Abstract

Se divulga una celda de flotacion (1) para tratar particulas suspendidas en suspension y para separar la suspension en un reflujo inferior (400) y un desbordamiento (500). La celda de flotacion comprende un tanque de flotacion (10) con un centro (11), un perimetro (12), un fondo (13) y una pared lateral (14); y una artesa (2) y un pico de artesa (21) que rodea el perimetro (12) del tanque de flotacion. El tanque de flotacion comprende ademas tubos de explosion (4) para introducir la alimentacion de suspension (100) en el tanque, un tubo de explosion que comprende una boquilla de entrada (41), una entrada (42) para gas presurizado, una camara alargada (40) y una boquilla de salida (43). La boquilla de salida se coloca a una distancia vertical (L5) del pico de artesa, la distancia (L5) es de al menos 1.5 m. Ademas, se divulga una linea de flotacion y el uso de la linea de flotacion.A flotation cell (1) is disclosed for treating suspended particles in suspension and for separating the suspension into a lower reflux (400) and an overflow (500). The flotation cell comprises a flotation tank (10) with a center (11), a perimeter (12), a bottom (13) and a side wall (14); and a trough (2) and a trough peak (21) surrounding the perimeter (12) of the buoyancy tank. The flotation tank further comprises explosion tubes (4) for introducing the suspension feed (100) into the tank, an explosion tube comprising an inlet nozzle (41), an inlet (42) for pressurized gas, a chamber elongated (40) and an outlet nozzle (43). The outlet nozzle is placed at a vertical distance (L5) from the trough spout, the distance (L5) is at least 1.5 m. In addition, a waterline and the use of the waterline are disclosed.
