Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, specifically to an activated carbon adsorption tower for chemical product processing. Background Technology

[0002] Activated carbon adsorption towers are environmental protection devices that utilize the adsorption properties of activated carbon to treat pollutants such as waste gas and wastewater. They are widely used in pollution control in industries such as chemical, printing, coating, pharmaceutical, and food processing. In chemical product processing, activated carbon adsorption towers are crucial equipment in the refining and purification stages, and their adsorption efficiency directly determines the purity of the product, production costs, and process stability. Especially when processing complex chemical raw materials, efficient adsorption is essential for removing impurities and improving product quality. Activated carbon adsorption towers achieve the separation and removal of harmful substances through the adsorption of pollutant molecules by the porous structure of activated carbon.

[0003] For example, patent document CN220589485U discloses an activated carbon adsorption tower. This adsorption tower installs several carbon plate supports with activated carbon plates inside the tower body, and installs adsorption pipe one, adsorption pipe two, and two adsorption pipes three for waste gas flow inside the tower body. This allows waste gas to enter adsorption pipe one, adsorption pipe two, and the two adsorption pipes three, and then pass through the activated carbon plates between the corresponding adsorption pipe one, adsorption pipe two, or two adsorption pipes three, thereby adsorbing and treating the odor in the waste gas.

[0004] In the aforementioned adsorption tower, the gas directly contacts the activated carbon plates through the adsorption pipes. This causes some areas of the activated carbon in the tower to reach adsorption saturation prematurely, while the activated carbon in other areas fails to fully exert its adsorption effect due to uneven gas distribution or surface covering. This uneven adsorption state necessitates frequent replacement of the activated carbon in the adsorption tower, resulting in low production efficiency. Summary of the Invention

[0005] In view of this, the present invention provides an activated carbon adsorption tower for chemical product processing, which solves the technical problem in the prior art where the gas to be adsorbed is directly introduced into the activated carbon, causing the activated carbon in some areas to reach adsorption saturation prematurely, thus requiring frequent replacement of the activated carbon.

[0006] To solve the above technical problems, the present invention provides an activated carbon adsorption tower for chemical product processing, including a tower body, a storage cylinder disposed in the tower body, the storage cylinder containing activated carbon, a rotating cylinder rotatably connected to the tower body, a spiral plate wound around the outer wall of the rotating cylinder, gas being adsorbed by the activated carbon after rotating and flowing with the spiral plate, and a drive assembly for driving the rotating cylinder to rotate on the tower body.

[0007] Both the upper and lower surfaces of the spiral plate are covered with sponge layers. A cleaning frame is slidably mounted on the inner wall of the tower body. Two cleaning rods are mounted on the cleaning frame, and the two cleaning rods abut against the upper and lower sponge layers of the spiral plate respectively. Two spiral grooves are opened on the outer wall of the rotating cylinder, located above and below the spiral plate respectively. The two cleaning rods are slidably connected to the two spiral grooves respectively.

[0008] By adopting the above technical solution, activated carbon is stored in the storage cylinder. After the gas to be adsorbed enters the tower body, it contacts the lower end of the spiral plate, and after rotating and flowing with the spiral plate, it reaches the upper end of the spiral plate, and then contacts the storage cylinder. After being adsorbed by the activated carbon in the storage cylinder, it is discharged.

[0009] Because the gas to be adsorbed may carry fine particulate impurities such as dust, oil mist, and aerosols, these impurities, after entering the adsorption tower with the gas, come into contact with the activated carbon and gradually deposit on the surface of the activated carbon. With prolonged operation, these impurities form a coating layer on the outer surface of the activated carbon, directly reducing the effective specific surface area of ​​the activated carbon available for gas adsorption and causing some areas of the activated carbon in the adsorption tower to reach adsorption saturation prematurely. As the gas to be adsorbed flows with the rotating spiral plate, it facilitates the separation of particulate impurities from the gas. This invention installs sponge layers on both the upper and lower surfaces of the spiral plate, which adsorb particulate impurities.

