed between the two limiting plates in the same set, a sleeve plate being fixedly connected to one side surface of the placement frame, and an activated carbon bag being disposed on the outer side of the sleeve plate.

[0006] In some embodiments, a pressure ring is fixedly connected to one end of the activated carbon bag. One side surface of the pressure ring is in contact with one side surface of the placement rack. Fixing holes are provided on both the pressure ring and the placement rack. The fixing holes on the side of the pressure ring and the fixing holes on the side of the placement rack correspond to each other. An annular pressure plate is provided at the upper end of the pressure ring. A fixing post is fixedly connected to one side surface of the annular pressure plate. The fixing holes and the fixing posts are mutually adapted.

[0007] In some embodiments, a movable cover plate is movably connected to one side of the upper end of the placement rack, and a limiting ring is fixedly connected to one side surface of the movable cover plate. One side surface of the limiting ring is adapted to the upper end of the activated carbon bag, and a fan-shaped block is fixedly connected to one end of the movable cover plate.

[0008] In some embodiments, a traction plate is movably connected to one side surface of the placement rack, an arc-shaped plate is provided on one side of the traction plate, an arc-shaped locking block is fixedly connected to one side surface of the arc-shaped plate, and a guide ring is fixedly connected to the other side of the arc-shaped plate. Two guide rings are provided and are symmetrically distributed. One end of the traction plate is movably connected to the inner side of the two guide rings.

[0009] In some embodiments, a traction door is provided on one side of the arc-shaped plate, a traction handle is fixedly connected to one outer end of the traction door, one end of the traction door is movably connected to the outside of the operation box, an inner groove is provided on the inner surface of the traction door, the inner groove is adapted to the arc-shaped plate, a movable groove is provided on one side surface of the traction door, the inner groove and the movable groove are interconnected, and the movable groove is adapted to the arc-shaped locking block.

[0010] In some embodiments, the drive assembly includes a motor disposed at the lower end of the control box, a drive gear is disposed on one side of the output end of the motor, a linkage rack is movably connected to the outer side of the drive gear, and a protective plate is fixedly connected to the lower end of the control box, the protective plate being disposed on the outer side of the linkage rack.

[0011] In some embodiments, two operation boxes are provided, and a connecting beam is provided between the two operation boxes. Both ends of the connecting beam are fixedly connected to the outside of the operation box. An air guide pipe is fixedly connected to the upper end of the operation box. The inner side of the air guide pipe is connected to the inner side of the operation box. A connecting pipe is provided at the lower end between the two operation boxes, and the connecting pipe connects to the interior of the two operation boxes.

[0012] The present invention has at least the following beneficial effects:

[0013] 1. This invention uses a traction handle to pull the traction door, which is connected to the movable groove and the arc-shaped locking block by a buckle. This causes the arc-shaped plate to move, and then the traction plate drives the placement rack and related components to rotate so that the upper end faces the opening of the traction door. This makes the replacement position of the activated carbon bag clearly visible and provides ample operating space. When installing the activated carbon bag, after the activated carbon bag is placed on the outside of the cover plate, the pressure ring is placed on the outside of the activated carbon bag and moved down to the bottom. During the movement, the activated carbon bag can be shaped to make it flat and stable. The fixed holes and fixed columns are used to stabilize the annular pressure plate and pressure ring to prevent the activated carbon bag from falling off. When the movable cover plate closes, it can effectively fit the upper end of the activated carbon bag. The fan-shaped block stabilizes the closing operation, further ensuring the stable placement of the activated carbon bag. The overall replacement and installation process is simple and efficient.

[0014] 2. This invention utilizes centrifugal impellers symmetrically distributed at both ends of a central shaft within the operating box. As the central shaft drives the impellers to rotate, the waste gas input into the operating box is guided to the inner center of the operating box and the adsorption components, providing favorable conditions for adsorption operation. Multiple adsorption components are arranged on the outer side of the shaft; rotation simultaneously drives multiple adsorption components to rotate, increasing the contact area and contact time between the activated carbon and the waste gas, thus improving adsorption efficiency. Furthermore, the adsorption box employs a series connection of two operating boxes. Waste gas enters through a guide pipe at the top of one operating box, undergoes adsorption within the first operating box, and is then guided to the second operating box through a connecting pipe. This dual adsorption treatment more thoroughly removes harmful substances from the waste gas, ensuring that the waste gas meets emission standards. The overall adsorption operation is highly efficient and reliable. Attached Figure Description

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.

