Description

Technical Field

[0001] The invention relates to the technical field of carbonization furnaces, and in particular to a vertical continuous high-temperature carbonization furnace device. Background Art

[0002] Carbonization furnace is a device that converts organic matter into carbon by heating graphite at high temperature. Its working principle mainly includes four processes: preheating, heating, carbonization and cooling.

[0003] Before the high-temperature carbonization furnace starts working, the furnace needs to be preheated first. Preheating is to improve work efficiency and protect equipment. By controlling the heating elements, the temperature inside the furnace is gradually raised to the set working temperature. After the preheating is completed, organic matter (such as wood, fruit shells, etc.) is placed in the furnace. The organic matter is heated by high-temperature graphite or other heating elements. As the heating proceeds, the organic matter gradually turns into carbon. The organic matter will decompose under high temperature conditions to produce gas and liquid, while releasing a large amount of heat. As the heating proceeds, the organic matter gradually turns into carbon. Under high temperature conditions, the carbon atoms in the organic matter gradually arrange into a chain structure to form a dense carbon layer. After carbonization is completed, the temperature in the furnace needs to be gradually reduced so that the carbon layer will not be too fragile. By controlling the heating elements or other cooling equipment, the temperature inside the furnace is gradually reduced.

[0004] However, the existing carbonization furnace still has shortcomings:

[0005] 1. Material particles are usually placed directly in a graphite crucible for heating. Since the graphite crucible has a certain volume, if the material particles are piled up in the graphite crucible for heating, the material particles will be heated unevenly, affecting the heating and carbonization effect of the material particles;

[0006] 2. Waste gas will be generated during the heating and carbonization process of the material particles. The waste gas usually rises directly and is discharged from the exhaust port at the upper end of the furnace body. The waste gas will carry the material out during the discharge process. Summary of the invention

[0007] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a vertical continuous high-temperature carbonization furnace equipment which effectively solves the problem in the prior art that material particles are unevenly heated, affecting the heating and carbonization effect of material particles, and that waste gas carries material out during the discharge process.

DETAILED DESCRIPTION

[0031] like Figure 1-8 As shown, a vertical continuous high-temperature carbonization furnace device includes a frame steel platform 1 and a temperature control system. The upper end of the frame steel platform 1 is provided with a carbonization furnace body. The carbonization furnace body includes a feeding partition 4, a heating partition 3 and a cooling partition 5, each of which can set the internal temperature separately. A plurality of graphite crucibles 8 that are stacked and can be driven to rotate synchronously are arranged in the carbonization furnace body. A cylindrical turntable 25 is arranged in the middle of the graphite crucible 8 for transmission. A multi-faceted graphite crucible that penetrates the cylindrical turntable 25 is fixedly arranged on the frame steel platform 1. The graphite crucible 8 has a plurality of graphite axes 16, and graphite claw bodies 17 fixedly connected to the multi-faceted graphite axes 16 are respectively arranged in the graphite crucible 8. The bottom of the graphite crucible 8 is provided with leakage holes 24 corresponding to the graphite claw bodies 17, and the leakage holes 24 on the stacked graphite crucibles 8 are staggered by 120° between layers. A discharge barrel 11 connected to the carbonization furnace body is arranged at the lower end of the frame steel platform 1, and a discharge valve port 28 is arranged on the discharge barrel 11. The temperature control system is used to control the temperature and heat the material particles in the feeding partition 4 and the heating partition 3.

