Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and in particular to an activated carbon adsorption system and process for waste gas. Background Technology

[0002] Activated carbon adsorption is a common method for treating waste gas. Adsorption utilizes porous materials such as activated carbon, diatomaceous earth, and anthracite to adsorb organic gas molecules onto their surface, thereby purifying the gas. Advantages: High purification rate, practical and convenient, simple operation, and low investment. Disadvantages: Significant system pressure loss leading to high energy consumption, difficulty in determining the saturation point of the adsorbent, limited adsorbent capacity, and high operating costs.

[0003] Activated carbon is an excellent adsorbent. It is manufactured from raw materials such as charcoal, various fruit shells, and high-quality coal through a series of physical and chemical processes including crushing, sieving, catalyst activation, rinsing, drying, and screening. Activated carbon possesses both physical and chemical adsorption properties, selectively adsorbing various substances in the gas and liquid phases to achieve purposes such as decolorization, purification, disinfection, deodorization, and decontamination. The activated carbon adsorption method utilizes activated carbon as a physical adsorbent to concentrate harmful substances generated during electrostatic spraying on the solid-phase surface, thereby purifying and treating waste gas. This adsorption process occurs at the solid-gas interface.

[0004] Activated carbon is divided into two categories: granular and fibrous. Granular activated carbon has more uniform pores, including both micropores and macropores ranging from 0.5 to 5 nanometers. Its specific surface area is generally 600 to 1600 square meters per gram. Since the gas being treated diffuses from the outside in, the distance traveled is relatively long, resulting in slower adsorption and desorption. Oxidized granular activated carbon has a stronger adsorption capacity. Fibrous activated carbon, on the other hand, has smaller pores and a larger specific surface area. It adsorbs through intermolecular attraction, without chemical reactions, making it a physical adsorption process.

[0005] Activated carbon adsorption devices are used during electrostatic spraying. When waste gas passes through an activated carbon layer, hydrocarbons are adsorbed by the activated carbon, and the purified gas is then released into the atmosphere. Small adsorption devices typically use vertical adsorption tanks; large adsorption devices typically use horizontal adsorption tanks.

[0006] As the activated carbon adsorption process progresses, the equipment resistance increases slowly. When the activated carbon becomes saturated, the equipment resistance reaches its maximum value, and the purification efficiency is essentially lost thereafter. Therefore, a differential pressure measurement system is installed at the equipment's inlet and outlet to detect and display the pressure difference between the inlet and outlet of the exhaust gas, allowing for timely replacement of the activated carbon.

[0007] Because activated carbon is regenerable, it can be regenerated and recycled using an activated carbon desorption device when there is a large amount of activated carbon used, high concentration of waste gas, and short adsorption saturation time. Using an activated carbon desorption device not only saves operating costs but also allows for the recovery of adsorbed waste gas, thus avoiding secondary pollution.

[0008] The adsorption effect of activated carbon adsorption devices is affected by a variety of factors, mainly including the following: The properties of the activated carbon, such as its specific surface area, pore structure, and surface chemical properties, all influence its adsorption performance. Generally, activated carbon with a larger specific surface area, more developed pore structure, and more active surface chemical properties exhibits better adsorption performance. The properties of the waste gas, such as its temperature, humidity, flow rate, and concentration, all affect the adsorption effect of activated carbon. Generally, lower temperatures, lower humidity, slower flow rates, and lower concentrations of waste gas result in better adsorption by activated carbon. Adsorption time is also crucial; the longer the adsorption time, the more organic molecules the activated carbon adsorbs, leading to a better adsorption effect. However, excessively long adsorption times can cause activated carbon saturation, requiring regeneration or replacement. Operating conditions, such as pressure and temperature, also affect the adsorption effect of activated carbon. Generally, increasing pressure and decreasing temperature are beneficial for improving the adsorption performance of activated carbon.

