Description

Technical Field

[0001] This invention relates to the field of activated carbon regeneration technology, and in particular to an activated carbon thermal cycle regeneration device and process. Background Technology

[0002] Activated carbon is widely used in waste gas treatment, sewage treatment, solvent recovery and other fields. Expired activated carbon can have its adsorption performance restored by thermal regeneration. In the existing activated carbon thermal cycle regeneration process, vertical continuous thermal regeneration furnace equipment is often used. It has become the mainstream equipment due to its advantages such as small footprint, high thermal efficiency and continuous operation. The equipment is mainly composed of a preheating section, a regeneration section and a cooling section from top to bottom. Expired activated carbon passes through each functional section in sequence by gravity. In the preheating section, it is initially heated by the waste heat of high temperature flue gas or high temperature steam generated in the lower regeneration section. Then it enters the regeneration section to complete desorption and regeneration. Finally, it is discharged through the cooling section. The preheating effect of the preheating section directly affects the regeneration energy consumption and product quality.

[0003] Existing vertical continuous thermal regeneration furnaces typically employ a straight-through cylindrical structure for the preheating section, with multiple sets of inclined baffles inside. Activated carbon falls along these baffles in a zigzag pattern, exchanging heat counter-currently with rising flue gas or steam. However, this structure still suffers from several shortcomings. First, the carbon residence time is too short, resulting in insufficient preheating. This is because the structure relies on gravity for descent and lacks a delay mechanism, while activated carbon has a low thermal conductivity, requiring a considerable amount of time for heat to reach the particle core. Second, fixed baffles easily cause particle accumulation and flow dead zones, leading to uneven preheating temperatures. This is because the irregular and unevenly sized carbon particles tend to stagnate at the connection between the baffle and the cylinder wall, as well as at turning points, disrupting flow uniformity. Finally, the gas-solid flow matching is poor, resulting in low heat exchange efficiency. This is because uneven carbon flow makes it easy for flue gas and steam to short-circuit through sparse areas, reducing waste heat utilization. Therefore, how to extend the residence time and avoid accumulation and dead zones while controlling the equipment height is a pressing technical problem that needs to be solved in this field. Thus, this application provides an activated carbon thermal circulation regeneration device and its process to meet these needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an activated carbon thermal circulation regeneration equipment and process to solve the problems of short residence time, easy accumulation of dead zones, and low heat exchange efficiency in the preheating section of the existing vertical continuous thermal regeneration furnace.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An activated carbon thermal circulation regeneration device includes an input area, a preheating chamber, a regeneration chamber, and a cooling output area arranged from top to bottom. The input area, preheating chamber, regeneration chamber, and cooling output area are externally supported and fixed by brackets. A uniformly distributed guide plate is fixedly connected to the inner wall of the preheating chamber. The guide plate is inclined inside the preheating chamber, and a baffle is fixedly connected to the top of the guide plate. Mounting seats are arranged in an array on the guide plate. A movable plate is rotatably connected to the mounting seat via a rotating rod, and the mounting seat has a movable cavity for accommodating the rotating rod and the movable plate. A locking assembly is fixedly connected to the outside of the mounting seat. The locking assembly is used to fix the relative position between the guide plate and the mounting seat. The locking assembly includes a clamping plate fixedly connected to the outside of the mounting seat. A limiting assembly is provided inside the mounting seat to limit the position of the movable plate in the mounting seat. The limiting assembly includes a protruding area on the top of the side of the mounting seat away from the clamping plate. A cavity is formed in the protruding area, and a movable seat that can slide up and down is fitted in the cavity. A limiting plate is fixedly connected to the bottom of the movable seat.

[0006] Optionally, a discharge area is provided on the inner top of the preheating chamber, and a discharge pipe connected to the discharge area is fixedly connected to the outside of the preheating chamber, with a control valve provided on the outside of the discharge pipe.

[0007] Optionally, the baffle is in the shape of a convex disc, and the edge of the baffle is provided with a fixed edge that is fixedly connected to the top of the guide plate. The baffle has evenly distributed through holes.

