Abstract

PROCEDIMIENTO PARA SECADO Y ACONDICIONAMIENTO DE POLIMERIZADOS DE ESTIROL EXPANDIBLES Y DISPOSITIVO PARA LA REALIZACION DEL PROCEDIMIENTO. LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA SECADO DE POLIMERIZADOS DE ESTIROL EXPANDIBLES, CON ELIMINACION PREVIA DE AGUA, CON UN DIAMETRO DE GRANO MEDIO ENTRE 0,1 Y 3,0 MM EN UN PROCESO DE DOS ETAPAS. EN UNA PRIMERA ETAPA DE PROCESO SE CONSIGUE EL SECADO EN UN SECADOR DE CORRIENTE CON ALTA CARGA DEL PRODUCTO EN ZONA DE TEMPERATURA ENTRE 20 Y 40 DESPUES DE LA SEPARACION DEL POLIMERIZADO ESTIROL SE LLEGA A UNA SEGUNDA ETAPA DE PROCESO EN DONDE SE MEZCLA EN UN APARATO DE TRATAMIENTO POSTERIOR PARA SECADO Y AJUSTE DE UNA DISTRIBUCION REGULAR DE LA MEZCLA DEL MEDIO DE IMPULSION CON FONDOS DE VENTILACION Y AIREACION DISPUESTOS DE FORMA ALTERNATIVA, A TRAVES DE LOS CUALES EL POLIMERIZADO ESTIROL LLEGA DESDE UNA ENTRADA DEL PRODUCTO A UNA SALIDA DEL PRODUCTO. LOS FONDOS DE DESAIREACION Y VENTILACION CONTIENE ABERTURAS DE GAS QUE SE MUESTRAN HACIA ABAJO.
