Abstract

Patente de Invenção: <B>"PROCESSO DE REMOVER SóLIDOS DE GRANULAçãO RELATIVAMENTE GROSSA DE UM LEITO FLUIDIFICADO ESTACIONáRIO"<D>. De acordo com a invenção, um gás de fluidificação é introduzido para cima dentro do leito fluidificado (3) através de uma grade de válvula (2), o dito leito fluidificado estacionário (3) contendo sólidos com diferentes tamanhos de grão. Um tubo de suprimento (10) está disposto na área do leito fluidificado, a boca do tubo sendo localizada acima da grade de válvula (2) e sua saída (12) levando para fora do leito fluidificado (3). Parte dos sólidos localizados acima da grade de válvula (2) é soprada dentro do tubo de suprimento por um jato de gás (13) que é direcionada para cima e alimentada separadamente do gás de fluidificação e pneumaticamente evacuada do leito fluidificado através do tubo de suprimento (10). Normalmente, a velocidade de fluxo do gás no tubo de suprimento é pelo menos duas vezes maior do que a velocidade do gás de fluidificação no leito fluidificado.
