Filtereinrichtuncr Filter device
Die vorliegende Erfindung betrifft eine Filtereinrichtung für Gasströme, insbes. für Luft.The present invention relates to a filter device for gas streams, in particular for air.
Filteranlagen zur Reinigung der Atem- bzw. ümgebungsluft finden in den verschiedensten Bereichen Anwendung, wobei die Anwendung in Kraftfahrzeugen, im Wohn- oder Arbeitsbereich sowie in Einsatzfahrzeugen unterschiedlichster Art die häufigsten sind. Die in derartigen Filteranlagen eingesetzten Filterelemente reichen von einfachen Partikelfiltern über Adsorberfilter unterschiedlichster Ausgestaltung bis hin zu kombinierten Partikel- und Absorberfiltern, wie z.B. aus der EP O 383 bekannt.Filter systems for cleaning breathing or ambient air are used in a wide variety of areas, with the most common being in motor vehicles, in living or working areas, and in various types of emergency vehicles. The filter elements used in such filter systems range from simple particle filters to adsorber filters of various designs to combined particle and absorber filters, such as those known from EP O 383.
Aus der DE-OS 32 12 289 ist ein Filter zum Reinigen der Luft für nach außen abgeschlossene Räume, insbes. für Fahrzeuge, bekannt. Der offenbarte Filter ist in eine Belüftungsanlage eines Kraftfahrzeugs einsetzbar, wobei dieser Filter als Schwebstoffilter oder kombinierter Schwebstoff-Gasadsorptionsfilter ausgebildet ist und die unterschiedlich ausgebildeten Filter je nach den Anforderungen austauschbar sind.From DE-OS 32 12 289, a filter for cleaning the air in rooms closed to the outside, in particular for vehicles, is known. The filter disclosed can be used in a ventilation system of a motor vehicle, whereby this filter is designed as a particulate filter or a combined particulate gas adsorption filter and the differently designed filters are interchangeable depending on the requirements.
Darüberhinaus sind verschiedene Arten von Partikel- und Adsorptionsfiltermaterialien sowie an spezielle Anwendungen angepaßte Filtereinrichtungen bzw. -anlagen allgemein bekannt. Bei den bekannten Filtereinrichtungen bzw. -anlagen ist jedoch nachteilig, daß sie auf bestimmte Anwendungen beschränkt und nicht universell einsetzbar sind.In addition, various types of particle and adsorption filter materials as well as filter devices and systems adapted to specific applications are generally known. However, the disadvantage of the known filter devices and systems is that they are limited to certain applications and cannot be used universally.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Filtereinrichtung zu schaffen, die auf einfache Weise an verschiedenste Anforderungen angepaßt werden kann, die wirtschaftlich herstellbar ist und deren Einzelteile in hohem Maße einer Wiederverwertung zuführbar sind.It is therefore the object of the present invention to create a filter device which can be easily adapted to a wide variety of requirements, which can be produced economically and whose individual parts can be recycled to a large extent.
Die vorliegende Aufgabe wird durch eine Filtereinrichtung, bestehend aus einem Kassettenrahmen, wenigstens zwei in dem Kassettenrahmen in Strömungsrichtung hintereinander angeordneten Modulrahmen, wobei in den Modulrahmen jeweils ein verschieden ausgebildetes Filterelement befestigt ist und die Modulrahmen lösbar in dem Kassettenrahmen befestigt sind, und wobei die Modulrahmen so ausgebildet sind, daß sie untereinander austauschbar sind, gelöst.The present object is achieved by a filter device consisting of a cassette frame, at least two module frames arranged one behind the other in the cassette frame in the flow direction, wherein a differently designed filter element is fastened in each of the module frames and the module frames are detachably fastened in the cassette frame, and wherein the module frames are designed such that they are interchangeable with one another.
