Description

Technical Field

[0001] The invention belongs to the technical field of activated carbon production, and in particular relates to activated carbon production equipment integrating carbonization and activation. Background Art

[0002] Activated carbon is a specially treated carbon. Organic raw materials (fruit shells, coal, wood, etc.) are heated in an airtight condition to reduce non-carbon components (this process is called carbonization), and then react with gas to erode the surface and produce a structure with developed micropores (this process is called activation). Since the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is point erosion, the surface of activated carbon has countless tiny pores. The diameter of the micropores on the surface of activated carbon is mostly between 2 and 50nm. Even a small amount of activated carbon has a huge surface area. The surface area of ​​each gram of activated carbon is 500 to 1500m 2 Almost all applications of activated carbon are based on this characteristic of activated carbon.

[0003] At present, most of the existing equipment for the production of activated carbon realizes the preparation of activated carbon from pre-treated raw materials in steps through independent carbonization equipment and activation equipment, and additional equipment and processes for transferring carbonized materials are required in between, so this production method is inefficient.

[0004] As an improvement and upgrade, some integrated equipment has been introduced. However, most of the integrated equipment still carries out carbonization or activation reactions separately and sequentially, and cannot carry out flow-line processing of carbonization or activation at the same time. The processing efficiency needs to be further improved, and it is unable to accurately control the corresponding reaction temperature. The quality of activated carbon needs to be further improved. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems in the prior art and to provide an activated carbon production device integrating carbonization and activation.

[0006] In order to achieve the purpose of the invention, the following technical solutions can be used:

[0007] An activated carbon production device integrating carbonization and activation comprises a square furnace body, wherein the upper end of the furnace body is provided with a feeding port, the lower end of the furnace body is provided with a discharging port, a working chamber is formed between the feeding port and the discharging port, and the furnace body comprises:

[0008] A carbonization chamber, wherein a carbonization material tray is provided in the carbonization chamber, and a carbonization material discharge mechanism is provided between the carbonization material tray and the furnace body for driving the carbonization material tray to remain horizontal or rotate and tilt to one side, wherein the carbonization material tray has a horizontal carbonization reaction position and two carbonization material discharge positions tilted to the left or right side;

[0009] An activation chamber, wherein at least two activation trays are provided in the activation chamber and are respectively connected to the bottom of the carbonization material discharge position. An activation material discharge mechanism is provided between the activation material tray and the furnace body for driving the activation material tray to maintain a horizontal state or to rotate and tilt. The activation material tray has a horizontal activation reaction position and an activation material discharge position tilted to one side, and the discharge port is located below the activation material discharge position.

[0010] A diaphragm mechanism, which separates the working chamber into a carbonization chamber at an upper position and an activation chamber at a lower position, and the diaphragm mechanism includes an elastic reset component which opens to form a material discharge channel when the carbonization material tray rotates to the carbonization material discharge position, and keeps the material discharge channel closed when in the carbonization reaction position;

[0011] A carbonization temperature control mechanism and an activation temperature control mechanism are respectively arranged between the carbonization chamber and the activation chamber and the furnace body;

[0012] The activation chamber is connected with an activation atmosphere supply component.

[0013] The activated carbon production equipment of the present invention is used to realize the integrated production of raw material-carbonized material-activated carbon. The raw material is fed into the carbonized material tray in the carbonization chamber from the feeding port. The carbonization temperature control mechanism maintains the temperature of the carbonization chamber at the temperature required for carbonization. The raw material undergoes carbonization reaction on the carbonized material tray. After the carbonization is completed, the carbonization unloading mechanism rotates the carbonized material tray to one side, and the carbonized material tray enters the carbonization unloading position, and during the entry process, the diaphragm mechanism opens the unloading channel, and the carbonized material enters the activation material tray in the activation chamber from the unloading channel. The activation temperature control mechanism controls the activation chamber at the required temperature for activation, and the activation atmosphere supply component keeps the activation chamber at a suitable activation atmosphere. The carbonized material is activated under suitable temperature and atmosphere conditions to form activated carbon. After the activation is completed, the activation unloading mechanism drives the activation material tray to rotate, so that the activation material tray enters the activation unloading position to pour out the activated carbon, and the activated carbon is output from the discharge port below, completing the integrated production of raw materials to activated carbon. Of course, the raw materials here are subjected to corresponding pretreatment. In specific production, the time required for the carbonization process is shorter than that required for the activation process. In order to improve production efficiency, the carbonization tray is tilted to the left or right to form two activation material discharge positions, and a carbonization tray is docked under each activation material discharge position to reduce the idle waiting time of the activation tray and the carbonization tray. In addition, the activation temperature control mechanism and the carbonization temperature control mechanism control the temperature environment of the activation chamber and the carbonization chamber respectively, optimize the reaction effect of carbonization and activation, and improve product quality. Moreover, the diaphragm mechanism separates the carbonization chamber and the activation chamber to avoid or reduce the activation atmosphere of the activation chamber from entering the carbonization chamber, reduce the temperature interference between the two and the reaction atmosphere interference, and further ensure product quality.

[0014] As an optimization, the discharge port and the feeding port are respectively provided with a switch door assembly, which keeps the discharge port and the feeding port closed when no feeding or discharging is required, thereby reducing the impact of the external environment on the heat or reaction atmosphere of the working chamber. The switch door assembly is common knowledge and will not be elaborated in detail.

[0015] In the above-mentioned activated carbon production equipment with integrated carbonization and activation, the carbonization feeding mechanism includes a first rotating shaft and a carbonization feeding motor, the first rotating shaft is rotatably connected to the side wall of the furnace body, and at least one end passes through the outer wall of the furnace body and is transmission-connected to the output end of the carbonization feeding motor; the cross-section of the carbonization material tray is an arc or trapezoid with a larger upper part and a smaller lower part, a carbonization receiving cavity is formed on the carbonization material tray, and the first rotating shaft is fixed under the carbonization material tray.

