Description

Absaugvorrichtung und Absaugverfahren  Suction device and suction method
Die vorliegende Erfindung betrifft eine Vorrichtung und ein Verfahren zum Absaugen von Flüssigkeiten und/oder Suspensionen unterhalb einer Wasseroberfläche mit einer endseitig angeordneten Glocke und einem hieran angeordneten Absaugrohr. The present invention relates to a device and a method for aspirating liquids and / or suspensions below a water surface with a bell arranged at the end and a suction tube arranged thereon.
In der jüngsten Vergangenheit hat die Havarie der Bohrinsel„Deepwater Horizon" im Golf von Mexiko Schlagzeilen gemacht. Die Problematik einer solchen Havarie liegt insbesondere in den immensen Ölmengen, die in die betroffenen Gewässer ausströmen, wo sie oberhalb, aber auch unterhalb der Wasseroberfläche erhebliche Schäden der Flora und Fauna verursachen. Dabei bildet das Öl ausgedehnte Teppiche, die sich teilweise über etliche Kilometer Länge erstrecken können. In Küstennähe lagert sich das Öl an Korallen oder anderen küstenbildenden Formationen an, wo bereits jetzt die Zerstörung der Tier- und Pflanzenwelt zu erkennen ist. In the recent past, the sinking of the Deepwater Horizon oil rig in the Gulf of Mexico has made headlines, with the problem of such an accident being due in particular to the immense quantities of oil that flow into the affected waters, causing significant damage both above and below the water surface It produces extensive carpets, some of which can extend over several kilometers in length, and accumulates near coral or other coastal formations near the coast, where the destruction of flora and fauna is already evident ,
Derzeit mangelt es immer noch an einer Technik, mit der möglichst rasch eine große Menge von Öl, anderer schädlicher Suspensionen oder Gemische dem Wasser entzogen werden können. Insbesondere bei einer Ölquelle in großen Tiefen bereitet das Absaugen des ausströmenden Öls große Probleme, da erhebliche Druckunterschiede überwunden werden müssen und die aufbringbare Saugkraft von der Oberfläche aus an physikalische Grenzen stößt. Demgegenüber ist es aus technischen Gründen erheblich einfacher hohe Drücke zu erzeugen, die ohne Probleme höher sein können als der in tiefen Meeresregionen herrschende Druck. At present, there is still a lack of technology that can remove as quickly as possible a large amount of oil, other harmful suspensions or mixtures from the water. Especially with an oil well at great depths, the suction of the escaping oil causes great problems, since significant pressure differences must be overcome and the applied suction force from the surface reaches physical limits. In contrast, it is much easier to produce high pressures for technical reasons, which can be higher without problems than the pressure prevailing in deep ocean regions pressure.
Es ist Aufgabe der vorliegenden Erfindung eine Vorrichtung und ein Verfahren zu schaffen, mit der schädliche Flüssigkeiten, Suspensionen oder andere Gemische unterhalb der Wasseroberfläche abgesaugt und damit dem Gewässer entnommen werden können. It is an object of the present invention to provide a device and a method, are sucked with the harmful liquids, suspensions or other mixtures below the water surface and thus can be removed from the water.
