MassenkraftabscheiderInertia
Gebiet der ErfindungField of the Invention
Die vorliegende Erfindung betrifft einen Massenkraftabscheider zur Ausfilterung von Partikeln aus einem Flussigkeits- oder Gasstrom. Insbesondere betrifft die Erfindung einen solchen Massenkraftabscheider für die Luftfiltration bei Vorabscheidern sowie bei Luftführungsteilen.The present invention relates to a mass separator for filtering out particles from a liquid or gas stream. In particular, the invention relates to such a mass separator for air filtration in pre-separators and in air duct parts.
Hintergrund der Erfindung, Stand der TechnikBackground of the Invention, State of the Art
Die Filtration stellt eines der wichtigsten Trennverfahren für Stoff-Gemische dar. Mit ihrer Hilfe können bspw. Feststoffteilchen aus Flüssigkeiten (Suspensionen) oder aus Gasen (Staub) , und auch nichtlösliche Flüssigkeitströpfchen aus einer anderen Flüssigkeit (Emulsion) , sowie aus Gasen (Aerosole) getrennt werden. Je nach Art des Stoff-Gemisches werden unterschiedliche Filter bzw. Filterelemente zur Trennung verwendet .Filtration is one of the most important separation processes for mixtures of substances. With its help, for example, solid particles from liquids (suspensions) or gases (dust), and also insoluble liquid droplets from another liquid (emulsion), as well as gases (aerosols) be separated. Depending on the type of substance mixture, different filters or filter elements are used for separation.
So ist bspw. bekannt, dass Filterelemente für zu filternde Medien, wie Flüssigkeiten oder Luft, so konstruiert sein können, dass die ausgefilterten Partikel durch mechanische Vorrichtungen, wie Schaber oder Bürsten, entfernt werden. Es ist auch bekannt, mit sogenannten Rückspül- oder Querstromfiltern mittels einer Strömungsumkehr oder einer Querströmung der zu filternden Flüssigkeit eine Reinigung der Filteroberfläche bzw. der Filtermembran vorzunehmen. Die Wirksamkeit dieser bekannten Reinigungsmethoden ist wesentlich von der Spalt-, Loch- oder Porengeometrie des Materials des Filterelements, sowie der äußeren Geometrie und Beschaffenheit des Filterelements abhängig, wobei diese Eigenschaften auch von den physikalischen Eigenschaften der zu filternden Flüssigkeit oder des Gases beeinflusst werden.For example, it is known that filter elements for media to be filtered, such as liquids or air, can be constructed in such a way that the filtered-out particles are removed by mechanical devices, such as scrapers or brushes. It is also known to clean the filter surface or the filter membrane with so-called backwash or crossflow filters by means of a flow reversal or a crossflow of the liquid to be filtered. The effectiveness of these known cleaning methods is essentially dependent on the gap, hole or pore geometry of the material of the filter element, and on the external geometry and nature of the filter element, these properties also being influenced by the physical properties of the liquid or gas to be filtered.
Viele unterschiedliche Filtermaterialien sind bereits zur Erzeugung eines für auszufilternde Partikel, eine durchströmende Flüssigkeit und/oder einen Gasstrom optimalen Filterverhaltens vorgeschlagen worden. Für die Abluftreinigung zur Entfernung von Stäuben aus Abgasen haben Faser- und Gewebefilter Bedeutung erlangt. Während früher als Filtermedien fast ausschließlich Gewebe (Tuche) verwendet wurden, handelt es sich heute hauptsächlich um nichtgewebte Stoffe wie Vliese oder sogar Nadelfilze. So ist bspw. aus der DE-A-44 43 158 bekannt, ein Meltblown-Vlies als Filtermedium in einem Gasstrom zusammen mit einem ausschließlich zur Stabilisierung dienenden Trägermaterial einzusetzen.Many different filter materials have already been proposed for producing a filter behavior which is optimal for particles to be filtered out, a liquid flowing through and / or a gas flow. Fiber and fabric filters have become important for exhaust air purification to remove dust from exhaust gases. While in the past almost exclusively fabrics (cloths) were used as filter media, today they are mainly non-woven fabrics such as fleeces or even needle felts. For example, it is known from DE-A-44 43 158 to use a meltblown nonwoven as a filter medium in a gas stream together with a support material used exclusively for stabilization.
