Description

Technical Field

[0001] This utility model relates to the field of activated carbon regeneration technology, and in particular to an activated carbon regeneration device. Background Technology

[0002] Activated carbon, as an adsorbent material with high specific surface area and well-developed pore structure, is widely used in chemical, pharmaceutical, and environmental fields. With the large-scale use of activated carbon, if saturated activated carbon cannot be effectively regenerated, it will not only waste resources but may also cause secondary pollution due to landfill or incineration. Therefore, activated carbon regeneration technology is of great significance for reducing industrial costs and achieving resource recycling.

[0003] Microwave regeneration technology has become one of the mainstream technologies for activated carbon regeneration due to its advantages such as fast heating speed, low energy consumption, and high regeneration efficiency. Existing microwave regeneration devices mostly adopt continuous conveying structures (such as auger conveyors), using microwave radiation to heat and desorb pollutants adsorbed on the activated carbon, while simultaneously introducing inert gas to protect the activated carbon from oxidation. However, there is still room for optimization in practical applications: for example, material accumulation during conveying can lead to uneven microwave field distribution, resulting in insufficient heating of some activated carbon particles and affecting the regeneration effect; the contact efficiency between the inert gas and the material is also limited by a single flow direction, making it difficult to fully carry away the desorbed pollutants, resulting in low mass transfer efficiency.

[0004] In existing continuous microwave regeneration devices, the relative motion between the material and the equipment components is limited (mostly unidirectional translation or rotation), resulting in insufficient tumbling frequency of activated carbon particles within the microwave enclosure. This easily leads to localized overheating or incomplete regeneration. Simultaneously, the fixed connection between the gas distribution structure and the enclosure prevents the inert gas from fully contacting the counter-moving material, further hindering the improvement of desorption efficiency. These problems ultimately result in significant fluctuations in activated carbon regeneration efficiency and poor consistency in the adsorption performance of the regenerated product, making it difficult to meet the demands of large-scale industrial applications. Utility Model Content

[0005] To address the problems of large fluctuations in activated carbon regeneration efficiency and poor consistency in the adsorption performance of regenerated products, which make it difficult to meet the needs of large-scale industrial applications, this utility model provides an activated carbon regeneration device.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0007] An activated carbon regeneration device includes a base, a microwave housing rotatably disposed in the center of the base, a hollow distributor rotatably disposed in the center of the base, the distributor including a hollow disc, an air inlet pipe connected to the center of the bottom surface of the disc, the air inlet pipe passing through the base and connected to a rotary joint, an exhaust pipe and a feed pipe disposed on the top surface of the microwave housing, a discharge pipe disposed on the lower outer wall of the microwave housing, and a rotary drive mechanism connected to the microwave housing and the distributor, the rotary drive mechanism being used to drive the microwave housing and the distributor to rotate simultaneously and in opposite directions. This activated carbon regeneration device employs a design that simultaneously reverses the rotation of the microwave housing and the distributor. On one hand, the relative motion between the two significantly increases the frequency and uniformity of the activated carbon material's movement within the housing, avoiding uneven microwave heating caused by localized accumulation and ensuring that the activated carbon particles are heated sufficiently and consistently. On the other hand, the reverse rotation, combined with the gas distribution function of the distributor's disc, enables inert gas to form efficient reverse contact with the material, significantly enhancing gas-solid mass transfer efficiency. This allows for more thorough removal of desorbed pollutants, effectively solving the problems of incomplete activated carbon regeneration, large efficiency fluctuations, and poor product performance consistency in existing technologies. Ultimately, this improves the regeneration quality and stability of activated carbon, making it more suitable for large-scale industrial applications.

[0008] Preferably, a stirring shaft is fixedly installed in the center of the top surface of the disk. This fixed stirring shaft, located in the center of the top surface of the disk, further enhances the disturbance effect on the activated carbon material, building upon the counter-rotation of the microwave housing and the distributor. When the stirring shaft rotates synchronously with the distributor, it penetrates deep into the material to create longitudinal stirring, breaking up the layered accumulation of material within the housing. This ensures that activated carbon particles at different depths are fully exposed to the microwave field, preventing localized insufficient heating due to material stratification. Simultaneously, the mechanical disturbance of the stirring shaft helps disperse agglomerated activated carbon particles, increasing their contact area with the inert gas. Combined with the overall counter-rotation trend, this further improves the uniformity of microwave heating and gas mass transfer efficiency, reducing the phenomenon of incomplete activated carbon regeneration.