[0025] Example

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8This invention provides a technical solution: a waste gas odor adsorption and purification device with a pre-filter layer, including an operation box 1. An adsorption assembly 2 is disposed inside the operation box 1. The adsorption assembly 2 includes a central shaft 3. A drive assembly 4 is disposed at the lower end of the operation box 1. The central shaft 3 is movably connected to the middle of the inner side of the operation box 1. Centrifugal impellers 11 are fixedly connected to both ends of the central shaft 3. The two centrifugal impellers 11 are symmetrically distributed. When the central shaft 3 drives the centrifugal impellers 11 to rotate, the centrifugal impellers 11 at both ends of the shaft 3 can guide the waste gas input into the operation box 1 to the middle of the inner side of the operation box 1 and the overall position of the adsorption assembly 2, effectively facilitating the adsorption assembly. 2. In overall use, the outer side of the central shaft 3 is fixedly connected to a limiting plate 12. There are five sets of limiting plates 12, with two limiting plates 12 in each set. A placement rack 13 is set between the two limiting plates 12 in the same set. A sleeve plate 14 is fixedly connected to one side surface of the placement rack 13. An activated carbon bag 15 is set on the outer side of the sleeve plate 14. The activated carbon bag 15 is put on the outer side of the sleeve plate 14 from top to bottom. The lower end of the placement rack 13 is movably connected to the outer side of the central shaft 3. When the central shaft 3 rotates, it can drive multiple sets of adsorption components 2 to rotate at the same time. During the overall use, the limiting plate 12 plays a role in limiting and stabilizing the placement rack 13 and related components.

[0027] A pressure ring 16 is fixedly connected to one end of the activated carbon bag 15. One side surface of the pressure ring 16 is in contact with one side surface of the placement rack 13. Fixing holes 17 are provided on both the pressure ring 16 and the placement rack 13. The fixing holes 17 on the pressure ring 16 and the fixing holes 17 on the placement rack 13 correspond to each other. An annular pressure plate 18 is provided at the upper end of the pressure ring 16. A fixing post 19 is fixedly connected to one side surface of the annular pressure plate 18. The fixing holes 17 and the fixing post 19 are mutually compatible. The activated carbon bag 15 is then placed... After the bag 15 is placed on the outside of the sleeve plate 14, the pressure ring 16 is placed on the outside of the activated carbon bag 15. Then, it is moved from top to bottom to the bottom. During the movement, the activated carbon bag 15 can be shaped to make it flatter and more stable. At the same time, the fixing hole 17 and the fixing post 19 are used to make the fixing post 19 snap into the fixing hole 17 when the annular pressure plate 18 moves down, thereby stabilizing the placement of the annular pressure plate 18 and fixing the pressure ring 16 to prevent the activated carbon bag 15 from falling off.

[0028] A movable cover plate 20 is movably connected to one side of the upper end of the placement rack 13. A limiting ring 21 is fixedly connected to one side surface of the movable cover plate 20. One side surface of the limiting ring 21 is adapted to the upper end of the activated carbon bag 15. A fan-shaped block 22 is fixedly connected to one end of the movable cover plate 20. The inner side of the limiting ring 21 is adapted to the upper end of the activated carbon bag 15. When the movable cover plate 20 is closed, it can effectively fit the upper end of the activated carbon bag 15, thereby stabilizing the placement of the activated carbon bag 15. By using the cooperation between the fan-shaped block 22 and one end of the placement rack 13, the movable cover plate 20 can be stably closed by the fan-shaped block 22.

[0029] A traction plate 23 is movably connected to one side surface of the placement rack 13. An arc-shaped plate 24 is provided on one side of the traction plate 23. An arc-shaped locking block 25 is fixedly connected to one side surface of the arc-shaped plate 24. A guide ring 26 is fixedly connected to the other side of the arc-shaped plate 24. Two guide rings 26 are provided and are symmetrically distributed. One end of the traction plate 23 is movably connected to the inner side of the two guide rings 26.

