Description

Technical Field

[0001] The present invention belongs to the technical field of waste gas treatment, and particularly relates to a high-efficiency VOCs treatment device for a fluidized bed RCO. Background Art

[0002] In China, volatile organic compounds (VOCs) refer to organic compounds with a saturated vapor pressure greater than 70.91 Pa at normal temperature, a boiling point below 50 - 260 °C under a standard atmospheric pressure of 101.3 kPa, and an initial boiling point equal to 250 °C, or any volatile organic solid or liquid at normal temperature and pressure.

[0003] During the use of a fluidized bed ROC, volatile organic compound waste gas is generated, and this part of the volatile organic compounds needs to be treated. The existing treatment method is to pass the volatile organic compound waste gas into a treatment device and adsorb it through an activated carbon particle layer in the treatment device to remove harmful substances inside, and then discharge the treated waste gas. However, when the existing treatment device is in use, due to the flow direction of the waste gas, the side of the activated carbon particles facing the waste gas will be saturated first. As the side of the particles facing the waste gas continues to be saturated, the treatment effect continuously decreases, resulting in the need to replace the activated carbon particles. At this time, the side of the activated carbon particle layer facing away from the waste gas is not completely saturated, so the replaced activated carbon particles are not fully utilized, causing waste.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] The present invention provides a high-efficiency VOCs treatment device for a fluidized bed RCO, as Figures 1 to 5As shown in the figure, it includes a processing box 1. An air inlet pipe 2 communicating with its interior is fixedly installed on the front side of the processing box 1. On the side of the processing box 1 far from the air inlet pipe 2, exhaust pipes 3 communicating with its interior are fixedly installed at equal intervals. A mounting frame 4 is rotatably installed inside one end of the exhaust pipe 3 far from the processing box 1. A sealing ring is provided on the outer side of the mounting frame 4, so that between the mounting frame 4 and the exhaust pipe 3. Inside the mounting frame 4, wire meshes 5 are symmetrically provided. The wire meshes 5 are installed inside the mounting frame 4 by threads. The wire meshes 5 can be rotated and removed to replace the activated carbon particles 6 inside. Activated carbon particles 6 are filled between the two wire meshes 5. The activated carbon particles 6 fill the space formed between the wire meshes 5. An annular plate 7 is fixedly sleeved on the outside of the exhaust pipe 3. On the side of the annular plate 7 far from the processing box 1, cylinders 8 are symmetrically and fixedly installed. A sliding plate is slidably provided inside the cylinder 8. A push rod 9 is fixedly installed on the side of the sliding plate far from the processing box 1. A first spring is sleeved on the outside of the push rod 9. The first spring is located inside the cylinder 8. The ends of adjacent push rods 9 far from the sliding plate are commonly fixedly installed with a movable ring 10. A closing cover 11 is provided inside the movable ring 10. A limiting groove is opened on the outer side of the closing cover 11. A limiting block matched with the limiting groove is fixedly connected to the inner side of the movable ring 10. A second spring 12 is provided on the side of the limiting block close to the cylinder 8. The elastic force of the first spring is greater than the elastic force of the second spring 12. A driving component for driving the closing cover 11 to rotate in cooperation with the closing cover 11 is provided on the outer side of the mounting frame 4. An extrusion component for driving the closing cover 11 to move is provided outside the processing box 1. A closing component for closing the exhaust pipe 3 is provided inside the processing box 1. During use, one exhaust pipe 3 is opened, and the remaining exhaust pipes 3 are closed by the closing component. The waste gas is introduced into the processing box 1 through the air inlet pipe 2. Subsequently, the waste gas passes through the opened exhaust pipe 3 and the activated carbon particles 6, and then is adsorbed and purified and discharged to the outside. The driving of the opened closing cover 11 can be cancelled by the extrusion component. At this time, the deformed first spring releases the acting force to drive the sliding plate, the push rod 9, and the movable ring 10 to move towards the direction close to the exhaust pipe 3, so that the limiting block moves accordingly and presses against the second spring 12 to drive the closing cover 11 to move accordingly. When the closing cover 11 abuts against the exhaust pipe 3 to close it, at this time, as the first spring continues to release the acting force, the continuous movement of the movable ring 10 can be realized, so that the limiting block drives the second spring 12 to deform and generate an acting force. At this time, in cooperation with the driving component, the mounting frame 4 is driven to rotate, so that the wire meshes 5 and the activated carbon particles 6 are driven to rotate, so that the side of the activated carbon particles 6 facing the waste gas is switched. Finally, the acting force of the first spring is released. At this time, the second spring 12 is in a compressed state, completing the switching of the side of the activated carbon particles 6 facing the waste gas. At the same time, the closing component closes the exhaust pipe 3 where the switched activated carbon particles 6 are located. Through the simultaneous closing of the exhaust pipe 3 by the closing component and the closing cover 11, the closing effect of the exhaust pipe 3 is improved. And in the whole process, the exhaust pipe 3 is first closed and then switched. When switching, the unadsorbed and purified waste gas leaking from the gap between the rotating mounting frame 4 and the exhaust pipe 3 can be sealed in the exhaust pipe 3 and will not leak to the outside.By switching the side of the activated carbon particles 6 facing the waste gas, it is ensured that the overall activated carbon particles 6 can be fully utilized. Subsequently, the extrusion assembly drives the next closing cover 11 to move away from the exhaust pipe 3, so that the closing cover 11 is finally opened, the movable ring 10 is reset, and the second spring 12 is reset. During the opening process of the closing cover 11, the movable ring 10 drives the push rod 9 and the sliding plate to move accordingly, compressing the first spring to deform and generate a force. At this time, the waste gas introduced can be purified and discharged through the opened exhaust pipe 3. By switching the use of the exhaust pipe 3, the replacement frequency of the activated carbon particles 6 in the exhaust pipe 3 can be reduced, and the burden on workers can be reduced. Similarly, through the continuous drive of the extrusion assembly, the switching use of the exhaust pipe 3 can be realized, and the side of the activated carbon particles 6 facing the waste gas can be switched to ensure the full use of the activated carbon particles 6 and avoid waste.

