Wet Cyclone内の圧力損失

抄録

The pressure drop in the wet cyclone is an important item together with its performances, because the pump, which is used for the wet cyclone, must be selected according to the pressure drop, and the necessary energy depends upon the pressure drop and the liquid quantity.
The author has measured the pressure difference between the inlet and the overflow pipe under the various operating conditions.
The influences of the following factors upon the pressure drop were investigated:(1) Feed inlet velocity, (2) Diameters of vortex finder, underflow nozzle and cylindrical portion, (3) Size of inlet nozzle, (4) Height of cyclone, (5) Inserted length of vortex finder, (6) Types of feeding, (7) Pulp density of feed slurries.
From the above experimental results, author showed that the pressure drop through the wet cyclone may be represented by the formula (4·2).
