Abstract：Based on computational fluid dynamics and FLUENT module of ANSYS software platform, the effects of flue gas and dust characteristics on the dust removal efficiency of converter electrostatic precipitator was simulated in this paper. From the results, the faster flow rate, the lower dust removal efficiency will be, and the higher humidity and concentration, the higher dust removal efficiency will be. With the increasing of solid particles density and size, the dust removal efficiency will decrease. According to above law, the L16(45) orthogonal simulation were designed and the results indicated that the influence degree of the electrostatic precipitator dust removal efficiency from high to low is particle diameter, velocity, dust true density, dust concentration and gas humidity. Under the conditions of discharge voltage 35 kV, the best dust removal effect conditions were that velocity of flue gas was 0.5 m/s, dust particle diameter was 40 ?m, flue gas dust concentration was 40 g/m3, flue gas humidity was 25%, true density of dust was 4000 kg/m3. In this case, the dust removal efficiency will reach 99.9%.
