Abstract
LA INVENCION SE APLICA EN METALURGIA DE METALES NO FERROSOS Y PERMITE OBTENER UNA EXCELENTE RECUPERACION DE METALES NO FERROSOS A PARTIR DE DESECHOS METALURGICOS Y DE MATERIAS PRIMAS DE RECUPERACION, CON UN MENOR CONSUMO DE COMBUSTIBLE Y REDUCIENDO LA CANTIDAD DE POLVO CONTENIDO EN LOS GASES DE ESCAPE. DE ACUERDO CON DICHO PROCEDIMIENTO, BASANDOSE EN PARAMETROS DE TRATAMIENTO PREESTABLECIDOS, SE OBTIENE UNA CARGA FORMADA POR MATERIAL QUE CONTIENE ZINC, UN COMPONENTE PULVERULENTO DE COMBUSTIBLE SOLIDO Y UN ACTIVADOR, EN LA RELACION 8-12:2,5-7:0,8-1,5. LA CARGA SE MEZCLA Y SE GRANULA. LOS GRANULOS OBTENIDOS, DE 1-30 MM DE DIAMETRO Y UN CONTENIDO DE HUMEDAD DEL 16-18 %, Y EL RESTO DEL COMBUSTIBLE SOLIDO NECESARIO PARA EL PROCESO, SE DOSIFICAN MEDIANTE UN PROGRAMA PREESTABLECIDO DE CONTROL TECNOLOGICO, EN LA PROPORCION 3:1, Y SE ALIMENTAN A UN HORNO DE WAELZ. A CONTINUACION SE INSUFLA OXIGENO EN UNA CANTIDAD DE 3-12 M SUP,3 /T DE CARGA TRATADA, EN EL EXTREMO DE DESCARGA DE LOS HORNOS. LOS GASESQUE SALEN DE LOS HORNOS Y QUE CONTIENEN METALES NO FERROSOS, SE ENFRIAN Y PASAN POR UN FILTRADO EN DOS ETAPAS, EN UN SISTEMA DE FILTRACION. EL CONTENIDO EN POLVO DE LOS GASES DE ESCAPE TRAS LA PRIMERA ETAPA PUEDE ALCANZAR LOS 350 MG/NM SUP,3 Y, TRAS LA SEGUNDA ETAPA, DESCIENDE HASTA MENOS DE 10 MG/NM 3 . LOS OXIDOS METALICOS RECOGIDOS EN LOS FILTROS SE GRANULAN EN GRANULOS DE 2-6 MM DE DIAMETRO Y DE UN CONTENIDO EN AGUA DEL 13,6 AL 16 % Y, A CONTINUACION, SE SOMETEN A UN TRATAMIENTO TERMICO EN UN HORNO TUBULAR, EN CUYA EXTREMIDAD DE DESCARGA SE INSUFLA OXIGENO EN UNA CANTIDAD DE 5-12 M 3 /T DE OXIDOS. LOS OXIDOS METALICOS TOSTADOS SE SOMETEN A UN NUEVO TRATAMIENTO HIDROMETALURGICO Y LOS GASES DEL HORNO SE ENFRIAN, SE HACEN PASAR A TRAVES DE UN SISTEMA DE FILTRACION Y LOS OXIDOS METALICOS RECOGIDOS SE ENVIAN PARA UNA LIMPIEZA Y RECUPERACION SUPLEMENTARIAS, TRAS LAS CUALES LOS GASES EVACUADOS CONTIENEN 4-8 MG/NM 3 DE POLVO.
