Description

[Technical Field]

[0001] The present invention relates to the technical field of activated carbon regeneration, and more particularly to an oxidation-free continuous regeneration and cooling production line for powdered activated carbon. [Background technology]

[0002] The regeneration temperature of the regeneration furnace used to produce activated carbon is approximately 850-950°C, and the activated carbon must be kept at a temperature of 850-950°C in the regeneration furnace. A large amount of smoke is generated during the regeneration process of the activated carbon raw material, but the smoke exhaust path must match the route through which the carbon powder is discharged when the regeneration furnace completes the regeneration process. The temperature of the carbon powder reaches 850°C during the discharge process, and if it is discharged at a high temperature, it must be quickly blocked from oxygen and cooled. Otherwise, the powdered activated carbon will burn out and there is a risk of deflagration. Therefore, the regeneration furnace must be directly connected to a cooling mechanism.

[0003] The cooling equipment needs to cool the high-temperature coal powder to 40°C, but in actual operation, in order to ensure the discharge temperature of the coal powder, a cooling effect that supersaturates the coal powder is required, which requires that the coal powder contact time with the cooling mechanism be long enough, thus limiting the discharge speed of the coal powder and increasing the loss of the cooling mechanism, which increases the production cost of the coal powder. Summary of the Invention

[0004] In order to overcome the above technical problems, the object of the present invention is to provide an oxidation-free, continuous regenerative cooling production line for powdered activated carbon, which solves the problem that in the prior art, in order to ensure the discharge temperature of the carbon powder, a cooling effect that supersaturates the carbon powder is required, i.e., the carbon powder needs to have a sufficiently long contact time with the cooling mechanism, resulting in a low discharge rate of the carbon powder and high loss in the cooling mechanism.

[0005] The object of the present invention can be achieved by the following technical means.

[0011] According to a further embodiment of the present invention, the material supply mechanism comprises: A frame with a track on top; a buffer silo provided on the truck and having a traveling mechanism at the bottom that matches the truck; a feed spiral pipe provided at the discharge port of the buffer silo; A feed bin is provided on the top of the track, a conveyor belt is provided at the discharge port of the feed bin, one end of the conveyor belt away from the feed bin is provided at the top of the buffer silo, and rolling wheels that are engaged with the track are provided at the bottom of both the feed bin and the buffer silo.

[0012] According to a further embodiment of the present invention, the feed spiral pipe includes a feed pipe having a support fixedly connected to its bottom surface, a feed motor connected to one end, a screw rod provided inside the feed pipe that is operatively connected to the feed motor, and a feed chute opened at its top surface near the discharge port of the buffer silo.

[0013] According to a further embodiment of the present invention, the traveling mechanism includes a reducer having a drive motor connected to its power input end and a drive shaft connected to its power output end, a bearing housing nested in the center position on the side of the drive shaft, and an internal drive wheel matching with the truck fixedly connected to one end of the drive shaft away from the reducer.

[0014] According to a further embodiment of the present invention, the automatic docking tube includes a docking tube having a plurality of sectorial baffle plates at one end remote from the smoke removal pipe, and an output port is provided at one end of the heating tube close to the docking tube, and the central axis of the output port overlaps with the central axis of the docking tube; A stopper groove is formed on the end surface of the output port to be engaged with the sectorial baffle plate, and the positions of the sectorial baffle plate and the positions of the stopper groove correspond one-to-one.

[0015] According to a further embodiment of the present invention, the docking tube has a plurality of arc-shaped protrusions uniformly distributed on its side surface, which are in contact with the inner wall of the smoke removal pipe.

[0016] According to a further embodiment of the present invention, a plurality of ball nuts are provided on the end face of one end of the docking tube near the sectorial baffle plate, a threaded rod that engages with the ball nuts is fixedly connected to the side of the sectorial baffle plate, a stop collar is provided at the tip position of the side of the sectorial baffle plate, and a limit lever that engages with the stop collar is fixedly connected to the inner wall of the docking tube at a position near the stop collar.

