[Purpose] In order to select appropriate parameters for the disc separator drum and improve the separation performance and efficiency of the separator, [Method] CFX software is used to numerically simulate the internal flow field of the separator drum; the influence characteristics of the drum operating speed, the cone angle of the disc bus and the large end radius of the discs on the separation performance are analyzed using the single variable method and the interpolation method. [Result] The results indicate that increasing the rotational speed and the number of discs will increase the processing capacity of the separator and improve the volume fraction of oil at the outlet of the oil phase; the separation performance will decrease if the cone angle of the busbar is too large or too small, and there is an optimal value of 45°;the large radius of the disc is positively correlated with the processing capacity of the separator, but the growth rate shows a tendency of first increasing and then decreasing. [Conclusion] The research results can provide some references for the selection of drum parameters for disc separators.