[0030] A traction door 27 is provided on one side of the arc-shaped plate 24. A traction handle 28 is fixedly connected to one outer end of the traction door 27. One end of the traction door 27 is movably connected to the outside of the operation box 1. An inner groove 29 is provided on the inner surface of the traction door 27. The inner groove 29 is adapted to the arc-shaped plate 24. A movable groove 30 is provided on one side surface of the traction door 27. The inner groove 29 and the movable groove 30 are interconnected. The movable groove 30 is adapted to the arc-shaped locking block 25. While the central shaft 3 drives the multiple sets of placement racks 13 to rotate, the traction plate 23 and the guide... The use of the ring 26 causes the arc plate 24 to slide inside the inner groove 29 and the arc-shaped locking block 25 to slide inside the movable groove 30. When the traction handle 28 is used to pull the traction door 27, the locking connection between the movable groove 30 and the arc-shaped locking block 25 causes the arc plate 24 to move synchronously. While the arc plate 24 is moving, the connection of the traction plate 23 can drive the placement rack 13 and related components to rotate to a certain extent, so that its upper end rotates to face the opening of the traction door 27, which facilitates the replacement of the activated carbon bag 15.

[0031] The drive assembly 4 includes a motor 5, which is located at the lower end of the control box 1. A drive gear 6 is provided on one side of the output end of the motor 5. A linkage rack 7 is movably connected to the outside of the drive gear 6. A protective plate 8 is fixedly connected to the lower end of the control box 1. The protective plate 8 is located on the outside of the linkage rack 7. The motor 5 is electrically connected to an external controller, which controls the working state of the motor 5. When the motor 5 is working, its output end drives the drive gear 6 to rotate. At the same time, the linkage rack 7 drives the drive gear 6 at the lower end of the other control box 1 to rotate synchronously. The whole assembly drives the rotation of the central shaft 3 inside the two control boxes 1. While the central shaft 3 is rotating, the two centrifugal impellers 11 lead the waste gas to the adsorption treatment area. Then, the central shaft 3 drives the placement rack 13 connected to the outside to rotate, which facilitates the adsorption treatment of the waste gas by the activated carbon bag 15.

[0032] There are two operating boxes 1, and a connecting beam 9 is provided between the two operating boxes 1. Both ends of the connecting beam 9 are fixedly connected to the outside of the operating box 1. Multiple sets of connecting beams 9 are used to stabilize the fixation and connection between the two operating boxes 1. A gas guide pipe 10 is fixedly connected to the upper end of the operating box 1. The inner side of the gas guide pipe 10 is connected to the inner side of the operating box 1. A connecting pipe 31 is provided at the lower end between the two operating boxes 1. The connecting pipe 31 connects the inside of the two operating boxes 1. When in use, the exhaust gas enters the inside of the operating box 1 from the gas guide pipe 10 at the upper end of one operating box 1. After adsorption operation inside the first operating box 1, it is guided to the inside of the second operating box 1 through the connecting pipe 31. After double adsorption treatment, it is discharged from the inside of the gas guide pipe 10 fixedly connected to the upper end of the other operating box 1.

[0033] When the entire device is in use, the external controller starts the motor 5. The output of the motor 5 drives the drive gear 6 to rotate, which in turn drives the drive gear 6 at the lower end of the two operating boxes 1 to rotate synchronously through the linkage rack 7. This, in turn, drives the central shaft 3 inside the two operating boxes 1 to rotate. The centrifugal impellers 11 at both ends of the central shaft 3 rotate accordingly, guiding the waste gas input from the air guide pipe 10 into the operating box 1 to the middle of the inner side of the operating box 1 and the location of the adsorption component 2. At the same time, the central shaft 3 drives the multiple sets of placement racks 13 fixed by the limiting plate 12 to rotate. The activated carbon bags 15 on the placement racks 13 adsorb the waste gas, achieving pre-filtration. After pre-filtration, the waste gas enters another operating box 1 through the connecting pipe 31 for double adsorption, and finally exits from another air guide pipe 10. Through double adsorption treatment, the waste gas can be removed more thoroughly. Harmful substances are eliminated, ensuring that the exhaust gas meets emission standards. The overall adsorption operation is efficient and reliable. When it is necessary to replace the activated carbon bag 15, pull the traction handle 28 on the traction door 27. The movable groove 30 is connected to the arc-shaped locking block 25 by the buckle, which drives the arc plate 24 to slide in the inner groove 29. Then, the traction plate 23 rotates the placement rack 13 to face the opening of the traction door 27, so that the activated carbon bag 15 can be easily replaced. When installing the activated carbon bag 15, first put it on the outside of the cover plate 14, then put it on the pressure ring 16 and move it down to shape it. Then, use the fixing post 19 of the ring pressure plate 18 to lock into the fixing hole 17. Fix the pressure ring 16 to prevent it from falling off. The movable cover plate 20 is closed, and the limiting ring 21 fits the upper end of the activated carbon bag 15 to further stabilize its placement and ensure the stable placement of the activated carbon bag 15. The overall replacement and installation process is simple and efficient.