[0017] According to a further embodiment of the present invention, a drive gear is provided at one end of the side of the docking tube away from the sector-shaped baffle plate, and a tooth groove that engages with the drive gear is opened at a position close to the drive gear on the inner wall of the smoke removal pipe, a transmission rod is meshed with the inside of the drive gear, a transmission ring gear is meshed with one end of the transmission rod away from the drive gear, a driven gear is meshed with one side of the transmission ring gear away from the transmission rod, and the driven gear is meshed with the side of the ball nut.

[0018] The effects of the present invention are as follows. In the present invention, a sealed pipe is provided between the regeneration furnace and the cooling mechanism, which provides a hermetically sealed flexible connection between the regeneration furnace and the cooling mechanism, ensuring that the activated carbon in the heating pipe remains sealed at high temperatures, thereby preventing oxygen from the external environment from entering the heating pipe, reducing carbon loss during the regeneration process, and improving the yield of regenerated carbon powder.

[0019] In the present invention, the regeneration furnace and the cooling mechanism are both mounted on the top of the base, so adjusting the inclination angle of the base allows the inclination angles of the regeneration furnace and the cooling mechanism to be adjusted simultaneously. The base is tilted toward the regeneration furnace using a hydraulic cylinder, meaning the height of the regeneration furnace is smaller than the height of the cooling mechanism. In this way, the automatic docking tube automatically slides toward the end closest to the heating tube under the force of its own gravity and contacts the outlet end of the heating tube, ensuring communication between the smoke removal pipe and the heating tube. In this way, smoke generated in the heating tube is transported through the automatic docking tube to the smoke removal pipe, which then discharges the smoke through the high-temperature smoke pipe, achieving smoke discharge. Furthermore, because the height of the regeneration furnace is smaller than that of the cooling mechanism, the end of the heating tube closest to the automatic docking tube is higher than the end closest to the material supply mechanism, preventing the activated carbon raw material in the heating tube from leaking into the automatic docking tube during the regeneration process.

[0020] The hydraulic cylinder tilts the base toward the cooling mechanism, i.e., the height of the regeneration furnace is greater than that of the cooling mechanism. In this way, the automatic docking tube automatically slides toward the end closest to the smoke removal pipe under the action of its own gravity, ensuring that the automatic docking tube and the outlet end of the heating tube are no longer in contact. A spiral plate is installed on the inner wall of the outlet end of the heating tube. When the heating tube is driven to rotate by an external force, the end of the heating tube closest to the smoke removal pipe is lower than the other end, so that the regenerated carbon powder in the heating tube flows to the outlet end of the heating tube and is discharged into the cooling mechanism by the action of the spiral plate. This separates the smoke and the regenerated carbon powder, preventing residual smoke from being mixed into the regenerated carbon powder and improving the purity of the regenerated carbon powder.

[0021] In the present invention, a cooling control module is provided to ensure that the temperature of the coal powder discharged from the coal powder pipe is cooled to a set value. At the same time, the flow rate of the coal powder in the coal powder pipe is changed according to the inclination angle of the cold converter. That is, the greater the inclination angle of the cold converter, the faster the flow rate of the coal powder in the coal powder pipe; and the smaller the inclination angle of the cold converter, the slower the flow rate of the coal powder in the coal powder pipe. The inclination angle a obtained by the cooling control module is the optimal inclination angle for cooling the coal powder temperature to the set value, ensuring the flow rate of the coal powder and the cooling effect of the coal powder. When the flow rate of the coal powder is ensured, the discharge efficiency of the coal powder is ensured, making the powdered activated carbon oxidation-free continuous regeneration cooling production line very suitable for large-scale production and automated production.

[0024] The following will clearly and completely describe the technical means in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative ingenuity fall within the protection scope of the present invention.

