Abstract

We have investigated the potentialities of dielectric barrier discharges (DBD) for aerosol electro-processing with a special focus on ion production and aerosol charging for deposition (filtration and materials) and aerosol measurement tools. The advantages and drawbacks of aerosol injection downstream or upstream of the discharge are compared according to the application. The main parameters that control ion production and transport are investigated based on post-discharge ion current measurements. Post-DBD aerosol chargers are compared for submicron particle size measurements based on aerosol bipolar charging and electrical mobility analysis. Finally, the principle of counterflow extraction of bipolar ion from an atmospheric pressure DBD is established from upstream measurements of positive and negative ion fluxes in air, without neither ozone (<0.1 ppmv) nor nanoparticles.

介质阻挡放电作为气溶胶充电的双极离子源:在过滤、薄膜和气溶胶尺寸测量中的应用

我们研究了介电阻挡放电（DBD）在气溶胶电处理中的潜力，特别关注离子产生和气溶胶充电，用于沉积（过滤和材料）和气溶胶测量工具。根据应用比较了在排放的下游或上游喷射气溶胶的优点和缺点。基于放电后离子电流的测量，研究了控制离子产生和传输的主要参数。基于气溶胶双极充电和电迁移率分析，对DBD后气溶胶充电器的亚微米颗粒尺寸测量进行了比较。最后，从大气压力DBD中逆流提取双极离子的原理是根据空气中正负离子通量的上游测量建立的，既没有臭氧（<；0.1ppmv）也没有纳米颗粒。
