Description

Technical Field

[0001] The invention relates to the technical field of activated carbon regeneration, in particular to an internal heating activated carbon regeneration furnace and a regeneration process. Background Art

[0002] The internal heating activated carbon regeneration furnace is a device used to restore the adsorption performance of deactivated activated carbon. The working principle is based on the thermal desorption process. By increasing the temperature in the furnace, various impurities and pollutants adsorbed on the surface and pores of the activated carbon are volatilized and decomposed due to heat. In this process, some heating systems will also introduce gases such as water vapor or carbon dioxide, which will react chemically with the activated carbon and adsorbents to assist in the desorption of the adsorbents and further improve the regeneration effect. Compared with other regeneration methods, the internal heating activated carbon regeneration furnace has significant advantages. It has high regeneration efficiency, can process a large amount of activated carbon in a relatively short time, and has relatively low energy consumption. Thanks to the good insulation structure and efficient heating system, the operating cost is reduced, and the physical structure of the activated carbon is less damaged, which can retain its original pore structure and adsorption performance to the greatest extent, thereby extending the service life of the activated carbon.

[0003] The deactivated activated carbon may contain residual metal impurities that affect the subsequent regeneration effect. The activated carbon is easily heated unevenly during the heating process, so we proposed an internal heating activated carbon regeneration furnace and regeneration process. Summary of the invention

[0005] The separation and collection device comprises an annular plate, the top of the annular plate is threadedly connected to a top cover, the bottom of the top cover is fixedly connected to an annular magnetic block, when there are too many metal impurities inside, the electric push rod releases the limit on the collection barrel, the collection barrel moves upward, and the annular magnetic block uses its own magnetism to adsorb the metal impurities in the collection barrel, so as to facilitate the cleaning of the metal impurities, a sleeve is arranged at the bottom center of the annular plate, the top of the inner wall of the sleeve is fixedly connected to a motor, the driving shaft of the motor is fixedly connected to a threaded rod, and the bottom of the motor is fixedly connected to a folding hose, when the collection barrel moves upward, the folding hose folds and contracts to prevent metal impurities from entering the threaded rod and avoid interfering with the rotation of the threaded rod, the bottom of the folding hose is fixedly connected to the collection barrel, and the collection barrel is used to temporarily store metal impurities scraped from the inner wall of the oblique screen barrel, To avoid impurities from scattering everywhere and facilitate subsequent centralized processing, circular grooves are provided on both sides of the bottom of the inner wall of the collecting cylinder, and an electric push rod is provided on the inner wall of the circular groove. The bottom of the threaded rod is fixedly connected to a fine rotating rod, and an inclined cylinder is sleeved and rotatably connected on the fine rotating rod. An inclined scraper is fixedly connected to the side of the inclined cylinder. The inclined scraper scrapes up the metal impurities remaining on the inner wall of the inclined screen cylinder, and makes the metal impurities move inward and upward under the push of its inclined structure, and finally enter the collecting cylinder to assist in the collection of metal impurities. The bottom of the annular plate is fixedly connected to the top of the shell, the bottom of the sleeve is fixedly connected to the top of the shell, the bottom of the fine rotating rod is fixedly connected to one side of the vibration device, the top of the electric push rod is fixedly connected to the top of the inner wall of the shell, and one end of the threaded rod passes through the collecting cylinder and is threadedly connected to the collecting cylinder.

[0006] Furthermore, the vibration device includes a coarse rotating rod, one end of which passes through and is fixedly connected to an oblique screen drum. The motor drives the coarse rotating rod to rotate, thereby driving the oblique screen drum to rotate, and separating the activated carbon and metal impurities through centrifugal force, so that the lighter activated carbon is more easily thrown out of the screen drum, while the heavier and larger metal impurities remain on the inner wall of the oblique screen drum, thereby preventing the metal impurities from affecting the regeneration effect. The bottom of the oblique screen drum is fixedly connected to a corrugated spring piece 1, which prevents the activated carbon from entering the inside of the equipment. When the activated carbon is attached, its own vibration produces elastic deformation to bounce the activated carbon off, thereby preventing the activated carbon from remaining and causing incomplete treatment. The inner side of the corrugated spring piece 1 is fixedly connected to a fixed A fixed plate, the bottom of which is fixedly connected to a driving shaft of a vibration motor, an annular filter plate is fixedly connected to the outer side of the corrugated spring piece 1, and the vibration motor drives the fixed plate to vibrate after starting, and transmits the vibration to the corrugated spring piece 1 and the annular filter plate, so that the activated carbon passes evenly on the annular filter plate, and increases the heating area and improves the heating efficiency during the subsequent heating process; a corrugated spring piece 2 is fixedly connected to the side of the annular filter plate away from the corrugated spring piece 1, and the corrugated spring piece 2 vibrates with the vibration of the annular filter plate, and bounces off the activated carbon attached to its surface to avoid accumulation of activated carbon; the top of the corrugated spring piece 2 is fixedly connected to the top of the inner wall of the shell, and the top of the coarse rotating rod is fixedly connected to the bottom of the fine rotating rod.

