Improvement of filtration speed of charge injection type of electrostatic oil filter

This paper deals with the effects of the configurations of electrodes and filter elements on the filtration speed of a charge injection type of electrostatic oil filter, which has been proposed by Yanada et al. It has been demonstrated that the filtration speed can be increased by injecting charges into oils. However, investigation into the effects of the configurations of the electrode and filter element has been limited. In this paper, several types of filter model with different configurations are proposed and their performance is experimentally investigated. A better filter configuration is proposed.

► We make 7 types of charge injection type of electrostatic oil filter.
► Filtration speed is compared among the seven types.
► We propose the best configuration of the filter.
