Abstract

EN UN PROCESO Y UN DISPOSITIVO, UNA SUSPENSION DE CELULOSA DE FINA CONSISTENCIA, CUYA TASA DE CONSISTENCIA Y FLUJO SE CONOCEN, SE DIRIGE AL LADO DE SUCCION DE UNA BOMBA PRINCIPAL (4), EN CUYO LADO DE PRESION ESTA ACOPLADA EN SECUENCIA UNA PRIMERA UNIDAD DE HIDROCICLON MULTIPLE (6) PARA LIMPIAR LAS IMPUREZAS PESADAS, UNA SEGUNDA UNIDAD DE HIDROCICLON MULTIPLE (7) PARA LIMPIAR LAS IMPUREZAS LIGERAS, Y UNA CAJA DE CABEZA DE COMPUERTA (8) PARA UNA MAQUINA DE AGUA O UNA MAQUINA DE PAPEL (9). ESTO PROPORCIONA, POR UN LADO, LIMPIEZA Y PRODUCCION DE PULPA O PAPEL ININTERRUMPIDA MEDIANTE ALMACENAMIENTO INTERMEDIO, Y POR OTRO LADO, UN ESPESOR DE LA PULPA EN LA SEGUNDA UNIDAD DE HIDROCICLON MULTIPLE DE UNA CONSISTENCIA APROPIADA PARA ESPARCIR SOBRE UNA MALLA METALICA O SIMILARES.
