Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a device for harmless treatment of waste gas during activated carbon regeneration. Background Technology

[0002] Activated carbon regeneration is the process of reactivating saturated activated carbon under certain conditions. Activated carbon has been widely used in environmental protection, industry, and civilian applications with considerable success. However, after activated carbon becomes saturated and is replaced, adsorption is a physical process. Therefore, high-temperature steam can be used to desorb impurities from the used activated carbon and restore its original activity for reuse. However, activated carbon regeneration generates waste gas containing acidic and alkaline substances that cannot be directly released into the atmosphere. Before emission, the harmful substances within the waste gas need to be rendered harmless. To better address this issue, a waste gas harmless treatment device for the activated carbon regeneration process is proposed.

[0003] For example, the exhaust gas treatment equipment disclosed in the authorization announcement number CN222641562U includes a purification box and a top cover. An air inlet pipe is provided on one side of the purification box. A collection structure is provided inside the purification box. The collection structure includes a collection cylinder. A fixing frame is fixedly installed inside the collection cylinder. A spring is installed at the lower end of the fixing frame. A closing plate is provided at the lower end of the spring. An air inlet hole is opened at the bottom end of the collection cylinder. Discharge grooves are opened on both sides at the upper end of the air inlet pipe. A cleaning cover is provided at the upper end of the collection cylinder.

[0004] Although it can intercept larger impurities in the water source inside the purification box, it can prevent the sewage pipe from being blocked due to large impurities in the water source;

[0005] However, the existing waste gas treatment equipment does not solve the problems of not being able to stir the neutralizing liquid to make the waste gas and neutralizing liquid more evenly contact each other, not being able to replace the filter blocks quickly without stopping the machine, and not being able to scrape and clean the dust and impurities adhering to the inner wall of the treatment tank, thus affecting the waste gas treatment effect. Utility Model Content

[0006] The purpose of this utility model is to provide a harmless treatment device for waste gas in the activated carbon regeneration process, so as to solve the problems mentioned in the background art, such as the inconvenience of stirring the neutralizing liquid to make the waste gas and neutralizing liquid contact more evenly and the difficulty of replacing the filter block without stopping the machine, and the difficulty of scraping and cleaning the dust and impurities adhering to the inner wall of the treatment tank, which affect the effect of waste gas treatment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a harmless treatment device for waste gas from activated carbon regeneration, comprising a treatment tank and cylinders. Cylinders are symmetrically arranged at the top of the treatment tank, and each cylinder's output end is equipped with a first push arm. A scraping ring is slidably arranged on the inner wall of the treatment tank, and the scraping ring is connected to the first push arm. A drive seat is located at the center of the top of the treatment tank. A servo motor is arranged on the side wall of the drive seat, and a worm gear is arranged at the output end of the servo motor, movably connected to the drive seat. A rotating shaft is movably arranged inside the drive seat on one side of the worm gear, extending into the interior of the treatment tank. A transition air inlet sleeve is arranged at the top of the drive seat, and the rotating shaft is movably connected to the transition air inlet sleeve. A worm wheel is arranged on the surface of the rotating shaft inside the drive seat, and the worm gear meshes with the worm wheel. A valve body is arranged at the top of the treatment tank on one side of the drive seat, and a liquid inlet is arranged at the top of the treatment tank on the other side of the drive seat.

[0008] Preferably, the rotating shaft has an air intake channel inside and an air intake pipe on its side wall.

[0009] Preferably, the surface of the rotating shaft on one side of the air intake pipe is provided with two sets of stirring blades, and the air intake pipe is connected to the air intake channel.

[0010] Preferably, the valve body is provided with two sets of air outlet pipes at the top end, each of the air outlet pipes is provided with a limit cover at the top end, and the limit cover is threadedly connected to the air outlet pipe, and each air outlet pipe is provided with a filter block inside.

[0011] Preferably, a hydraulic rod is movably mounted on the side wall of the valve body, and a second push arm is mounted on the output end of the hydraulic rod.

