Abstract
In order to reduce water consumption (especially in remote areas) for the self-cleaning dust removal systems, the efficiency of a three-phase traveling electromagnetics wave for some designed Electrodynamics Dust Shield (EDS) setups are simulated and also experimentally tested. The designed Fresnel rings electrodes EDS system showed about 25% enhancement on light collecting power and a substantial improvement on dust removal efficiency, as well. On the other hand, for the fabricated EDS systems the dust removal efficiency has been tested as a function of the dust particle size, respectively. In this study, the removal dust particles has been sampled from three different Iran's desserts with a vast size ranges, which matches with many of the remote areas in the world. It was confirmed that the sweeping frequency range from 5 to 100 Hz improved the cleaning efficiency and also the sweeping time lasting reduced about half for the zigzag electrode EDS system in comparison to a simple parallel bar one. For designing the different EDS systems, the well-known Finite Element calculation method (COMSOL Multiphysics software) has been employed, respectively.
