Full analysis of the process flow of waste tire pyrolysis equipment

Waste tires are piled up like mountains, and black pollution is becoming increasingly serious. However, pyrolysis equipment is transforming these wastes into valuable resources with its efficient conversion capacity. So, how does pyrolysis equipment achieve this green transformation?
Thermal conversion in an oxygen-free environment. The core principle of pyrolysis equipment is to decompose the rubber polymers in tires into small molecular compounds through high temperature (usually 260°C to 800°C) in an oxygen-free or oxygen-deficient environment. The whole process can be divided into five key steps: the whole or shredded tires (3-5cm in size) are fed into the sealed reactor through a hydraulic feeder or a screw conveyor to ensure the airtightness of the system. The reactor is heated by fuel oil or non-condensable gas, and the temperature gradually rises to above 260°C, triggering rubber cracking. This stage is precisely controlled by the PLC system. In the optimal cracking range of 280°C-320°C, the rubber molecular chain breaks and generates a mixed oil and gas. The application of micro-negative pressure technology can improve safety and conversion efficiency. The high-temperature oil and gas are cooled step by step through the vertical and horizontal multi-stage condensation system, and the liquid oil is collected and stored; the uncondensed gas is recovered through the water seal device and fed back to the heating system as fuel to achieve energy circulation. The residual carbon black (accounting for 35%-38% of the raw materials) and steel wire (about 15%) are discharged through the automatic sealing slag discharge system. The steel wire is recovered by magnetic separation, and the carbon black can be further processed into industrial raw materials.
Modern pyrolysis equipment integrates dust removal and exhaust gas purification devices to ensure that the flue gas is discharged in the form of "white water vapor" in compliance with the standards. Its ultimate value lies in the full quantification of resources: 40% fuel oil, 38% carbon black, 15% steel wire and 7% combustible gas, achieving 100% conversion of waste tires!
With the breakthrough of continuous pyrolysis technology, pyrolysis equipment is becoming a key fulcrum of the circular economy - not only to cure "black pollution", but also to transform waste into industrial blood, injecting strong impetus into sustainable development.
