Abstract

"PROCEDIMENTO E DISPOSITIVO PARA RECOLHER E TRATAR OS GASES DE REAçãO DE UMA INSTALAçãO PARA PRODUZIR METAIS FUNDIDOS, BEM COMO UMA INSTALAçãO CORRESPONDENTE PARA REMOVER O Pó". A presente invenção se refere a um procedimento para recolher e tratar os gases de reação provenientes de uma instalação (1) para produzir metais fundidos, sendo que os materiais de carga contendo metal são introduzidos dentro de um recipiente metalúrgico em forma sólida ou líquida e são transformados sob o efeito de combustíveis e materiais reativos, e que os gases de reação quentes que deixam o recipiente metalúrgico sob forma de gases carregados de pó são submetidos parcialmente a um processo primário de remoção do pó e parcialmente a um processo secundário de remoção do pó em dispositivos separadores de pó que lhes são atribuídos. Para poder remover o pó de forma segura de grandes quantidades de gases de reação quentes que se constituem num curto intervalo de tempo, a presente invenção propõe que os gases de reação conduzidos para serem submetidos ao processo secundário de remoção de pó perpassem um acumulador de calor (9) antes do processo de remoção de pó, fazendo com que os gases de reação cuja temperatura exceda a temperatura das paredes dos elementos acumuladores cedam calor ao acumulador de calor, e que este calor acumulado seja novamente transferido aos gases de reação subseqüentes (ou ao ar ambiente aspirado) que apresentam uma temperatura que se encontra abaixo da temperatura das paredes dos elementos acumuladores.
