“…Furthermore, its comprehensive performance is poor. 8 As l further increases, the downward ability of large-size particles is enhanced. The overall collection efficiency showed a trend of first increasing and then decreasing, while its pressure drop loss was further reduced.…”

“…However, the height of the separator is significantly increased compared to the baseline separator. Contrary to their work, Dehdarinejad and Bayareh 8,9 further analyzed the impact of variable pitch guide vanes with different turns on the separator performance. The guide vane starts from the end of the inlet channel, and its length is equal to the length of the vortex finder.…”

Spiral guide vanes are often used to improve the collection efficiency of cyclone separators, but they are closely related to the parameter variables of the guide vanes. To further improve the performance of the equipment, the separator and spiral guide vanes need to be optimized. In this study, the performance characteristics of the flat-roof (FR) and spiral-roof (SR) separators were compared, and then the multiobjective optimization of the guide vanes was carried out. The design relationship between the parameters of the spiral guide vanes (pitch, number of turns, and side wall clearance) was analyzed and the optimal values were determined. computational fluid dynamics (CFD) and response surface modeling (RSM) were used to obtain precise output responses, while precise fitness functions were constructed between design variables and objectives (efficiency and pressure drop). Finally, the optimal structure design was carried out through a genetic algorithm (GA). The results show that, under the same conditions, the SR separator configured with guide vanes can reduce the pressure drop by 7.9% while ensuring the same collection efficiency. At the same time, compared with the FR separator, the optimal structure selected reduces the cutting particle size by 22.9%. This article gives the optimal performance design solution, which can select appropriate structural parameters according to the specific requirements of efficiency and pressure drop. It can provide an effective reference for the subsequent design and application of spiral vanes.

Cyclone separation is an effective method for the treatment of oily wastewater from offshore oil production platforms. There is a lack of research on the impact of dispersion on the separation efficiency of current liquid–liquid separation hydrocyclones. A numerical simulation method was used to study the effect of the oil droplet characteristic parameters on the separation efficiency of a hydrocyclone oil removal device. An analysis of the trajectory of oil droplets revealed the oil removal mechanism of the hydrocyclone oil removal device: under the guidance of tangential velocity, the oil–water mixed fluid in the equipment generates different centrifugal forces due to the density difference, so oil and water adopt different flow paths to flow out. The effects of the particle diameter, velocity, and concentration of the inlet oil droplet on the separation efficiency were investigated. The droplet size had a positive effect on the separation efficiency, the oil concentration had a negative effect on the separation efficiency, and the speed of the oil drop was directly proportional to the separation efficiency within a certain range. These studies improved the basis for the efficient application of hydrocyclone oil removal devices.
