Description

An activated carbon adsorption device for oil removal from gas Technical Field

[0001] This invention relates to the field of activated carbon separation equipment technology, specifically to an activated carbon adsorption device for oil removal from gas. Background Technology

[0002] With the rapid advancement of industrialization and the continuous improvement of environmental protection requirements, the amount of oily fumes and harmful air pollutants generated during various industrial production processes is constantly increasing. These pollutants not only cause extremely serious damage to the environment but also pose a significant threat to human health. Activated carbon, with its highly developed pore structure and large specific surface area, can efficiently adsorb various oily fumes and odorous substances.

[0003] Because oil has strong adhesion, after activated carbon adsorbs oil from the gas, an oil film will appear on the side of the activated carbon facing the air inlet. The presence of the oil film will block the pore structure of the activated carbon, making it difficult for gas to enter the pores and ultimately affecting the filtration efficiency of the activated carbon. To address the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an activated carbon adsorption device for gas oil removal, comprising: a ventilation pipe, a fixed square tube fixedly connected to the inner wall of the ventilation pipe, and an activated carbon plate snapped onto the inner wall of the fixed square tube; a pressure-bearing mechanism slidably connected to the inner wall of the ventilation pipe; a purification mechanism slidably connected to the inner wall of the pressure-bearing mechanism; and a support mechanism fixedly connected to the side wall of the purification mechanism. Before use, the ventilation pipe is fixedly connected to the exhaust port, ensuring that the gas entering the ventilation pipe passes through the fixed square tube and the activated carbon plate before being discharged from the other end.

[0005] Preferably, the pressure-bearing mechanism includes: an auxiliary component that is slidably connected to the inner wall of the ventilation duct; and a limiting component that is fixedly connected to the inner wall of the ventilation duct; wherein, as the activated carbon plate blocks the filter surface due to grease, the air pressure inside the ventilation duct will slowly increase, forcing the auxiliary component to deform.

[0006] Preferably, the impurity removal mechanism includes: a sliding component, which is slidably connected to the inner wall of the auxiliary component; and a grinding component, which is fixedly connected to the side wall of the sliding component; wherein, when the auxiliary component deforms, it will drive the sliding component and the grinding component to slide downward synchronously.

[0007] Preferably, the support mechanism includes: an adaptation component, which is fixedly connected to the bottom of the polishing component; and a limiting component, which is fixedly connected to the side wall of the sliding component. When the sliding component slides downward, the limiting component rotates due to the restriction of the limiting component, and the rotation pressure is transmitted to the adaptation component and the polishing component, so that the polishing component polishes the outer wall of the activated carbon plate.

[0008] Preferably, the auxiliary component includes a sliding plug slidably connected to the inner wall of the bottom through hole of the ventilation pipe, a spring fixedly connected to the outer wall of the sliding plug, a limit rod fixedly connected to the inner wall of the ventilation pipe, a fixing plate fixedly connected to the outer wall of the fixing square tube, and a sealing ring provided at the sliding position of the ventilation pipe and the sliding plug; wherein, under normal conditions, the spring is in an extended state and drives the sliding plug to the highest position. When the air pressure is too high, the air pressure will force the sliding plug to slide downward and compress the spring to accumulate potential energy.

[0009] Preferably, the limiting component includes a slide bar fixedly connected to the inner wall of the ventilation duct, a sliding toothed rod slidably connected to the outer wall of the slide bar, and a second spring fixedly connected to the bottom of the sliding toothed rod; wherein, under normal conditions, the second spring is in an extended state, forcing the top of the sliding toothed rod to be in contact with the top of the inner wall of the ventilation duct.

[0010] Preferably, the sliding assembly includes a sliding plate slidably connected to the inner wall of the sliding plug, and a spring plate is fixedly connected to the bottom of the sliding plate; wherein, under normal conditions, the spring plate will drive the sliding plate to the bottom position of the sliding plug, and when the fixed plate is restricted and the sliding plug continues to move downward, the sliding plug will slide downward along the outer wall of the sliding plate, and the spring plate will be stretched and accumulate potential energy.

