Description

Description of the invention

The portable small-sized device is designed to eliminate emergency spills of petroleum products from the surface of 2 water. It can be used as part of a boom barrier during bunkering of ships and transshipment of petroleum products in sea and river ports.

The well-known oil collection device "Svetlomor"/1|, working on the principle of the threshold effect, which has two receiving tanks, into which the upper layer of water with oil products merges, and the collected oil products are pumped to the shore by an axial pump. The main drawback of this design is the flow of collected oil products in 710 drainage system, which reduces the efficiency of its operation.

The closest in technical terms is a portable vortex-type oil collecting device (21), which is a conical funnel with an oil receiver in the center. The conical funnel with a container for accumulating the collected oil products is held on the water by three floats, and the upper edge of the funnel is placed below the water level. During operation of the axial pump, the collected oil products are accumulated in the central part of the funnel in the form of a submerged circular hydraulic cylinder, and then pumped into the storage tank.

The main disadvantage of this design is a significant decrease in the efficiency of the device in the presence of surface currents and turbulence due to the instability of the roller position, during which part of the oil products flows with the main flow through the funnel, and water enters the oil receiver.

The basis of the invention is the task of improving the conditions for the accumulation of collected oil products, in which the upper layers of water with oil products merge through a floating annular spillway into a cylindrical container, which is placed below the water level, while the pressure above the spillway is set automatically in accordance with the optimal flow of water that flows out through the axial pump, and the spillway rises above the water level behind the device in the process of pumping out the collected oil products from the tank, due to which favorable conditions are provided for the accumulation of oil products in the cylindrical tank and their subsequent pumping into the storage tank. with

The portable oil-collecting jetty is a small-sized, non-self-propelled oil-collector, which consists of an open cylindrical container placed on three floats below the water level, and the container holds inside a floating cylindrical spillway threshold, which is arranged with the possibility of free vertical movement, as well as a bucket turbine, which placed on one shaft with an axial pump, above the inlet of which there is a ring deflector of the flow, fixed to the water-impregnated bottom. at

The essence of the invention is explained by drawings. Figures 1, 2 and 3 show a general view of a portable oil collecting device in the mode of collecting oil products and pumping out collected oil. Fig. 4 shows the scheme of using the device as part of the boom barrier. at

The portable oil collection device consists of an open cylindrical container 1, which is kept afloat by three floats 2, 3 and 4 (Fig. 1, 2, 3). A floating spillway 5 is placed inside the cylindrical container 39, which is kept afloat by three floats 6, 7 and 8 with the ability to move vertically. A ring stop 9 is placed in the lower part of the spillway threshold. A similar stop ring 10 is attached to the inner wall of the tank. In the center of the threshold 5, a cylindrical limiter of the oil receiver 11 is attached. In the upper part of the tank, there is a bucket turbine 12, and in the lower part, an axial pump 13 on one shaft with bucket turbine wheel. A cylindrical flow deflector C is placed above the axial pump inlet, which is fixed to the water-impregnated bottom 15. A pipe 16 with a diffuser in the upper part is placed above the flow separator c 14. On the outer side of the cylindrical container, the intermediate

With" floats 2, 3 and 4, containers 17 are placed for additional buoyancy. A pressure pipe 18 is placed on the float 2, on which there is a nozzle 19 for supplying water to the bucket turbine, a non-return valve 20, a tee 21 and a flange 22 for connecting a flexible hose 23. Inside the float 2 there is a suction pipe 24, which is connected to a vertical pipe 16, and a non-return valve 25. In front of the circular spillway there are grates 26, outside the spillway - a ring absorber of the energy of the falling jet 27. The PNI-2 oz kit includes a receiving vacuum container 1 (Fig. 4), a device control system 2, which consists of an ejector for creating a vacuum and the center of the circulating pump for supplying water to the bucket turbine 12 (Fig. 1), and a flexible and pressure-suction hose 3. -I 20 The portable oil collecting device works as follows.

The flow of the surface layers of water with petroleum products into tank 1 through the floating annular spillway of 5 ml occurs when the water level in the tank decreases and the simultaneous lowering of the annular spillway due to the pumping of water from the tank with the help of an axial pump. During this, a balance is established between the flow of water that enters the tank through circular spillways and the water that is pumped out by the axial pump, while the flow rate of 25 water that is pumped out is taken as optimal, which excludes the leakage of collected oil products through

GF) axial pump down. In this way, the pressure over the edge of the annular spillway is automatically regulated. After filling the container with petroleum products to the critical position of the oil-water boundary, the collected petroleum products are pumped into the receiving vacuum container 1 (Fig. 4), which is placed on the pier or the tug deck. During the pumping of the collected oil products, the water supply to the bucket turbine is stopped, the upper edge of the threshold floats 60 above the water level behind the device, the ring stops are connected, while there is no leakage of oil from container 1 to the water surface. The upper edge of the cylindrical limiter 11 rises and is located below the oil level, which ensures the pumping of all collected oil products from the container. After pumping out the oil products, the collection mode is resumed by turning on the center circulation pump and supplying water to the turbine 12. If there are two flexible hoses between the control system 2 and PNP-2, the pumping process can be carried out without stops. One flexible hose will work in the pressure mode, and the second - in the suction mode.

The device fully complies with fire safety requirements and does not require maintenance personnel.
