Theoretical and experimental research on pressure drop ratio prediction model of de-oiling hydrocyclone

The correlation between energy dissipation and split ratio in a 35 mm diameter de-oiling hydrocyclone was established by experiment. under the conditions of different overflow orifice diameters, as long as the split ratio is less than 25%, energy dissipation was a constant. It only changed with inlet flow rate. When the inlet flow rate was 30, 40, 50, 60, 70 L&middotmin-1, the energy dissipation is about 10, 30, 80, 140, 205 N&middotm&middots-1 respectively. Based on this characteristics of hydrocyclone and theoretical analysis, a prediction model of de-oiling hydrocyclone was proposed. The prediction of pressure drop ratio was identical with the test data.
