Novel conical section design for ultra-fine particles classification by a hydrocyclone

J. Ye, Y. Xu, X. Song, and J. Yu, “Novel conical section design for ultra-fine particles classification by a hydrocyclone,” Chemical Engineering Research and Design, vol. 144, pp. 135–149, Apr. 2019, doi: 10.1016/j.cherd.2019.02.006.

Abstract To overcome the limitation of the conventional hydrocyclone for the ultra-fine particles classification, the novel conical section design of the hydrocyclone is computationally investigated in this work. The electrolytic manganese dioxide (EMD, MnO2) powder, whose size is in the range from 0.2 μm to 70 μm, is took as a study case, and the feed solid concentration (SC) is up to 20%wt. The conical section with the modified cone design is proposed to enhance the performance of hydrocyclones. In addition, all the hydrocyclones are equipped with an arc inlet to obtain the pre-classification effect. The micron particles classification with the demarcation at 5 μm is accomplished in the novel hydrocyclone as the classification sharpness (Ss) is improved from 0.833 to 0.938 at the feed solid concentration of 5% wt. The combination of moderate conical length and modified cone with wide radial space near spigot is the outline of the high classification sharpness hydrocyclone. The dynamics analysis illustrates that the classification performance is attributed to the comprehensive effects of force, residence time, and separation space.

Notes:

Highest separation sharpness can be achieved by creating a balance between long cone section (high separation efficiency, fine particle in underflow) & short cone section (loss of coarse product in overflow).
Medium-length cone with moderately large radial space gives high level force field and sufficient separation space.
Wider cone design achieves improvement of classification sharpness at the cost of coarse product loss.
The effect of drag force is more significant on coarse particles
