Description

 The invention relates to devices for separating mixtures of two liquids with different densities, for example, hydrocarbon condensate-water mixtures, and can be used in the oil and gas refining, oil, gas, chemical and petrochemical industries.

 Known apparatus for separating mixtures, containing a housing with inlets for input and output of light and heavy phases and located in it at a distance from each other uneven partitions, one of which is placed at a distance relative to the base (see ed. St. USSR 581968, class B 01 D 19/00, 1975).

 A disadvantage of the known apparatus is that it does not provide high-quality separation of mixtures of two liquids with different densities, because the mixture entering the separation enters the nozzle to exit the light phase.

Common features of the known and proposed solutions are:
- housing with inlets for input and output of light and heavy phases;
- uneven height partitions located in the housing at a distance from each other.

 Closest to the proposed is an apparatus for separating mixtures, containing a housing with nozzles for input and output of light and heavy phases and located in it at a distance from each other uneven partitions, one of which is placed at a distance relative to the base. The upper edge of the high partition is located above the liquid level and is equipped with a plate with a plate with an end bent vertically downward that is inclined towards the high partition and the pipe for outputting the light phase is located on the other side of the vertical axis of the device, opposite the pipe for outputting the heavy phase (see St. USSR 880439, class B 01 D 17/02, 1981).

 The disadvantage of this apparatus is that it also does not provide a sufficiently clear separation of the mixture of two liquids with different densities.

Common features of the known and proposed technical solutions are:
- a housing with nozzles for introducing the mixture and outputting the light and heavy phases;
- uneven height partitions located in the housing at a distance from each other;
- a channel placed in the housing for outputting a heavy phase formed by one of the uneven partitions;
- a plate mounted above the channel.

 The technical problem is to increase the degree of separation of the mixture of two liquids with different densities by preventing ingress into the separated liquid with a lower density of the initial mixture of liquids entering the separation.

 The technical problem is achieved by the fact that in the apparatus for separating the mixture, comprising a housing with a nozzle for introducing the mixture and nozzles for outputting light and heavy phases, a channel for outputting a heavy phase located in the housing is formed of one of the uneven partitions located at a distance from each other and installed above the channel plate, there is a chamber for phase separation, made in the form of interconnected vertical plate and a horizontal plate connected to a partition forming a channel for outputting a heavy phase, and the case, the vertical plate forms a segmented channel with the casing of the apparatus for outputting the light phase, in addition, another of the differently high partitions is placed in the chamber for phase separation at a distance from the horizontal plate, and the mixture inlet pipe is equipped with a liquid flow distributor and is mounted above the camera, a soothing shelf is installed under the mixture inlet pipe, placed above the channel for outputting the light phase and a chamber for separating the phases.

 In addition, the chamber is equipped with shelf separation elements attached to a vertical plate.

 Providing the apparatus with a phase separation chamber made in the form of interconnected vertical plate and horizontal plate connected to the partition forming the channel for outputting the heavy phase, and to the housing, contributes to the qualitative separation of the liquid mixture due to gravitational forces.

 The segmented channel formed between the vertical plate and the casing of the apparatus for outputting the light phase creates a zone of laminar discharge of liquid with a lower density.

 The placement of one of the uneven baffles in the chamber for phase separation at a distance from the horizontal plate forms interconnected vessels and creates the conditions for the heavy phase to rise up the channel formed by the uneven baffles.

 Providing the nozzle of the mixture inlet with a liquid flow distributor creates a directed liquid flow for directing it into the phase separation chamber.

 The supply of the apparatus with a soothing shelf prevents the initial liquid mixture from entering the separated light phase.

 The combination of distinctive features provides the highest quality separation of a mixture of two liquids with different densities.

 The apparatus for separating the mixture is shown in the drawing, where in FIG. 1 shows a sectional apparatus, FIG. 2 is a view along aa, in figure 3 is a view along bb.

 The apparatus comprises a housing 1 with a nozzle 2 for introducing the mixture and nozzles 3 and 4 for outputting the light and heavy phases, respectively. In the housing there are two uneven partitions 5 and 6 located at a distance from each other. One of the partitions 6 forms a channel 7 with the housing 1 for outputting the heavy phase. A plate 8 is installed above the partitions 5 and 6 and the channel 7. A horizontal plate 9 is connected to the partition 6, connected to a vertical plate 10 forming a segment channel 11 for outputting the light phase. The cavity formed by the partition 6, the horizontal plate 9, the vertical plate 10 and the housing 1, is a chamber 12 for phase separation. Another of the different partitions 5 is placed in the chamber 12 for phase separation at a distance from the horizontal plate 9. The mixture inlet pipe 2 is provided with a liquid flow distributor 13 and is installed above the chamber 12. A soothing shelf 14 is installed under the mixture inlet pipe 2, located above the outlet channel 11 light phase and a chamber 12 for phase separation. The chamber 12 is provided with shelf separation elements 15 attached to the vertical plate 10.

 The device operates as follows. The initial mixture enters the housing 1 through the pipe 2 of the input of the mixture and is scattered by the distributor 13 of the liquid flow into the chamber 12 for phase separation. Most of the mixture falls into the stilling shelf 14, from where it flows into the separation zone, the rest of the liquid enters the chamber 12 for phase separation, bypassing the stilling shelf 14. The liquid mixture on the horizontal plate 9 is separated by gravitational forces. The light phase is discharged through the channel 11, from where it is removed through the pipe 3, and the heavy phase accumulates in the lower layers of the chamber 12 and, in accordance with the law of communicating vessels, rises up the channel formed by two uneven partitions 5 and 6, and overflows into the channel 7, from where it is removed through the nozzle 4. In order to avoid the accumulation of gases above the partitions 5 and 6 in the plate 8, a nozzle 16 of the gas outlet is installed above them. The soothing shelf 14 prevents the initial mixture from entering the separated light phase. Shelf separation elements 15 mounted on the partition 10 contribute to a significant increase in the degree of separation of the liquid mixture.