[0009] For example, application number 202022865906.3 discloses an activated carbon adsorption system for waste gas, including an adsorption tower. Both ends of one side of the adsorption tower have locking grooves, and both ends of the other side of the adsorption tower are fixedly installed with connecting rods. Both ends of the bottom front of the adsorption tower are hinged to both ends of one side of the filling plate via hinges. A pick-up block is fixedly installed at the center of the top front of the filling plate. This utility model's activated carbon adsorption system for waste gas features an airtight gasket that ensures good sealing of the gas guide pipe. The installation of a cooling plate inside the convex gas outlet pipe prevents the waste gas temperature from being too high and scalding the convex gas outlet pipe. The gas guide pipe evenly distributes the waste gas in the adsorption tower, solving the problems of poor airflow and blockage of the activated carbon packing. The adsorption towers can be connected in parallel via the locking grooves and connecting rods on both sides. The connecting grooves and connecting blocks facilitate series installation of the adsorption towers, offering diverse installation methods and demonstrating the flexibility of engineering installation.

[0010] However, current activated carbon adsorption systems for waste gas often suffer from unreasonable waste gas flow path design. Within the same volume of adsorption chamber, the contact area between the activated carbon and the waste gas is not ideal, resulting in low waste gas treatment efficiency, large adsorption box volume, high manufacturing cost, and low overall automation level. In particular, replacing activated carbon is labor-intensive, time-consuming, affects personal safety, and seriously damages the surrounding environment. Summary of the Invention

[0011] The technical problem to be solved by this invention is to optimize the design of the waste gas flow path, increase the contact area between the activated carbon and the waste gas in the same volume of adsorption chamber, improve the waste gas treatment rate of the equipment, reduce the volume of the adsorption box, reduce the manufacturing cost, improve the overall automation level of the equipment, especially in the process of replacing activated carbon, reduce the intensity of manual labor, reduce the replacement time, improve personal safety protection, and reduce the damage to the surrounding environment of the equipment.

[0023] A process for using an activated carbon adsorption system for waste gas includes the following steps:

[0024] S1. The exhaust gas enters the air inlet chamber through the air inlet, and after passing through the hydrophobic air sieve on the baffle plate, it enters the activated carbon adsorption chamber.

[0025] S2. The exhaust gas enters the intake chamber through the intake port, and after being adsorbed and filtered by the first filter box, the second filter box, the third filter box and the fourth filter box in the activated carbon adsorption chamber, it enters the exhaust chamber and is discharged through the exhaust port.

[0026] S3. The exhaust gas entering the air intake chamber enters the first air intake channel and the second air intake channel through the first air intake port and the second air intake port, respectively. The exhaust gas entering the first air intake channel enters the first air outlet channel through the first filter box. The exhaust gas passing through the second filter box enters the second air outlet channel. The exhaust gas entering the second air intake channel enters the second air outlet channel through the third filter box. The exhaust gas passing through the fourth filter box enters the third air outlet channel. The first air outlet channel, the second air outlet channel, and the third air outlet channel converge in the air outlet chamber and flow out through the air outlet.

[0027] S4. When it is necessary to replace the activated carbon, the automatic door mechanism opens, and the activated carbon to be replaced enters the guide trough through the discharge port and enters the next process along the guide inclined plate.

[0028] S5. The activated carbon that slides down the guide plate enters the discharge hopper. After it is discharged, the walking motor drives the connecting rod shaft to rotate through the steering reducer, thereby driving the rotating wheel to move linearly along the ground rail and deliver the activated carbon.

[0029] S6. When activated carbon needs to be replaced, the main push cylinder drives the movable door to move linearly along the axis of the main push cylinder. The pulleys and limit wheels on the movable door move linearly in the sliding guide groove, so that the movable door closes or opens with the fixed channel steel, realizing the closing and opening of the automatic door mechanism. The horizontal push cylinder and the lifting cylinder drive the guide channel steel and the movable door to move up and down, thereby ensuring that the movable door disengages from the adsorption body during the closing and opening of the automatic door mechanism. When locked, it is sealed by the sealing gasket.

