Abstract

In this study, based on the current situation of waste drilling fluid treatment, the operating parameters of micro cyclones are investigated. A 10-mm micro cyclone used to separate ultrafine particles was designed and the effect of the split ratio on the pressure and axial velocity in the micro cyclone as well as the total separation efficiency was investigated using CFD techniques. The conclusions obtained are that the pressure gradient in the microcyclone increases with the increase of the splitting ratio; the axial velocity decreases with the increase of the splitting ratio; the total separation efficiency increases with the increase of the splitting ratio.
