Technical Field
[0001] The invention belongs to the technical field of activated carbon preparation, and particularly relates to a phase-separated physical activated carbon activation system. Background Art
[0002] At present, the field of activated carbon preparation is divided into two independent process flows: carbonization and activation. The activation process can be divided into physical, chemical and biological methods. With the continuous improvement of environmental protection requirements, the development prospects of physical methods are getting better and better.
[0003] The physical method can be specifically divided into: 1. Pyrolysis method: Pyrolysis of ordinary carbon at high temperature to generate more pores and a larger adsorption area. This is one of the most common activated carbon activation methods and is often used to produce advanced activated carbon in the fields of metal processing, chemical industry, food, medicine, environmental protection, etc. 2. Oxidation method: Oxidation treatment with air or high-purity oxygen to increase the pores and surface oxide content of activated carbon, thereby improving its adsorption performance. This method is often used to prepare activated carbon in the fields of air purification, oily wastewater treatment, etc.
[0004] However, in the prior art, most of the activation equipment related to physical methods have complex structures and cannot realize a series of operations from loading, activation, and discharging. The degree of mechanization is not high enough and the processing efficiency is low. Moreover, most of the equipment cannot separate normal activated carbon and fine powdered activated carbon, and needs to be achieved through subsequent screening and other structures, which undoubtedly further increases the processing cost and reduces the processing efficiency. Summary of the invention
[0005] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and to propose a phase-separated physical activated carbon activation system.
[0006] In order to achieve the purpose of the invention, the following technical solutions can be used:
[0007] A phase-separated physical activated carbon activation system comprises a cylindrical activation furnace body, wherein a cylindrical central combustion chamber is coaxially arranged in the middle of the activation furnace body, an annular activation channel is formed between the inner wall of the activation furnace body and the outer wall of the central combustion chamber, and the activation furnace body is provided with:
[0008] A material feeding and gas outlet structure, which is arranged at the upper end of the activation channel and includes a material passing gas outlet opening facing the activation channel in a clockwise direction;
[0009] The tail gas collection mechanism is located directly above the activation furnace body and is used to collect the activated tail gas discharged from the over-feed gas outlet;
[0010] A feeding mechanism, which is located on the side of the tail gas collecting mechanism and is used to transport the carbonized material to the over-gas outlet;
[0011] The main body rotating mechanism is used to drive the activation furnace body to rotate between its exhaust position, loading position and discharge position.

An atmosphere input mechanism is provided at the lower part of the activation channel for inputting corresponding activation atmosphere to ensure the normal activation reaction of the carbonized material. At the same time, the atmosphere has a certain flow velocity when input, and the output direction is consistent with or close to the circumferential direction of the activation channel at this position, so that the atmosphere flows circumferentially in the activation channel, driving the movement of the carbonized material, achieving the fluidization effect, promoting the contact between the carbonized material and the activation atmosphere, and promoting the activation reaction. Moreover, the output direction of the activation atmosphere is clockwise and counterclockwise.

[0017] The tail gas collection pipe is located at the upper end of the activation furnace body and can be installed through the corresponding bracket. It will not be expanded here. Its air inlet faces downward. When the activation furnace body rotates to the exhaust position, the air inlet and the feed outlet are opposite. A collection cover is provided on the activation furnace body. The outer end of the collection cover just docks with the feed outlet at this time, so as to achieve the effect of guiding the exhaust gas to the tail gas collection pipe.

[0020] In the above-mentioned phase-separated physical activated carbon activation system, the main body rotation mechanism includes at least two groups of support structures arranged at both ends of the activation furnace body, each group of the support structure includes two support seats symmetrically arranged on both sides of the activation furnace body, and the support seat is rotatably connected to a support roller on the side close to the activation furnace body, and the support roller is rollingly connected to the lower side wall of the activation furnace body, and a rotation drive assembly is provided between at least one of the support seats and the outer wall of the activation furnace body.
[0021] The activation furnace body is placed on the mounting position between the support seats. The support rollers between the support seats and the activation furnace body ensure the rotatability of the activation furnace body. The rotation drive assembly is used to specifically drive the rotation of the activation furnace body.
