[0026] See also Figure 1 and Figure 3 An embodiment of the present invention is: a green recycling solid waste tire pyrolysis carbon resource utilization device, the top of the base 1 is equipped with a front-to-back arranged support block 2, the support block 2 is installed with a hydraulic cylinder, the pyrolysis module includes a pyrolysis furnace 3 movably installed on the output end of the hydraulic cylinder, the pyrolysis furnace 3 is a double-layer structure, the outer layer structure of the pyrolysis furnace 3 is filled with heat medium, the back of the pyrolysis furnace 3 is plugged with a scraper 10, the front of the pyrolysis furnace 3 is equipped with equidistantly arranged storage barrels 16, the storage barrel 16 is installed with a servo motor, the output end of the servo motor is equipped with a stirring rod 17, and the stirring rod 17 is located inside the scraper 10.

[0027] Furthermore, the solid waste tire first enters the pyrolysis furnace 3, which usually adopts an indirect heating method.

[0028] See also Figure 1 , Figure 2 and Figure 7 , an embodiment provided by the present invention: a green recycling solid waste tire pyrolysis carbon resource utilization device, a storage box 5 is installed on the top of the base 1, and the top of the storage box 5 is penetrated with evenly arranged storage holes, the activation module includes an activation tank 6 arranged in two groups of storage holes, the modification module includes a plasma reaction tank 7 arranged in another group of storage holes, the bottom of the activation tank 6 and the plasma reaction tank 7 are both installed with a discharge pipe, and the outer surface of the discharge pipe is installed with a solenoid valve, the two groups of activation tanks 6 are respectively used for oxidation activation and microwave activation of pyrolytic carbon, a conveying component 8 is installed on the top of the activation tank 6, and the conveying component 8 is used to pump the pyrolytic carbon in one group of activation tanks 6 into the other group of activation tanks 6, a storage groove is provided on one side of the outer wall of the storage box 5, and storage frames 9 arranged equidistantly are placed inside the storage groove, and the storage frame 9 is located below the discharge pipe, and the conveying component 8 is an automatic suction machine, and the automatic suction machine is equipped with a monitoring system, and the monitoring system uses a camera and a sensor technology to monitor the activation of the pyrolytic carbon in the activation tank 6.

[0029] Furthermore, when performing the activation operation, the pyrolytic carbon is firstly subjected to an oxidation activation operation, thereby removing the deposits on the surface of the pyrolytic carbon and improving the quality of the pyrolytic carbon. When the microwave activation operation is required, the pyrolytic carbon in one group of activation tanks 6 is adsorbed by the conveying assembly 8 and conveyed to another group of activation tanks 6. Then, the pyrolytic carbon after the oxidation activation can be subjected to a microwave activation operation in the other group of activation tanks 6, so that the pyrolytic carbon is placed in a microwave field. Then, under the action of microwaves, the dipoles inside the pyrolytic carbon will vibrate, and the heat generated will cause the local temperature of the pyrolytic carbon to rise, thereby inducing changes in the internal structure of the pyrolytic carbon, making the pores of the pyrolytic carbon more developed, and improving the adsorption capacity of the pyrolytic carbon. In addition, the activated pyrolytic carbon can be applied to the field of electrode materials to improve the ion propagation channel. After the activation treatment, it can be selected whether to perform a modification operation according to the direction of pyrolytic carbon recycling and reuse. If necessary, the pyrolytic carbon is sent to the plasma reaction tank 7 for modification operation, otherwise the treatment of the pyrolytic carbon is completed. If the pyrolytic carbon needs to be applied to the field of electrode materials, the pyrolytic carbon needs to be further modified. The pyrolytic carbon is placed in the plasma reaction tank 7, and then the plasma generator is started. Under the set parameters, the pyrolytic carbon is allowed to react with active substances in the plasma such as oxygen atoms, ozone and free radicals. During the reaction process, the highly active oxygen species in the plasma will react chemically with the carbon atoms on the surface of the pyrolytic carbon, and oxygen-containing functional groups such as hydroxyl, carboxyl, carbonyl, etc. are introduced on the surface of the pyrolytic carbon. After the reaction is completed, the modified pyrolytic carbon is post-processed under an appropriate environment. For example, the by-products produced during the reaction are cleaned and removed, and then dried and stored.

[0030] After pyrolytic carbon is modified by plasma oxidation, the oxygen-containing functional groups on the surface can promote the adsorption and diffusion of electrolyte ions. For example, in the electrode materials of supercapacitors, these functional groups can serve as active sites of pseudocapacitance to increase the specific capacitance of the electrode. At the same time, the interfacial compatibility between the modified pyrolytic carbon and the electrolyte is improved, reducing the interfacial resistance and improving the adsorption of pyrolytic carbon.

The common separation device 4 includes a cyclone separator, which uses the principle of centrifugal force to separate the pyrolytic carbon particles from the pyrolysis gas and part of the entrained pyrolysis oil vapor. Under the action of centrifugal force, the pyrolytic carbon particles fall along the wall of the cyclone separator and are collected in the collection bin at the bottom, while the pyrolysis gas and pyrolysis oil vapor in the pyrolysis furnace 3 and the cyclone separator enter the condenser, where the pyrolysis oil vapor is cooled and liquefied and separated from the pyrolysis gas, and the separated pyrolysis oil and pyrolysis gas enter their respective storage containers, thereby facilitating the subsequent purification and recovery operations of the collected pyrolysis gas and pyrolysis oil.
