The Effect of Different Configurations of Collecting Electrodes on the Flow Visualization inside a Wire-Plate Electrostatic Precipitator (ESP) in the Vicinity of the Collecting Electrodes

摘要

In ESPs, collection efficiency for fine particles is significantly affected by the electric field and gas flow conditions. The purpose of this research is to visualize gas flow trajectory in the vicinity of the collecting electrode according to two different configurations of collecting electrodes. Results showed an obvious difference between the gas flow trajectory in the two ESPs, and this affects the collection efficiency of the ESP. Also it shows that the gas flow trajectory can be controlled by changing the surface properties of the collecting electrodes in the ESP.