[0022] As an optimization, the rotation drive assembly includes transmission teeth circumferentially arranged on the side wall of the activation furnace body and a first reducer fixed on the support seat, and the output end of the first reducer is connected through gears and transmission teeth.
[0023] The rotation drive component specifically provides driving force through the first reducer, and the output end of the first reducer is engaged with the transmission teeth arranged on the activation furnace body to realize the transmission connection, wherein the transmission teeth are circumferentially arranged on the outer wall of the activation furnace body, and the effect of driving the activation furnace body to rotate is realized by the rotation of the first reducer.
[0024] In the above-mentioned phase-separated physical activated carbon activation system, the atmosphere input mechanism includes an air inlet pipe penetrating the lower side wall of the activation furnace body, the inner end of the air inlet pipe extends into the activation channel and is provided with a high-pressure nozzle, and the outer end extends out of the outer wall of the activation furnace body and is connected to the output end of the gas mixing component;
[0025] The high-pressure nozzle at least includes a first nozzle and a second nozzle. The direction of the first nozzle is adapted to the clockwise direction of the activation channel, and the direction of the second nozzle is adapted to the counterclockwise direction of the activation channel.
[0026] The air inlet pipe runs through the outer wall of the activation furnace body, and the outer end is connected to the gas mixing component for inputting the atmosphere such as water vapor required for activation. The inner end sprays the mixed gas through the high-pressure nozzle to provide the activation atmosphere, and also provides the air flow force required for the fluidization of the carbonized material. Two groups of high-pressure nozzles are arranged to realize the requirements of clockwise input and counterclockwise input, and the corresponding fluidization direction control is realized by connecting the first nozzle or the second nozzle.
[0027] In the above-mentioned phase-separated physical activated carbon activation system, the feeding mechanism includes a cylindrical feeding pipe horizontally arranged on the feeding rack, a feeding spiral is coaxially penetrated in the feeding pipe, the feeding spiral is rotatably connected to the feeding rack, a feeding hopper fixed on the feeding rack is provided at one end of the feeding pipe, the sleeve pipe at the lower end of the feeding hopper is connected to the end of the feeding pipe, a feeding port is opened on the side wall of the feeding pipe, the activation furnace body is located below the feeding port, and a feeding drive assembly is provided between the feeding spiral and the feeding rack.
[0028] The feeding pipe is arranged on the feeding rack in a horizontal arrangement. The feeding spiral is inserted in the feeding pipe and is rotatably connected to the feeding rack. The feeding drive assembly is used to drive the rotation of the feeding spiral. The carbonized material is fed from the feeding hopper at one end to one end of the feeding pipe. The material is then transported backward by the rotation of the feeding spiral. When the material is transported to the feeding port, the carbonized material is discharged from the carbonized material and output toward the main body of the activation furnace.
[0029] The feeding drive assembly comprises a feeding drive motor, which is fixed on the feeding frame, and the output end of the feeding drive motor is rotatably connected to the central axis of the feeding screw.
[0030] In the above-mentioned phase-separated physical activated carbon activation system, an annular partition is provided between the activation furnace body and the central combustion chamber, and the annular partition divides the activation channel into at least two axially distributed annular activation chambers, and each of the activation chambers is provided with the above-mentioned material outlet at the upper end and the above-mentioned atmosphere input mechanism at the lower part.
[0031] The activation channel is divided into multiple activation chambers by annular partitions. Each activation chamber is provided with corresponding material outlets and atmosphere input mechanisms, which can realize operations such as loading, activation and exhaust. However, each activation chamber is independent of each other and can be used to process different carbonized materials separately. In addition, since the heating degree in the middle section and both ends of the central combustion chamber may be different, that is, the temperature of each activation chamber may be different, there are also slight differences in the timing of loading. By adjusting the corresponding activation atmosphere input and compensating for the activation speed, the activation reaction process of each activation chamber can be specifically controlled to be close, ensuring that the activated carbon discharged from each activation chamber meets the activation standard when the activation furnace body rotates to the discharge position.
