The invention relates to environmental protection, in particular to the technique of cleaning liquids from floating petroleum products.

The aim of the invention is to increase the efficiency of the device with a small thickness of the oil layer.

Figure 1 shows the device, top view; figure 2 - section aa in figure 1; on fig.Z - section BB in figure 1; figure 4 - node I in figure 1; in Fig. 5, view B in Fig. 3; figure 6 is a section of the GG in figure 4.

The device includes inlet 1 and outlet 2 channels, tank 3, divided by partition 4 with lower 5 and top 6 edges to section 7 with floating oil products and section 8 without floating oil products, directing drains 9 rigidly fixed on the bottom 10 of tank 3. The partition 4 is provided with floats 11, guiding elements made in the form of a core 12 with a rigidly fixed vertical plate 13 moving in racks 9 with a vertical slot 14. The space between the vertical wall 15 of the container 3 and the guiding racks 9 sealed by sealing element 16 from a rubber hose. The partition 4 is installed at an acute angle to the fluid flow contaminated by floating oil products coming out of section 7 on vertical plates 13. To give strength and rigidity to the connection of partition 4 to plates 13 there are fins 17, the device is equipped with a drive 18 of pump 19, the suction line through corrugated the elastic pipe 20 is connected to the pipe 21 welded at a right angle into the partition 4.

The device works as follows.

In the absence of liquid in the tank 3, the partition 4 with its lower edge 5 contacts the bottom 10 of the tank 3. The upper edge 6 of the partition exceeds the estimated level of the liquid in the tank 3. The liquid contaminated with floating oil through channel 1 enters section 7 and fills it up until the liquid level reaches the floats 11. With further filling of the section 7, the floats 11 provide a brief rise of the partition 4 with the formation of a gap between its lower edge 5 and the bottom 10 of the tank 3. Through the gap the liquid from section 7 p steps in section 8 due to the presence mounted for vertical movement partitions 4 with floats 11, responsive to the change in liquid level in the vessel 3.

Subsequently, as the contaminated liquid is supplied through channel 1 in sections 7 and 8, according to the law of communicating vessels, a general level of liquid is established, characterized in that the surface of section 7 is contaminated with floating oil products, and section 8 is free of them. The liquid from section 8 is pumped out by pump (not shown) of type 9МГР or ЗК-6 for reuse in the circulating water supply. Pump 19 of type 9МГР or ЗК-6 through suction pipe 20 and pipe 21 pump out a layer of petroleum products floating in section 7, and placing the partition 6 at an acute angle, for example, 45 ° to the incoming oil-contaminated fluid flow in section 7 welded under the pipe my angle pipe 21 provides selective selection of a layer of oil, the thickness of which is determined; vertical projection of the cross section of the pipe 21, presented in the form of an ellipse (Fig.6). With this, the opening area of the suction inlet 21 of the pump 19 is not reduced. Dipping the pipe 21 into a liquid of 2–3 mm ensures elimination of air suction and selective removal and removal of floating oil from section 7. The intensive supply of contaminated liquid to section 7 or pumping out the purified liquid from section 8 is accompanied by a corresponding vertical displacement of the partition 5, ensuring effective and reliable operation of the device.
