(57) Abstract:The invention relates to means for separating oil from its mixture with water. The working elements of the device made in the form of pipes installed across the horizontal housing oblique longitudinal rows with the distance in the row equal to the period of the sinusoid, and the offset is relative to the pipe adjacent row by half the period of the sinusoid. Raised the pipe ends are fixed in the holes of the cage type squirrel wheel and lowered rely on it. Pipes are the input and output of the tangential openings. Thanks to this performance work items increases the rate of separation of oil from water through the use of along with gravitational centrifugal forces while maintaining the possibility of agglomeration of the particles of oil on the contact surfaces. 1 C.p. f-crystals, 7 Il. The invention relates to a device for the separation of oily emulsions and can be used in the oil, petrochemical and related industries.Known apparatus for separating liquid dispersion medium phase, comprising a horizontal body with nozzles source environment and removal of separated components accommodated in the housing of rabatment used longitudinal partitions sinusoidal profile located between the partitions gasket from wetting the dispersed phase (e.g., oil) material. The walls have holes to drain more easily, coagulating on contact surfaces of the gaskets and partitions of the component.A disadvantage of the known apparatus is a low separation velocity of light component, which occurs only under the influence of gravitational forces.The aim of the proposed device is the acceleration Department krupneyshego on contact surfaces of the component. This is due to the fact that the device for the separation of oily emulsions containing horizontal case with connections to the filing of the original emulsion and removal of separated components, and is placed in the frame work items that form between a thin-layer separation channels, work items are made in the form set obliquely across the body with the formation of longitudinal rows of tubes, the distance between which in each row is the period of the sinusoid, and the tubes of adjacent rows are shifted by half the period of the sinusoid, while the tubes fixed in the holes of the cage raised ends and rely on the yoke omitted ends, in the upper and lower parts of each tube is diametrically opposite tangential aerate concentrically mounted inside the tube outlet tube with tangential hole in the bottom, located opposite the tangential opening of a tube, the upper end of the outlet tube still fortified in the cage, and the bottom rests on it.The workflow element in the form of an inclined installed across the casing pipe with tangential inlet and outlet holes provides the use of the inner and outer surfaces of the pipes as a contact surface for the enlargement of the particles of oil, and the internal volume of the pipe for the effective separation of oil droplets in the field of centrifugal forces. The placement of pipes in rows, between which are formed thin-layer separation channels, increases the interaction of the flow with the contact surfaces and creates optimal conditions allocation of the shared components on the entire length of the housing. Installation of pipes in the clip based on her bottom ends at diametrically opposite tangential location of the holes on the ends of the pipe creates the conditions for an exit stream from a pipe in the canal zone smoothly, without undue disturbance that prevents mixing of the separated components.The use of tubes with concentric installed drainage pipes resting on the yoke and having a tangential the deposits is illustrated by drawings.In Fig.1 shows a General view of the device in section.In Fig.2 - General view of the device in a perspective view without the body.In Fig.3 - section "a-a" of Fig.1.In Fig.4 - node B of Fig.3.In Fig.5 - the node B of Fig.3 outlet pipe.In Fig.6 - cross-section "In-In" Fig.5.In Fig.7 - section G-G of Fig.5.A device for the separation of oily emulsions includes a horizontal body 1 to the pipe 2 the filing of the original emulsion, a pipe 3 for removal of petroleum products, pipe 4 for removal of heavy fractions and socket 5 for removal of clarified liquid. In the housing 1 on the guides 6 are installed ferrule 7 type squirrel wheel with stiffening rings 8 on the ends and the tubes 9 arranged obliquely across the body, at an angle of at least 45oto the horizontal. The upper end of the pipe 9 is rigidly fixed in the holes of the cage and the bottom rely on it. Along the casing pipe installed in a row on the length of the period L of the sine wave between adjacent tube rows. Pipe each successive row is offset relative to the pipe of the previous row by a distance equal to half the period of the sinusoid. In this arrangement the tubes are formed of thin channels of sinusoidal profile, communicating metamemory emulsion, and at the bottom - tangential hole 11, diametrically opposite the hole 10 and a lower reduced section.In the pipe 9 can be installed breather pipe 12 with tangential hole 13 in the lower part, opposite tangential holes 11 of the tube 9. The upper end of the outlet tube 12 still fortified in the cage, and the bottom rests on it. In the holder 7 has holes 14 for mounting the tube 9.The pipe 3 for removal of petroleum products fixed on the conical collector 15 mounted on the housing 1 at the top, and a pipe 4 for removal of heavy fractions - conical collector 16 in the lower part of the housing 1. Pipe 9 and the discharge tube 12 is made of a hydrophobic material, solid or porous, for example, polypropylene.The device operates as follows. The original oil-water emulsion under pressure fed through the inlet pipe 2 into the horizontal cavity of the housing 1, where it is evenly distributed in the working of thin channels formed by the pipe 9, and acquires a laminar flow in a sinusoidal path around the outer surface of the pipe. Part of the emulsion stream is directed through the tangential openings 10 in vnutrenniy is through the opposite hole 11, and the other part because the hole 11 is smaller holes 10, is displaced in the tangential hole 13 of the inner outlet tube 12, where the original emulsion on a spiral trajectory washes the surface of the pipe. Emulsion enable oil from the source of fluid under sinusoidal movement on the outer surfaces of the pipes and spiral on the inner surfaces of the pipes stick to hydrophobic surfaces of pipes, escalated the accumulation and float up to the entire length of the hull in the area of location of pipes, continuing to grow in size when bending pipes. Accumulating in the top of the conical collector 15, the oil is discharged through pipe 3 into the collection. Possible contamination from the work area precipitate, collected at the bottom of the conical collector 16 and discharged periodically through the slurry nozzle 4 for removal of heavy fractions.The clarified liquid, freed from oil and heavy contaminants (solids), is assembled in the housing 1 before the pipe 5 and discharged into the collection of the purified fluid. Using porous tubes, it is possible to increase the contact surface of the original emulsion with a hydrophobic material.Thus, the proposed device provides the silts centrifugal force in a vortex motion inside the pipes. And pipe perform simultaneously the functions of the contact surface, which is the integration of the particles of oil, which accelerates the Department, increasing productivity.When using pipes as working elements greatly facilitates cleaning of the device compared to a device with a gasket.The source of information
