Confinement of charged dust particles by a hybrid-type electric curtain

2012

Abstract The hybrid-type electric curtain (HTEC) comprises a planar electric curtain and a perpendicular planar condenser. Serial cylindrical electrodes are supplied with AC voltage, whereas the condenser is fed with DC voltage. HTEC allows for better control of the particle position shift in space. The particle oscillation path within the hybrid curtain has been photographically analysed. The changing particle path was recorded according to a DC changing voltage value and a constant AC voltage value. The aim of the paper is to describe a successful method that enables one to experimentally determine the region where the particle can be stably oscillated.

Electrodynamics of charged dust particles and repulsion force within plane-type electric curtain

2001

Abstract The electrodynamic behaviour of dust particles in the plane-type electric curtain with a standing wave is investigated. The way a trajectory of oscillation of a single dust particle varies as a result of changes in the electrical supply voltage is analysed. The electric curtain is proposed as a generator of charged dust particles.

Influence of the AC voltage frequency on the oscillation trajectory and path length of particles inside a planar–type electric curtain

2015

Abstract Experimental investigations of the average path length of oscillating dust particles inside a planar –type electric curtain (PTEC) are presented as a function of the frequency of the AC voltage. The frequency was adjusted within the range of 10–300 Hz. The oscillation paths of feldspar particles of diameter 40–60 μm inside a small cloud were recorded photographically. The main purpose of this investigation was to study the changes in average path length as a function of the supply voltage frequency. These results can be used to improve the precipitation and separation processes for charged dust particles inside a PTEC.