[0025] [Example 1] As shown in Figures 1 and 2, the present invention discloses a non-oxidizing, continuous regenerative cooling production line for powdered activated carbon. The production line specifically includes a regenerative furnace 1, which is equipped with a heating tube 2 that can be heated electrically, by natural gas, or by fuel. Electric heating uses an electric heating element, primarily silicon carbide rods, which have the advantages of good heating efficiency, rapid temperature rise, and easy maintenance and replacement. A cooling mechanism 4 is installed at one end of the regenerative furnace 1, and a sealed tube 8 is connected between the regenerative furnace 1 and the cooling mechanism 4. A base 3 is installed at the bottom of the base 3, and a hydraulic cylinder 31 is attached to the bottom of the base 3 to control the tilt angle of the regenerative furnace 1 and the cooling mechanism 4. The cooling mechanism 4 is equipped with a cooling control module that acquires the temperature of the coal powder at the intermediate position of the cooling mechanism 4, the temperature of the coal powder at the outlet position, the tilt angle and rotation speed of the cooling mechanism 4, constructs a computer linear regression model, and predicts the tilt angle and rotation speed that the cooling mechanism 4 needs to control based on the temperature of the coal powder at the intermediate position of the cooling mechanism 4 according to the computer linear regression model, and causes the temperature of the coal powder at the outlet position of the cooling mechanism 4 to reach a preset value.

[0026] A material supply mechanism 5 is provided at the other end of the regeneration furnace 1. Inside the cooling mechanism 4, a smoke removal pipe 6 is provided, one end of which is connected to a high-temperature smoke pipe 9 and the other end of which is provided with a movable automatic docking pipe 7.

[0027] The heating tube 2 is inserted horizontally along the central axis of the regeneration furnace 1. The heating tube 2, which is heated electrically, by natural gas, or by fuel, is provided inside the regeneration furnace 1. The temperature of the heating tube 2 is controlled to 850°C to 950°C, and the heating tube 2 must be kept at that temperature for 40 to 60 minutes, thereby removing moisture and organic matter from the activated carbon inside the heating tube 2.

[0028] The sealed pipe 8 is provided between the regeneration furnace 1 and the cooling mechanism 4, which provides a hermetically sealed flexible connection between the regeneration furnace 1 and the cooling mechanism 4, ensuring that the activated carbon in the heating pipe 2 remains sealed at high temperatures. This prevents oxygen from the external environment from entering the heating pipe 2, reducing carbon loss during the activated carbon regeneration process.

[0029] The hydraulic cylinder 31 drives the pedestal 3 with a hydraulic rod, thereby adjusting the tilt angle of the pedestal 3. Since the regeneration furnace 1 and the cooling mechanism 4 are both installed on the top surface of the pedestal 3, adjusting the tilt angle of the pedestal 3 allows the tilt angles of the regeneration furnace 1 and the cooling mechanism 4 to be adjusted simultaneously.

[0030] Specifically, when the activated carbon raw material is added to the heating tube 2, the hydraulic cylinder 31 tilts the base 3 toward the regeneration furnace 1, i.e., the height of the regeneration furnace 1 is smaller than the height of the cooling mechanism 4. In this way, the automatic docking tube 7 automatically slides to the end close to the heating tube 2 under the action of its own gravity and contacts the outlet end of the heating tube 2, ensuring that the smoke removal pipe 6 communicates with the heating tube 2. In this way, the smoke generated in the heating tube 2 can be transported to the smoke removal pipe 6 through the automatic docking tube 7, and the smoke removal pipe 6 discharges the smoke through the high-temperature smoke pipe 9, thereby achieving smoke discharge. Furthermore, because the height of the regeneration furnace 1 is smaller than the height of the cooling mechanism 4, the end of the heating tube 2 close to the automatic docking tube 7 is higher than the end close to the material supply mechanism 5, preventing the activated carbon raw material in the heating tube 2 from leaking into the automatic docking pipe 7 during the regeneration process.