[0027] Such as Figures 3 to 4As shown, the driving assembly includes a rotating rod fixedly connected to the middle of the top of the mounting frame 4, the top of the rotating rod extends to the outside of the exhaust pipe 3 and is fixedly installed with a gear 13, the outer sleeve of the rotating rod is provided with a one-way bearing, the inner ring of the one-way bearing is fixedly connected to the rotating rod, the outer side of the one-way bearing is fixedly connected to the exhaust pipe 3, a transverse plate 14 is fixedly installed on the inner side of the movable ring 10, a carrier plate is fixedly installed at an equal distance on the top of the transverse plate 14, a shaft is rotatably installed on the top of the carrier plate, and the bottom of the shaft extends to the bottom of the carrier plate and is fixedly installed with teeth 15 that cooperate with the gear 13 The outer sleeve of the shaft is provided with a first torsion spring 16, and the two ends of the first torsion spring 16 are fixedly connected to the shaft and the carrier plate respectively. The side of the tooth 15 close to the horizontal plate 14 is fixedly installed with an arc block 17, and the arc surface of the arc block 17 is arranged on the side close to the exhaust pipe 3. The arc block 17 is in conflict with the horizontal plate 14. When the closing cover 11 is in conflict with the exhaust pipe 3 and stops moving, the first spring continuously releases the force to enable the movable ring 10 to continue to move, so that the movable ring 10 moves in the direction close to the exhaust pipe 3 along with the push rod 9 and the slide plate. , so that the limit block compresses the second spring 12 to deform it and generate a force, and the movable ring 10 drives the cross plate 14, the carrier plate, the shaft rod, and the teeth 15 to move accordingly. When the teeth 15 collide with the gear 13, due to the setting of the arc surface block 17, the teeth 15 cannot rotate forward, so that when the teeth 15 moves, it can drive the gear 13 to drive the rotating rod and the mounting frame 4 to rotate forward, so that the mounting frame 4 can be driven to rotate and drive the activated carbon particles 6 inside to switch to the side facing the exhaust gas. When the movable ring 10 moves away When the gear 15 moves away from the exhaust pipe 3 and is reset, the tooth 15 also moves accordingly. Due to the presence of the one-way bearing, the rotating rod cannot be reversed, thereby making the gear 13 unable to reverse. After the tooth 15 contacts the gear 13, the tooth 15 is squeezed and drives the shaft to reverse, causing the first torsion spring 16 to deform and generate a force, causing the tooth 15 to be staggered from the gear 13. When the tooth 15 is separated from the gear 13, the first torsion spring 16 releases the force to drive the shaft and the tooth 15 to rotate and reset, thereby finally realizing the one-way drive of the mounting frame 4.

