The invention relates to the field of environmental protection and is designed to collect surface water floating polluting liquids, such as oil, gasoline or the like, in particular, the contamination of oil or gasoline water pomogut to leak large amounts of oil, which form on the water surface oil carpet or contaminated oil sea water. All previous measures to remove such oil carpets or oil polluted sea water with the water surface was ineffective. For example, the oil carpet or oily sea water was shielded floating barriers, allowing them to suck from the water surface. This is only possible when a small sea of excitement, and the volume of sucked in General not correspond to the required number. High sea excitement throws oil carpet or contaminated sea water through these floating barriers.

Even the use of chemicals due to the formation of odor and other subsequent events, such as the deposition of petroleum compounds on the seabed, were ineffective.

Known installation to absorb oil carpets, using nefteokislyayuschey station, consisting of several components and assemblies, oil carpets vacuumed below water level /FR 2673214 A1, 28.08.92/. In one embodiment of this installation /Fig.7/ there floating in the water nefteuloviteli tank, which is on the upper parts of the walls is palagallo and through the openings in the wall sections included in catching the tank. Himself catching tank connected to the suction pipe, which is stored in a capture tank sucks liquid from the tank down and forwards through pipelines to the auxiliary boat or similar. This setup has the advantage that more or less thick layer of oil is constantly going under the floating body and goes to the tank for recovery. The buoyancy tank for recovery, as well as a reception surface for suction of fluid in catching the reservoir determines the size or amount of the received fluid. As a consequence, only with difficulty can be separated between the oil layer and the rest of the water environment, which under certain conditions can lead to the absorption of a large number of only slightly contaminated water, and thus may deteriorate the efficiency of the installation.

Known for another installation to absorb oil carpets /DE 2721108 A1, 23.11.78/. In this very cumbersome installation in the center of the floating frame structure is a body in the form of a truncated cone with lateral inlet holes for making oil polluted surface water. Here the exterior ends of the frame floating bodies, the thickness of the absorbed layer of oil carpet is not regulated.

Also known Nefteotdacha installation, which is made harshorne in the form of a floating body /FR 2410093, 22.06.79/ this sets the oil carpet is made on the upper side of the floating device through the entrance slit. Thus, the correct position afloat and depth of such a device to determine the number of falling on the upper side of the oil liquid.

The closest known of the present invention is a device to absorb floating on the water surface of polluting liquids, such as oil, gasoline or the like, containing submerged under the surface of the water receiving tank, which has in the upper zone is preferably annular floating body and directly under the floating body inlet for receiving absorbed by the fluid and at least one suction pipe injection pump for transporting absorbed in the receiving tank of the liquid to the station removal /FR 2069926 A, 10.09.71/.

The disadvantage of this known device is the inability to control the depth pohoto reduces the performance of the device and reduces its effectiveness and efficiency.

The present invention is directed to solving the task of creating nefteokislyayushchego device, which allows a very focused and thereby effectively absorb the oil carpet or oil polluted sea water. However, the installation must be designed so that it could absorb the oil carpet or contaminated oil-water on a large surface so that it can be used after a tanker accident in the port facilities, coastal waters, the high seas and closed lakes or other bodies of water, and could serve well as providing system having a drain, a floating derrick-crane for offshore drilling or damaged pipelines.

The solution of this problem is achieved in that the device to absorb floating on the water surface of polluting liquids, such as oil, gasoline or the like, containing submerged under the surface of the water receiving tank, which has in the upper zone is preferably annular floating body and directly under the floating body inlet for receiving absorbed by the fluid and at least one suction pipe from the supercharger is but the invention provided below the floating body and surrounding the receiving tank suction funnel bath, the upper edge of which is located relative to the bottom side of the floating body with suction gap, determining the width of the intake fluid stream, while receiving tank made vandoorne or cylindrical, and means providing buoyancy mentioned floating body is designed in such a way that the latter is largely located on the water surface.