[0031] When the regeneration of the activated carbon raw material in the heating tube 2 is completed, the hydraulic cylinder 31 tilts the base 3 toward the cooling mechanism 4, i.e., the height of the regeneration furnace 1 is greater than that of the cooling mechanism 4. In this way, the automatic docking tube 7 automatically slides toward the end closer to the smoke removal pipe 6 under the action of its own gravity, ensuring that the automatic docking tube 7 and the outlet end of the heating tube 2 are no longer in contact. As shown in FIG. 2, a spiral plate is installed on the inner wall of the outlet end of the heating tube 2. When the heating tube 2 is driven to rotate by an external force, the end of the heating tube 2 closer to the smoke removal pipe 6 is lower than the other end, so that the regenerated carbon powder in the heating tube 2 flows toward the outlet end of the heating tube 2 and is discharged to the cooling mechanism 4 by the action of the spiral plate, where it can be cooled.

[0032] As shown in Figure 3, the cooling mechanism 4 has a first support roller 42 and a second support roller 43 at both ends of its bottom surface, and includes a cold converter 41 with a converter motor 44 at one end away from the regeneration furnace 1, and the output shaft of the converter motor 44 is engaged with the side of the cold converter 41 by a gear.

[0033] A first tire 421 is provided on the top surface of the cold converter 41 at a top position near the first support roller 42, and a second tire 431 is provided on the top surface of the cold converter 41 at a top position near the second support roller 43, so that the power of the converter motor 44 is transmitted to the cold converter 41 by gears, enabling the cold converter 41 to rotate. The cold converter 41 and the heating tube 2 are connected by a sealed tube 8, so that the rotating cold converter 41 can move the heating tube 2 via the sealed tube 8, thereby rotating synchronously. A spiral plate is provided on the inner wall of the outlet end of the heating tube 2, so that the delivery of activated carbon inside the heating tube 2 can be controlled by controlling the rotation direction of the heating tube 2.

[0034] 3 and 4, a water-cooled pipe 45 is inserted into one end of the cold converter 41 away from the regenerator 1, and a plurality of coal powder pipes 46 and a water-cooled groove 47 are formed inside the cold converter 41. The coal powder pipes 46 are arranged uniformly at the edges of the cold converter 41, and the water-cooled pipes 45 communicate with the water-cooled grooves 47. The water-cooled pipe 45 includes a water inlet pipe 451 having a water inlet port 453 at one end and a docking pipe 455 at the other end, and a water outlet pipe 452 inside. The water outlet pipe 452 has a water outlet port 454 at one end and a docking pipe 455 at the other end, and the docking pipe 455 communicates with the water-cooled groove 47.

[0035]

[0023] In addition, the screw groove formed inside the coal powder pipe 46 increases the contact area between the inner wall of the coal powder pipe 46 and the coal powder, improving the heat dissipation effect of the coal powder, and the screw groove also serves to guide the coal powder, i.e., increase the flow time of the coal powder in the coal powder pipe 46, ensuring that the coal powder can fully dissipate heat. The water inlet pipe 451 is connected to a cold water source in the external environment via a water inlet port 453, which ensures that the cold water source can deliver cooling water to the water inlet pipe 451, which delivers the cooling water via a docking pipe 455 to the water cooling groove 47. The cooling water in the water cooling groove 47 exchanges heat with the high-temperature coal powder in the coal powder pipe 46, reducing the temperature of the coal powder and cooling it. After absorbing heat, the cooling water in the water cooling groove 47 can enter the outlet pipe 452 through the docking pipe 455 connected to the outlet pipe 452, and the outlet pipe 452 sends out the cooling water through the outlet port 454, thereby realizing the circulation of the cooling water.

