The invention relates to a technique for separating mixtures of liquids and gas in an electric field and can be used in the preparation of production of oil wells in fields.

The purpose of the invention is to increase the efficiency of the process of separation of the emulsion into oil, gas and water by ensuring that the conditions for the separation of the destroyed water-oil emulsion in the apparatus are separated.

The drawing shows the proposed electric separator.

The electric separator comprises a housing 1 with a nozzle 2 located in the upper part for the removal of gas and a system of vertical corona 3 with needles and precipitating 4 electrodes. The corona electrodes 3 are connected to insulators 5 and are connected through a bushing 6 to a high-voltage current source. Precipitation electrodes 4 and housing 1 are grounded. Under the electrodes 3 and 4 there is a dispenser 7 connected to the raw material collector 8. Under the dispenser 7 a funnel-shaped partition 9 is installed, dividing the housing 1 into two zones. In the lower zone of the housing 1 under the partition 9 (above its lower section), the oil drainage collector 10 is placed, made in the form of a perforated ring pipe and connected to the pipe 11. At the bottom of the housing 1 is installed a water outlet 12.

The separator works as follows.

The gas-water donut to the emulsion enters through the raw material collector 8 and is sprayed in the gas phase with a spray gun 7. When dissolving: 1, there is an intense degassing of the liquid. The evolved gas is discharged through the plug 2, and the liquid droplets, the passage through the electrode system and acquiring an electric charge from the corona electrode 3, are deposited on the precipitation electrode 4 and run down as they accumulate. In this case, the fluid representing

a water-oil emulsion, it is processed in the electric field of the system of electrodes 3 and 4, whereupon the destruction of the emulsion and coarsening occur

with water droplets. Diluted water-oil on the emulsion is collected in the funnel-shaped partition 9 and enters the lower part of the housing 1. By placing the collector 10 above the lower edge of the partition 9, the emulsion moves up

 flow to the reservoir 10. At the same time, the globules of water settle at the bottom of the housing 1 and, as they accumulate, are discharged through the pipe 12, and the dehydrated oil enters the collector 10 and is discharged through the pipe 11.

The presence of a funnel-shaped partition inside the body of the electric separator ensures that the destroyed water-oil emulsion flows down from the electrodes and enters it in the lower part of the settling unit.
