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 that produces activated carbon is approximately 850℃~950℃, and the activated carbon needs to be kept warm in the regeneration furnace at a temperature of 850℃~950℃. A large amount of smoke is generated during the regeneration process of the activated carbon raw material, but the smoke exhaust path and the carbon powder discharge path when the regeneration furnace completes the regeneration process are the same. During the discharge process, the temperature of the carbon powder reaches 850℃, and when it is discharged at a high temperature, it must be cooled by blocking oxygen quickly. Otherwise, the powdered activated carbon will burn out and there is a risk of deflagration, so the regeneration furnace needs to 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, the cooling effect is required to make the coal powder supersaturated, which requires that the contact time of the coal powder with the cooling mechanism is long enough. Thus, the discharge speed of the coal powder is limited and the loss of the cooling mechanism is increased, which increases the production cost of the coal powder. Summary of the Invention

[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 thereof, a screw rod provided therein and operatively connected to the feed motor, and a feed chute provided at its top surface near the discharge port of the buffer silo.

[0014] According to a further embodiment of the present invention, the automatic docking tube includes a docking tube having a plurality of sector 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 side of the docking tube has a plurality of arc-shaped protrusions evenly distributed thereon, 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 an end face of one end of the docking tube close to the sector baffle plate, a threaded rod which engages with the ball nuts is fixedly connected to the side of the sector baffle plate, a stop collar is provided at the tip position of the side of the sector baffle plate, and a limit lever which engages with the stop collar is fixedly connected to a position close to the stop collar on the inner wall of the docking tube.

[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 for engaging 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 tube is provided between the regeneration furnace and the cooling mechanism, which realizes a hermetically flexible connection between the regeneration furnace and the cooling mechanism, and ensures that the activated carbon in the heating tube is in a sealed state under high temperature, thus preventing oxygen in the external environment from entering the heating tube, reducing the carbon loss during the regeneration process of the activated carbon, and improving the yield of regenerated carbon powder.

[0019] In the present invention, the regeneration furnace and the cooling mechanism are both installed on the top surface of the base, so that the inclination angles of the regeneration furnace and the cooling mechanism can be adjusted simultaneously by adjusting the inclination angle of the base. The hydraulic cylinder tilts the base toward the regeneration furnace, that is, the height of the regeneration furnace is smaller than the height of the cooling mechanism. In this way, the automatic docking tube automatically slides to the end close to the heating tube under the action of its own gravity, and contacts the outlet end of the heating tube, ensuring that the smoke removal pipe communicates with the heating tube. In this way, the smoke generated in the heating tube can be transported to the smoke removal pipe through the automatic docking tube, and the smoke removal pipe discharges the smoke through the high-temperature smoke tube, realizing the discharge of smoke, and since the height of the regeneration furnace is smaller than the height of the cooling mechanism, the end of the heating tube close to the automatic docking tube is higher than the end close to the material supply mechanism, which can prevent 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 platform toward the cooling mechanism, that is, the height of the regeneration furnace is greater than the height of the cooling mechanism. In this way, the automatic docking tube automatically slides to the end close 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 released from contact. The inner wall of the outlet end of the heating tube is provided with a spiral plate. When the heating tube is driven to rotate by an external force, the end of the heating tube close to the smoke removal pipe is lower than the other end, so that the regenerated coal powder in the heating tube flows to the outlet end of the heating tube and is discharged to the cooling mechanism by the action of the spiral plate, realizing the separation of the smoke and the regenerated coal powder, preventing the residual smoke from being mixed into the regenerated coal powder, and improving the purity of the regenerated coal powder.

[0021] In the present invention, the 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 larger 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 temperature of the coal powder to a set value, which not only ensures the flow rate of the coal powder, but also ensures 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, and the powdered activated carbon oxidation-free continuous regeneration cooling production line is very suitable for large-scale production and its automated production.