[0007] Furthermore, the heating and cooling device includes an upper feed plate, fan blades and a spiral plate. The fan blades rotate to form an airflow, and the activated carbon falling onto the surface of the spiral plate is cooled through the ventilation plate, which helps to quickly cool the activated carbon.

The bottom of the upper feed plate is fixedly connected to an electric heating pipe, the bottom of the upper feed plate is fixedly connected to a hollow net, the inner side of the hollow net is fixedly connected to a baffle plate, and the bottom of the upper feed plate is fixedly connected to a hollow Net 2, the arrangement of hollow net 1 and hollow net 2 is conducive to the circulation of air, accelerates the transfer and diffusion of heat, and improves the heating efficiency. The outer side of the hollow net 2 is fixedly connected with a baffle plate 2. The baffle plate 1 and the baffle plate 2 prevent the activated carbon from directly contacting the electric heating tube 1 and the electric heating tube 2 through the hollow net 1 and the hollow net 2, avoiding direct contact between the activated carbon and the electric heating tube, preventing damage to the electric heating tube, and at the same time slowing down the falling time of the activated carbon when passing through, increasing the residence time of the activated carbon in the heating part, ensuring that the heating treatment time is more sufficient, and making the heating reaction more thorough. The bottom of the upper feed plate is fixedly connected with electric heating pipe 2, and the electric heating pipe 1 and the electric heating pipe 2 heat the activated carbon entering the heating part, so that the activated carbon reaches the required processing temperature and regenerates the inactivated activated carbon. The two work simultaneously to ensure that the activated carbon can be fully and evenly heated.

[0014] S6: The material is discharged, and the cooled activated carbon is slowly discharged through the heating and cooling device.

[0015] The present invention provides an internal heating activated carbon regeneration furnace and a regeneration process. It has the following beneficial effects:

[0016] 1. This internal heating activated carbon regeneration furnace is provided with an oblique scraper to scrape up the metal impurities remaining on the inner wall of the oblique screen drum, and make the metal impurities move inward and upward under the push of its inclined structure, and finally enter the collecting drum to assist in the collection of metal impurities. The motor drives the coarse rotating rod to rotate, driving the oblique screen drum to rotate, and the activated carbon and metal impurities are separated by centrifugal force, so that the lighter activated carbon is more easily thrown out of the screen drum, while the heavier and larger metal impurities are left on the inner wall of the oblique screen drum to prevent the metal impurities from affecting the regeneration effect. The first and second electric heating tubes heat the activated carbon entering the heating part to make the activated carbon reach the required processing temperature, so that the inactivated activated carbon is regenerated. The two act simultaneously to ensure that the activated carbon can be fully and evenly heated, thereby improving the effect and efficiency of the heating treatment.

[0017] 2. This internal heating activated carbon regeneration furnace is provided with a separation and collection device. The oblique scraper scrapes up the metal impurities remaining on the inner wall of the oblique screen drum, and makes the metal impurities move inward and upward under the push of its inclined structure, and finally enter the collecting drum, so as to assist in the collection of metal impurities. The collecting drum is used to temporarily store the metal impurities scraped up from the inner wall of the oblique screen drum to avoid the impurities from scattering everywhere, which is convenient for subsequent centralized processing. When there are too many metal impurities inside, the electric push rod releases the limit on the collecting drum, and the collecting drum moves upward. The annular magnetic block uses its own magnetism to absorb the metal impurities in the collecting drum, which is convenient for cleaning the metal impurities. When the collecting drum moves upward, the folding hose folds and contracts to prevent metal impurities from entering the threaded rod and avoid interfering with the rotation of the threaded rod.

