Description

Technical Field

[0001] The invention relates to the field of reactors, in particular to a reactor for cyclic pyrolysis based on uniform distribution of medium tube rings. Background Art

[0002] Reactor is a container for chemical reactions. It has the characteristics of corrosion resistance and high temperature resistance. It is usually made of stainless steel, glass, ceramics and other materials. The structure includes the kettle body, kettle cover, stirring device, heating or cooling device, inlet and outlet, etc. Reactor is widely used in the fields of petroleum, chemical industry, medicine, food, materials, etc., for various chemical reactions such as synthesis, decomposition, polymerization, hydrogenation, nitration, etc. In the current environmental protection treatment of solid waste and hazardous waste, most of them are treated by reactors. However, the reactor uses an internal stirring device to mix the reactants evenly, and heats or cools the reactants by electric heating, water circulation heating or oil bath heating to control the reaction speed and temperature. After searching the application number: 201922059343.6, a functional medium circulator is set in the reactor to pyrolyze materials. The significant feature of this patent is that the reactor is provided with sieve holes and a circulation pipe and a ball picking pipe, which can automatically circulate the functional medium used to disperse the material in the reactor to reduce the temperature of the material; However, when the functional medium in the above document is in continuous contact with the material to transfer heat, the temperature of the functional medium will gradually decrease, which will obviously reduce the subsequent heat transfer between the functional medium and the material; and before the material is placed in the reactor, the material is exposed to the outside for a long time, resulting in insufficient heat itself (i.e., cold material). When the functional medium is not too hot, it cannot transfer the high temperature to the cold material when it contacts the cold material; and the circumference inside the reactor is smaller than that outside, and more pipes or functional medium pipes cannot be set to increase the temperature in the reactor. Fewer functional medium pipes will reduce the heating effect of the reactor. In view of this, we propose a reactor based on uniform distribution of medium tube rings for cyclic pyrolysis.

[0018] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] For the embodiments of the present invention, please refer to Figure 1-Figure 8 A reactor for cyclic pyrolysis based on uniform distribution of medium tube rings comprises a support leg 1, a heating furnace 2 is arranged on the top of the support leg 1, limiting plates 3 are arranged at both ends of the heating furnace 2, a reactor 4 is arranged inside the heating furnace 2, a slag discharge structure 700 is arranged inside the heating furnace 2, a heating structure 600 is arranged inside the heating furnace 2, and a material pushing structure 500 is arranged on the side of the heating furnace 2; The functional medium is directed to the heating structure 600 through the reaction kettle 4, and contacts with the material just introduced by the pushing structure 500 to impact, disperse and conduct the temperature; The heating structure 600 is heated by the heating furnace 2, and the heat is discharged from the heating structure 600 and the slag discharge structure 700 into the interior of the reactor 4; The present invention takes into account that the existing functional medium is used to conduct temperature. During the long-term circulation process of transferring temperature to the material, since the temperature of the functional medium is higher than the temperature of the material, the heat will be transferred from the functional medium to the material. As the heat of the functional medium is transferred, the temperature of the functional medium itself will gradually decrease. Therefore, the functional medium pipe 601 is continuously heated by the heating furnace 2. At the same time, the temperature heated by the heating furnace 2 can also be discharged into the reactor 4 from the medium outlet 603. Part of it is to keep the functional medium circulating in the functional medium pipe 601 at a high temperature, and part of it is to further increase the temperature of the stirred material in the reactor 4, which is beneficial to improve the stirring reaction effect of the reactor 4 and improve the temperature transfer effect of the functional medium. Considering that the existing materials are added to the reactor 4 from the outside, but the materials are exposed to the outside for a long time, the heat of the materials themselves will be insufficient. If the functional medium cannot maintain a high temperature state, it will transfer the temperature to the newly entered materials. Then the heat that the materials can absorb is limited. Only when the functional medium maintains a high temperature state and performs heat exchange with the materials can the efficiency of heat exchange be improved, and the subsequent reaction speed of the materials in the reactor 4 can be guaranteed, thereby reducing the subsequent reaction speed of the materials in the reactor 4. Therefore, when the functional medium discharged from the reactor 4 is circulated through the functional medium pipe 601, the heating furnace 2 can heat the functional medium whose temperature is not high inside the functional medium pipe 601 again to a high temperature, and then guide it to the dual-purpose feeding pipe 501 and contact with the newly placed materials to impact and conduct temperature. Part of it is for the impact and dispersion of the materials, so that the materials can be better mixed with the functional medium and conduct temperature later, which is beneficial to improve the reaction speed of the materials after entering the reactor 4 and maintain the material temperature; Next, considering that the circumference inside the existing reactor 4 is smaller than that outside, it is impossible to set more functional medium tubes 601, which will reduce the heating effect of the reactor 4. Therefore, several functional medium tubes 601 are respectively arranged around the center of the reactor 4, and each group is wrapped by the heating furnace 2, so that more functional media can be circulated into the reactor 4, thereby improving the reaction effect and speed of the reactor 4 and improving production efficiency.