[0036] As shown in FIG. 5, the temperature t of the charcoal powder in the charcoal powder pipe 46 is measured at both ends and the middle position of the charcoal powder pipe 46. 入 , t 中 and t 出 Temperature sensors are provided to monitor each of the

[0037] Among them, t 入 is the temperature of the coal powder at the port at one end of the coal powder pipe 46 close to the cold converter 41, and t 中 is the temperature of the coal powder at a point close to the center of the coal powder pipe 46, and t 出 is the temperature of the coal powder at the port at one end of the coal powder pipe 46 away from the cold converter 41, and the temperature sensor is 入 , t 中 and t 出 is converted into an electrical signal and transmitted to the cooling control module.

[0038] In addition, t 入 is the temperature at which the regenerated coal powder in the heating tube 2 enters the coal powder tube 46, and is between 850°C and 950°C. 出 is the temperature after the coal powder is cooled by the coal powder pipe 46, and is usually controlled to be below 40°C. 中is the temperature at which the coal particles have traveled half the distance in the coal particle tube 46, i.e., the temperature to which the coal particles have cooled in half the time. 入 When the temperature of the coal powder is high, the coal powder pipe 46 must absorb more heat from the coal powder to complete the cooling of the coal powder.

[0039] A rotation speed sensor is attached to one end of the cold converter 41 near the converter motor 44 to monitor the rotation speed n of the cold converter 41, convert the rotation speed n into an electrical signal, and transmit it to the cooling control module.

[0040] A gyro is attached to the center position of the bottom of the cold converter 41 to monitor the tilt angle a of the cold converter 41, convert the tilt angle a into an electrical signal, and transmit it to the cooling control module.

[0041] The cooling control module constructs a computer linear regression model using the following equation: t 出 =A×t 入 +B×t 中 +C×n+D×a. Among them, A, B, C, and D are all constants f. When cooling coal powder, some cooling data can be input into the computer linear regression model. The cooling data is t 入 , t 中 , t 出 , n and a, and a computer linear regression model determines the values of A, B, C and D.

[0042] That is, the values of the rotation speed n of the cold converter 41 and the tilt angle a of the cold converter 41 are preset, and after the coal powder is cooled by the cold converter 41, the temperatures , , and of the coal powder in the coal powder pipe 46 are obtained by temperature sensors at both ends and the middle position of the coal powder pipe 46. Multiple sets of values of the rotation speed n of the cold converter 41 and the tilt angle a of the cold converter 41 can be installed as needed, and then the temperatures t of the coal powder in the coal powder pipe 46 corresponding to the multiple sets of values of the rotation speed n of the cold converter 41 and the tilt angle a of the cold converter 41 can be obtained.入 , t 中 and t 出 Obtain the formula "t 出 =A×t 入 +B×t 中 +C×n+D×a" and determine the values of A, B, C, and D using a computer linear regression model.

[0043] The cooling control module is preset by manual input. 出(プリ) Get, for example, t 出(プリ) The cooling control module also uses a temperature sensor to 入 and t 中 was obtained. t 出(プリ) =A×t 入 +B×t 中 +C×n+D×a; C×n+D×a=t 出(プリ) -(A×t 入 +B×t 中 ).

[0044] When the rotation speed n of the cold converter 41 does not change, that is, when the rotation speed n of the cold converter 41 does not change, the rotation speed n of the cold converter 41 is maintained. a プリ =[t 出(プリ) -(A×t 入 +B×t 中 +C×n)] / D

[0045] Incline angle a プリ The cooling control module measures the temperature of the carbon powder by the temperature sensor. 中 Monitors the preset time 出(プリ) Based on this, the tilt angle required when predicting that the rotation speed of the cold converter of the base 3 is n. When the inclination angle a of the cold converter 41 does not change, the inclination angle a of the cold converter 41 is maintained so as not to change. n プリ =t 出(プリ) -(A×t 入 +B×t 中 +D×a)] / C

[0046] rotation speed n プリ The cooling control module measures the temperature of the carbon powder by the temperature sensor. 入 and t 中 Monitors the preset time 出(プリ) Based on the above, the required rotation speed is calculated when the inclination angle of the base 3 of the cold converter is predicted to be a.