[0011] Preferably, the polishing assembly includes a spring telescopic rod fixedly connected to the side wall of the sliding plate, a fixing frame fixedly connected to the end of the spring telescopic rod away from the sliding plate, and a polishing column rotatably connected to the inner wall of the through hole of the fixing frame; wherein, the spring telescopic rod has a push spring inside, and under normal conditions, pushing the spring will drive the fixing frame and the polishing column to be tightly attached to the outer wall of the activated carbon plate.

[0012] Preferably, the adapting component includes a spring retraction rod two fixedly connected to the bottom of the fixing frame one, a rotating rod rotatably connected to the inner wall of the through hole of the spring retraction rod two, and a belt sleeved on the outer wall of the rotating rod; wherein, a push spring two is provided inside the spring retraction rod two, the push spring two will force the spring retraction rod two to extend, and the push force of the push spring one is greater than the push force of the push spring two.

[0013] Preferably, the limiting component includes a fixed frame two fixedly connected to the side wall of the sliding plate, a rotating wheel rotatably connected to the inner wall of the fixed frame two, a rotating disk fixedly connected to the side wall of the rotating wheel, a rotating ring rotatably connected to the side wall of the rotating wheel, a spring plate two fixedly connected to the outer wall of the rotating disk, and an inclined block fixedly connected to the inner wall of the rotating ring. When the sliding component drives the rotating wheel to slide downwards, the rotating wheel, restricted by the sliding toothed rod, will rotate counterclockwise. The counterclockwise rotating wheel drives the rotating disk and the spring plate two to rotate. At this time, the spring plate two will contact the inclined surface of the inclined block. Ultimately, due to the elasticity of the spring plate two, the rotating disk cannot drive the rotating ring to rotate. When the sliding plug slides upwards, the rotating wheel rotates clockwise. The clockwise rotating disk will drive the rotating ring to rotate clockwise through the spring plate two and the inclined block. The rotating ring drives the grinding column to rotate in the same direction via a belt.

[0014] The present invention has the following beneficial effects: (1) The present invention addresses the problem of oil in the gas clogging the activated carbon plate. It is equipped with a pressure-bearing mechanism and a cleaning mechanism inside the device. When the sliding plug slides upward, the rotating wheel rotates clockwise. The clockwise rotating disk will drive the rotating ring to rotate clockwise through the spring plate and the inclined block. The rotating ring drives the grinding column to rotate in the same direction through the belt. Through the application of the above components, when the activated carbon plate is clogged, the grinding column will grind the outer wall of the activated carbon plate, grinding the outermost layer of the activated carbon plate, preventing the oil film from clogging and affecting the filtration efficiency, and extending the service life of the activated carbon plate; (2) The present invention utilizes the downward sliding feature of the sliding plate. A groove is opened on the inner wall of the ventilation pipe, and the outer wall of the sliding plate will slide along the inner wall of the ventilation pipe, as shown in Figure 2. The lowest point U of the groove is higher than the lowest point J of the sliding tooth rod. Therefore, when the sliding plug drives the sliding plate to slide downward, The sliding plate's outer wall is restricted by position U, preventing it from sliding downwards. Meanwhile, the air pressure inside the ventilation duct continues to increase, forcing the sliding plug to press against position J of the sliding toothed rod via the fixed plate. This forces the sliding toothed rod to slide downwards a short distance. As it slides downwards, it drives the rotating wheel to rotate clockwise once. Due to the significant diameter difference between the rotating ring and the receiving end of the grinding column, the grinding column rotates rapidly. This rotating grinding column performs the initial grinding on the outer wall of the activated carbon plate. After the initial grinding, the oil film on the activated carbon plate surface is damaged, allowing gas to pass through again, causing the air pressure to drop. The spring releases its potential energy, slowly driving the sliding plug to slide upwards and reset, completing the grinding process. Grinding the bottom of the activated carbon plate first allows for the automatic pressure release process after high pressure accumulates inside the ventilation duct, preventing excessive pressure from causing cracks in the activated carbon plate.

