The invention relates to an oil dewatering device and can be applied in fields. A pipe sump is known, including a horizontal pipeline divided by inter-seals with openings into sections, in each of which a pipe O fixed in the partition is placed. However, the known device is characterized by the difficulty of adjusting the water-oil phase separation level in each section due to the small volume of the aqueous phase. The closest to the proposed technical essence and the achieved result is a pipe sump, including a horizontal pipeline, divided vertically by fw partitions with openings into sections, each of which has oil and water outlets, and the first through the flow section bottom of pipeline 2. The disadvantage of this device is the possibility of accumulation of a stable intermediate layer and mechanical impurities in the settling zone during the operation of the pipe sump with He part broken; The effect is in the adhesive joint interaction of the drops of an intact emulsion with the surface of the inner tube and the walls of the pipeline. At the same time, the depth of dehydration of oil can significantly worsen. The purpose of the invention is to displace the depth of dehydration of oil by more fully withdrawing a standing intermediate layer and mechanical impurities from the settling zone and more fully utilizing the useful volume of the settling zone. The goal is {, achieved by the fact that in a pipe sump, including a horizontal pipeline, divided by vertical partitions with a hole in a g and into sections, each of which has oil and water outlets, and the first sections have a downstream channel in the downstream section, Each of the first sections along the flow is provided with a horizontal partition, attached with one end to the vertical partition above the hole, and a vertical plastic layer attached to the free end of each horizontal overflow and upward. FIG. 1 schematically shows a pipe sump; in fig. 2 - section of dehydration.: By moving it from left to right; in fig. 3 - section A-A in FIG. 2. Pipe sump with: hold horizontal pipeline 1 bol:; th diameter, divided into sections by vertical partitions 2 with openings 3. In partition 2 fixed at one end of the horizontal horizontally a partition 4 forming a duct wall 5 in the lower part of the duct for transferring the emulsion from one dewatering section to another. At the free end of the partition 4 is attached transverse plate b, directed vertically upwards. In the dewatering sections, the outflow channel is located in the lower part of pipeline 1, and the dehydrated oil extraction pipes 7 are located in the upper part of pipeline 1. In the water preparation sections, the inlet channels are located in the upper part of pipeline 1, and the drainage water extraction pipes in the lower part, The nozzles for the dewatered oil recovery are combined into a drainage oil collector 8, and the drainage water extraction nozzles 9 are assembled into the drainage water collection manifold 10. The sump works as follows. Watered oil through the overflow channel 5 enters the zone of moderate turbulence of the first dewatering section, where only very large drops are deposited. The emulsion is then divided into two streams, the lesser of which flows to the dehydration in the laminar sludge zone formed by the longitudinal horizontal partition 4 and the wall of the pipeline 1. the height of the transverse plate 6. The excess of the aqueous phase, the intermediate layer and deposits of mechanical impurities flow from the sludge through the transverse plate 6 into the zone of moderate turbulent spine, where together with the main flow e.lulsii they flow with high velocity in the next section. B (L: dewatering dehydration sections, the processes are repeated and the dehydrated oil is collected in the reservoir 8. The intermediate layer and the drainage water, the volume of which increases from section to section, flows into the drainage preparation section. This creates more favorable conditions for destruction emulsion and coalescence purification of drainage waters. In the drainage water preparation sections in the laminar zone, sludge is drained from emulsified oil. Part of the water phase is transferred through reservoir 9 to collector 10, and its excess phase flows through the internal channel installed at the top of the pipeline 1, to the next section of the preparation of drainage water,

The technical and economic efficiency of the proposed pipe sump design is determined by the best conditions for the withdrawal of a stable intermediate layer of an intact emulsion And deposits of mechanical impurities from the sludge zone. This improves the quality of oil dehydration due to more complete utilization of the useful volume of the settling zone. Fuller cleaning of the settling zone of the pipe sump from contamination

This is achieved by maintaining the aqueous phase layer on a horizontal longitudinal septum, which prevents the adhesion of the stable emulsion from adhering to the surface of the overflow channel and the pipeline. The emulsion rack and mechanical impurities, which are concentrated at the n-ft-water interface, are displaced (slid) along the underlying BODY-NOY layer from the laminar zone through the transverse plate and the moderate turbulence zone to,: exit from the dehydration section.
