A two-dimensional numerical model of the electrostatic precipitator(ESP) is built up

which includes corona electric field

flow field

particle charge and motion field. By adopting the finite element software Comsolmultiphysics

the numerical simulation is carried out. Moreover

on the basis of MINITAB software

full factorial experiments are designed

and the effects of factors such as discharge electrode radius

anode plate spacing

discharge electrode spacing

voltage and particle diameter on performance of the electrostatic precipitator are investigated. The simulation results are in good agreement with the experimental results of the disclosed corona electric field and dust removal efficiency. The first three factors that have the greatest influence on the dust removal efficiency

corona current and power are the voltage V

anode plate spacing W and their interaction effect W×V. Through normality test

the insignificant factors are removed

and an effective response factor regression equation reflecting the performance evaluation index of electrostatic precipitator is constructed

which can predict the dust removal performance of electrostatic precipitator. The research results are of great significance for the design of energy efficient electrostatic precipitators.
