Abstract
Description
Die Erfindung betrifft ein Gerät zur seegangsunab hängigen Aufnahme von schwimmenden Substanzen (7) auf Gewässern und ist anwendbar sowohl beim Neubau als auch bei der Nachrüstung und Umrüstung beste hender Bekämpfungssysteme.The invention relates to a device for seegangsunab dependent recording of floating substances ( 7 ) on water and is applicable both in new construction and in the retrofitting and retrofitting best existing control systems.
Der Bedarf der Abschöpfung von Flüssigkeiten oder kleinen schwimmenden Elementen tritt auf, wenn Sub stanzen an oder nahe der Oberfläche schwimmend, aus dem Wasser entfernt werden sollen. Beispiele dafür sind Havarien von Schiffen, Leckage aus Behältnis sen oder übermäßiges Algenwachstum. Die bestehenden Systeme arbeiten bei bewegter Wasseroberfläche nur sehr eingeschränkt und sind ab einer bestimmten Wellenhöhe nicht mehr einsetzbar. Bei bestehenden Systemen wird die Abschöpfung an der freien, beweg ten Oberfläche durchgeführt, was zu unerwünschten Strömungs- und Mischungsprozessen führt und damit die Wirkungsweise einschränkt.The need for skimming liquids or small floating elements occurs when sub punch out floating at or near the surface to be removed from the water. Examples of this are ship accidents, leakage from containers or excessive algae growth. The remaining Systems only work when the water surface is moving very limited and are from a certain Wave height can no longer be used. With existing Systems will skim off the free, moving th surface performed, leading to undesirable Flow and mixing processes leads and with it limits the mode of action.
Ein Gerät nach den in den Patentansprüchen spezifi zierten Eigenschaften ist dagegen auch bei durch Wellen oder Strömung bewegter Wasseroberfläche ein setzbar. Es beruht auf dem Prinzip, daß die kontaminierte Wasseroberfläche von dem Gerät befah ren wird, wobei die seegangsbewegte Oberflächenströmung unter einen eintauchenden Kör per (1) gedrückt wird und an der Unterseite (4) des Geräts entlang fließt, bis es an geeigneter Stelle durch hydrodynamisch optimierte Einläufe (3) in das Innere des Geräts gepumpt wird. Durch die so ent standene Aufteilung (8) der Strömung können die nun nahe der Unterseite (4) schwimmenden Substanzen in hoher Konzentration aufgenommen werden und einer weiteren nachgeschalteten Separation (6) zugeführt werden.On the other hand, a device according to the properties specified in the claims can also be used when the water surface is moved by waves or currents. It is based on the principle that the contaminated water surface is moved by the device, the sea-moving surface flow is pressed under an immersed body by ( 1 ) and flows along the underside ( 4 ) of the device until it is hydrodynamically located at a suitable point optimized inlets ( 3 ) is pumped into the interior of the device. Due to the resulting division ( 8 ) of the flow, the substances now floating near the underside ( 4 ) can be taken up in high concentration and fed to a further downstream separation ( 6 ).
Bei bisherigen Verfahren wird versucht, die zu ent fernende Flüssigkeitsschicht durch die geometrische Formgebung oder Staudruckeffekte von der Oberfläche zu separieren. Diese Erfindung hingegen verwendet aktive Abpumpvorrichtungen, die die für diesen Ab saugprozeß so wichtige Grenzschichtstabilität an der Geräteunterseite (4) erzeugt. Für den Absaug prozeß störende Strömungsablösung sowie daraus resultierende Verwirbelungen und Mischungsprozesse werden somit unterdrückt.In previous methods, attempts have been made to separate the liquid layer to be removed from the surface by means of the geometric shape or dynamic pressure effects. This invention, on the other hand, uses active pumping devices which produce the boundary layer stability on the underside ( 4 ), which is so important for this suction process. Flow separation disruptive to the suction process and the resulting turbulence and mixing processes are thus suppressed.
Das Gerät kann einzeln oder als integrierter Be standteil einer größeren Struktur gebaut werden. Denkbar ist hier beispielsweise die Integration des Gerätes zwischen den Einzelrümpfen eines Katamaran schiffes (5) oder die seitliche Anbringung an der Bordwand von Schiffen.The device can be built individually or as an integral part of a larger structure. It is conceivable here, for example, to integrate the device between the individual hulls of a catamaran ship ( 5 ) or to mount it on the side of ships.
Das Gerät kann sowohl mit eigenem Antrieb ausge stattet sein, als auch geschleppt oder geschoben werden. Für den Fall, daß das Gerät mit eigenem An trieb versehen ist, kann das abgeschöpfte und gereinigte Wasser (10) in einem Wasserstrahlantrieb zum Antrieb oder zur Unterstützung des Antriebs verwendet werden.The device can be equipped with its own drive, as well as towed or pushed. In the event that the device is provided with its own drive, the skimmed and purified water ( 10 ) can be used in a water jet drive to drive or to support the drive.
Um den Anteil der verunreinigten Wassermenge am ge samten Abschöpfvolumen zu maximieren, können geeignete Steuermaßnahmen zur gezielten Regelung des Volumenstroms installiert werden. Dies kann durch Einläufe mit variabler Öffnungsfläche und -ausrichtung sowie durch Regelung der Pumpenleistung realisiert werden. Die Steuerung sowohl der Öff nungsgeometrie als auch der Pumpenleistung kann dabei durch Verwendung einer geeigneten Sensorik automatisiert werden.To the proportion of the contaminated amount of water on ge to maximize the entire skimming volume appropriate tax measures for targeted regulation of the volume flow can be installed. This can through inlets with variable opening area and -alignment and by regulating the pump output will be realized. The control of both the public geometry and pump performance by using suitable sensors be automated.
Der vordere Bereich der Unterseite kann derart aus geführt sein, daß eine Verwirbelung der Oberflächenströmung reduziert oder gezielt bein flußt wird. Dies kann einerseits durch die Wahl eines Materials mit diskret oder kontinuierlich veränderlicher Steifigkeit, als auch durch eine Ka nalstruktur in Längsrichtung realisiert werden.The front area of the underside can look like this be led to a turbulence of Surface flow reduced or targeted is flowing. On the one hand, this can be done by choosing of a material with discrete or continuous variable stiffness, as well as by a Ka Longitudinal structure can be realized.