In some cases, the design of the proposed device suction tub is made of a parabolic shape and is installed with the possibility of changing the width of the inlet gap between its top edge and the bottom side of the floating body, with the width of the above-mentioned gap does not exceed 300 mm

The device 1 to absorb floating on the water surface of polluting liquids in accordance with the invention consists of (see Fig.1 and 2/ of the cylindrical main body, forming a skimmer catching tank 2 with a large number found in the upper part of its side surface openings 3, which are made in the form of a horizontal longitudinal slits or round holes. Radial or spherical remove the dome 4 overlap covers the upper portion of the main body and also has a slotted inlet 5, which PR is and 2 for the oil of the Mat 6, remove from the water surface 7. Oil recovery vessel 2 is surrounded in the upper zone of the ring, namely, if necessary, divided into ring segments of the floating body 8, which is inside a large number of air channels 9. Air channels 9 serve as cameras, providing buoyancy, and, if necessary, are made in such a way that the floating body 8 by analogy with arm is in principle on the water surface 7. Air channels 9 can be filled with air. They can also be filled with other means providing buoyancy. As follows from Fig. 1, the air duct 9 can consist of several koltseobrazno passing separate chambers, who intensively can be filled with air or other lifting means. The outer diameter d1the floating body 8 is approximately 7 m /d17m/. The outer diameter d2catching tank 2 is about 3 m /d23 m, height h2for example, about 2.5 m /h22.5 m/. The height h1the floating body 8 is about 0.5 m /h10.5 m/.

Directly beneath the floating body 8 is a parabolic-shaped suction tub 10, the upper edge 11 which city is the largest, the purpose of the device 12 height adjustment. The maximum adjustment of the stroke shown in Fig.4 by the symbol S and is approximately from 250 to 350 mm (S 250-300 mm). The lower position of the suction baths designated position 10.

The device 12 height adjustment contains lead screw 13 and nut 14. The drive screw 13 by using a drive motor 15 (see Fig. 5/.

In addition, from Fig. 1 and 5 it is seen that the suction tub 10 has a supporting buoyancy body 16 made, for example, in the form of airbags, the volume of which optionally may change.

In the oil collecting tank 2 includes three symmetrically located relative to the Central axis 17 of the symmetry of the suction pipe 18, the lower end 19 which comes about to the closed bottom 20 oil storage tank 2. In the suction pipe 18 includes high pressure pumps 21, which are designed to transport collected in the oil collecting tank 2 oil or oily liquid. The suction pipe 18 protrude from the dome 4/, see Fig. 1-2/ and are in the upper area of the flexible hose 22, which are designed for flexible connection to the other who is the stabilizer 23 with the supporting bases 24. The regulator 23 has a top wall section several receiving holes 25 through which water can enter. Also in its bottom 26 there are other receiving apertures 27 through which can flow the water. In accordance with this stabilizer 23 having in cross section the shape of a truncated cone, filled with water and with a strong Maritime excitement behaves similarly with the speakers down a stabilizing keel. This enables the device 1 to absorb relatively stable oscillations with a strong Maritime excitement.

In the lower zone of the cylindrical catching tank 2 is the pen 28 of the steering wheel with the screw 29 steering roll, which are designed to stabilize the position of the device 1 to absorb.

The device 1 to absorb can be transported using a transport and locking lugs 30 and fixed in a certain position.

The suction pipe 18 is held within the safety of the tank 2 by means of fixing bridges 31, which are additionally equipped with dampers 32. Above the dome 4 are also mounting crosspieces 31 with the dampers 32 for three symmetrically suction pipe 18. However, here odsustvo 1 is designed to absorb with large areas and large volumes of oil carpets and oil-contaminated freshwater and marine waters under the water surface. The device 1 is manufactured in a compact design and are collected from resistant to sea water, acids and fire units, and auxiliary functional blocks. Cylindrical catching tank 2 forms at the base of the device 1 and receives when it runs approximately from 2 to 4 m /h22-4 m/ and a diameter of about 3 m /d23 m/ a large amount of absorbable oil carpet. The quality of the buoyancy device 1 is provided with a separate phone 8 and 16 maintain buoyancy, and with the help of free volumes catching tank 2, and a floating body 8 should be placed mainly on the water surface to form the necessary input slit width S between the floating body 8 and the suction tub 10. The outer diameter d3suction bath 10 approximately corresponds to the outside diameter d1the floating body 8 (see Fig.2/. However, the diameter of the suction bath 10 in accordance with the image in Fig.1 can also be somewhat smaller.