[0032] When the present invention is used, the feeding partition 4, the heating partition 3 and the cooling partition 5 in the furnace of the carbonization furnace body are preheated and heated respectively. Preheating can improve the working efficiency. The material particles are added into the graphite crucible 8 of the feeding partition 4 of the carbonization furnace body. At the same time, the superimposed graphite crucibles 8 are controlled to be driven to rotate synchronously. Since the multi-faceted graphite shaft 16 fixes the graphite climbing claw body 17 in the graphite crucible 8, when the graphite crucible 8 is rotated, the material flow inside the graphite crucible 8 performs a lateral rotation motion, and the continuously added material flow is guided, so that the material flow performs a circular motion in the horizontal plane of the superimposed graphite crucible 8. Under the action of the graphite climbing claw body 17, the material flow moves in a specified circle. The leakage holes 24 in the graphite crucible 8 at the corner position flow into the lower layer, and the movement of the material flow realizes the collision, friction and extrusion between the material particles, and the material is evenly heated. The material is heated in the graphite crucible 8 superimposed by the pre-carbonization of the feeding section 4 and simultaneously rotates sideways layer by layer. The material is heated in the graphite crucible 8 superimposed by the high-temperature carbonization of the heating section 3 and simultaneously rotates sideways layer by layer. The material moves to the graphite crucible 8 superimposed by the cooling section 5 and simultaneously rotates sideways layer by layer, and finally rolls into the discharge barrel 11, and the discharge is controlled by the discharge valve port 28. The leakage holes 24 in different graphite crucibles 8 are staggered by 120° between layers, which can form a spiral climb for the exhaust gas to the exhaust port 7 on the top of the furnace without easily carrying the material to escape upward.

[0033] The feeding compartment 4, the heating compartment 3 and the cooling compartment 5 are all provided with an electric heating field 27, and the electric heating field 27 adopts a silicon-molybdenum rod electric heating field 27. The upper end of the carbonization furnace body is provided with an electric connector 29 electrically connected to the electric heating field 27.

[0034] like Figure 2 As shown, the electric heating field 27 is energized through the electric connector 29, and the silicon-molybdenum rod electric heating field 27 is used to heat the feeding compartment 4, the heating compartment 3 and the cooling compartment 5, and the internal temperatures of the feeding compartment 4, the heating compartment 3 and the cooling compartment 5 can be controlled separately to achieve continuous production. The material is gradually heated up, continuously heated and continuously cooled through different temperature sections, and a better controllable temperature control curve is achieved for the powder fiber.

[0035] The frame steel platform 1 is provided with a rotating table 18 for transmission, and a second gear 9 is provided on the rotating table 18. The second gear 9 is meshed with a first gear 10 rotatably connected to the frame steel platform 1, and a rotating column 22 is provided on the first gear 10. A motor 12 and a reducer 14 are respectively provided at the lower end of the frame steel platform 1, and the output end of the motor 12 is fixedly connected to a first pulley 13, and the input end of the reducer 14 is fixedly connected to a second pulley 15, the first pulley 13 is connected to the second pulley 15 by belts, and the output end of the reducer 14 is connected to the rotating column 22.

[0036] like Figure 2-5As shown, the motor 12 drives the first pulley 13 to rotate, the first pulley 13 drives the second pulley 15 to rotate, the second pulley 15 drives the reducer 14 to work, the output end of the reducer 14 drives the rotating column 22 to rotate, the rotating column 22 drives the first gear 10 to rotate, the first gear 10 drives the second gear 9 to rotate, and the second gear 9 drives the rotating table 18 to rotate. Since the graphite crucible 8 is limitedly set on the rotating table 18, the rotating table 18 is used to synchronously drive the graphite crucible 8 to rotate.

[0037] A limiting groove 20 is provided on the circumference of the upper end of the graphite crucible 8 , and a limiting end plate 21 matching the limiting groove 20 is provided on the circumference of the lower end of the graphite crucible 8 .

[0038] like Figure 6 and 7 As shown, the limiting end plate 21 at the lower end of the upper graphite crucible 8 can be sealed and inserted into the limiting groove 20 of the next graphite crucible 8 to achieve the stacking of the graphite crucibles 8, and due to the setting of the limiting end plate 21 and the limiting groove 20, the graphite crucible 8 set on the rotating table 18 can synchronously drive the stacked graphite crucible 8 at the upper end to rotate.

[0039] The upper circumference of the rotating platform 18 is provided with a receiving groove matched with the limiting end plate 21 .

[0040] like Figure 5 As shown, the limiting end plate 21 at the lower end of the graphite crucible 8 can be placed in the receiving groove on the rotating table 18, and the rotating table 18 is used to drive the graphite crucible 8 to rotate.

