Abstract

"MéTODO E PLANTA PARA A MANUFATURAçãO DE CLìNQUER DE CIMENTO". A presente invenção se refere a um método para a manufaturação de clínquer de cimento (tijolo duro de cimento, tijolo vitrificado de cimento), método pelo qual farinha de matéria prima de cimento é pré-aquecida e queimada em uma planta compreendendo um pré-aquecedor de ciclone (1) e um forno (5). Em concordância com a presente invenção, o referido método está caracterizado pelo fato: - de que pelo menos uma porção da farinha de matéria prima é extraída a partir do pré-aquecedor de ciclone (1); - de que esta farinha de matéria prima é introduzida para uma unidade separada (21) na qual é determinado um tempo de retenção sob condições de oxidação proporcionadas por intermédio de uma corrente de gás para a formação de SO~ 2~ e para expulsão de carbono orgânico; - de que o SO~ 2~ formado e o carbono orgânico expelido são subseq³entemente descarregados a partir da unidade separada (21) entranhados na corrente de gás para o tratamento adicional em um subseq³ente estágio de processo; e de que a farinha de matéria prima é reintroduzida para o pré-aquecedor de ciclone (1). Por intermédio disso, é obtida uma redução efetiva da emissão de VOC, de CO e bem como de SO~ 2~ sem a necessidade de utilização de energia adicional para aquecimento. Pela determinação para a farinha de matéria prima extraída e parcialmente pré-aquecida, de um tempo de retenção sob condições de oxidação separada a partir do pré-aquecedor de ciclone (1), é conseguido que sulfeto irá se oxidar para SO~ 2~ e que carbono orgânico seja expelido a partir da farinha de matéria prima, de maneira que o SO~ 2~, por conseq³ência, formado e o carbono orgânico, por conseq³ência, expelido possam estar entranhados em uma corrente de gás separada, relativamente pequena, e submetidos para o subseq³ente tratamento de uma maneira otimizada. A presente invenção também se refere a uma planta para a realização do método conforme definido em concordância com o anteriormente descrito. Também em concordância com a presente invenção, a referida planta está caracterizada pelo fato de que compreende recursos (13, 15) para a extração de pelo menos uma porção da farinha de matéria prima a partir do pré-aquecedor de ciclone (1); recursos separados (21) para a determinação para esta farinha de matéria prima de um tempo de retenção sob condições de oxidação e, conseq³entemente, assegurar a oxidação, por intermédio de uma corrente de gás, de sulfeto contido nesta farinha de matéria prima para a formação de SO~ 2~ e para a expulsão de carbono orgânico; recursos (17) para descarregar o SO~ 2~ formado e o carbono orgânico expelido a partir da unidade separada (21) entranhados na corrente de gás para o tratamento adicional em um subseq³ente estágio de processo; e recursos (26) para a reintrodução da farinha de matéria prima para o pré-aquecedor de ciclone (1).
