Pyrolitic reactor for waste plastic

摘要

A pyrolytic reactor (10) for waste plastic can treat a remarkably increased amount of waste plastic to dechlorinate it throughout its service life. The pyrolytic reactor (10) for waste plastic comprising a reactor shell (16) having a waste plastic inlet port (26) arranged at a first end and a hydrogen chloride outlet (30) and a molten plastic outlet port (32) arranged at a second end opposite to said first end, a heating means (14) arranged between said waste plastic inlet port (26) and said hydrogen chloride outlet port (30) to heat the waste plastic in the reactor shell (16) from the outside and a guide means (20) for guiding the waste plastic in the reactor shell (16) from said first end toward said second end is characterized by further comprising a molten plastic return flow-path (18) for holding a molten plastic draw-out port (36) arranged at said second end and a molten plastic feedback port (34) arranged at said first end in communication with each other and an internal heating means (42) for internally heating the waste plastic in the reactor shell (16).
