Title: Device for removing and/or limiting oil floating on a water surface or standing on a solid surface.

Description

The invention relates to a device for removing and/or limiting oil floating on a water surface or standing on a solid substrate.

Various procedures and accident control measures are available for the removal of oil spills, e.g. after tanker accidents.

ft·· ·· ·· *■· I

Devices have been developed to bind the oil or to prevent the oil from spreading further by limiting the oil surface. The removal of oil floating on the water is particularly problematic when the oil clearance has to be carried out in windy and rough waves. In addition to the use of oil collection vessels, which are able to encircle and skim off oil floating on the water and which can open up their two hull halves using a joint at the stern and absorb the oil in this operating state, the use of oil binding agents such as plastic foams, mixtures of peat and iron powder, straw, paper fibers, etc. is also known to absorb the oil floating on the water and remove it from the water or make it sink using detergents. The use of oil binding agents is carried out in such a way that the oil binding agents are applied or sprayed onto the oil film floating on the water, whereby the oil binding agents are fed onto the oil film from above. In addition to methods for binding the oil, oil barriers consisting of floating hoses or floating partitions are known to prevent the spreading of an oil film floating on the water and to limit the oil surface.

It is also known to use mineral wool to absorb and retain oil from the surface of the water. It is possible to recover the oil from the mineral wool using various mechanical processes.

The present invention is based on the object of creating a device or device with which oil floating on a water surface or standing on a solid surface can be bound and/or limited, whereby the oil absorption capacity is to be improved by increasing the surface area of the oil-absorbing device.

This object is achieved in a device according to the type described above by the features specified in claim 1.

The essential aspect of the invention is the design of the device, according to which it consists of at least one oil-binding agent segment that can be placed on the water surface and is expediently floatable, made of a plate or mat-shaped molded body that is designed in a grid or lattice shape or over the entire surface with perforations and/or in a sandwich-like manner, with at least two plate or mat-shaped molded bodies being connected to one another in a way that lies on top of one another, with the molded bodies being able to be designed over the entire surface or consisting of a combination of full-surface molded bodies with grid or lattice-shaped molded bodies. The individual oil-binding agent segments consist of a pressed, fibrous oil-binding agent made of mineral wool or other suitable artificial or natural fibers (inorganic/organic) with the property that, when pressed into segments, they are able to absorb oil. The oil-binding agent segments can be placed next to one another in a modular manner, so that large-area floating carpets are obtained.

It is also possible to create oil barriers by arranging several oil binding agent segments in rows one behind the other. Glass wool has surprisingly proven to be suitable as an oil binding agent with a high absorption capacity. Even as a single segment, this material in the grid or lattice form shows very good properties in terms of stability and oil absorption capacity, since the grid or lattice form increases the surface area of the oil binding agent segment and improves oil adhesion. The individual oil binding agent segments can be recovered without difficulty. Bound oil can also be easily recovered from the oil binding agent segments using mechanical processes.

The device designed according to the invention with its oil binding agent segments can also be used for removing or binding oil that is on a solid surface or has spread over it or other oil-like liquids such as flammable oils, kerosene, methanol, alcohol, solvents and paint liquids. In addition, the oil binding agent made of mineral wool can be reused, which can be used again after being rolled out or pressed out under low pressure.

The grid or lattice mats and also the sandwich construction are used as individual segments or attached to conventional oil booms, barriers or other structures or placed on the oil or oil slick that has spread on or is standing on a solid surface, whereby roads,

Concrete surfaces, soil, etc. can form the solid base. This means that there are a wide range of possible uses, especially on the water, although it can also be used on the shore/beach or other coastal areas. This covers all technical measures for the delimitation, control and concentration of oil floating on water, so that the oil binding agent segments designed according to the invention can be used as oil barriers, collection barriers, steering or guiding barriers or as pressure barriers.

The oil-binding capacity of the device according to the invention can be further increased by filling the openings, depressions or recesses formed in the molded bodies of the oil-binding agent segments with an oil-binding agent, whereby this oil-binding agent can be impregnated with a biodegradable decomposition agent in the openings of the mineral wool layers of the individual oil-binding agent segments. The particular advantage of using mineral fibers in the device according to the invention
The advantage of this device is its high moisture-repellent effect, whereby the oil absorption capacity is significantly improved by the inventive enlargement of the surface area of the individual oil-binding agent segments. In addition, dipping and rolling
In rough seas, the additional structural design of the oil binding agent segments means that it is braked against an oil barrier. The floating stability is relatively high, so that the device can be used universally.

Advantageous embodiments of the invention are described in
the subclaims.

