Abstract

EL POLVO DE FACTORIAS METALURGICAS ES TOMADO DE UNA PRIMERA ATMOSFERA DE HORNO, CON PREFERENCIA A TEMPERATURAS DESDE 1.000 A 1.100 NTINUA HASTA QUE ESPECIALMENTE LOS ALCALINOS Y COMPUESTOS DE PLOMO HAN SIDO VIRTUALMENTE EVAPORADOS A PARTIR DEL POLVO. LA EXPERIENCIA MUESTRA QUE ESTO TOMA UNA HORA. UNA CORRIENTE DE GAS FLUIDO SE ALIMENTA DENTRO DE LA ATMOSFERA DEL HORNO DE TAL MODO QUE EL VALOR PLOMO-CLORO-ALCALINOS SE TOMA A PARTIR DEL HORNO DE TUBO ROTATIVO A UNA INSTALACION DE CONDENSACION Y FILTRACION. SE AÑADEN AGENTES REDUCTORES, ESPECIALMENTE CARBON AL POLVO DE LA FACTORIA METALURGICA, QUE ES TOMADO DE OTRA ATMOSFERA CALIENTE DE HORNO, ESPECIALMENTE A 1.150 HASTA 1350 INUAMENTE AGITADO. ESTO REDUCE EL OXIDO DE ZINC EN EL POLVO, MIENTRAS QUE EL POLVO PERMANECE EN EL HORNO HASTA QUE HA SIDO EVAPORADO SUSTANCIALMENTE TODO EL ZINC COMO VAPOR DE ZINC METALICO A PARTIR DEL POLVO DENTRO DE LA ATMOSFERA DE HORNO CONTENIENDO OXIGENO Y EL ZINC METALICO HA SIDO CONVERTIDO A OXIDO DE ZINC. LA EXPERIENCIA MUESTRA QUE ESTO TOMA MAS DE DOS HORAS. DE AQUI, ADEMAS, UNA CORRIENTE DE GAS FLUIDO SE ALIMENTA A LA ATMOSFERA DE HORNO Y TOMA EL OXIDO DE ZINC FUERA DEL HORNO Y DEL GAS FLUIDO CON EL OXIDO DE ZINC ENFRIADO Y FILTRADO.