[0030] S7. The reduction motor drives the pinion to rotate, and the pinion meshes with the connecting rod rack, thereby driving the movable guide rod to slide linearly on the guide rod boss. The connecting rod is movably sleeved on the guide protrusion on the movable guide rod through the second connecting rod groove. When the movable guide rod slides linearly on the guide rod boss, the second connecting rod groove drives the locking block to rotate along the corner hole. When it rotates to a horizontal state, the main push cylinder pushes the locking block into the U-shaped locking groove, the flat push cylinder and the lifting cylinder descend, the locking block descends along the pressing groove, the sealing gasket seals, and then the reduction motor drives the locking block to rotate along the corner hole to a vertical state for locking action; the opening action is the opposite.

[0031] S8. When timed dust removal is required, the oscillating cylinder reciprocates over a short distance, causing vibration of the multi-stage impact rod, thereby causing the first filter box, the second filter box, the third filter box, and the fourth filter box to vibrate.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. By setting up a multi-channel fixed adsorption mechanism, the waste gas flow path is optimized. Within the same volume of adsorption chamber, the contact area between the adsorption activated carbon and the waste gas is maximized, thereby improving the waste gas treatment rate of the equipment. Under the same waste gas treatment capacity requirements, the volume of the adsorption box is reduced, thus reducing manufacturing costs.

[0034] 2. By setting up an automatic door mechanism, the manual labor intensity and replacement time for replacing adsorption activated carbon are greatly reduced. From the discharge of used activated carbon to the feeding of new activated carbon, the automatic door opening and automatic feeding method greatly reduces labor, shortens replacement time, improves equipment utilization, and enhances the automation and intelligence of the equipment.

[0035] 3. By setting up a movable guide rod, a connecting rack and pinion, and a connecting rod, a simple linkage mechanism is used to achieve synchronous action of multiple mechanisms. The structure is simple, the design is ingenious, and automation is achieved, which greatly reduces the structural and manufacturing costs of the automated door mechanism.

[0036] 4. By setting locking blocks and U-shaped locking grooves, a simple mechanism is used to achieve automatic locking, which reduces problems such as air leakage in the automatic door mechanism caused by cylinder failure. During the locking period, the main push cylinders are not ventilated, which reduces the frequency of cylinder use and improves the service life of the cylinders.

[0037] 5. By setting up an automatic feeding and discharging mechanism, there is no need for manual replacement of adsorption activated carbon. This not only improves the overall automation level of the equipment, but also effectively reduces the harm to the human body caused by opening the door to replace adsorption activated carbon and the attached waste gas, thus improving the safety of the equipment.

[0038] 6. By setting up a guide chute and guide ramp, the activated carbon to be replaced is guided into the discharge car. While ensuring effective material discharge, the accuracy of material discharge is improved. Compared with manual material replacement, the hygiene environment around the equipment is improved.

[0039] 7. By setting up a water baffle mechanism, moisture in the gas entering the adsorption box is blocked, effectively preventing the activated carbon adsorption pores from being blocked by dust and water in the waste gas, and also effectively preventing the equipment inside the adsorption box from rusting.

[0040] 8. By setting up a vibration cleaning mechanism, the vibration cylinder impacts the multi-stage impact rods, which in turn causes the filter box to vibrate. The timed impacts effectively remove particulate matter from the exhaust gas adhering to the filter box and the pores of the activated carbon, improving the utilization rate of activated carbon and enhancing the self-cleaning ability of the equipment.

The fixed support beam 301 is fixedly mounted on the adsorption frame 102. The fixed channel steel 302 is fixedly mounted on the fixed support beam 301. Multiple U-shaped locking grooves 303 are provided on the fixed channel steel 302, arranged in a straight line. Two horizontal push cylinders 304 are provided, respectively fixedly mounted on both sides of the fixed support beam 301. Two sets of lifting cylinders 305 are provided, each set containing multiple cylinders, evenly distributed on the adsorption frame 102. Two sets of guide channel steel 306 are provided, respectively fixedly mounted on the movable ends of the two sets of lifting cylinders 305 and the movable ends of the horizontal push cylinders 304, allowing for linear up-and-down movement along the lifting cylinders 305.

