Description

The utility model relates to the equipment of treatment facilities in the oil and gas complex, in particular to installations for cleaning soil affected by oil and oil products spills, for cleaning oil, used proppant for the purpose of its reuse, for cleaning sand used for collecting oil, processing oil sludge .

A known line for the processing and disposal of oil sludge, performed in block-complete design / Pat. 2026831 C1 of the Russian Federation, IPC 7 C02F 11/00, publ. 1995.01.20 /. The technological units include: coarse filtration unit, injection units, centrifugation unit, separation unit, oil product pumping unit, aqueous phase pumping unit.

A disadvantage of the known processing line is its structural complexity.

A known installation for cleaning oil-contaminated soils containing a container consisting of three parts: lower, middle, upper. The upper part is separated from the middle by means of a grid rigidly installed in the tank and has a pipe for oil products discharge located above the grid. In the middle part there are loading and unloading openings, and in the lower part there is a piston equipped with a net freely connected to it, and a pipe is provided located above the piston / RU 57740 U1, IPC ⁸ C02F 3/02, publ. 10/27/2006 /.

The disadvantages of the known installation are the complexity of the design, stationarity, high energy consumption.

A device for processing oil sludge containing a reactor, which is installed on the platform of the vibrator / RU 2111061 C1, IPC ⁶ V03V 9/02, publ. 1998.05.20 /. the reactor is divided into at least two compartments, has a loading device, a pipe for draining the liquid phase and a pipe for unloading solid inclusions, two pipes for supplying water with a flotation reagent and hot steam.

In the known device, small particles of soil are discharged together with water and, therefore, additional filtration of the liquid phase is required. For high-quality cleaning, additional equipment and high energy consumption are required.

The task to which the claimed utility model is directed is to develop a plant for the high-quality disposal and treatment of oil sludge

soils with the possibility of their secondary use without the addition of bioadditives and soil additives and does not require significant material and technical costs.

In the implementation of the utility model, the task is solved by achieving a technical result, which consists in simplifying the design of the installation, ensuring the effectiveness of the disposal and cleaning of oil-contaminated soils and reducing energy consumption.

The specified technical result is achieved in that the installation for cleaning oil sludge contains a housing, a tank for loading oil sludge. The case is divided by a partition into two chambers: a chamber for collecting oil products and a chamber for separating water from oil products, and is equipped with a removable bottom pan and nozzles for draining water and oil products from below. A tank for loading oil sludge is located in the chamber for collecting oil products, mounted on a frame, equipped with a lid and made of metal mesh so that a channel for the passage of steam is formed inside the tank. The housing is equipped with a bell, which is connected to the bottom of the tank to allow steam to be supplied into it. In addition, the housing is mounted on a support frame made with the possibility of its location on the vehicle. The cell size of the container is at least 0.05 * 0.05 mm.

Significant differences of the claimed utility model are the constructive implementation of various blocks: loading, unloading, cleaning in one housing. The constructive arrangement inside the container body, made in such a way that steam is supplied through it, allows for effective cleaning by ensuring the movement of steam inside the oil sludge, which allows separating oil products, liquid (water) and solid phases.

The utility model is illustrated by drawings, in which Fig. 1 shows an installation for cleaning oil sludge, a section, in Fig. 2 a loading tank for oil sludge, view A in Fig. 1.

Installation for cleaning oil sludge contains a housing 1, the bottom of which is a removable pan 2 for unloading solid particles of oil sludge (solid phase). Inside the housing 1, on a frame made of, for example, metal rods, a tank 3 is installed for loading oil sludge and made of thin metal wire with a mesh size of 0.05 * 0.05 mm according to the “pipe in pipe” type with the formation inside capacity 3 channels 4 for the passage of steam. On top of the tank 3 is closed by a cover 5. The housing 1 is equipped with a bell 6, which is connected to the bottom of the tank 3 to enable

supplying steam to it for processing oil sludge. The housing 1 is divided by a partition 7 into two chambers: a chamber 8 for separating water from petroleum products and a chamber 9 for collecting petroleum products. Capacity 3 and a removable tray 2 are located in the chamber 9 for collecting petroleum products. The housing 1 is equipped at the bottom on one side with a pipe 10 for draining oil products, and on the other hand with a pipe 11 for draining water. The housing 1 can be mounted on a supporting frame 12, made with the possibility of its location on the vehicle.

Installation works as follows.

Oil sludge is loaded into the tank 3, closed with a lid 4 and fed into it through the socket 5 under pressure of water vapor, for example from a steam-moving installation PPU.

Oil and oil products washed away by steam are discharged into chamber 8 for sludge. In chamber 8, water and oil products are separated and dusty solid particles (solid phase) precipitate. When filling the chamber 8 to the level of the partition 7, oil and oil products are poured into the chamber 9, in which there is a partial separation of oil and oil products and light paraffins. Water generated as a result of steam condensation is discharged through the pipe 11, the settled oil products are drained through the pipe 10. The solid phase of the oil sludge filling the removable sump 2 is sent either for reuse or, if necessary, for further processing.
