Description

Technical Field

[0001] This utility model relates to the field of thermal pyrolysis technology, and in particular to a thermal pyrolysis electromagnetic heating module. Background Technology

[0002] Waste materials generated during the manufacturing process of plastic fibers, plastic products, and other related industries, as well as waste plastics collected by recycling plants, are subjected to pyrolysis in an anaerobic or anaerobic environment. This process involves heating long-chain organic compounds to break their molecular bonds, ultimately decomposing them into smaller molecular structures as byproducts (such as fuel oil) and water. Pyrolysis technology involves feeding waste plastics into an oiling facility, where they undergo pyrolysis, vaporization, condensation, separation, and distillation to obtain plastic pyrolysis oil. This oil is then further processed through distillation and condensation to convert it into liquid or gaseous fuel oil for industrial use.

[0003] For general thermal decomposition treatment, please refer to [link / reference]. Figure 1 As shown, the waste plastic is mainly fed into the feed port 11 of a feeding device 10 and conveyed by a conveying screw 12. The outer periphery of the conveying screw 12 is equipped with an electric heater 13, which can be fed into the feed port of a thermal cracking reactor 20 and enter the thermal cracking reaction chamber 21. A heating device 22 is provided on the periphery of the thermal cracking reaction chamber 21, and an oil output pipe 23 is provided on the upper part of the thermal cracking reaction chamber 21 to discharge the gas and cracked oil after cracking. A conveying pipe 24 is provided at the bottom of the thermal cracking reaction chamber 21 to discharge the carbon black produced after the thermal cracking reaction.

[0004] Thus, the waste plastic is conveyed by the conveying screw 12 of the feeding device 10 at the feeding end and enters the pyrolysis reaction chamber 21. Using pyrolysis technology, the waste plastic undergoes a pyrolysis reaction under the high temperature and oxygen-deficient conditions of the pyrolysis furnace. The carbon black produced after pyrolysis is discharged out of the furnace through the conveying pipe 24 at the discharge end. At this time, the oil and gas can be discharged through the oil output pipe 23. The electric heater 13 can provide heating for the feeding device 10. The electric heater 13 is generally directly wound with copper wire on the feeding device 10. When the electric heater 13 is damaged, it is generally impossible to determine the point of damage, and the whole set needs to be replaced instead of a partial replacement. Moreover, once the electric heater 13 is damaged, it is necessary to rewind the wire on site, which greatly increases the difficulty of processing.

[0005] Furthermore, the pyrolysis reactor 20 can provide heating to the pyrolysis reaction chamber 21 through the heating device 22. The heating device 22 is generally wrapped with copper wire around the outer diameter of the pyrolysis reactor 20. When the heating device 22 is damaged, it is generally impossible to determine the point of damage, and the whole unit needs to be replaced instead of a partial replacement. Moreover, once the heating device 22 is damaged, it is necessary to wind the wire on-site, which greatly increases the difficulty of its processing. Utility Model Content

Detailed Implementation

[0027] To achieve the above-mentioned technical objectives, the structural content and features of this utility model will be described in detail below with reference to the accompanying drawings. It is believed that this will enable a further understanding of the content of this utility model and its effects.

[0028] Please see Figures 2 to 8 As shown, the pyrolysis electromagnetic heating module of this utility model mainly includes a primary pyrolysis machine 30 and a pyrolysis reaction body 40, wherein:

[0029] A primary pyrolysis machine 30 is provided, wherein a cylindrical machine body 32 is mounted on a frame 31. A feed hopper 321 is provided at the front of the machine body 32, which can be used to feed waste plastic conveyed by a conveyor belt into the machine body 32. A heat-conducting layer 33 is covered on the outer diameter of the machine body 32, and a first heating device 34 is provided outside the heat-conducting layer 33. The first heating device 34 is composed of multiple bendable sheet-shaped electromagnetic modules 341, and a discharge pipe 35 is connected to the end of the machine body 32.

