摘要
采用Blumlein脉冲形成网络(BPFN)型窄脉冲高压电源,在线筒式反应器中对甲硫醚进行降解.利用平推流式反应器模型,推导出脉冲电晕降解污染物的动力学方程,并对实验结果进行了曲线拟合.结果表明:甲硫醚的降解符合无明显自由基终止反应模型,甲硫醚的去除量与能量密度成正比,拟合曲线的相关系数大于0.99.初始浓度从510 mg.m-3增大到1 145 mg.m-3,速率常数k1仅从0.824 4升高到0.963 2,对能量利用率提高不大;流量从1 L.min-1增加到1.5 L.min-1时,速率常数k1从0.963 2升高到1.337 5,显著提高了能量利用率.
Dimethyl sulfide（DMS） was decomposed in a line-cylinder reactor by using high voltage power with Blumlein pulse-forming network（BPFN）.The kinetics of DMS decomposition with pulse corona were deduced with plunger flow reactor model.The curve fitting results showed that DMS decomposition accords with no significant radical terminations model and the correlation coefficients are greater than 0.99.The DMS removal amount was in proportion to energy density.When the initial concentration rose from 510 mg·m-3 to 1 145 mg·m-3,the rate constant increased from 0.824 4 to 0.963 2,the energy utilization improved a few.Nevertheless,when the flow rate rose from 1 L·min-1 to 1.5 L·min-1,the rate constant increased from 0.963 2 to 1.337 5,the energy utilization improved significantly.
