Abstract
Description
Die Erfindung betrifft ein Mittel zum Binden von in Flüssig keiten, insbesondere Wasser, enthaltenen flüssigen Stoffen abweichenden spezifischen Gewichtes, wie Öl.The invention relates to a means for binding in liquid liquids, especially water different specific gravity, such as oil.
Das Entfernen von insbesondere schwimmendem Öl aus Gewässern wird bisher überwiegend durch Absaugen des an der Oberfläche des Gewässers befindlichen Öl/Wasser-Gemisches und ein an schließendes Trennen des Öles vom Wasser durchgeführt. Auch Schweröl kann vom Boden von stehenden Gewässern abgesaugt werden. Dabei werden häufig bei der Trennung des Öles von Wasser chemische Mittel eingesetzt, da beim Absaugen einer Öl schicht oder Ölblase eine starke Verwirbelung von Öl mit Was ser auftritt. Es ist auch das Ausbringen von saugfähigem, schwimmfähigen organischen Material vorgeschlagen worden, das sich mit Öl vollsaugen soll und aus welchem das Öl nach der Aufnahme des Materials aus dem Wasser ausgepreßt werden soll. Hier besteht der Nachteil darin, daß das Material nur einmal benutzbar ist und in ausgepreßtem Zustand ölhaltig bleibt und als Sondermüll entsorgt werden müßte. The removal of particularly floating oil from water has so far been mainly by suctioning off the surface of the water / oil mixture and a finally separating the oil from the water. Also Heavy oil can be sucked from the bottom of stagnant water become. Often, when separating the oil from Water chemical agents are used because when vacuuming an oil layer or oil bubble a strong swirling of oil with what this occurs. It's also spreading absorbent, buoyant organic material has been proposed to soak up oil and from which the oil after Recording the material from which water is to be pressed. The disadvantage here is that the material is only once is usable and remains oily in the pressed state and should be disposed of as hazardous waste.
Der Erfindung liegt die Aufgabe zugrunde, ein Hilfsmittel zum Binden von in Gewässern enthaltenen flüssigen Stoffen abwei chenden spezifischen Gewichtes, wie Öl, zu schaffen, das um weltverträglich einsetzbar und wiederholt verwendbar ist.The invention has for its object a tool for Detach binding of liquid substances contained in water specific gravity, such as oil, to create the order is compatible with the world and can be used repeatedly.
Die gestellte Aufgabe wird erfindungsgemäß mit einem Hilfs mittel gelöst, das aus einem schüttfähigen Granulat besteht, bei welchem mindestens die glatte Oberfläche der Granulatkör ner aus einem Kunststoffmaterial besteht.The task is accomplished according to the invention with an auxiliary medium dissolved, which consists of a pourable granulate, in which at least the smooth surface of the granules ner consists of a plastic material.
Es gibt mehrere gängige Kunststoffmaterialien, die insbesonde re durch ihre elektrostatischen Eigenschaften Öl an sich bin den. Es werden Granulatkörner mit einer glatten Oberfläche verwendet, welche das nachträgliche Entfernen des Öles von den Granulatkörnern erleichtert. Vorteilhafterweise können die Granulatkörner Kugelform haben. Ihre Größe und andere physika lische Eigenschaften richten sich nach dem Einsatzgebiet (Seen, Flüsse oder Meer mit stärkerem Wellengang) und auch nach der Viskosität des aufzunehmenden Öls. In jedem Fall bleiben die Granulatkörner so bemessen, daß sie mit einer Absaugvorrichtung von der Gewässeroberfläche oder von einem Gewässerboden abgehoben und einer Schleudervorrichtung zuge führt werden können, wo von den Granulatkörnern das aufgenom mene Öl abgeschleudert wird. Es hat sich gezeigt, daß mitabge saugtes Wasser bereits nach einer kurzen Transportstrecke abfließt, so daß mit den ölbeschichteten Granulatkörnern prak tisch kein Wasseranteil mehr in die Schleudervorrichtung ge langt. Der Einsatz von chemischen Mitteln erübrigt sich voll ständig. Das Kunststoffgranulat kann nach dem Abschleudern sofort wieder in einen Ölteppich oder eine Ölblase ausgebracht werden. Durch die große Durchsatzmenge an Kunststoffgranulat läßt sich mit dem erfindungsgemäß ausgebildeten Hilfmittel eine Ölbeseitigung mit einem guten Wirkungsgrad erzielen, auch wenn die Ölhaftmenge an den einzelnen Granulatkörnern begrenzt und nicht mit saugfähigen Aufnahmekörpern vergleichbar ist. There are several common plastic materials, in particular re due to their electrostatic properties oil in itself the. There are granules with a smooth surface used, which is the subsequent removal of the oil from the Granules relieved. Advantageously, the Granules have a spherical shape. Your size and other physika The properties depend on the area of application (Lakes, rivers or sea with stronger waves) and also according to the viscosity of the oil to be absorbed. In any case the granules remain dimensioned so that they with a Suction device from the surface of the water or from one Lifted the bottom of the water and added a spinner can be carried out where from the granules mene oil is thrown off. It has been shown that mitabge sucked water after a short transport distance flows off, so that with the oil-coated granules practically table no more water in the spinner reaches. The use of chemical agents is completely unnecessary constantly. The plastic granulate can be spun off immediately put back into an oil slick or an oil bladder become. Due to the large throughput of plastic granulate can with the aid designed according to the invention achieve oil removal with good efficiency, too when the amount of oil adhering to the individual granules is limited and is not comparable to absorbent bodies.