One end of the main push cylinder 314 is fixedly mounted on the adsorption frame 102, and the other end is fixedly mounted on the movable door 307. The U-shaped locking groove 30... 3. A pressing groove 328 is provided at the bottom center. In use, the main push cylinder 314 drives the movable door 307 to move linearly along the axis of the main push cylinder 314. The pulleys 310 and limit wheels 312 on the movable door 307 move linearly in the sliding guide groove 313, so that the movable door 307 closes or opens with the fixed channel steel 302, realizing the closing and opening of the automatic door mechanism 3. The flat push cylinder 304 and the lifting cylinder 305 drive the guide channel steel 306 and the movable door 307 to move up and down, thereby ensuring that the movable door 307 disengages from the adsorption body 1 during the closing and opening of the automatic door mechanism 3. When locked, it is sealed by the sealing gasket 308.By installing an automatic door mechanism, the manual labor intensity and replacement time for replacing activated carbon are greatly reduced. From the discharge of used activated carbon to the feeding of new activated carbon, the automatic door opening and feeding system significantly reduces labor costs, shortens replacement time, and improves equipment utilization. Simultaneously, it enhances the automation and intelligence of the equipment.

[0063] In some embodiments, see Figure 9The automatic door mechanism 3 further includes a door end channel steel 315, a first connecting rod groove 316, a guide rod boss 317, a movable guide rod 318, a connecting rod rack 319, a motor bracket 320, a reduction motor 321, a pinion 322, a connecting rod 323, a second connecting rod groove 324, a guide protrusion 325, a locking block 326, and a corner hole 327. The door end channel steel 315 is fixedly installed on the side of the movable door 307 away from the main push cylinder 314. The top surface of the door end channel steel 315 has multiple sets of first connecting rod grooves 316. Multiple sets of guide rod bosses 317 are provided and fixedly installed on the door end channel steel 315. The movable guide rod 318 is movably sleeved on multiple sets of guide rods. Within the boss 317, the connecting rod rack 319 is fixedly mounted on the movable guide rod 318, the motor bracket 320 is fixedly mounted on the movable door 307, the reduction motor 321 is fixedly mounted on the motor bracket 320, the pinion 322 is fixedly mounted on the shaft end of the reduction motor 321 and meshes with the connecting rod rack 319 for transmission, multiple sets of connecting rods 323 are provided, and each connecting rod 323 is provided with a second connecting rod groove 324, multiple sets of guide protrusions 325 are fixedly mounted on the movable guide rod 318, and the connecting rods 323 are movably sleeved on the guide protrusions 325 through the second connecting rod grooves 324, and the locking block 326 is provided. Multiple sets are fixedly installed at the end of the connecting rod 323 away from the guide protrusion 325, and movably sleeved within the corner hole 327. In use, the reduction motor 321 drives the pinion 322 to rotate, and the pinion 322 meshes with the connecting rod rack 319, thereby driving the movable guide rod 318 to slide linearly on the guide rod protrusion 317. The connecting rod 323 is movably sleeved on the guide protrusion 325 on the movable guide rod 318 through the second connecting rod groove 324. When the movable guide rod 318 slides linearly on the guide rod protrusion 317, the second connecting rod groove 324 drives the locking block 326 along the corner hole. The cylinder 327 rotates within the corner hole 327. When it reaches a horizontal position, the main push cylinder 314 pushes the locking block 326 into the U-shaped locking groove 303. The horizontal push cylinder 304 and the lifting cylinder 305 descend, and the locking block 326 descends along the pressing groove 328. The sealing gasket 308 seals, and then the reduction motor 321 drives the locking block 326 to rotate vertically within the corner hole 327 to perform the locking action. The opening action is the reverse. By setting a movable guide rod, connecting rod rack, and connecting rod, a simple linkage mechanism is used to achieve synchronous action of multiple mechanisms. The structure is simple, the design is ingenious, and automation is achieved, greatly reducing the structural and manufacturing costs of the automatic door mechanism. By setting a locking block and U-shaped locking groove, a simple mechanism is used to achieve the automatic locking function, reducing problems such as air leakage in the automatic door mechanism caused by cylinder failure. During the locking period, the main push cylinder is not ventilated, reducing the frequency of cylinder use and improving the cylinder service life.

