<p>PROBLEM TO BE SOLVED: To separate plastics from the waste plastics in the general and industrial wastes in accordance with their kinds. SOLUTION: Air 10 is introduced into a tower 1a from its lower face, pulsated air 5 is simultaneously introduced from the side face of the tower 1a, and the air 10 and pulsated air 5 are injected into the waste plastics 6 in the lower 1a to form a fluidized bed 2 of the waste plastics 6, the waste plastic 6 are vibrated by the pulsated air 5 introduced from the side face of the fluidized bed 2 so that the waste plastics are separated into a plastic A and a plastic B. The pulsation frequency of the pulsated air 5 and the flow rate of the air 10 and pulsated air 5 are controlled to separate the plastics into the desired kinds. A chlorine-contg. plastic is separated from the waste plastics with high efficiency in this way.</p> |