[0008] Optionally, the card plate and the mounting base are parallel to each other, and an S-shaped deformation zone is provided at the connection between the card plate and the mounting base.

[0009] Optionally, a hook plate is fixedly connected to the end of the pallet near the mounting base, and a handle is fixedly connected to the end of the pallet away from the mounting base.

[0010] Optionally, the mounting base has a positioning groove on the side near the card plate that matches the shape of the hook plate, and the guide plate has a through opening that matches the size of the hook plate and the positioning groove.

[0011] Optionally, a guide surface is provided at one end of the card plate near the hook plate, and there is a gap between the mounting base and the card plate that matches the thickness of the guide plate, and the mounting base and the card plate are parallel to each other.

[0012] Optionally, a uniformly distributed spring is fixedly connected between the movable seat and the protruding area, the bottom end of the limiting plate extends into the movable cavity, and a limiting strip corresponding to the bottom end position of the limiting plate is fixedly connected to the outside of the rotating rod.

[0013] A regeneration process for an activated carbon thermal cycle regeneration device includes the following steps: S1. Feeding and preheating drying: The saturated activated carbon to be regenerated enters the preheating chamber from the top input area. After being dispersed by the baffle, it passes through the guide plate and the movable plate, increasing the residence time of the saturated activated carbon. It is heated by the countercurrent high-temperature medium in the regeneration chamber to remove moisture and low-boiling-point organic matter, thus completing the drying and preliminary preheating. S2, the core stage of high-temperature thermal regeneration: the preheated activated carbon enters the regeneration chamber in the middle, and in a low-oxygen environment of 600℃ to 900℃, it sequentially completes the desorption of organic matter, pyrolysis and carbonization and micropore activation, restores adsorption performance and completes the regeneration reaction. S3. Cooling and safety protection: The regenerated activated carbon continues to fall into the lower cooling output zone, where it is rapidly cooled to a safe temperature by water cooling. S4. Sealed discharge and circulation: The cooled activated carbon is discharged through a sealed unloading device connected to the cooling output area at the bottom and directly transported back to the adsorption system. The waste gas generated during the regeneration process is discharged through the discharge area, discharge pipe and control valve at the top of the preheating chamber.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up an input area, a preheating chamber, a regeneration chamber, and a cooling output area that are connected sequentially from top to bottom, and fixing evenly distributed inclined guide plates and protruding disc-shaped baffles on the inner wall of the preheating chamber, and with the through-holes on the baffles, the saturated activated carbon is evenly dispersed by the baffles and falls step by step along the channel formed by the guide plates after being put in, which prolongs the residence time of the activated carbon in the preheating chamber and realizes the full preheating and orderly transportation of the activated carbon in the preheating chamber.

[0015] By designing a swing mechanism consisting of a mounting base, a rotating rod, and a movable plate, and setting a limiting component inside the mounting base consisting of a movable seat, a spring, a limiting plate, and an upper limit bar on the rotating rod, when a countercurrent airflow is generated in the regeneration chamber, the movable plate can swing back and forth around the rotating rod, continuously lifting the activated carbon that falls on it, thus preventing material accumulation. At the same time, the limiting component uses the spring force to push the limiting plate and the limiting bar to cooperate, so that the movable plate can quickly return to its original position after swinging, ensuring that the activated carbon is evenly dispersed and efficiently preheated in the preheating chamber.

[0016] By setting a clamping plate, hook plate, and handle with a deformation zone on the outside of the mounting base, and opening a through-hole on the guide plate, the mounting base and clamping plate are simply inserted into the sides of the guide plate during installation. The elasticity of the deformation zone allows the hook plate to pass through the through-hole and lock into the positioning groove, thus achieving quick locking. During disassembly, the handle is turned to remove the hook plate, realizing tool-free quick assembly and disassembly of the mounting base on the guide plate, which greatly facilitates the inspection and maintenance of the preheating chamber.