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

[0025] [Example 1] As shown in Figures 1 and 2, the present invention discloses a powdered activated carbon non-oxidizing continuous regenerative cooling production line. The production line specifically includes a regenerative furnace 1 with a heating tube 2 inside that uses electric heating, natural gas or fuel heating. Electric heating uses an electric heating element with a silicon carbide rod as a priority, and the silicon carbide rod has the advantages of good heating effect, fast temperature rise, and easy maintenance and replacement. A cooling mechanism 4 is provided 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 pedestal 3 is provided at the bottom of the regenerative furnace 1 and the cooling mechanism 4, and a hydraulic cylinder 31 is attached to the bottom of the pedestal 3 to control the inclination angle of the regenerative furnace 1 and the cooling mechanism 4. The cooling mechanism 4 is equipped with a cooling control module that obtains 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 inclination angle and rotation speed of the cooling mechanism 4, constructs a computer linear regression model, and predicts the inclination 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 tube 9 and the other end of which is provided with a movable automatic docking tube 7.

[0027] The heating tube 2 is inserted horizontally into the central axis of the regeneration furnace 1. The heating tube 2, which uses electric heating, natural gas, or fuel heating, 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 needs to be kept warm for 40 to 60 minutes, thereby removing moisture and organic matter in the activated carbon inside the heating tube 2.

[0028] A sealed tube 8 is provided between the regeneration furnace 1 and the cooling mechanism 4, so that a hermetically flexible connection between the regeneration furnace 1 and the cooling mechanism 4 is realized, and the activated carbon in the heating tube 2 is ensured to be in a sealed state under high temperature. In this way, the oxygen in the external environment can be prevented from entering the heating tube 2, and the carbon loss during the regeneration process of the activated carbon can be reduced.

[0029] The hydraulic cylinder 31 drives the pedestal 3 with a hydraulic rod, and can adjust the inclination 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, by adjusting the inclination angle of the pedestal 3, the inclination angles of the regeneration furnace 1 and the cooling mechanism 4 can 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, that is, 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 realizing the discharge of smoke. Furthermore, since 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, which prevents the activated carbon raw material in the heating tube 2 from leaking into the automatic docking tube 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, that is, the height of the regeneration furnace 1 is greater than the height of the cooling mechanism 4. In this way, the automatic docking tube 7 automatically slides to the end close 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 released from contact. As shown in FIG. 2, a spiral plate is provided on the inner wall of the outlet end of the heating tube 2, and when the heating tube 2 is driven to rotate by an external force, the end of the heating tube 2 close to the smoke removal pipe 6 is lower than the other end, so that the regenerated carbon powder in the heating tube 2 flows to the outlet end of the heating tube 2 and is discharged to the cooling mechanism 4 by the action of the spiral plate, and the cooling mechanism 4 can perform a cooling process on the carbon powder.

[0032] As shown in FIG. 3, the cooling mechanism 4 includes a cold converter 41 having a first support roller 42 and a second support roller 43 at both ends of its bottom surface, and 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 at the top position close to the first support roller 42 on the top surface of the cold converter 41, and a second tire 431 is provided at the top position close to the second support roller 43 on the top surface of the cold converter 41, and the power of the converter motor 44 is transferred to the cold converter 41 by a gear, so that the cold converter 41 can be rotated. Since the cold converter 41 and the heating tube 2 are connected by a sealed tube 8, the rotating cold converter 41 can move the heating tube 2 by the sealed tube 8 to rotate synchronously. Since a spiral plate is provided on the inner wall of the outlet end of the heating tube 2, the delivery of the activated carbon inside the heating tube 2 can be controlled by controlling the rotation direction of the heating tube 2.