Durch die erfindungsgemäße Anordnung entsteht der Vorteil, daß durch die geeignete Auswahl der in den Modulrahmen befestigten Filterelemente verschiedene Gase, z.B. aromatische Kohlenwasserstoffe (BTX) und polyzyklische Kohlenwasserstoffe (PAH) sowie Schwefeldioxid und/oder Kohlenmonoxid, gleichzeitig effektiv aus der zu reinigenden Luft entfernt werden können. Da die Modulrahmen untereinander austauschbar sind, ist es z.B. günstig, die Reihenfolge der verschiedenen hintereinandergeschalteten Filterelemente so zu wählen, daß selektive Adsorbentien den Stoff, der erwartungsgemäß in einer bestimmten Umgebung in der höchsten Konzentration vorliegt, alsThe arrangement according to the invention has the advantage that through the appropriate selection of the filter elements attached to the module frame, various gases, e.g. aromatic hydrocarbons (BTX) and polycyclic hydrocarbons (PAH) as well as sulphur dioxide and/or carbon monoxide, can be effectively removed simultaneously from the air to be cleaned. Since the module frames are interchangeable, it is advantageous, for example, to select the order of the various filter elements connected in series so that selective adsorbents select the substance that is expected to be present in the highest concentration in a certain environment as
erstes adsorbieren wird, und der Stoff, der in der geringsten Konzentration vorliegt, als letztes. Dabei können die einzelnen Modulrahmen mit den unterschiedlichen Filterelementen auch entsprechend dem tatsächlichen Schadstoffanfall in unterschiedlichen Zeit-Intervallen ausgetauscht werden.will be adsorbed first, and the substance that is present in the lowest concentration will be adsorbed last. The individual module frames with the different filter elements can also be exchanged at different time intervals depending on the actual amount of pollutants.
Zum Einsatz der Filtereinrichtung in einer Umgebung, in der eine gewisse Staubbelastung der zu reinigenden Luft zu erwarten ist, ist bevorzugt, wenn in Strömungsrichtung wenigstens ein Modulrahmen angeordnet ist, dessen Filterelement als Partikelfilter ausgebildet ist, und wenigstens zwei Modulrahmen, deren Filterelemente durch unterschiedliche Adsorptionsfilter gebildet sind. Diese Ausgestaltung ist zweckmäßig, weil der vorgeschaltete Partikelfilter entsprechend der anfallenden Partikelmenge und -größe gewählt werden kann und dadurch ein frühzeitiger Austausch des bzw. der nachgeschalteten Adsorptionsfilter wegen zu großer Partikelaufnahme vermieden wird. Des weiteren wird bei entsprechender Anpassung des Partikelfilters an die Partikelgröße und/oder an die Partikelmenge das Strömungsverhalten durch die Filtereinrichtung nicht unnötig beeinträchtigt, d.h. der durch den Partikelfilter verursachte Druckabfall ist nicht größer als erforderlich, da die Dichte des Partikelfilters entsprechend der zu entfernenden Partikel wählbar ist.For use of the filter device in an environment in which a certain dust load is to be expected in the air to be cleaned, it is preferred if at least one module frame is arranged in the flow direction, the filter element of which is designed as a particle filter, and at least two module frames whose filter elements are formed by different adsorption filters. This design is useful because the upstream particle filter can be selected according to the amount and size of particles generated, thus avoiding premature replacement of the downstream adsorption filter(s) due to excessive particle absorption. Furthermore, if the particle filter is adapted accordingly to the particle size and/or the amount of particles, the flow behavior through the filter device is not unnecessarily impaired, i.e. the pressure drop caused by the particle filter is not greater than necessary, since the density of the particle filter can be selected according to the particles to be removed.
Um zu vermeiden, daß die Abluft der Filtereinrichtung Partikel enthält, die z.B. aus den Adsorbentien stammen, ist es sinnvoll, daß ein Modulrahmen, dessen Filterelement als Partikelfilter ausgebildet ist, in Strömungsrichtung als letzter Modulrahmen in dem Kassettenrahmen angeordnet ist. Dieser nachgeschaltete Partikelfilter besteht zweckmäßigerweise aus einem Vlies mit einer sehr großen äußeren Oberfläche, wobeiIn order to avoid the exhaust air from the filter device containing particles, which originate from the adsorbents, for example, it is sensible that a module frame, the filter element of which is designed as a particle filter, is arranged as the last module frame in the cassette frame in the flow direction. This downstream particle filter is expediently made of a fleece with a very large outer surface, whereby
die Fasern ausschließlich aus Mikrofasern bestehen, weil dadurch auch sehr kleine Partikel entfernt werden.the fibres consist exclusively of microfibres because this removes even very small particles.
