Electric Field Distribution of New Polar Matching System in Wet ESP

In order to improve collecting efficiency of wet electsostatic precipitation a new polar matching system is presented. Based on Gauss Theorem and image charge method the mathematical model is established for calculating electric field intensity distribution of the new polar matching system. The results show that the electric field intensity gets homogeneous at the polar plate when polar space is at suitable value. The electric field intensity of the new polar matching system meets Gauss Theorem well at arbitrary section. The structural characteristics of electric polar is affected by many factors, such as: geometrical parameters, dust concentration distribution and applied voltage. The new polar matching system has the advantage of even electric field intensity when the electric polars and discharge nozzle-electrodes are on small distance. The calculated results accord with the actual distribution law of electrostatic precipitator. It can be directly used for the design of wet electrostatic precipitator.