[0009] Preferably, a spiral blade is fixedly mounted on the outer wall of the stirring shaft; a spiral blade is mounted on the inner wall of the microwave housing. The spiral blade on the outer wall of the stirring shaft and the spiral blade on the inner wall of the microwave housing cooperate with each other. When the microwave housing and the distributor rotate in opposite directions, the reverse spiral structure of the blades creates a bidirectional shearing and pushing effect on the activated carbon material: when the spiral blade rotates with the stirring shaft, it can lift the material at the bottom upwards, while when the spiral blade rotates in opposite directions with the microwave housing, it generates a downward guiding force on the material. The interaction between the two causes the activated carbon particles to be continuously cut and turned in the longitudinal movement, greatly reducing agglomeration and ensuring that each particle can be uniformly contacted by the microwave field. At the same time, this bidirectional spiral structure can also extend the residence time of the material in the housing. Combined with the lateral disturbance brought by the reverse rotation, it allows the inert gas to have more time to contact the material and fully carry away the desorbed pollutants. This further improves the heating uniformity and mass transfer efficiency based on the stirring shaft, effectively avoiding the problem of incomplete local regeneration.

[0010] Preferably, the outer diameter of the first helical blade gradually decreases from bottom to top. This structure, with its gradually decreasing outer diameter, creates a suitable longitudinal spatial gradient with the second helical blade on the inner wall of the microwave housing. The larger outer diameter of the blade at the bottom provides a stronger upward pushing force on the accumulated activated carbon material, preventing material accumulation at the bottom. The gradually decreasing outer diameter at the top reduces excessive disturbance to the already dispersed material, allowing it to gradually loosen and disperse during its ascent, reducing the probability of particle collision and agglomeration. Simultaneously, this gradual structure, combined with the counter-rotating microwave housing, creates an alternating "compression-loosening" space from bottom to top within the housing. This facilitates smoother penetration of inert gas through the material layer, improving gas-solid contact efficiency at different heights, further optimizing the uniformity of microwave heating and the desorption effect of pollutants, ensuring that the activated carbon can be fully regenerated from bottom to top.

[0011] Preferably, two material-pushing plates are fixedly installed on the inner wall of the microwave shell, and the material-pushing plates are positioned between the spiral blades and the disk; the included angle between the two material-pushing plates is 180°. The two material-pushing plates, symmetrically distributed at 180° on the inner wall of the microwave shell and located between the spiral blades and the disk, can create targeted disturbance to the material at the bottom when the microwave shell rotates in the reverse direction: when the microwave shell rotates, the material-pushing plates move synchronously with it, lifting the activated carbon material accumulated on the top of the disk upwards and dispersing it to both sides, preventing the material from stagnating or forming dead zones in the gap between the spiral blades and the disk. Combined with inert gas, this ensures that the material at the bottom enters the effective range of the spiral blades in a timely manner. Simultaneously, the 180° symmetrical design makes the force on the material within the shell more even, and the bidirectional pushing action of the spiral blades further enhances the overall fluidity and turning frequency of the material, reducing uneven heating caused by localized accumulation and ensuring the stability of the regeneration effect.

[0012] Preferably, the disc body has several arc-shaped blades evenly arranged along the circumference; the top surface of the disc body has several jet holes. The evenly arranged arc-shaped blades, when the distributor rotates, guide and pressurize the inert gas entering the disc body, ensuring a uniform circumferential distribution of the gas and its exit through the jet holes on the top surface, avoiding airflow concentration caused by a single jet hole. The even arrangement of the jet holes, combined with the guiding effect of the arc-shaped blades, allows the inert gas to penetrate into the activated carbon material layer at a more uniform rate and pressure, forming efficient gas-solid contact with the counter-rotating microwave shell and the material, fully carrying away desorbed pollutants. Simultaneously, the centrifugal force generated by the rotation of the arc-shaped blades enhances the penetrating power of the gas jet, ensuring the gas reaches deep into the material, solving the problem of insufficient gas supply to deep materials using traditional fixed jet holes. This improves gas-solid mass transfer efficiency while further ensuring the uniformity of activated carbon regeneration.

