Description

The invention relates to devices for the separation of liquids of different densities and can be used in oil fields to separate the water-oil emulsion.

The purpose of the invention is to increase the efficiency of separation of liquids of different densities by intensifying the process of mechanical action on the intermediate layer.

Figure 1 shows the device, a general view; figure 2 - node I in FIG.

The device contains a process tank 1 with an input distributor made in the horizontal pipe 2 type. The perforations are made in the lower part of the horizontal pipe 2 in a pipe section located below the horizontal plane passing through the pipe axis at an angle of 45. Parallel to the horizontal pipe 1 on the perforation side an inclined plate 3 is installed, the lower edge of which is located above the perforation, while the plate 3 is installed with a gap to the wall of the container 1 and the horizontal pipe 2.

The container 1 is provided with nozzles for discharging a light liquid 4, an output of a heavy liquid 5 and a single coolant: am 6.

The device works as follows.

A mixture of liquids of various densities, for example, water-oil on an emulsion, comes into a technological tank through a horizontal pipe 2 located above the intermediate layer consisting of a highly concentrated emulsion and mechanical impurities. Since the perforation on the horizontal

in the lower part at an angle of not more than 45 ° to the horizontal - PLANE, passing through the axis of the pipe, the outgoing trickles get moving 5 out towards the inclined plate 2.

In the zone of the intermediate layer, the jets create an uninterrupted mechanical action that contributes to the destruction, removal and removal of the separated

10 water and particles of mechanical impurities into the water zone of the tank 1.

The oil separated from the emulsion and the incomplete emulsion of the intermediate layer are lifted upwards and under the terminal plate 3 they move towards the st.enok of tank I. By the gap formed by the plate 3 and the drain of the tank 1., The oil rises into the oil zone, 5

, 20 along the inclined plate 3 goes down and returns to the horizontal pipe 2. From the lower edge of the plate 3, by a gap formed from the horizontal pipe 2, is not destroyed

, 25, the emulsifier is lowered downwards and picked up by the streams coming out of the openings of the horizontal pipe 2. Thus, multiple circulation of intact fl uxion is ensured.

30 around the inclined plate 3 to the second-fold mechanical impact: t, sie on it.

Remove mechanical impurities in the water zone through the nozzle 6 of the sludge outlet, and water through the nozzle 5 of the heavy liquid. Oil is discharged from tank I through pipe 4 of the light fluid outlet 40 g.
