Description

Technical Field

[0001] This application relates to the field of pyrolysis equipment, and in particular to a vertical superconducting transient heat transfer continuous oil refining equipment. Background Technology

[0002] Continuous oil refining equipment is an environmentally friendly system that uses high-temperature pyrolysis technology to convert waste tires into resources such as fuel oil, carbon black, and steel wire through continuous feeding and uninterrupted production. Tire scraps are continuously fed into the system via an automated conveying system, while pyrolysis, oil and gas condensation, and product collection occur simultaneously.

[0003] Existing continuous refining equipment includes feeding equipment, reaction equipment, condensation equipment, and product collection equipment, with the reaction equipment mostly being horizontal reactors. A horizontal reactor mainly consists of a cylindrical furnace body placed horizontally with end caps. The front and rear ends of the furnace body are the feeding end and the discharge end, respectively. Feed is delivered via a conveyor, and the discharge end is manually cleared by pyrolysis. A pushing mechanism within the furnace body allows the tire rubber powder material to move slowly. The reactor is heated by an external heating device to generate heat for pyrolysis, or by directly introducing high-temperature, oxygen-free hot gas into direct contact with the waste tires for pyrolysis.

[0004] However, when using external heating, the horizontal reactor heats from the bottom of the furnace. The uneven residence time of the tire rubber powder material inside the furnace can easily cause blockage, resulting in uneven heat transfer. Furthermore, the uneven residence time of the tire rubber powder material can easily cause local overheating, affecting the efficiency and quality of the pyrolysis reaction. Utility Model Content

[0005] To address the issues of uneven heat transfer and low efficiency in continuous oil refining equipment, this application provides a vertical superconducting transient heat transfer continuous oil refining equipment.

[0006] The vertical superconducting transient heat transfer continuous oil refining equipment provided in this application adopts the following technical solution: A vertical superconducting transient heat transfer continuous oil refining equipment includes a reaction device, a heating device, and a condensation device; the reaction device includes a base and a reaction cylinder; The base is placed on the mounting base surface, and the reaction cylinder is set on the base, with the central axis of the reaction cylinder being vertical; The reaction cylinder includes an inner cylinder and an insulation cylinder. The inner cylinder has a reaction chamber inside, which is used for pyrolyzing tire rubber powder. The top of the inner cylinder is provided with a feed inlet and a steam outlet, and the bottom of the inner cylinder is provided with a slag outlet. The insulation cylinder is wrapped around the outside of the inner cylinder. The heating device includes a superconducting heat layer and a heat source. The superconducting heat layer includes an isolation cylinder and a superconducting heat pipe. The isolation cylinder is disposed in the inner cylinder, and the isolation cylinder and the inner wall of the inner cylinder form a receiving cavity. The superconducting heat pipe is vertically disposed in the receiving cavity, and the central axis of the superconducting heat pipe is parallel to the central axis of the reaction chamber. The superconducting heat pipe is filled with a superconducting heat transfer medium, and one end is an evaporation end. The heat source is disposed outside the reaction chamber, and the heat source heats the evaporation end of the superconducting heat pipe. The air inlet of the condensing device is connected to the steam outlet, and the condensing device is used to condense the pyrolysis steam flowing out of the steam outlet.

[0007] By adopting the above scheme, the reaction device adopts a vertical structure with the central axis of the reaction cylinder vertical. Compared with the traditional horizontal structure, this design allows for a more orderly flow of materials within the reaction chamber. Under the influence of gravity, the materials move from top to bottom, which aligns well with the direction of heat transfer, facilitating uniform heating of the materials within the reaction chamber and reducing localized overheating or insufficient heat transfer. The stable base supports the reaction cylinder, ensuring the overall stability of the equipment and providing a reliable foundation for the continuous oil refining process.

