摘要
为提高放电等离子体技术脱除水中污染物的效率,设计了一种采用负电晕放电方式的水处理装置:待处理水自放电喷嘴电极进入放电反应室,经放电雾化形成小液滴,大大增加了放电等离子体对水中污染物的作用几率.研究了不同喷嘴电极直径和雾化水流量对该处理器电气特性的影响,并对放电等离子体进行了发射光谱的测量.
Water treatment set supplied with negative corona discharge was designed to improve the removal efficiency of contaminants in water by discharge plasma.Water was atomized by injecting into the treatment chamber through discharge nozzle electrode with negative high voltage.The chance increased the reaction happening between the discharge plasma and the contaminants through atomization,since the water forms little drops and water went through the area around the discharge nozzle electrode.The effect of diameter of discharge nozzle electrode and the flow rate of water atomized on the electric characteristics of the set were investigated.Discharge plasma was diagnosed by optical emission spectroscopy.
