Abstract
A device (1) for cleaning a liquid (3) contaminated with oil, comprising a filling (7) made of a material that absorbs the oil (2), which filling is located inside a container (4) and is arranged between an inlet and an outlet (5, 6) of the container (4). According to the invention, the absorption property and handling of the filling (7) is increased by virtue of the fact that the filling is formed by a package-type tangle of keratin structures (8) that are randomly arranged and stochastically distributed in all three dimensions, which in the operating state of the device (1), comprise a closed container edge (9) between the inlet and the outlet (5, 6), and rest thereon in a liquid-tight manner.
Claims8
A device for cleaning a liquid contaminated with oil, comprising a container having an inlet for a contaminated liquid and an outlet for a cleaned liquid and at least one valve disposed in the inlet or outlet, wherein the container contains a packing of a material that can absorb the oil, through which material the contaminated liquid can flow to leave the contaminants behind, the packing comprises a package-like tangle of keratin structures that are randomly distributed in all three dimensions, the keratin structures are enclosed by a closed container edge between the inlet and the outlet and fit against it in a liquid-tight way the package-like tangle of keratin structures is essentially uniformly compacted along the path of the liquid between the inlet and outlet, wherein the compaction is such that the keratin structures absorb at least 6.5 times their own weight of oil from the fluid before saturation of the keratin structures with oil occurs, the packing is formed by the first absorption unit within a reception space of the container, wherein the first absorption unit present in the reception space can be replaced automatically with a second absorption unit in the reception space of the container by an exchange device assigned to the container, wherein the replacement takes place when the first absorption unit exhibits a predetermined degree of oil saturation, wherein the degree of saturation of the absorption unit is determined automatically by an optical recognition device attached to the container or to the outlet, wherein the recognition device is connected to a programmable logic controller, which addresses the exchange device through a respective connection for the automated exchange of absorption units and optionally stops the continuous in-flow or out-flow of liquid by addressing the respective valve in the inlet or outlet, wherein the respective first absorption unit is automatically supplied to a collection point through a transport device after the exchange has taken place.
