Abstract

SE PRESENTA UN SISTEMA PARA SECAR LODOS HUMEDOS QUE INCLUYE UN SECADOR (1) COMO COMPONENTE PRINCIPAL. EL SECADOR ESTA COMPUESTO DE UNA SECCION INFERIOR PARA LA FLUIDIZACION DE GAS (11) Y UNA SECCION SUPERIOR DE FLUIDIZACION DE ALTA VELOCIDAD (12). EL LODO HUMEDO A SECAR SE INTRODUCE EN EL INTERIOR DE UNA MEZCLADORA (3) EN LA CUAL CADA PARTICULA SE RECUBRE CON EL LODO HUMEDO, Y LAS PARTICULAS RECUBIERTAS SE SUMINISTRAN A LA SECCION DE FLUIDIZACION DE GAS (11). LAS PARTICULAS FINAS EXPELIDAS DE LA SECCION DE FLUIDIZACION DE GAS SE FLUIDIZAN EN LA SECCION DE FLUIDIZACION DE ALTA VELOCIDAD (12) MIENTRAS SE SECAN MEDIANTE ELEMENTOS CALENTADORES. DESPUES DE LA FINALIZACION DE LA OPERACION DE SECADO, LAS PARTICULAS DE LODO SECAS SE RECOGEN EN UN RECOLECTOR DE POLVO (2). SUBSECUENTEMENTE, LAS PARTICULAS FINAS DE LODO SECO SE LLEVAN HASTA UNA UNIDAD RECOLECTORA DE POLVO EN FORMA DE BOLSA (4) DESDE DONDE SON DESCARGADAS A UNA TOLVA (6). UNA PARTE DE LAS PARTICULAS GRUESAS DE LODO SECO RECOGIDAS EN ELRECOLECTOR DE POLVO SE SUMINISTRA A LA SECCION DE FLUIDIZACION DE GAS, UNA PARTE DE LAS MISMA SE SUMINISTRA A LA MEZCLADORA (3)PARA MEZCLARSE CON EL LODO HUMEDO, Y EL RESTO SE SUMINISTRA A LA TOLVA (6). EL GAS EXPELIDO POR LA UNIDAD RECOLECTORA DE POLVO EN FORMA DE BOLSA (4) SE INTRODUCE EN LA SECCION DE FLUIDIZACION DE GAS COMO GAS FLUIDIZADO. UNA PARTE DEL GAS EXPELIDO SE EXTRAE AL EXTERIOR EN UNA CANTIDAD SUBSTANCIALMENTE IGUAL A LA DEL GAS VAPORIZADO PROVENIENTE DEL LODO HUMEDO.
