The device is a horizontal tank 1 with fittings for the input of emulsion 2, oil outlet 3 and waste water 4.

Inside the tank 1 are mounted transverse 5 and vertical 6 partitions. Between partitions 5 and 6 along the walls of the container 1, jumpers 7 are mounted that do not reach to the bottom of container 1, which are angled to each other and diverge in the direction of fluid flow in the apparatus. Jumpers 7 are provided with inclined shelves 8 adjacent to the wall of the container 1 and jumper 7. In this case, the shelves 8 are inclined downward to the side walls of the apparatus. No holes 9 are provided to the lower edge of the bridges 7 for the emulsion to flow. The cross-sectional areas of these openings are reduced along the flow, creating conditions for a uniform distribution of the emulsion over the interface. The holes 10 in the inclined shelves 8 are designed for the outflow of free excretion of water.

The device works as follows.

The high-watered emulsion through the nozzle 2 enters the distribution chamber, and then into the channels formed by the walls of the tank 1, the bridges 7, the inclined shelves 8 and the vertical partition 6. In the chamber and canals it is divided into free water and partially dehydrated emulsion ( oil) The emulsion through the holes 9 in the jumpers 7 enters the phase separation zone of the working chamber formed by the jumpers 7 and the inclined shelves 8, partitions 5 and 6. The shelves 8, made inclined, do not silt, and the holes 10 provide the outflow of water iys at break emulsions in the distribution chamber. The discharge of free water from the distribution chamber is carried out as follows. The main flow of water moves under the partition 5, connected to jets flowing out through the openings 10 in the shelves 8. Then the water flows under the lower edge of the vertical partition 6 and then through the shtutser 4 together with the water separated in the working chamber . Separate oil over the partition 6 through the nozzle 3 is removed from the apparatus.

The use of the invention improves the reliability of the apparatus by narrowing the channels in the distribution chamber and reducing the cross-sectional area of the holes for emulsion flow downstream.

Q flow, which contributes to an increase in the hydraulic resistance through the channel (the pressure in the holes increases) and thereby a gradual increase in the rate of emulsion flow from them from the hole to the hole. All this (taking into account that the interfacial surface in the working chamber has the shape of a trapezium) ensures uniform distribution of the emulsion over this surface.

By ensuring the operability of the apparatus at any position of the phase separation level, as when the level of the phase boundary changes, the emulsion that enters the distribution chamber is then uniformly introduced along the entire length of the working chamber through the holes in the bridges or into the layer

5 (with an increase in the level of the interface), or into the emulsion (with a decrease in the level), the metal intensity of the apparatus decreases, since it excludes pressureless distributors, which overlap the working chamber. In addition, the proposed design

0 apparatus allows to increase its useful volume. The device becomes more convenient for technical inspection and maintenance.
