The main treatment modes of the waste tire include retreading, rubber powder, regenerated rubber, burning, pyrolysis and the like. At present, the oil preparation by pyrolysis is internationally recognized as the most potential treatment mode for the resource utilization of waste tires. But the scrap tire cleaning pyrolysis technology is still in the experimental stage for a long time.

(II) activation: high-temperature activated gas is sent into the activation section 4 from the high-temperature activated gas inlet 7 and is in direct contact with carbon black, the high-temperature activated gas provides a high-temperature background environment and an activating agent for the activation of the carbon black, the activated high-quality carbon black is recovered after being discharged from the activated carbon black outlet 8, and the residual high-temperature combustible gas is sent into the pyrolysis section 2 through the gas-solid conveying channel 3 to provide energy for the pyrolysis of subsequent waste tire particles.
The high-temperature activated gas is high-temperature combustible gas after incomplete combustion.
The invention has the beneficial effects that:
(1) clean continuous pyrolysis replaces traditional high-pollution intermittent pyrolysis, and the total reaction time, labor and energy consumption are greatly reduced.
(2) The pyrolysis and the activation are carried out at intervals, so that the carbon black after the pyrolysis can be greatly modified, and the economic value of the carbon black is improved.