[0016] The carbonization material tray is fixed on the first rotating shaft, and the carbonization unloading motor drives the rotation of the carbonization material tray, thereby realizing the switching of the carbonization material tray between the carbonization reaction position and the carbonization unloading position. The structure is simple and the control is stable. The cross-section of the carbonization material tray is arc-shaped or trapezoidal, which prevents the material from falling out from both sides. At the same time, it also makes it easy for the raw materials to be poured out completely when the carbonization material tray rotates and tilts. The dumping effect can be achieved by rotating a certain acute angle, reducing the possibility of carbonized material retention. Of course, the specific shape is not limited to arc-shaped or trapezoidal, and other similar shapes are also acceptable.

[0017] As an optimization, the carbonized material tray is in a straight line shape, with baffles at both ends to form a trough structure, and the length direction of the first rotating shaft is consistent with the length direction of the carbonized material tray.

[0018] In the above-mentioned activated carbon production equipment with integrated carbonization and activation, a material-shifting structure for shifting materials is provided above the carbonization material receiving chamber, and the material-shifting structure includes a material-shifting plate rotatably connected to the inner wall of the furnace body through a material-shifting shaft, and the material-shifting plate, the material-shifting shaft and the first shaft are all arranged in the same direction, and at least one end of the material-shifting shaft passes through the side wall of the furnace body and is transmission-connected to the output end of the material-shifting driving motor, and there is a material passing gap between the lower end of the material-shifting plate and the inner surface of the carbonization material receiving chamber; a baffle with an inverted V-shaped cross-section is provided between the material-shifting structure and the feeding port, and both ends of the baffle are fixed to the inner wall of the furnace body, and the baffle and the material-shifting shaft are consistent in length direction and are located above the material-shifting shaft.

[0019] The material-shifting structure is used to shift the material evenly to avoid the material piling up like a mountain on the carbonizing material tray, so that the material is heated evenly and the carbonization effect is optimized. The material-shifting plate is fixed on the material-shifting shaft. The material-shifting drive motor drives the material-shifting shaft to rotate and then realizes the rotation of the material-shifting plate to shift the accumulated material evenly. The material-passing gap is the expected thickness to spread the material evenly on the carbonizing material tray. When the carbonizing material tray is about to rotate to discharge the material, the material-shifting plate rotates to the other side to avoid affecting the carbonizing material tray from entering the carbonization discharge position. As an optimization, the material-shifting structure is located in the middle and upper part of the carbonization material receiving cavity, which ensures the uniformity of the material shifting and avoids the different effects on the carbonizing material tray from entering any carbonization discharge position. The baffle is arranged above the material-shifting shaft. On the one hand, it is used to prevent the raw materials from sticking to the material-shifting shaft. On the other hand, its upper end forms a sharp angle, which can guide the material to both sides when it is put in, reducing the stacking height on the carbonizing material tray to a certain extent.

[0020] In the above-mentioned activated carbon production equipment with integrated carbonization and activation, the cross-section of the activation material tray is an arc or trapezoid that is larger at the top and smaller at the bottom. An activation material receiving cavity is formed in the activation material tray. A horizontally arranged second rotating shaft is fixedly provided under the carbonization material tray. Both ends of the second rotating shaft are rotatably connected to the side walls of the furnace body, and at least one end passes through the outer wall of the furnace body and is transmission-connected to the output end of the activation feeding motor.

[0021] The activation tray is similar to the carbonization tray and is also arc-shaped or trapezoidal. Of course, its width is about half of the carbonization tray. The carbonized material falls into the activation material receiving chamber for activation reaction. The activation unloading motor drives the activation tray to rotate through the second shaft, so that the activation tray switches between the activation reaction position and the activation unloading position. The structure is simple and the control is stable.

[0022] In the above-mentioned activated carbon production equipment with integrated carbonization and activation, the partition mechanism includes a partition mounting shaft horizontally fixed on the side wall of the furnace body, and partitions rotatably connected to both sides of the partition mounting shaft, a partition table is provided on the inner wall of the furnace body, the rotating end of the partition upwardly abuts against the partition table, the partition mounting shaft is arranged in the same direction below the first rotating shaft of the carbonization unloading mechanism, and an elastic reset component is provided between the partition mounting shaft and the partition to make the partition tend to move closer to the partition table; when the carbonization material tray rotates to the carbonization unloading position, the partition is pressed down to form the unloading channel between the partition and the partition table.

[0023] There are two transverse partitions, which are respectively located below the two carbonization unloading positions. The transverse partitions are rotatably connected to the partition mounting shaft. A partition table is fixed on the inner wall of the furnace body at the front end of the rotating end of the transverse partition. The rotating end of the transverse partition is located below the partition table, and the two are close to each other, so as to completely separate the working chamber. The elastic reset component makes the transverse partition have a tendency to rotate upward to fit closely with the partition table, but this tendency is elastic. When the carbonization material tray rotates downward to the carbonization unloading position, its side contacts the upper end surface of the transverse partition, and the transverse partition is pressed down to release the tight contact between the rotating end and the partition table, forming a unloading channel between them. The carbonized material falls from the unloading channel to the activation chamber along the inclined transverse partition, realizing the unloading of the carbonized material. When the carbonization material tray resets and rotates, the transverse partition is reset at the same time, reducing the atmosphere interaction time between the activation chamber and the carbonization chamber. As an optimization, the upper end of the partition table is provided with a downwardly inclined guide slope to reduce the accumulation and retention of carbonized material on the partition table.

[0024] As one of the optimizations, the elastic reset assembly includes a reset torsion spring arranged between the partition mounting shaft and the cross partition. Of course, other feasible elastic reset designs can also be used. The specific installation details of the reset torsion spring are common knowledge and will not be elaborated in detail.

