Abstract

SE PROPONE UN PROCEDIMIENTO PARA DEPURAR SUSPENSIONES DE YESO, ESPECIALMENTE SE SUSPENSIONES DE YESO DEL LAVADO HUMEDO DE UNA INSTALACION DE DESULFURACION DE GASES DE HUMO. LA SUSPENSION DE YESO (9) ES CONDUCIDA A UNA PRIMERA ETAPA DE HIDROCICLON (1), QUE TRABAJA CON UNA ALTA CONCENTRACION DE FLUJO INFERIOR (11) Y CUYO FLUJO SUPERIOR (10) ES LLEVADO A UN TANQUE-DEPOSITO (2). EL FLUJO INFERIOR (11) DE LA PRIMERA ETAPA DE HIDROCICLON (1) SE DILUYE EN UN TANQUE DE SUSPENSIONES (3) EN UN CONTENIDO MENOR DE SUSTANCIA SOLIDA, LLEVANDOLO A CONTINUACION A UNA SEGUNDA ETAPA DE HIDROCICLON (4), CUYO FLUJO SUPERIOR SE INTRODUCE TAMBIEN EN EL TANQUE-DEPOSITO (2). EL YESO, CONTENIDO EN EL FLUJO INFERIOR (14) DE LA SEGUNDA ETAPA DE HIDROCICLON (4), SE DESHIDRATA INMEDIATAMENTE Y SE SEPARA DEL PROCESO, EN DEPENDENCIA DE LA PUREZA DEL YESO OBTENIDA O NECESARIA, O BIEN SE CONDUCE ANTERIORMENTE A UNA O VARIAS ETAPAS DE HIDROCICLON CONECTADAS ANALOGAMENTE. EL FLUJO SUPERIOR (15) COMUN A LA PRIMERA Y A LA SEGUNDA Y/O OTRAS ETAPAS DE HIDROCICLON ES CONDUCIDO A TRAVES DEL TANQUE-DEPOSITO (1) A UNA TERCERA ETAPA DE HIDROCICLON (6). EL FLUJO SUPERIOR (17) DE LA TERCERA ETAPA DE HIDROCICLON (6) ES LIBERADO EN UN ESPESADOR (8) DE LAS PARTICULAS DE SUSTANCIA SOLIDA, UTILIZANDOSE EL FLUJO ACLARADO (23) PARA LA DILUCION EN EL TANQUE DE SUSPENSIONES (3).
