Abstract Pulsed streamer discharge can generates high energy electrons with energy higher than 11.03 eV and enough to excite N2 to its C3Пu state from the ground state, so the density of the high energy electrons can be obtained by diagnosing the relative emission spectrum intensity of the N2(C3Пu→B3Пg) emitted from the pulsed streamer discharge. In the present paper, the density distributions of high energy electrons in the wire-plate DeSO2 reactor with pulsed streamer discharge were studied in air at room temperature and 1 atm, and the influences of pulsed voltage and wire-to-wire spacing on the density distributions of high energy electrons were also studied. The experimental results show that high-energy electrons mainly centralize around the discharge wire of the wire-plate reactor, and the electron density reduces with the increase of the distance from the discharge wire. The pulse voltage has a great influence on the high energy electron density, and the high energy electron density increases linearly with increasing the pulsed voltage. Under a fixed wire-to-plate spacing, when the wire-to-wire spacing is 0.6-1 times the wire-to-plate spacing, the density distributions of the high energy electrons are more uniformity.