[0064] In some embodiments, see Figure 8 The adsorption body 1 also includes a guide trough 110 and a guide inclined plate 111. Two sets of guide troughs 110 are provided, located on the adsorption frame 102 and at the outlet 109, respectively. Each set of guide troughs 110 has two guide inclined plates 111 arranged symmetrically inwards on its inner bottom surface. During use, when activated carbon needs to be replaced, the automatic door mechanism 3 opens, and the activated carbon to be replaced enters the guide trough 110 through the outlet 109 and proceeds along the guide inclined plate 111 to the next process. By setting up the guide trough and guide inclined plate, the activated carbon to be replaced is guided into the discharge cart, ensuring effective material discharge while improving the accuracy of material discharge. Compared to manual material replacement, this improves the hygiene of the area around the equipment.

[0065] In some embodiments, see Figure 12 The waste gas activated carbon adsorption system also includes an automatic feeding and discharging mechanism 4, which includes a ground rail 401, a discharge cart 402, a travel motor 403, a steering reducer 404, a connecting rod shaft 405, wheel seats 406, rotating wheels 407, and a discharge hopper 408. Two sets of ground rails 401 are symmetrically arranged at the bottom of the adsorption frame 102. The discharge cart 402 is movably mounted on the ground rails 401 via multiple sets of rotating wheels 407, moving linearly along the ground rails 401. The travel motor 403 is fixedly mounted on the discharge cart 402, and its output end is fixedly connected to the steering reducer 404. The vertical output end of the steering reducer 404 is fixedly connected to the connecting rod shaft 405. Two sets of wheel seats 406 are provided, each set containing two wheels, fixedly mounted on the bottom surface of the discharge cart 402. The rotating wheels 407 are connected via... The short shaft is movably mounted on the wheel seat 406. One set of rotating wheels 407 is movably sleeved on both ends of the connecting rod shaft 405 via bearings to drive the trolley. The other set of rotating wheels 407 is movably mounted on the wheel seat 406 via bearings. The discharge hopper 408 is fixedly mounted on the discharge trolley 402. In use, activated carbon sliding down the guide plate 111 enters the discharge hopper 408. After discharge, the travel motor 403 drives the connecting rod shaft 405 to rotate via the steering reducer 404, thereby driving the rotating wheels 407 to move linearly along the ground rail 401 and discharging the activated carbon. By setting up an automatic feeding and discharging mechanism, there is no need for manual replacement of the adsorbed activated carbon. This not only improves the overall automation level of the equipment but also effectively reduces the harm to the human body caused by opening the door to replace the adsorbed activated carbon and the attached exhaust gas, thus improving the safety of the equipment.

[0066] In some embodiments, see Figure 6The activated carbon adsorption system for waste gas also includes a water baffle mechanism 5, which includes a water baffle slot 501, a water baffle plate 502, an air vent 503, a hydrophobic air sieve 504, and a water baffle cover plate 505. The adsorption body 1 has a water baffle slot 501 on its side. The water baffle plate 502 passes through the water baffle slot 501 and is fixedly installed inside the adsorption body 1 at the air inlet chamber 105. Multiple sets of air vents 503 are provided on the water baffle plate 502. A hydrophobic venting screen 504 is provided, and a water baffle cover 505 is fixedly installed at the water baffle slot 501. In use, the exhaust gas enters the air inlet chamber 105 through the air inlet 103, and enters the activated carbon adsorption chamber 107 after passing through the hydrophobic venting screen 504 on the water baffle plate 502. By setting the water baffle mechanism, the moisture in the gas entering the adsorption box is blocked, which effectively prevents the activated carbon adsorption pores from being blocked by dust and water in the exhaust gas, and at the same time effectively prevents the equipment in the adsorption box from rusting.

