摘要:
为了在流动的水中产生交流电弧对废水进行处理,设计了实验系统及测试电路,建立了适合水中交流电弧的动态模型。将经典的Mayr和Cassie电弧微分方程模型以串联电阻的方式联合起来,针对水介质的特点引入了最小电导参数,确立了模型参数的求解方法。并将电弧数学模型转化为电路模型,对电弧的动态伏安特性进行了仿真。仿真结果表明:实测与仿真的电弧电压、电流波形基本一致;水中交流电弧放电过程存在气液两相放电,但稳定的电弧放电实质上发生在水蒸气中;稳定燃弧电压为100V, 电流自然过零时存在1~2ms的熄弧时间;熄弧时段内,电流接近于零并且变化缓慢,电压则迅速升至约1500V使电弧重燃。
Abstract:
In order to use AC (Alternate Current) arc discharge in flowing water to process waste-water, the experiment system and measurement circuit were designed. A dynamic model which suited the AC arc in water was established. This model combined Cassie with Mayr arc differential equation models as two resistances in series. Considering the special need of water medium, a parameter of minimum electric conductance was introduced. Furthermore, the solution of the model’s parameters was deduced. The mathematic model was converted to a circuit model and the arc’s dynamic voltagecurrent characteristics were simulated in this conversion. The results demonstrate that the simulated waveforms of arc voltage and current accord with the measurement waveforms in a large extent. There exists gas and liquid two phase discharge during arc generating process but regular arc discharge virtually occurred in vapor. When discharge is regular pattern, arc voltage is about 100V, and the arc have 1~2 ms extinct time when current zero naturally. During this period, the current is about 0 and varies slowly, while the voltage rise to about 1 500 V rapidly, which reignited the arc.
