PYROLYSIS APPARATUS FOR WASTE PLASTIC

摘要

PROBLEM TO BE SOLVED: To provide a pyrolysis apparatus for a waste plastic installed in a small installation area by composing the apparatus in a small size in spite of capability of sufficient melting and pyrolysis of the waste material of the plastic and efficient treatment. SOLUTION: A first melting cylinder part 16 and a second melting cylinder part 17 of a melting part 3 are connected in series and a first pyrolysis cylinder part 30 and a second pyrolysis cylinder part 33 of a pyrolysis part 5 are mutually connected in series and oppositely arranged in a parallel state with a prescribed interval kept therebetween. The end on the downstream side of the second melting cylinder part 17 and the end on the upstream side of the first pyrolysis cylinder part 30 are connected with a transporting cylinder part 24 and arranged as a whole in a U-shaped state when viewed in a plane. Thereby, the waste plastic can sufficiently be melted and pyrolyzed and miniaturization in the longitudinal direction as compared with the connection thereof in series can be carried out. The space saving of the installation space can be provided. COPYRIGHT: (C)2005,JPO&NCIPI