[0034] As shown in Figures 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 coal powder pipe 46 and a water-cooled groove 47 are opened inside the cold converter 41. The number of coal powder pipes 46 is multiple and threaded inside. The coal powder pipes 46 are uniformly distributed at the edge positions inside the cold converter 41, and the water-cooled pipe 45 communicates with the water-cooled groove 47. The water-cooled pipe 45 includes a water inlet pipe 451 having a water outlet pipe 452 on the inside, a water inlet port 453 at one end, and a docking pipe 455 at the other end. 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] In addition, the screw groove opened 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 plays a role in guiding the coal powder, that is, increasing 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 the cold water source in the external environment through the water inlet port 453, so that the cold water source can deliver cooling water to the water inlet pipe 451, and the water inlet pipe 451 delivers cooling water to the water cooling groove 47 through the docking pipe 455, and 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 the coal powder. After the cooling water in the water cooling groove 47 absorbs heat, it 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 to realize the circulation of the cooling water.

[0036] As shown in FIG. 5, the temperature t of the coal powder in the coal powder tube 46 is measured at both ends and the middle position of the coal powder tube 46. 入 , t 中 and t 出 Temperature sensors are provided for monitoring 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 tube 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 tube 46, and t 出 is the temperature of the coal powder at the port at one end of the coal powder tube 46 away from the cold converter 41, and the temperature sensor is t 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 the point where 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 travel half the distance in the coal particle tube 46, i.e., the temperature to which the coal particles cool in half the time. 入 When the temperature of the coal powder is high, the coal powder tube 46 must absorb more heat from the coal powder to complete the cooling for the coal powder.

[0039] A rotation speed sensor is attached to one end of the cold converter 41 close to the converter motor 44 for monitoring the rotation speed n of the cold converter 41, converting the rotation speed n into an electric signal and transmitting 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 electric signal, and transmit it to the cooling control module.

[0041] The cooling control module constructs a computer linear regression model according to 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. In addition, 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 t, t and t of the coal powder in the coal powder tube 46 are obtained by temperature sensors at both ends and the middle position of the coal powder tube 46. Multiple sets of the rotation speed n of the cold converter 41 and the tilt angle a of the cold converter 41 can be set as necessary, and the temperatures t of the coal powder in the coal powder tube 46 corresponding to the multiple sets 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 by a computer linear regression model.

[0043] The cooling control module is preset by manual input. 出(プリ) For example, t 出(プリ) = 40℃. The cooling control module also uses a temperature sensor to 入 and 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] In the case where the rotation speed n of the cold converter 41 does not change, that is, the rotation speed n of the cold converter 41 is maintained so as not to change. 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 t 出(プリ) This is the tilt angle required when predicting that the rotation speed in the cold converter of the base 3 is n based on the above. 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 中 Monitors the preset t 出(プリ) Based on this, 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; and the formula "a プリ =[t 出(プリ) -(A×t 入 +B×t 中 The inclination angle a obtained by "(a)=(b) / D" is the optimal inclination angle for cooling the coal powder temperature to the set value, and ensures the flow rate of the coal powder as well as 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, and the powdered activated carbon oxidation-free continuous regeneration and cooling production line is very suitable for large-scale production and its 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 on top, a buffer silo 55 mounted on the track 52, and a feed spiral tube 56 mounted at the discharge port of the buffer silo 55. A running mechanism 58 that matches with the track 52 is provided at the bottom of the buffer silo 55. A feed bin 53 is provided at the top of the track 52, a conveyor belt 54 is provided at the discharge port of the feed bin 53, one end of the conveyor belt 54 away from the feed bin 53 is provided at the top of the buffer silo 55, and rolling wheels 57 that are mutually engaged with the track 52 are provided at the bottom of the feed bin 53 and the buffer silo 55.

[0049] The position between the feed bin 53 and the buffer silo 55 is fixed, and both are mounted on the track 52 by the rolling wheels 57, which allow them to run freely horizontally on the track 52. The feed bin 53 is used to feed the activated carbon raw material, which falls onto the top of the conveyor belt 54 through the discharge port at the bottom of the feed bin 53 and automatically disperses when it hits the conveyor belt 54, thus realizing the effect of laying the activated carbon raw material flat. The conveyor belt 54 then transports the flatly 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 the 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 dynamically connected to the feed motor 564 provided inside thereof, and a feed chute 563 opened at a location on the top surface thereof near the discharge port of the buffer silo 55.