[0020] As for the commonly used functional media in the reactor 4, they can be water (water is one of the most commonly used heating media, with the advantages of low cost and easy acquisition. However, water has a low boiling point and will evaporate when the temperature rises to 100°C, so it is not suitable for high-temperature heating. When the temperature requirement is not high, the water heating system is composed of components such as a circulation pump, a water tank, a pipeline and a control valve), heat transfer oil (after the heat transfer oil is heated in the heating pipe, it is transported to the jacket or coil of the reactor 4 through a circulation pump, and heat is exchanged with the inner wall of the reactor 4 to transfer heat to the material in the reactor) and energy balls (energy balls are usually made of special materials, have high density and hardness, and can provide stable physical support and collision effects in the reactor 4. This characteristic enables the energy balls to effectively transfer energy during the reaction process and promote the progress of chemical reactions), etc.; The working principle of the heating furnace 2 and the reactor 4 is well known in the art. The resistance wire or electric heating element in the heating furnace 2 generates heat and dissipates it. The reactor 4 uses an internal stirring device to mix and transport the reactants, and the heating furnace 2 heats or cools the reactants. After the reactor 4 completes the stirring and mixing, the functional medium pipe 601 can circulate the functional medium, and the heating furnace 2 can preheat the circulating functional medium and keep it at a high temperature. On the basis of the above, the following specific structures need to be disclosed in detail: First, to achieve the reaction and mixing of materials and functional media, the following specific structures need to be disclosed in detail. The pushing structure 500 includes a dual-purpose feeding pipe 501, which is fixedly connected to the reactor 4 through the dual-purpose feeding pipe 501. The end of the dual-purpose feeding pipe 501 away from the reactor 4 is fixedly connected to the feeder 502. The diameter of the reactor 4 is smaller than the diameter of the heating furnace 2. As for the setting that the diameter of the reactor 4 is smaller than that of the heating furnace 2, it is to facilitate the subsequent setting of more functional medium tubes 601 outside the reactor 4, avoid occupying the internal space of the reactor 4, and help to improve the high temperature effect of the functional medium; Please refer to Figure 1-Figure 4 , the staff needs to feed the material and the functional medium respectively from the dual-purpose feeding pipe 501, and then start the feeder 502 to generate high-pressure gas, and blow the fed functional medium and material into the reactor 4 to fully mix the material and the functional medium and heat the material.

[0021] The feeder 502 adopts a high-pressure air pump with switchable blowing and suction airflow. The feeder 502 performs blowing in the initial stage to push the medium into the functional medium tube 601 through the pressure difference until the pressure in the functional medium tube 601 and the reactor 4 is balanced. The feeder 502 switches to suction to introduce the medium in the functional medium tube 601 into the reactor 4. The circulation of the functional medium is realized through the reciprocating blowing and suction operations of the feeder 502. Its working principle is as known to those skilled in the art. The low-pressure gas is compressed to a certain pressure and then sent into the pump. The pump further compresses the gas sent by the compressor and pushes it into the cylinder. The pressure in the cylinder can reach a high level of several thousand to tens of thousands of PSI, which is beneficial to improving the subsequent circulation effect of the functional medium.