Diese Aufgabe wird durch die Vorrichtung nach Anspruch 1 und das Verfahren nach Anspruch 8 gelöst. Die Vorrichtung besitzt erfindungsgemäß mindestens eine Pressluftzufuhr, die im unteren Bereich der Vorrichtung in das Saugrohr oder in die This object is achieved by the device according to claim 1 and the method according to claim 8. The device according to the invention has at least one compressed air supply, in the lower part of the device in the suction pipe or in the
BESTÄTIGUNGSKOPIE Glocke mündet. In dem Saugrohr steigt die einströmende Pressluft nach oben auf, wodurch eine Sogwirkung entsteht, aufgrund der das Öl bzw. das abzusaugende Flüssigkeitsgemisch (als Emulsion oder Suspension) nach oben transportiert wird. Hiermit können in kurzer Zeit große Mengen an Flüssigkeit, Emulsionen oder Suspensionen, wie beispielsweise Öl oder andere Chemikalien, dem Wasser entzogen werden. Zudem ergibt sich aufgrund der sehr turbulenten und damit schnellen Strömung innerhalb des Saugrohrs nicht das Problem, dass sich beim Absaugen in großen Tiefen Eiskristalle in der Vorrichtung bilden, die das Absaugen wirksam verhindern, wie es beispielsweise bei Absaugversuchen im Rahmen der oben genannten Havarie in einer Tiefe von ca. 1.500 m passiert ist. Die Vorrichtung ist insbesondere auch in flachen und küstennahen Gewässern sowie in Tiefseebereichen einsetzbar. CONFIRMATION COPY Bell opens. In the suction pipe, the incoming compressed air rises upwards, whereby a suction effect arises, due to which the oil or the liquid mixture to be sucked (as an emulsion or suspension) is transported upwards. This can be removed from the water in a short time large amounts of liquid, emulsions or suspensions, such as oil or other chemicals. In addition, due to the very turbulent and thus fast flow within the suction pipe does not present the problem that form when sucking at great depths ice crystals in the device, which effectively prevent the suction, as for example in extraction tests in the above mentioned accident in a Depth of about 1,500 m has happened. The device can be used in particular in shallow and coastal waters as well as in deep-sea areas.
Weitere bevorzugte Ausgestaltungen sind im Folgenden wie in den Unteransprüchen beschrieben. Further preferred embodiments are described below as in the subclaims.
Nach einer ersten bevorzugten Weiterbildung der Vorrichtung ist vorgesehen, dass die Press luftzufuhr ein Schlauch ist, der ein düsenförmiges Endstück besitzt, dass so in die Vorrichtung mündet, dass die Pressluft nach oben gerichtet in die Vorrichtung gepresst wird. Die Strömungswirkung entsteht dadurch, dass die eingeblasene Luft innerhalb des Rohres nach oben steigt. Dabei ist der Fördereffekt umso größer, je schneller die Luft nach oben steigt. Somit wird durch die bevorzugte Ausbildung eine größere Sogwirkung erzielt. According to a first preferred embodiment of the device is provided that the compressed air supply is a hose having a nozzle-shaped end that opens into the device so that the compressed air is directed upwards pressed into the device. The flow effect arises from the fact that the injected air rises inside the tube to the top. The transport effect is greater, the faster the air rises to the top. Thus, a greater suction effect is achieved by the preferred embodiment.
Um die Sogwirkung noch weiter zu erhöhen, ist nach einer weiteren Ausgestaltung vorgesehen, dass die Pressluftzufuhr mehrere düsenförmige Endstücke aufweist, die in radialer Richtung in die Vorrichtung beabstandet einmünden. Mit einer derartigen Ringdüse wird nicht nur die Sogwirkung verstärkt, sondern es entsteht zudem eine Strömung, innerhalb der sich keine Eiskristalle bilden und die das Verklumpen des Öls in der Saugleitung wirksam verhindert. Vorzugsweise sind mehrere Pressluftzuführungen vorgesehen, die in axialer Richtung entlang des Saugrohrs beabstandet einmünden, was zu einer gleichmäßigen Sogwtrkung entlang des Saugrohrs führt. Je nach Tiefe der abzusaugenden Flüssigkeit ist die Anzahl der Press luftzuführungen anzupassen. In order to increase the suction effect even further, it is provided according to a further embodiment that the compressed air supply has a plurality of nozzle-shaped end pieces, which open in the radial direction in the device spaced. With such a ring nozzle, not only the suction effect is enhanced, but it also creates a flow within which no ice crystals form and effectively prevents the clumping of the oil in the suction line. Preferably, a plurality of compressed air supply lines are provided, which open in the axial direction along the suction tube spaced, resulting in a uniform Sogwtrkung along the suction pipe. ever according to the depth of the liquid to be sucked, the number of press air feeds must be adjusted.
