<p>A thermal regeneration method of waste rubber, comprises: adding a feedstock of waste rubber raw powder, environmentally-friendly softener and powdery adjuvant into an agitating heater, wherein the weight ratio thereof is 100/8~150/20~l500, firstly heating under oxygen insulation condition, then introducing into an agitating cooler and cooling to l00? or less, discharging so as to obtain the product; or a part or all of powdery adjuvant in the feedstock is not added to the agitating heater together with other components in the feedstock at the same time, but is added to the agitating heater before discharging the feedstock which was added to the agitating heater previously, and/or is added while introducing the heated feedstock into an agitating cooler; or introducing a pre-formulated feedstock into a screw extruder, cooling the feedstock to l00? or less after passing the heating section, mixing section, then discharging so as to obtain the product. Optionally, the said thermal regeneration method has multi-direction transfer relationship on feedstock and energy with well-known pyrolysis of waste rubber or plus a process for preparing carbon black from the flammable fuel or flammable gas.</p> |
