Influence of Underflow Diameter on Flow Field Characteristics and Separation Performance of Cyclone Separator

Lihong Wei

Abstract


To explore the impact of varying bottom outlet diameters on the flow characteristics and separation performance of a 70mm prima_x005fry diameter cyclone separator, we analyze cyclone separators with bottom outlet diameters of 10mm, 12mm, 14mm, and 16mm. The findings
reveal that at an inlet velocity of 10m/s and for particle sizes ranging from 10 to 90 μm, cyclone separators with different bottom outlet diameters exhibit consistent trends in tangential velocity, axial velocity, and pressure distribution.As the bottom outlet diameter increases, the split
ratio gradually rises, and this effect becomes more pronounced with larger sand particle sizes. The separation efficiency also improves with
increasing bottom outlet diameter for a given particle size, and separation efficiency increases for all bottom outlet diameters as particle size
grows. The pressure drop decreases as the bottom outlet diameter increases for a given particle size, and the pressure drop diminishes for all
bottom outlet diameters with larger particle sizes.Within the scope of this study, it is evident that, for sand particles of the same size, a 16mm
bottom outlet diameter yields the highest separation efficiency and the lowest pressure drop, indicating superior separation performance.