[0015] (3) The present invention sets the rotating wheel to rotate clockwise to drive the grinding column to rotate, but counterclockwise it cannot drive the grinding column to rotate. This means that the outer wall of the activated carbon plate can only be ground once after the sliding plug has completely moved down under sufficient pressure. It will not cause the auxiliary component to deform due to the pressure inside the ventilation pipe, and the grinding column will grind the outer wall of the activated carbon plate, causing the air pressure to drop, the auxiliary component to reset, and the original grinding position to be blocked again. The auxiliary component will deform and continue to grind the same position, resulting in the phenomenon of repeated grinding of the same position of the activated carbon plate. Through the application of the above components, it is ensured that the contact surface of the activated carbon plate will not change too much after each grinding, and that the activated carbon plate will not crack due to uneven grinding when it is subjected to air pressure.

[0016] (4) In view of the problem that the thickness of the activated carbon plate will decrease after the equipment completes a single grinding, the present invention provides an adaptation component and a grinding component inside the equipment. Since the pushing spring 1 inside the spring telescopic rod 1 has a greater pushing force than the pushing spring 2 inside the spring retraction rod 2, the spring telescopic rod 1 can drive the grinding column to stick tightly to the outer wall of the activated carbon plate after each grinding. In addition, when the spring telescopic rod 1 extends, the spring retraction rod 2 will retract, and the belt will change its adaptability. Through the application of the above components, the grinding column can always stick tightly to the outer wall of the activated carbon plate during use. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] Example 1, please refer to Figures 1-6. This invention is an activated carbon adsorption device for gas oil removal, including a ventilation pipe 13, a fixed square tube 14 fixedly connected to the inner wall of the ventilation pipe 13, and an activated carbon plate 15 snapped onto the inner wall of the fixed square tube 14. It also includes: a pressure receiving mechanism 1, which is slidably connected to the inner wall of the ventilation pipe 13; a dirt removal mechanism 2, which is slidably connected to the inner wall of the pressure receiving mechanism 1; and a support mechanism 3, which is fixedly connected to the side wall of the dirt removal mechanism 2. Before use, the ventilation pipe 13 is fixedly connected to the exhaust port, and it is ensured that the gas entering the ventilation pipe 13 passes through the fixed square tube 14 and the activated carbon plate 15 and is discharged from the other end.

[0022] The pressure-bearing mechanism 1 includes: an auxiliary component 11, which is slidably connected to the inner wall of the ventilation duct 13; and a limiting component 12, which is fixedly connected to the inner wall of the ventilation duct 13. As the activated carbon plate 15 is blocked by grease on the filter surface, the air pressure inside the ventilation duct 13 will slowly increase, forcing the auxiliary component 11 to deform.

[0023] The impurity removal mechanism 2 includes: a sliding component 21, which is slidably connected to the inner wall of the auxiliary component 11; and a grinding component 22, which is fixedly connected to the side wall of the sliding component 21. When the auxiliary component 11 deforms, it will drive the sliding component 21 and the grinding component 22 to slide downward synchronously.

[0024] The support mechanism 3 includes: an adaptation component 31, which is fixedly connected to the bottom of the polishing component 22; and a limiting component 32, which is fixedly connected to the side wall of the sliding component 21. When the sliding component 21 slides downward, the limiting component 32 rotates due to the restriction of the limiting component 12, and the rotation pressure is transmitted to the adaptation component 31 and the polishing component 22, so that the polishing component 22 polishes the outer wall of the activated carbon plate 15.

[0025] Example 2, please refer to Figures 5-12. This invention is an activated carbon adsorption device for gas oil removal. Based on Example 1, the auxiliary component 11 includes a sliding plug 111 slidably connected to the inner wall of the bottom through hole of the ventilation pipe 13. A spring 112 is fixedly connected to the outer wall of the sliding plug 111. A limit rod 113 is fixedly connected to the inner wall of the ventilation pipe 13. A fixing plate 114 is fixedly connected to the outer wall of the fixed square tube 14. A sealing ring is provided at the sliding position of the ventilation pipe 13 and the sliding plug 111. Under normal conditions, the spring 112 is in an extended state and drives the sliding plug 111 to the highest position. When the air pressure is too high, the air pressure will force the sliding plug 111 to slide downward and squeeze the spring 112 to accumulate potential energy.