[0047] In this way, it is possible to ensure that the temperature of the coal powder sent out from the coal powder pipe 46 is cooled to a set value. At the same time, the flow speed of the coal powder in the coal powder pipe 46 is changed according to the inclination angle of the cold converter 41. That is, the larger the inclination angle of the cold converter 41, the faster the flow speed of the coal powder in the coal powder pipe 46. The smaller the inclination angle of the cold converter 41, the slower the flow speed of the coal powder in the coal powder pipe 46. プリ =[t 出(プリ) -(A×t 入 +B×t 中 +C×n)] / D" is the optimal inclination angle a for cooling the coal powder temperature to the set value, ensuring the flow rate of the coal powder and the cooling effect of the coal powder. When the flow rate of the coal powder is ensured, the discharge efficiency of the coal powder is ensured, making the powdered activated carbon oxidation-free continuous regeneration cooling production line very suitable for large-scale production and automated production.

[0048] [Example 2] As shown in Figures 6, 7 and 8, the material supply mechanism 5 includes a frame 51 with a track 52 attached to the top thereof, a buffer silo 55 attached to the track 52, and a feed spiral pipe 56 attached to the discharge port of the buffer silo 55. A traveling mechanism 58 that matches with the track 52 is attached to the bottom of the buffer silo 55. A feed bin 53 is attached to the top of the track 52. A conveyor belt 54 is attached to the discharge port of the feed bin 53. One end of the conveyor belt 54 away from the feed bin 53 is attached to the top of the buffer silo 55. Rolling wheels 57 that engage with the track 52 are attached to the bottom of both the feed bin 53 and the buffer silo 55.

[0049] The feed bin 53 and the buffer silo 55 are fixed in position, and both are mounted on the track 52 by rolling wheels 57, which allow them to move freely horizontally on the track 52. The feed bin 53 is used to feed activated carbon raw material, which passes through a discharge port at the bottom of the feed bin 53 and falls onto the top of the conveyor belt 54. When it hits the conveyor belt 54, it is automatically dispersed, achieving the effect of laying the activated carbon raw material flat. The conveyor belt 54 then transports the flat-laid activated carbon raw material to the buffer silo 55, and the activated carbon raw material in the buffer silo 55 enters the feed spiral pipe 56 through a discharge port at the bottom of the buffer silo 55.

[0050] As shown in FIG. 8, the feed spiral pipe 56 includes a feed pipe 561 having a support base 562 fixedly connected to its bottom surface, a feed motor 564 connected to one end thereof, a screw rod 565 operatively connected to the feed motor 564 inside thereof, and a feed chute 563 opened at its top surface near the discharge port of the buffer silo 55.

[0051] The feed motor 564 drives the screw rod 565 to rotate via a coupling, and when the activated carbon raw material in the buffer silo 55 enters the feed chute 563 from the discharge port, the rotating screw rod 565 moves the activated carbon raw material, causing it to move inside the feed pipe 561, thereby realizing the transportation of the activated carbon raw material.

[0052] 9 and 10, the traveling mechanism 58 includes a reducer 581 having a drive motor 582 connected to its power input end and a drive shaft 583 connected to its power output end, a bearing housing 584 nested in the center position on the side of the drive shaft 583, and an internal drive wheel 585 that matches the track 52 is fixedly connected to one end of the drive shaft 583 away from the reducer 581. A gravity sensor is provided on the support base 562 to monitor the weight g of the feed pipe 561.

[0053] When the driving motor 582 is turned on, the driving motor 582 drives the reducer 581, and the reducer 581 rotates the built-in driving wheel 585 via the driving shaft 583, so that the built-in driving wheel 585 is matched with the track 52. In this way, the rotating built-in driving wheel 585 moves the feed bin 53 and the buffer silo 55, allowing them to travel freely horizontally on the track 52.