[0022] In order to keep the functional medium at a high temperature, the following specific structure needs to be disclosed in detail. Please refer to Figure 2-Figure 7 The heating structure 600 includes a functional medium tube 601, which is detachably mounted on the outer annular surface of the reactor 4. The outer annular surface of the functional medium tube 601 is fitted with the heating furnace 2. A right sealing sleeve 602 is provided on the side of the functional medium tube 601 close to the pushing structure 500. The right sealing sleeve 602 is fixedly connected to the dual-purpose feed pipe 501. A plurality of medium outlets 603 are provided on the surface of one end of the reactor 4 away from the dual-purpose feed pipe 501. A grid is embedded inside the medium outlet 603. The surface of the right sealing sleeve 602 is fitted with the functional medium tube 601. When the functional medium circulates, when the material and functional medium inside the reactor 4 are blown to the end near the slag discharge structure 700 by the high-pressure gas generated by the feeder 502, the functional medium will complete the temperature transfer with the material. At the same time, the temperature of the functional medium will decrease. The functional medium after decreasing will separate the functional medium and the slag of the material through the grid embedded in the medium outlet 603, so that the functional medium enters the functional medium pipe 601 under the drive of the high-pressure gas generated by the feeder 502, and the functional medium is guided to the inside of the dual-purpose feed pipe 501. At this time, since the heating furnace 2 wraps a plurality of functional medium pipes 601, Therefore, the heating of the heating furnace 2 is to heat the functional medium guided inside the functional medium pipe 601 and keep it in a high temperature state. On the one hand, the decreasing functional medium is better heated by the heating furnace 2 to prevent the functional medium from being unable to maintain a high temperature state to pyrolyze the material during circulation, thereby improving the temperature transfer efficiency between the material and the functional medium. On the other hand, the functional medium is driven by the high-pressure gas generated by the feeder 502 to enter the reactor 4 again. At the same time, the hot gas from the heating furnace 2 can enter the reactor 4 from the grid embedded in the outlet 603, which is beneficial to improve the pyrolysis rate of the material and the functional medium inside the reactor 4. At the same time, when the functional medium in the functional medium pipe 601 is heated and discharged into the dual-purpose feed pipe 501, it will contact with the material in the dual-purpose feed pipe 501 to impact and disperse the material, so that the material and the functional medium that is always kept in a high temperature state are mixed and the temperature is transferred. At this time, the high-pressure gas generated by the feeder 502 drives the functional medium in a high temperature state to the inside of the reactor 4 to be pyrolyzed with the material again, which can not only complete the circulation of the functional medium, but also keep the functional medium always in a high temperature state; In order to discharge the pyrolyzed material, the following specific structure needs to be disclosed in detail, please refer to Figure 5-Figure 8 The slag discharge structure 700 includes a guide pipe 701, which is fixedly connected to the outer ring surface of the reactor 4. A solenoid valve is provided at the connection between the guide pipe 701 and the reactor 4. A slag outlet 707 is provided on the outer ring surface of the reactor 4. A left sealing sleeve 702 is fitted on the outer ring surface of the guide pipe 701, and a drainage tube 703 is fixedly connected to the bottom of the left sealing sleeve 702. The side of the drainage tube 703 is fixedly connected to the reactor 4, the outer ring surface of the drainage tube 703 is fixedly connected to the slag box 704, the bottom of the slag box 704 is fixedly connected to the slag pipe 706, and the top of the drainage tube 703 is fixedly connected to the air outlet pipe 705; The slag outlet 707 is provided to quickly discharge the slag after pyrolysis, thereby improving the production continuity of the entire device; When the functional medium is directed to the functional medium pipe 601, the solenoid valve (not shown in the figure) provided at the connection between the flow guide pipe 701 and the reactor 4 is in a closed state, on the one hand, to allow the functional medium to flow into the functional medium pipe 601 better, and on the other hand, to block the incompletely pyrolyzed materials; When the functional medium completely pyrolyzes the material, the solenoid valve (not shown in the figure) provided at the connection between the guide pipe 701 and the reactor 4 will be opened, so that the pyrolyzed material will be driven by the high-pressure gas generated by the feeder 502 to flow from the slag outlet 707 to the inside of the guide pipe 701, and then be discharged into the inside of the guide tube 703 and the slag box 704 respectively, and then be discharged from the slag pipe 706 to the collection box (not shown in the figure) placed in advance by the staff, wherein, when the material after the reaction in the reactor 4 is discharged, the functional medium will be carried with it. As for separating the material and the functional medium, other filtering equipment can be used, which is easily associated with the personnel in the technical field, and has nothing to do with the improvement points in the reactor 4, and will not be elaborated here, and then the gaseous matter generated by the pyrolyzed material will be discharged to the external environment from the gas outlet pipe 705; In order to improve the dual-purpose feed pipe 501 to better discharge the functional medium into the reactor 4, the following specific structure needs to be disclosed in detail. The dual-purpose feed pipe 501 passes through the feed port at one end of the right sealing sleeve 602 and is arranged at the same level as the functional medium pipe 601; so as to improve the function medium pipe 601 discharges the heated functional medium and drops into the dual-purpose feed pipe 501 and contacts and impacts with the material just fed; In order to improve the heating of the reactor 4 by the functional medium pipe 601, the following specific structure needs to be disclosed in detail, please refer to Figure 2-Figure 4 , a plurality of functional medium pipes 601 are respectively arranged along the center point of the reactor 4, and the plurality of functional medium pipes 601 are adapted to the medium outlet 603; As for the functional medium pipe 601 and the right sealing sleeve 602, the purpose of providing a plurality of them is to improve the effect of the reactor 4 in transferring temperature and the pyrolysis process, and to prevent the internal circumference of the reactor 4 from being too small to provide more functional medium pipes 601 and thus failing to improve the heating effect of the reactor 4; In order to improve the discharge of slag after pyrolysis, the following specific structure needs to be disclosed in detail, please refer to Figure 5-Figure 8 , a plurality of guide pipes 701 and slag outlets 707 are respectively arranged along the center point of the reactor 4, and the guide pipes 701 and slag outlets 707 are adapted to each other; As for the provision of several guide pipes 701 and slag outlets 707, it is to improve the rapid discharge of slag after pyrolysis and improve the continuity of production of the entire device.