In der ÜS-A-5, 96, 627 und der WO 95/17946 ist die Hintereinanderschaltung von Filtermedien aus synthetischen Fasern mit abgestufter Filterfeinheit beschrieben, wobei hier die Filterfeinheit der Filterlagen in Strömungsrichtung zunimmt.In the ÜS-A-5, 96, 627 and WO 95/17946 the series connection of filter media made of synthetic fibers with graded filter fineness is described, the filter fineness of the filter layers increasing in the direction of flow.
Schließlich ist es aus der DE 197 38 376 AI bekannt, ein Filterelement zu verwenden, bei dem mindestens dessen Anströmseite mit einer Schicht aus Nanomeren versehen ist. Die Nanomerenschicht weist bspw. Nanokörner auf, deren Abmessungen kleiner als 1000 nm sind.Finally, it is known from DE 197 38 376 AI to use a filter element in which at least its upstream side is provided with a layer of nanomers. The nanomer layer has, for example, nanograins whose dimensions are less than 1000 nm.
Bei all diesen bekannten Filterelementen wird jeweils das Filtermedium von dem Flussigkeits- bzw. Gasstrom durchströmt und dabei die zu trennenden Partikel aus diesem entfernt. Eine völlig andere Technik findet bei den sogenannten Massenkraftabscheidern Anwendung, die vor allem in der Enstaubung, d.h., bei der Entfernung von Feststoffteilchen aus Gasen, verwendet werden. In Massenkraftabscheidern werden allein Massenkräfte, d.h., Schwerkraft, Trägheitskraft und Zentrifugalkraft, einzeln oder gemeinsam genutzt.In all of these known filter elements, the filter medium is flowed through by the liquid or gas stream and the particles to be separated are removed from it. A completely different technique is used for the so-called mass force separators, which are used primarily in dedusting, ie when removing solid particles from gases. In mass force separators, only mass forces, ie, gravity, inertia and centrifugal force, are used individually or together.
Ein Beispiel für einen solchen Massenkraftabscheider sind die Zyklone, die insbesondere in der Luftfiltration bei der Vorabscheidung in zunehmendem Masse eingesetzt werden. Zyklone sind Geräte zur Abscheidung von Staub oder Flüssigkeitströpfchen mit Hilfe der Flieh- oder Schwerkraft. Sie bestehen im Prinzip aus einem zylindrischen Gefäß mit konisch zulaufendem Boden, in das oben das Staubluft-Eintrittsrohr tangential und das Reinluft-Austrittsrohr vertikal hineinragen. Der tangential eintretende Gas/Staub-Strom induziert eine Wirbelströmung, wobei die größeren Staubteilchen durch die Zentrifugalkraft an die Wand des Zylinders geschleudert werden und von dort durch die Schwerkraft zu Boden sinken, von wo sie ausgetragen werden. Der kreisende, vom Staub befreite Gaswirbel kehrt am Boden des Zyklons seine Richtung um und verläßt den Zyklon nach oben durch das Austrittsrohr zusammen mit eventuell feineren Partikeln, denn das Trennprinzip reicht nicht aus, um Feinstaub- Verunreinigungen mit Partikelgrößen < ca. 5 μ zu beseitigen, weswegen Zyklone meist als Vorabscheider eingesetzt werden.An example of such a mass force separator are the cyclones, which are increasingly being used in particular in air filtration for pre-separation. Cyclones are devices for separating dust or liquid droplets using centrifugal or gravity. They basically consist of a cylindrical vessel with a tapered bottom into which the dust air inlet pipe protrudes tangentially and the clean air outlet pipe projects vertically. The gas / dust flow entering tangentially induces a vortex flow, whereby the larger dust particles are thrown against the wall of the cylinder by centrifugal force and sink to the bottom from there by gravity, from where they are discharged. The rotating, dust-free gas vortex reverses its direction at the bottom of the cyclone and leaves the cyclone upwards through the outlet pipe together with possibly finer particles, because the separation principle is not sufficient to remove fine dust impurities with particle sizes <approx. 5 μ , which is why cyclones are mostly used as pre-separators.