[0010] The drive assembly drives the rotating drum to rotate forward, which in turn drives the spiral plate to rotate. Because the cleaning frame and the inner wall of the tower body are slidably connected, one end of the cleaning rod is connected to the cleaning frame, and the other end is slidably connected to the spiral groove. When the spiral plate rotates, it drives the cleaning rod downwards through threaded engagement with the cleaning rod. The compression of the sponge layer by the two cleaning rods forces the accumulated particulate impurities out of the sponge layer, keeping it loose and porous. This allows the sponge layer to adsorb particulate impurities in the subsequent gas, reducing contact between impurities and activated carbon. When the cleaning rod reaches the lower end of the spiral plate, the drive assembly drives the rotating drum to rotate in the opposite direction, causing the cleaning rod to move upwards and gradually to the upper end of the spiral plate.

[0011] This invention extends the flow path of the gas to be adsorbed by adding a spiral plate. On the one hand, this increases the gas dispersion, ensuring uniform contact between the gas and activated carbon, thus reducing the likelihood of the activated carbon reaching adsorption saturation prematurely in certain areas. On the other hand, it facilitates the separation of particulate impurities from the gas. These separated impurities are adsorbed by the sponge layer, reducing direct contact between them and the activated carbon. This helps minimize the formation of a coating layer on the activated carbon surface, maintaining its effective specific surface area. Simultaneously, the cleaning rod periodically cleans the sponge layer, keeping it in an adsorption state and reducing the risk of contamination and premature saturation of the activated carbon by particulate impurities, thereby extending the activated carbon replacement cycle.

[0012] Preferably, the spiral plate is provided with multiple gas distribution holes for gas to pass through.

[0013] By adopting the above technical solution, the gas distribution holes, acting as airflow dispersion channels, can divide the concentrated inflow of gas into multiple fine streams. As the gas flows and rotates along the spiral plate, some gas can directly pass through the spiral plate via the gas distribution holes, breaking the single spiral flow path and forming a composite airflow pattern of mainstream rotation and perforated diversion. This design helps reduce excessive concentration of gas within the spiral channel due to the obstruction of the spiral plate, thereby increasing gas dispersion and ensuring full utilization of the effective specific surface area of ​​the activated carbon, reducing the likelihood of localized activated carbon reaching adsorption saturation prematurely.

[0014] Preferably, two spiral plates are provided, with the two spiral plates rotating in the same direction and arranged in a staggered circumferential pattern. The upper ends of the two spiral plates are located on both sides of the rotating drum. Two cleaning frames are also provided, with the two cleaning frames and the two spiral plates corresponding one to one.

[0015] By employing the above technical solution, the two spiral plates rotate in the same direction but are staggered circumferentially, creating a double-helix superimposed flow field for the gas within the tower. The upper ends of the two spiral plates are located on opposite sides of the rotating drum. After being guided by the spiral plates, the gas eventually flows out from the areas on either side of the rotating drum and enters the activated carbon adsorption zone. This design creates a bidirectional flow path for the gas within the tower, preventing excessive gas accumulation on one side of the rotating drum, thus improving gas dispersion and reducing the likelihood of the activated carbon reaching adsorption saturation prematurely in certain areas.

[0016] Preferably, a feeding cylinder is provided inside the rotating drum, with a discharge port 1 at the bottom of the feeding cylinder and a discharge port 2 at the top of the rotating drum. A linear actuator 1 is provided inside the tower body to drive the feeding cylinder to rise and fall. After the feeding cylinder moves upward, the activated carbon in the feeding cylinder enters the storage cylinder in sequence through the discharge port 1 and the discharge port 2.

[0017] By adopting the above technical solution, activated carbon is placed inside the feeding cylinder. When the concentration of pollutants in the gas to be adsorbed is high, the linear actuator drives the feeding cylinder upward. The discharge port one on the feeding cylinder and the discharge port two on the rotating drum are connected. Since discharge port one is located at the bottom of the feeding cylinder, the activated carbon in the feeding cylinder sequentially enters the storage cylinder through discharge port one and discharge port two, replenishing the activated carbon in the storage cylinder and improving the adsorption capacity. When the activated carbon in the storage cylinder is close to saturation, fresh activated carbon can be added to the feeding cylinder. The feeding cylinder adopts a first-in, first-out dynamic feeding mechanism. When the system needs to replenish activated carbon, the feeding cylinder will preferentially discharge the activated carbon particles that were loaded first. This orderly material circulation method avoids the problem of some activated carbon being repeatedly used or left idle for a long time due to fixed positions during the feeding process, ensuring that the activated carbon particles are utilized evenly.