[0025] In the above-mentioned activated carbon production equipment integrating carbonization and activation, a vertical partition fixed on the inner wall of the furnace body is vertically arranged in the activation chamber, and the vertical partition is located between the two activation material trays to separate the activation chamber into a first activation zone and a second activation zone.

[0026] The activation chamber is divided into a first activation zone and a second activation zone by a vertical partition. The two activation trays are respectively located in the first activation zone and the second activation zone, which reduces the interference effect of one activation tray on the reaction temperature or reaction atmosphere of the other activation tray when loading, thereby optimizing the activation effect.

[0027] In the above-mentioned activated carbon production equipment with integrated carbonization and activation, the side wall of the furnace body includes an inner layer and an outer layer, a first compartment is formed between the outer layer and the inner layer, a first partition plate is horizontally arranged in the middle of the first compartment to divide the first compartment into an activation temperature rising chamber of the activation temperature control mechanism and a carbonization temperature rising chamber of the carbonization temperature control mechanism, a first air inlet pipe and a first air outlet pipe connected to the carbonization temperature rising chamber, and a second air inlet pipe and a second air outlet pipe connected to the activation temperature rising chamber are penetrated through the outer layer, and the outer ends of the first air inlet pipe and the second air inlet pipe are respectively connected to the high-temperature flue gas generating components through pipelines; the activation temperature control mechanism and the carbonization temperature control mechanism also include at least two groups of temperature measuring components with detection ends located in the carbonization chamber or the activation chamber.

[0028] The side wall of the furnace body is provided with at least two layers, and a first compartment is formed between the inner layer and the outer layer. The first partition plate further divides the first compartment into two upper and lower heating chambers. The high-temperature flue gas generating component passes the high-temperature flue gas through the first air inlet pipe and the second air inlet pipe respectively through the heating chamber, and the temperature of the activation chamber and the carbonization chamber are controlled respectively through the activation heating chamber and the carbonization heating chamber, which is mainly used to increase the starting temperature. When the equipment is running stably, the heat brought by the activation atmosphere and the heat generated by the pyrolysis gas combustion reaction can realize the heating of the working chamber. The different temperatures of the activation heating chamber and the carbonization heating chamber are controlled by adjusting the high-temperature flue gas introduction rate or by introducing high-temperature flue gas of different temperatures. The temperature measuring component is used to specifically test the temperature in the chamber, and to provide feedback to ensure the accuracy and stability of the temperature.

[0029] In the above-mentioned activated carbon production equipment with integrated carbonization and activation, an intermediate layer is further provided between the outer layer and the inner layer, a second compartment is formed between the intermediate layer and the inner layer, and the first compartment is formed between the intermediate layer and the outer layer, a second partition plate flush with the first partition plate is horizontally arranged in the middle of the second compartment, and the second compartment is divided into an activation cooling chamber of the activation temperature control mechanism and a carbonization cooling chamber of the carbonization temperature control mechanism, a first water inlet pipe and a first steam output pipe connected to the carbonization cooling chamber, as well as a second water inlet pipe and a second steam output pipe connected to the activation cooling chamber are penetrated through the intermediate layer and the outer layer, and the first water inlet pipe and the second water inlet pipe are respectively connected to the water supply assembly through pipelines.

[0030] There is also a middle layer between the outer layer and the inner layer, the inside of the middle layer is the second compartment, and the outside of the middle layer is the first compartment. The second compartment is also divided into two cooling chambers. Water is introduced into the carbonization cooling chamber and the activation cooling chamber through the first water inlet pipe and the second water inlet pipe to achieve cooling control. The introduced water will be vaporized due to the high temperature of the side wall of the furnace body, and the generated water vapor is output through the first steam output pipe and the second steam output pipe, which can be used for introducing gas mixing to provide part of the water vapor required for the activation atmosphere. The two heating chambers and the two cooling chambers are coordinated to ensure that the temperature of the carbonization and activation reactions is appropriate and stable. When the temperature is higher than the preset value, cooling is achieved by introducing water, thereby improving energy utilization.

[0031] As an optimization, a heat-conducting connector is provided between the middle layer and the inner layer. The heat-conducting connector is cylindrical or sheet-shaped, and its two ends are respectively fixedly connected to the opposite side walls of the middle layer and the inner layer for heat conduction.

[0032] In the above-mentioned activated carbon production equipment integrating carbonization and activation, the activation atmosphere supply assembly includes a gas mixing chamber, and the outer ends of the first steam output pipe and the second steam output pipe are connected to the gas input end of the gas mixing chamber;

[0033] The upper part of the furnace body is provided with a pyrolysis gas outlet communicating with the carbonization chamber, and the outer end of the pyrolysis gas outlet is connected to the gas input end of the gas mixing chamber;

[0034] The outer ends of the first gas outlet pipe and the second gas outlet pipe are connected to a boiler assembly for generating steam, the steam output end of the boiler assembly is connected to the gas input end, and the boiler assembly is also connected to a water supply assembly;

[0035] The mixing output end of the gas mixing chamber is connected with a first output pipe and a second output pipe respectively. The first output pipe and the second output pipe respectively penetrate the side wall of the furnace body and communicate with the first activation zone and the second activation zone of the activation chamber.

[0036] The gas input end of the gas mixing chamber is respectively connected to the first steam output pipe, the second steam output pipe, the pyrolysis gas output port and the boiler assembly, wherein the first steam output pipe and the second steam output pipe are used to input the water vapor generated by cooling into the gas mixing chamber to provide part of the water vapor required for activation, and the boiler assembly is used to provide the remaining water vapor. The pyrolysis gas output port inputs the pyrolysis gas generated by carbonization into the gas mixing chamber, and the pyrolysis gas undergoes a combustion reaction in the activation chamber to provide heat. At the same time, the activated atmosphere introduced has its own heat, so that the system can be self-operated and cost-saving. The gas mixing chamber is used to mix the various gases in corresponding proportions and then input them into the activation chamber through the output pipe, and the first output pipe and the second output pipe are respectively connected to the first activation zone and the second activation zone, and the activation atmosphere of the two zones can be controlled respectively, reducing interference and improving the activation effect. The mixing ratio and mixing structure of the gas mixing chamber are common knowledge and prior art, and will not be elaborated in detail.

