Abstract

Filter material comprises a flat carrier provided on one side or both sides with an adhesive layer becoming tacky on heating, on which is thermally applied an adsorbent. Production of the filter material is also claimed. Further claimed is an adsorption filter comprising at least two layers of the above filter material.

Description

In der deutschen Patentanmeldung 195 44 990.8 werden Filtermaterialien be­ schrieben, deren gemeinsames Merkmal eine Trägerstruktur ist, die durch Er­ hitzen klebrig wird, so daß daran körnige Adsorbenzien zum Haften gebracht werden können. Es werden damit Filterelemente hergestellt, die sich durch eine ausgezeichnete Kinetik bei geringem Druckverlust auszeichnen.In the German patent application 195 44 990.8 filter materials are wrote, whose common feature is a support structure, which by Er heat becomes sticky so that granular adsorbents adhere to it can be. It is used to manufacture filter elements that stand out have excellent kinetics with low pressure loss.

Es wurde eine weitere elegante Verfahrensweise zur Herstellung von Filterele­ menten nach diesem Prinzip gefunden: Man geht von einer einseitig mit einem Polyolefin beschichteten Metallfolie aus, vorzugsweise einer Aluminiumfolie, wie sie heute für viele Anwendungen eingesetzt wird und in den verschieden­ sten Stärken erhältlich ist. Diese Folie wird auf der Alu-Seite bis auf 200-250°C aufgeheizt und anschließend mit körnigen Adsorbenzien bestreut, die sehr gut haften. Ein einfaches Verfahren besteht darin, daß die mit Polyolefin beschichtete Folie über eine aufgeheizte Trommel geleitet und sofort danach mit den Adsorbenzien bestreut wird, deren Überschuß durch Absaugen oder Abschütteln entfernt wird. Um ein schnelles Aufheizen zu garantieren, sollte die Umschlingung der Trommel mehr als 90°, vorzugsweise 180° oder mehr, betragen. It became another elegant way of making Filterele found according to this principle: one starts from one-sided with one Polyolefin coated metal foil, preferably an aluminum foil, as it is used today for many applications and in different strongest is available. This foil is on up on the aluminum side 200-250 ° C heated and then sprinkled with granular adsorbents, the adhere very well. A simple procedure is that with polyolefin coated film passed over a heated drum and immediately thereafter is sprinkled with the adsorbents, their excess by suction or Shaking is removed. To guarantee a quick heating up, should the wrapping of the drum more than 90 °, preferably 180 ° or more, be.  

Die mit Adsorbenzien beladene Folie kann sowohl zu Rädern aufgewickelt oder zu Paketen geschichtet werden. Die so hergestellten Filter werden immer parallel zur Folie durchströmt. Falls gewünscht, können durch eine Zickzack-Prä­ gung sowohl die Stabilität wie auch die adsorptiven Eigenschaften und der Druckverlust günstig beeinflußt werden. Durch die Größe der Adsorberkörner und deren Menge läßt sich der Druckverlust weitgehend steuern. Weitere Vor­ teile sind die Möglichkeit einer "inneren" Aufheizung durch einen elektrischen Strom für den Desorptionsvorgang, die hohe chemische Resistenz sowie die einfache Verarbeitung.The film loaded with adsorbents can be wound up into wheels or layered into packages. The filters made in this way are always flows parallel to the film. If desired, a zigzag pre stability as well as the adsorptive properties and Pressure loss can be influenced favorably. Due to the size of the adsorber grains and the amount of the pressure loss can be largely controlled. More before parts are the possibility of an "internal" heating by an electrical Electricity for the desorption process, the high chemical resistance and the easy processing.

Interessante Anwendungen der beschriebenen Filter sind Frischluft-Filter für Kfz-Kabinen, Klimaanlagen, aber auch Rotationsadsorber für die Industrie. Kleine zerknüllte Streifen aus dem erfindungsgemäßen Filtermaterial sind als hochluftdurchlässige Füllungen für Schüttfilter verwendbar.Interesting applications of the described filters are fresh air filters for Motor vehicle cabins, air conditioning systems, but also rotary adsorbers for industry. Small crumpled strips from the filter material according to the invention are as Highly air-permeable fillings can be used for bulk filters.