[0017] By fixing the fixed edge of the baffle to the top of the guide plate, the baffle is made into a convex disc shape with evenly distributed round holes. This ensures the initial dispersion effect of saturated activated carbon when it enters the preheating chamber and avoids blockage of activated carbon at the beginning of the guide plate. At the same time, the limiting component in the mounting base blocks the entrance of the moving chamber to prevent activated carbon particles from entering and affecting the working environment of the rotating rod, thereby further improving the stability and service life of the equipment.

[0027] like Figures 1 to 12As shown, an embodiment of the present invention provides an activated carbon thermal circulation regeneration device, including an input area 1, a preheating chamber 2, a regeneration chamber 3, and a cooling output area 4 arranged from top to bottom. The input area 1, preheating chamber 2, regeneration chamber 3, and cooling output area 4 are externally supported and fixed by a bracket 5. A uniformly distributed guide plate 7 is fixedly connected to the inner wall of the preheating chamber 2. The guide plate 7 is inclined inside the preheating chamber 2, and a baffle 6 is fixedly connected to the top of the guide plate 7. The baffle 6 is generally convex in the shape of a disc, and a fixing edge 11 is provided at the edge of the baffle 6 that is fixedly connected to the top of the guide plate 7. The baffle 6 has uniformly distributed through holes 12. An array of [missing information] is distributed on the guide plate 7. Mounting base 14, with a movable plate 15 rotatably connected to it via a rotating rod 26. Mounting base 14 also has a movable cavity 25 for accommodating the rotating rod 26 and the movable plate 15. A locking assembly is fixedly connected to the outside of mounting base 14 to fix the relative position between the guide plate 7 and mounting base 14. A limit assembly is provided inside mounting base 14 to limit the position of the movable plate 15 within it. Input area 1 is used for feeding saturated activated carbon. Input area 1 is generally inclined and pipe-shaped, facilitating the transfer and feeding of saturated activated carbon between it and other conveying mechanisms. Input area 1 is equipped with a closed door; when saturated activated carbon is fed, the closed door opens, allowing the input... During thermal regeneration, the sealed door is closed to prevent the waste gas generated during regeneration from being directly discharged through the input zone 1. The preheating chamber 2 is the preheating area for saturated activated carbon. The guide plate 7 and movable plate 15 in the preheating chamber 2 can increase the residence time of saturated activated carbon in the preheating chamber 2, thus fully preheating the saturated activated carbon. At the same time, since the movable plate 15 is rotatably connected to the mounting base 14 through the rotating rod 26, the movable plate 15 can also swing around the rotating rod 26 under the action of the countercurrent airflow in the regeneration chamber 3, lifting the saturated activated carbon falling on the movable plate 15 and preventing the saturated activated carbon from generating waste gas during the process of passing through the guide plate 7 and the movable plate 15. Accumulation of activated carbon can affect its preheating effect. The regeneration chamber 3 is the reaction zone for activated carbon regeneration, which can generate a low-oxygen environment of 600°C to 900°C for thermal cycle regeneration of saturated activated carbon. The middle part of the cooling output zone 4 is the cooling area, and the bottom end is the output pipe connected to the sealed unloading device. The activated carbon can be quickly cooled to a safe temperature by water cooling in the middle, and the cooled activated carbon is discharged through the sealed unloading device connected to the cooling output zone 4. The principle and working process of the above-mentioned input zone 1, regeneration chamber 3 and cooling output zone 4 are the same as those of the existing technology, and will not be described in detail here. The support 5 is used to support and fix the entire equipment to ensure the stability of the overall operation of the equipment.