[0037] In the above-mentioned activated carbon production equipment with integrated carbonization and activation, a waste gas output pipe connected to the activation chamber is provided on the side wall of the furnace body, and the waste gas output pipe is connected to a high-temperature flue gas generating assembly for fully burning the waste gas. The high-temperature flue gas generating assembly is connected to a boiler assembly, and a water washing and cooling assembly is also connected to the boiler assembly for washing the flue gas after heat exchange and discharging it after cooling.

[0039] As an optimization, a switch valve assembly is provided on each relevant pipeline, and the on-off control of the pipeline is achieved through the switch valve assembly.

[0040] Another object of the present invention is to propose a method for solving the above-mentioned problems in the prior art.

[0041] Compared with the prior art, the present invention mainly has the following advantages:

[0042] 1. The activated carbon production equipment of the present invention is used to realize the integrated production of raw material-carbonized material-activated carbon. The raw material is fed from the feeding port to the carbonized material tray in the carbonization chamber. The carbonization temperature control mechanism maintains the temperature of the carbonization chamber at the temperature required for carbonization. The raw material undergoes carbonization reaction on the carbonized material tray. After the carbonization is completed, the carbonization unloading mechanism rotates the carbonized material tray to one side, and the carbonized material tray enters the carbonization unloading position, and during the entry process, the diaphragm mechanism opens the unloading channel, and the carbonized material enters the activation material tray in the activation chamber from the unloading channel. The activation temperature control mechanism controls the activation chamber at the required temperature for activation, and the activation atmosphere supply component keeps the activation chamber at a suitable activation atmosphere. The carbonized material is activated under suitable temperature and atmosphere conditions to form activated carbon. After the activation is completed, the activation unloading mechanism drives the activation material tray to rotate, so that the activation material tray enters the activation unloading position to pour out the activated carbon, and the activated carbon is output from the discharge port below, completing the integrated production of raw materials to activated carbon. In specific production, the time required for the carbonization process is shorter than that required for the activation process. In order to improve production efficiency, the carbonization tray is tilted to the left or right to form two activation material discharge positions, and a carbonization tray is docked under each activation material discharge position to reduce the idle waiting time of the activation tray and the carbonization tray. In addition, the activation temperature control mechanism and the carbonization temperature control mechanism control the temperature environment of the activation chamber and the carbonization chamber respectively, optimize the reaction effect of carbonization and activation, and improve product quality. Moreover, the diaphragm mechanism separates the carbonization chamber and the activation chamber to avoid or reduce the activation atmosphere of the activation chamber from entering the carbonization chamber, reduce the temperature interference between the two and the reaction atmosphere interference, and further ensure product quality.

[0043] 2. The carbonization tray is fixed on the first rotating shaft, and the carbonization unloading motor drives the rotation of the carbonization tray, thereby realizing the switching of the carbonization tray between the carbonization reaction position and the carbonization unloading position. The structure is simple and the control is stable. The cross-sections of the carbonization tray and the activation tray are arc-shaped or trapezoidal, which prevents the material from falling out from both sides. At the same time, it also makes it easy for the raw materials to be poured out when the carbonization tray rotates and tilts. The dumping effect can be achieved by rotating a certain acute angle, reducing the possibility of carbonized material retention.

[0044] 3. The material shifting structure is used to shift the material evenly to avoid the material piling up like a mountain on the carbonizing tray, so that the material is heated evenly and the carbonization effect is optimized. The material shifting plate is fixed on the material shifting shaft. The material shifting drive motor drives the material shifting shaft to rotate and then realizes the rotation of the material shifting plate to shift the accumulated material evenly. The material passing gap is the expected thickness to make the material evenly spread on the carbonizing tray. When the carbonizing tray is about to rotate to discharge the material, the material shifting plate rotates to the other side to avoid affecting the carbonizing tray from entering the carbonization discharge position. The baffle is set above the material shifting shaft. On the one hand, it is used to prevent the raw materials from sticking to the material shifting shaft. On the other hand, its upper end forms a sharp corner, which can guide the material to both sides when it is put in, reducing the stacking height on the carbonizing tray to a certain extent.

[0045] 4. Two baffles are provided, which are respectively located below the two carbonization unloading positions. The rotating end of the baffle is located below the partition table, and the two are in contact with each other, so as to completely separate the working chamber. The elastic reset component makes the baffle have a tendency to rotate upward to fit closely to the partition table, but this tendency is elastic. When the carbonization material tray rotates downward to the carbonization unloading position, its side contacts the upper end surface of the baffle, and the baffle is pressed down to release the rotating end from the close contact with the partition table, forming a unloading channel therebetween. The carbonized material falls from the unloading channel into the activation chamber along the inclined baffle, so as to realize the unloading of the carbonized material. When the carbonization material tray resets and rotates, the baffle is reset at the same time, so as to reduce the atmosphere interaction time between the activation chamber and the carbonization chamber.

[0046] 5. The activation chamber is divided into the first activation zone and the second activation zone by a vertical partition. The two activation trays are respectively located in the first activation zone and the second activation zone, which reduces the interference of one activation tray on the reaction temperature or reaction atmosphere of the other activation tray when loading, and optimizes the activation effect.

