Characteristic of porous discharge electrode connected with the ground in atomization corona discharging
An electrode structure possessing porous arrays has been put forward to atomize water and induce corona discharges.Therefore,based on the experimental researches of the status of corona discharge and V-I characteristics,atomization conditions,the impact ofwater supply and the purification effect have been studied.The results show that the porous discharging electrode with water supply is of excellent electro-hydro-dynamic (EHD) atomization characteristics and can attain better atomization status.Based on the V-Icharacteristics from the orthogonal experiments between porous electrode length and space,corona discharging process has been attained under the conditions of 10mm electrode length and 40mm electrode space.Furthermore,by means of controlling the velocity of water supply,the two processes of corona discharge and water atomization can exist stably and synchronously.In addition,the charged droplets with high speed via porous electrode water-atomization and corona discharge spray to the collecting electrode and form an even water film and the washing effect of it to the electrode is quite effective.It needs to be emphasized that the adoption of electrode system with water supply connected with the ground can carry out the water atomization corona discharge feasible to capturing particulate matters (PM).
