Abstract
There is provided a centrifugal separator for solid-liquid separations. The centrifugal separator comprises (a) an accelerator rotatable at an angular velocity, ω about an axis, and having an inside surface with a point on the axis, and (b) a nozzle for introducing a feed stream at a volumetric flow rate (Q) into the accelerator via an orifice. The orifice is substantially centered about the point, and the orifice has an inner diameter (d) within the range of approximately 0<d≦4δ, where δ=1.414 [(4Q/π2ω)1/3].
Claims8
A centrifugal separator for shear-sensitive solid-liquid separation, comprising:
- a centrifuge bowl for containing fluids therein;
- an accelerator rotatable at an angular velocity (ω) about an axis, having an inside surface with a point on said axis and and is couple to the centrifuge bowl;
- and
- a nozzle for introducing a feed stream at an volumetric flow rate (Q) into said accelerator via an orifice, wherein said orifice is substantially centered about said axis, point, and wherein said orifice has an inner diameter (d) within the range approximately:
- 1δ≦0<d≦4δ,
- where δ=1.414.
