臭氧发生器最佳放电间隙的确定及研究

Determination of optimized discharging gap for ozonizer

利用Q-V李萨如图研究了臭氧发生器的等效电容特性,同时测量了不同电压、放电间隙下的注入功率,同样气隙下随着外加电压的增大,注入功率加大;而给定电压,增加气隙距离时,注入功率先增大后减小,存在一个最大值点;最大值点的位置随着外加电压的增高,向气隙距离增大方向偏移。以Manley功率公式为基础,理论上推导了注入功率随气隙距离的变化特性,与实验结果类似。随着注入功率的增大,臭氧产量也逐渐增大,不同电压、气隙距离下获得的臭氧产量曲线与功率曲线呈现相似的变化特性。臭氧产量越高,臭氧产率就越小,是一对不可调和的矛盾。

The equivalent capacitor of the ozonizer was studied by Q-V Lissajous figure. The inject power was measured under various voltage and discharge gaps with the Q-V Lissajous figure. The injection power increases with the increasing voltage under the same gas gap. But under the fixed voltage, the injection power first increases then decreases with the increasing gas gap. There is a max power point on the power versus gas gap curve. And this point moves toward the gap increasing direction when voltage increases. The power features versus gas gap were also derived from the Manley power formulation, showing similar regularity with the measured results. The ozone productivity increases with the increasing power. And the ozone production curve under various voltage and discharge gaps shows similar trend with the power curve. The ozone yield decreases with the increasing ozone production.
