The multi-stage pyrolysis technology adopted by the tire refining equipment is an efficient and environmentally friendly solution for waste tire treatment. Its core process and advantages are as follows:
Anaerobic cracking ‌ : In a slightly positive pressure anaerobic environment of 280-550℃, through precise temperature control, rubber macromolecules are broken, generating cracking oil (35-50%), carbon black (30-40%), steel wire (20%), and combustible gas ‌
Youdaoplaceholder0 Staged condensation ‌ : The oil and gas produced by cracking are separated through a multi-stage condensation system (such as a tubular condenser), and the light oil and heavy oil are recovered according to the temperature gradient to improve the purity of the fuel oil ‌
Youdaoplaceholder0 tail gas recycling ‌ : Non-condensable gases are purified and then used as fuel to return to the reactor, achieving energy self-sufficiency.
