Pyrolysis reactor

Abstract

This utility model provides a pyrolysis reactor, relating to the field of reactor technology, including a conical gear; a transmission rod fixedly inserted inside the conical gear; and a spiral conveying blade fixedly sleeved on the outer wall of the transmission rod. Driven by the conical gear and the transmission rod, the spiral conveying blade causes the sediment at the bottom of the reactor to rise. In this utility model, through precise linkage of the conical gear transmission system, the spiral conveying blade and the rotating shell form a three-dimensional synergistic mechanism of "vertical lifting - horizontal mixing." The rotating shell drives the stirring paddle to promote horizontal circulation of materials, while the spiral blade forcibly lifts the sediment at the bottom to the top and circulates it vertically. The combined effect of these two mechanisms breaks down concentration and temperature gradients, achieving efficient and uniform mixing of materials and rapid heat transfer within the reactor. This not only significantly increases the contact area of ​​reactants and accelerates the main reaction process, but also prevents sediment accumulation at the bottom through continuous dynamic cleaning, reducing the risk of equipment blockage and extending service life.

Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a pyrolysis reaction vessel. Background Technology

[0002] A reaction vessel is a closed container used to carry out chemical reactions. Its core function is to provide controllable environmental conditions for chemical reactions in order to achieve the conversion of raw materials, the generation of products, or the separation and purification of substances. In pyrolysis reactions, the reaction vessel, as the core device, promotes the thermal pyrolysis of long-chain macromolecular organic matter under high temperature and high pressure conditions, generating small molecule gases, liquid fuels, or solid residues.

[0003] When existing pyrolysis reactors are in operation, the internal liquid is prone to forming a "dead zone" at the bottom of the reactor due to poor fluidity, which leads to heat accumulation, excessively high local temperature, accelerated coking, insufficient contact between the precipitate and the heating medium, resulting in a decrease in reaction rate, uneven product distribution, and the possibility that light components may be over-pyrolyzed to generate gas while heavy components are not completely converted, thereby reducing the recovery rate of the target product. Utility Model Content

[0004] The purpose of this invention is to solve the problem of low recovery rate and reaction rate caused by poor liquid flow during the use of the above-mentioned equipment, and thus proposes a pyrolysis reactor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pyrolysis reactor, including a conical toothed vessel;

[0006] The transmission rod is fixedly inserted inside the second bevel gear. The outer wall of the transmission rod is fixedly fitted with a spiral conveying blade. After the spiral conveying blade is driven by the second bevel gear and the transmission rod, it drives the sediment at the bottom of the reactor to rise.

[0007] A rotating outer shell is movably fitted onto the outer wall of the transmission rod. A set of stirring paddles is fixedly installed on the outer wall of the rotating outer shell for stirring the liquid inside the reaction vessel.

[0008] Conical tooth three is fixedly sleeved on the outer wall of the rotating outer shell. Conical tooth one is meshed between the outer walls of conical tooth two and conical tooth three, enabling the device to synchronously transport and stir the liquid. When conical tooth one is driven, it will drive conical tooth two and conical tooth three to rotate in different directions. When conical tooth two is driven, it causes the internal transmission rod to rotate, which drives the spiral conveying blades on the outer wall to rotate. At this time, conical tooth three begins to drive the internal rotating outer shell to rotate. The rotating outer shell, with the help of a set of stirring blades fixedly installed on the outer wall, can accelerate the mixing of materials in the reactor, so that heat and matter can be transferred rapidly in the reaction system, thereby avoiding local overheating or overcooling. It also allows the reactants to be more evenly distributed in the reactor, reducing the reaction rate differences caused by concentration gradients or temperature gradients, thereby shortening the overall reaction time. At this time, the liquid at the bottom of the reactor that cannot be stirred due to gravity sedimentation comes into the interior of the rotating outer shell through the feed hole and is carried to the top by the spiral conveying blades, and discharged through the discharge hole. This can break the aggregation state of the bottom sediment, further increase the contact area between materials, and avoid uneven reaction caused by local high or low concentrations.

[0009] Preferably, the outer wall of the transmission rod is movably inserted into the interior of the rotating housing. The outer wall of the rotating housing has a set of discharge holes for discharging the lifted liquid, and the outer wall of the rotating housing has a set of inlet holes for facilitating the entry of the bottom sediment liquid.

[0010] Preferably, a rotating shaft is fixedly inserted into the inner wall of the first bevel gear, and one side of the outer wall of the rotating shaft is connected to the output shaft of the motor. A protective cover is fixedly installed on one side of the outer wall of the motor. The protective cover can effectively protect the internal transmission mechanism from damage or increased wear caused by dust or external force, thus extending the service life of the device. After the motor starts, it provides the necessary power to the first bevel gear through the rotating shaft.

[0011] Preferably, the outer wall of the rotating shaft is movably inserted into the inside of the protective cover, the bottom of the protective cover is fixedly installed with the reactor body, and the rotating outer shell is movably inserted into the inside of the reactor body.