[0030] A pyrolysis reactor 40 is provided with a feed inlet 41, which is connected to the discharge pipe 35 of the primary pyrolysis machine 30, and can allow molten plastic waste to enter the pyrolysis reaction chamber 42. A second heating device 43 is provided on the periphery and bottom of the pyrolysis reactor 40. The second heating device 43 is composed of multiple bendable sheet-shaped electromagnetic modules 431. An oil output pipe 44 is provided at the top of the pyrolysis reaction chamber 42 to discharge the gas and pyrolysis oil after pyrolysis. A conveying pipe 45 is provided at the bottom of the pyrolysis reaction chamber 42 to discharge the carbon black produced after the pyrolysis reaction.

[0031] In this way, waste materials generated during the production process of plastic fiber and plastic product manufacturing industries, as well as waste plastics recycled by resource recycling plants, are conveyed by conveyor belt to the feed hopper 321 of the body 32 of the primary pyrolysis machine 30 and enter the body 32. During the conveying process of the waste plastics in the body 32, the heat-conducting layer 33 covering the outer diameter of the body 32 is heated by the first heating layer 34 (the temperature is controlled at 100℃~280℃), so that the waste plastics in the body 32 can be gradually decomposed while being conveyed, and can reach the melting stage at the end of the body 32 (that is, the waste plastics become fluid), and are discharged from the discharge pipe 35.

[0032] The discharge pipe 35 discharges fluid waste plastic, which enters the pyrolysis reaction chamber 42 through the inlet 41 on the pyrolysis reactor 40. The temperature is heated to 300°C to 800°C by the second heating device 43 installed around the periphery and bottom of the pyrolysis reactor 40. The fluid waste plastic heats the long-chain organic compounds, causing their molecular bonds to break. Finally, it decomposes into smaller molecular structures, achieving the production of gas and pyrolysis oil, which is output through the oil output pipe 44. The carbon black produced by the pyrolysis is concentrated at the bottom of the pyrolysis reaction chamber 42 and is discharged by a conveying pipe 45.

[0033] Thus, this utility model can achieve the following:

[0034] (1) The first heating device 34 of the initial stage pyrolysis machine 30 is composed of multiple electromagnetic modules 341 and the second heating device 43 of the pyrolysis reactor 40 is composed of multiple electromagnetic modules 431. By setting the electromagnetic modules, electromagnetic heating that converts electrical energy into heat energy using the principle of electromagnetic induction can provide a heating method with fast heating speed, high energy efficiency and stable temperature.

[0035] (2) The first heating device 34 of the initial stage pyrolysis machine 30 is composed of multiple electromagnetic modules 341 and the second heating device 43 of the pyrolysis reactor 40 is composed of multiple electromagnetic modules 431 on the periphery and bottom. By setting multiple electromagnetic modules in the form of bendable plates, when the electromagnetic module is repaired or damaged, only the damaged single electromagnetic module needs to be repaired or replaced, without having to replace the entire first heating device 34 or the second heating device 43, thus reducing maintenance costs.

[0036] (3) The first heating device 34 of the initial stage pyrolysis machine 30 is composed of multiple electromagnetic modules 341 and the second heating device 43 of the pyrolysis reactor 40 is composed of multiple electromagnetic modules 431. By setting multiple electromagnetic modules in the form of bendable sheets, when the electromagnetic module is damaged, the operator can make various shapes according to different needs through mold design. The electromagnetic module can be wound and manufactured in the factory according to the required shape and specifications, and then assembled on site, which can reduce processing time and inconvenience of on-site construction.

[0037] The above-described present invention is merely an example of the preferred embodiment. Those skilled in the art can make various modifications and implementations, but all such modifications and implementations should be included within the spirit and scope of the present invention.

[0038] In summary, this utility model, through electromagnetic heating and the installation of an electromagnetic module, provides stable heating, single-piece replacement, and in-factory processing, thereby reducing maintenance and repair costs and achieving environmental protection and energy-saving effects. Its structural changes and functional improvements are beyond doubt. Furthermore, this utility model was not published or publicly used before the application, and thus meets the requirements for a patent application. Therefore, a patent application is filed in accordance with the law.