[0028] In this embodiment, as Figures 2 to 4As shown, the baffle 6 disperses the saturated activated carbon entering the preheating chamber 2, allowing it to fall along the channel formed by the guide plate 7, ensuring the saturated activated carbon's falling path in the preheating chamber 2. The mounting base 14 is installed on the guide plate 7 via a locking component, enabling quick assembly and disassembly, and ensuring stability after installation. This facilitates the later inspection and maintenance of the preheating chamber 2. The limiting component in the mounting base 14 can, on the one hand, block the entrance of the movable cavity 25 on the mounting base 14, preventing activated carbon particles from entering the mounting base 14 and affecting the working environment of the movable plate 15. On the other hand, it can also limit the relative position between the movable plate 15 and the mounting base 14, maintaining the angle between the movable plate 15 and the guide plate 7, allowing the movable plate 15 to quickly reset after swinging, thereby continuously realizing the swinging action of the movable plate 15, preventing the accumulation of saturated activated carbon, and further ensuring the preheating effect in the preheating chamber 2.

[0029] The preheating chamber 2 has a discharge zone 8 on its inner top, and a discharge pipe 9 connected to the discharge zone 8 is fixedly connected to the outside of the preheating chamber 2. A control valve 10 is installed on the outside of the discharge pipe 9. The bottom of the discharge zone 8 has evenly distributed passage openings. When the saturated activated carbon is regenerated in the regeneration chamber 3 through thermal cycling, a certain amount of waste gas will be generated during the regeneration process. The waste gas generated can be discharged through the discharge zone 8 on the top of the preheating chamber 2, the discharge pipe 9 and the control valve 10. After treatment, it will be discharged to avoid causing environmental pollution.

[0030] In this embodiment, as Figures 5 to 10As shown, the locking assembly includes a locking plate 16 fixedly connected to the outside of the mounting base 14. The locking plate 16 and the mounting base 14 are parallel to each other, and an S-shaped deformation zone 17 is provided at the connection position between the locking plate 16 and the mounting base 14. A hook plate 22 is fixedly connected to the end of the locking plate 16 near the mounting base 14, and a handle 24 is fixedly connected to the end of the locking plate 16 away from the mounting base 14. A positioning groove 23 adapted to the shape of the hook plate 22 is formed on the side of the mounting base 14 near the locking plate 16. A guide plate 7 is provided with a groove 23 that matches the shape of the hook plate 22 and the positioning groove 24. A through opening 13 of size is provided to match the guide plate 7. A guide surface 21 is provided at one end of the clamping plate 16 near the hook plate 22. There is a gap between the mounting base 14 and the clamping plate 16 that matches the thickness of the guide plate 7, and the mounting base 14 and the clamping plate 16 are parallel to each other. This allows the whole formed by the mounting base 14 and the clamping plate 16 to be inserted from the outside of the guide plate 7, and the guide plate 7 is placed in the gap between the mounting base 14 and the clamping plate 16. The opening of the guide surface 21 makes the opening size of the gap at the end of the mounting base 14 and the clamping plate 16 larger, allowing the mounting base 14 to be inserted from the guide plate 7. The insertion operation outside the guide plate 7 is smoother. After the mounting base 14 and the clamping plate 16 are inserted into the outside of the guide plate 7, the hook plate 22 is squeezed by the outside of the guide plate 7, causing the clamping plate 16 to bend and deform at the deformation zone 17 until the hook plate 22 moves to the position corresponding to the through opening 13. At this time, pressing the end of the clamping plate 16 will allow the hook plate 22 to pass through the through opening 13 and enter the positioning groove 23 inside the mounting base 14, so that the hook plate 22 and the positioning groove 23 form a hook-and-fix relationship. The deformation zone 17 squeezes the clamping plate 16 and the hook plate with its own elasticity. 22. Maintaining the relative position between the hook plate 22 and the positioning groove 23 makes the installation operation of the mounting base 14 on the guide plate 7 simple and convenient, and stable and reliable after installation and fixing. The handle 24 is designed to facilitate the operation when disassembling the mounting base 14. When disassembling, the operator only needs to move the handle 24 to drive the locking plate 16 to deform again at the deformation area 17, and drive the hook plate 22 out of the positioning groove 23, releasing the locking state of the mounting base 14 on the guide plate 7. This makes the overall disassembly and replacement operation of the mounting base 14 simple and convenient, and easy for later maintenance.

