Abstract：As an important gas-solid two-phase separation equipment in industrial production, cyclone separator is
widely used in shipbuilding, petrochemical, coal-fired power, resource development. According to the theory of tur‐
bulent mixing laminar flow separation, regarding the actual physical parameters of particles in dusty air and the
structure size of cyclone dust collector as the variable, the corresponding mathematical model of collecting effi‐
ciency was established, which based on the semi-empirical design method of cyclone dust collector proposed
by classical Leith-Licht theory. According to mathematical model, the optimization objective function was pro‐
posed, which was used to optimize the size of cyclone separator by self code. Finally, combined computational flu‐
id dynamics（CFD）method, the dust removal efficiency of the optimized model was verified. The simulation
results show that the theoretical calculation of the mathematical model is in great agreement with the simulation
results, the error is only 1.41%. This method overcomes some shortcomings such as long period of experimental
verification and poor economy, which also has important engineering application value to the optimum design of
cyclone separator.
