等离子体功率分配方式对异戊烷降解效果的影响研究

Study on the Effect of Plasma Power Distribution on Isopentane Degradation

在等离子体治理有机废气工业应用中,功率的分配是基于等离子体电源的输入功率,而实验室考察有机废气治理效率是基于等离子体实际的放电功率。通过探究等离子体电源输入功率与实际放电功率的关系,总结放电过程中能量的损耗规律,并考察不同功率分配方式下,异戊烷去除效率的变化规律。结果表明:电源输入功率小于实际消耗总功率,大于等离子体反应器实际放电功率;电源能量损耗随总输入功率的增大而升高;放电功率占输入功率的比值随总输入功率的增大,由40%提高至90%。当多个等离子体反应器串联,总放电功率一定时,增加进气端反应器放电功率的分配比例可提升异戊烷去除效率。

In the industrial application of plasma treatment with organic waste gas,the power distribution is based on the input power of the plasma power supply,and the laboratory investigation of organic waste gas treatment efficiency is based on the actual discharge power.By exploring the relationship between input power and actual discharge power,the law of energy loss during the discharge process was explored,and the variation rule of isopentane removal efficiency based on different power distribution methods was investigated.The results showed that the input power was less than the actual total power consumed but greater than the actual discharge power of plasma reactor.The energy loss of power supply enhanced with the increase of total input power.The ratio of discharge power to input power elevated from 40%to 90%with the increase of total input power.When multiple plasma reactors were connected in series and the total discharge power was constant,the removal efficiency of isopentane could be improved by increasing the discharge power distribution ratio of the inlet reactor.