[0026] The limiting component 12 includes a slide rod 121 fixedly connected to the inner wall of the ventilation duct 13, a sliding toothed rod 122 slidably connected to the outer wall of the slide rod 121, and a spring 123 fixedly connected to the bottom of the sliding toothed rod 122; wherein, under normal conditions, the spring 123 is in an extended state, forcing the top of the sliding toothed rod 122 to be in contact with the top of the inner wall of the ventilation duct 13.

[0027] The sliding assembly 21 includes a sliding plate 211 slidably connected to the inner wall of the sliding plug 111, and a spring plate 212 fixedly connected to the bottom of the sliding plate 211. To address the issue that the thickness of the activated carbon plate 15 decreases after a single polishing cycle, an adaptation assembly 31 and a polishing assembly 22 are provided inside the equipment. Since the pushing spring 1 inside the spring telescopic rod 221 has a greater pushing spring 2 inside the spring retraction rod 311, the spring telescopic rod 221 can drive the polishing column 223 to press tightly against the outer wall of the activated carbon plate 15 after each polishing cycle. Furthermore, when the spring telescopic rod 221 extends, the spring retraction rod 311 retracts, and the belt 313 undergoes a change in adaptability. Through the application of these components, the polishing column 223 can always remain tightly pressed against the outer wall of the activated carbon plate 15 during use.

[0028] The polishing assembly 22 includes a spring telescopic rod 221 fixedly connected to the side wall of the sliding plate 211. A fixing bracket 222 is fixedly connected to the end of the spring telescopic rod 221 away from the sliding plate 211. A polishing column 223 is rotatably connected to the inner wall of the through hole of the fixing bracket 222. The polishing column 223 is polished only once, after the sliding plug 111 has completely moved downwards under sufficient pressure, and then moves upwards. The polishing column 223 will not deform due to the internal pressure of the ventilation pipe 13 causing deformation of the auxiliary assembly 11. The outer wall of the activated carbon plate 15 is polished, causing the air pressure to drop and the auxiliary component 11 to reset. Subsequently, the previously polished position becomes blocked again, and the auxiliary component 11 deforms. At this time, the same position is polished again, resulting in the phenomenon of repeated polishing of the same position on the activated carbon plate 15. Through the application of the above components, it is ensured that the contact surface of the activated carbon plate 15 will not change too much after each polishing, and that the activated carbon plate 15 will not crack due to uneven polishing when subjected to air pressure.

[0029] The adaptation component 31 includes a spring retraction rod 311 fixedly connected to the bottom of the fixing frame 222. A rotating rod 312 is rotatably connected to the inner wall of the through hole of the spring retraction rod 311, and a belt 313 is sleeved on the outer wall of the rotating rod 312. Taking advantage of the downward sliding characteristic of the sliding plate 211, a groove is formed on the inner wall of the ventilation pipe 13, and the outer wall of the sliding plate 211 slides along the inner wall of the ventilation pipe 13, as shown in Figure 2. The lowest point U of the groove is higher than the lowest point J of the sliding toothed rod 122. Therefore, when the sliding plug 111 drives the sliding plate 211 to slide downward, the outer wall of the sliding plate 211 is restricted by the position U, preventing the sliding plate 211 from sliding downward. At this time, the air pressure inside the ventilation pipe 13 continues to increase, and the pressure forces the sliding plug 111 to press the sliding toothed rod 122 at position J through the fixing plate 114, forcing... The sliding toothed rod 122 slides down a short distance. As the sliding toothed rod 122 slides down, it drives the rotating wheel 322 to rotate clockwise once. Due to the large diameter difference between the rotating ring 325 and the receiving end of the grinding column 223, the grinding column 223 will rotate rapidly. The rotating grinding column 223 will perform the initial grinding on the outer wall of the activated carbon plate 15. After the initial grinding, due to the damage to the oil film on the surface of the activated carbon plate 15, gas can pass through the activated carbon plate 15 again, causing the gas pressure to drop. The spring 112 releases potential energy and slowly drives the sliding plug 111 to slide upward and reset, completing the grinding process. The bottom of the activated carbon plate 15 is ground first, so that after the high pressure accumulates inside the ventilation pipe 13, it can automatically complete the pressure relief process, preventing the activated carbon plate 15 from cracking due to excessive pressure.

