Description

(54) ELECTRODEHEADRATOR

one

The invention relates to devices for the dewatering of oil and other emulsions such as water in oil, in an electric field, and can be used for dewatering oil in fields, refineries and petrochemical plants.

A device is known in the form of a housing with a screw placed inside, in which the emulsion being processed is exposed to a magnetic electric field .ij.

The disadvantage of this device is that the emulsion with enlarged drops of water is removed from the apparatus and its sludge is produced under the action of gravity in the sumps, which reduces the productivity and increases the intensity of the equipment needed to carry out the process.

A known dehydrator, comprising a high-potential electrode located along its axis, a spiral insert, a sump, a water collector tray, and a housing with a body through the input and output slit-like channels, tangential inlet and output nozzles 2.

The disadvantage of this electric dehydrator is that water droplets that are injected from the stream of the treated emulsion I get into the cavity, where their further sludge occurs spontaneously under the action of gravity. This can lead to excessive accumulation of the emulsion in the settling cavity, and not sufficiently large drops of water from the emulsion 10 seconds from the emulsion in the lower part of the apparatus enter the stream of purified liquid that is removed from the apparatus, which worsens the results of electro-emulsion.

15

The aim of the invention is to intensify the process of electric dehydration and water separation by creating a forced circulation in the SOCKET chamber.

20

This goal is achieved by the fact that the electric dehydrator is provided located above one of the slit-like channels, at a distance from the side surface, with a shaped deflector forming a slit-like diffuser with the inner wall of the housing.

FIG. 1 shows a general view of an electric dehydrator; in fig. 2 is a view along arrow A of FIG. 1 in FIG. 3 30 section bb of fig. 1 (arrows indicate the direction of fluid motion in the electric dehydrator and in the sump of the catchment basin), the Electrodehydrator from the cylinder body 1, the high-potential-south electrode 2, and the spiral from the structural material that creates a spiral channel in the body. The housing is equipped with a tangent ripHBapeHHi-jff.tM pipe nozzles 4 and 5 for the entrance and exit of the processed 11KDKTii. The welding angle of the nozzles and the direction of the helix should be matched between, by itself.

The electrical field in the i.iaTo, D electrodes (.; (It is celebrated in) The target space is melted internally by the surface of the housing 1 and the outer surface of the elevator. the fact that the internal cavity of the electrohydrator has a spiral insert 3, the emulsion in the electric field moves 1C to output 5 of the electrolyte dehydrator along the spiral channel, while the droplets of the emulsion of the emulsion simultaneously centrifugal forces. Under the influence of the electric field, the droplets are pushed by the centrifugal forces to the inner walls of the hull and through the slits of the slit-like windows emerge into noa additional water-supply gonn. the water collector with an electric dehydrator housing, with a deflector located above the first one along the emulsion. Thanks to the presence of the deflector from the first window along the emulsion, leakage occurs into the liquid emulsion flow from the pallet, and through the second window separating Shies drops of water come into the pan. Thus, in the pallet there is a circulation of fluid, which accelerates the movement of water droplets to the oil-water interface in the lower part of the pallet and removes oil with insufficiently enlarged drops of water from the pallet into the total flow of the emulsion being processed. The direction of flow is shown in FIG. 2 and 3. The water accumulating in the sump is discharged through the drainage pipe 10. Dehydrated oil is discharged through the outlet pipe 5. When processing low-stable emulsions, the proposed apparatus can be used as a water separator without using an electric field.