[0018] Preferably, the storage cylinder includes a bottom plate disposed between the inner wall of the tower body and the outer wall of the rotating cylinder, and a baffle disposed on the bottom plate and near the inner wall of the tower body, wherein the side of the bottom plate near the outer wall of the rotating cylinder slides and rotates to seal with the outer wall of the rotating cylinder.

[0019] By adopting the above technical solution, an annular gap exists between the inner wall of the tower and the outer wall of the rotating drum. The bottom plate is laid in this gap, transforming it into a storage area. A baffle near the inner wall of the tower forms a lateral barrier, preventing activated carbon from overflowing. The side of the bottom plate closest to the outer wall of the rotating drum slides and rotates to seal against the outer wall, relying on the outer wall of the rotating drum to create a barrier against the activated carbon. After the feed cylinder moves upward and outlet one connects with outlet two, the activated carbon in the feed cylinder can enter the storage cylinder.

[0020] Preferably, a support plate is installed above the storage cylinder inside the tower body. The support plate is equipped with a linear actuator 2 that drives the storage cylinder to rise and fall. The upper end of the feeding cylinder is provided with a feed inlet. After the storage cylinder moves up, the activated carbon in the storage cylinder enters the feeding cylinder in sequence through the discharge outlet 2 and the feed inlet.

[0021] By adopting the above technical solution, when the concentration of pollutants in the gas to be adsorbed is low, the linear actuator one drives the feeding cylinder to move downward, so that the inlet on the feeding cylinder is connected to the outlet two on the rotating drum. At the same time, the linear actuator two drives the storage cylinder to move upward, and the activated carbon in the storage cylinder enters the feeding cylinder in sequence through the outlet two and the inlet. This can realize small-dose, on-demand replenishment of activated carbon, reduce unnecessary consumption of fresh activated carbon, and reduce operating costs.

[0022] Preferably, the upper end of the feeding cylinder is provided with a cover plate, and the cover plate, the cylinder wall of the feeding cylinder, and the bottom plate are all provided with vent holes.

[0023] By adopting the above technical solution, the gas to be adsorbed enters the storage cylinder through the vent holes on the bottom plate, is adsorbed by the activated carbon, and then is discharged upward through the vent holes on the cylinder wall and the cover plate in sequence.

[0024] Preferably, the lower end of the feeding cylinder is provided with an end plate, the upper end face of the end plate is conical, and a support rod is installed on the lower end face of the end plate. A linear driver is installed inside the rotating cylinder, and the output shaft of the linear driver is connected to the support rod.

[0025] By adopting the above technical solution, the upper end face of the end plate is conical. With the guiding effect of the inclined surface, the activated carbon in the feeding cylinder can slide to all sides under the action of gravity and flow to the discharge port of the feeding cylinder, which is conducive to the activated carbon in the feeding cylinder smoothly entering the storage cylinder.

[0026] Preferably, a demister is provided inside the tower body above the storage cylinder, an air outlet is provided above the demister on the tower body, and an air inlet is provided below the spiral plate on the tower body.

[0027] By adopting the above technical solution, the gas to be adsorbed enters the tower body from the inlet, rises under the guidance of the spiral plate, and is then adsorbed by the activated carbon in the storage cylinder. The demister is located above the storage cylinder to intercept the tiny droplets that may be carried in the gas. The gas treated by the demister is discharged from the outlet.

[0028] Preferably, the drive assembly includes a drive motor mounted on the tower body, a drive gear mounted on the output shaft of the drive motor, and a driven gear mounted on the rotating drum, wherein the drive gear and the driven gear mesh.

[0029] By adopting the above technical solution, the drive motor drives the active gear to rotate, which in turn drives the driven gear to rotate, thereby driving the rotating drum to rotate. When it is necessary to clean the sponge layer, the drive motor can rotate in both directions, which can drive the rotating drum to rotate in both directions, thereby causing the cleaning rod to move down or up. When the cleaning rod moves down, it cleans the sponge layer, and when it moves up, it resets.

[0030] The beneficial effects of the above-described technical solution of the present invention are as follows:

[0031] 1. This invention extends the flow path of the gas to be adsorbed by adding a spiral plate. On the one hand, this increases the dispersion of the gas, allowing it to contact the activated carbon evenly, thus reducing the likelihood of the activated carbon reaching adsorption saturation prematurely in certain areas. On the other hand, it facilitates the separation of particulate impurities from the gas. The separated particulate impurities are adsorbed by the sponge layer, reducing direct contact between the particulate impurities and the activated carbon. At the same time, the cleaning rod regularly cleans the sponge layer, helping to maintain its adsorption state and reducing the risk of the activated carbon being contaminated by particulate impurities and becoming saturated prematurely, thereby extending the replacement cycle of the activated carbon.