Insbesondere Granulatkörner größeren Durchmessern können mehr schichtig aufgebaut sein und beispielsweise aus einem das Gewicht bestimmenden Kern und einer gesonderten Außenschicht mit guten Ölhafteigenschaften bestehen. Der Kern kann bei spielsweise aus gewichtsminderndem Kunststoff-Hartschaum oder aus einem Material, das spezifisch schwerer als die Flüssig keit ist, bestehen.Granules with larger diameters in particular can do more be built up in layers and, for example, from one Weight-determining core and a separate outer layer with good oil adhesion properties. The core can for example made of weight-reducing plastic foam or made of a material that is specifically heavier than the liquid is exist.
Ein weiterer Vorteil des Hilfsmittels besteht darin, daß das Kunststoffgranulat beispielsweise an in Flüssen eingebrachten Ölsperren längere Zeit belassen werden kann. Dabei können vorher die Granulatkörner mit ölabbauenden Bakterien besetzt werden, die vorhandene Restmengen an Öl oder immer wieder auftretende kleinere Ölmengen relativ rasch durch Enzym-Aus scheidungen abbauen können.Another advantage of the tool is that Plastic granules, for example, in rivers Oil barriers can be left for a long time. You can previously the granules were filled with oil-degrading bacteria be, the remaining amount of oil or again and again Smaller amounts of oil occurring relatively quickly due to enzyme-off can settle divorces.
Nachfolgend werden anhand der beiliegenden Zeichnung Form, Aufbau und Wirkungsweise der Granulatkörper näher beschrieben.In the following, using the attached drawing, Structure and mode of action of the granules described in more detail.
Fig. 1 zeigt ein Gewässer 10, auf welchem eine relativ dünne Ölschicht 11 liegt, die beseitigt werden soll. Das aufgegebene schwimmfähige Kunststoffgranulat besteht aus runden Kunst stoffkugeln 12 aus einem Kunststoffmaterial mit guten Ölhaft eigenschaften und mit einer glatten Oberfläche 13. Die Figur läßt erkennen, wie sich auf der glatten Oberfläche 13 der Kunststoffkugeln 12 eine Haftschicht 11.1 aus Öl bildet und ausbreitet. Insbesondere in bewegten Gewässern ist rasch die gesamte Oberfläche der Kunststoffkugeln 12 mit einer Ölhaft schicht 11.1 bedeckt. Die Ölhaftschicht läßt sich durch Schleudern der Kunststoffkugeln 12 und die dabei auftretenden Zentrifugalkräfte anschließend entfernen und in einen Sammel behälter leiten. Die Kunststoffkugeln 12 können anschließend sofort wieder ausgebracht werden. Fig. 1 shows a body of water 10 on which there is a relatively thin oil layer 11 which is to be removed. The abandoned floating plastic granulate consists of round plastic balls 12 made of a plastic material with good oil-holding properties and with a smooth surface 13 . The figure shows how an adhesive layer 11.1 of oil forms and spreads on the smooth surface 13 of the plastic balls 12 . Particularly in moving waters, the entire surface of the plastic balls 12 is quickly covered with an oil adhesive layer 11.1 . The oil adhesive layer can then be removed by spinning the plastic balls 12 and the centrifugal forces that occur and pass them into a collecting container. The plastic balls 12 can then immediately be deployed again.
Insbesondere größere Granulatkörner können auch mehrschichtig ausgebildet sein. Fig. 2 zeigt ein Granulatkorn 14, das einen aus Kunststoff-Hartschaum bestehenden Kern 15 aufweist, der nachträglich mit einer Außenschicht 16 aus einem Kunststoff material mit guten Hafteigenschaften versehen ist, welche auch die glatte Außenfläche 17 des Granulatkornes 14 bildet.Larger granules, in particular, can also be constructed in multiple layers. Fig. 2 shows a granulate 14 , which has a core made of rigid plastic foam 15 , which is subsequently provided with an outer layer 16 made of a plastic material with good adhesive properties, which also forms the smooth outer surface 17 of the granulate 14 .