[0047] 6. The side wall of the furnace body is provided with at least two layers, and a first compartment is formed between the inner layer and the outer layer. The first partition plate divides the first compartment into two upper and lower temperature-raising chambers. The high-temperature flue gas generating component passes the high-temperature flue gas through the first air inlet pipe and the second air inlet pipe respectively through the temperature-raising chamber, and the temperature of the activation chamber and the carbonization chamber are controlled respectively through the activation temperature-raising chamber and the carbonization temperature-raising chamber, which is mainly used to increase the starting temperature.

[0048] 7. There is an intermediate layer between the outer layer and the inner layer, and the second compartment is inside the intermediate layer. Water is introduced into the carbonization cooling chamber and the activation cooling chamber through the first water inlet pipe and the second water inlet pipe to achieve temperature control. The introduced water will be vaporized due to the high temperature of the side wall of the furnace body, and the generated water vapor is output through the first steam output pipe and the second steam output pipe, which can be used to introduce gas mixing and to provide part of the water vapor required for the activation atmosphere. The two heating chambers and the two cooling chambers are coordinated and controlled to ensure that the temperature of the carbonization and activation reactions is appropriate and stable.

[0049] 8. The gas input end of the gas mixing chamber is respectively connected to the first steam output pipe, the second steam output pipe, the pyrolysis gas output port and the boiler assembly, wherein the first steam output pipe, the second steam output pipe and the boiler assembly are used to provide part of the water vapor required for activation, and the pyrolysis gas output port provides heat for the combustion reaction of the pyrolysis gas generated by carbonization in the activation chamber, and the activated atmosphere introduced at the same time carries its own heat, so that the system can be self-operated and cost-saving.

[0050] 9. The residual gas output pipe is used to output the gas after the combustion reaction and the activation reaction, in which there are inevitably residual combustible components. The gas is passed into the high-temperature flue gas generating component for further combustion and can be used as a fuel for the production of high-temperature flue gas, saving costs, and can also purify the exhaust gas and protect the environment. The output end of the high-temperature flue gas generating component is also connected to the boiler component to provide heat for the operation of the boiler component. The water washing and cooling component is used to wash the flue gas after the heat exchange work of the boiler component with water and cool it before discharging it, reducing the impact on the atmospheric environment.

[0062] Specifically, the activated carbon production equipment of the present invention is used to realize the integrated production of raw materials, carbonized materials and activated carbon. The raw materials are fed from the feeding port 11 to the carbonized material tray 21 in the carbonization chamber 2. The carbonization temperature control mechanism 5 maintains the temperature of the carbonization chamber 2 at the temperature required for carbonization. The raw materials undergo carbonization reaction on the carbonized material tray 21. After the carbonization is completed, the carbonization unloading mechanism 22 rotates the carbonized material tray 21 to one side, and the carbonized material tray 21 enters the carbonization unloading position. During the entry process, the diaphragm mechanism 4 opens the unloading channel, and the carbonized material enters from the unloading channel. On the activation tray 31 in the activation chamber 3, the activation temperature control mechanism 6 controls the activation chamber 3 at the temperature required for activation, and the activation atmosphere supply component 7 keeps the activation chamber 3 at a suitable activation atmosphere. The carbonized material is activated under suitable temperature and atmosphere conditions to form activated carbon. After the activation is completed, the activation unloading mechanism 38 drives the activation tray 31 to rotate, so that the activation tray 31 enters the activation unloading position to pour out the activated carbon, and the activated carbon is output from the discharge port 12 below, completing the integrated production of raw materials to activated carbon. Of course, the raw materials here are pretreated accordingly. During specific production, the time required for the carbonization process is shorter than the time required for the activation process. In order to improve production efficiency, the carbonization tray 21 is tilted to the left or right to form two activation unloading positions, and a carbonization tray 21 is docked under each activation unloading position to reduce the idle waiting time of the activation tray 31 and the carbonization tray 21. In addition, the activation temperature control mechanism 6 and the carbonization temperature control mechanism 5 control the temperature environment of the activation chamber 3 and the carbonization chamber 2 respectively, optimize the reaction effect of carbonization and activation, and improve the product quality. Moreover, the diaphragm mechanism 4 separates the carbonization chamber 2 and the activation chamber 3, avoids or reduces the activation atmosphere of the activation chamber 3 from entering the carbonization chamber 2, reduces the temperature interference and reaction atmosphere interference between the two, and further ensures the product quality. Among them, the opening and closing door components are respectively provided on the discharge port 12 and the feeding port 11. The opening and closing door components keep the discharge port 12 and the feeding port 11 closed when feeding or discharging is not required, reducing the influence of the external environment on the heat or reaction atmosphere of the working chamber.

[0063] like Figure 1 , 2As shown, the carbonization unloading mechanism 22 includes a first rotating shaft 23 and a carbonization unloading motor. The first rotating shaft 23 is rotatably connected to the side wall of the furnace body 1, and both ends pass through the outer wall of the furnace body 1, and one end is drivingly connected to the output end of the carbonization unloading motor; the cross section of the carbonization material tray 21 is an arc-shaped with a large top and a small bottom, and a carbonization material receiving cavity 29 is formed on the carbonization material tray 21. The first rotating shaft 23 is fixed below the carbonization material tray 21. The carbonization material tray 21 is linear, with baffles at both ends to form a groove structure, and the length direction of the first rotating shaft 23 is consistent with the length direction of the carbonization material tray 21. A material shifting structure 24 for shifting materials evenly is provided above the carbonizing material receiving chamber 29. The material shifting structure 24 includes a material shifting plate 26 rotatably connected to the inner wall of the furnace body 1 through a material shifting shaft 25. The material shifting plate 26, the material shifting shaft 25 and the first shaft 23 are all arranged in the same direction. Both ends of the material shifting shaft 25 pass through the side wall of the furnace body 1, and one end is transmission-connected to the output end of the material shifting driving motor. There is a material passing gap 27 between the lower end of the material shifting plate 26 and the inner surface of the carbonizing material receiving chamber 29; a baffle 28 with an inverted V-shaped cross-section is provided between the material shifting structure 24 and the feeding port 11, and both ends of the baffle 28 are fixed to the inner wall of the furnace body 1, and the baffle 28 and the material shifting shaft 25 are consistent in length direction and are located above the material shifting shaft 25.

