Abstract

"MéTODO E INSTALAçãO DE LEITO FLUIDIFICADO PARA O TRATAMENTO TéRMICO DE SóLIDOS CONTENDO TITâNIO". A presente invenção refere-se a um método e a uma instalação para o tratamento térmico de sólidos contendo titânio e possivelmente óxidos de metal adicionais, no qual os sólidos granulados finos são aquecidos para uma temperatura de 700 a 950<198>C em um reator de leito fluidificado (1). Para melhorar a utilização da energia, é proposto introduzir um primeiro gás ou mistura de gás por debaixo através de um tubo de abastecimento de gás (3) para dentro de uma câmara de mistura (7) do reator (1), o tubo de abastecimento de gás (3) sendo pelo menos parcialmente circundado por um leito fluidificado anular estacionário (10) que é fluidificado pelo abastecimento do gás de fluidificação. As velocidades do gás do primeiro gás ou mistura de gás, bem como do gás de fluidificação para o leito fluidificado anular (10) são ajustadas tal que os números de partícula Froude no tubo de abastecimento de gás (3) ficam entre 1 e 100, no leito fluidificado anular (10) entre 0,02 e 2 e na câmara de mistura (7) entre 0,3 e 30.
