Abstract

The invention relates to devices for the primary treatment of oil, its dehydration and desalting, and can be used in oil fields for the preliminary separation of water and salts from oil. The aim of the invention is to increase the efficiency of oil demulsification, reduce energy consumption and increase safety. The device includes a pipeline section, piezoceramic elements, mesh electrodes installed between the piezoceramic elements and electrically connected with their metallized electrodes, a cylindrical dielectric pad and a vibrator acoustically connected with the piezoceramic elements. Water-oil on the emulsion, entering the interelectrode space formed by the grid electrodes, is subjected to repeated exposure to an alternating electric field created by piezoceramic elements under the influence of mechanical vibrations and acoustic fields on them. 1 il.
