    Normal boats may have difficulty navigating or the required approaches and the like may not be sufficiently sufficient to transport boats or the like to the spill site.
    In connection with spills of environmentally hazardous liquids and the like, there are also problems with the environmentally hazardous liquid and any absorbent used after they have been taken up usually having to be destroyed. Environmentally hazardous liquids, with associated absorbent, are usually destroyed by combustion or the like. During the combustion of the environmentally hazardous liquids, as well as any absorbents used, there may be problems if these contain high levels of water. In order for the destruction of the absorbed waste liquids to be as efficient and environmentally friendly as possible, there is therefore a great need for absorbed waste liquids, as well as any absorbed absorbers, to contain as little water (has as high a dry matter content) as possible. OBJECTS OF THE PRESENT INVENTION The main object of the present invention is to provide a substantially improved system for collecting liquid such as, for example, oils, chemicals or the like from water surfaces. Another object of the present invention is to create a system which is less labor intensive than previously known systems. It is a further object of the present invention to create a system which contributes to fewer work injuries occurring when absorbing liquid from water surfaces. A still further object of the present invention is to create a more efficient and environmentally friendly after-treatment or destruction of absorbed waste liquids.

Note that the figures are schematic and that details can thus be omitted in them.

    Detailed Description of the Invention Referring to the gurus, there is shown a system 1 for transferring and collecting contaminants such as various liquids or the like from a surface 2 in accordance with the present patent application. The system 1 is preferably used to collect contaminants in the form of environmentally hazardous liquids such as oils, diesel, chemicals and similar liquids which have grazed on the surface 2 of a liquid collection 3. The liquid collection 3 preferably consists of a water surface or the like.
    The system 1 comprises at least one pollution collecting device 4 and at least one pollution removing device 5. In the exemplary embodiment, the pollution collecting device 4 comprises a surface V-shaped structure 6 which is intended to direct (direct) the pollutants towards the pollution moving device 5.
    The V-shaped structure 6 comprises at least a first fl-surface part 7 and at least a second fl-surface part 8 which at their one ends are hingedly connected to each other. The pollution collecting device 4 also comprises at least one interconnecting unit 9 which also functions as a locking device with which the first part 7 and the second part 8 are temporarily locked relative to each other in a fully or partially unfolded position. It is conceivable that the angle of the V-shape is fixedly arranged or is arranged to be adjustable within an angular range.
    In the exemplary embodiment, the contaminant dispensing device 5 comprises at least one suction device 10. The suction device 10 preferably comprises at least one negative pressure generating device 11 which creates a negative pressure in at least one suction line 12 which is connected to the pollution collecting device 5. The suction device 10 may comprise a negative pressure generating device 1 by an industrial vacuum cleaner or arm suitable for the purpose of creating a negative pressure. In alternative embodiments, the negative pressure generating device 11 may be a negative pressure generating device 11 which is integrated in a suction truck or integrated in another armored vehicle or vehicle. The suction device 10 can also be constituted by another pressure-creating device suitable for the purpose.
    The suction line 12 comprises at least one hose, a pipe or a combination of hose and pipes. In the exemplary embodiment, the suction line comprises at least one hose from the negative pressure generating device which connects to at least one suction pipe (pipe) 13 (nozzle, hose or the like) which is connected via at least one bracket 14 to the pollution collecting device 4.
    In the exemplary embodiment, the suction tube 13 is placed in a substantially vertical direction relative to the liquid surface. However, it is conceivable that the suction tube has a different direction towards the liquid surface than substantially vertical.
    In a preferred embodiment of the present patent application, the position of the suction tube (suction member) 13 is arranged to be adjustable relative to the surface of the liquid. The adjustability of the position (height) of the suction pipe 13 in relation to the surface of the liquid (water surface) can be achieved with a number of different techniques. In the exemplary embodiment, the height of the suction tube 13 is adjusted with at least one expandable body 15 such as at least one pressurizable body 16. In the preferred embodiment, the pressurization of the pressurizable body 16 takes place via compressed air. In alternative embodiments, it is conceivable that the pressurization of the pressurizable body takes place with the aid of a pressurized liquid. It is further conceivable that the height of the suction tube is adjusted with another adjusting device suitable for the purpose previously known.
    The present system 1 is preferably intended to be used in a method (method) where an oil absorbent 17 from above is applied to the layer of contaminant (oil) on the surface of the liquid. The oil absorbent 17 may be a number of different means which substantially surface on the surface of a liquid. In the preferred embodiment of the present patent application, the oil absorbent 17 is comprised of an oil absorbent which substantially contains bark or treated peat.
    After the oil absorbent (bark) 17 is applied to the oil layer, the oil absorbent (bark) absorbs all or part of the oil. By means of the contaminant collecting device 4, the oil absorbent is then collected with absorbed oil and sucked up by the suction pipe 13 of the contaminating device 5.
    Unique to the present process is that in an alternative embodiment this comprises a sub-process where the oil absorber is also applied to the oil layer from the underside of the oil layer. This is preferably done with an absorbent supply device 18 which is connected to the pollution collecting device 4. The absorbent supply device 18 supplies absorbent 17 via at least one pipe 19, hose, nozzle or the like, to a certain depth below the water surface 2 and below the layer of oil (alternatively other pollution).
    In the preferred embodiment, the bark (absorbent) is lowered below the oil layer via a flow of water through a pipe 19 which opens at a certain depth below the surface. The flow of water and bark (the absorbent) can be effected by a submersible pump 20 which, for example, is provided with at least one floating collar 21 or the like and is placed in the liquid (the water). From the pump 20 a line 22, hose, pipe or the like runs to at least one mixing unit 23 where the absorbent (bark) is supplied with the flow of water.