[0032] 2. The spiral plate is provided with gas distribution holes. When the gas flows along the spiral plate in a rotating manner, some of the gas can pass directly through the spiral plate through the gas distribution holes, breaking the single spiral flow path and forming a composite airflow pattern of mainstream rotation and perforated flow. This helps to reduce the excessive concentration of gas in the spiral channel due to the obstruction of the spiral plate, thereby increasing the dispersion of the gas and making full use of the effective specific surface area of ​​the activated carbon, reducing the situation where the local activated carbon reaches the adsorption saturation state too early.

[0033] 3. The present invention has two spiral plates, with the upper ends of the two spiral plates located on both sides of the rotating cylinder. After being guided by the spiral plates, the gas will eventually flow out from the areas on both sides of the rotating cylinder and enter the activated carbon adsorption zone, so that the gas forms a bidirectional flow path in the tower. This helps to reduce the excessive accumulation of gas on one side of the tower, improves the dispersion of the gas, and reduces the situation where the local activated carbon reaches the adsorption saturation state too early.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will be described in conjunction with the embodiments of the present invention. Figures 1-8 The technical solutions of the embodiments of the present invention will be clearly and completely described.

[0044] Example

[0045] This embodiment provides an activated carbon adsorption tower for chemical product processing, such as... Figure 1 and Figure 2 As shown, it includes a tower body 1 and a storage cylinder 2.

[0046] like Figure 1 and Figure 2As shown, the storage cylinder 2 is located inside the tower body 1, and the storage cylinder 2 stores activated carbon. A demister 12 is located above the storage cylinder 2 inside the tower body 1, and an air outlet 13 is located above the demister 12 on the tower body 1. An air inlet 11 is located at the bottom of the tower body 1. A manhole 18 is provided on the tower body 1 for personnel to enter.

[0047] like Figure 1 and Figure 2 As shown, the gas to be adsorbed enters the tower body 1 through the inlet 11 and is adsorbed by the activated carbon in the storage cylinder 2. The demister 12 is located above the storage cylinder 2 to intercept the tiny droplets that may be carried in the gas. The gas treated by the demister 12 is discharged from the outlet 13.

[0048] like Figure 2 As shown, a rotating cylinder 3 is rotatably connected inside the tower body 1, and the axis of the rotating cylinder 3 is parallel to the axis of the tower body 1.

[0049] like Figure 2 As shown, two spiral plates 4 are spirally wound on the outer wall of the rotating cylinder 3. One side of the spiral plate 4 is fixedly connected to the rotating cylinder 3, and the other side of the spiral plate 4 abuts against the inner wall of the tower body 1.

[0050] like Figure 2 and Figure 6 As shown, the two spiral plates 4 rotate in the same direction and are arranged in a staggered circumferential pattern. The lower ends of the two spiral plates 4 are located on both sides of the rotating drum 3, and the upper ends of the two spiral plates 4 are also located on both sides of the rotating drum 3.

[0051] like Figure 2 and Figure 6 As shown, after the gas to be adsorbed enters the tower body 1, it is guided by the spiral plate 4, that is, it flows from the lower end of the spiral plate 4 along the rotation path of the spiral plate 4, and then enters the storage cylinder 2 from the upper end of the spiral plate 4, and is adsorbed by the activated carbon.

[0052] like Figure 2 and Figure 6 As shown, the spiral plate 4 can extend the flow path of the gas to be adsorbed, which is beneficial to increase the dispersion of the gas and make the gas contact the activated carbon evenly, thereby helping to reduce the situation where the activated carbon reaches the adsorption saturation state too early in some areas.

[0053] like Figure 2As shown, the gas to be adsorbed may carry fine particulate impurities such as dust, oil mist, and aerosols. These impurities, after entering the adsorption tower with the gas, come into contact with the activated carbon and form a coating layer on the outer surface of the activated carbon. This not only reduces the effective specific surface area of ​​the activated carbon available for gas adsorption but also causes some areas of the activated carbon in the adsorption tower to reach adsorption saturation prematurely. The spiral plate 4 extends the gas flow path. As the gas rises in the spiral, the particulate impurities it contains move downwards under the action of gravity and centrifugal force, which is beneficial for the separation of particulate impurities from the gas.

