Abstract
"PROCESSO E DISPOSITIVO DE TRATAMENTO DOS EFLUENTES DE CéLULA DE ELETRóLISE PARA A PRODUçãO DE ALUMìNIO". A presente invenção refere-se a um processo e a uma instalação de tratamento dos efluentes gasosos produzidos por pelo menos uma célula de eletrólise (1), nos quais os efluentes são encaminhados por pelo menos um conduto (11) em direção aos meios de tratamento (12 - 19) que comportam pelo menos um reator (12) apto a extrair os produtos fluorados contidos nos efluentes por reação com a alumina pulverulenta (16) e um dispositivo de separação (13) apto a separar a alumina proveniente do reator (12) e a fração gasosa residual e comportando meios de filtragem (14). De acordo com a invenção, resfriam-se os efluentes, antes de seu tratamento, por injeção de gotículas de um fluido de resfriamento no(s) conduto(s) de encaminhamento (11), em pelo menos um ponto (P) situado a montante do reator (12), e por vaporização desse fluido. A invenção permite resfriar eficazmente os efluentes de células de eletrólise sem afetar seu funcionamento.