[0032] In the above-mentioned phase-separated physical activated carbon activation system, the feeding pipe is rotatably connected to the feeding rack, and at least two feeding ports are evenly distributed circumferentially on the side wall of the feeding pipe. The axial positions of the feeding ports correspond one-to-one to the passing air outlets. A switching drive assembly is provided between the feeding rack and the feeding pipe, which is used to drive the feeding pipe to rotate so that one of the feeding ports faces downward, and when the feeding air inlet corresponding to the feeding port enters the feeding position, a feeding channel is formed between the feeding port and the feeding air inlet; the sleeve pipe is rotatably connected to the end of the feeding pipe.
[0033] The feeding pipe is provided with a plurality of feeding ports adapted to the number of activation chambers, each feeding port corresponds to an activation chamber, and viewed from the axial direction, each feeding port is evenly distributed in the circumference, that is, when one of the feeding ports is facing downward, the other feeding ports are facing upward or to one side, and the carbonized material is transmitted forward at the lower part of the feeding pipe and will not be discharged from the feeding port that is not facing downward. Of course, the number of feeding ports should not be more than 4. The feeding pipe is rotatably connected to the feeding frame and can rotate circumferentially. The switching drive assembly is used to drive the rotation of the feeding pipe so that the corresponding feeding port is The feed port faces downward. When the activation furnace body is in the loading position, the feed port is connected with the corresponding loading air inlet to form a feeding channel. The carbonized material is pushed here by the loading spiral and will fall from the feed port to the loading air inlet and then enter the activation chamber to realize loading. By rotating the loading pipe to turn different feed ports downward, the loading action of different activation chambers can be realized. The structure is simple, in which the sleeve pipe of the loading hopper is rotatably connected to the end of the loading pipe, and the loading hopper can be fixed on the loading rack to ensure that it remains in an upward state.
[0034] As an optimization, a guide tube is provided on the outside of the feeding port, the upper end of the guide tube is fixed on the outer wall of the feeding pipe, and the lower end is just opposite to the corresponding feeding air inlet when the feeding port is facing downward. A feeding channel is formed in the guide tube, which is used to guide the carbonized material between the feeding port and the feeding air outlet.
[0035] As an optimization, the switching drive assembly includes a second reducer, which is fixed on the loading rack and has an output end connected to the loading tube in a transmission manner. The switching drive assembly drives the loading tube to rotate through the second reducer, wherein the second reducer is common knowledge, and its specific structure and corresponding connection details are not expanded.

The filtering structure includes a cyclone separator. A sealed material tank for collecting large-particle carbonized materials is provided below the cyclone separator. A bag filter assembly is provided on the exhaust port. The rear end of the bag filter assembly is connected to an external connection or to a heat exchange chamber of a steam boiler assembly.
[0038] The tail gas collection pipe is connected to the central combustion chamber, and the activated tail gas and fine powder carbonized material can be input into the central combustion chamber. On the one hand, the activated tail gas can be used as fuel to burn in the central combustion chamber to control the activation cost. On the other hand, after the fine powder carbonized material passes through the central combustion chamber, its temperature rises and becomes a high-temperature carrier. The central combustion chamber is connected to the gas mixing component. The high-temperature carrier and the high-temperature gas enter the activation channel after mixing, further increasing the activation temperature and ensuring that the carbonized material in the activation channel is heated evenly. Moreover, the gas mixing component is connected to the activation chamber through a separate output end, and the gas input of each activation chamber can be specifically controlled separately, which is convenient for coordinating the activation process of each activation chamber. In addition, a filtering structure is also connected to the tail gas collection mechanism, which can be used to filter the tail gas in the late stage of activation and then discharge it to protect the environment. In addition, the fine powder suspended carbonized material can be filtered out, and the larger particle size is deposited in the sealed material tank, while the smaller particle size is still suspended and filtered out by the bag filter component. The filtered gas is passed into the steam boiler component and discharged after participating in steam generation heat exchange, reducing the activation cost. The cyclone separator, bag filter assembly, sealed material tank and steam boiler assembly are common knowledge and will not be elaborated in detail.
