Studies On The Electric Field Characteristic Of Tri-electrode Electrostatic Precipitators By Finite Element Method

Tri-electrode electrostatic precipitators by setting a very equipotential with the discharge of the auxiliary electrodes will be divided into series of alternating electric field layout of the "Charge Area" and "Collecting area" to improve the ESP for high resistivity and fine particles of dust collection efficiency. Electric field characteristics of the impact of Tri-electrode electrostatic precipitators electrode configuration parameters from spacing between collecting electrodes, distance between neighboring discharge electrodes and distance between the auxiliary and discharge electrodes.Study of ESP electric field characteristics of the two methods are experimental and numerical calculation.Experiment can be measured plate current density, numerical calculation can be obtained electric field distribution throughout the space, whichever is more useful to understand the combination of the electric field characteristics of ESP. In this paper, analytical solution of cylindrical electrodes and compared the numerical solution to verify the finite element method for solving the reliability of the electric field ESP. Finite element method to calculate the Tri-electrode electrostatic precipitators control most of the electric field distribution, The law of the corona largest field, electric field strength which is dependent on spacing between collecting electrodes, distance between neighboring discharge electrodes and distance between the auxiliary and discharge electrodes.By numerical calculation and experimental results of combining the use of the current density distribution, collecting electric field strength distribution and the ratio of "Collecting area" and "Charge Area" as a Tri-electrode electrostatic precipitators control most electric performance of the quality of evaluation.Draw Tri-electrode electrostatic precipitators better performance when the electric field configuration of the electrode to adjust the scope and parameters of the form: spacing between collecting electrodes 300≤A 350mm, distance between the auxiliary and discharge electrodes 135mm≤C≤ 165mm.
