LIQUEFYING APPARATUS

摘要

A conversion-to-oil apparatus is not provided with rotary members in a heating unit and in a decomposing unit in the process of changing plastic into oil, a residue tank and catalyst, wherein plastic gel is fed into a first buffer tank 2 including a cylinder disposed vertically, a second buffer tank 3 including a cylinder disposed vertically and finally a vaporizing vessel 4 including a cylinder 4a disposed laterally, a liquid surface L·S in the vaporizing vessel 4 being adjusted at a diagonal center position in the vertical direction of the cylinder by controlling both the feeding amount of plastic gel and the temperature of the liquid surface so as to be a temperature of 400° C. to 410° C., so that the rotary members, the residue tank and the catalyst become unnecessary to make the structure of the apparatus compact.

主权项

1. An apparatus for converting plastic into oil in which the plastic is heated to be melted so as to vaporize molten plastic in a process of thermal decomposition, which comprises:
an extruder for extruding plastic gel produced by melting the plastic; a buffer tank for staying the plastic gel therein extruded from the extruder at a predetermined temperature for a predetermined time; and a vaporizing vessel for storing molten plastic fed from the buffer tank to vaporize the molten plastic so as to produce plastic gas from a liquid surface of the molten plastic, the vaporizing vessel having a large vaporizing area therein, the temperature of which is adjusted.