Durch die Anordnung der Filterelemente in den Modulrahmen ist eine einfache und unkomplizierte Handhabung gewährleistet, insbes. wird der Austausch der einzelnen Module bedeutend erleichtert. Um jedoch eine möglichst gute Wxederverwertbarkeit zu ermöglichen, ist es besonders vorteilhaft, die Filterelemente in den Modulrahmen lösbar zu befestigen, so daß der Modulrahmen wieder verwendet und das beladene Filterelement recycelt werden kann. Da aber auch die Modulrahmen eine begrenzte Lebensdauer haben können, auch wenn diese viele Filterzyklen betragen kann, sind die Modulrahmen vorzugsweise aus dem gleichen Material wie die einzelnen Träger der Adsorptionsmittel hergestellt, so daß Modulrahmen und Filterelement gemeinsam einer Wiederverwertung zugeführt werden können.The arrangement of the filter elements in the module frames ensures simple and uncomplicated handling, in particular the replacement of the individual modules is made significantly easier. However, in order to enable the best possible recyclability, it is particularly advantageous to attach the filter elements detachably to the module frame so that the module frame can be reused and the loaded filter element recycled. However, since the module frames can also have a limited lifespan, even if this can be many filter cycles, the module frames are preferably made of the same material as the individual adsorbent carriers, so that the module frame and filter element can be recycled together.
In einer besonderen Ausgestaltung der vorliegenden Erfindung enthält ein Modulrahmen zwei oder mehr unterschiedliche Filterelemente, wodurch ermöglicht wird, verschiedene Stoffe auf sehr wenig Raum aus dem zu reinigenden Medium zu entfernen.In a particular embodiment of the present invention, a module frame contains two or more different filter elements, which makes it possible to remove different substances from the medium to be cleaned in a very small space.
Um unabhängig von den am Einsatzort des Filters vorliegenden Strömungsverhältnissen und um eine gleichmäßige Durchströmung der Filtereinrichtung sicherzustellen, ist es vorteilhaft vor den eigentlichen Filtermodulen einen Modulrahmen in dem Kassettenrahmen anzuordnen, in dem ein Diffusor oder eine Blende anstelle eines Filterelements oder eine Blende bzw. ein Diffusor oder eine Blende und wenigstens ein Filterelement, z.B. ein Partikelfilter, enthalten ist.In order to ensure a uniform flow through the filter device regardless of the flow conditions at the location where the filter is used, it is advantageous to arrange a module frame in the cassette frame in front of the actual filter modules, in which a diffuser or a cover instead of a filter element or a cover or a diffuser or a cover and at least one filter element, e.g. a particle filter, is contained.
Die beschriebene Filtereinrichtung kann grundsätzlich in jeder geforderten Größe hergestellt werden, so daß sowohl ein EinsatzThe filter device described can basically be manufactured in any required size, so that both the use
I.I.
in Kraftfahrzeugen als auch in Gebäuden u.dgl. möglich ist. Die verwendeten Filtermaterialien sind dem Fachmann allgemein aus dem Stand der Technik bekannt, wobei bei den Adsorptionsfiltern solche bevorzugt sind, die aus auf Trägern aufgebrachten Adsorptionsteilchen mit einem Durchmesser von etwa 0,1 bis etwa 1 mm bestehen. Zweckmäßigerweise bestehen die Träger aus retikuliertem PUR-Schaum, Honeycomb-Strukturen oder textilem Flächengebilde. Besonders bevorzugt sind Träger aus textilen Flächengebilden, die plissiert sind, d.h. zick-zack-förmig gefaltet.in motor vehicles as well as in buildings etc. The filter materials used are generally known to the person skilled in the art from the state of the art, with preference being given to adsorption filters which consist of adsorption particles applied to supports with a diameter of about 0.1 to about 1 mm. The supports are expediently made of reticulated PUR foam, honeycomb structures or textile fabrics. Particularly preferred are supports made of textile fabrics which are pleated, i.e. folded in a zigzag shape.