[0054] As shown in FIG. 11, the material supply mechanism 5 is further equipped with a material supply control module that controls the running speed V of the feed spiral tube 56 moved by the running mechanism 58 based on the rotation speed of the reducer 581.

[0055] The material supply control module constructs a computer regression algorithm model according to the following formula: t 空 ×V×S 管 ×n=g 炭 ×ρ. Among them, ρ is the average density of the activated carbon raw material, and S 管 is the inner cross-sectional area of the heating tube 2, and t 空 is the time required for the feed pipe 561 to discharge the activated carbon raw material, and g 炭 is the total weight of the discharged activated carbon raw material, n is a coefficient whose possible value range is 1 / 3 to 1 / 2, and V is the running speed required for the running mechanism 58 to move the feed spiral tube 56, as predicted by the material supply control module. V=(g 炭 ×ρ) / (t 空 ×n×S 管 ).

[0056] The gravity sensor measures the weight (g) of the feed tube 561 when it is idling. 空 and the weight of the feed tube 561 when fully loaded (g) 総 If you want to get g 炭 =g 総 -g 空 ; V=[(g 総 -g 空 )×ρ] / (g 空 ×n×S 管 ) If n can take on a value of 1 / 2, then V = 2 × [(g 総 -g 空 )×ρ] / (t 空 ×S 管 )

[0057] The material supply control module detects the weight g of the feed tube 561 when it is idling. 空 and the weight of the feed tube 561 when fully loaded (g) 総 and get t 空、 S 管 and ρ are all fixed values. Therefore, the material supply control module can calculate the running speed V required for the running mechanism 58 to move the feed spiral tube 56. When the feed spiral tube 56 leaves the heating tube 2 at the running speed V, it can ensure that the amount of activated carbon raw material added to the heating tube 2 does not exceed half of the cavity of the heating tube 2, ensuring that the activated carbon raw material is introduced evenly and that space is left for smoke circulation, ensuring that the activated carbon raw material can be normally regenerated.

[0058] [Example 3] As shown in Figure 12, the automatic docking tube 7 includes a docking tube 71 having a plurality of fan-shaped baffle plates 72 at one end remote from the smoke removal pipe 6, and an output port 21 is provided at one end of the heating tube 2 close to the docking tube 71, and the central axis of the output port 21 overlaps with the central axis of the docking tube 71.

[0059] When the regenerator 1 and the cooling mechanism 4 are inclined as a whole toward the regenerator 1, the docking pipe 71 moves to one end of the output port 21 due to the action of gravity and comes into contact with the output port 21. In this case, the output port 21 is connected to the smoke removal pipe 6 via the docking pipe 71.

[0060] As shown in Figures 12 and 17, a stopper groove 22 that engages with a sectorial baffle plate 72 is opened on the end surface of the output port 21, and the positions of the sectorial baffle plate 72 and the stopper groove 22 correspond one-to-one.

[0061] The shape of the stopper groove 22 matches the shape of the sectorial baffle plate 72, so that when the sectorial baffle plate 72 is deployed at the end face of the docking tube 71, the sectorial baffle plate 72 fits perfectly into the stopper groove 22. The stopper groove 22 limits the position of the sectorial baffle plate 72 to ensure that the sectorial baffle plate 72 is in the deployed state, and also matches with the sectorial baffle plate 72 to ensure a tight seal at the docking site between the docking tube 71 and the output port 21, preventing smoke from leaking during smoke transport.

[0062] As shown in FIGS. 13, 15 and 16, a plurality of arc-shaped protrusions 711 that come into contact with the inner wall of the smoke removal pipe 6 are uniformly distributed on the side surface of the docking tube 71 .