Nach einer bevorzugten Ausführungsform der vorliegenden Erfindung münden die Pressluftzuführungen in im Wesentlichen äquidistanten Abständen, beispielsweise von 50 m bis 100 m, entlang der gesamten Länge und in axialer Richtung des Saugrohres ein. Die gewählten Abstände hängen im Wesentlichen von der Wassertiefe, aus der die Absaugung stattfinden soll, und von der zur Verfügung stehenden Anzahl von Kompressoren ab. According to a preferred embodiment of the present invention, the compressed air feeds open at substantially equidistant intervals, for example from 50 m to 100 m, along the entire length and in the axial direction of the suction pipe. The selected distances depend essentially on the depth of water from which the suction is to take place and on the number of compressors available.
Zwar wird die größte Sogwirkung durch die Pressluftzuführungen verursacht, die im unteren Bereich des Saugrohres einmünden, allerdings wird durch die besondere Ausbildung ein schnelles und auch zuverlässiges Anfahren der Vorrichtung auch in großen Tiefen ermöglicht. Die Sogwirkung entsteht nämlich durch die in dem Saugrohr aufsteigende Pressluft. Hierzu muss der hydrostatische Druck zunächst überwunden werden, bevor die Pressluft in das Saugrohr gelangt. Durch die bevorzugte äquidistante Anordnung können die Pressluftzuführungen in Abhängigkeit von der Tiefe, in der sie in das Saugrohr einmünden, angesteuert werden, so dass erfindungsgemäß die Pressluftzuführungen sukzessive von oben nach unten mit Pressluft beaufschlagt werden können. Bei der obersten Pressluftzufuhr herrscht aufgrund der vergleichsweise geringen Tiefe ein geringerer hydrostatischer Druck, der der Pressluftzufuhr entgegensteht. Sobald Pressluft durch die oberste Pressluftzufuhr in das Saugrohr geleitet wird, entsteht bereits eine vergleichsweise geringe Sogwirkung entlang des gesamten Saugrohres. Hierdurch reduziert sich allerdings gleichzeitig der hydrostatische Druck an den übrigen Pressluftzuführungen, so dass bei sukzessivem Beaufschlagen der Pressluftzuführungen der an den Pressluftzuführungen herrschende hydrostatische Druck verringert werden kann, der der Pressluftzufuhr entgegenwirkt. Hierdurch wird sogar in großen Tiefen eine hinreichende Versorgung mit Pressluft ermöglicht. Although the greatest suction effect caused by the compressed air supply, which open in the lower part of the suction tube, however, is made possible by the special training a fast and reliable start-up of the device, even at great depths. The suction effect is created by the rising in the suction pipe compressed air. For this purpose, the hydrostatic pressure must first be overcome before the compressed air enters the intake manifold. Due to the preferred equidistant arrangement, the compressed air feeds can be controlled as a function of the depth at which they open into the suction pipe, so that according to the invention the compressed air feeds can be successively supplied with compressed air from top to bottom. In the top compressed air supply prevails due to the relatively small depth, a lower hydrostatic pressure, which precludes the supply of compressed air. As soon as compressed air is directed into the intake manifold through the highest compressed air supply, a comparatively low suction effect is already created along the entire intake manifold. At the same time, however, this reduces the hydrostatic pressure at the remaining compressed air supply lines, so that upon successive application of the compressed air supply lines, the hydrostatic pressure prevailing at the compressed air supply lines can be reduced, which counteracts the compressed air supply. This allows a sufficient supply of compressed air even at great depths.
