Description

one

This invention relates to refining from oil.

A device for collecting oil from the surface of a reservoir is known, consisting of a flexible pipe with nozzles mounted on it and floats l.

However, this device requires the installation of a special pump to supply water to the nozzles, the installation of the nozzles at a certain angle to the water surface is complicated.

It is also known a device for collecting oil from the surface of a reservoir, including floats, a pump, a sump, an oil receiver, located in the central part of the receiving funnel and connected to the suction port of the C23 pump.

But in such a device, oil particles are ejected into the reservoir together with suction water, which are carried along by the mass of water and bypass the oil receiver, and also need to install a special pump or other pumping device to suck oil from the thickened part of the vortex funnel.

The purpose of the invention is to increase productivity and reduce the water cut of the collected oil.

This is achieved by placing an annular pipe around the receiving funnel, fitted with nozzles directed to the upper edge of the funnel, and connected to the pump discharge port, the suction nozzle of the latter being equipped with an ejecting insert located in the sump.

In this case, the transfer pump is located in one of the floats. The connection of the pressure pump of the transfer pump with the pipeline supplied with nozzles directed to the upper edge of the nozzle enclosed by the pipeline increases the performance of the device by intensifying the pulling of the upper layer of water with floating oil to the nozzle by reusing the water entering the receiving part of the transfer pump, and also returning to the collection zone for oil particles that are not captured by the oil inlet receiver. Virtually no oil is discharged into the reservoir. The installation of the sump on the suction inlet of the transfer pump reduces the water content of the collected oil at the expense of sludge, and the supply of oil from the oil sump to the sump and pumping water out of the sump is performed without the use of additional pumping devices. Placing the aero pump in one of the floats of the device simplifies the design of the device, since it eliminates the need to install a long shaft to drive the pumping pump, and also reduces the size of the device, since the drive is embedded inside one of the floats. FIG. 1 shows a device for collecting oil from the surface of a reservoir, a longitudinal section; on fi. 2 - the same, plan. The device consists of several, for example, three floats 1, in one of which a transfer pump 2 with a drive made in the form of a water turbine 3 is placed. The inlet connection of the transfer pump 2 with a discharge connection 4 and the ejector insert 5 connected to a nazack 6 are placed below the level of water 7 4a, and are connected via a pipe 7 to a settling tank 8 placed under the nozzle 6, the ejecting box 5, made in the form of a tapered pipe, may have another design, for example, in the form of a pipe equipped with a barrier d. Inside the receiving nozzle 6 is placed the refinery 9, connected to the settling tank 8. The discharge port of the pumping pump is connected to the pipeline 10 equipped with nozzles 11 directed to the upper part of the nozzle 6 In the upper part of the settling tank 8 there is a pipeline 12 for pumping oil products. The device works as follows. When the nozzle 6 is immersed below the level of the reservoir and when the pumping pump 2 is in operation, an axially symmetric centripetal flow is created, which leads to a decrease in the level of the liquid of the nozzle 6 and the formation of a surface identical to the surface above the mine discharge wall. significantly, sharply decreases sharp decrease in cross-section, and cross-section of the stream and around. It is the oil glyucus, the Cond: By the source Ef, there is oil oil 9, Water, after the oil is fed into nasais 6, through the ejection of the Insertion of the v discharge pressure pipe 4 of the non-pumping pump 2 to (;;;; 10 and creates a solid layer of water with oil. The associated run-off consists of water, entering the pumping pump Nose 2 through C connection, and oil, after hitting, oil, oil and water, and connecting with the captivity - Coy oil. , received, passing along the roKofd I nozzle into the. Water, or the oil tank and the mixture passing through the ejector insert 5, with an increase in The liquid flow creates a dilution of the hole and, through the pipe 7 from the bottom of the settling tank 8, sucks the water. Sludge onto the tank 3 is completely filled with liquid and the level of the liquid in it does not fall, because of the discharge: to the mixture from the oil receiver 9 enters the settling tank 8, where the sludge of oil occurs. As the oil-water mixture in the upper part of the settling tank is lowered, the oil is pumped to a vessel or another tank in the upper part of the settling tank. At the same time, the level in the settling tank 8 does not decrease, as the oil flows through the oil receiver 9. The combination of the well-known new prize increases the performance of the device and indicates the water content of the collected oil. During operation of the device, the velocity of the liquid entering the oil receiver increases dramatically, and the oil particles passing by the oil receiver are returned to the collection area. The invention The device for collecting oil from the surface of a reservoir, including floats, a pump, a sump, an oil receiver, placed in the central part of the receiving funnel and connected to the suction port of the pump, in order to increase productivity and decrease the water content of the collected oil, around the receiving funnel is placed annular