During operation of the device 1 to absorb oriented in the water so that the oil Mat 6 is constant at the level of the lower edge 33 of the floating body 8, i.e., water is yavlyaetsya using device 12 height adjustment so the gap S approximately corresponds in magnitude to the thickness of the oil of the Mat 6. Thus, the pop-up on the water, the oil is removed very purposefully. The entrance of the oil carpet 6 in the input slit 34 /indicated in Fig.1 by the arrow 35/ allows oil to flow to the carpet 6 through the inlet 3 into the tank 2 /arrow 36/. Coming into the oil collecting tank 2 oil is transported in the arrow 37 direction through the suction pipe 18 into the corresponding bunker vessel /arrow 38/.

Made in the form of a truncated cone stabilizer 23 has a height of about 1 m /h31 m/. It prevents the device 1 to absorb tip over even when high seaways, or he gives the whole device 1 is stable, adapted to the respective Maritime excitement of the situation.

The upper dome with 4 inlet holes 5 allows you to receive oil at the rolling waves, so that in this way the oil and contaminated water can flow into the oil collecting tank 2.

In accordance with the image device 1 to absorb in Fig. 4 and 5, the inlet 3 provided in the oil collecting tank 2 may be made in the form of slots or from yuusha bath 10. The inner section 39 of the wall of the suction bath 10 is made in the form of a cone of height h5where are the inlet 3. Inlet 3 prevent the penetration inside oil storage tank 2 foreign bodies, such as drift wood and the like.

Parabolic suction tub 10, ushiroyama height, targeted increases the suction effect on the oil carpet 6. In particular, thanks esteruelas width of the gap S purposefully absorbed only such liquid which is contaminated with oil. Aligning parabolic suction bath 10 by using installed on rollers prismatic guides and, in particular, with the regulating device 12.

The top edge 11 of parabolic esteruelas suction bath 10 is always below the water surface 7, so that the oil carpet 6 inevitably flows through the thus formed an entrance slit 34 in the device 1 to absorb. This forced the filling device 1. To fill the device 1 may be additional valves flooding. If oil collecting tank 2 is filled with oil, in the work vklyuchayuthie operation of the device 1 to absorb.

Pen 28 steering, as well as the screw 29 steering roll prevent rotation of the device 1 to absorb around its own axis in a stationary mode or in the tow bundle. Rudder roll can be articulated with the navigation system and can be managed remotely or maintain manually.

As can be seen from Fig. 5, the upper outer edge 11 of the suction bath 10 can be made with a small fracture at an angle 140orelative to the conical outer side surface 40. This results in the "plate edge, which delivers targeted admission of the oil layer.

When starting the device 1 it is in the first zone of operation is loaded only water 41, 41 and the water from the bottom of the bottom 42 of the device 1 is fed along the transport pipe 43 to the high-pressure pump 44. This high-pressure pump 44 exerts a constant pressure on both the check valve 45. As a result of this also prevents drying of the high-pressure pumps 21. Made in the form of centrifugal pumps high-pressure pumps 21 can operate hydraulically, electrically or pneumatically.

The first part of the water in circulation the t regulatory body 47. The Supervisory authority 47 measures the density of the medium, and controls the three-way valve 46.

As soon as the Supervisory authority 47 register sucked water three-way valve 46 is activated so that the water pipeline 48 is pumped back to the bottom 42, which is clearly below the surface 49 of the oil pollution inside the tank 2 /water surface showing the position of 50/.

As soon as the Supervisory authority 47 register Wednesday - oil -, three-way valve 46 is switched to the second phase of operation, and contaminated oil through is made in the form of a centrifuge separator installation 51 is pumped in catching the reservoir 52, for example, a tanker, a receiving tank or the like. The Supervisory authority 47 to distinguish between water and oil in combination with the separation installation 51 ensures the implementation of the optimal separation sucked oil and water, so that it is possible to delete only sucked oil.

Therefore, high-pressure pump 21 is sucked off through the pipe 53, basically just floating at the top of the oil, which must be removed. Below the water can be removed by using more what am 54. Shut-off valves 55 determine the direction of flow through the high-pressure pumps 21.

In Fig. 6 also shows that the separation setup 51 to the bottom 42 of the tank 2 leads another pipeline 56 to back to pump excess water.