Da die Staubteilchen, wie oben beschrieben, durch die Zentrifugalkraft an die Wand des Zylinders geschleudert werden, kann beim Vorhandensein von harten Teilchen eine Verrauhung der Zylinder (Pfeifen) des Zyklons entstehen. Dadurch wird der Wirkungsgrad eines Zyklons erheblich beeinträchtigt.Since the dust particles are thrown against the wall of the cylinder by the centrifugal force, as a result of the presence of hard particles, the cylinders (whistles) of the cyclone can become rough. This considerably affects the efficiency of a cyclone.
Außerdem kann es zu einer elektrostatischen Aufladung der Oberfläche des Zylinders kommen, was die Funktion des Zyklons empfindlich beeinträchtigen kann.In addition, there may be an electrostatic charge on the surface of the cylinder, which affects the cyclone's function can significantly affect.
Aufgabe der vorliegenden Erfindung ist es daher, einen Massenkraftabscheider der gattungsgemäßen Art bereitzustellen, der die vorgenannten Nachteile des Standes der Technik vermeidet .The object of the present invention is therefore to provide a mass separator of the generic type which avoids the aforementioned disadvantages of the prior art.
Zusammenfassung der ErfindungSummary of the invention
Diese und weitere Aufgaben und Vorteile werden durch einen Massenkraftabscheider zur Ausfilterung von Partikeln aus einem Flussigkeits- oder Gasstrom erreicht, der dadurch gekennzeichnet ist, dass die filternde Oberfläche mit Fullerenen beschichtet ist .These and other tasks and advantages are achieved by a mass separator for filtering out particles from a liquid or gas stream, which is characterized in that the filtering surface is coated with fullerenes.
In einer vorteilhaften Ausgestaltung der Erfindung liegt die Dicke der Fulleren-Schicht im Nanometer-Bereich.In an advantageous embodiment of the invention, the thickness of the fullerene layer is in the nanometer range.
Bei einer vorteilhaften Ausführungsform der vorliegenden Erfindung ist der Massenkraftabscheider ein Zyklon.In an advantageous embodiment of the present invention, the mass force separator is a cyclone.
In einer weiteren vorteilhaften Ausführungsform der vorliegenden Erfindung handelt es sich bei dem Massenkraftabscheider um ein Hydro-Zyklon.In a further advantageous embodiment of the present invention, the inertial force separator is a hydro-cyclone.
Detaillierte Beschreibung der AusführungsbeispieleDetailed description of the exemplary embodiments
Bei den vor noch nicht allzu langer Zeit entdeckten Fullerenen handelt es sich um eine dritte Modifikation des Kohlenstoffs. Anders als beim Graphit oder Diamant bestehen Fullerene aus kugelsymmetrischen Molekülen genau definierter Größe. Sie enthalten zwischen 28 und etwa 540 Kohlenstoffatome und bilden große Kohlenstoff-Käfigmoleküle. Das bekannteste ist dabei das Cgo-Molekül, das sich aus 12 Fünfecken und 20 Sechsecken zusammensetzt. Ihre Bauweise bedingt einen Hohlraum im inneren, der neue Möglichkeiten der Verwendung eröffnet. Dieser aufblasbare Hohlraum bietet zusätzlich zur riesigen Oberfläche der Fullerene, an die andere Elemente "andocken" können, die Möglichkeit, andere Substanzen einzufüllen.The fullerenes discovered not so long ago are a third modification of carbon. In contrast to graphite or diamond, fullerenes consist of spherically symmetrical molecules of a precisely defined size. They contain between 28 and about 540 carbon atoms and form large carbon cage molecules. The best known is that Cgo molecule, which is composed of 12 pentagons and 20 hexagons. Their design requires a cavity inside, which opens up new possibilities for use. In addition to the huge surface of the fullerenes to which other elements can "dock", this inflatable cavity offers the possibility of filling in other substances.
