Description

HORIZONTAL Sump

The utility model relates to systems for the separation of hydrocarbons and wastewater and can be used in the oil and petrochemical industries.

Known grill installed in front of the suction pipe of the pump for pumping wastewater, including a housing and elements housed in the housing to detain large inclusions (AS USSR No. 279483, IPC C 02 C 1/18, publ. 21.08.70). Elements for retaining large inclusions are made in the form of plates mounted parallel to the longitudinal axis of the housing.

The disadvantage of such a technical solution is that the lattice detects the liquid medium from its contents: it contains external inclusions, but does not separate hydrocarbons and water.

Closest to the claimed technical solution is a horizontal sump (AS USSR No. 1754661, IPC C 02 F 1/10, B 01 D 17/02 publ. 08/15/92) containing a housing, collectors for supplying and discharging water, a device collection of petroleum products, vertical rails; 1 and floating partitions with the formation of ejection windows between them.

The disadvantage of this device is its low productivity with a high content of organic compounds and the inability to conduct effective separation of hydrocarbons and water with an unbroken removal of hydrocarbons.

The objective of the utility model is to improve the quality and efficiency of the separation of hydrocarbons and wastewater.

The problem is solved by using the proposed horizontal sump for the separation of hydrocarbons and water containing a housing, inlet and outlet technological fittings, a lamp for draining sewage and vertical partitions, while the vertical partitions are made in the form of porous and solid plates, between which is placed

a package of horizontal solid plates, and a lamp for discharging wastewater is asymmetrically filled with the vertical axis of the housing and has a length of not more than 2/3 of the length of a package of horizontal solid plates.

Distinctive features of the claimed utility model is that the vertical partitions are filled in the form of porous and solid plates, between which are spaced; a packet of horizontal solid plates is provided, and a lantern for draining wastewater is asymmetrically drawn to the vertical axis of the housing and has a length of no more than 2/3 of the length of the package horizontal solid plates.

In Fig.1 shows a longitudinal section of the proposed horizontal sump, in Fig. 2 is a section along A-A of FIG. 1, and FIG. 3 is a section through FIG. 1 along BB.

The horizontal sump contains a slotted housing 1, input 2 and output 3 process fittings, vertical porous plates 4, vertical solid plates 5. Between the vertical porous 4 and solid 5 plates, horizontal solid plates 6 are installed in the form of a packet. The package of horizontal solid plates in the direction of the axis of the cylindrical housing 1 of the sump is made parallel to the axis of the housing, and in the direction perpendicular to the axis of the housing, with an inclination towards the opening of the lamp for discharging waste water. Plate 6 of the package of horizontal solid plates in the direction of the hole of the lamp does not reach the wall of the housing, forming a space 7.

Lantern 8 is made with mixing (asymmetrically) with respect to the vertical axis of the cylindrical body. Asymmetric mixing of the lantern and the direction of inclination of the plates of the package of horizontal solid plates coincide. Lantern 8 is elongated along the length of the cylindrical body and has a length of not more than 2/3 of the length of the package of horizontal solid plates.

Horizontal sump works as follows. A mixture of water and hydrocarbons enters through the inlet 2 of the process fitting into the housing 1 of the sump. On vertical porous partitions, the mixture is filtered and calmed. Next, the water-hydrocarbon mixture enters the space between the plates 6 of a package of continuous horizontal plates. The hydrocarbon mixture moves at low flow speeds horizontally along the axis of the housing 1. In the direction perpendicular to the axis of the housing 1, due to the position of the horizontal solid plates with an inclination towards the asymmetric hole of the lantern 8, the carbon-carbon mixture is separated. The hydrocarbon mixture rises to the upper part of the space between the horizontal plates of the package and up along the inclined plane of the horizontal solid plate.

The water part, as heavy, falls down and mixes down along the inclined plane of the horizontal continuous plate and through the space 7 it enters the hole of the lantern 8 and then into the sewer.

The separated light hydrocarbon portion rises up and further under the vertical continuous plates 5 and is discharged from the sump for further processing through the process fitting 3.

Mixing the opening of the lantern 8 relative to the vertical axis of the cylindrical casing provides acceleration of the discharge of wastewater falling into space 7, and the use of a lantern longitudinal with respect to the axis of the casing of the mold, with a length of not more than 2/3 of the length of the horizontal solid packet, plates also accelerates the discharge of wastewater. All this increases the intensity of the discharge of wastewater, thereby accelerating the sedimentation of the water-hydrocarbon mixture. It should be noted that a significant amount of hydrocarbons in wastewater is not observed. The design of the horizontal sump is easy to manufacture, reliable and stable in operation.