Wie bereits erwähnt, muss der angelegte Pressluftdruck höher als der hydrostatische Druck sein, der in der Wassertiefe herrscht, wo die Pressluft eingelassen wird, vor- zugsweise ist der Pressluftdruck 105 bis 3 x 105 Pa höher als der jeweilige hydrostatische Druck. Die Abstände der Pressluftzuführungen können auch ungleich sein, beispielsweise kann die erste Pressluftzufuhr in 25 m, die zweite in 50 m, die Dritte in 100 m, die vierte in 500 m, die Fünfte in 1.000 m Wassertiefe und gegebenenfalls jede weitere in einem Abstand von 1.000 m zur vorhergehenden Pressluftzufuhr angeordnet sind. Die Differenz zwischen dem hydrostatischen Druck und dem am selben Ort aufgebrauchten Pressluftdruck ist entweder gleich groß oder nimmt mit wachsender Wassertiefe ab, womit eine Erhöhung der Sogwirkung in Richtung zur Wasseroberfläche erreichbar ist. Die einzelnen Ventile in jeder Pressluftzufuhr sind über eine Steuerung zu öffnen und zu schließen. Beim Anfahren der Vorrichtung wird zunächst die erste Pressluftzufuhr in der geringsten Wassertiefe geöffnet und ein Pressluftdruck eingestellt, der allmählich bis zum in der Wassertiefe vorgesehenen Maximalwert gesteigert wird, der 3 x 105 Pa über dem hydrostatischen Druck liegt. Hiernach wird die zweite Pressluftzufuhr geöffnet und bis zu dem gewünschten Maximalwert gesteigert, was sukzessive bis zu letzten, an der tiefsten Stelle im Saugrohr angeordneten Pressluftzufuhr wiederholt wird. As already mentioned, the applied compressed air pressure must be higher than the hydrostatic pressure prevailing in the water depth where the compressed air is admitted. Preferably, the compressed air pressure is 10 5 to 3 x 10 5 Pa higher than the respective hydrostatic pressure. The distances of the compressed air supply can also be uneven, for example, the first compressed air supply in 25 m, the second in 50 m, the third in 100 m, the fourth in 500 m, the fifth in 1,000 m water depth and possibly each other at a distance of 1,000 m are arranged to the previous compressed air supply. The difference between the hydrostatic pressure and the compressed air pressure used at the same location is either the same or decreases with increasing water depth, whereby an increase in the suction effect in the direction of the water surface can be achieved. The individual valves in each compressed air supply can be opened and closed via a control. When starting the device, first the first compressed air supply is opened in the lowest depth and set a compressed air pressure, which is gradually increased to the maximum depth provided in the water depth, which is 3 x 10 5 Pa above the hydrostatic pressure. After that, the second compressed air supply is opened and increased to the desired maximum value, which is successively repeated until last, arranged at the lowest point in the intake manifold compressed air supply.
Anstelle von Pressluft kann alternativ oder zusätzlich auch ein anderes Fluid oder Fluidgemisch verwendet werden, das gegebenenfalls chemische Zusätze enthält, die abzuforderndes Öl binden lassen. Instead of compressed air, alternatively or additionally, another fluid or fluid mixture may also be used which optionally contains chemical additives which bind the oil to be deposed.
Die Glocke ist vorzugsweise trichterförmig, kegelstumpfförmig oder pyramiden- stumpfförmig ausgebildet. Eine derartige Glocke lässt sich leicht herstellen und ist somit schnell verfügbar. Vorzugsweise besteht die Vorrichtung aus Eisen, Stahl oder zumindest teilweise aus Stahlbeton, der zudem relativ kostengünstig ist. The bell is preferably funnel-shaped, frusto-conical or truncated pyramidal. Such a bell is easy to produce and is thus readily available. Preferably, the device consists of iron, steel or at least partially made of reinforced concrete, which is also relatively inexpensive.

