气体放电法氧化高浓度亚硫酸盐

Oxidation of High Concentration Sulfites by Gas Discharge

使用气体放电等离子体对较高浓度的亚硫酸钠进行氧化,在不同电压和频率条件下进行了实验,发现在很低的功耗下,取得了很好的氧化效果.使用交直流叠加电源,亚硫酸钠的转化率随着交流电压的升高而升高.在一定的频率范围内,改变频率对亚硫酸钠的转化率影响不大.

The oxidation of sulfite is an important process in flue gas desulfurization by ammonia method. In this experiment, gas discharge was introduced to oxidize higher concentration of sodium sulfite under different voltages and frequencies. The results indicated that gas discharge could enhance the oxidation with a rather low power consumption. By using power of DC superimposed AC, oxidation rate rose with increase of voltage but had nothing to do with frequencies in this experiment.
