Abstract

EN UN METODO PARA LA CONVERSION DE UNA SUSPENSION DE FIBRA, Y ESPECIALMENTE PARA INCREMENTAR LA EFICACIA DE UN APARATO DESHIDRATADOR, ESPECIALMENTE PARA PULPA DE FIBRA RECICLADA; EL RESIDUO DEL APARATO DESHIDRATADOR ES TRATADO EN UN FRACCIONADOR, DONDE SE REALIZA UN FRACCIONAMIENTO EN LIQUIDO, Y LAS FRACCIONES SE INTRODUCEN SELECTIVAMENTE EN EL FLUJO DE RECEPCION DEL APARATO DESHIDRATADOR. EN UN APARATO PARA PRACTICAR EL METODO, UN FRACCIONADOR (10) DEL TIPO EN EL QUE EL FRACCIONAMIENTO SE LLEVA A CABO EN LIQUIDO ESTA CONECTADO A LA SALIDA DE RESIDUOS (8) DE UN APARATO DESHIDRATADOR (1), Y LAS SALIDAS DE FRACCIONAMIENTO (18,19,20) DEL FRACCIONADOR LLEVAN A LA SALIDA DE RECEPCION (6) DEL APARATO DESHIDRATADOR.