[0039] In the above-mentioned phase-separated physical activated carbon activation system, a material receiving basket is provided below the activation furnace body, a cold material assembly is provided between the material receiving basket and the activation furnace, the inlet of the cold material assembly is connected with the material outlet when the activation furnace body rotates to the material discharging position, and the outlet of the cold material assembly is connected with the material receiving basket below.
[0040] A cold material assembly and a receiving basket are arranged below the main body of the activation furnace. The activated carbon after activation is cooled by the cold material assembly and then output to the receiving basket, thus realizing the output of the primary finished activated carbon. The inner cold material assembly and the receiving basket are common knowledge and will not be elaborated in detail.
[0041] Compared with the prior art, the present invention mainly has the following advantages:
[0042] 1. The activation system of the present invention is provided with a feed and gas outlet structure above the activation channel, and its feed outlet can be used to input the carbonized material to be activated, output the activated activated carbon, and discharge the activated tail gas and pyrolysis tail gas generated during the activation process. The tail gas collection mechanism is used to collect the gas discharged from the feed outlet, and the feeding mechanism is used to add the carbonized material to the activation channel to achieve the feeding effect. In addition, a main body rotation mechanism is also provided on the main body of the activation furnace, so that it can rotate between the exhaust position, the loading position and the discharge position. When in the exhaust position, the outer end of the feed outlet faces upward and docks with the air inlet of the tail gas collection mechanism; when in the loading position, the outer end of the feed outlet tilts upward and docks with the feeding port of the feeding mechanism; when in the discharge position, the feed outlet faces downward for dumping and discharging; only by rotating the main body of the activation furnace, the activation furnace main body can be switched between the three working states of activated exhaust, tilted loading and inverted discharging. An atmosphere input mechanism is provided at the lower part of the activation channel for inputting corresponding activation atmosphere to ensure the normal activation reaction of the carbonized material. At the same time, the atmosphere has a certain flow velocity when input, and the output direction is consistent with or close to the circumferential direction of the activation channel at this position, so that the atmosphere flows circumferentially in the activation channel, driving the movement of the carbonized material, achieving the fluidization effect, promoting the contact between the carbonized material and the activation atmosphere, and promoting the activation reaction. Moreover, the output direction of the activation atmosphere is clockwise and counterclockwise. When urged clockwise, the fluidization direction is consistent with the direction of the feed outlet, and the carbonized material is not easy to leak out of the feed outlet; when urged counterclockwise, the fluidization direction is opposite to the direction of the feed outlet, and at this time, the activation atmosphere can be discharged from the feed outlet with fine powder of carbonized material, thereby achieving the effect of separating the fine powder of carbonized material.
[0043] 2. The air inlet pipe runs through the outer wall of the activation furnace body, and the outer end is connected to the gas mixing component for inputting the atmosphere such as water vapor required for activation. The inner end sprays the mixed gas through the high-pressure nozzle to provide the activation atmosphere, and also provides the air flow force required for the fluidization of the carbonized material. Two groups of high-pressure nozzles are set to realize the requirements of clockwise and counterclockwise input, and the corresponding fluidization direction control is realized by connecting the first nozzle or the second nozzle.
[0044] 3. The activation channel is divided into multiple activation chambers by an annular partition. Each activation chamber is provided with a corresponding material outlet and atmosphere input mechanism, which can realize operations such as loading, activation exhaust, etc. However, each activation chamber is independent of each other and can be used to process different carbonized materials respectively. In addition, since the heating degree in the middle section and both ends of the central combustion chamber may be different, that is, the temperature of each activation chamber may be different, there are also slight differences in the time point of loading. By adjusting the corresponding activation atmosphere input and compensating the activation speed, the activation reaction process of each activation chamber can be specifically controlled to be close, ensuring that the activated carbon discharged from each activation chamber meets the activation standard when the activation furnace body rotates to the discharge position.