[0030] The limiting component 32 includes a second fixing frame 321 fixedly connected to the side wall of the sliding plate 211. A rotating wheel 322 is rotatably connected to the inner wall of the second fixing frame 321. A rotating disk 323 is fixedly connected to the side wall of the rotating wheel 322. A rotating ring 325 is rotatably connected to the side wall of the rotating wheel 322. A second spring plate 324 is fixedly connected to the outer wall of the rotating disk 323. An inclined block 326 is fixedly connected to the inner wall of the rotating ring 325. To address the problem of oil in the gas clogging the activated carbon plate 15, in... The equipment is internally equipped with a pressure-receiving mechanism 1 and a purification mechanism 2. As the activated carbon plate 15 filters air containing oily components over a long period, a thin film will form on the outer wall of the contact surface of the activated carbon plate 15, reducing its ventilation efficiency. This process will slowly increase the air pressure inside the ventilation pipe 13. As the air pressure inside the ventilation pipe 13 increases, the pressure will force the sliding plug 111 to slide downwards along the inner wall of the through-hole of the ventilation pipe 13. The sliding plug 111 will then drive the sliding plate 211 to slide downwards synchronously. Plate 211 drives the rotating wheel 322 to slowly slide downwards along the outer wall of the sliding toothed rod 122. At this time, the rotating wheel 322 is restricted by the sliding toothed rod 122 and will rotate counterclockwise. The counterclockwise rotating wheel 322 drives the rotating disk 323 and the second spring plate 324 to rotate. At this time, the second spring plate 324 will contact the inclined surface of the inclined block 326. Finally, due to the elastic effect of the second spring plate 324, the rotating disk 323 cannot drive the rotating ring 325 to rotate; while the sliding plug 111 moves towards When sliding upwards, the rotating wheel 322 rotates clockwise. The clockwise rotating disk 323 will drive the rotating ring 325 to rotate clockwise through the spring plate 324 and the inclined block 326. The rotating ring 325 drives the grinding column 223 to rotate in the same direction through the belt 313. Through the application of the above components, when the activated carbon plate 15 is blocked, the grinding column 223 will grind the outer wall of the activated carbon plate 15, grinding the outermost layer of the activated carbon plate 15 to prevent oil film blockage from affecting the filtration efficiency.

[0031] One specific application of this embodiment is: before use, the ventilation pipe 13 is fixedly connected to the exhaust port, and it is ensured that the gas entering the ventilation pipe 13 passes through the fixed square pipe 14 and the activated carbon plate 15 and is discharged from the other end.

[0032] To address the problem of oil clogging the activated carbon plate 15 in the gas, a pressure-bearing mechanism 1 and a purification mechanism 2 are installed inside the equipment. As the activated carbon plate 15 filters air containing oily components over a long period, a thin film will form on the outer wall of the contact surface, reducing the ventilation efficiency of the activated carbon plate 15. This process will slowly increase the air pressure inside the ventilation pipe 13. As the air pressure inside the ventilation pipe 13 increases, the pressure will force the sliding plug 111 to slide downwards along the inner wall of the through hole of the ventilation pipe 13. The sliding plug 111 will then drive the sliding plate 211 to slide downwards simultaneously. The sliding plate 211 will drive the rotating wheel 322 to slowly slide downwards along the outer wall of the sliding toothed rod 122. At this time, the rotating wheel 322, constrained by the sliding toothed rod 122, will rotate counterclockwise. The counterclockwise rotating wheel 322... 2. The rotating disk 323 and the second spring plate 324 are rotated. At this time, the second spring plate 324 will contact the inclined surface of the inclined block 326. Ultimately, due to the elasticity of the second spring plate 324, the rotating disk 323 cannot drive the rotating ring 325 to rotate. When the sliding plug 111 slides upward, the rotating wheel 322 rotates clockwise. The clockwise rotating disk 323 will drive the rotating ring 325 to rotate clockwise through the second spring plate 324 and the inclined block 326. The rotating ring 325 drives the grinding column 223 to rotate in the same direction through the belt 313. Through the application of the above components, when the activated carbon plate 15 is blocked, the grinding column 223 will grind the outer wall of the activated carbon plate 15, grinding the outermost layer of the activated carbon plate 15 to prevent oil film blockage from affecting the filtration efficiency.