[0064] Specifically, the carbonization material tray 21 is fixed on the first rotating shaft 23, and the carbonization unloading motor drives the rotation of the carbonization material tray 21, thereby realizing the switching of the carbonization material tray 21 between the carbonization reaction position and the carbonization unloading position. The structure is simple and the control is stable. The cross-section of the carbonization material tray 21 is arc-shaped or trapezoidal, which prevents the material from falling out from both sides. At the same time, it also makes it easy for the raw materials to be poured out when the carbonization material tray 21 is rotated and tilted. The dumping effect can be achieved by rotating a certain acute angle, reducing the possibility of carbonized material retention. The material shifting structure 24 is used to shift the material evenly to avoid the material piling up like a mountain on the carbonizing material tray 21, so that the material is heated evenly and the carbonization effect is optimized. The material shifting plate 26 is fixed on the material shifting shaft 25. The material shifting drive motor drives the material shifting shaft 25 to rotate and then realizes the rotation of the material shifting plate 26 to shift the accumulated material evenly. The material passing gap 27 is the expected thickness for evenly spreading the material on the carbonizing material tray 21. When the carbonizing material tray 21 is to rotate to discharge the material, the material shifting plate 26 rotates to the other side to avoid affecting the carbonizing material tray 21 entering the carbonization discharge position. As an optimization, the material shifting structure 24 is located in the middle and upper part of the carbonization material receiving chamber 29, which ensures the uniformity of the material shifting and avoids the different influences on the carbonizing material tray 21 entering any carbonization discharge position. The baffle 28 is arranged above the material-dispensing rotating shaft 25. On the one hand, it is used to prevent the raw materials from sticking to the material-dispensing rotating shaft 25. On the other hand, its upper end forms a sharp angle, which can guide the materials to both sides when they are put in, thereby reducing the stacking height on the carbonization material tray 21 to a certain extent.

[0065] like Figure 1As shown, similar to the carbonizing material tray 21, the cross-section of the activation material tray 31 is an arc-shaped with a larger upper part and a smaller lower part. An activation material receiving cavity 32 is formed in the activation material tray 31. A horizontally arranged second rotating shaft 33 is fixedly provided below the carbonizing material tray 21. Both ends of the second rotating shaft 33 are rotatably connected to the side walls of the furnace body 1, and both ends pass through the outer wall of the furnace body 1, and one end is transmission-connected to the output end of the activation unloading motor.

[0066] Specifically, the activation material tray 31 is also arc-shaped like the carbonization material tray 21, and its width is about half of the carbonization material tray 21. The carbonized material falls into the activation material receiving chamber 32 for activation reaction. The activation unloading motor drives the activation material tray 31 to rotate through the second rotating shaft 33, so that the activation material tray 31 switches between the activation reaction position and the activation unloading position. The structure is simple and the control is stable.

[0067] like Figure 1 , 2 As shown, the partition mechanism 4 includes a partition mounting shaft 41 horizontally fixed on the side wall of the furnace body 1, and partitions 42 rotatably connected to both sides of the partition mounting shaft 41, a partition table 43 is provided on the inner wall of the furnace body 1, and the rotating end of the partition 42 upwardly abuts against the partition table 43, and the partition mounting shaft 41 is arranged in the same direction below the first rotating shaft 23 of the carbonization unloading mechanism, and an elastic reset component 44 is provided between the partition mounting shaft 41 and the partition 42, which makes the partition 42 tend to move closer to the partition table 43; when the carbonization material tray 21 rotates to the carbonization unloading position, the partition 42 is pressed down to form a unloading channel between the partition 42 and the partition table 43.

[0068] Specifically, two baffles 42 are provided, which are respectively located below the two carbonization unloading positions. The baffles 42 are rotatably connected to the baffle mounting shaft 41. A partition table 43 is fixed on the inner wall of the furnace body 1 at the front end of the rotating end of the baffle 42. The rotating end of the baffle 42 is located below the partition table 43, and the two are in contact with each other, so as to completely separate the working chamber. The elastic reset component 44 makes the baffle 42 have a tendency to rotate upward to fit closely with the partition table 43, but this tendency is elastic. When the carbonization material tray 21 rotates downward to the carbonization unloading position, its side contacts the upper end surface of the baffle 42, and the baffle 42 is pressed down to release the rotating end from the close contact with the partition table 43, forming a unloading channel therebetween. The carbonized material falls from the unloading channel into the activation chamber 3 along the inclined baffle 42, so as to realize the unloading of the carbonized material. When the carbonization material tray 21 resets and rotates, the baffle 42 is reset at the same time, so as to reduce the atmosphere interaction time between the activation chamber 3 and the carbonization chamber 2. As an optimization, a downwardly inclined guide slope is provided at the upper end of the partition table 43 to reduce the accumulation and retention of carbonized materials on the partition table 43. The elastic reset component 44 includes a reset torsion spring disposed between the partition plate mounting shaft 41 and the transverse partition plate 42.