[0041] The graphite claw body 17 includes a plurality of waist-shaped leakage holes 26 that are evenly arranged and matched with the leakage holes 24 in interlayer dislocation. The graphite claw body 17 also includes a climbing claw 23 that is attached to the bottom of the graphite crucible 8 and corresponds to the leakage holes 24.

[0042] like Figure 8 As shown, the waist-shaped leakage hole 26 is set at 120° on the graphite climbing claw body 17, and the leakage holes 24 on the graphite crucible 8 are staggered by 120° between layers, ensuring that the material particles fall into the graphite crucible 8 through the waist-shaped leakage hole 26 during the process of falling from the leakage hole 24 to the next graphite crucible 8. During the rotation of the graphite crucible 8, the climbing claw 23 is used to make the material in the graphite crucible 8 fall from the leakage hole 24 after side rotation at a certain angle.

[0043] The discharge valve port 28 adopts a superimposed pneumatic semi-ball valve, and the upper end of the carbonization furnace body is provided with a filling port 6 corresponding to the graphite crucible 8, and one end of the filling port 6 is provided with a furnace top exhaust port 7 communicated with the carbonization furnace body.

[0044] like Figure 2As shown, the discharge valve port 28 adopts a stacked pneumatic semi-ball valve, which is used to control the discharge of materials. The materials are added into the graphite crucible 8 through the injection port 6 on the top of the furnace. Exhaust gas will be generated in the process of carbonization of the materials, and the exhaust gas can be discharged upward through the leakage holes 24. Since the leakage holes 24 in different graphite crucibles 8 are staggered by 120 degrees between layers, the exhaust gas can be spirally climbed to the exhaust port 7 on the top of the furnace without easily escaping upward with the materials.

[0045] A plurality of supporting legs 2 are evenly arranged at the lower end of the frame steel platform 1 .

[0046] like Figure 1 As shown, the supporting legs 2 play a role in supporting and fixing the frame steel platform 1.

[0047] The lower end of the multi-faceted graphite shaft 16 is provided with a fixing rod 19 fixedly connected to the frame steel platform 1, and the fixing rod 19 is resistant to high temperature and has a smooth surface.

[0048] like Figure 5 As shown, the polygonal graphite shaft 16 is fixed to the inner wall of the frame steel platform 1 by using a fixing rod 19 , and the smooth surface of the fixing rod 19 can prevent the material from stagnating on the fixing rod 19 .

[0049] The temperature control system is used to obtain key parameters of the material particles, wherein the key parameters include volume, density, specific heat capacity and initial temperature of the material, and the mass is obtained according to the volume and density. The temperature control system obtains the initial power according to the initial temperature of the material. The temperature control system is also used to obtain the heat loss of the carbonization furnace body, the heat conduction efficiency, the target temperature at the end of the feeding interval 4 and the preheating time, and calculate the material preheating power change index according to the heat conduction efficiency, initial power, preheating time, target temperature, mass, specific heat capacity and initial temperature of the material, wherein the calculation formula is: Among them, Y(XP) represents the material preheating power change index, W(ZL) represents the mass, W(BR) represents the specific heat capacity, M(WD) represents the target temperature, C(WD) represents the initial temperature of the material, Y(RC) represents the preheating time, C(GL) represents the initial power, and R(CD) represents the heat conduction efficiency. The temperature control system adjusts the heating temperature of the feeding compartment 4 in real time according to the material preheating power change index.