[0012] Preferably, a linkage arm is provided at the end of the second push arm away from the hydraulic rod, and a hinge shaft is provided at the end of the linkage arm near the second push arm, and the linkage arm is movably connected to the second push arm through the hinge shaft.

[0013] Preferably, a movable shaft is fixedly installed at the end of the linkage arm away from the second push arm, and the movable shaft extends into the interior of the valve body and is movably connected to the valve body.

[0014] Preferably, a valve plate is provided inside the valve body, and the movable shaft is connected to the valve plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the waste gas treatment equipment not only achieves more uniform contact between waste gas and neutralizing liquid through stirring and neutralizing liquid, and allows for rapid replacement of filter blocks without stopping the machine, but also facilitates the scraping and cleaning of dust and impurities adhering to the inner wall of the treatment tank, thus improving the waste gas treatment effect.

[0016] (1) Neutralizing liquid is added into the treatment tank through the liquid inlet. The main component of the neutralizing liquid is ammonia water, which can neutralize the acid and alkali substances in the waste gas generated during the over-regeneration of activated carbon. The waste gas is connected to the transfer inlet sleeve through a pipeline. The waste gas is injected into the neutralizing liquid through the transfer inlet sleeve, the inlet channel and the inlet pipe. The neutralizing liquid neutralizes the acid and alkali of the waste gas. After treatment, the waste gas floats into the open channel inside the valve body and enters a set of outlet pipes. After being filtered by the filter block in the set of outlet pipes, it is discharged into the atmosphere, thus completing the harmless treatment of the waste gas. To ensure more uniform contact between acidic and alkaline substances in the waste gas and the neutralizing liquid, a servo motor drives a worm gear to rotate, which in turn drives a worm wheel, which in turn drives a rotating shaft. An adapter intake sleeve provides movable support for the rotating shaft. While ensuring the shaft rotates, waste gas is still injected into the intake channel. The rotating shaft then drives stirring blades to rotate, which in turn stir the neutralizing liquid, resulting in more uniform contact between the waste gas and the neutralizing liquid. This improves the effectiveness of waste gas neutralization.

[0017] (2) The hydraulic rod drives the second push arm to move, the second push arm drives the linkage arm to rotate through the hinge shaft, and the linkage arm drives the valve plate to rotate through the movable shaft to block the current exhaust channel, so that the gas is discharged from another set of exhaust pipes. Then rotate the corresponding limit cover, unscrew the limit cover, pull out the old filter block, replace it with a new filter block and install it back. This avoids the situation where the equipment stops due to the replacement of filter blocks. When the waste gas enters the neutralizing liquid for neutralization, the dust and impurities inside it will remain in the neutralizing liquid. Over time, the dust and impurities will adhere to the inner wall of the treatment tank. The cylinder drives the first push arm to move, the first push arm drives the scraping ring to move, and the scraping ring scrapes off the dust and impurities adhering to the inner wall of the treatment tank. Then the neutralizing liquid is discharged from the bottom discharge port to complete the cleaning of the treatment tank. This realizes the quick replacement of filter blocks without stopping the machine, and facilitates the scraping and cleaning of the dust and impurities adhering to the inner wall of the treatment tank.

[0028] Example 1

[0029] Please see Figure 1-6This utility model provides an embodiment of a harmless treatment device for waste gas from activated carbon regeneration, comprising a treatment tank 1 and cylinders 3. Cylinders 3 are symmetrically arranged at the top of the treatment tank 1, serving as power drives. Each cylinder 3 has a first push arm 9 mounted at its output end. A scraping ring 2 is slidably arranged on the inner wall of the treatment tank 1, and the scraping ring 2 is connected to the first push arm 9. A drive seat 6 is located at the center of the top of the treatment tank 1, and a servo motor 10 is arranged on the side wall of the drive seat 6, serving as the power drive. The output end of the machine 10 is provided with a worm gear 11, and the worm gear 11 is movably connected to the drive seat 6. A rotating shaft 8 is movably provided inside the drive seat 6 on one side of the worm gear 11, and the rotating shaft 8 extends into the interior of the processing tank 1. A transfer air inlet sleeve 4 is provided at the top of the drive seat 6, and the rotating shaft 8 is movably connected to the transfer air inlet sleeve 4. A worm wheel 12 is provided on the surface of the rotating shaft 8 inside the drive seat 6, and the worm gear 11 and the worm wheel 12 mesh with each other. A valve body 5 is provided at the top of the processing tank 1 on one side of the drive seat 6, and a liquid inlet 7 is provided at the top of the processing tank 1 on the other side of the drive seat 6.