[0023] Working principle: The staff feeds the material and the functional medium from the dual-purpose feed pipe 501 respectively, and then starts the feeder 502 to generate high-pressure gas, and blows the fed functional medium and material into the reactor 4, so that the material and the functional medium are fully mixed, and the material is heated; At this time, the solenoid valve (not shown in the figure) provided at the connection between the flow guide pipe 701 and the reactor 4 is in a closed state, so the material and functional medium inside the reactor 4 are blown to the position close to the slag discharge structure 700 by the high-pressure gas generated by the feeder 502, and the functional medium will complete the temperature transfer with the material. At the same time, the temperature of the functional medium will decrease gradually. The functional medium after decreasing will separate the functional medium and the slag of the material through the grid embedded in the medium outlet 603, so that the functional medium enters the functional medium pipe 601 under the drive of the high-pressure gas generated by the feeder 502, and the functional medium is guided to the inside of the dual-purpose feed pipe 501. At this time, since the heating furnace 2 wraps a plurality of functional medium pipes 601, the heating of the heating furnace 2 heats the functional medium guided inside the functional medium pipe 601 and keeps it in a high temperature state. At the same time, the hot gas from the heating furnace 2 can enter the reactor 4 from the grid embedded in the medium outlet 603, which is beneficial to improve the pyrolysis rate of the material and functional medium inside the reactor 4. At the same time, when the functional medium in the functional medium pipe 601 is heated and discharged into the dual-purpose feed pipe 501, it will contact with the material in the dual-purpose feed pipe 501 to impact and disperse the material, so that the material and the functional medium that is always kept in a high temperature state are mixed and the temperature is transferred. At this time, the high-pressure gas generated by the feeder 502 drives the functional medium in a high temperature state to the inside of the reactor 4 again to be pyrolyzed with the material again; When the functional medium completely pyrolyzes the material, the solenoid valve (not shown in the figure) provided at the connection between the guide tube 701 and the reactor 4 will be opened, so that the pyrolyzed material will be driven by the high-pressure gas generated by the feeder 502 to flow from the slag outlet 707 to the inside of the guide tube 701, and then discharged into the drainage tube 703 and the slag box 704 respectively, and then discharged from the slag pipe 706 to the collection box (not shown in the figure) placed in advance by the staff, and then the gaseous substances generated by the pyrolyzed material will be discharged to the external environment from the gas outlet pipe 705.