[0050] As described above, the present invention obtains the key parameters of the material particles, such as volume, density, specific heat capacity and initial temperature of the material, through the temperature control system, and obtains the mass according to the volume and density. The temperature control system obtains the initial power, the heat loss of the carbonization furnace body, the heat conduction efficiency, the target temperature at the end of the feeding interval and the preheating time through the initial temperature of the material, and calculates the material preheating power change index according to the heat conduction efficiency, initial power, preheating time, target temperature, mass, specific heat capacity and initial temperature of the material. The key parameters such as volume, density, specific heat capacity and initial temperature of the material are obtained through the real-time temperature control system, and the heating process of the material can be dynamically adjusted to ensure that the temperature of each batch of materials is kept constant during the processing process. The system can accurately calculate the required initial power by obtaining the initial state of the material (such as temperature, mass, specific heat capacity, etc.) in real time, and adjust the power output according to the properties of the material. This precise power control helps to avoid excessive energy waste and improve energy efficiency. By considering the heat loss and heat conduction efficiency of the carbonization furnace body, the temperature control system can During the preheating process, energy distribution is optimized to reduce unnecessary heat loss, thereby reducing energy costs. By combining parameters such as target temperature, initial temperature, specific heat capacity, mass and preheating time, the system can accurately calculate the required preheating time and adjust the heating power in real time, which can effectively avoid the problem of overheating or insufficient heating, improve the efficiency of the preheating process, and save time. By calculating the material preheating power change index, the heating strategy can be dynamically adjusted to adjust the heat input according to the actual needs of different materials, thereby avoiding the inadaptability caused by the fixed power setting in the traditional system. By accurately calculating and real-time monitoring the temperature changes of the material, it can ensure that the material is heated and carbonized. The optimal temperature curve is maintained during the production process, which not only improves the quality of the final product, but also shortens the production cycle and improves the overall production efficiency. By presetting and adjusting the target temperature, the temperature control system can prevent the material from burning or structural changes due to overheating, thereby ensuring the quality and consistency of the product. By combining temperature control with the physical properties of the material (such as density, specific heat capacity, etc.), an integrated control system is formed, which can adjust the production parameters according to real-time feedback, thereby realizing the full intelligent management of the production process, solving the problems of inaccurate temperature control, energy waste and low production efficiency in the material preheating process in the prior art, and has broad application prospects and significant economic benefits.

[0051] The temperature control system is used to obtain the radiation heat loss, thermal conductivity, convection heat transfer coefficient, heat exchange area, and temperature characteristics of the carbonization furnace body, wherein the temperature characteristics include the furnace temperature and the ambient temperature, and the conduction heat loss is obtained according to the thermal conductivity, and the convection heat loss is calculated according to the convection heat transfer coefficient, the heat exchange area, the furnace temperature and the ambient temperature, wherein the calculation formula is: D(RS)=D(HX)*R(JM)*[L(WD)-H(WD)]; wherein D(RS) represents the convection heat loss, D(HX) represents the convection heat transfer coefficient, R(JM) represents the heat exchange area, L(WD) represents the furnace temperature, and H(WD) represents the ambient temperature. The temperature control system is also used to obtain the total heat loss according to the convection heat loss, radiation heat loss and conduction heat loss. The temperature control system is also used to obtain the initial power, preheating time, and the required heat at the feeding interval 4, and calculate the heat conduction efficiency according to the initial power, preheating time, required heat and total heat loss, wherein the calculation formula is: Among them, R (CD) represents the heat transfer efficiency, S (RL) represents the required heat, Z (RS) represents the total heat loss, Y (RC) represents the preheating time, and C (GL) represents the initial power.