[0018] 3. This internal heating activated carbon regeneration furnace is provided with a vibration device. The motor drives the coarse rotating rod to rotate, driving the inclined screen drum to rotate, and the activated carbon and metal impurities are separated by centrifugal force, so that the lighter activated carbon is more easily thrown out of the screen drum, while the heavier and larger metal impurities remain on the inner wall of the inclined screen drum to prevent the metal impurities from affecting the regeneration effect. After the vibration motor is started, it drives the fixed plate to vibrate, and transmits the vibration to the corrugated spring piece 1 and the annular filter plate, so that the activated carbon passes evenly on the annular filter plate, and the heating area is increased in the subsequent heating process to improve the heating efficiency. The corrugated spring piece 2 vibrates with the vibration of the annular filter plate, and the activated carbon attached to its surface is bounced off to avoid the accumulation of activated carbon. The corrugated spring piece 1 prevents the activated carbon from entering the inside of the equipment. When the activated carbon is attached, its own vibration produces elastic deformation to bounce the activated carbon off to prevent the activated carbon from remaining and causing incomplete treatment.

[0019] 4. The internal heating activated carbon regeneration furnace is provided with a cooling and heating device. The electric heating tube 1 and the electric heating tube 2 heat the activated carbon entering the heating part to make the activated carbon reach the required processing temperature and regenerate the inactivated activated carbon. The two act simultaneously to ensure that the activated carbon can be fully and evenly heated. The setting of the hollow mesh 1 and the hollow mesh 2 is conducive to the circulation of air, accelerates the transfer and diffusion of heat, and improves the heating efficiency. The baffle plate 1 and the baffle plate 2 prevent the activated carbon from directly contacting the electric heating tube 1 and the electric heating tube 2 through the hollow mesh 1 and the hollow mesh 2, avoids direct contact between the activated carbon and the electric heating tube, and prevents damage to the electric heating tube. At the same time, the falling time of the activated carbon is slowed down when passing through, and the residence time of the activated carbon in the heating part is increased, ensuring that the heating treatment time is more sufficient and the heating reaction is more thorough. The fan blades rotate to form an airflow, and the activated carbon falling onto the surface of the spiral plate is cooled through the ventilation plate, which is helpful for the activated carbon to cool quickly. When the spiral plate rotates, the activated carbon is slowly spirally moved downward to increase the cooling time of the activated carbon and make the cooling more sufficient.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The separation and collection device 4 includes an annular plate 41, the top of the annular plate 41 is threadedly connected to a top cover 42, the bottom of the top cover 42 is fixedly connected to an annular magnetic block 43, a sleeve 44 is arranged at the bottom center of the annular plate 41, a motor 45 is fixedly connected to the top of the inner wall of the sleeve 44, a threaded rod 46 is fixedly connected to the driving shaft of the motor 45, a folding hose 47 is fixedly connected to the bottom of the motor 45, a collecting barrel 48 is fixedly connected to the bottom of the folding hose 47, circular grooves 49 are provided on both sides of the bottom of the inner wall of the collecting barrel 48, an electric push rod 410 is arranged on the inner wall of the circular groove 49, a thin rotating rod 411 is fixedly connected to the bottom of the threaded rod 46, an oblique barrel 412 is sleeved and rotatably connected to the thin rotating rod 411, and the oblique barrel 412 is fixedly connected to the inner wall of the collecting barrel 48. An oblique scraper 413 is fixedly connected to the side, the bottom of the annular plate 41 is fixedly connected to the top of the shell 1, the bottom of the sleeve 44 is fixedly connected to the top of the shell 1, the bottom of the thin rotating rod 411 is fixedly connected to one side of the vibration device 6, the top of the electric push rod 410 is fixedly connected to the top of the inner wall of the shell 1, and one end of the threaded rod 46 passes through the collecting tube 48 and is threadedly connected to the collecting tube 48. When in use, the activated carbon is put into the shell 1 from the feeding pipe 2, and the activated carbon passes through the separation and collection device 4 to screen the deactivated activated carbon, remove the mixed metal impurities and collect them, and the screened activated carbon is vibrated evenly by the vibration device 6 and enters the heating and cooling device. The activated carbon moves in the heating and cooling device 7 and is fully The activated carbon is heated to restore its adsorption performance and regenerate the deactivated activated carbon. The regenerated activated carbon is cooled by air cooling in the heating and cooling device 7. The cooled activated carbon is slowly discharged through the heating and cooling device 7. After the activated carbon enters the shell 1 from the feed pipe 2, the motor 45 is started. The driving shaft of the motor 45 rotates to drive the coarse rotating rod 61 to rotate, and the oblique screen drum 62 fixedly connected to the coarse rotating rod 61 rotates. When the oblique screen drum 62 rotates at a high speed, the deactivated activated carbon inside is subjected to the centrifugal force. The lighter activated carbon will be more easily thrown out of the screen drum, while the relatively heavier and larger metal impurities will be left on the inner wall of the oblique screen drum 62. While the oblique screen drum 62 rotates, the oblique scraper 413 scrapes the inner wall of the oblique screen drum 62. The remaining metal impurities are scraped off, and the metal impurities gradually move inward and upward. When they move to the top position of the side of the inclined cylinder 412, they enter the collecting cylinder 48. When there is too much metal inside the collecting cylinder 48, the movable end of the electric push rod 410 moves upward to release the limit on the collecting cylinder 48. The inner wall of the collecting cylinder 48 interacts with the threaded rod 46 and starts to move upward. After moving to a certain position, the annular magnetic block 43 absorbs the metal, and then the top cover 42 is opened, and the metal impurities absorbed on the surface of the annular magnetic block 43 are cleaned and put back for further use. When the collecting cylinder 48 moves upward, the folding hose 47 folds and contracts to prevent metal impurities from entering the thread gap of the threaded rod 46 or being wrapped around the threaded rod 46, thereby ensuring that the threaded rod 46 can rotate normally.

