Method of plastics degradation and the installation for degradation of plastics

摘要

The method and apparatus of degradation of plastics, the method consisting in that not purified and not segregated raw-material - plastic waste - is being grinded, and the charge material received as a result of grinding, with continuous feeding is being introduced into the volume feeder (8), which then with continuous feeding doses the charge material on the conveyor (10) situated in the chamber (3) of the degradation machine (1), the conveyor (10) relocates plastic under the area of heating (6), and its speed is adjusted in such a way that plastic waste under degradation at any moment do not contact the heater surface and/or the assembly of heaters and/or the wall of the chamber (3) of the degradation machine (1). The relocated plastic is subjected to plasticization and changes its state of aggregation, and hydrocarbon particles contained in it change their state of aggregation into liquid, and next - gaseous one, and are then passed into the distillation column (2), and organic and inorganic impurities contained in the charge mass as well as coked plastic are being removed from the conveyor (10) into the waste tank (18).
