Abstract

Procedimiento para la recuperación pura de cloruro de polivino (PVC) de mezclas desmenuzadas previamente que contienen PVC y otros residuos de plástico así como eventualmente impurezas, tales como partículas de arena, metal, papel y/o tejidos, donde: a) la mezcla es ablandada en un agente hinchador para PVC, b) el PVC hinchado es desmenuzado mecánicamente y c) es separado de los restantes plásticos y de las eventuales impurezas y d) los pasos citados y todos los restantes del procedimientos tales como secado o similares, se llevan a cabo en un sistema cerrado, caracterizado porque la mezcla reblandecida es transportada a presión a una disposición de como mínimo dos hidrociclones (15, 24) conectados en serie, en el primer hidrociclón (15) se separa en la corriente descendente una fracción pesada de impurezas tales como partículas de arena y de metal y partículas de plástico pesadas, y en la corriente ascendente una fracción ligera de partículas de PVC hinchadas e impurezas y partículas de plástico ligeras, después se clasifica por tamaños de partícula la fracción ligera depurada previamente de este modo y la fracción de partículas más pequeñas con las partículas de PVC hinchadas y partículas de plástico más pequeñas se llevan al segundo hidrociclón (24), en el cual se separan las partículas de PVC en la corriente descendente.