[0033] For the second embodiment, please refer to Figure 1-Figure 9The present invention provides an internal heating activated carbon regeneration furnace and a regeneration process: the vibration device 6 includes a coarse rotating rod 61, one end of the coarse rotating rod 61 penetrates and is fixedly connected with an oblique screen cylinder 62, the bottom of the oblique screen cylinder 62 is fixedly connected with a corrugated spring piece 1 63, the inner side of the corrugated spring piece 1 63 is fixedly connected with a fixing plate 64, the bottom of the fixing plate 64 is fixedly connected with a driving shaft of a vibration motor 65, the outer side of the corrugated spring piece 1 63 is fixedly connected with an annular filter plate 66, the side of the annular filter plate 66 away from the corrugated spring piece 1 63 is fixedly connected with a corrugated spring piece 2 67, the top of the corrugated spring piece 2 67 is fixedly connected to the top of the inner wall of the shell 1, and the top of the coarse rotating rod 61 is fixedly connected to the bottom of the fine rotating rod 411;

[0034] The heating and cooling device 7 includes an upper feed plate 71, a fan blade 710 and a spiral plate 712. The bottom of the upper feed plate 71 is fixedly connected to an electric heating pipe 72, the bottom of the upper feed plate 71 is fixedly connected to a hollow net 73, the inner side of the hollow net 73 is fixedly connected to a baffle plate 74, the bottom of the upper feed plate 71 is fixedly connected to a hollow net 75, the outer side of the hollow net 75 is fixedly connected to a baffle plate 76, the bottom of the upper feed plate 71 is fixedly connected to an electric heating pipe 77, the bottom of the upper feed plate 71 is fixedly connected to an air duct 78, the bottom of the air duct 78 is fixedly connected to a lower feed plate 79, the bottom of the inner wall of the air duct 78 is fixedly connected to a ventilation plate 711, the side of the upper feed plate 71 is fixedly connected to the inner wall of the shell 1, and the side of the lower feed plate 79 is fixedly connected to the shell 1 The inner wall of the coarse rotating rod 61 is fixedly connected, the upper feed plate 71 is sleeved on the coarse rotating rod 61 and is rotatably connected to the coarse rotating rod 61, one side of the fan blade 710 is fixedly connected to the side of the coarse rotating rod 61, the ventilation plate 711 is sleeved on the coarse rotating rod 61 and is rotatably connected to the coarse rotating rod 61, the spiral plate 712 is sleeved on the coarse rotating rod 61 and is fixedly connected to the coarse rotating rod 61, the bottom of the electric heating tube 1 72 is fixedly connected to the top of the lower feed plate 79, the bottom of the hollow net 1 73 is fixedly connected to the top of the lower feed plate 79, the bottom of the hollow net 2 75 is fixedly connected to the top of the lower feed plate 79, and the bottom of the electric heating tube 2 77 is fixedly connected to the top of the lower feed plate 79. When in use, start the motor 45, the driving shaft of the motor 45 rotates to drive the coarse rotating rod 61 to rotate, and is fixedly connected to the coarse rotating rod 61 The oblique screen drum 62 rotates. When the oblique screen drum 62 rotates at a high speed, the inactivated activated carbon inside is affected by the centrifugal force, and the lighter activated carbon will be more easily thrown out of the screen drum, while the relatively heavier and larger metal impurities will be left on the inner wall of the oblique screen drum 62. The vibration motor 65 starts, driving the fixed plate 64 to vibrate, and the corrugated spring piece 63 connected to the fixed plate 64 vibrates accordingly, driving the annular filter plate 