[0008] The reaction chamber inside the inner cylinder is specifically designed for the pyrolysis of tire materials. The feed inlet and steam outlet at the top, and the slag outlet at the bottom, create a rational flow channel for materials and gases. Under the influence of gravity, the tire rubber powder falls smoothly and naturally. Compared to traditional horizontal reaction cylinder designs, this feeding method effectively avoids material blockage, allowing the pyrolysis process to proceed continuously. An insulation cylinder surrounds the inner cylinder, effectively reducing heat loss to the outside during the reaction, maintaining a stable temperature inside the reaction chamber, reducing energy consumption, and improving energy efficiency.

[0009] A superconducting heat pipe is vertically positioned within an inner cylinder surrounding the reaction chamber. The interior contains a superconducting heat transfer medium, and a heat source heats the evaporation end of the heat pipe. The superconducting heat transfer medium possesses exceptional heat transfer capabilities, enabling transient heat transfer. Utilizing the high thermal conductivity of the superconducting heat transfer medium, the heat pipe rapidly and evenly distributes the heat generated by the heat source to all areas of the reaction chamber, allowing the entire reaction chamber to reach and maintain a uniform temperature distribution within a short time, significantly improving the problem of uneven heat transfer. This transient heat transfer characteristic not only improves heat transfer efficiency but also shortens the pyrolysis time of the materials, enabling the equipment to operate at higher efficiency and significantly increasing the production capacity of continuous oil refining.

[0010] The design of the superconducting heat pipe surrounding the reaction chamber constructs a three-dimensional heat transfer system with axial conduction and radial radiation. After the superconducting heat transfer medium heats the evaporation end, it utilizes the near-zero thermal resistance characteristic in the superconducting state to transiently transfer heat to the condensation end, enabling uniform heat radiation in all directions. Combined with the structure of the vertical reaction cylinder, a uniform thermal field is formed, ensuring that the tire material can receive radiant heat from the superconducting heat pipe uniformly in 360° during the descent. This improves heat transfer efficiency, enhances the uniformity and completeness of the pyrolysis reaction, thereby obtaining more high-quality pyrolysis oil, reducing waste residue generation, and improving material utilization.

[0011] The organic integration of the reaction unit, heating unit, and condensation unit forms a highly efficient continuous production system for the entire oil refining equipment. The efficient heat transfer of the heating unit provides a stable and uniform temperature environment for the reaction unit, ensuring the smooth progress of the tire material pyrolysis reaction; the vertical structure and insulation design of the reaction unit, in conjunction with the heating unit, further optimize the pyrolysis process and improve pyrolysis efficiency; the condensation unit promptly condenses and collects the pyrolysis oil flowing out of the steam outlet, ensuring the continuity of the production process.

[0012] Preferably, the device further includes a feeding device, which includes a bucket elevator, a hopper, and a horizontal conveyor. The bucket elevator is located on one side of the reaction device, with its top end connected to the feeding end of the hopper, and both ends of the horizontal conveyor connected to the discharge end of the hopper and the feed inlet.

[0013] By adopting the above scheme, the feeding device, reaction device, heating device, and condensation device form an organic whole, significantly optimizing the continuous oil refining production process. The coordinated operation of the bucket elevator, silo, and horizontal conveyor enables the orderly and efficient flow of materials from the initial conveying stage, matching the vertical structure of the reaction device and the continuous pyrolysis process. Under the action of gravity, the material undergoes pyrolysis from top to bottom through the reaction chamber. The stable material supply provided by the feeding device ensures the continuity of this process. In particular, the setting of the silo for transfer provides buffering and supply compared to direct conveying into the reaction chamber, avoiding energy waste and efficiency reduction caused by reaction stagnation or restart due to feeding interruption. The efficient heat transfer of the heating device relies on a stable material supply. The feeding device ensures that the material enters the reaction chamber at a suitable speed and flow rate, allowing the heat generated by the superconducting heat pipe to exchange heat with the material in a timely and sufficient manner, further improving heat transfer efficiency and pyrolysis effect. Simultaneously, the condenser's ability to stably receive the pyrolysis oil flowing from the steam outlet of the reaction device also benefits from the stable support of the feeding device for the entire production process. Unstable feeding may lead to abnormal pyrolysis reactions, resulting in large fluctuations in the composition and flow rate of the pyrolysis oil, affecting the normal operation of the condenser.

