Abstract:To obtain the drift velocity variation regularity of charged particles in a novel transverse plate electrostatic precipitator, the equation of theoretical drift velocity was deduced based on the force analysis of charged particles. The dust removal experiment was conducted by changing factors of applied voltage,mean airflow velocity, electrode and plate distance. The effective drift velocity of charged particles was deduced from dust removal efficiency according to Deutsch formula. The effect of each factor on the effective drift velocity was discussed. The results show that the effective drift velocity of charged particles increases with the increase of applied voltage under normal operating voltage. With the increase of mean airflow velocity as well as electrode and plate distance, the effective drift velocity of charged particles increases first and then decreases. The semi-empirical drift velocity formulas are obtained by fitting theoretical drift velocity with effective drift velocity of charged particles under different conditions.