[0063] Furthermore, because the arc-shaped protrusion 711 extends beyond the side surface of the docking tube 71, when the docking tube 71 slides along the inner wall of the smoke detergency pipe 6, the arc-shaped protrusion 711 comes into contact with the inner wall of the smoke detergency pipe 6, and the contact area between the arc-shaped protrusion 711 and the inner wall of the smoke detergency pipe 6 is extremely small. This significantly reduces the friction between the side surface of the docking tube 71 and the inner wall of the smoke detergency pipe 6, allowing the docking tube 71 to slide smoothly along the inner wall of the smoke detergency pipe 6.

[0064] As shown in Figure 14, a plurality of ball nuts 713 are provided on the end face of one end of the docking tube 71 near the sectorial baffle plate 72, a threaded rod 722 that engages with the ball nuts 713 is fixedly connected to the side of the sectorial baffle plate 72, a stop collar 721 is provided at the tip position of the side of the sectorial baffle plate 72, and a limit lever 712 that engages with the stop collar 721 is fixedly connected to a position near the stop collar 721 on the inner wall of the docking tube 71.

[0065] 14 and 17, a drive gear 714 is provided on one end of the side of the docking tube 71 remote from the sectorial baffle plate 72, a toothed groove for engaging with the drive gear 714 is provided on the inner wall of the smoke removal pipe 6 near the drive gear 714, a transmission rod 715 is meshed with the inside of the drive gear 714, a transmission ring gear 716 is meshed with the end of the transmission rod 715 remote from the drive gear 714, a driven gear 717 is meshed with the end of the transmission ring gear 716 remote from the transmission rod 715, and the driven gear 717 is meshed with the side of the ball nut 713. A vacuum motor is connected to the end of the high-temperature smoke pipe 9 remote from the cooling mechanism 4, a permanent magnet 23 is provided on the inner wall of the stopper groove 22, and the sectorial baffle plate 72 is made of a magnetic material.

[0066] Furthermore, when the regeneration furnace 1 and the cooling mechanism 4 are tilted overall toward the regeneration furnace 1, the docking pipe 71 moves to one end of the output port 21 due to the action of gravity. As the docking pipe 71 moves, a tooth groove that engages with the drive gear 714 is opened at a position close to the drive gear 714 on the inner wall of the smoke removal pipe 6, causing the drive gear 714 to rotate due to the action of the tooth groove. The rotating drive gear 714 rotates the transmission rod 715, and the transmission rod 715 rotates the transmission ring gear 716, and the rotating transmission ring gear 716 rotates the ball nut 713 via the driven gear 717, causing it to rotate.

[0067] Specifically, the threaded rod 722 and the ball nut 713 are matched, so that the rotating ball nut 713 drives the threaded rod 722, causing the threaded rod 722 to move toward the central axis of the ball nut 713. The threaded rod 722 then moves the sectorial baffle plate 72 toward the central axis of the ball nut 713, automatically opening the sectorial baffle plate 72. In this way, after the docking of the docking tube 71 and the output port 21 is completed, the docking tube 71 is in direct communication with the output port 21, ensuring that the smoke generated in the heating tube 2 can enter the smoke removal pipe 6 via the output port 21 and the docking tube 71.

[0068] After the regeneration of the activated carbon raw material in the heating tube 2 is completed, the overall tilt direction of the regeneration furnace 1 and the cooling mechanism 4 must be adjusted, i.e., the entire regeneration furnace 1 and the cooling mechanism 4 are tilted toward the regeneration furnace 1. In this way, the docking tube 71 moves away from the output port 21 due to gravity, and the rotation direction of the ball nut 713 is reversed as the docking tube 71 moves toward the end away from the output port 21. In this way, the ball nut 713 moves the sectorial baffle plate 72 to move in the opposite direction. In this way, when the docking tube 71 is completely inserted into the smoke removal pipe 6, the sectorial baffle plate 72 closes and seals the port at the end of the docking tube 71 closest to the output port 21. This ensures that the coal powder does not enter the docking tube 71 when the output port 21 transports the coal powder to the cold converter 41, reducing carbon loss and improving the activated carbon regeneration yield.
