OH radicals generated by DC corona discharge for improving the pulsed discharge desulfuration efficiency

Abstract： Positive DC corona discharge is formed with needle-plate electrode configuration, in which the water vapor is ejected though the needle points. The purpose is to increase the numbers of the water-based radicals, ionize the water molecule and improve the desulfuration efficiency of pulsed corona reactor. The water ions were determined by four stages molecular beam mass spectrometer and diagnose the water-based radicals by emission spectrograph. A conclusion on formation of ions and radicals with DC corona discharges can be drawn. 作 者： LI Jie    LI Guo-feng    WU Yan    WANG Ning-hui    HUANG Qiu-nan   作者單位： LI Jie,LI Guo-feng,WU Yan,WANG Ning-hui(Institute of Electrostatics and Special Power, Dalian University of Technology, Dalian 116024, China)