[0067] In some embodiments, see Figure 2 , Figure 13 The activated carbon adsorption system for waste gas also includes a vibration cleaning mechanism 6, which includes multi-stage impact rods 601 and a vibration cylinder 602. Multiple sets of multi-stage impact rods 601 are movably mounted on the side wall of the adsorption body 1, fitted with sealing rings, and fixedly connected to the first filter box 201, the second filter box 202, the third filter box 203, and the fourth filter box 204. The vibration cylinder 602 is fixedly mounted on the side wall of the adsorption body 1, with its shaft end contacting and engaging with the shaft end of the multi-stage impact rods 601. In operation, the vibrating cylinder 602 reciprocates over short distances, causing vibrations in the multi-stage impact rod 601, which in turn causes the first filter box 201, the second filter box 202, the third filter box 203, and the fourth filter box 204 to vibrate. By setting up a vibration cleaning mechanism, the vibrating cylinder impacts the multi-stage impact rod 601, simultaneously causing the filter boxes to vibrate. The timed impacts effectively remove particulate matter from the exhaust gas adhering to the filter boxes and adsorbing the pores of the activated carbon, improving the utilization rate of activated carbon and enhancing the self-cleaning ability of the equipment.

[0068] A process for using an activated carbon adsorption system for waste gas includes the following steps:

[0069] S1. The exhaust gas enters the air inlet 105 through the air inlet 103, and enters the activated carbon adsorption chamber 107 after passing through the hydrophobic air sieve 504 on the baffle plate 502.

[0070] S2. The exhaust gas enters the intake chamber 105 through the intake port 103, and after being adsorbed and filtered by the first filter box 201, the second filter box 202, the third filter box 203 and the fourth filter box 204 in the activated carbon adsorption chamber 107, it enters the exhaust chamber 106 and is discharged through the exhaust port 104.

[0071] S3. The exhaust gas entering the air intake chamber 105 enters the first air intake channel 212 and the second air intake channel 213 through the first air intake port 210 and the second air intake port 211, respectively. The exhaust gas entering the first air intake channel 212 enters the first air outlet channel 214 through the first filter box 201. The exhaust gas passing through the second filter box 202 enters the second air outlet channel 215. The exhaust gas entering the second air intake channel 213 enters the second air outlet channel 215 through the third filter box 203. The exhaust gas passing through the fourth filter box 204 enters the third air outlet channel 216. The first air outlet channel 214, the second air outlet channel 215, and the third air outlet channel 216 converge in the air outlet chamber 106 and flow out through the air outlet 104.

[0072] S4. When it is necessary to replace the activated carbon, the automatic door mechanism 3 opens, and the activated carbon to be replaced enters the guide trough 110 through the discharge port 109 and enters the next process along the guide inclined plate 111.

[0073] S5. The activated carbon that slides down the guide plate 111 enters the discharge hopper 408. After it is discharged, the walking motor 403 drives the connecting rod shaft 405 to rotate through the steering reducer 404, thereby driving the rotating wheel 407 to move linearly along the ground rail 401 and deliver the activated carbon.

[0074] S6. When the activated carbon needs to be replaced, the main push cylinder 314 drives the movable door 307 to move linearly along the axis of the main push cylinder 314. The pulley 310 and the limiting wheel 312 on the movable door 307 move linearly in the sliding guide groove 313, so that the movable door 307 and the fixed channel steel 302 can be closed or opened, realizing the closing and opening of the automatic door mechanism 3. The horizontal push cylinder 304 and the lifting cylinder 305 drive the guide channel steel 306 and the movable door 307 to move up and down, thereby ensuring that during the closing and opening of the automatic door mechanism 3, the movable door 307 is disengaged from the adsorption body 1, and when locked, it is sealed by the sealing gasket 308.