[0013] Preferably, the rotary drive mechanism includes a motor; the motor is fixedly mounted on a bracket; the motor is connected to the outer wall of the microwave housing via a gear transmission assembly; the motor is connected to the outer wall of the air inlet pipe via a synchronous belt transmission assembly. The rotary drive mechanism employs a design where a single motor is connected to both the microwave housing and the air inlet pipe via gear and synchronous belt transmission assemblies respectively. This design enables both the reverse rotation of the microwave housing and the distributor, while ensuring coordinated movement of both through a single power source, avoiding speed matching errors caused by multiple motor drives. The gear transmission assembly transmits high torque, suitable for driving the stable rotation of the microwave housing, while the synchronous belt transmission assembly features smooth transmission and low noise, adapting to the high-speed rotation requirements of the air inlet pipe. The combination of these two transmission methods satisfies the motion characteristics of different components, simplifies the overall structure, and reduces the assembly complexity and maintenance costs of the equipment.

[0014] Preferably, the gear transmission assembly includes a driving gear keyed to the output shaft of the motor; the driving gear meshes with a driven gear; and the driven gear is keyed to the outer wall of the microwave housing.

[0015] Preferably, the motor output shaft is connected to the drive shaft via a coupling; the synchronous belt drive assembly includes a drive pulley keyed to the drive shaft; the drive pulley is connected to the driven pulley via a synchronous belt; and the driven pulley is keyed to the air intake pipe.

[0016] Preferably, support legs are fixedly installed at the corners of the base bottom surface; a rotary joint two is connected to the exhaust pipe. The rotary joint two connected to the exhaust pipe can ensure stable connection between the exhaust pipe and the external exhaust gas treatment pipeline during the rotation of the microwave shell. This does not affect the reverse rotation of the microwave shell, and also prevents gas leakage, ensuring the stability of the inert gas atmosphere inside the microwave shell and the orderly discharge of exhaust gas. The combination of these two features further improves the structural stability and operational reliability of the device, providing a guarantee for the continuous and efficient operation of the activated carbon regeneration process.

[0017] The beneficial effects of this utility model are:

[0018] This activated carbon regeneration device employs a design that simultaneously reverses the rotation of the microwave housing and the distributor. On one hand, the relative motion between the two significantly increases the frequency and uniformity of the activated carbon material's movement within the housing, avoiding uneven microwave heating caused by localized accumulation and ensuring that the activated carbon particles are heated sufficiently and consistently. On the other hand, the reverse rotation, combined with the gas distribution function of the distributor's disc, enables inert gas to form efficient reverse contact with the material, significantly enhancing gas-solid mass transfer efficiency.

Ultimately, this improves the regeneration quality and stability of activated carbon, making it more suitable for large-scale industrial applications. Attached Figure Description

[0026] The present invention will now be described and explained in detail with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1 , Figure 2 and Figure 3As shown, an activated carbon regeneration device includes a base 1, a microwave housing 2 rotatably mounted in the center of the base 1, and a hollow distributor 3 rotatably mounted in the center of the base 1. The distributor 3 includes a hollow disc 301; an air inlet pipe 302 is connected to the center of the bottom surface of the disc 301; the air inlet pipe 302 passes through the base 1 and is connected to a rotary joint 4; an exhaust pipe 201 and a feed pipe 202 are provided on the top surface of the microwave housing 2; a discharge pipe 203 is provided on the lower outer wall of the microwave housing 2; a rotary drive mechanism is connected to the microwave housing 2 and the distributor 3; the rotary drive mechanism is used to drive the microwave housing 2 and the distributor 3 to rotate simultaneously and in opposite directions. Support legs 101 are fixedly mounted at the corners of the bottom surface of the base 1; a rotary joint 14 is connected to the exhaust pipe 201.