Die im Einsatz unterhalb einer Wasseroberfläche 12 angeordnete Absaugvorrichtung 1 besteht im Wesentlichen aus einer trichterförmigen Glocke 2, einem Saugrohr 3 sowie den Pressluftzuführungen 4', 4", 4"' die axial beabstandet im unteren Bereich der Absaugvorrichtung 1 in das Saugrohr 3 einmünden. Dabei sind endseitig der Pressluftzuführungen 4', 4", 4"' düsenförmige Endstücke 5', 5", 5"' vorgesehen, die derart in die Absaugvorrichtung 1 münden, dass die Pressluft 6 bereits nach oben gerichtet (Pfeil 7) in die Absaugvorrichtung 1 eingepresst wird. Hierdurch entsteht eine Sogwirkung, die die Flüssigkeiten und die Suspensionen entlang der Pfeile 8 an der Unterseite der Absaugvorrichtung 1 einsaugt. Am oberen Ende der Absaugvorrichtung mündet das Absaugrohr in den Rumpf eines Schiffes 9 (Pfeil 10), so dass die Flüssigkeiten, Emulsionen und Suspensionen hiermit abtransportiert werden können. Schließlich ist am unteren Ende der Glocke 2 eine Kameravorrichtung 11 vorgesehen, über die letzten Endes die Bewegung der Glocke gesteuert werden kann, so dass die entsprechenden Unterwasserbereiche gezielt abgesaugt werden können. The arranged in use below a water surface 12 suction device 1 consists essentially of a funnel-shaped bell 2, a suction tube 3 and the compressed air feeds 4 ', 4 ", 4"' axially spaced in the lower region of the suction device 1 in the suction pipe 3 open. Here are the end of the compressed air supply 4 ', 4 ", 4"' nozzle-shaped end pieces 5 ', 5 ", 5"', which open into the suction device 1 that the compressed air 6 already directed upward (arrow 7) in the suction device 1 is pressed. This creates a suction effect, which sucks the liquids and the suspensions along the arrows 8 on the underside of the suction device 1. At the upper end of the suction device, the suction pipe opens into the hull of a ship 9 (arrow 10), so that the liquids, emulsions and suspensions can hereby be transported away. Finally, at the lower end of the bell 2, a camera device 11 is provided, over which the movement of the bell can finally be controlled, so that the corresponding underwater regions can be specifically sucked off.
Fig. 1 b zeigt eine Ausführungsform, bei der drei Pressluftzuführungen 4', 4", 4"' angeordnet sind, die in äquidistanten Abständen A in das Saugrohr 3 münden. Um auch in großen Tiefen Pressluft 6 in das Saugrohr 3 leiten zu können, wo in 2.000 m Tiefe ein Druck von ca. 200 x 105 Pascal (entspricht 200bar) herrscht, wird sukzessive zunächst die Pressluftzuführung 4' und hiernach die Pressluftzuführung 4" und 4"' beaufschlagt. Durch den stetig stärker werdenden Sog verringert sich der hydrostatische Druck, so dass auch Pressluftzuführungen 4', 4", 4"' in großen Tiefen beaufschlagt werden können. Fig. 1 b shows an embodiment in which three compressed air supply lines 4 ', 4 ", 4"' are arranged, which open at equidistant intervals A in the suction pipe 3. In order to be able to conduct compressed air 6 into the intake manifold 3 even at great depths, where a pressure of approximately 200 × 10 5 Pascal (corresponding to 200 bar) prevails at 2,000 m depth, the compressed air supply 4 'and thereafter the compressed air supply 4 "and 4 "'charged. Due to the steadily increasing suction, the hydrostatic pressure is reduced, so that even compressed air supply 4 ', 4 ", 4"' can be applied at great depths.
Nach einer weiteren konkreten Ausgestaltung der Absaugvorrichtung 1 sind an den Pressluftzuführungen 4', 4", 4"' mehrere düsenförmige Endstücke 21 ringförmig angeordnet, und bilden somit die in Fig. 2 a und b dargestellte Ringdüse 22. Hier- durch entsteht die bereits beschriebene starke Strömung, die ein Gefrieren oder Verklumpen der abgesaugten Gase und Flüssigkeiten bzw. des abgesaugten Öls verhindert. Wie insbesondre der Fig. 2b zu entnehmen ist, sind die düsenförmigen Endstücke 21 äquiangular beabstandet angeordnet. According to a further specific embodiment of the suction device 1, a plurality of nozzle-shaped end pieces 21 are annularly arranged on the compressed air feeds 4 ', 4 ", 4"', and thus form the ring nozzle 22 shown in FIGS. 2 a and b. through the already described strong flow, which prevents freezing or clumping of the extracted gases and liquids or the extracted oil. As can be seen insbesondre Fig. 2b, the nozzle-shaped end pieces 21 are arranged equiangularly spaced.