[0012] Preferably, the outer wall of the reactor body is provided with a control panel, and the bottom of the reactor body is fixedly connected to a discharge valve. The user can start or stop the reactor body through the control panel. After the work is completed, the internal liquid can be discharged simply by opening the discharge valve.

[0013] Preferably, a support leg is fixedly installed at the bottom of the reactor body, and a feed valve is fixedly connected to the top of the reactor body. The support leg serves as a support frame for the bottom of the reactor body, effectively improving the stability of the reactor body. The feed valve allows users to easily pour raw materials into the feed valve.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, through the precise linkage of the bevel gear transmission system, the spiral conveying blades and the rotating shell form a three-dimensional synergistic mechanism of "vertical lifting-horizontal mixing". The rotating shell drives the stirring paddle to promote the horizontal circulation of materials, while the spiral blades force the bottom sediment liquid to be lifted to the top and circulate vertically. The cross action of the two can break the concentration and temperature gradient, realize the efficient and uniform mixing of materials in the reactor and the rapid heat transfer. This not only significantly increases the contact area of ​​reactants and accelerates the main reaction process, but also avoids the accumulation of bottom sediments through continuous dynamic cleaning, reduces the risk of equipment blockage, and extends service life.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Please see Figure 3 and Figure 4 This utility model provides a technical solution: a pyrolysis reactor, including a conical tooth 10;

[0025] The transmission rod 11 is fixedly inserted inside the bevel gear 10. The outer wall of the transmission rod 11 is fixedly fitted with a spiral conveying blade 17. After the spiral conveying blade 17 is driven by the bevel gear 10 and the transmission rod 11, it drives the sediment liquid at the bottom of the reactor to rise.

[0026] The rotating outer shell 13 is movably sleeved on the outer wall of the transmission rod 11. A set of stirring paddles 15 are fixedly installed on the outer wall of the rotating outer shell 13 for stirring the liquid inside the reactor.

[0027] Conical tooth 12 is fixedly sleeved on the outer wall of the rotating outer shell 13. Conical tooth 9 is meshed between the outer walls of conical tooth 10 and conical tooth 12, enabling the device to synchronously transport and stir liquid. When conical tooth 9 is driven, it will drive conical tooth 10 and conical tooth 12 to rotate in different directions. When conical tooth 10 is driven, it will cause the internal transmission rod 11 to rotate, which in turn drives the spiral conveying blades 17 on the outer wall to rotate. At this time, conical tooth 12 begins to drive the internal rotating outer shell 13 to rotate. The rotating outer shell 13, with the help of a set of stirring blades 15 fixedly installed on the outer wall, can accelerate the mixing of materials in the reactor. The combination of heat and matter allows for rapid transfer within the reaction system, preventing localized overheating or overcooling. It also enables reactants to be more evenly distributed within the reactor, reducing differences in reaction rates caused by concentration or temperature gradients and thus shortening the overall reaction time. At this point, the liquid at the bottom of the reactor, which cannot be stirred due to gravity sedimentation, enters the rotating outer shell 13 through the feed port 16 and is carried to the top by the spiral conveyor blades 17, and discharged through the discharge port 14. This breaks up the aggregation of sediment at the bottom, further increasing the contact area between materials and preventing uneven reaction caused by excessively high or low local concentrations.

[0028] like Figure 3 As shown, the outer wall of the transmission rod 11 is movably inserted into the interior of the rotating housing 13. The outer wall of the rotating housing 13 is provided with a set of discharge holes 14 for discharging the lifted liquid. The outer wall of the rotating housing 13 is provided with a set of inlet holes 16 for facilitating the entry of the bottom sediment liquid.

[0029] like Figure 2 and Figure 3 As shown, a rotating shaft 8 is fixedly inserted into the inner wall of the bevel gear 9. One side of the outer wall of the rotating shaft 8 is connected to the output shaft of the motor 7. A protective cover 6 is fixedly installed on one side of the outer wall of the motor 7. The protective cover 6 can effectively protect the internal transmission mechanism from damage or wear caused by dust or external force, thus extending the service life of the device. After the motor 7 is started, it provides the necessary power to the bevel gear 9 through the rotating shaft 8.

[0030] like Figure 2 and Figure 3As shown, the outer wall of the rotating shaft 8 is movably inserted into the inside of the protective cover 6, the bottom of the protective cover 6 is fixedly installed with the reactor body 1, and the rotating outer shell 13 is movably inserted into the inside of the reactor body 1.

[0031] like Figure 2 As shown, a control panel 2 is provided on the outer wall of the reactor body 1, and a discharge valve 3 is fixedly connected to the bottom of the reactor body 1. The user can start or stop the reactor body 1 through the control panel 2. After the work is completed, the internal liquid can be discharged simply by opening the discharge valve 3.

[0032] like Figure 2 As shown, a support leg 4 is fixedly installed at the bottom of the reactor body 1, and a feed valve 5 is fixedly connected to the top of the reactor body 1. The support leg 4 serves as a support frame at the bottom of the reactor body 1, which effectively improves the stability of the reactor body 1. The feed valve 5 allows users to easily pour raw materials into the feed valve 5.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