[0051] The feed motor 564 rotates the screw rod 565 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, moving the activated carbon raw material inside the feed pipe 561, thereby transporting the activated carbon raw material.

[0052] 9 and 10, the traveling mechanism 58 includes a reducer 581 having a power input end connected to a drive motor 582 and a power output end connected to a drive shaft 583, a bearing box 584 is nested in the center position on the side of the drive shaft 583, and a built-in drive wheel 585 that matches the truck 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 and the track 52 are matched. In this way, the rotating built-in driving wheel 585 moves the feed bin 53 and the buffer silo 55 to travel freely in the horizontal direction 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 according to 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, 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 obtain 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 1 / 2 of the cavity of the heating tube 2, ensure that the activated carbon raw material is evenly introduced, and also reserve space for the smoke to circulate, so that the activated carbon raw material can normally carry out the regeneration process.

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

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

[0061] Furthermore, 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 can be exactly fitted 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, while matching with the sectorial baffle plate 72 to ensure the sealing of the docking portion between the docking tube 71 and the output port 21, and prevent smoke from leaking when the smoke is transported.

[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] In addition, since the arc-shaped protrusion 711 exceeds the side surface of the docking tube 71, when the docking tube 71 slides on 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 very small. This greatly reduces the friction force between the side surface of the docking tube 71 and the inner wall of the smoke detergency pipe 6, and the docking tube 71 can slide smoothly on the inner wall of the smoke detergency pipe 6.

[0064] As shown in FIG. 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 which 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 which 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 driving gear 714 is provided at one end of the side of the docking tube 71 away from the sector baffle plate 72, and a tooth groove is provided at a position close to the driving gear 714 on the inner wall of the smoke removal pipe 6 to engage with the driving gear 714, a transmission rod 715 is meshed with the inside of the driving gear 714, a transmission ring gear 716 is meshed with one end of the transmission rod 715 away from the driving gear 714, a driven gear 717 is meshed with one side of the transmission ring gear 716 away from the transmission rod 715, and the driven gear 717 is meshed with the side of the ball nut 713. A negative pressure motor is connected to one end of the high-temperature smoke pipe 9 away from the cooling mechanism 4, a permanent magnet 23 is provided on the inner wall of the stopper groove 22, and the sector baffle plate 72 is made of a magnetic material.

[0066] In addition, when the regenerator 1 and the cooling mechanism 4 are inclined toward the regenerator 1 as a whole, the docking pipe 71 moves to one end of the output port 21 due to the action of gravity. In the process of the docking pipe 71 moving, a tooth groove that engages with the driving gear 714 is opened at a position close to the driving gear 714 on the inner wall of the smoke removal pipe 6, so that the driving gear 714 rotates due to the action of the tooth groove. The rotating driving gear 714 rotates the transmission rod 715, the transmission rod 715 rotates the transmission ring gear 716, and the rotating transmission ring gear 716 moves the ball nut 713 by the driven gear 717 to rotate it.

[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 to move the threaded rod 722 toward the central axis of the ball nut 713. The threaded rod 722 moves the sector baffle plate 72 toward the central axis of the ball nut 713, so that the sector baffle plate 72 is automatically opened. In this way, after the docking of the docking tube 71 and the output port 21 is completed, the docking tube 71 is directly connected to the output port 21, and it is ensured that the smoke generated in the heating tube 2 can enter the smoke removal pipe 6 through 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, that is, the entire regeneration furnace 1 and the cooling mechanism 4 are tilted toward the regeneration furnace 1. In this way, the docking tube 71 is separated from the output port 21 by the action of gravity, and the rotation direction of the ball nut 713 is reversed in the process of the docking tube 71 moving to the one end away from the output port 21. In this way, the ball nut 713 moves the sector 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 sector baffle plate 72 closes to seal the port at one end of the docking tube 71 close to the output port 21, and when the output port 21 transports the coal powder to the cold converter 41, the coal powder is ensured not to enter the docking tube 71, which can reduce carbon loss and improve the regeneration yield of activated carbon.