[0052] As described above, the present invention obtains the radiation heat loss, thermal conductivity, convection heat transfer coefficient, heat exchange area, and furnace temperature and ambient temperature in the temperature characteristics of the carbonization furnace body through a temperature control system, obtains the conduction heat loss according to the thermal conductivity, and calculates the convection heat loss according to the convection heat transfer coefficient, heat exchange area, furnace temperature and ambient temperature. The temperature in the furnace and the ambient temperature are monitored in real time by the temperature control system, and the relevant heat losses (such as radiation heat loss, conduction heat loss and convection heat loss) are calculated. The system can accurately adjust the heating power and temperature control strategy to ensure that the temperature of the material in the graphite crucible changes according to the set curve to avoid overheating or insufficient heating, thereby optimizing the heating process of the material. Due to different materials and operating conditions, the heat loss and heat conduction efficiency will be different. By obtaining the heat loss data in real time, the heating strategy can be flexibly adjusted according to the material characteristics and actual working conditions to avoid uneven heating during the process. When the carbonization furnace is running at high temperature, radiation heat loss is an important source of heat loss. By Real-time monitoring and calculation can adjust the thermal radiation characteristics of the furnace body (such as the thermal emissivity of the furnace body material) during the design and operation process, and reduce radiation heat loss through more precise heating control. Conduction heat loss is determined by the thermal conductivity of the furnace wall. Real-time measurement of the thermal conductivity of the furnace body and calculation of the conduction heat loss can help optimize the furnace structure design (such as the selection of insulation materials, furnace wall temperature control, etc.), and further reduce unnecessary energy loss. Through real-time calculation of the difference between the furnace temperature and the ambient temperature, the heat exchange area and the convection heat transfer coefficient, the convection heat loss can be accurately grasped, so that through reasonable airflow adjustment or insulation design, the convection heat loss can be reduced, and the energy utilization efficiency can be further improved. Through accurate calculation of radiation, conduction and convection heat losses, the heating power and temperature control strategy of the furnace body can be adjusted in real time to make the heating process as efficient as possible. This not only avoids energy waste caused by excessive heating, but also ensures that the material reaches the expected temperature with the lowest energy consumption. Excessive heat loss in a high temperature environment will aggravate the wear and aging of the furnace body.By accurately controlling the temperature and heat loss in the furnace, excessive heat is avoided from being concentrated in unnecessary places, the burden of the furnace material is reduced, and the service life of the equipment is extended. By acquiring and calculating the heat loss data in real time, the temperature control system can automatically adapt to different production stages, material characteristics and environmental changes, and adjust the temperature control strategy. This intelligent adjustment not only improves production efficiency, but also reduces the need for manual intervention and reduces the difficulty of operation. The real-time temperature control system can ensure that the temperature in the carbonization furnace is uniform and stable, thereby ensuring that the heating process of the material in the graphite crucible is more uniform and accurate, and avoiding unstable product quality caused by temperature fluctuations. The present invention obtains the total heat loss according to the convection heat loss, radiation heat loss and conduction heat loss through the temperature control system, obtains the initial power, preheating time, and the required heat at the feeding interval, and calculates the heat conduction efficiency according to the initial power, preheating time, required heat and total heat loss. By accurately calculating the total heat loss (including convection, radiation and conduction heat loss), the heating process can be optimized, and the temperature of the feeding interval can be monitored and adjusted in real time, which can effectively reduce the waste of heat and reduce the energy consumption of the carbonization furnace.For example, reasonable control of heat loss and heat conduction efficiency can ensure that the heat in the heating process is more efficiently transferred to the part that needs to be heated, rather than wasted in unnecessary places. This can improve the overall thermal efficiency of the equipment and reduce operating costs. By real-time monitoring and adjusting the temperature of the feeding compartment, the temperature distribution in the carbonization furnace can be more accurately controlled, thereby improving the uniformity of the carbonization process. This is crucial for high-temperature carbonization processes that require precise temperature control, especially in the high-temperature environment of the graphite crucible. Even a slight change in temperature may have a significant impact on the quality of the final product. By optimizing the temperature control strategy, overheating or uneven cooling can be avoided to ensure stable product quality. By calculating and adjusting the heat conduction efficiency, the heat loss in the furnace can be significantly reduced. In a high-temperature environment, the improvement of heat conduction efficiency means that heat energy is better transferred to the target area rather than being lost through radiation or convection. This not only improves the stability of the temperature in the furnace, but also saves energy. Real-time temperature control helps to adapt to different working conditions and flexibly adjust heat distribution. By accurately calculating the initial power, preheating time and required heat, the control of the preheating stage can be optimized to avoid over-preheating or under-preheating. Reasonable setting of preheating time and power can help speed up production rhythm, shorten production cycle and improve production efficiency. At the same time, by adjusting the feeding interval temperature in real time, production stagnation or quality problems caused by insufficient or overheating can be avoided. By realizing automatic calculation and adjustment of heat loss, heat demand and heat conduction efficiency, the dependence on manual operation can be reduced, making the operation of the vertical continuous high-temperature carbonization furnace equipment more intelligent and automated, which not only reduces human errors, but also improves the reliability of the system, and avoids the problem of inaccurate heat control caused by improper operation. Therefore, the heating process of the vertical continuous high-temperature carbonization furnace equipment can be optimized through accurate calculation and real-time adjustment of temperature control, reducing heat loss, improving heat conduction efficiency, reducing energy consumption, ensuring stable product quality, shortening production cycle, and prolonging equipment life, further improving the intelligence and automation level of the production process.