[0054] like Figure 2 and Figure 6 As shown, this embodiment sets two spiral plates 4 to form two flow paths. The gas flows from the lower end of the two spiral plates 4 along the two flow paths, and then flows out from the upper end of the two spiral plates 4, that is, from both sides of the rotating cylinder 3. This can avoid excessive accumulation of gas on one side of the rotating cylinder 3, which is beneficial to improve the dispersion of the gas. This helps to reduce the situation where the activated carbon reaches the adsorption saturation state too early in some areas and extends the replacement cycle of the activated carbon.

[0055] like Figure 2 , Figure 8 As shown, the spiral plate 4 is provided with multiple gas distribution holes 42 for gas to pass through. These gas distribution holes 42 act as airflow dispersion channels, dividing the concentrated inflow of gas into multiple fine streams. When the gas rotates along the spiral plate 4, some gas can pass directly through the spiral plate 4 via the gas distribution holes 42, breaking the single spiral flow path and forming a composite airflow pattern of mainstream rotation and perforated diversion. This helps reduce the excessive concentration of gas within the spiral channel due to the obstruction of the spiral plate 4, thereby increasing gas dispersion and ensuring full utilization of the effective specific surface area of ​​the activated carbon, reducing the likelihood of the activated carbon reaching adsorption saturation prematurely in certain areas.

[0056] like Figure 3 and Figure 8 As shown, a sponge layer 41 is installed on both the upper and lower ends of the spiral plate 4. During the rotation and flow of the gas to be adsorbed along with the spiral plate 4, particulate impurities are facilitated to separate from the gas, and the sponge layer 41 adsorbs the particulate impurities. Additionally, the gas can also come into contact with the sponge layer 41 as it passes through the gas distribution holes 42, where the sponge layer 41 also adsorbs particulate impurities.

[0057] like Figure 2 As shown, both the upper and lower ends of the rotating cylinder 3 are open, and the lower end of the rotating cylinder 3 is rotatably connected to the bottom of the tower body 1. The rotating cylinder 3 is driven by the drive assembly 5.

[0058] like Figure 2 As shown, the drive assembly 5 includes a drive motor 51, a drive gear 52, and a driven gear 53.

[0059] Among them, such as Figure 2 As shown, the drive motor 51 is mounted on the outside of the tower body 1, and the output shaft of the drive motor 51 extends into the tower body 1 and is rotatably connected to the tower body 1. The driving gear 52 is mounted on the output shaft and located inside the tower body 1. The driven gear 53 is mounted on the rotating drum 3. The driven gear 53 and the driving gear 52 mesh perpendicularly. The driven gear 53 and the driving gear 52 can be bevel gears as used in the prior art to achieve their perpendicular meshing.

[0060] like Figure 2 As shown, the drive motor 51 drives the drive gear 52 to rotate, the drive gear 52 drives the driven gear 53 to rotate, and in turn drives the drum 3 to rotate.

[0061] like Figure 4 and Figure 6 As shown, two cleaning racks 14 are slidably mounted on the inner wall of the tower body 1. The two cleaning racks 14 are located near the upper ends of the two spiral plates 4, and the two cleaning racks 14 correspond one-to-one with the two spiral plates 4. The upper end of the same spiral plate 4 is located above the lower end, that is, the upper and lower ends are aligned vertically.

[0062] like Figure 6 and Figure 7 As shown, two cleaning rods 15 are installed on the cleaning frame 14. The two cleaning rods 15 are arranged parallel to each other vertically. The two cleaning rods 15 abut against the upper and lower sponge layers 41 of the spiral plate 4, respectively, that is, the spiral plate 4 and the sponge layer 41 are located between the two cleaning rods 15. Two spiral grooves 31 are respectively opened on the outer wall of the rotating drum 3 above and below the spiral plate 4. The ends of the two cleaning rods 15 are slidably connected to the two spiral grooves 31 respectively.

