inpact of cyclone size on throughput

A CFD study of the effect of cyclone size on its performance .Oct 15, 2010 . Cyclones of different sizes, were used which named as cyclones I, II, and III. Cyclone I was considered as the biggest and cyclone III was considered as the smallest cyclone. The effects of cyclone size and inlet velocity on hydrodynamics behavior and performance parameters including cut-off diameter and.Effects of cone dimension on cyclone performance - ScienceDirectThe effects of cone dimension on cyclone performance characteristics were investigated in this study. Collection efficiencies for three cyclones with different cone bottom diameters were measured as a function of particle size and flow rate. The measurement results suggest that flow rate strongly influenced the efficiency.

The apex size also has an effect on separation but the effect is minor unless the apex is too small and becomes a physical constraint, forcing material into the overflow. Cyclone retention time is also a minor factor influencing cyclone performance. Within limits, increased retention time would help achieve a finer separation;.

Simulation of mass-loading effects in gas–solid cyclone separators

Mar 10, 2006 . Three-dimensional, time-dependent Eulerian–Lagrangian simulations of the turbulent gas–solid flow in a cyclone separator have been performed. . These two effects have significant consequences for the way the particles of different sizes get . definite effect on cyclone performance and in particular its.

inpact of cyclone size on throughput,Cyclonic separation - Wikipedia

A cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. When removing particulate matter from liquids, a hydrocyclone is used; while from gas, a gas cyclone is used. Rotational effects and gravity are used to separate mixtures of solids.