[0053] The working process of the present invention is as follows: when the present invention is in use, the feeding partition 4, the heating partition 3 and the cooling partition 5 in the furnace of the carbonization furnace body are preheated and heated respectively. Preheating can improve the working efficiency, and the material particles are added into the graphite crucible 8 of the feeding partition 4 of the carbonization furnace body.

[0054] At the same time, the motor 12 drives the first pulley 13 to rotate, the first pulley 13 drives the second pulley 15 to rotate, the second pulley 15 drives the reducer 14 to work, the output end of the reducer 14 drives the rotating column 22 to rotate, the rotating column 22 drives the first gear 10 to rotate, the first gear 10 drives the second gear 9 to rotate, and the second gear 9 drives the rotating table 18 to rotate. Since the graphite crucible 8 is limitedly arranged on the rotating table 18, the limiting end plate 21 at the lower end of the graphite crucible 8 can be placed in the groove on the rotating table 18. Therefore, the rotating table 18 is used to drive the graphite crucible 8 to rotate, and the limiting end plate 21 at the lower end of the upper graphite crucible 8 can be sealed and inserted into the limiting groove 20 of the next graphite crucible 8 to achieve the superposition of the graphite crucible 8. Moreover, due to the setting of the limiting end plate 21 and the limiting groove 20, the graphite crucible 8 arranged on the rotating table 18 can synchronously drive the superimposed graphite crucible 8 at the upper end to rotate.

[0055] The polygonal graphite shaft 16 is fixedly arranged on the inner wall of the frame steel platform 1 by using a fixing rod 19. Since the polygonal graphite shaft 16 fixes the graphite climbing claw body 17 in the graphite crucible 8, when the graphite crucible 8 is rotated, the material flow inside the graphite crucible 8 performs a lateral rotation motion, and the continuously added material flow is guided to achieve a circular motion of the material flow in the horizontal plane of the superimposed graphite crucible 8. The waist-shaped leakage hole 26 is arranged at 120° on the graphite climbing claw body 17, and the leakage holes 24 on the graphite crucible 8 are staggered 120° between layers to ensure that the material particles fall from the leakage hole 24 to the next graphite crucible 8 through the waist-shaped leakage hole 26 and all fall into the graphite crucible 8. During the rotation of the graphite crucible 8, the climbing claw 23 is used to rotate the material flow in the graphite crucible 8 to a specified circumferential angle position. The leakage hole 24 in the graphite crucible 8 flows into the lower layer, and the movement of the material flow realizes the collision, friction and extrusion between the material particles, and the material is evenly heated. The material is heated in the graphite crucible 8 superimposed by the pre-carbonization of the feeding section 4 and simultaneously rotates sideways layer by layer. The material is heated in the graphite crucible 8 superimposed by the high-temperature carbonization of the heating section 3 and simultaneously rotates sideways layer by layer. The material moves to the graphite crucible 8 superimposed by the cooling section 5 and simultaneously rotates sideways layer by layer, and finally rolls into the discharge barrel 11. The discharge of the material is controlled by alternately opening and closing the superimposed pneumatic hemispherical valves. Waste gas will be generated in the process of carbonization of the material, and the waste gas can be discharged upward through the leakage hole 24. Since the leakage holes 24 in different graphite crucibles 8 are staggered by 120° between layers, the waste gas can be spirally climbed to the exhaust port 7 on the top of the furnace without easily escaping upward with the material.