[0031] In this embodiment, as Figures 7 to 12As shown, the limiting assembly includes a protruding area 18 on the top of the side of the mounting base 14 away from the card plate 16. A cavity is formed in the protruding area 18, and a movable seat 19 that can slide up and down is fitted inside the cavity. Evenly distributed springs 20 are fixedly connected between the movable seat 19 and the protruding area 18. A limiting plate 28 extending into the movable cavity 25 is fixedly connected to the bottom of the movable seat 19. A limiting strip 27 corresponding to the bottom position of the limiting plate 28 is fixedly connected to the outside of the rotating rod 26. The limiting assembly is used to limit the movable plate 15. Since the movable plate 15 is connected to the mounting base 14 by the rotation of the rotating rod 26, the movable plate 15 can swing. The movable plate 15 can be lifted by the airflow impact and then quickly reset under the action of the limiting component, thereby realizing the continuous swinging action of the movable plate 15. Specifically, the airflow flows from the bottom to the top of the movable plate 15, applying an upward force to the movable plate 15, allowing the movable plate 15 to deflect around the rotating rod 26 and be lifted. During this process, the rotation of the rotating rod 26 will synchronously drive the limiting strip 27 to deflect, and then the limiting strip 27 will squeeze the end of the limiting plate 28, causing the limiting plate 28 to drive the movable seat 19 to slide in the cavity inside the protrusion area 18. During the upward sliding process of the movable seat 19, it will press... The spring 20 is compressed, allowing it to accumulate elastic potential energy. When the airflow fluctuates, the accumulated elastic potential energy of the spring 20 is released, driving the movable seat 19 and the limiting plate 28 to press down, which in turn drives the rotating rod 26 and the movable plate 15 to reset. This process repeats, creating the swinging motion of the movable plate 15. At the same time, the limiting component also seals the gap near the upper end of the movable cavity 25 inside the mounting seat 14, preventing activated carbon particles from entering the movable cavity 25 and affecting the working environment of the rotating rod 26. This provides protection for the rotating rod 26 and improves the service life of the mounting seat 14 and the movable plate 15.

[0032] Embodiments of the present invention also provide an activated carbon thermal cycle regeneration process, comprising the following steps: S1. Feeding and Preheating Drying: The saturated activated carbon to be regenerated enters the preheating chamber 2 from the top input area 1. Under the combined action of gravity and the guide plate 7, mounting base 14 and movable plate 15 in the preheating chamber 2, it slowly moves downward. During this process, the saturated activated carbon first falls on the baffle plate 6, and after being dispersed by the baffle plate 6, it passes through the guide plate 7 and movable plate 15, increasing the residence time of the saturated activated carbon. It is heated by the countercurrent high-temperature flue gas or high-temperature steam in the regeneration chamber 3, removing moisture and low-boiling-point organic matter, thus completing the drying and preliminary preheating. The temperature range of the flue gas or steam here is 100°C to 180°C.

[0033] S2, the core stage of high-temperature thermal regeneration, the preheated activated carbon enters the regeneration chamber 3 in the middle, and in a low-oxygen environment of 600℃ to 900℃, it sequentially completes the desorption of organic matter, pyrolysis and carbonization and micropore activation, restores the adsorption performance and completes the regeneration reaction.

[0034] S3. Cooling and safety protection: The regenerated activated carbon continues to fall into the lower cooling output zone 4, where it is quickly cooled to a safe temperature by water cooling to prevent spontaneous combustion or re-adsorption of impurities when exposed to air at high temperatures.

[0035] S4. Sealed discharge and circulation: The cooled activated carbon is discharged through a sealed discharge device connected to the cooling output zone 4 at the bottom and directly transported back to the adsorption system. The waste gas generated during the regeneration process is discharged through the discharge zone 8 at the top of the preheating chamber 2, the discharge pipe 9 and the control valve 10, thus completing the thermal regeneration of the activated carbon.

Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0037] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