[0030] The rotating shaft 8 has an air intake channel 23 inside, an air intake pipe 21 on the side wall of the rotating shaft 8, and two sets of stirring blades 22 on the surface of the rotating shaft 8 on one side of the air intake pipe 21. The air intake pipe 21 is connected to the air intake channel 23.

[0031] Neutralizing liquid, mainly composed of ammonia, is added into the treatment tank 1 through the liquid inlet 7. This neutralizing liquid neutralizes the acidic and alkaline substances in the waste gas generated during activated carbon regeneration. The waste gas is connected to the transfer inlet sleeve 4 via a pipeline. The waste gas is injected into the neutralizing liquid through the transfer inlet sleeve 4, inlet channel 23, and inlet pipe 21. The neutralizing liquid neutralizes the acid and alkali in the waste gas. After treatment, the waste gas rises into the open channel inside the valve body 5 and enters a set of outlet pipes 18. It is then filtered by the filter block 19 inside the outlet pipes 18 before being discharged into the atmosphere, thus completing the harmless treatment of the waste gas. To ensure better contact between the acidic and alkaline substances in the waste gas and the neutralizing liquid... The servo motor 10 is turned on, and the servo motor 10 drives the worm gear 11 to rotate. Under the mutual meshing of the worm gear 11 and the worm wheel 12, the worm gear 11 drives the worm wheel 12 to rotate, and the worm wheel 12 drives the rotating shaft 8 to rotate. The adapter air intake sleeve 4 provides movable support for the rotating shaft 8. While ensuring the rotation of the rotating shaft 8, exhaust gas is still injected into the air intake channel 23. The rotating shaft 8 drives the stirring blade 22 to rotate, and the stirring blade 22 stirs the neutralization liquid, so that the exhaust gas and the neutralization liquid are in more uniform contact, thereby improving the effect of exhaust gas neutralization treatment. The stirring of the neutralization liquid makes the exhaust gas and the neutralization liquid more uniform in contact, thus improving the effect of exhaust gas treatment.

[0032] The top of the valve body 5 is provided with two sets of air outlet pipes 18. The top of each air outlet pipe 18 is provided with a limit cover 20, and the limit cover 20 is threadedly connected to the air outlet pipe 18. The interior of each air outlet pipe 18 is provided with a filter block 19.

[0033] A hydraulic rod 13 is movably mounted on the side wall of the valve body 5. The hydraulic rod 13 serves as a power drive, and a second push arm 14 is mounted on the output end of the hydraulic rod 13.

[0034] A linkage arm 16 is provided at the end of the second push arm 14 away from the hydraulic rod 13. A hinge shaft 15 is provided at the end of the linkage arm 16 close to the second push arm 14, and the linkage arm 16 is movably connected to the second push arm 14 through the hinge shaft 15. A movable shaft 17 is fixedly installed at the end of the linkage arm 16 away from the second push arm 14, and the movable shaft 17 extends into the interior of the valve body 5 and is movably connected to the valve body 5. A valve plate 24 is provided inside the valve body 5, and the movable shaft 17 is connected to the valve plate 24.