[0029] This activated carbon regeneration device employs a design that simultaneously reverses the rotation of the microwave housing 2 and the distributor 3. On one hand, the relative motion between the two significantly increases the frequency and uniformity of the activated carbon material's movement within the housing, avoiding uneven microwave heating caused by localized accumulation and ensuring that the activated carbon particles are heated sufficiently and consistently. On the other hand, the reverse rotation, combined with the gas distribution function of the distributor 3's disc 301, enables inert gas to form efficient reverse contact with the material, significantly enhancing gas-solid mass transfer efficiency. This allows for more thorough removal of desorbed pollutants, effectively solving the problems of incomplete activated carbon regeneration, large efficiency fluctuations, and poor product performance consistency in existing technologies. Ultimately, this improves the regeneration quality and stability of activated carbon, making it more suitable for large-scale industrial applications. The rotary joint 14 connected to the exhaust pipe 201 ensures stable connection between the exhaust pipe 201 and the external exhaust gas treatment pipeline during the rotation of the microwave housing 2. This does not affect the reverse rotation of the microwave housing 2, and also prevents gas leakage, ensuring the stability of the inert gas atmosphere inside the microwave housing 2 and the orderly discharge of exhaust gas. The combination of these two features further enhances the structural stability and operational reliability of the device, providing a guarantee for the continuous and efficient operation of the activated carbon regeneration process.

[0030] In the above configuration, the rotary drive mechanism includes a motor 5; the motor 5 is fixedly mounted on the bracket 6; the motor 5 is connected to the outer wall of the microwave housing 2 via a gear transmission assembly; the motor 5 is connected to the outer wall of the air inlet pipe 302 via a synchronous belt transmission assembly. The gear transmission assembly includes a driving gear 7 keyed to the output shaft of the motor 5; the driving gear 7 meshes with a driven gear 8; the driven gear 8 is keyed to the outer wall of the microwave housing 2. The output shaft of the motor 5 is connected to a transmission shaft 10 via a coupling 9; the synchronous belt transmission assembly includes a driving pulley 11 keyed to the transmission shaft 10; the driving pulley 11 is connected to a driven pulley 13 via a synchronous belt 12; the driven pulley 13 is keyed to the air inlet pipe 302.

[0031] The rotary drive mechanism adopts a design in which a single motor 5 is connected to the microwave housing 2 and the air inlet pipe 302 respectively through a gear transmission assembly and a synchronous belt 12 transmission assembly. This design can realize the reverse rotation of the microwave housing 2 and the distributor 3, and can also ensure the coordination of their movements through the same power source, avoiding speed matching errors caused by multiple motors 5 driving. The gear transmission assembly transmits large torque and is suitable for driving the stable rotation of the microwave housing 2, while the synchronous belt 12 transmission assembly has the characteristics of smooth transmission and low noise, which is suitable for the high-speed rotation requirements of the air inlet pipe 302. The combination of the two transmission methods not only meets the motion characteristics of different components, but also simplifies the overall structure and reduces the assembly complexity and maintenance cost of the equipment.

[0032] like Figure 4 and Figure 5 As shown, a stirring shaft 303 is fixedly installed in the middle of the top surface of the disk 301. A first spiral blade 304 is fixedly installed on the outer wall of the stirring shaft 303; a second spiral blade 204 is installed on the inner wall of the microwave housing 2. The outer diameter of the first spiral blade 304 gradually decreases from bottom to top.

