The invention relates to devices for breaking a m-type oil-in-field emulsion in an electric field, in particular for dewatering oil-water emulsions in the oil refining industry.

A device comprising three pairs of electrodes is known, each pair of which is periodically subjected to a high voltage of 1J.

However, some of the components: the dll for which this rotational field is not optimal, do not have time to coalesce. The device closest to the technical essence and the achieved result to the proposed device is a device for breaking an emulsion in an electric field, including electrodes, supply and discharge connections 2 J.

The disadvantage of such a device is its low efficiency, due to the fact that the optimum electric field exists only in the area near the electrodes, and with an increase in voltage, breakdown is possible,

The aim of the invention is to increase the efficiency of the process and the safety of the operation of the device.

For this purpose, the device is equipped with a variable cross-section chamber with a constriction in the middle part, made of a non-conducting material and placed between the electrodes, and the discharge connection is located in the narrowed part of the chamber.

The invention is illustrated in the drawing.

The device contains electrodes 1, a chamber 2 with a constriction 3, an outlet nozzle 4 in the middle part and inlet nozzles 5. The walls of the chamber 2 are made of a non-conducting material, -.

The device operates in the following way.

The emulsion enters through the nozzles 5 into the chamber 2 located between the electrodes 1. In this chamber a non-uniform field is created and the final volume of the volume (limited by a part of the chamber) is created with an optimum voltage by selecting sections of the chamber 2 in different parts of the interelectrode space and potential differences electrodes 1 ..

The coalescence of water droplets (t, e, the formation of conductive chains) occurs primarily in the constricted part of the electrode-space (where the current density is maximum), thereby eliminating the short distance between electrodes 1. The deposition rate of water in the proposed device is several times more than in conditions of a uniform or rotating floor.

The use of the proposed device dp destruction of water-oil emulsion provides the possibility of increasing the tension of the field in the interelectrode space when eliminating breakdowns, which increases the efficiency and safety of the process of destruction of emulsions in the electric field, ...
