ANALYSIS OF EFFICIENCY AND ENERGY CONSUMPTION OF ELECTROSTATIC PRECIPITATOR BY DIFFERENT ELECTRIC CONTROL METHODS

Electrostatic precipitator(ESP) was mainly divided into two parts: electric control unit and main body. The working principle and technical characteristics of power frequency power supply, high frequency power supply and pulse power supply were described in this paper. The effect rule of the high frequency power supply, pulse power supply and the combination of two kinds of power supply mode for ESP were determined by experimental research, and the corresponding power consumption was analyzed. From the perspective of energy saving, with the premise of meeting the design and final emission requirements, it was better to control the dust concentration of 15~20 mg/m³ in outlet of the ESP. Based on the actual project case, the power consumption of the ESP was reduced through energy saving optimization, and the proportion of energy saving was 30.56%~50.08%. This paper could provide references for the improvement of efficiency improvement and energy conservation of ESP.
