纳秒脉冲电源下电晕放电去除苯乙烯
Styrene removal using corona discharge combined with nanosecond pulse power supply
摘要
Abstract
An efficient and reliable pulsed power generator is developed both in circuit principle and design implementation.Experimental results show that the rising edge of the pulse is 15 ns,pulse width is 30 ns.The maximum peak voltage is 20 kV when the output is connected in series,the maximum peak current after parallel is 340 A.The power supply frequency varies from 50 to 600 Hz and the polarity of the output pulse can be adjusted.At the same output energy,the efficiency of negative pulse is only 37.4％,while positive pulse is 87.3％.When the pulse frequency is 600 Hz,the reactor power is 59.4 W.When the energy density is 27.4 J · L-1,the degradation efficiency of styrene reaches 98.6％.At the same energy density,the removal rate of styrene under negative pulse discharge is higher than positive pulse.关键词