[0045] 4. The feeding pipe is provided with a plurality of feeding ports corresponding to the number of activation chambers, and each feeding port corresponds to an activation chamber. Viewed from the axial direction, each feeding port is evenly distributed circumferentially, that is, when one of the feeding ports is downward, the other feeding ports are upward or toward one side. The carbonized material is transmitted forward at the lower part of the feeding pipe and will not be discharged from the feeding port that is not downward. The feeding pipe is rotatably connected to the feeding rack and can rotate circumferentially. The switching drive assembly is used to drive the rotation of the feeding pipe so that the corresponding feeding port is downward. When the activation furnace body is in the feeding position, the feeding port is docked with the corresponding feeding air inlet to form a feeding channel.
[0046] 5. The tail gas collection pipe is connected to the central combustion chamber, and the activated tail gas and fine powder carbonized material can be input into the central combustion chamber. On the one hand, the activated tail gas can be used as fuel to burn in the central combustion chamber to control the activation cost. On the other hand, after the fine powder carbonized material passes through the central combustion chamber, its temperature rises and becomes a high-temperature carrier. The central combustion chamber is connected to the gas mixing component. The high-temperature carrier and the high-temperature gas enter the activation channel after mixing, further increasing the activation temperature and ensuring that the carbonized material in the activation channel is heated evenly. Moreover, the gas mixing component is connected to the activation chamber through a separate output end, and the gas input of each activation chamber can be specifically controlled separately, which is convenient for coordinating the activation process of each activation chamber. In addition, a filtering structure is also connected to the tail gas collection mechanism, which can be used to filter the tail gas in the late stage of activation and then discharge it to protect the environment. In addition, the fine powder suspended carbonized material can be filtered out, and the larger particle size is deposited in the sealed material tank, while the smaller one is still suspended and filtered out by the bag filter component. The filtered gas is passed into the steam boiler component and discharged after participating in steam generation and heat exchange, reducing the activation cost. BRIEF DESCRIPTION OF THE DRAWINGS

The feed outlet 31 is located between the bent end and the inner wall of the activation furnace body 1. The arc-shaped bending method reduces the interference and obstruction to the clockwise flow of the internal atmosphere. The outer end of the feed outlet 31 is connected to the outside of the furnace through the opening 32.

[0059] Specifically, the tail gas collection pipe 41 is located at the upper end of the activation furnace body 1, and is installed specifically through the corresponding bracket, with its air inlet 42 facing downward. When the activation furnace body 1 rotates to the exhaust position, the air inlet 42 is opposite to the material outlet 31. A collection cover 43 is provided on the activation furnace body 1, and the outer end of the collection cover 43 just docks with the material outlet 31 at this time, so as to achieve the effect of guiding the exhaust gas to the tail gas collection pipe 41, and the outer end of the collection cover 43 is an enlarged end, which has a better collection effect. The sealing skirt is annular, with the upper end fixed on the collection cover 43, and the lower end drooping, and is attached to the outer wall of the activation furnace body 1, so as to achieve the sealed docking of the material outlet 31 and the collection cover 43 when the activation furnace body 1 is in the exhaust position.
[0060] like Figure 1 , 2 As shown, the main body rotation mechanism 5 includes two groups of support structures 51 arranged at both ends of the activation furnace body 1, each group of support structures 51 includes two support seats 52 symmetrically arranged on both sides of the activation furnace body 1, and the support seat 52 is rotatably connected to a support roller on the side close to the activation furnace body 1, and the support roller is rollingly connected to the lower side wall of the activation furnace body 1, and a rotation drive component is provided between one of the support seats 52 and the outer wall of the activation furnace body 1. The rotation drive component includes a transmission tooth 53 circumferentially arranged on the side wall of the activation furnace body 1 and a first reducer fixed on the support seat 52, and the output end of the first reducer is transmission-connected to the transmission tooth 53 through a gear.
[0061] Specifically, the activation furnace body 1 is placed on the mounting position between the support seats 52, and the support rollers between the support seats 52 and the activation furnace body 1 ensure the rotatability of the activation furnace body 1, and the rotation drive assembly is used to specifically drive the activation furnace body 1 to rotate. The rotation drive assembly specifically provides driving force through the first reducer, and the output end of the first reducer is engaged with the transmission teeth 53 provided on the activation furnace body 1 to achieve transmission connection, wherein the transmission teeth 53 are circumferentially arranged on the outer wall of the activation furnace body 1, and the effect of driving the activation furnace body 1 to rotate is achieved through the rotation of the first reducer.
