Hydrocyclone is a very simple and cost-effective way to separate inhomogeneous fluid-solid mixtures. It is important to ensure adequate separation efficiency during their operation. Many researchers have worked to identify the factors that influence separation. Geometry has been identified as one of the most important influencing factors. This article summarises the results of this research in order to provide a comprehensive picture of the importance and impact of each geometric element.

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 characteristics and structural parameters (i.e., internal vortex finder diameter and insertion depth) on separation performance. The research results showed that the larger the diameter of the internal vortex finder, the greater the overflow yield and the larger the cut size. The finest internal overflow product can be obtained when the internal vortex finder is 30 mm longer than the external vortex finder. The separation efficiency is highest when the internal vortex finder is 30 mm shorter than the external vortex finder.

“…The pressure difference between the inlet and the vortex finder can be clearly seen in Figure 6. Comparing a)-cyclone to b)-cyclone, it can be seen that a larger pressure difference can be achieved with the feed nozzle used for a)-cyclone than with the nozzle used for a)-cyclone This is related to higher tangential velocities (Rocha et al, 2020).…”

During the operation of the hydrocyclone the cut size diameter is the most important data. This is connected to feed rate, which is closely related to the feed cross section. Preliminary research has revealed that square cross-section is more effective than circular cross-section. The research compared 2 types of feed cross sections at 5 different feed rates. One is a standard rectangular cross-section and the other is a square cross-section that narrows with a baffle plate. Preliminary calculations for cut size diameter have shown that better particle separation at all speeds can be achieved with the baffle plate solution. In both types, the increased velocity created decreased cut size diameter. During the simulation, the baffle plate did not cause any abnormalities in the internal pressure and velocity distributions. The simulation revealed that the particles did not behave as previously calculated.
