ELECTRIC CLEANER OF DIELECTRIC LIQUIDS Russian patent published in 2000 - IPC

FIELD: cleaning of dielectric liquids from mechanical impurities. SUBSTANCE: electrodes of same sign of potential, for instance, negative potential, are electrically connected to body of cleaner and electrodes of opposite sign of potential are placed with clearance relative to internal wall of body and together they form additional pairs of electrodes-precipitators arranged over perimeter of cleaner. Last precipitating electrode in flow of liquid has sign of potential opposite to sign of potential on body. It makes it feasible to prevent movement of filtrate from bottom part of body of cleaner to outlet from it. EFFECT: improved efficiency of cleaner. 2 dwg