[0033] A fixed stirring shaft 303 is installed in the middle of the top surface of the disk 301. Based on the counter-rotation of the microwave housing 2 and the distributor 3, it can further enhance the disturbance effect on the activated carbon material. When the stirring shaft 303 rotates synchronously with the distributor 3, it can penetrate deep into the material to form longitudinal stirring, break the layered accumulation of the material in the housing, and ensure that activated carbon particles at different depths can be fully exposed to the microwave field, avoiding insufficient local heating caused by material stratification. At the same time, the mechanical disturbance of the stirring shaft 303 can also help disperse the agglomerated activated carbon particles, increase their contact area with the inert gas, and, in conjunction with the overall movement trend of counter-rotation, further improve the uniformity of microwave heating and gas mass transfer efficiency, and reduce the phenomenon of incomplete activated carbon regeneration. The spiral blades 304 on the outer wall of the stirring shaft 303 and the spiral blades 204 on the inner wall of the microwave housing 2 work together. When the microwave housing 2 and the distributor 3 rotate in opposite directions, the reverse spiral structure of the blades creates a bidirectional shearing and pushing effect on the activated carbon material: when the spiral blades 304 rotate with the stirring shaft 303, they can lift the material at the bottom upwards, while when the spiral blades 204 rotate in the opposite direction with the microwave housing 2, they generate a downward guiding force on the material. The interaction between the two causes the activated carbon particles to be continuously cut and turned in the longitudinal movement, greatly reducing agglomeration and ensuring that each particle can be uniformly contacted by the microwave field. At the same time, this bidirectional spiral structure can also extend the residence time of the material in the housing. Combined with the lateral disturbance brought by the reverse rotation, it allows the inert gas to have more time to contact the material and fully carry away the desorbed pollutants. This further improves the heating uniformity and mass transfer efficiency on the basis of the stirring shaft 303, effectively avoiding the problem of incomplete local regeneration. The spiral blade 304 adopts a structure with a gradually decreasing outer diameter from bottom to top, which can form a suitable longitudinal spatial gradient with the spiral blade 204 on the inner wall of the microwave housing 2: the larger outer diameter blade at the bottom can generate a stronger upward pushing force on the accumulated activated carbon material, avoiding the accumulation of material at the bottom, while the gradually decreasing outer diameter at the top can reduce excessive disturbance to the already dispersed material, so that the material gradually loosens and disperses during the ascent, reducing the probability of collision and agglomeration between particles; at the same time, this gradient structure can also work with the counter-rotating microwave housing 2 to form an alternating "compression-loosening" space from bottom to top in the housing, which promotes the smoother penetration of inert gas into the material layer, improves the gas-solid contact efficiency in different height areas, further optimizes the uniformity of microwave heating and the desorption effect of pollutants, and ensures that the activated carbon can be fully regenerated from the bottom to the top.

[0034] Two material-pushing plates 205 are fixedly installed on the inner wall of the microwave housing 2, and the material-pushing plates 205 are positioned between the spiral blades 204 and the disk body 301; the included angle between the two material-pushing plates 205 is 180°. Several arc blades 305 are evenly arranged along the circumferential direction inside the disk body 301; several air jet holes 306 are provided on the top surface of the disk body 301.

[0035] Two symmetrically arranged material-pushing plates 205, positioned at 180°, are installed on the inner wall of the microwave housing 2, between the spiral blade 204 and the disk 301. These plates can create targeted disturbance to the material at the bottom when the microwave housing 2 rotates in the reverse direction. As the microwave housing 2 rotates, the material-pushing plates 205 move synchronously, lifting the activated carbon material accumulated on the top of the disk 301 upwards and dispersing it to both sides. This prevents material from stagnating or forming dead zones in the gap between the spiral blade 204 and the disk 301. Combined with inert gas, this ensures that the material at the bottom enters the effective range of the spiral blades in a timely manner. Simultaneously, the 180° symmetrical design makes the force on the material within the housing more even. Combined with the bidirectional pushing action of the spiral blades 304 and 204, this further enhances the overall fluidity and turning frequency of the material, reducing uneven heating caused by localized accumulation and ensuring the stability of the regeneration effect. The arc blades 305, evenly arranged along the circumference inside the disc 301, guide and pressurize the inert gas entering the disc 301 when the distributor 3 rotates. This ensures the gas is evenly distributed along the circumference and ejected through several jet holes 306 on the top surface of the disc 301, avoiding the airflow concentration caused by jetting from a single hole. The even arrangement of the jet holes 306, combined with the guiding effect of the arc blades 305, allows the inert gas to penetrate into the activated carbon material layer at a more uniform rate and pressure, forming efficient gas-solid contact with the counter-rotating microwave shell 2 and the material, fully carrying away the desorbed pollutants. At the same time, the centrifugal force generated by the arc blades 305 rotating with the distributor 3 enhances the penetration of the gas jet, ensuring that the gas can penetrate deep into the material, solving the problem of insufficient gas supply to deep materials by traditional fixed jet holes 306. This improves the gas-solid mass transfer efficiency and further ensures the uniformity of activated carbon regeneration.
