METHOD FOR MAKING WASTE PLASTIC INTO OIL

摘要

PURPOSE:To provide a method to convert waste plastics into oil by pyrolysis in which non-plastic components can be sorted and separated from wastes without the need for hands and the remaining waste plastics can be converted into hydrocarbon oil continuously and economically. CONSTITUTION:Waste plastics are fed through an inlet in the lower part of a slant extruder, being spirally moved in the cylinder of this extruder under heating, liquefaction and gasification to effect separation into liquefied plastics and solid residues, which are then discharged through a discharge port in the upper part of the cylinder.