[0035] When filter block 19 needs to be replaced after prolonged use, first open hydraulic rod 13. Hydraulic rod 13 will drive the second push arm 14 to move. The second push arm 14 will drive the linkage arm 16 to rotate via hinge shaft 15. The linkage arm 16 will drive the valve plate 24 to rotate via movable shaft 17, blocking the current exhaust channel and allowing gas to be discharged from another set of exhaust pipes 18. Then, rotate the corresponding limit cover 20. With the limit cover 20 and exhaust pipe 18 threadedly connected, unscrew the limit cover 20, remove the old filter block 19, replace it with a new filter block 19, and install it back. This avoids equipment downtime due to filter block 19 replacement. When the exhaust gas enters the neutralizing liquid for neutralization, the dust and impurities inside will remain in the neutralizing liquid. Over time, the dust and impurities will adhere to the inner wall of the treatment tank 1. At this time, the cylinder 3 is opened, and the cylinder 3 drives the first push arm 9 to move. The first push arm 9 drives the scraping ring 2 to move. With the sliding cooperation between the scraping ring 2 and the treatment tank 1, the scraping ring 2 scrapes off the dust and impurities adhering to the inner wall of the treatment tank 1. Then, the neutralizing liquid is discharged from the bottom outlet to complete the cleaning of the treatment tank 1. This achieves quick replacement of the filter block without stopping the machine and facilitates the scraping and cleaning of the dust and impurities adhering to the inner wall of the treatment tank.

[0036] Work steps

[0037] Neutralizing liquid, mainly composed of ammonia, is added into the treatment tank 1 through the liquid inlet 7. This neutralizing liquid neutralizes the acidic and alkaline substances in the waste gas generated during activated carbon regeneration. The waste gas is connected to the transfer inlet sleeve 4 via a pipeline. The waste gas is injected into the neutralizing liquid through the transfer inlet sleeve 4, inlet channel 23, and inlet pipe 21. The neutralizing liquid neutralizes the acid and alkali in the waste gas. After treatment, the waste gas rises into the open channel inside the valve body 5 and enters a set of outlet pipes 18. It is then filtered by the filter block 19 inside the outlet pipes 18 before being discharged into the atmosphere, thus completing the process. To ensure more uniform contact between the acidic and alkaline substances in the waste gas and the neutralizing liquid, a servo motor 10 drives a worm gear 11 to rotate, which in turn drives a worm wheel 12, which in turn drives a rotating shaft 8. An adapter intake sleeve 4 provides movable support for the rotating shaft 8. While ensuring the rotation of the rotating shaft 8, waste gas is still injected into the intake channel 23. The rotating shaft 8 drives a stirring blade 22 to rotate, which in turn stirs the neutralizing liquid, making the contact between the waste gas and the neutralizing liquid more uniform, thereby improving the neutralization effect of the waste gas and filtration. When filter block 19 needs to be replaced after prolonged use, the hydraulic rod 13 drives the second push arm 14 to move. The second push arm 14 drives the linkage arm 16 to rotate via the hinge shaft 15. The linkage arm 16 drives the valve plate 24 to rotate via the movable shaft 17, blocking the current exhaust passage and allowing gas to be discharged from another set of exhaust pipes 18. Then, rotate the corresponding limit cover 20. With the limit cover 20 and the exhaust pipe 18 threadedly connected, unscrew the limit cover 20, remove the old filter block 19, replace it with a new filter block 19, and install it back. This avoids equipment damage caused by replacing the filter block 19. When a shutdown occurs, the dust and impurities inside the waste gas will remain in the neutralizing liquid during neutralization. Over time, these dust and impurities will adhere to the inner wall of the treatment tank 1. The cylinder 3 drives the first push arm 9 to move, which in turn drives the scraping ring 2 to move. With the sliding cooperation between the scraping ring 2 and the treatment tank 1, the scraping ring 2 scrapes off the dust and impurities adhering to the inner wall of the treatment tank 1. Afterward, the neutralizing liquid is discharged from the bottom outlet to complete the cleaning of the treatment tank 1. The above is the complete usage of the waste gas harmless treatment equipment for the activated carbon regeneration process.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
