Abstract

Un impianto per la separazione ad alta temperatura di contaminanti (B) da materiale plastico (A) di piccola pezzarura o in foglie comprende almeno uno stadio (2) per la separazione dei contaminanti (B) che comprende, a sua volta, un apparecchio separatore (8) di tipo centrifugo atto a separare un flusso (A + B + C) in ingresso costituito da materiale plastico (A), di piccola pezzatura o in foglie, con contaminanti (B) e da un fluido convettivo comprendente acqua e vapore (C) in un flusso principale (A + C) di detto materiale e detto fluido convettivo ed in un flusso secondario (B + C) di detti contaminanti e di detto ftuido convettivo. Il detto stadio di separazione (2) comprende, inoltre, un ciclone (9) atto a ricevere in ingresso detto flusso secondario e a scomporlo in un flusso di scarico di detti contaminanti ed acqua (B + C') ed in un flusso di vapore (C") che viene convogliato verso l'ingresso (18) dell'apparecchio di separazione (8) del medesimo stadio (2) e/o di stadi precedenti. In cascata a tutti i possibili stadi di separazione (2) dell'impianto (1) é inoltre preferibilmente previsto un ultimo ciclone (3) che riceve in ingresso il flusso principale (A + C) in uscita all'ultimo stadio (2) e lo separa a sua volta in un flusso di materiale e acqua (A + C') portato all'esterno dell'impianto e in un flusso di vapore (C') convogliato verso l'ingresso (18) dell'apparecchio di separazione (8) di almeno uno degli stadi (2) che lo precedono.
