: DEVICE FOR COLLECTING OIL POLLUTION

WITH THE SURFACE OF RESERVOIRS.

:. .Pshenichny B.P.

Petroleum and petroleum products are ONNERSHI from the main pollutants of fir water bodies. Getting into the water as a result of leaks, spills, accidents and drupshi ways, oil and oil products spread over the surface of the Eodoys, covering large areas with a thin, surface film. The oil film is weakly destroyed and quickly closes when its integrity is violated.

To cope with oil pollution / 1 that has got into the pond and has collected tag / 1 oil film, various types of creeping are used for: citizens (booms) that prevent oil from spreading, special hoses - oil sumps and various devices, collect the 1st oil - Wed in / measures.

An analogue of the proposed device for collecting oil pollution on the surface of water bodies can be the Reinverft device, which is a floating funnel submerged under water, from which water is pumped out by a pump (Nelson Smith, Oil and Marine Ecology. 313D-EO Progress, Moscow, 1977 , p. 2E8, fig. 9-ZA). The closest device is a tube immersed in water with a head (floating in the water on a float, working when the sea is rough (Autosvadet. 1714040, kp. E 02 V 15 / 04.1992).

The invention relates to the protection of the aquatic environment. The purpose of the invention was to expand the capabilities of the device by using it for CO2-2 oil pollution from the surface of water bodies in waves as in open waters. and in places of constant (probable) income / in a reservoir (in ports, in oil and gas field :).

A device for collecting oil pollution from the surface of water bodies (Figure 1) is a reservoir (1), the upper end of which is equipped with an annular / restrictive element (2), serving as a seat for a floating check valve (3) having a bulging surface . The lower end of the tank can be narrowed and pass into the pipe on which the load is fastened and the sleeve and the hose can be attached. The tank is lowered into the water on the suspension (4) from an immovable (carry // bekoli) object (from the shore, adera barrage, platforms / s), or from a submerged, floating object that tracks waves (from a float, buoy, melt, 1,) . In the first case (the reservoir is not exposed), the upper end of the reservoir is covered with water. When the crest of the wave and the eye passes: it appears above the surface of the water when it is in a hollow between the waves. In the second case (the tank moves together with the floating object), the tank also crosses the water line, either under water or above its surface (the surface of the reservoir is stationary). The operation of the device for collecting oil pollution is carried out as follows ( Figure 2). When waves in a reservoir, when the upper end of the tank (1). crosses the siphon of water, covered with oil CryL and is under water (Figure 2 a), a floating valve (3), is pressed to the seat of the annular restrictive element (2), closes the inlet of the tank, and does not allow water to penetrate into the tank , nor get out of it. At this moment, the oil film on the surface of the reservoir (above the reservoir), due to cmiai molecular cohesion, closes. When the device, crossing the edge of the water covered with an oil film, is above the surface (Fig.2 b), the valve (3) opens (falls under gravity, of its own weight) and water enters the tank together with the oil. The convex surface of the valve facilitates the flow of oil into the tank. At this point, part of the water that had come earlier earlier is poured through the lower end of the tank - and lighter oil is inside the tank under the hood. In the next cycle of operation, when the device’s reservoir is again under water (Fig. 2 c), the oil film above n1 / 1 (on the surface of the reservoir) closes again, and the inlet of the reservoir is again valve-sealed, preventing water and the oil film from getting into -in the tank, nor pour out of it. At the next moment, when the-reservoir again crosses the water edge and is above the surface of the reservoir (F1P.-2 g), the valve opens and the next portion of water with oil is captured by the reservoir. At this point, part of the water is again poured through the lower end of the tank, and oil again enters the tank- (under the valve) and P13 does not pour out when the tank moves under water (Figure 2 e). - Thus, using wave anergy, the upper end of the device’s reservoir repeatedly intersects the surface of the reservoir covered with oil pollution. Lighter oil is collected in the tank under the valve. --2 X. , - 3 f HOM and does not pour out of it, while heavy water, compared to oil products, falling into the oil reservoir with oil is poured through its lower end.After a certain time, the device’s tank is filled with oil pollution. Oil from tank 1i1 can be pumped out by the pump through its upper end. If a hose or hose is connected to the lower end of the tank, the device can be lifted, and the ceft from it is drained through the sleeve into a container. The hose ilrg hose can be brought under water from below to a special container installed in the reservoir. In this case, the device may continue to operate when the tank is full of oil. Oil from it (through a hose or sleeve) will flow into this tank, displacing water from it.

A device for collecting oil pollution can also be used to collect polluting objects (floating garbage, used sorbent, etc.) floating on the surface of a reservoir. Floating objects on the surface of the reservoir, as well as oil, enter the tank when they cross the water line and are held under the riapan. To-facilitate the entry into the tank of volumetric floating objects, the surface of the floating valve is given a more convex shape (hemisphere, -inap). about
