Description

The invention relates to devices ‘for processing oil products, oil and other organic liquids in an electric field and can be used in the oil refining and petrochemical industries.

The closest to the proposed technical essence and the achieved result is an electric separator, including a housing with liquid inlet and outlet nozzles, and a liquid distributor over which electrodes are installed [1].

A disadvantage of the known device is that high-quality purification of petroleum products in it is achieved only at sufficiently high initial concentrations of electrolyte. In addition, the processing quality is negatively affected by the uneven distribution of the product over the cross section of the Apparatus, especially in large

The purpose of the invention is to improve the quality of the liquid.

For this purpose, the electric separator is equipped with a perforated partition installed above the distributor, and a reagent supply pipe located above the partition.

In addition, the electric separator is equipped with mixing vertical pipes installed at a distance from the partition opposite the holes, chippers placed at a distance from the ends of the pipes, and an overflow plate mounted on the partition.

In FIG. 1. Schematically depicts an electrical separator, a General view in section; in FIG. 2 - node I in FIG. one.

The electric separator contains a housing 1. inside of which are grounded 2 and potential 3 electrodes. The latter are fixed in the lattice 4, suspended on insulators 5 and soya diaparats.

connected with a current-carrying cable through a bushing insulator 7 with a rectifier 8. A liquid outlet pipe 9 is placed in the upper part of the electrical divider, and a liquid inlet pipe in the form of a perforated mother liquor 10 from the pipes is located in the lower part:

A perforated baffle 11, a vertical baffle 12 and an overflow plate 13 are horizontally placed under the bottom electrode. Vertical pipes 14 are mounted above the bore holes of the baffle 14, which are secured to the baffle 11 with a gap and are closed on top with chippers 15 installed with a gap to the end of the pipe ·, ka. A reagent supply pipe 16 is installed above the partition 11; there are pipes 17 and 18 in the bottom.

The electrical separator operates as follows.

The oil product is fed into the apparatus through the openings of the mother liquor 10, over which a layer of reagent electrolyte is supported. After processing, the oil passes through the holes of the perforated partition 11. Fresh reagent is supplied to this partition through the nozzle 16. The level of the reagent is maintained higher than the chippers 15 by means of an overflow plate 13. The density of the oil is lower than the density of the reagent, therefore, the reagent circulation is established inside the nozzles 14, accompanied by dispersion in the oil product. The flow direction is shown in FIG. 2 arrows.

An oil product with reagent-electrolyte particles dispersed in it is sent to the interelectrode space, where in the electric field the velocity of these particles relative to the non-polar oil product flow is quite high and the treatment is most effective. Due to the interaction of the reagent particles with each other, they merge into larger ones and settle on the baffle 11. The processed and refined oil product is discharged through the pipe 9. The reagent flows from the baffle to the bottom of the apparatus, interacts with the jets of oil flowing through

722554 4 versts of the mother liquor, and after settling down from the oil product droplets dispersed in it, it is discharged through the pipe 17.

Part of the reagent is sent for regeneration, neutralization or disinfection, and part is injected into the processed oil product using pumps or an ejector before it is fed to the apparatus.

Thus, the proposed device provides a multi-stage countercurrent interaction of the processed liquid with the reagent sequentially in the mixer and piping 15 to the device, at the outlet of the mother liquor, in the mixing elements on a horizontal partition, and, finally, in an electric field, where the reagent particles carried away by the flow they intensively move relative to the flow, merge with each other and settle on the perforated partition.