[0028] like Figures 1 to 2As shown in the figure, the extrusion assembly includes a motor 18 fixedly connected to the middle of the bottom end of the processing box 1. The processing box 1 is set as a circular box body. A connecting rod 19 is rotatably installed in the middle of the bottom wall of the processing box 1. The bottom end of the connecting rod 19 is fixedly connected to the top end of the output shaft of the motor 18. The top end of the connecting rod 19 is fixedly installed with an L-shaped rod 20. A driving plate 32 is fixedly installed at one end of the L-shaped rod 20 away from the connecting rod 19. A driving rod 21 that cooperates with the driving plate 32 is fixedly installed at the top of the movable ring 10. Start the motor 18 to make its output shaft rotate forward, driving the connecting rod 19 and the L-shaped rod 20 to rotate, thereby driving the driving plate 32 to rotate. When the driving plate 32 abuts against the driving rod 21, it can extrude the driving rod 21, causing the driving rod 21 and the movable ring 10 to move away from the exhaust pipe 3. The movable ring 10 drives the limiting block to move accordingly, and the deformed second spring 12 recovers. Subsequently, the limiting block abuts against the wall of the limiting groove, driving the closing cover 11 away from the exhaust pipe 3. As the movable ring 10 moves, the push rod 9 and the sliding plate move accordingly, compressing the first spring to deform and generate a force, so as to open the exhaust pipe 3.

[0029] As Figure 1 shown, the driving plate 32 is specifically set as a plate-shaped member with an arc surface on one side. The arc surface can abut against the driving rod 21, so that after the driving plate 32 abuts against the driving rod 21, it can cooperate with the arc surface to extrude it, enabling the driving rod 21 to move away from the exhaust pipe 3.

[0030] As Figure 2 shown, the closing assembly includes a rotating groove opened at the lower part of one end of the exhaust pipe 3 away from the mounting bracket 4. A movable shaft is rotatably installed inside the rotating groove. An outer fixed sleeve of the movable shaft is provided with a cover plate 22 matching the exhaust pipe 3. Second torsion springs are sleeved on both sides of the movable shaft. The two ends of the second torsion spring are respectively fixedly connected to the movable shaft and the wall of the rotating groove. An opening assembly for driving the cover plate 22 to rotate and open is provided outside the connecting rod 19. When the connecting rod 19 rotates, it can cooperate with the opening assembly to drive the cover plate 22 to rotate downward and open, driving the movable shaft to rotate. At this time, the second torsion spring deforms to generate a force.

[0031] As Figure 2 shown, the opening assembly includes a straight rod 23 fixedly connected to the outside of the connecting rod 19. A magnet ball 24 is fixedly installed at one end of the straight rod 23 away from the connecting rod 19. The cover plate 22 is made of iron. After the connecting rod 19 drives the straight rod 23 and the magnet ball 24 to rotate to a position corresponding to the cover plate 22, stop the rotation of the motor 18. At this time, the magnet ball 24 is located in front of the cover plate 22. At this time, the magnet ball 24 magnetically adsorbs the cover plate 22 to make it rotate downward and open, driving the movable shaft to rotate. At this time, the second torsion spring deforms to generate a force. When the motor 18 starts, its output shaft rotates to drive the straight rod 23 and the magnet ball 24 away from the cover plate 22. The cover plate 22 loses the adsorbed force, and the deformed second torsion spring releases the force to drive the movable shaft and the cover plate 22 to rotate and reset to close the exhaust pipe 3.

