Flue Gas Desulfurization Denitrification Technology Using Plasma Induced by Corona Discharge ―DC Power Supply

摘要

DC power supply is one of power supply modes of the plasma desulfurization reactor. The conventional DC power supply and DC power supply for corona discharge are compared each other in this paper. Furthermore,pulse corona principle diagram and DC corona principle diagram are shown. DC power supply can produce current pulse with 10000Hz or so frequency. DC power supply waveform and DC corona pulse waveform are shown. Total flow rate 50～150m~3/h experiment proves that DC power supply can achieve more than 80% desulfurization efficiency at 2Wh/Nm~3 injected power.
