THERMAL DECOMPOSITION APPARATUS FOR MIXED PLASTIC WASTE

摘要

PROBLEM TO BE SOLVED: To provide a small-sized thermal decomposing apparatus having a simple handleability capable of efficiently thermally decomposing a mixed plastic waste containing polyethylene terephthalate(PET). SOLUTION: A tank type reactor 12 is installed under a stirring type reactor 11. A mixed plastic waste containing PET is brought into contact with steam in the stirring type reactor 11 while being stirred together with a filler 13 and the PET is hydrolyzed. PE, etc., are melted and preliminarily decomposed by the stirring type reactor 11 into a molten plastic, dripped into a tank type reactor 1 below and thermally decomposed. A thermal decomposition bas is taken out from a thermal decomposition gas output port 18 between the stirring type reactor 11 and the tank type reactor 12.