[0032] As shown Figure 2 in the figure, mounting openings corresponding to the exhaust pipe 3 are equidistantly arranged at the top of the treatment box 1. A cylinder block 25 is fixedly installed in the mounting opening. A discharge pipe 26 communicating with the bottom of the cylinder block 25 is provided at the bottom of the cylinder block 25. A suction pipe 27 is provided at the bottom of the cylinder block 25. The suction pipe 27 is a rigid pipe. One end of the suction pipe 27 away from the cylinder block 25 extends outside the treatment box 1 and is fixedly connected to a flexible pipe. A straight pipe 28 communicating with the top of the closing cover 11 is fixedly installed at the top of the closing cover 11. The straight pipe 28 is a rigid pipe. The top of the straight pipe 28 is communicated with one end of the flexible pipe. Check valves are provided inside both the straight pipe 28 and the discharge pipe 26. A piston 29 is provided inside the cylinder block 25. A pressing assembly for driving the piston 29 to move in the vertical direction is provided at the top of the piston 29. After the exhaust pipe 3 is closed and the side of the activated carbon particles 6 facing the waste gas is switched, as the L-shaped rod 20 continues to rotate, the pressing assembly can be cooperated to drive the piston 29 to rise, so that the check valve located in the discharge pipe 26 is closed at this time, and the check valve located in the straight pipe 28 is opened. As the piston 29 continues to rise, the unprocessed waste gas leaking due to the rotation of the mounting frame 4 in the closing cover 11 at this time is extracted, so that this part of the waste gas is drawn back into the cylinder block 25 through the straight pipe 28, the flexible pipe, and the suction pipe 27, realizing the recovery of the leaked unprocessed waste gas, so that when the closing cover 11 is opened, this part of the waste gas will not escape to the outside. When the L-shaped rod 20 rotates to the next cylinder block 25, the pressing assembly at this time presses the piston 29 in the next cylinder block 25 to descend, so that the waste gas extracted inside is extruded outwards, so that the check valve located in the discharge pipe 26 is opened at this time, and the check valve located in the straight pipe 28 is closed. As the piston 29 continues to descend, the waste gas enters the treatment box 1 through the discharge pipe 26, and then is adsorbed and purified again through the corresponding exhaust pipe 3 and the activated carbon particles 6 and discharged. As the L-shaped rod 20 rotates, the unprocessed waste gas leaking due to the rotation of the mounting frame 4 in the closing cover 11 can be extracted and recovered, and this part of the waste gas is introduced into the treatment box 1 again, and is adsorbed and purified through the exhaust pipe 3 and the activated carbon particles 6 and discharged, which can avoid the unprocessed waste gas leaking during the switching from escaping to the outside.

[0033] As shown Figures 1 to 2As shown, the pressing assembly includes a push rod 30 fixedly mounted on the top of the piston 29, and a third spring is sleeved on the outside of the push rod 30. The two ends of the third spring are fixedly connected to the piston 29 and the top wall of the cylinder body 25 respectively. The top of the push rod 30 extends outside the cylinder body 25, and an arc block 31 for squeezing the push rod 30 is fixedly mounted on the bottom of the L-shaped rod 20. One side of the arc block 31 is provided with an arc extrusion surface. After the L-shaped rod 20 drives the arc block 31 to rotate until it completely leaves the push rod 30, the closing cover 11 has closed the exhaust pipe 3 at this time, and the activated carbon particles 6 inside have completed the switching to face the exhaust gas surface. At this time, the deformed third spring releases the force to drive the piston 29 and the push rod 30 to rise and reset. When the L-shaped rod 20 drives the arc extrusion surface of the arc block 31 to collide with the push rod 30, the arc extrusion surface is used to squeeze the push rod 30 to drive the piston 29 to descend, and at the same time, the third spring is pulled to deform it and generate a force.

