Abstract

Dispositivo para la decantación química física de sólidos, especialmente con el procedimiento de burbujas de gas flotación desde una suspensión con un depósito de decantación esencialmente cilíndrica (12), en la que se ha previsto un reactor de floculación/circulación (20) con simetría de rotación, en el que desembocan excéntricamente por lo menos una entrada de suspensión (24), que introduce la suspensión de entrada en el reactor de floculación (20) y con ello genera un flujo circular, caracterizado porque la entrada de suspensión (24) se ha previsto en la zona superior del reactor de floculación (20) y evacua al flujo circular desde el reactor de floculación (20) tangencialmente de forma radial hacia abajo de a través del perímetro exterior en celdas distribuidoras (44), dispuestas circularmente, que refuerzan la componente tangencial del flujo de suspensión hacia la salida en el depósito de decantación (12).