Fullerene sind ca. hundert mal härter als Stahl, haben einen geringeren Abrieb als Diamant, sind elektrisch hoch leitfähig und dazu billig in der Herstellung.Fullerenes are approx. 100 times harder than steel, have less abrasion than diamond, are highly electrically conductive and are cheap to manufacture.
Beschichtet man die filternde Oberfläche einesIf you coat the filtering surface of a
Massenkraftabscheiders mit einer Schicht aus Fullerenen, so kann man dessen Wirkungsgrad sehr stark verbessern. Durch die große Härte wird eine Verrauhung der Oberfläche durch harte Teilchen in wirkungsvoller Weise verhindert. Außerdem kann eine starke elektrostatische Aufladung der Oberfläche des Massenkraftabscheiders verhindert werden, da die hohe Leitfähigkeit der Fulleren-Beschichtung zu einer Abführung der Aufladung der Pfeifen führt.Mass separator with a layer of fullerenes, its efficiency can be greatly improved. Due to the great hardness, roughening of the surface due to hard particles is effectively prevented. In addition, a strong electrostatic charge on the surface of the mass force separator can be prevented, since the high conductivity of the fullerene coating leads to the discharge of the charge on the pipes.
Eine Beschichtung der filtrierenden Oberfläche eines Massenkraftabscheiders mit Fullerenen führt also zu einer Oberfläche, die einerseits elektrisch hoch leitend und andererseits widerstandsfähig wie Diamant ist.A coating of the filtering surface of a mass separator with fullerenes thus leads to a surface which is on the one hand highly electrically conductive and on the other hand as resistant as diamond.
Bei den Massenkraftabscheidern kann es sich bspw. um ein Zyklon handeln, bei dem Partikel aus dem Medium Luft abgetrennt werden. Auch die Verwendung eines sogenannten Hydro-Zyklons ist möglich. Bei dieser Art von Massenkraftabscheider sind die abzuscheidenden Partikel in eine Flüssigkeit eingebunden. Bei Verwendung eines Hydro-Zyklons stellt sich der zusätzliche Vorteil ein, dass die filternde Oberfläche nicht mehr benetzt wird, was zu einer weiteren Verbesserung des Wirkungsgrades solcher Abscheider beiträgt. Es ist jedoch anzumerken, dass die vorliegende Erfindung nicht auf Zyklone beschränkt ist, sondern dass jeder Massenkraftabscheider verwendet werden kann.The mass force separators can be, for example, a cyclone in which particles are separated from the air. The use of a so-called hydro cyclone is also possible. In this type of mass separator, the particles to be separated are integrated in a liquid. When using a hydro cyclone, there is the additional advantage that the filtering surface is no longer wetted, which contributes to a further improvement in the efficiency of such separators. However, it should be noted that the present invention is not limited to cyclones, but that any inertial force separator can be used.
Die Dicke der Fulleren-Schicht liegt vorzugsweise im Nanometer- Bereich. Dabei kann die Beschichtung der Oberfläche mittels bekannter Techniken, bspw. durch Plasmabeschichtung oder dgl., erfolgen. The thickness of the fullerene layer is preferably in the nanometer range. The surface can be coated using known techniques, for example by plasma coating or the like.