Embodiments of the invention are explained in more detail below with reference to the drawings.

The device 100 designed according to the invention for removing and/or limiting oil floating on the water surface or standing on a solid surface consists, according to a first embodiment, of a single-layer oil binding agent segment 10, which is formed by a plate- or mat-shaped molded body 11, 111, which is designed in a grid or lattice-like manner or over the entire surface with or without openings 12. (Fig. 1)

The molded body 11 or III of the oil binder segment 10 consists of a pressed, fibrous oil binder made of mineral wool or other suitable artificial and/or natural fibers, whereby glass wool is preferably used, whereby the volume of space for the mineral wool used is expediently around 39 to 41 kg/cubic meter, whereby an absorption capacity of 15 to 20 times its own weight is achieved.

In addition to being used as a full-surface molded body 11, it can also be provided with openings 12 to increase the oil absorption surface (Fig. 1).

Even with a grid-like or lattice-like design of the molded body 111, openings 12 are formed, which also lead to an increase in the surface area of the oil binder segment 10.

The grid or lattice structure of the molded body 111 is obtained by interwoven or connected mineral wool strands 13, whereby these mineral wool strands 13 can be connected to one another in a grid-like manner; preferably, the mineral wool strands 13 are interwoven in the manner of a plain weave (Fig. 2).

The arrangement of mineral wool strands 13 arranged in rows at intervals next to one another is also possible for the formation of the shaped body 111 (Fig. 3).

In all these embodiments, the molded body 111 has openings 12.

According to a further embodiment according to Fig. 4, 5, 6 and 7, the oil binding agent segment 110 is multi-layered, i.e. sandwich-like, with the individual layers being formed by full-surface molded bodies 11 and/or molded bodies 111 that are designed in a grid or lattice-like manner. Fig. 4 shows a two-layered oil binding agent segment 110 that consists of two mat-shaped molded bodies, of which the molded body 11 is full-surface and the molded body 111 arranged above it is designed in a grid or lattice-like manner and has openings 12. Both

12

Molded bodies 11, 111 are connected to one another mechanically or by means of an adhesive bond. In this embodiment and in the following embodiments, there is no restriction to a two-layer design. The oil binding agent segment 110 can also be designed in multiple layers.

The oil binding agent segment 110 according to Fig. 5 is formed by two grid-shaped or lattice-shaped molded bodies 111, which are arranged one above the other in such a way that their openings 12, 12' are offset from one another. The oil binding agent segment 111 according to Fig. 6 is designed in the same way as the oil binding agent segment 110 according to Fig. 5, but the openings 12, 12' are filled with an oil binding agent 30. This oil binding agent 30 in the openings 12, 12' of the mineral wool layers 16, 16' of the molded bodies 111 is impregnated with a biodegradable decomposition agent. The oil binding agent segment 110 according to Fig. 7 is designed in a similar way to the oil binding agent segment 110 in Fig. 4, but the openings 12 in the molded body 111 are also filled with an oil binding agent 30. As Fig. 8 shows, an oil binding agent segment can also be formed, for example, from three mat-shaped molded bodies 11, 111, with the molded body 111 in its grid-like or lattice-like design being arranged between two molded bodies 11 formed over the entire surface.

Each oil binder segment 10, 110 consists of

artificial, compressed fibers of a mineral wool, the fibers having a diameter of less than or more than 1 /im, preferably an average diameter of 3 to 6 μια and a fiber length of several cm. The fibers, such as mineral wool, of the molded bodies 11, 111 are equipped with binding and impregnating agents and oils for firmly binding the fibers into the molded bodies of the oil binding agent segments 10, 110. Equipping the mineral wool with binding and impregnating agents and/or oils causes the fibers to be firmly bound into the product, thereby achieving a high water-repellent effect that improves oil absorption. Glass wool is used, the glass fibers being provided with aliphatic mineral oils and/or methylpolysiloxanols, with or without the addition of other synthetic resins.

A fully formed molded body 11 with openings 12 is shown as a further embodiment in Fig. 22. Fig. 23 shows a molded body 111 which is designed in the form of a grid or lattice.

The oil binding agent segment 10, 110, which is constructed in a grid or lattice-like manner, over the entire surface or in a sandwich-like manner, is used as a single floating construction element or is attached to conventional oil booms, barriers or other structures. It is also possible to combine several oil binding agent segments consisting of the molded body 11, 111 to form large-area carpets, in particular floating carpets 20. (Fig. 18).

The oil binding agent segment 10, 110 or its molded body 11, 111 can be covered with a net-like covering 14.

