Abstract
This paper presents an experimental study on new water treatment by streamer propagation alternated with electrospray generation. We demonstrate the importance of timing control of both an electrospray generation and streamer initiation. Recently, much attention has been given to the water treatment using discharge plasma in a gas-liquid region. In this study, for a further increase in the contact area between water and discharge plasma, both fine water droplets and discharge plasma are formed in the same region. We have already succeeded in alternate expansion of both fine droplets and streamer corona from the same syringe needle electrode. The purpose of this paper is to expose electrosprayed droplets to streamer discharges by timing control of both an electrospray generation and streamer initiation. To this end, both repetitive pulses and an AC voltage are superimposed on a DC voltage applied to a syringe needle electrode. Peak voltage value, frequency, and phase of these superimposed voltages are optimized. It is observed that streamers propagate through a spray region (gas-liquid region), by using a gated image intensifier. In this case, it is shown that persistent substances in water are decomposed. These results suggest that electrosprayed droplets are exposed to streamer discharges and as a result, active species are generated.