66 fixedly connected to the outer side of the corrugated spring piece 63 to vibrate. After the activated carbon is screened and separated by the oblique screen drum 62, it enters the surface of the annular filter plate 66, and evenly passes through the annular filter plate 66 after being vibrated. The activated carbon thrown out by the oblique screen drum 62 may adhere to the surface of the corrugated spring piece 63. When the annular filter plate 66 vibrates, it will drive the corrugated spring piece 63 to vibrate. The corrugated spring piece 1 63 undergoes elastic deformation during the vibration process, and the activated carbon attached to the surface is bounced off. The corrugated spring piece 2 67 prevents the activated carbon from entering the inside. When the activated carbon is attached to the corrugated spring piece 2 67 during the vibration process, since the corrugated spring piece 2 67 is also affected by the vibration caused by the vibration motor 65, it will also undergo elastic deformation. This elastic deformation of the corrugated spring piece 2 67 will also generate a force to bounce off the activated carbon attached to its surface. The activated carbon evenly passes through the upper feed plate 71 and enters the heating part. The electric heating tube 1 72 and the electric heating tube 2 77 act at the same time to heat the inactivated activated carbon. The inner side of the electric heating tube 1 72 is provided with a hollow mesh 1 73, and the outer side of the electric heating tube 2 77 is provided with a hollow mesh 2 75, which is conducive to the circulation of air. During the heating process,Air can flow freely through the pores of the hollow mesh, which can accelerate the transfer and diffusion of heat and make the heating efficiency higher. When the activated carbon passes through the baffle plate 1 74 and the baffle plate 2 76, the falling time will be slowed down, the heating treatment time will be increased, and the reaction will be more complete. At the same time, the activated carbon is prevented from directly contacting the electric heating tube 1 72 and the electric heating tube 2 77 through the hollow mesh 1 73 and the hollow mesh 2 75. After the activated carbon is heated, it enters the spiral plate 712 through the lower feed plate 79. When the motor 45 rotates, the coarse rotating rod 61 rotates at the same time, driving the fan blades 710 and the spiral plate 712 to rotate. The fan blades 710 rotate to form airflow, and the activated carbon falling on the surface of the spiral plate 712 is cooled through the ventilation plate 711. The spiral plate 712 rotates to slowly spirally move the activated carbon downward and discharge it from the discharge port at the bottom of the shell 1.

[0035] A method for using an internally heated activated carbon regeneration furnace comprises the following steps:

[0036] S1: Put the material into the shell 1 through the feed pipe 2;

[0037] S2: Separating materials, the activated carbon passes through the separation and collection device 4, the deactivated activated carbon is screened, the mixed metal impurities therein are removed and collected;

[0038] S3: Even the material, the screened activated carbon is vibrated evenly by the vibration device 6 and enters the heating and cooling device 7;

[0039] S4: heating treatment, the activated carbon moves in the heating and cooling device 7 and is fully heated to restore the adsorption performance of the activated carbon and regenerate the deactivated activated carbon;

[0040] S5: cooling treatment, the regenerated activated carbon is cooled by air cooling in the heating and cooling device 7;

[0041] S6: The material is discharged, and the cooled activated carbon is slowly discharged through the heating and cooling device 7.

