The production process flow comprises the following steps: the pyrolysis temperature of the tire is 120-380 ℃, the pyrolysis furnace is operated by adopting the external heating, micro negative pressure and anoxic pyrolysis process, the furnace body is closed, the gas is ensured not to leak in the production process, the pyrolysis efficiency is improved, and meanwhile, the unsafe hidden trouble and secondary pollution caused by the gas leak in the production process are fundamentally eliminated. The main raw materials of the technology are outsourced clean junked tires, pretreatment procedures such as cleaning, crushing, steel wire drawing and the like are not needed, the junked tires directly enter the pyrolysis furnace automatically under the spiral action of the rotary pyrolysis furnace, and the feeding process is high in automation degree, safe, convenient, time-saving and labor-saving. Since the cracking process is a complex physicochemical reaction process, the cracking process is performed in multiple stages according to the chemical reaction process mentioned in the tire cracking principle. The specific cleavage process is as follows:
1. when the cracking temperature is between 0 and 150 ℃, an equipment exhaust valve is opened to slowly exhaust air in the thermal cracking furnace 1, an anaerobic condition of the cracking process is realized, and as the thermal cracking process is just started, the waste wheel needs to conduct heat absorption and heat transfer processes at the stage, so that the waste wheel needs to be slowly heated at the stage, generally at the rate of 2K/min, and when the temperature reaches about 120 ℃, the temperature in the furnace is found to be maintained for a period of time without obvious heating phenomenon, and at the moment, a great amount of waste tires begin to absorb heat, the thermal cracking reaction process gradually begins, and pyrolysis gas and oil begin to be generated. This stage is typically around 2 hours.
2. When the cracking temperature is between 150 and 380 ℃, closing an exhaust valve to start collecting oil, gas and other products generated by pyrolysis, and enabling high-temperature flue gas to enter two oil-water separators connected in series to realize separation of the flue gas and heavy oil; then the oil product is collected in the oil tank through a condenser; the generated combustible gas is connected to a combustion chamber for combustion, so that heat is provided for the pyrolysis process; in order to prevent too severe pyrolysis, the temperature of this stage still needs to be raised slowly, generally about 4 hours, and in order to prevent the combustible gas from burning too fast, which results in too high temperature raising rate, it is necessary to control the flow of the combustible gas, and store the excess combustible gas for the pyrolysis process of the next stage.
3. When the pyrolysis temperature range is 380 ℃ in the constant-temperature reaction process, the pyrolysis process at the stage is similar to the process at the second stage, the process flow is still carried out, the generation of combustible gas at the stage is gradually reduced, and when the heat value provided by the combustible gas is insufficient, the biomass fuel needs to be supplemented to maintain the heat of the pyrolysis process. This stage typically takes about 2 hours.
4. And the pyrolysis is completed in a cooling stage, heating is stopped in the process, the project adopts an air cooling mode, the heat of the outer wall of the furnace body is continuously taken away through the air draft of the fan 22, and the duration of the cooling section is about 8 hours. When the furnace body is cooled to 120 ℃, steam is introduced into the cracking furnace chamber to drive out residual cracking gas in the furnace and the residual cracking gas is introduced into the waste gas combustion chamber to burn out, and the duration of driving away the cracking gas is about 10min. At this time, the carbon black screw conveyor was started, and the pyrolytic carbon black was collected. After the carbon black is collected, an evacuation valve above the furnace body is opened, the normal pressure in the furnace is recovered, the tank body is opened, and the pyrolysis steel wire is automatically discharged under the spiral action on the furnace wall. This stage generally takes about 2-4 hours and then fills with new junked tires, followed by the above-described cracking process. Because the tire in this technical scheme is whole tire when feeding, does not have cutting broken workshop section, and the furnace body is constantly rotated in the schizolysis process, so steel wire kink together when the ejection of compact, the small amount of carbon black that is stained on the steel wire just can fall through the tapping, and the direct packing outward transport after the steel wire ejection of compact. Then the steel wire outlet is closed, the carbon black discharge outlet (the diameter is about 0.4 m) is opened, the steel wire outlet is in butt joint with a closed spiral slag extractor, carbon black (the particle size is about 80-100 meshes) is discharged and then directly enters into a packaging bag, and the packaging bag is packaged and leaves a factory after being weighed by a platform scale. The discharge time of the carbon black steel wire of each equipment is 2 hours respectively. The total time for the entire tire lysis procedure was 20 hours.
The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