[0062] like Figure 2 , 3 As shown, the atmosphere input mechanism 6 includes an air inlet pipe 61 penetrating through the lower side wall of the activation furnace body 1, the inner end of the air inlet pipe 61 extends into the activation path 11, and is provided with a high-pressure nozzle 62, the outer end of which extends out of the outer wall of the activation furnace body 1 and is connected to the output end of the gas mixing component 22; the high-pressure nozzle 62 includes a first nozzle 63 and a second nozzle 64, the direction of the first nozzle 63 is adapted to the clockwise direction of the activation path 11, and the direction of the second nozzle 64 is adapted to the counterclockwise direction of the activation path 11.
[0063] Specifically, the air inlet pipe 61 passes through the outer wall of the activation furnace body 1, and the outer end is connected to the gas mixing assembly 22 for inputting the atmosphere such as water vapor required for activation. The inner end sprays the mixed gas through the high-pressure nozzle 62 to provide an activation atmosphere, and also provides the air flow force required for the fluidization of the carbonized material. Two groups of high-pressure nozzles 62 are arranged to achieve the requirements of clockwise input and counterclockwise input, and the corresponding fluidization direction control is achieved by connecting the first nozzle 63 or the second nozzle 64.
[0064] As an optimization of this embodiment, two annular partitions 12 are provided between the activation furnace body 1 and the central combustion chamber 21. The annular partitions 12 divide the activation channel 11 into three annular activation chambers 13 distributed axially. Each activation chamber 13 is provided with a feeding outlet 31 at the upper end, and an atmosphere input mechanism 6 at the lower part. The feeding mechanism 7 includes a cylindrical feeding pipe 71 which is horizontally arranged and rotatably connected to a feeding frame 73. A feeding screw 72 is coaxially penetrated in the feeding pipe 71. The feeding screw 72 is rotatably connected to the feeding frame 73. A feeding hopper 74 fixed to the feeding frame 73 is provided at one end of the feeding pipe 71. The sleeve pipe 77 at the lower end of the feeding hopper 74 can be relatively rotatably docked with the end of the feeding pipe 71. A feeding port 75 is provided on the side wall of the feeding pipe 71. The activation furnace body 1 is located below the feeding port 75. A feeding drive assembly is provided between the feeding screw 72 and the feeding frame 73. The feeding drive assembly includes a feeding drive motor, which is fixed on the feeding frame 73, and its output end is rotatably connected to the central axis of the feeding screw 72. Three feeding ports 75 are evenly distributed circumferentially on the side wall of the feeding tube 71, and the axial positions of the feeding ports 75 correspond to the over-feed air outlets 31 one by one. A switching drive assembly is provided between the feeding frame 73 and the feeding tube 71, which is used to drive the feeding tube 71 to rotate so that one of the feeding ports 75 faces downward, and when the feeding air inlet 42 corresponding to the feeding port 75 enters the feeding position, a feeding channel is formed between the feeding port 75 and the feeding air inlet 42.