Je nach Anwendung bestehen die Modulrahmen zweckmäßigerweise aus Textil, Folie, Hotmelt oder kartonartigem Material.Depending on the application, the module frames are made of textile, foil, hot melt or cardboard-like material.
Zur Vermeidung von Stabilitätsprobleraen sind die Träger für das Adsorptionsmaterial in einer bevorzugten Ausgestaltung der vorliegenden Erfindung selbsttragend ausgebildet und somit gegebenenfalls auch in der Lage, den Modulrahmen zu stabilisieren.In order to avoid stability problems, the supports for the adsorption material are designed to be self-supporting in a preferred embodiment of the present invention and are therefore also able to stabilize the module frame if necessary.
In der Zeichnung ist eine erfindungsgemäße Filtereinrichtung beispielhaft dargestellt. Die Schemazeichnung zeigt eine erfindungsgemäße Filtereinrichtung mit einem Kassettenrahmen 1, in dem drei Modulrahmen 2, 2', 2'' angeordnet sind, wobei in dem Modulrahmen 2, 2', 2'' verschieden ausgebildete Filterelemente 3, 3', 3'' befestigt sind. In der Darstellung wird das Filterelement 3 durch eine Honeycomb-Struktur gebildet, wie sie z.B. als Partikelfilter Verwendung findet, Filterelement 3' durch einen retikulierten PUR-Schaum mit Adsorbern und Filterelement 3'' durch ein plissiertes textiles Flächengebilde mit Adsorbern.The drawing shows an example of a filter device according to the invention. The schematic drawing shows a filter device according to the invention with a cassette frame 1 in which three module frames 2, 2', 2'' are arranged, with differently designed filter elements 3, 3', 3'' being attached to the module frames 2, 2', 2''. In the illustration, the filter element 3 is formed by a honeycomb structure, such as is used as a particle filter, filter element 3' by a reticulated PUR foam with adsorbers and filter element 3'' by a pleated textile fabric with adsorbers.
Die folgenden beiden Ausführungsbeispiele erläutern anschaulich die Wirksamkeit und die Vorteile der vorliegenden Erfindung.The following two embodiments clearly illustrate the effectiveness and advantages of the present invention.
Zwei aus retikuliertem PUR-Schaum der Dicke 5,8 nun bestehende Filtermatten werden mit einem geeigneten Klebersystem imprägniert und mit hochaktiver granulatförmiger Aktivkohle belegt. Die Filtermatten besitzen eine Größe von 165 &khgr; 165 mm und werden unter Verwendung eines Polyamid-Gewirkes umhüllt. Das so erhaltene Filterelement wird in einem Modulrahmen von 40 mm Höhe befestigt.Two filter mats made of reticulated PUR foam with a thickness of 5.8 are impregnated with a suitable adhesive system and covered with highly active granular activated carbon. The filter mats have a size of 165 x 165 mm and are covered using a polyamide knit. The filter element thus obtained is attached to a module frame with a height of 40 mm.
Ein zweites Filterelement wird dadurch hergestellt, daß ein PES-Vlies punktförmig mit einem geeigneten Klebersystem beschichtet und ebenfalls mit hochaktiver granulatförmiger Aktivkohle belegt wird. Das verwendete PES-Vlies ist zweilagig und wird nach dem Belegen mit Aktivkohle auf eine Faltenhöhe von 19 mm plissiert. Dieses Filterelement wird dann in einen weiteren Modulrahmen von 40 mm Höhe befestigt. Das Filterelement besitzt dabei ebenfalls eine Größe von 165 &khgr; 165 mm und weist in einer Richtung 20 Falten auf.A second filter element is produced by spot-coating a PES fleece with a suitable adhesive system and also covering it with highly active granular activated carbon. The PES fleece used is two-layered and is pleated to a fold height of 19 mm after being covered with activated carbon.
