Abstract
"PROCEDIMENTO E DISPOSITIVO PARA RECICLAR BANHOS DE DECAPAGEM DE METAL". A presente invenção se refere a um procedimento para reciclar banhos de decapagem de metal, incluindo os seus respectivos banhos de enxág³e e dispositivos de purificação do ar evacuado, caracterizado por: a) Antes da reciclagem, efetuar a transformação dos ácidos livres presentes nos fluxos de resíduos líquidos a serem tratados para a forma de sais metálicos; b) Separar a água da solução de sais metálicos obtida, sendo esta substancialmente isenta de ácidos, para obter uma solução de sais metálicos concentrada; e c) Conduzir a solução concentrada de sais metálicos por um processo térmico para produzir óxidos metálicos e ácidos livres. Um dispositivo correspondente também é objeto da presente invenção. Por meio do dispositivo e do procedimento em conformidade com a presente invenção, o grau de obtenção de ácidos bem como a produção de óxidos metálicos podem ser substancialmente ampliados mantendo simultaneamente baixos custos de operação.
