ABSTRACT:
An electrostatic separator intended for separation of liquid phase systems, made up of mixtures of liquids of various electrical permittivity. In particular, the separator is intended for separation of an oil-and-water emulsion. The electrostatic separator contains a vessel, inside which there is suspended a system of electrodes energized from an external voltage source. The electrode system comprises at least one pair of conducting plates (8), which is attached to a supporting frame (7) and electrically connected with the high voltage winding of a feeding transformer (9), which is placed in the supporting frame (7). The supporting frame (7) is preferably a casting of an insulating material. The conducting plates (8) of the electrode system are preferably connected to the winding of the feeding transformer (9) through a capacitive electrical connection.
