Reactor for separating aluminium from multi-layer film materials

Abstract

Disclosed is a reactor for separating an aluminum layer from multi-layer film wastes to reuse a multi-layer film waste without burying or incinerating the multi-layer film waste including the aluminum. The reactor comprises a cylindrical casing which is filled with a solution to dissolve aluminum layers of the multi-layer film wastes pulverized into a predetermined size, a partition dividing an inner portion of the casing into a reactor tub in which the solution reacts with the aluminum layer and a separator tub which is provided at a portion of the reactor tub to decompose the pulverized multi-layer film wastes in which the aluminum is completely dissolved by the solution, and a stirrer which is installed at an upper portion of the reactor and stirs the solution in the reactor to activate the reaction between the solution and the aluminum in the reactor tub and to transfer the multi-layer film wastes to the separator tub. The partition is spaced apart from a bottom of the casing to form a passage between the bottom of the casing and the partition, and the reactor tub communicates with the separator tub through the passage.
