Pipes, gutters, control valve, mesh fence made of steel.

The foundation is made of concrete V-20, reinforced with a spatial frame Kr-1 and Kr-2 of rods with a diameter of 12 mm, contains a concrete blind area and side coating waterproofing with bituminous mastic.

The mesh fence is attached to the tank using fasteners.

The mouth of the underground water source has a size of 300 × 300 mm.

The inventive device is illustrated in the figures.

In FIG. 1 shows a device (top view).

In FIG. 2 shows a sectional view of the device (side view).

The inventive device is a trap for oil (oil trap) and consists of the following elements.

The reservoir 1 is made of reinforced concrete and is located on a monolithic concrete foundation 2, installed around the mouth 3 of the underground water source.

One of the walls of the tank 1 contains two holes in which are installed: the main pipe 4 for the intake of purified water and an additional pipe 5 for the intake of purified water during the flood period.

Moreover, the additional pipe 5 is located above the main pipe 4, because during the flood period the water level in the river is higher.

The main pipe 4 contains a crane (gate valve) 6 to prevent the ingress of flood water into the tank.

The ends of both pipes 4, 5 inside the tank 1 are located at one or at different levels.

The minimum distance from the ends of the pipes 4, 5 to the bottom of the tank is 0.2 m.

The ends of the pipes 4, 5 in the tank are located at a distance of 2 m from the mouth.

The level of the additional pipe 5 is due to the level of flood waters that flood the coastal zone and are above the level of the main pipe 4.

The hole of the additional pipe 5 is located in the wall of the tank 1 above the hole of the main pipe 4 for the intake of purified water.

Parts of pipes 4 and 5 located in the tank 1 have a 90 ° bend, i.e. located at an angle of 90 ° to the bottom of the tank 1.

On top of the tank 1 is closed by an opening metal mesh fence 9 with mesh sizes of 50 × 50 mm.

Pipes 4, 5 at their outer ends protruding from the reservoir 1, contain grooves for draining the purified water into the reservoir.

Pipes 4, 5 with grooves, control valve 6, mesh guard 9, pipe bends are made of steel.

The foundation 2 is made of concrete V-20 and reinforced with a spatial frame Kr-1 and Kr-2 of rods with a diameter of 12, and with side coating waterproofing bitumen mastic.

Foundation 2 contains a concrete blind area to enhance the strength and stability of the entire structure of the device.

The tank 1 and the foundation 2 are a single monolithic device.

The walls of the tank 1 are made with metal strapping for additional structural strength of the device.

Overall dimensions of the tank 1 - 6000 × 5000 mm, height 1800 mm, wall thickness 500 mm.

The mouth 3 of the underground water source has a size of 300 × 300 mm.

The outer diameter of the pipes 4 and 5 is 159 mm, the wall thickness is 6 mm.

The width of the gutter is 250 mm, the radius is 200 mm.

Branches have parameters of 150 × 8 mm.

The maximum filling level of the tank 1 is 1800 mm, of which 1500 mm is the maximum water level, above is oil. The device operates as follows.

Contaminated water flows directly from reservoir 1 to the ground.

Upon receipt, the liquid filling the tank 1 settles, resulting in a process of separation of water and oil in a natural way due to the difference in their specific gravities.

The separation of water from oil occurs almost immediately when fluid enters the tank 1.

Oil floats up, thereby forming two layers: the bottom is water purified from oil, and the top is oil.

When the device starts, the control valve 6 of the main pipe 4 is closed, after the accumulation of water above the level of the main pipe 4, the adjustment valve 6 is opened. Moreover, the level of the oil film does not fall below the level of the main pipe 4.

Next, clean water enters through the main pipe 4 and then through the gutter into the reservoir.

Filtered oil does not sink to the bottom, but floats until pumped over the surface of the water.

The oil accumulated in the tank in the amount of 4 m ³ once every 2 months is pumped out by a vacuum barrel directly from tank 1 and transported to the oil preparation unit.

Additional pipe 5 is used during the spring flood, when the water level in the natural reservoir increases.

During the flood period, the water level rises, there is flooding of the area around the reservoir 1. In this case, the water level is higher than the main pipe 4, but below the additional pipe 5 (above the additional pipe 5, the water never rises). To prevent the ingress of flood water into the tank 1, the control valve 6 on the main pipe 4 is closed, the water in the tank 1 begins to flow out through the additional pipe 5.

The use of the claimed device will eliminate the ingress of oil into natural reservoirs, reduce the negative impact on the environment, and improve the ecological safety of the region.

The device passed successful tests during the oil development near the Sheshma River.
