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

• Has been studied experimentally track changes of dust particles oscillate with increasing frequency voltage.
• There have been changes in the position description of individual particles in a cloud of dust in the planar single-phase cylindrical curtain.
• The path of single particle by changing the frequency of the voltage were studied in order to increase the efficiency of electric curtain.

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.