[0042] When the present invention is operated and used, the activated carbon is put into the shell 1 from the feed pipe 2, the activated carbon passes through the separation and collection device 4, the inactivated activated carbon is screened, the mixed metal impurities therein are removed and collected, the screened activated carbon is vibrated evenly by the vibration device 6, and enters the heating and cooling device, the activated carbon moves in the heating and cooling device 7 and is fully heated, the adsorption performance of the activated carbon is restored, the inactivated activated carbon is regenerated, the regenerated activated carbon is cooled by air cooling in the heating and cooling device 7, the cooled activated carbon is slowly discharged through the heating and cooling device 7, after the activated carbon enters the shell 1 from the feed pipe 2, the motor 45 is started, the driving shaft of the motor 45 rotates to drive the coarse rotating rod 61 to rotate, the oblique screen drum 62 fixedly connected to the coarse rotating rod 61 rotates, and when the oblique screen drum 62 is rotated, the coarse rotating rod 61 rotates. When the screen drum 62 rotates at a high speed, the deactivated activated carbon inside is affected by the centrifugal force, and the lighter activated carbon will be more easily thrown out of the screen drum, while the relatively heavier and larger metal impurities will be left on the inner wall of the inclined screen drum 62. While the inclined screen drum 62 rotates, the inclined scraper 413 scrapes up the metal impurities remaining on the inner wall of the inclined screen drum 62, and the metal impurities gradually move inward and upward, and when they move to the top position of the side of the inclined drum 412, they enter the collecting drum 48. When there is too much metal inside the collecting drum 48, the movable end of the electric push rod 410 moves upward to release the limit on the collecting drum 48. The inner wall of the collecting drum 48 interacts with the threaded rod 46 and starts to move upward. After moving to a certain position, the annular magnetic block 43 absorbs the metal, and then the top cover 42 is opened to press the surface of the annular magnetic block 43. The adsorbed metal impurities are cleaned and put back for continued use. When the collecting cylinder 48 moves upward, the folding hose 47 is folded and contracted to prevent metal impurities from entering the thread gap of the threaded rod 46 or being entangled on the threaded rod 46, thereby ensuring that the threaded rod 46 can rotate normally. The vibration motor 65 is started, driving the fixed plate 64 to vibrate, and the corrugated spring piece 63 connected to the fixed plate 64 vibrates accordingly, driving the annular filter plate 66 fixedly connected to the outer side of the corrugated spring piece 63 to vibrate. After the activated carbon is screened and separated by the oblique screen cylinder 62, it enters the surface of the annular filter plate 66 and passes through the annular filter plate 66 evenly after the vibration treatment. The activated carbon thrown out by the oblique screen cylinder 62 may adhere to the surface of the corrugated spring piece 63. When the annular filter plate 66 vibrates, it will drive the corrugated spring piece 63 Vibration, the corrugated spring piece 1 63 undergoes elastic deformation during the vibration process, and the activated carbon attached to the surface is bounced off. The corrugated spring piece 2 67 prevents the activated carbon from entering the inside. When the activated carbon is attached to the corrugated spring piece 2 67 during the vibration process, since the corrugated spring piece 2 67 is also affected by the vibration caused by the vibration motor 65, it will also undergo elastic deformation. This elastic deformation of the corrugated spring piece 2 67 will also generate a force to bounce off the activated carbon attached to its surface. The activated carbon evenly enters the heating part through the upper feed plate 71. The electric heating tube 1 72 and the electric heating tube 2 77 act at the same time to heat the inactivated activated carbon. The inner side of the electric heating tube 1 72 is provided with a hollow mesh 1 73, and the outer side of the electric heating tube 2 77 is provided with a hollow mesh 2 75, which is conducive to the circulation of air. During the heating process,Air can flow freely through the pores of the hollow mesh, which can accelerate the transfer and diffusion of heat and make the heating efficiency higher. When the activated carbon passes through the baffle plate 1 74 and the baffle plate 2 76, the falling time will be slowed down, the heating treatment time will be increased, and the reaction will be more complete. At the same time, the activated carbon is prevented from directly contacting the electric heating tube 1 72 and the electric heating tube 2 77 through the hollow mesh 1 73 and the hollow mesh 2 75. After the activated carbon is heated, it enters the spiral plate 712 through the lower feed plate 79. When the motor 45 rotates, the coarse rotating rod 61 rotates at the same time, driving the fan blades 710 and the spiral plate 712 to rotate. The fan blades 710 rotate to form airflow, and the activated carbon falling on the surface of the spiral plate 712 is cooled through the ventilation plate 711. The spiral plate 712 rotates to slowly spirally move the activated carbon downward and discharge it from the discharge port at the bottom of the shell 1.