[0014] The feeding device ensures the smooth operation of the entire production system, enabling coordination and collaboration among various units, significantly improving the overall production efficiency and stability of the continuous refining equipment. The automated feeding device can also be integrated with the overall refining equipment control system to achieve intelligent operation. Through sensors and the control system, parameters such as material inventory and conveying speed in the silo are monitored in real time, and the feeding speed and flow rate are automatically adjusted according to the operating status of the reaction unit, making the entire production process more intelligent and precise.

[0015] Preferably, the steam outlet is equipped with a separator, the outlet end of the separator is connected to the inlet end of the condenser, and the outlet end of the condenser is connected to an oil tank.

[0016] By adopting the above scheme, the separator installed at the steam outlet performs targeted separation of the mixed gas discharged from the reaction chamber, effectively solving the problem of high impurity content in pyrolysis oil in traditional oil refining equipment. The separator separates impurities such as solid particles and rubber powder from the mixed gas, allowing only effective components such as pyrolysis oil vapor to enter the condenser, improving the purity of the pyrolysis oil and thus enhancing the quality of the final product. The oil outlet of the condenser is connected to an oil tank, constructing a complete product collection and storage system, solving the problems of inconvenient pyrolysis oil storage and easy production interruption in traditional oil refining equipment. The organic combination of the separator, condenser, and oil tank, together with the reaction unit, feeding unit, and heating unit, constitutes a complete and efficient oil refining system. The separator's purification treatment of the gas produced by the reaction unit lays the foundation for the efficient operation of the condenser; after the condenser converts the pyrolysis oil vapor into liquid, the oil tank stores the product in a timely manner. The three work together to ensure the smooth operation of the entire process of pyrolysis oil from generation, processing to storage. This collaborative working mode is closely related to the stable material supply of the feeding device, the efficient heat transfer process of the heating device, and the orderly pyrolysis reaction of the reaction device, forming a closed-loop production system.

[0017] Preferably, a heat outlet is provided on the bottom side of the inner cylinder, and a hot air furnace is sealed to the heat outlet, which is connected to a buffer tank.

[0018] By adopting the above scheme, the heat outlet located on the bottom side of the inner cylinder dissipates the residual high-temperature heat after the pyrolysis reaction. The connection between the hot blast stove and the buffer tank establishes a stable heat energy storage and supply system. When other production stages require heat energy, the buffer tank can promptly release the stored heat to meet process temperature requirements; when the heat generated by the pyrolysis reaction is less, the stored heat in the buffer tank ensures that production is not affected. Through waste heat recovery and a stable heat energy supply, the energy costs of oil refining production are directly reduced. A stable heat energy supply ensures efficient production operation, reduces equipment failures and production interruptions caused by unstable heat, and lowers equipment maintenance costs and production losses.

[0019] Preferably, the slag outlet is sealed with a spiral sealing discharge device.

[0020] By adopting the above scheme, the spiral-sealed discharge device, through rotating spiral blades, can continuously and stably transport waste residue from the discharge port to the outside, realizing the automation and continuity of the slag discharge process. The propulsion speed of the spiral blades can be flexibly adjusted according to the progress of the pyrolysis reaction and the slag discharge requirements, ensuring timely discharge of waste residue without interfering with the pyrolysis process inside the reaction chamber. This efficient slag discharge method greatly shortens the slag discharge time, reduces production downtime caused by slag discharge, and significantly improves the overall production efficiency of the oil refining equipment. Working in conjunction with the feeding device, heating device, etc., it makes the continuous oil refining process smoother and more efficient. The spiral-sealed discharge device, through special sealing structures such as mechanical seals and packing seals, ensures complete isolation between the reaction chamber and the outside world during the slag discharge process, preventing gas and waste residue leakage. This rigorous sealing design not only ensures production safety but also reduces safety hazards. The organic integration of the spiral-sealed discharge device with the reaction device, heating device, condensation device, and other equipment makes the entire oil refining production process more complete and efficient. In the continuous refining process, the efficient slag discharge capacity of the spiral seal discharge device works in conjunction with the stable feeding of the feeding device, the efficient heat transfer of the heating device, and the rapid condensation of the condensing device to form a complete production closed loop.