[0034] Working principle: when in use, the exhaust gas is introduced into the treatment box 1 through the intake pipe 2, and then the exhaust gas passes through the opened exhaust pipe 3 and the activated carbon particles 6, and then is discharged to the outside after being adsorbed and purified. After the treatment is completed, the motor 18 is started to make its output shaft rotate forward to drive the connecting rod 19 and the L-shaped rod 20 to rotate, thereby driving the driving plate 32 to rotate, so that the driving plate 32 leaves the driving rod 21. At this time, the first spring in the deformed state releases the force to drive the slide plate, the push rod 9, and the movable ring 10 to move in the direction close to the exhaust pipe 3, so that the limit block moves accordingly and presses against the second spring 12 to drive the closing cover 11 to move accordingly. When the closing cover 11 conflicts with the exhaust pipe 3 to close it, at this time, as the first spring continues to release the force, the movable ring 10 can continue to move, so that The limit block is driven to squeeze the second spring 12 to deform it and generate a force. As the first spring continuously releases the force, the movable ring 10 can continue to move, so that the movable ring 10 moves in the direction close to the exhaust pipe 3 along with the push rod 9 and the slide plate, so that the limit block continues to compress the second spring 12 to deform it and generate a force. The movable ring 10 drives the cross plate 14, the carrier plate, the shaft rod, and the teeth 15 to move accordingly. When the teeth 15 collide with the gear 13, due to the setting of the arc surface block 17, the teeth 15 cannot rotate forward, so that when the teeth 15 moves, the gear 13 can be driven to drive the rotating rod and the mounting frame 4 to rotate forward, so that the mounting frame 4 can be driven to rotate and drive the side of the internal activated carbon particles 6 facing the exhaust gas to switch. At the same time, the sealing component seals the exhaust pipe 3 where the activated carbon particles 6 are switched. During the whole process, the exhaust pipe 3 is first sealed and then switched, so that when switching, the unabsorbed and purified exhaust gas leaking from the gap between the rotating mounting frame 4 and the exhaust pipe 3 can be sealed in the exhaust pipe 3 and will not leak to the outside. By switching the side of the activated carbon particles 6 facing the exhaust gas, it is ensured that the activated carbon particles 6 as a whole can be fully utilized. As the driving plate 32 continues to rotate, when the driving plate 32 conflicts with the next driving rod 21, it can squeeze the driving rod 21, so that the driving rod 21 and the movable ring 10 are driven to move in the direction away from the exhaust pipe 3, and the movable ring 10 drives the limit block to move accordingly, and the deformed second spring 12 recovers The limit block then pushes against the limit groove wall to drive the closing cover 11 away from the exhaust pipe 3. With the movement of the movable ring 10, the push rod 9 and the slide plate move accordingly to compress the first spring to deform it and generate a force, so that the next adjacent exhaust pipe 3 is opened. When the movable ring 10 moves to a direction away from the exhaust pipe 3 and resets, the tooth 15 moves accordingly. Due to the existence of the one-way bearing, the rotating rod cannot be reversed, thereby making the gear 13 unable to reverse. After the tooth 15 contacts the gear 13, the tooth 15 is squeezed and drives the shaft rod to reverse, so that the first torsion spring 16 deforms and generates a force, so that the tooth 15 is staggered with the gear 13. When the tooth 15 is separated from the gear 13, the first torsion spring 16 releases its force to drive the shaft rod and the tooth 15 to rotate and reset.The closing component corresponding to the exhaust pipe 3 that is simultaneously opened cancels the closing of the exhaust pipe 3, and the next exhaust pipe 3 is fully opened, enabling the treatment and discharge of waste gas. As the driving plate 32 continuously moves, the switching use of the activated carbon particles 6 on the side facing the waste gas can be realized, enabling the full use of the activated carbon particles 6 and the switching use of the activated carbon particles 6 located in different exhaust pipes 3, thereby reducing the replacement frequency of the activated carbon particles 6 in the exhaust pipe 3 and reducing the burden on workers. After the L-shaped rod 20 drives the arc-shaped block 31 to rotate until it completely leaves the ejector rod 30, at this time, the closing cover 11 has closed the exhaust pipe 3, and the internal activated carbon particles 6 have completed the switching of the side facing the waste gas. At this time, the deformed third spring releases the acting force to drive the piston 29 and the ejector rod 30 to rise and reset, causing the one-way valve located in the discharge pipe 26 to close and the one-way valve located in the straight pipe 28 to open. As the piston 29 continuously rises, the untreated waste gas leaking due to the rotation of the mounting bracket 4 in the closing cover 11 at this time is extracted, and this part of the waste gas is drawn back into the cylinder block 25 through the straight pipe 28, the hose, and the extraction pipe 27, realizing the recovery of the leaking untreated waste gas, so that when the closing cover 11 is opened, this part of the waste gas will not escape to the outside. When the arc-shaped pressing surface of the arc-shaped block 31 driven by the L-shaped rod 20 abuts against the ejector rod 30, the ejector rod 30 is pressed by cooperating with the arc-shaped pressing surface to drive the piston 29 to descend, and at the same time, the third spring is pulled to deform and generate an acting force, so that the extracted waste gas inside is extruded outward, causing the one-way valve located in the discharge pipe 26 to open and the one-way valve located in the straight pipe 28 to close. As the piston 29 continuously descends, the waste gas enters the treatment box 1 through the discharge pipe 26, and then is adsorbed and purified again through the corresponding exhaust pipe 3 and the activated carbon particles 6 and discharged. As the L-shaped rod 20 rotates, the extraction and recovery of the untreated waste gas leaking due to the rotation of the mounting bracket 4 in the closing cover 11 can be realized, and this part of the waste gas is re-introduced into the treatment box 1, and after being adsorbed and purified through the exhaust pipe 3 and the activated carbon particles 6, it is discharged, avoiding the escape of the untreated waste gas leaking during the switching to the outside.