• · · · · ♦ ft

i.e. the oil binding agent segments 10, 110 are woven into a net-like covering 14 in order to be able to use the mineral wool from which the molded bodies 11, 111 are made in a firmly enclosed manner. (Fig. 1). It is also possible to enclose the oil binding agent segment 10, 110 with or without a net-like covering 14 in a plastic film 114, whereby vacuum packaging with a plastic film is also possible.

According to a further embodiment according to Fig. 9, at least one oil-binding agent segment 10, 110 is arranged on one of the two sides of a floating body 40 that is tubular or box-like or consists of a blown-out floating hose and is connected to a vertically extending apron-like partition wall 41 that is connected to a ballast body 42 at its free end lying in the water. Such a design leads to a device 100 that, in addition to binding oil, also enables oil floating on the water surface to be limited and can therefore be used as an oil-binding oil barrier at the same time. Depending on the length of the oil barrier to be formed, several floating bodies 40, 40'' with the corresponding number of oil-binding agent segments 10, 111 are then arranged one behind the other. (Fig. 13).

To increase the oil absorption capacity, the floating body 40 can also carry an oil binding agent segment 10, 110 on each of its two sides, as shown in Fig. 10.

In the embodiment shown in Fig. 11, at least two floating bodies 40, 40' are arranged next to one another, with each floating body 40, 40' carrying an oil-binding agent segment 10, 110 on both sides. The two floating bodies 40, 40' are connected via their opposite oil-binding agent segments. The connection is indicated at 45. (Fig. 11).

In addition to a plate-shaped design of the oil binding agent segments 10, 110, it is also possible to use oil binding agent segments 210, which consist of a cylindrical molded body 211 (Fig. 12). The floating body 40, 40' carries an oil binding agent segment 10, 110, 210 on one of its two sides or on both sides, the oil binding agent segment having a length corresponding to the length of the floating body 40, 40' or 40''. The oil binding agent segments used here can be single-layered or sandwich-like and consist of full-surface molded bodies 11 and/or grid-like or lattice-like molded bodies 111.

As an oil barrier and oil absorption device, several oil binding agent segments 110 can also be arranged one behind the other in a sandwich form according to Fig. 14 and connected to one another by means of a toothing indicated at 50. Here too, sandwich-like oil binding agent segments 110 can be used, in which at least two grid-like or lattice-like shaped bodies 111 are arranged one above the other.

are arranged horizontally. The openings 12 then formed in these shaped bodies 111 are filled with an oil binding agent 30. (Fig. 15).

The technical measures for the delimitation, control and concentration of oil floating on water bodies are shown in Figs. 16A, 16B, 16C and 16D. Fig. 16A shows a general oil barrier, Fig. 16B a collective barrier, Fig. 16C a steering or guide barrier and Fig. 16D a trough barrier, whereby in Figs. 16A, 16B, 16C and 16D the barrier formed by means of the device 100 according to the invention is marked with SP.

Several oil binding agent segments 10, 110 combined to form a floating carpet 20 are provided with a number of buoys 60, as shown in Fig. 17. The floating carpet 20 according to Fig. 18 is provided with additional buoyancy bodies 61 and with connections 62 for tow lines 63. The towing direction is in the direction of arrow X. A floating carpet 20 formed from the oil binding agent segments 10 or 111 is towed to the site of use by tugs or other floating vehicles. In this way, it is possible to bring the device 100 designed according to the invention in the form of floating carpets or as a prepared oil barrier to the site of use without great effort.

Fig. 19 shows several floating bodies 40, 40'' arranged one behind the other in a row and connected to one another, each floating body being made of the same material as the oil binding agent segments 10, 110, 210.

The floating bodies 40, 40 ' are not exclusively usable in connection with sandwich-like oil binding agent segments 110. According to Fig. 20 and 21, it is also possible to provide the floating bodies 40, 40' on one or both sides with oil binding agent segments IO which are designed in a single layer, the shaped bodies 111 forming the oil binding agent segments IO being designed in a grid or lattice-like manner with the formation of openings 12.

Each oil binding agent segment 10, 110 has a square, rectangular or other geometric shape, but the oil binding agent segment 10, 110 should have at least two straight edges in order to connect several oil binding agent segments to form large-area oil barriers or floating carpets. Several oil binding agent segments 10, 110 can be assembled in a large-area modular manner, with the individual oil binding agent segments being connected to one another using known connecting means that are mechanical in nature, but clamping, snap-in or Velcro connections can also be used.

According to a further embodiment, one or more oil binding agent segments 10 or 100 are assembled in a modular manner, wherein the buoyancy body 61 or 40 consists of a disposable material, such as a tube made of a plastic film, preferably a polyethylene plastic film.