[0021] Preferably, a vacuum layer is provided between the inner cylinder and the insulation cylinder.

[0022] By adopting the above scheme, the heat preservation effect of the vacuum layer helps maintain the uniformity and stability of the temperature inside the inner cylinder, avoiding problems such as incomplete reaction and unstable product quality caused by temperature fluctuations. This is beneficial to improving the controllability of the pyrolysis reaction, enabling the reaction to proceed according to the expected process, thereby improving the quality and yield of products such as pyrolysis oil and carbon black, and enhancing the stability and reliability of the entire production process.

[0023] Preferably, an agitation device is provided at the bottom of the inner cylinder. The agitation device includes a rotating shaft tube and blades. The rotating shaft tube is located at the central axis of the inner cylinder. The blades include at least two blades. All the blades are fixedly connected to the rotating shaft tube at a uniform circumferential spacing.

[0024] By adopting the above scheme, the impeller of the agitator rotates under the drive of the rotating shaft tube, which can fully agitate the material placed at the bottom of the inner cylinder. The rotating shaft tube can extend to the outside of the reaction cylinder and is driven to rotate by a motor drive device. The agitator keeps the material in a state of continuous motion, increasing the contact frequency and area between the material and the inner cylinder wall and the superconducting heat pipe. Continuous agitation can prevent the material from sticking to the bottom of the inner cylinder. On the one hand, the material can more fully absorb the heat transferred by the superconducting heat pipe, accelerating the pyrolysis reaction rate; on the other hand, it also promotes heat conduction inside the material, reduces the temperature gradient, and makes the overall heating of the material more uniform.

[0025] In summary, this application has the following beneficial effects: 1. The superconducting heat pipe, equipped with a superconducting heat transfer medium, achieves transient heat transfer thanks to its near-zero thermal resistance. Combined with a honeycomb inner wall that expands the evaporation-condensation interface, it guides efficient circulation of the working medium, allowing heat to radiate evenly from all sides to the center, creating a 360° uniform thermal field. The material moves downwards under gravity, coordinating with the direction of heat transfer, preventing localized overheating or insufficient heat transfer. This significantly improves the uniformity of material heating, shortens pyrolysis time, and reduces energy loss. This design not only improves heat transfer efficiency but also ensures a stable and balanced temperature environment for a complete pyrolysis reaction, reducing waste residue generation and improving the quality and yield of the pyrolysis oil.

[0026] 2. The material is stably conveyed to the reaction cylinder via a bucket elevator and horizontal conveyor, and falls naturally under gravity. The top feed inlet and bottom slag outlet form a non-blocking material channel, avoiding the feeding obstruction problem of traditional horizontal structures. The spiral sealing discharge device continuously discharges slag through adjustable speed spiral blades, and the sealing design isolates external interference, ensuring a stable internal environment in the reaction chamber. The efficient heat transfer of the heating device and the timely collection of the condenser complement each other, seamlessly connecting the feeding, pyrolysis, slag discharge, and condensation stages. Combined with the automated control system, which adjusts the material flow and heating power in real time, a continuous production closed loop of "feeding, reaction, slag discharge, and collection" is formed, significantly reducing energy waste and efficiency loss caused by interruptions.

[0027] 3. The transient heat transfer capability of the superconducting heat pipe provides rapid heating and a uniform thermal field for the vertical reaction vessel, meeting the temperature stability requirements of continuous pyrolysis. The orderly material flow in the vertical structure ensures full utilization of heat and avoids heat transfer dead zones. The stable feed of the feeding device allows the heating device to match the material processing volume in real time. The combination of the condenser and separator ensures the purity and continuous collection of pyrolysis oil. The waste heat recovery system balances heat supply and demand through a buffer tank, reducing energy consumption. Through structural design and device synergy, the entire system achieves multiple improvements in heat transfer efficiency, production continuity, and energy utilization, forming an intelligent and efficient continuous refining system.

