Multi-objective optimization of a novel vortex finder for …

This study proposed a multi-objective optimization of novel vortex finder, called Slotted Vortex Finder (SVF), applied in the Stairmand cyclone separator, to obtain a most appropriate geometric configuration for performance improvement as the Stairmand cyclone separator had been widely used in industry for dust removal since last century.

Design of a novel gas cyclone vortex finder using the adjoint method

The vortex finder is an essential part in gas cyclones where the shape and diameter highly affect the cyclone performance. Many optimization studies have been conducted to optimize the cylindrical vortex finder diameter. This study introduces a new vortex finder shape optimized for minimum pressure drop using the discrete adjoint method.

Oil-water separation in a cylindrical cyclone with vortex finder

The vortex structure in the cores of cylinders with different inlet velocities is given in Fig. 10. The axial velocity in the main cylinder is limited to 0–10 m/s to clearly distinguish the shape of the vortex core. The results show that the inlet velocity has little influence on the equivalent length of the vortex core, which is 547 mm, 534 ...

The effect of vortex finder diameter [4], the cyclone inlet dimensions [5], the cyclone height [6], and the cone-tip diameter [7] on the performance has been investigated showing that the most ...

Vortex finder for cyclone separator

A vortex finder for a cyclone separator, comprising a plurality of superposed rings each including a plurality of suspended plate segments. Each of the plate segments includes a main plate having radially offset upper and lower end portions, opposite inner and outer faces, an upper support member integrally formed with the upper end portion to protrude from the outer face, and a …

Vortex finder optimum length in hydrocyclone separation

Nonetheless, if the vortex finder tip reaches the conical zone, some coarse particles might reach the return overflow stream instead of exiting through the apex and this causes a decrease in efficiency. Optimum length depends on feed particle size and distribution and this should be determined preferably by experimentation.

Influence of Vortex Finder Structure on Separation Performance …

In view of the difficulty of traditional hydrocyclones to meet the requirements of fine classification, a double-overflow three-product (internal overflow, external overflow and underflow) hydrocyclone was designed in this study. Numerical simulation and experimental research methods were used to investigate the effects of double-overflow flow field …
