Title:
METHOD AND FACILITY FOR THE DISPOSAL OF PLASTICS WASTE
Document Type and Number:
WIPO Patent Application WO/2007/069449
Kind Code:
A1
Abstract:
The invention aims at reducing the volume of plastics wastes of various forms, particularly
medical plastics waste containing a large amount of used bulky articles such
as films or containers, nearly steadily and continuously and thereby recovering
fuel oil efficiently. The invention relates to a disposal facility (1) for plastics
waste which is provided with a volume reduction plant (2) and a pyrolysis plant
(8). The volume reduction plant (2) is constituted of a treatment tank (3), a superheated
steam feeder (4), and a screw feeder (5) for the treatment tank. The superheated
steam feeder (4) is constituted of the first superheated steam feeder (4a) for
feeding superheated steam into the treatment tank (3) and the second superheated
steam feeder (4b) for feeding superheated steam to the inside of the shaft of the
screw feeder (5) though the shaft tip and ejecting the superheated steam toward
the outside of the shaft which is filled with the substance to be treated from the
inside of the shaft. The substance to be treated is melted by the superheated steam
ejected from the second superheated steam feeder (4b), fed into the pyrolysis
plant (8), and gasified therein through pyrolysis. Thus, fuel oil is recovered.