[0069] like Figure 1 , 2As shown, the side wall of the furnace body 1 includes an inner layer 13, a middle layer 14 and an outer layer 15, a first compartment is formed between the outer layer 15 and the middle layer 14, a first partition plate 16 is transversely arranged in the middle of the first compartment to divide the first compartment into an activation temperature rising chamber 61 of the activation temperature control mechanism 6 and a carbonization temperature rising chamber 51 of the carbonization temperature control mechanism 5, a first air inlet pipe 52 and a first air outlet pipe 53 connected to the carbonization temperature rising chamber 51, and a second air inlet pipe 62 and a second air outlet pipe 63 connected to the activation temperature rising chamber 61 are penetrated through the outer layer 15, and the outer ends of the first air inlet pipe 52 and the second air inlet pipe 62 are respectively connected to the high-temperature flue gas generating component 81 through pipelines; the activation temperature control mechanism 6 and the carbonization temperature control mechanism 5 also include at least two groups of temperature measuring components 18 with detection ends located in the carbonization chamber 2 or the activation chamber 3. A second compartment is formed between the middle layer 14 and the inner layer 13, and a second partition plate 17 flush with the first partition plate 16 is horizontally arranged in the middle of the second compartment to divide the second compartment into an activation cooling chamber 64 of the activation temperature control mechanism 6 and a carbonization cooling chamber 54 of the carbonization temperature control mechanism 5. A first water inlet pipe 55 and a first steam output pipe 56 connected to the carbonization cooling chamber 54, as well as a second water inlet pipe 65 and a second steam output pipe 66 connected to the activation cooling chamber 64 are penetrated through the middle layer 14 and the outer layer 15. The first water inlet pipe 55 and the second water inlet pipe 65 are respectively connected to the water supply assembly 82 through pipelines.

[0070] Specifically, the side wall of the furnace body 1 is provided with multiple layers, and a first compartment is formed between the middle layer 14 and the outer layer 15. The first partition plate 16 divides the first compartment into two upper and lower temperature rising chambers. The high-temperature flue gas generating component 81 passes the high-temperature flue gas through the first air inlet pipe 52 and the second air inlet pipe 62 respectively through the temperature rising chamber, and the temperature control of the activation chamber 3 and the carbonization chamber 2 is realized respectively through the activation temperature rising chamber 61 and the carbonization temperature rising chamber 51, which is mainly used to increase the starting temperature. When the equipment is running stably, the heat brought by the activation atmosphere and the heat generated by the pyrolysis gas combustion reaction can realize the temperature rising of the working chamber. The different temperatures of the activation temperature rising chamber 61 and the carbonization temperature rising chamber 51 are controlled differently by adjusting the high-temperature flue gas introduction rate or by introducing high-temperature flue gas of different temperatures. The temperature measuring component 18 is used to specifically test the temperature in the chamber, and to provide feedback to ensure the accuracy and stability of the temperature. The middle layer 14 is within the second compartment, and the second compartment is also divided into two cooling chambers. Water is introduced into the carbonization cooling chamber 54 and the activation cooling chamber 64 through the first water inlet pipe 55 and the second water inlet pipe 65 to achieve cooling control. The introduced water will be vaporized due to the high temperature of the side wall of the furnace body 1, and the generated water vapor is output through the first steam output pipe 56 and the second steam output pipe 66, which can be used to introduce gas mixing to provide part of the water vapor required for the activation atmosphere. The two heating chambers and the two cooling chambers are coordinated and controlled to ensure that the temperature of the carbonization and activation reactions is appropriate and stable. When the temperature is higher than the preset value, cooling is achieved by introducing water, thereby improving energy utilization.

[0071] As an optimization of this embodiment, a heat-conducting connector is provided between the middle layer 14 and the inner layer 13. The heat-conducting connector is cylindrical or sheet-shaped, and its two ends are respectively fixedly connected to the opposite side walls of the middle layer 14 and the inner layer 13 for heat conduction.

[0072] In this embodiment, a vertical partition 34 fixed to the inner wall of the furnace body 1 is vertically arranged in the activation chamber 3 . The vertical partition 34 is located between the two activation trays 31 , and separates the activation chamber 3 into a first activation zone 35 and a second activation zone 36 . The activation atmosphere supply assembly 7 includes a gas mixing chamber 71, and the outer ends of the first steam output pipe 56 and the second steam output pipe 66 are connected to the gas input end of the gas mixing chamber 71; a pyrolysis gas output port 19 connected to the carbonization chamber 2 is provided on the upper part of the furnace body 1, and the outer end of the pyrolysis gas output port 19 is connected to the gas input end of the gas mixing chamber 71; the outer ends of the first gas outlet pipe 53 and the second gas outlet pipe 63 are connected to a boiler assembly 74 for generating steam, the steam output end of the boiler assembly 74 is connected to the gas input end, and the boiler assembly 74 is also connected to the water supply assembly 82; the first output pipe 72 and the second output pipe 73 are respectively connected to the mixing output end of the gas mixing chamber 71, and the first output pipe 72 and the second output pipe 73 respectively pass through the side wall of the furnace body 1 and are connected to the first activation zone 35 and the second activation zone 36 of the activation chamber 3.

[0073] Specifically, the gas input end of the gas mixing chamber 71 is respectively connected to the first steam output pipe 56, the second steam output pipe 66, the pyrolysis gas output port 19 and the boiler assembly 74, wherein the first steam output pipe 56 and the second steam output pipe 66 are used to input the water vapor generated by cooling into the gas mixing chamber 71 to provide part of the water vapor required for activation, and the boiler assembly 74 is used to provide the remaining water vapor. The pyrolysis gas output port 19 inputs the pyrolysis gas generated by carbonization into the gas mixing chamber 71, and the pyrolysis gas undergoes a combustion reaction in the activation chamber 3 to provide heat. At the same time, the activated atmosphere introduced has its own heat, so that the system can be self-operated and cost-saving. The gas mixing chamber 71 is used to mix the various gases in corresponding proportions and then input them into the activation chamber 3 through the output pipe, and the first output pipe 72 and the second output pipe 73 are respectively connected to the first activation zone 35 and the second activation zone 36, which can control the activation atmosphere of the two zones respectively, reduce interference, and improve the activation effect. The activation chamber 3 is divided into a first activation zone 35 and a second activation zone 36 by a vertical partition 34. The two activation trays 31 are respectively located in the first activation zone 35 and the second activation zone 36, thereby reducing the interference effect of one activation tray 31 on the reaction temperature or reaction atmosphere of the other activation tray 31 when loading materials, thereby optimizing the activation effect.

