Research on the Prediction Model of Separation Efficiency of Cyclone Separators
Cyclone separator is a commonly used gas-solid separation equipment in the chemical industry,and separation efficiency is a key parameter in its design and operation.This study constructs a multi parameter model to characterize separation efficiency and analyze the key factors affecting separation efficiency.Simultaneously establish a numerical calculation model and obtain simulated separation efficiency values through simulation.In addition,a cyclone separator test device is constructed to obtain separation efficiency test values through real experiments,and to calculate the relative error of the predicted model results.The results show that the separation efficiency is significantly affected by gas velocity,powder particle size,particle density,separation radius,and flue gas viscosity.There is a positive correlation with the inlet gas velocity,powder particle size,and particle density;Negative correlation with separation radius and smoke viscosity.The results show that the separation efficiency value obtained by the prediction model is 90.278%.The separation efficiency value obtained from the validation experiment is 82.90%,with a relative error of approximately 8.90%.This prediction model can be basically used for calculating the separation efficiency of cyclone separators.The above research provides a new method for calculating the separation efficiency of cyclone separators,and also provides a theoretical basis for optimizing the design of cyclone separators.
