Optimal Design of Discharge Electrode Frame in Electrostatic Precipitator

전기집전기 방전극 프레임 최적 설계

In this study, position optimization of insulation rods and suspension rods in discharge electrode frame of electrostatic precipitator(EP) is performed using finite element analysis(FEA). The object of the optimization is to minimize the difference of altitudes in unevenly sagged horizontal structure and to regulate the size of materials within the allowable stress bounds. Uppermost horizontal channel of discharge electrode frame is highly stressed and uniformity of lowest horizontal angle depends on the position of rods. Ten types of frame are analyzed and one recommended model is presented.