[0075] S7. The reduction motor 321 drives the pinion 322 to rotate. The pinion 322 meshes with the connecting rod rack 319, thereby driving the movable guide rod 318 to slide linearly on the guide rod boss 317. The connecting rod 323 is movably sleeved on the guide protrusion 325 on the movable guide rod 318 through the second connecting rod groove 324. When the movable guide rod 318 slides linearly on the guide rod boss 317, the second connecting rod groove 324 drives the... The locking block 326 rotates within the corner hole 327. When it reaches a horizontal position, the main push cylinder 314 pushes the locking block 326 into the U-shaped locking groove 303. The flat push cylinder 304 and the lifting cylinder 305 descend, and the locking block 326 descends along the pressing groove 328. The sealing gasket 308 seals, and then the reduction motor 321 drives the locking block 326 to rotate within the corner hole 327 to a vertical position for locking. The opening action is the reverse.

[0076] S8. When timed dust removal is required, the oscillating cylinder 602 reciprocates over a short distance, causing vibration of the multi-stage impact rod 601, thereby causing the first filter box 201, the second filter box 202, the third filter box 203, and the fourth filter box 204 to vibrate.

[0077] Obviously, the above embodiments are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, these obvious variations or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.

The exhaust gas passing through the second filter box (202) enters the second air outlet channel (215). The exhaust gas entering the second air intake channel (213) enters the second air outlet channel (215) through the third filter box (203). The exhaust gas passing through the fourth filter box (204) enters the third air outlet channel (216). The first air outlet channel (214), the second air outlet channel (215), and the third air outlet channel (216) converge in the air outlet chamber (106) and flow out through the air outlet (104). S4. When it is necessary to replace the activated carbon, the automatic door mechanism (3) opens, and the activated carbon to be replaced enters the guide trough (110) through the discharge port (109) and enters the next process along the guide inclined plate (111). S5. Activated carbon that slides down the guide plate (111) enters the discharge hopper (408). After discharge, the walking motor (403) drives the connecting rod shaft (405) to rotate through the steering reducer (404), thereby driving the rotating wheel (407) to move linearly along the ground rail (401) and deliver the activated carbon. S6. When it is necessary to replace the activated carbon, the main push cylinder (314) drives the movable door (307) to move linearly along the axis of the main push cylinder (314). The pulley (310) and the limiting wheel (312) on the movable door (307) move linearly in the sliding guide groove (313) so that the movable door (307) closes or opens with the fixed channel steel (302), thereby realizing the closing and opening of the automatic door mechanism (3). The flat push cylinder (304) and the lifting cylinder (305) drive the guide channel steel (306) and the movable door (307) to move up and down, thereby ensuring that during the closing and opening of the automatic door mechanism (3), the movable door (307) is separated from the adsorption body (1), and when locked, it is sealed by the sealing gasket (308). S7. The geared motor (321) drives the pinion (322) to rotate. The pinion (322) meshes with the connecting rod rack (319), thereby driving the movable guide rod (318) to slide linearly on the guide rod boss (317). The connecting rod (323) is movably sleeved on the guide protrusion (325) on the movable guide rod (318) through the second connecting rod groove (324). When the movable guide rod (318) slides linearly on the guide rod boss (317), the second connecting rod groove (324) drives the... The locking block (326) rotates within the corner hole (327). When it reaches a horizontal position, the main push cylinder (314) pushes the locking block (326) into the U-shaped locking groove (303). The flat push cylinder (304) and the lifting cylinder (305) descend, and the locking block (326) descends along the pressing groove (328). The sealing gasket (308) seals, and then the reduction motor (321) drives the locking block (326) to rotate within the corner hole (327) to a vertical position for locking. The opening action is the opposite. S8. When timed dust removal is required, the oscillating cylinder (602) reciprocates over a short distance, causing vibration of the multi-stage impact rod (601), thereby causing the first filter box (201), the second filter box (202), the third filter box (203), and the fourth filter box (204) to vibrate.