[0074] As an optimization of this embodiment, a waste gas output pipe 37 connected to the activation chamber 3 is provided on the side wall of the furnace body 1. The waste gas output pipe 37 is connected to the high-temperature flue gas generating assembly 81 for fully burning the waste gas. The high-temperature flue gas generating assembly 81 is connected to the boiler assembly 74. The boiler assembly 74 is also connected to a water washing and cooling assembly 83 for washing the flue gas after heat exchange and discharging it after cooling. The high-temperature flue gas generating assembly 81 is also connected to a fuel supply assembly 84.

[0075] Specifically, the residual gas output pipe 37 is used to output the gas after the combustion reaction and the activation reaction, in which there are inevitably residual combustible components. The gas is passed into the high-temperature flue gas generating component 81 for further combustion and can be used as a fuel for the production of high-temperature flue gas, saving costs, and purifying exhaust gases to protect the environment. The output end of the high-temperature flue gas generating component 81 is also connected to the boiler component 74 to provide heat for the operation of the boiler component 74. The water washing and cooling component 83 is used to wash and cool the flue gas after the heat exchange work of the boiler component 74 before discharging it, thereby reducing the impact on the atmospheric environment.

[0076] In this embodiment, switch valve assemblies are respectively provided between the water supply assembly 82, the high-temperature flue gas generating assembly 81, the first air outlet pipe 53, the second air outlet pipe 63, the gas mixing chamber 71, the water washing cooling assembly 83 and the boiler assembly 74; between the fuel supply assembly 84, the residual gas output pipe 37, the first air intake pipe 52, the second air intake pipe 62 and the high-temperature flue gas generating assembly 81; and between the boiler assembly 74, the pyrolysis gas output port 19, the first steam output pipe 56, the second steam output pipe 66 and the gas mixing chamber 71.

[0077] Specific working principle: At startup, biomass pellet fuel is input into the high-temperature flue gas generating component 81 through the fuel supply component 85 to burn, generating high-temperature flue gas, which is respectively passed into the carbonization heating chamber 51 and the activation heating chamber 61 through the first air inlet pipe 52 and the second air inlet pipe 62, and the temperature of the carbonization chamber 2 and the activation chamber 3 is increased to reach the preset temperature.

[0078] After the temperature is adjusted to the desired level, the switch door assembly of the feeding port 11 is opened, the raw materials are put in and the switch door assembly is closed. The raw materials are accumulated on the carbonization material tray 21. Then the material shifting drive motor is activated, and the material shifting plate 26 reciprocates to shift the raw materials roughly evenly. The raw materials are slightly burned in the carbonization chamber 2 at the beginning. After the oxygen is exhausted, the carbonization reaction begins. After 10 minutes, the carbonization is completed to form carbonized material.

[0079] The pyrolysis gas generated during the carbonization reaction enters the gas mixing station through the pyrolysis gas output port 19, and at the same time, the high-temperature flue gas generating component 81 passes part of the high-temperature flue gas into the boiler component 74. The boiler component 74 generates water vapor and inputs the water vapor into the gas mixing chamber 71. The gas mixing chamber 71 mixes the pyrolysis gas, water vapor and air in proportion and passes them through the first activation zone 35 and the second activation zone 36 respectively for combustion and heat supply. After that, the first air inlet pipe 52 and the second air inlet pipe 62 no longer need to continue to pass a large amount of high-temperature flue gas.

[0080] When the carbonized material is unloaded, the carbonized unloading motor is activated, and the carbonized material tray 21 rotates to the left carbonized unloading position. When it rotates to the second half of the stroke, the lower side of the carbonized material tray 21 presses down the diaphragm 42 to form a unloading channel between the rotating end and the partition 43. As the inclination angle increases, the carbonized material pours down under the action of gravity, passes through the diaphragm 42 and the unloading channel, and accumulates on the activation material tray 31 of the first activation area 35. After the carbonized material is unloaded, the carbonized material tray 21 rotates in the opposite direction to reset, and the feeding and activation work continues. The carbonized material undergoes an activation reaction in the activation atmosphere on the activation material tray 31.

[0081] After 10 minutes, another batch of carbonized materials on the carbonized material tray 21 is completed, the carbonized material unloading motor is activated, and the carbonized material tray 21 rotates to the carbonized material unloading position on the right side. Similarly, the carbonized materials are poured onto the activation material tray 31 in the second activation zone 36, and then the cycle is reset.

[0082] After another 10 minutes, the carbonized material on the first activation tray 31 is activated and turned into activated carbon, the activation discharge motor starts, the activation tray 31 rotates to the activation discharge position, and at the same time, the switch door assembly of the discharge port 12 opens, and the activated carbon is discharged from the discharge port 12.

[0083] After the activated carbon is discharged, the switch door assembly of the discharge port 12 and the activation tray 31 rotate and reset, and another batch of carbonized materials on the carbonization tray 21 is just generated. The material discharge and activation operation can be started in the same way, and the cycle continues.

[0084] During the temperature control process, for example, when the temperature of the carbonization chamber 2 is higher than the preset value, the water supply component 82 introduces an appropriate amount of water into the carbonization cooling chamber 54 through the first water inlet pipe 55, where the water vaporizes and absorbs heat to achieve cooling, and the water vapor generated in the process is introduced into the gas mixing chamber 71. When the temperature reaches the preset value, the high-temperature flue gas of the high-temperature flue gas generating component 81 is introduced into the carbonization heating chamber 51 through the first air inlet pipe 52 in an appropriate amount to adjust the temperature to the preset level.

[0085] The temperature control of the activation chamber 3 is similar.

[0086] The gas after heat exchange in the boiler component 74 finally passes through the water washing and cooling component 83 to absorb dust and reduce the temperature before being discharged.

[0087] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
