Research on simulation calculation of Tri-Flo heavy-medium cyclone under different structures

Heavy media cyclone has the advantages of real-time on-line controllable density of two-stage sorting, high sorting precision, simple process arrangement, low cost of improvement, etc. The change of its structural parameters has a significant impact on the sorting effect of this equipment. In order to further improve the sorting precision of heavy media cyclone, improve its applicability to the coal washing plant washing process. This paper uses the Fluent software to simulate and analyze the flow fields of the Tri -Flo dense-medium cyclone under different structures. Specifically, with the cylinder diameter remaining unchanged, the axial velocity distribution, static pressure distribution, and tangential velocity distribution of the cyclones with three different structures are analyzed and studied by increasing the core tube and reducing the cylinder diameter respectively. This provides a theoretical and reference basis for the structural design of the Tri-Flo dense-medium cyclone.