[0033] Taking advantage of the downward sliding characteristic of the sliding plate 211, a groove is provided on the inner wall of the ventilation pipe 13, and the outer wall of the sliding plate 211 will slide along the inner wall of the ventilation pipe 13, as shown in Figure 2. The lowest point U of the groove is higher than the lowest point J of the sliding toothed rod 122. Therefore, when the sliding plug 111 drives the sliding plate 211 to slide downward, the outer wall of the sliding plate 211 is restricted by the position U, causing the sliding plate 211 to be unable to slide downward. At this time, the air pressure inside the ventilation pipe 13 continues to increase, and the pressure will force the sliding plug 111 to squeeze the sliding toothed rod 122 at position J through the fixed plate 114, forcing the sliding toothed rod 122 to slide downward a short distance. When the sliding toothed rod 122 slides downward, it will drive the sliding plate 122 to slide downward. The rotating wheel 322 rotates clockwise once. Due to the large diameter difference between the rotating ring 325 and the receiving end of the grinding column 223, the grinding column 223 will rotate rapidly. The rotating grinding column 223 will perform the initial grinding on the outer wall of the activated carbon plate 15. After the initial grinding, due to the damage to the oil film on the surface of the activated carbon plate 15, gas can pass through the activated carbon plate 15 again, causing the gas pressure to drop. The spring 112 releases potential energy and slowly drives the sliding plug 111 to slide upward and reset, thus completing the grinding process. The bottom of the activated carbon plate 15 is ground first, so that after the high pressure accumulates inside the ventilation pipe 13, it can complete the pressure relief process on its own, preventing the activated carbon plate 15 from cracking due to excessive pressure.

[0034] The rotating wheel 322 of this invention is designed so that clockwise rotation can drive the grinding column 223 to rotate, while counterclockwise rotation cannot. This ensures that the outer wall of the activated carbon plate 15 can only be ground once after the sliding plug 111 has completely moved down under sufficient pressure. It prevents the grinding column 223 from grinding the outer wall of the activated carbon plate 15 due to deformation of the auxiliary component 11 caused by internal pressure in the ventilation pipe 13, which would cause the air pressure to drop, the auxiliary component 11 to reset, and subsequent blockage at the same grinding position, leading to repeated grinding of the same spot on the activated carbon plate 15. Through the application of the above components, it is ensured that the contact surface of the activated carbon plate 15 does not change excessively after each grinding, and that the outer wall of the activated carbon plate 15 will not crack due to uneven grinding when subjected to air pressure.

[0035] To address the issue that the thickness of the activated carbon plate 15 decreases after a single grinding cycle, an adaptation component 31 and a grinding component 22 are installed inside the equipment. Since the pushing spring 1 inside the spring telescopic rod 221 exerts a greater force than the pushing spring 2 inside the spring retraction rod 311, the spring telescopic rod 221 ensures that the grinding column 223 remains firmly against the outer wall of the activated carbon plate 15 after each grinding cycle. Furthermore, when the spring telescopic rod 221 extends, the spring retraction rod 311 retracts, causing the belt 313 to change its adaptability. Through the application of these components, the grinding column 223 remains firmly against the outer wall of the activated carbon plate 15 throughout the entire process.