[0063] like Figure 2 , Figure 4 and Figure 6 As shown, the drive assembly 5 drives the rotating drum 3 to rotate in the forward direction, and the rotating drum 3 drives the spiral plate 4 to rotate. Since the cleaning frame 14 and the inner wall of the tower body 1 are slidably connected, one end of the cleaning rod 15 is connected to the cleaning frame 14, and the other end of the cleaning rod 15 is slidably connected to the spiral groove 31. When the spiral plate 4 rotates, it drives the cleaning rod 15 to move spirally downward through the threaded engagement with the cleaning rod 15. The upper and lower cleaning rods 15 squeeze the sponge layer 41, squeezing out the accumulated particulate impurities from the sponge layer 41. As the cleaning rod 15 continuously spirals downward, it gradually squeezes out the particulate impurities in the sponge layer 41 and makes them fall to the bottom of the tower body 1, keeping the sponge layer 41 in a loose and porous state. This allows it to adsorb particulate impurities in the subsequent gas, reduce the contact between impurities and activated carbon, and extend the replacement cycle of activated carbon.

[0064] like Figure 2 and Figure 4As shown, when the cleaning rod 15 reaches the lower end of the spiral plate 4, the drive assembly 5 drives the rotating drum 3 to rotate in the opposite direction, causing the cleaning rod 15 to move upward and gradually move to the upper end of the spiral plate 4, so that the cleaning rod 15 returns to its original position.

[0065] like Figure 3 and Figure 4 As shown, the storage cylinder 2 includes a bottom plate 21 disposed between the inner wall of the tower body 1 and the outer wall of the rotating cylinder 3, and a baffle 22 disposed on the bottom plate 21 and near the inner wall of the tower body 1. The side of the bottom plate 21 near the outer wall of the rotating cylinder 3 is slidably and rotatably sealed with the outer wall of the rotating cylinder 3. There is an annular gap between the inner wall of the tower body 1 and the outer wall of the rotating cylinder 3, and the bottom plate 21 is laid in this gap, transforming it into a storage area.

[0066] like Figure 2 and Figure 3 As shown, a feeding cylinder 6 is provided inside the rotating drum 3. The axis of the feeding cylinder 6 is collinear with the axis of the rotating drum 3, and the feeding cylinder 6 and the rotating drum 3 are connected by a sliding rotation seal. A support column 67 is provided inside the feeding cylinder 6. The lower end of the support column 67 is installed at the bottom of the tower body 1. The support column 67 passes through the feeding cylinder 6 and is slidably connected to the feeding cylinder 6.

[0067] like Figure 4 and Figure 5 As shown, the upper end of the feeding cylinder 6 is provided with a cover plate 61, and the lower end of the feeding cylinder 6 is provided with an end plate 62. The upper end face of the end plate 62 is conical, and the upper end face of the end plate 62 gradually tilts from top to bottom toward the side away from the axis of the feeding cylinder 6.

[0068] like Figure 2 and Figure 4 As shown, a support rod 63 is installed on the lower end face of the end plate 62. A linear actuator 64 is installed at the bottom of the tower body 1 and inside the rotating drum 3. The output shaft of the linear actuator 64 is connected to the support rod 63. Two linear actuators 64 are provided, located on both sides of the rotating drum 3 respectively.

[0069] like Figure 3 and Figure 5 As shown, the lower part of the feeding cylinder 6 and above the end plate 62 is provided with a discharge port 65. Multiple discharge ports 65 are arranged around the periphery of the feeding cylinder 6. The rotating cylinder 3 is provided with a discharge port 32. Multiple discharge ports 32 are also provided and arranged around the periphery of the rotating cylinder 3.

[0070] like Figure 4 As shown, when the concentration of pollutants in the gas to be adsorbed is high, after the linear actuator 64 drives the feeding cylinder 6 to move upward, the discharge port 65 is connected to the discharge port 32, and the activated carbon in the feeding cylinder 6 can enter the storage cylinder 2.

[0071] like Figure 3 and Figure 5As shown, the upper end face of the end plate 62 is conical. With the guiding effect of the inclined surface, the activated carbon in the feeding cylinder 6 can slide to the surroundings under the action of gravity, which is conducive to the concentrated flow to the discharge port 65 of the feeding cylinder 6, thus facilitating the smooth entry of the activated carbon in the feeding cylinder 6 into the storage cylinder 2.

[0072] like Figure 2 and Figure 4 As shown, a support plate 16 is installed above the storage cylinder 2 inside the tower body 1. A second linear actuator 17 for driving the storage cylinder 2 to rise and fall is provided on the support plate 16. Two linear actuators 17 are provided, located on opposite sides of the rotating drum 3. In this embodiment, both the first linear actuator 64 and the second linear actuator 17 are either pneumatic cylinders or hydraulic cylinders.

