“…As potentialities of plane-to-plane ac DBD with long transit time for charging and electro-collection of particles are established (cf 4.1, [126,174,194,195,259]), they can be used for the collection of the aerosol formed in ac APF-DBD for VOC treatment. Besides, in plane-to-plane and packed-beds ac APF-DBD, collected soot can be treated by association plasmacatalysis [202,206,172,[253][254][255].…”

This review addresses the production of nano-particles and the processing of particles injected in atmospheric pressure electrical discharges (APED). The mechanisms of formation and the evolution of particles suspended in gases are first presented, with numerical and experimental facilities. Different APED and related properties are then introduced for dc corona, streamer and spark filamentary discharges (FD), as well as for ac filamentary and homogeneous dielectric barrier discharges (DBD). Two mechanisms of particle production are depicted in APED: when FD interact with the surface of electrodes or dielectrics and when filamentary and homogeneous DBD induce reactions with gaseous precursors in volume. In both cases, condensable gaseous species are produced, leading to nano-sized particles by physical and chemical routes of nucleation. The evolution of the so-formed nano-particles, i.e. the growth by coagulation/condensation, the charging and the collection are detailed for each APED, with respect to fine powders production and thin films deposition. Finally, when particles are injected in APED, they undergo interfacial processes. Non-thermal plasmas charge particles for electro-collection and trigger heterogeneous chemical reactions for organic and inorganic films deposition. Heat exchanges in thermal plasmas enable powder purification, shaping, melting for hard coatings and fine powders production by reactive evaporation.

“…The first study on the particle charge neutralization using a DBD charger was carried out by Kwon, Sakurai, Seto, and Kim (2006). Kawada et al (1999) and Kuroda et al (2003) attempted to decontaminate fine carbon particles and NO x by using a two-stage electrostatic precipitator (ESP), where the typical wire-to-plate charging section was replaced by a DBD charger. Although it is known that fine particulates smaller than 10 m and gaseous pollutants can be controlled effectively with the barrier discharge type ESP, these are very few published results for the collection of submicron particles.…”

“…Because of its high electron density and energy, the DBD in air has been used to clean hazardous air pollutants [16][17][18]. For instance, DBD precharger has been used in the two-stage ESP, which consists of separate precharger and collection electrode sections [19][20][21]. Barrier discharge type ESP has been shown to be efficient for the simultaneous removal of particles and NOx from air [22,23].…”

The aim of the present work has been to quantify the efficiency of Dielectric Barrier Discharges (DBDs) for the collection of submicron particles. The experiments were performed with incense smoke particles having a mean size of about 0.3 µm. An aerosol spectrometer was employed for characterizing the size distribution of these particles at the outlet of Wire-to-Cylinder (WC) and Plate-to-Plate (PP) DBD reactors. The collection efficiency was estimated for various applied voltages (6 -26 kV, 1 -2000 Hz), and airflow rates of 1.6 -24 L/min. The discharge mode was diffuse, in the case of the axisymmetric configuration, and filamentary, in the case of the planar configuration. When flow rate increases, the discharge current and the electric power decrease in both cases. This effect is less pronounced with the planar configuration. Results obtained with the aerosol spectrometer show that the particle collection efficiency of both reactors is higher at high applied voltage and low flow rate; it decreases at high frequency because of particle oscillations, and at low frequency due to the intermittent nature of the discharge. The frequency range for which the collection efficiency is higher than 90% is wider in the case of WC reactor.
