Abstract

Patente de Invenção:<B>"PROCESSO E DISPOSITIVO PARA AERAçãO DE DISPERSõES"<D>. A invenção refere-se a um processo para aeração de dispersões, particularmente para flotação, por exemplo, na remoção de tinta de suspensões de matéria fibrosa, no qual estão previstos pelo menos dois estágios. Ela está caracterizada, predominantemente, pelo fato de que em cada estágio está prevista uma circulação de líquido próprio, separada, que aspira e mistura o gás ou o ar. Além disso, a invenção refere-se a um dispositivo com pelo menos duas células de flotação, no qual em cada estágio está previsto um injetor 2 próprio, que está unido com uma bomba associada a uma circulação de líquido 1.
