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, comprising 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 delaying large inclusions are made in the form of plates mounted parallel to the longitudinal axis of the housing.

The disadvantage of this technical solution is that the lattice cleans; it absorbs the liquid medium; 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 laying and floating; 1 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 continuous removal of hydrocarbons.

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

The problem is solved by using the proposed horizontal sedimentation tank for the separation of hydrocarbons and water, containing it; its body, inlet and outlet technological fittings, a lamp for draining sewage and vertical partitions, the vertical partitions being made in the form of porous and solid plates, between which there is a gap

IPC 01 D 17/02

a package of horizontal continuous plates located along the horizontal axis of the casing, with each plate of a package of continuous horizontal plates fixed to at least four flat supports rigidly fixed to vertical solid metal profiles.

Distinctive features of the claimed utility model is that the vertical walls are made in the form of porous and continuous plates, between which is placed a package of horizontal continuous plates located along the horizontal axis of the housing, with each plate of a package of continuous horizontal plates reinforced with at least four flat supports rigidly fixed to vertical solid metal profiles.

In FIG. 1 and 2 show a longitudinal section of the proposed horizontal sump and its section along AA. In FIG. 3 shows an enlarged fragment of element B.

The horizontal sump contains a cylindrical housing 1, input 2 and output 3 process fittings, vertical porous plates 4, vertical solid plates 5. Between vertical porous 4 and solid 5 plates, horizontal solid plates 6 are installed, made in the form of a package. Each plate of the bag is mounted on flat supports 7. The number of flat supports is at least four. Flat supports are rigidly fixed to the vertical profiles 8, which are connected to the inner surface of the housing 1 of the cylindrical horizontal sedimentation tank. Vertical profiles are solid. At the bottom of the housing 1 of the sump, a lantern 9 for draining sewage is filled.

Horizontal sump works as follows. Through the inlet process fitting 2, a mixture of water and hydrocarbons enters housing 1. On vertical porous partitions, the mixture is filtered and calmed. Next, the water-hydrocarbon mixture goes into production between the plates 6 of a package of continuous horizontal plates. The hydrocarbon mixture moves at low flow rates. Hydrocarbons rise to the top of the space between horizontal Aw / flW

bag plates and are collected in the upper part of the settled mixture. Then the hydrocarbons are moved under the vertical solid plates 5 and through the outlet technological nozzle 3 are diverted for further processing. Water, as the heavy part of the water-hydrocarbon mixture, is lowered into the lower part of the space between the plates 6 and collected at the bottom of the sedimentation tank and is discharged through the intake opening of the lantern 9 into the sewer. During the separation of the water-hydrocarbon mixture with water, solid and resinous cracking products are removed from the hydrocarbons, which are partially deposited on the surfaces of the elements of the sump. The decrease in deposition on solid horizontal plates is largely determined by their exact and stable spatial position. This is achieved by using a solid metal profile as vertical supports on which horizontal flat supports are mounted.

The use of a horizontal settling tank with a cylindrical casing with a stack of horizontal continuous plates mounted on flat supports mounted rigidly on vertical solid metal profiles inside it allows aligning the position of horizontal plates, eliminating their unevenness, which leads to local flow swirls and deterioration of the water-hydrocarbon separation mixtures. In addition, the use of vertical solid profiles makes it possible to establish levels of flat supports.

All this allows you to effectively separate the water-hydrocarbon mixture into water and hydrocarbons. The design of the horizontal cylindrical sump is easy to manufacture, reliable and stable in operation.
