“…In the same study, using the response surface technique, the author proposed to investigate the influence of four geometric variables on the separation efficiency of filtering cyclone: diameter of the overflow, the diameter of underflow, the height of the conical section and the length of vortex finder. Fukui et al (FUKUI et al, 2011) proposed an adaptation of filtering cyclone which modifies the conventional cyclone. In the study, the authors propose a new equipment which introduced a porous sintered metal cone.…”

The cyclone separator pressure drop depends on the geometry and the operating conditions. Alternative equipment to decrease pressure drop is the filtering device. In this paper, the effect of inlet height, inlet flow rate, and conical section permeability about the filtering cyclone performance (Euler number) is studied through CFD simulations. The experimental and numerical results indicate that the turbulence model Large-Eddy Simulations (LES) reasonably predict the pressure drop in high swirling flows in filtering cyclones. CFD simulations suggest the Euler number increase with the increase of inlet height and decrease with the increase of flow rate and permeability. However, there is an interaction between the permeability with the other two variables. Therefore, this study suggests that CFD models can be used as instruments to evaluate same structural and operational variables in the filtering cyclone performance.

Effects of Sintered‐Metal Cone Length on Gas‐Cyclone Classification Performance

The gas cyclone is a classic flow device commonly used in the separation of particles from a gaseous flow stream. The gas-cyclone classification performance is affected by the length of the porous sintered-metal cone. Three different lengths of porous sintered-metal cones were tested to evaluate the classification performance of a gas cyclone. Clean air was fed into the cyclone through the cone. The cone's particle cut size depended on the amount of clean air injected into the cone. In medium and long cones, a very small amount of injected clean air reduced the particle cut size, whereas in short cones, the cut size remained approximately constant and was greater than that for the traditional acrylic resin cone. In all cases, clean-air injection reduced the powder deposition to values lower than those for acrylic resin cones. The results provide application-based guidelines for the design and usage of sintered-metal cones.