[0034] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] Example 1 Embodiment 1 of this application discloses a vertical superconducting transient heat transfer continuous oil refining equipment. (Refer to...) Figures 1 to 2 It includes a reaction device 1, a heating device 2, a condensing device 3, a feeding device 4, and a tail gas treatment device 5.

[0037] For example Figure 1As shown, the reaction apparatus 1 includes a base 11 and a reaction cylinder 12, both of which are cylindrical. The base 11 is fixed to a mounting surface, typically the ground in a factory area, with its central axis vertical. The reaction cylinder 12 is mounted on the base 11, with its central axis collinear with that of the base 11, meaning the reaction cylinder 12 is also vertically mounted, forming a vertical reaction cylinder 12.

[0038] The reaction cylinder 12 includes an inner cylinder 121 and an insulation cylinder 122, with the insulation cylinder 122 wrapping around the outer side of the inner cylinder 121 to form an external insulation layer. The inner cylinder 121 has a cylindrical cavity inside, serving as a reaction chamber 13, where waste tires are pulverized into tire rubber powder, which undergoes a pyrolysis reaction. The top of the inner cylinder 121 has a feed inlet 14 and a steam outlet 15, while the bottom has a slag outlet 16 and a gas outlet 17. A separator 6 is sealed to the steam outlet 15. A heat outlet 18 is located on the side of the middle section of the inner cylinder 121, sealed to a hot air furnace, which is connected to a buffer tank. The slag outlet 16 is sealed to a spiral sealing discharge device 7, and the gas outlet 17 is sealed to a tail gas treatment device 5, which may be a desulfurization tower, etc.

[0039] The heating device 2 includes a superconducting heat layer 21 and a heat source 22. The superconducting heat layer 21 includes an isolation cylinder 211 and a superconducting heat pipe 212. The isolation cylinder 211 is disposed in the inner cylinder 121, and the isolation cylinder 211 and the inner wall of the inner cylinder 121 form an annular receiving cavity 23. The superconducting heat pipe 212 is a straight superconducting heat pipe, and it contains a superconducting heat transfer medium. The central axis of the superconducting heat pipe 212 is parallel to the central axis of the inner cylinder 121. The heat source 22 is used to heat the evaporation end of the superconducting heat pipe 212. In this embodiment, the heat source 22 is a hot air furnace, and the lower end of the superconducting heat pipe 212 is set as the evaporation end. The structure of the superconducting heat pipe 212 is generally composed of three parts: a sealed tubular shell, a capillary wick structure on the inner wall, and a phase change medium. The shell is made of metal materials, such as copper, aluminum, or stainless steel; the inside is evacuated and a suitable amount of working medium, such as water, ethanol, or liquid metal, is injected. The porous wick covering the inner wall, such as sintered metal powder, metal mesh, or a grooved structure, can drive the working fluid circulation through capillary action. Preferably, the wall surface adjacent to the inner wall of the isolation cylinder 211 and the inner cylinder 121 can be designed with a honeycomb structure. This honeycomb structure significantly increases the surface area of ​​the isolation cylinder 211, allowing the heat from the superconducting heat pipe 212 to be transferred to the reaction chamber 13 more quickly. At the evaporation end of the heat pipe, after the working fluid is heated and vaporized, the honeycomb channels guide the vapor to flow rapidly and orderly towards the condensation end. At the condensation end, the condensed liquid working fluid can quickly flow back to the evaporation end through capillary action, forming a highly efficient working fluid circulation system. During tire pyrolysis, the uniform thermal field distribution ensures that all parts of the material are fully and uniformly heated, making the pyrolysis reaction more complete and uniform. This effectively reduces problems such as coking and carbonization caused by localized overheating, improving the quality and yield of the pyrolysis oil. The superconducting heat pipe 212 is based on phase change heat transfer and capillary circulation. At the evaporation end, the working fluid absorbs heat and rapidly vaporizes. The generated steam flows quickly to the condensation end under the action of the pressure difference inside the pipe. The steam releases latent heat at the condensation end and condenses into a liquid state. The liquid working fluid flows back to the evaporation end along the pipe wall under the capillary force driven by the liquid wick, completing the efficient transfer of heat from the high temperature region to the low temperature region.

