The concentration distribution of droplets in liquid-liquid hydrocyclones was studied using a phase Doppler particle analyzer. The effect of cone angle and inlet flow flux on the concentration distribution of droplets was determined. The cone angle of the hydrocyclone obviously influenced the maximum droplet concentration, especially that in the cone section. The hydrocyclone with a cone angle of 6°p resented the best separation result. A higher inlet flow rate enhanced the separation of droplets from the water. The concentration profiles at five different axial heights presented a parabola law pattern in the radial direction. The optimized hydrocyclone was applied for the dewatering of vinyl chloride monomer (VCM). The amount of residual water could be greatly reduced.

“…Knowles et al [4] used high-speed movies of anisole droplets moving through a hydrocyclone to determine the velocity of liquid flow. More recently, a number of investigators reported their measurements using Laser Doppler Velocimetry (LDV) [5][6][7]. Kim and Lee [8] showed that the diameter of a vortex finder affected the collection efficiency and pressure drop of cyclones, and proposed an energy-effective cyclone design.…”

“…Up to recent years, worldwide researchers made great progresses on the measurement of hydrocyclone flow field, a summary of these measurements is shown in table 1 [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. But the measurement of the three velocity components inside a hydrocyclone is still limited by the following aspects: a.…”

The separation mechanism of hydrocyclone is elucidated by determining the three velocity components of the flow field. In this study, volumetric 3-component velocimetry measurement system was developed to investigate the three-dimensional three-component flow field inside a 35mm mini-hydrocyclone. Measurement results show the magnitude of maximum tangential, axial, radial velocity component in r-z plane of the cylindrical and cone part is about 4:2:1. The parameter n of tangential velocity in the free vortex area is fitted to be 0.5-0.7, which is a variable along axial direction. Radial velocity is non-axisymmetric, while the other two are quasi-axisymmetric. The asymmetry of the radial velocity is found to be the consequence of the existing downward progression of secondary vortices. In addition, the locus of vertical velocity was constructed in three dimensional and the shortcut flow rate was calculated using three dimensional axial velocity. These knowledge helps the further