[0073] like Figure 2 and Figure 3 As shown, the upper end of the feeding cylinder 6 is provided with a feed inlet 66, and multiple feed inlets 66 are arranged around the periphery of the feeding cylinder 6. When the concentration of pollutants in the gas to be adsorbed is low, the linear actuator 1 64 drives the feeding cylinder 6 to move downward, so that the feed inlet 66 on the feeding cylinder 6 connects with the discharge outlet 2 32 on the rotating drum 3. The linear actuator 2 17 drives the storage cylinder 2 to move upward, and the activated carbon in the storage cylinder 2 enters the feeding cylinder 6 sequentially through the discharge outlet 2 32 and the feed inlet 66, replenishing activated carbon as needed and reducing the unnecessary consumption of fresh activated carbon.

[0074] like Figure 4 and Figure 5 As shown, the cover plate 61, the cylinder wall of the feeding cylinder 6, and the bottom plate 21 are all provided with vent holes 23. The gas to be adsorbed can enter the storage cylinder 2 through the vent holes 23 on the bottom plate 21, be adsorbed by the activated carbon, and then be discharged upward through the vent holes 23 on the cylinder wall of the feeding cylinder 6 and the vent holes 23 on the cover plate 61 in sequence.

[0075] The implementation principle of an activated carbon adsorption tower for chemical product processing in this embodiment is as follows:

[0076] Both the storage cylinder 2 and the feed cylinder 6 contain activated carbon. When the concentration of pollutants in the gas to be adsorbed is high, the linear actuator 64 drives the feed cylinder 6 to move upward, and the discharge port 65 connects with the discharge port 32, allowing the activated carbon in the feed cylinder 6 to enter the storage cylinder 2.

[0077] If the concentration of pollutants in the gas to be adsorbed is low, the linear actuator 64 drives the feeding cylinder 6 to move downward, so that the inlet 66 on the feeding cylinder 6 is connected to the outlet 32 ​​on the rotating drum 3. The linear actuator 17 drives the storage cylinder 2 to move upward, and the activated carbon in the storage cylinder 2 enters the feeding cylinder 6 in sequence through the outlet 32 ​​and the inlet 66.

[0078] The gas to be adsorbed enters the tower body 1 through the air inlet 11. Guided by the two spiral plates 4, part of the gas flows from the lower end of the spiral plate 4 along the rotation path of the spiral plate 4, and then enters the storage cylinder 2 from the upper end of the spiral plate 4. The other part of the gas passes directly through the spiral plate 4 through the gas distribution hole 42 and enters the storage cylinder 2, where it is adsorbed by the activated carbon in the storage cylinder 2.

[0079] The gas to be adsorbed flows through two paths, spiral and vertical, forming a composite airflow pattern of mainstream rotation and perforated diversion. This is beneficial for increasing gas dispersion and also for separating particulate impurities from the gas. The sponge layer 41 on the spiral plate 4 adsorbs particulate impurities.

[0080] When the sponge layer 41 needs cleaning, the drive assembly 5 drives the rotating drum 3 to rotate forward. The rotating drum 3 drives the spiral plate 4 to rotate. Since the cleaning frame 14 and the inner wall of the tower body 1 are slidably connected, one end of the cleaning rod 15 is connected to the cleaning frame 14, and the other end of the cleaning rod 15 is slidably connected to the spiral groove 31. When the spiral plate 4 rotates, it drives the cleaning rod 15 to move downward spirally through the threaded engagement with the cleaning rod 15. The two cleaning rods 15 squeeze the sponge layer 41, squeezing out the accumulated particulate impurities from the sponge layer 41. As the cleaning rod 15 continues to spiral downward, it gradually squeezes out the particulate impurities in the sponge layer 41 and they fall to the bottom of the tower body 1. When the cleaning rod 15 reaches the lower end of the spiral plate 4, the drive assembly 5 drives the rotating drum 3 to rotate in the opposite direction, causing the cleaning rod 15 to move upward and gradually move to the upper end of the spiral plate 4.

[0081] After being adsorbed by activated carbon, the gas rises. The demister 12 intercepts any tiny droplets that may be carried in the gas. The gas treated by the demister 12 is then discharged from the outlet 13.

[0082] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