[0065] Specifically, the activation channel 11 is divided into a plurality of activation chambers 13 by an annular partition 12, and each activation chamber 13 is provided with a corresponding material outlet 31 and an atmosphere input mechanism 6, which can realize operations such as loading, activation exhaust, etc., but each activation chamber 13 is independent of each other and can be used to process different carbonized materials respectively. In addition, since the heating degree in the middle section and the two ends of the central combustion chamber 21 may be different, that is, the temperature of each activation chamber 13 may be different, and there are slight differences in the time point of loading, by adjusting the corresponding activation atmosphere input and compensating the activation speed, the activation reaction process of each activation chamber 13 can be specifically controlled to be close, ensuring that the activated carbon discharged from each activation chamber 13 meets the activation standard when the activation furnace body 1 rotates to the discharge position. The feeding pipe 71 is arranged on the feeding rack 73 in a horizontal manner. The feeding screw 72 is inserted into the feeding pipe 71 and is rotatably connected to the feeding rack 73. The feeding drive assembly is used to drive the rotation of the feeding screw 72. The carbonized material is fed from the feeding hopper 74 at one end to one end of the feeding pipe 71. The material is then transported backward by the rotation of the feeding screw 72. When it is transported to the position of the feeding port 75, the carbonized material is discharged from the carbonized material and output toward the activation furnace main body 1. The feeding pipe 71 is provided with a plurality of feeding ports 75 corresponding to the number of the activation chambers 13, and each feeding port 75 corresponds to the activation chamber 13. From the axial direction, each feeding port 75 is evenly distributed in the circumferential direction, that is, when one of the feeding ports 75 is facing downward, the other feeding ports 75 are facing upward or toward one side, and the carbonized material is transported forward at the lower part of the feeding pipe 71 and will not be discharged from the feeding port 75 that is not facing downward. The feeding pipe 71 is rotatably connected to the feeding frame 73 and can rotate circumferentially. The switching drive assembly is used to drive the rotation of the feeding pipe 71 so that the corresponding feeding port 75 is facing downward. When the furnace body 1 is in the loading position, the feeding port 75 is connected with the corresponding loading air inlet 42 to form a feeding channel. The carbonized material is pushed here by the feeding screw 72 and will fall from the feeding port 75 to the loading air inlet 42 and then enter the activation chamber 13 to achieve loading. By rotating the loading tube 71 to turn different feeding ports 75 downward, the loading action of different activation chambers 13 can be achieved. The structure is simple, wherein the sleeve pipe 77 of the loading hopper 74 is rotatably connected to the end of the loading tube 71, and the loading hopper 74 can be specifically fixed on the loading frame 73 to ensure that it remains in an upward state. The switching drive component includes a second reducer, which is fixed on the loading frame 73, and its output end is transmission-connected to the loading tube 71. The switching drive component drives the loading tube 71 to rotate through the second reducer.
[0066] As a further optimization, a guide tube 76 is provided on the outside of the feeding port 75, the upper end of the guide tube 76 is fixed on the outer wall of the feeding pipe 71, and the lower end is just opposite to the corresponding feeding air inlet 42 when the feeding port 75 is facing downward. A feeding channel is formed in the guide tube 76, which is used to guide the carbonized material between the feeding port 75 and the feeding outlet.
[0067] like Figure 1As shown, the exhaust gas collecting pipe 41 of the exhaust gas collecting mechanism is connected to the central combustion chamber 21 by a pipeline, which is used to input the activated exhaust gas or fine powder carbonized material into the central combustion chamber 21. The central combustion chamber 21 is connected to the first input end pipeline of the gas mixing component 22, and the second input end of the gas mixing component 22 is also connected to the steam boiler component 23. The heat exchange chamber of the steam boiler component 23 is also connected to the central combustion chamber 21 pipeline. The gas mixing component 22 includes at least two output ends, which are respectively connected to each activation cavity 13 of the activation furnace body; the exhaust gas collecting mechanism 4 is also connected to a filtering structure 78 for filtering out fine powder carbonized material in the exhaust gas, and the filtering structure 78 includes a cyclone separator 81, and a sealed material tank 82 for collecting large-particle carbonized material is provided below the cyclone separator 81, and a bag filter component 83 is provided on the exhaust port, and the rear end of the bag filter component 83 is connected to an external connection or to the heat exchange chamber of the steam boiler component 23.
[0068] Specifically, the exhaust gas collecting pipe 41 is connected to the central combustion chamber 21, and the activated exhaust gas and fine powder carbonized material can be input into the central combustion chamber 21. On the one hand, the activated exhaust gas can be burned as fuel in the central combustion chamber 21 to control the activation cost. On the other hand, after the fine powder carbonized material passes through the central combustion chamber 21, its temperature increases and becomes a high-temperature carrier. The central combustion chamber 21 is connected to the gas mixing component 22. The high-temperature carrier and the high-temperature gas enter the activation channel 11 after mixing, which further increases the activation temperature and ensures that the carbonized material in the activation channel 11 is heated evenly. Moreover, the gas mixing component 22 is connected to the activation chamber 13 through a separate output end, and the gas input situation of each activation chamber 13 can be specifically controlled respectively, so as to coordinate the activation process of each activation chamber 13. In addition, a filtering structure 78 is also connected to the exhaust gas collection mechanism 4, which can be used to filter the exhaust gas before discharging it in the later stage of activation to protect the environment. In addition, fine powder suspended carbonized materials can be filtered out, and larger particles are deposited in the sealed material tank 82, while smaller particles remain suspended and are filtered out by the bag filter assembly 83. The filtered gas is passed into the steam boiler assembly 23 and discharged after participating in steam generation and heat exchange, thereby reducing the activation cost.