    Because the absorbent 17 substantially fl surfaces, the oil absorbent applied below the surface will fl surface up against the oil eskite (the contaminant) and the oil absorber previously applied from above. Through the process, the oil layer will be entrapped in the oil absorbers applied from above and below. By adding the oil absorber both from above and below, the collecting effect will be significantly improved (increased). Furthermore, the dry content of the collected absorbent will increase. Which means that a significantly smaller proportion of water is carried to the filter.
    In the present method, the applied oil absorbent and the absorbed oil (the contaminant) are collected with the contaminant collecting device 4 and moved towards the suction pipe 13 of the contaminating device 5.
    Because the height of the mouth of the suction pipe 13 can be adjusted in height, in relation to the layer of absorbent and the water surface, the absorbing effect of the device can be adjusted. Depending on the thickness of the oil layer and the oil absorber, the position of the mouth of the suction pipe 13 can be adjusted in the vertical direction. By adjusting the height of the suction tube 13 (above the layer of absorbent and the water surface), the absorbent effect of the absorbent can be substantially optimized so that as small an amount of water, located below the layer of absorbent and contaminant (oil), as possible is absorbed by the suction tube.
    The oil absorber absorbed via the suction pipe, with absorbed oil (contamination) and a small amount of water, is passed via the suction line and the negative pressure generating device 11 to at least one container 24, vessel or the like. The container 24 is preferably placed on a boat 25, adapted raft, ship, barge or the like. The container can also be located on land or be integrated in a vehicle. The V-shaped structure 6 is connected to the boat with the required ropes, struts or other structures suitable for the purpose.
    In the exemplary embodiment, the container consists of a dish to which the negative pressure-creating device is connected. In the exemplary embodiment shown in Figures 1 and 4, the container 24 comprises at its upper end at least one lid 26. The lid 23 may be temporarily lockable to the vessel 24 via, for example, a so-called ring lock or the like. In the exemplary embodiment, the negative pressure generating device is connected to the upper part of the vessel 24, as preferably to the lid 26. In Fig. 1, only a part of the suction line 12 is shown.
    The container 24 comprises, in the exemplary embodiment, at least one separator with which the oil absorber is separated from a smaller volume of water which accompanies the absorbent to the container 24 and the separator. In the exemplary embodiment, the separator consists of at least one filter, which allows a separation of the water from the oil absorber (with associated contaminant, oil). The filter may, for example, consist of at least one filter bag, placed in the container, to which the absorbed oil absorber with associated oil and water is fed. The oil absorber remains in the filter bag while the absorbed water flows through the filter bag and collects on the bottom of the container. From the bottom of the container, the water flows with self-pressure, or is pumped with an integrated submersible pump, back to the oil-damaged water surface in front of the suction pipe 13. The water can be pumped through at least one pipe, hose or similar. Any remaining oil in the water or the like can thereby be absorbed by the oil-absorbent material and therein be sucked up again by the suction pipe 13 (and then fed to the container 24 with associated separator). The method causes the system 1 to become of a partially closed nature during the cleaning work. In alternative procedures, the water from the container 24 may be transferred to one or more containers (not shown in urer gures) from which the water is transferred to the appropriate disposal of environmentally hazardous liquids.
    At the beginning and end of the decontamination work, the absorbent is filled directly into the filter bag to optimize the uptake of contaminants.
    In the preferred embodiment, the system comprises at least two containers 24. The first bag of the first container is first filled with absorbent and absorbed contaminant (oil). When the first bag of the first container is full, the lid 26 is moved from the first container 23 to the second container 24, after which the filling of the second bag of the second container can begin. When the filling of the second container's bag starts, the fully or partially filled bag in the first container can be replaced by an empty bag. As the äcklter sacks in the respective containers are filled in, these are transferred to a load carrier for the purpose for further transport for destruction or composting.
    Figure 1 also shows how the system, if necessary, includes at least one unit 27 for generating, or supplying, electrical energy to the electrical components of the system. Figure 1 also shows how the system comprises at least one unit 28 for supplying compressed air to the system, such as for example to the expandable body. The unit 28 may be a compressor with or without at least one pressure tank.
    Alternatively, the absorbed absorbent (bark) with absorbed contaminant (oil) can be taken directly to a package, tank or similar for further transport for destruction. All depending on the water content and consistency of the collected oil.
    At least one guide member 29 or the like can be connected to the first part 7 of the V-shaped structure and the second part 8. The task of the guide means 29 is to guide the absorbent means 17, with associated absorbed liquid, in the direction of the suction pipe 13. The guide means 29 can be constituted by a straight hose such as a fire hose or the like.
    With reference to Figure 5 shows how the suction pipe 13 in alternative embodiments can be replaced by a pump 30 or the like.
    In alternative embodiments, as shown, for example, in Figure 6, it is conceivable that the suction tube 13 may be used by a person walking along the beach and sucking up scattered oil absorbing material (with absorbed oil). The absorbed oil absorbs the material and carries it via the suction line to the container and the filter unit. In the filter unit, the oil-absorbing material is separated from any accompanying water.
    In the detailed description of the present invention, construction details and sub-procedures may be out of the art which will be apparent to one skilled in the art to which the device relates. Such obvious construction details and sub-procedures are included to the extent required for a proper function to be obtained for the present device. For example, it is assumed that power lines, any hoses for compressed air, fasteners, control systems with your details and components are included to the required extent. Although some preferred embodiments have been shown in more detail, variations and modifications of the device may be apparent to those skilled in the art to which this invention relates. All such modifications and variations are considered to fall within the scope of the appended claims.
    Advantages of the Invention With the present invention, a number of advantages are achieved. The most obvious is that a more efficient system, than previously known systems, for collecting environmentally hazardous liquids from, for example, a liquid surface such as a water surface is obtained.