[0040] The inlet of the condenser 3 is connected to the outlet of the separator 6. Pyrolysis oil gas is transported from the separator 6 to the condenser 3, where it is condensed into pyrolysis oil. The outlet of the condenser 3 is connected to the oil tank 9 to temporarily store the pyrolysis oil produced during condensation. The condenser 3 can employ two sets of oil-gas spray condensers. The oil tank 9 can also be connected to the buffer tank of the hot air furnace via an induced draft fan. The oil gas in the oil tank 9 can be supplied to the buffer tank, and the heat and oil gas buffered in the buffer tank can provide thermal energy for production processes that require a heat source, forming an organically continuous production equipment system. In this application, to ensure continuous production, the oil tank 9 and the buffer tank can include multiple tanks connected in series or parallel. The buffer tank can be continuously connected to the heating system of other production processes to output thermal energy.

[0041] The feeding device 4 includes a bucket elevator 41, a hopper 42 and a horizontal conveyor 43. The bucket elevator 41 is located on one side of the reaction device 1. The discharge end of the bucket elevator 41 is connected to the feeding end of the hopper 42. The two ends of the horizontal conveyor 43 are connected to the discharge end of the hopper 42 and the feed inlet 14 at the upper end of the inner cylinder 121.

[0042] The implementation principle of a vertical superconducting transient heat transfer continuous oil refining device according to an embodiment of this application is as follows: Waste tires are crushed and ground into tire rubber powder by a crushing device. The tire rubber powder is lifted from the lower end by a bucket elevator 41 and transported to a silo 42 above the inner cylinder 121. The tire rubber powder is released from the silo 42 and fed into the reaction chamber 13 through a horizontal conveyor 43 via the feed inlet 14. The tire rubber powder falls naturally from the top of the reaction chamber 13 of the inner cylinder 121 due to its own gravity. The high temperature heating of the superconducting heat pipe 21 causes the tire rubber powder to pyrolyze in the reaction chamber 13, producing a solid mixture of carbon black slag and steel wire, as well as pyrolysis steam containing a gas-liquid mixture of pyrolysis oil. The pyrolysis steam also contains a small amount of carbon black solid particles. The pyrolysis steam enters the separator 6 from the steam outlet 15 at the top of the inner cylinder 121, where the pyrolysis oil and gas are separated. After pyrolysis, the carbon black and waste gas produced are discharged from the inner cylinder 121 through the slag outlet 16 and the gas outlet 17. The spiral sealing discharge device 7, through rotating spiral blades, can continuously and stably transport the waste residue from the slag outlet 16 to the outside, realizing the automation and continuity of the slag discharge process. The propulsion speed of the spiral blades can be flexibly adjusted according to the progress of the pyrolysis reaction and the slag discharge requirements.

[0043] The embodiments of this application have the advantages of achieving fast heat transfer speed, high efficiency, uniform furnace temperature, low power consumption of hot blast stove, and no material blockage in vertical superconducting transient heat transfer continuous oil refining equipment.

[0044] Example 2 This application's embodiment 2 is based on the above embodiment 1, and the difference in this embodiment is that: Figure 3 As shown, an agitation device 8 is provided at the bottom of the inner cylinder 121. The agitation device 8 includes a rotating shaft tube 81 and a blade 82. The rotating shaft tube 81 is located at the central axis of the inner cylinder (121), and the blade 82 includes at least two blades. All blades are evenly spaced and fixedly connected to the rotating shaft tube 81. A vacuum layer 19 is provided between the inner cylinder 121 and the insulation cylinder 122. The vacuum layer 19 hinders heat transfer, thereby improving the insulation effect of the inner cylinder 121, reducing heat transfer to the wall of the inner cylinder 121, and reducing the temperature difference between the inner wall and the center of the inner cylinder 121, thus improving the temperature uniformity within the reaction chamber 13.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