[0069] As an optimization of this embodiment, a receiving basket is provided below the activation furnace body 1, and a cold material assembly is provided between the receiving basket and the activation furnace. The inlet of the cold material assembly docks with the material outlet 31 of the activation furnace body 1 when the activation furnace body 1 rotates to the material discharging position, and the outlet of the cold material assembly docks with the receiving basket below. A cold material assembly and a receiving basket are provided below the activation furnace body 1, and the activated carbon after activation is cooled by the cold material assembly and output to the receiving basket, thereby realizing the output of the primary finished activated carbon.
[0070] For illustration, the bracket, the first reducer, the feeding drive motor, the switching drive assembly, the cold material assembly, and the material receiving basket are not specifically shown in the figure.
[0071] Specific working principle: During startup, the fuel supply assembly inputs fuel into the central combustion chamber 21 for combustion, and the combustion generates heat to raise the temperature of the activation channel 11 to the activation temperature.
[0072] When loading, the first reducer is activated, the activation furnace body 1 rotates a certain angle to enter the loading position, and its opening 32 is tilted upward. The second reducer is activated to turn the loading pipe 71 to the feeding port 75 closest to the loading hopper 74 downward, and the carbonized material is poured from the loading hopper 74. The loading screw 72 rotates under the drive of the loading drive motor to transport the carbonized material to the rear. The carbonized material falls at the first feeding port 75, passes through the guide pipe 76 and the opening 32, and enters the corresponding activation chamber 13 from the material outlet 31. After the activation chamber 13 is fully loaded, the second reducer is activated again to make the second feeding port 75 downward, and the second and third activation chambers 13 are loaded in the same way. After all the loading is completed, the first reducer is reversed, and the activation furnace body 1 is reset to the exhaust position.
[0073] During activation, the high-temperature flue gas in the central combustion chamber 21 exchanges heat in the steam boiler assembly 23, and the generated steam and high-temperature flue gas are mixed through the gas mixing assembly 22 and output from its output end. The mixed gas is ejected through the high-pressure nozzle 62, and the first nozzle 63 is ejected in the early stage of the reaction. The activated atmosphere and the carbonized material are fluidized and move in the activation chamber 13, and an activation reaction occurs. After a certain period of time, the first nozzle 63 is closed, and the second nozzle 64 is opened, and the flow rate is reduced at the same time. The fine powdered carbonized material is discharged from the material outlet 31 along with the activated atmosphere and enters the central combustion chamber 21, where activated tail gas such as CO is burned, and the temperature of the fine powdered carbonized material increases to become a high-temperature carrier, and then output to the gas mixing assembly 22, and enters the activation chamber 13 again after mixing, to increase and equalize the temperature in the activation chamber. In the late stage of activation, the connection between the tail gas collection pipe 41 and the central combustion chamber 21 is closed, and the fine powder carbonized material and tail gas enter the cyclone separator 81 from the material outlet 31. The carbonized material with large particle size sinks to the sealed material tank 82 for collection, and the small particle size is filtered out and separated by the bag filter assembly. The filtered gas enters the steam boiler assembly 23 and is finally discharged after heat exchange.
[0074] After activation is completed, the first reducer is activated to rotate the activation furnace body 1 to the discharge position, and the activated activated carbon is poured out from the material outlet 31, and finally enters the receiving basket after being cooled by the cold material component, thereby realizing the output of the primary finished activated carbon. After pouring, the first reducer is reversed to reset.
[0075] The above process completes one wave of carbonized material activation treatment, and subsequent loading, activation and discharging can be carried out in the same way.