Das bevorzugte Adsorbens ist Aktivkohle, doch können auch anorganische Adsorbenzien, beispielsweise Zeolite oder spezielle Formulierungen, zur Ad­ sorption von H₂S, NH₃ bzw. CO eingesetzt werden. Auch "poröse Polymere", wie sie beispielsweise unter dem Namen SORBATHENE angeboten werden, sind für die Erfindung geeignet.The preferred adsorbent is activated carbon, but inorganic can also Adsorbents, for example zeolites or special formulations, for ad sorption of H₂S, NH₃ or CO can be used. Also "porous polymers", such as those offered under the name SORBATHENE, are suitable for the invention.

Schließlich kann das beschriebene Verfahren für Ionenaustauscher, Speicher­ polymere (Polymere, die mit einem Wirkstoff unterschiedlichster Art beladen oder gefüllt sind und diesen langsam abgeben), aber auch für Silicagel-Perlen, wobei in Zusammenhang mit einer (elektrisch) aufheizbaren Metallfolie als Trä­ ger eine regenerative Trocknung realisiert werden kann, angewandt werden.Finally, the method described for ion exchangers, storage polymers (polymers that are loaded with an active ingredient of all kinds or filled and slowly release it), but also for silica gel beads, whereby in connection with an (electrically) heatable metal foil as Trä regenerative drying can be used.

Bei der Wahl der Aktivkohle sind nur sehr abriebfeste Sorten zu verwenden, da sonst beim Absaugen und Rückführen des Überschusses in die Streuvorrich­ tung Staub entsteht, der die heiße und klebrige Polyolefin-Schicht "abpudern" würde, was zu einer schlechten Haftung der Aktivkohle führen kann.When choosing activated carbon, only very abrasion-resistant grades should be used, because otherwise when the excess is sucked off and returned to the spreading device dust arises which "powder" the hot and sticky polyolefin layer  would, which can lead to poor adhesion of the activated carbon.

Die Dicke der Metallfolie kann je nach Verwendungszweck variieren, sollte aber mindestens 0,005 mm betragen. Die Olefin-Schicht sollte zwecks Errei­ chen einer guten Haftung, insbesondere beim Einsatz von Körnern < 0,2 mm, mindestens 0,005 mm, vorzugsweise mindestens 0,01 mm, betragen.The thickness of the metal foil may vary depending on the intended use but be at least 0.005 mm. The olefin layer should be used for the purpose good adhesion, especially when using grains <0.2 mm, at least 0.005 mm, preferably at least 0.01 mm.

Weiter sei noch erwähnt, daß überall dort, wo eine gute Adsorptionskinetik, je­ doch nur eine geringe Kapazität erforderlich ist, auch pulverförmige Adsorben­ zien verwendet werden können. Baut man aus der mit Adsorbenzien belade­ nen Folien Filterblöcke, so wird der Fachmann durch eine geeignete Prägung bzw. eingelagerte Abstandshalter die Durchlässigkeit des Filters bestimmen.It should also be mentioned that wherever good adsorption kinetics, depending but only a small capacity is required, including powdered adsorbents cien can be used. One builds from the loaded with adsorbents NEN foils filter blocks, the person skilled in the art will use a suitable embossing or stored spacers determine the permeability of the filter.

Eine solche Prägung kann eine Zickzack-Prägung sein. Es können aber auch Noppen- oder Kegelprägungen sein (pyramidales Muster), wobei die Körner in den Tälern, an den Flanken und den Spitzen haften. Eine interessante Varian­ te ist die Prägung mit gleichzeitiger Lochung des Trägers, so daß ein aus sol­ chem Material hergestellter Filterblock sowohl parallel wie auch senkrecht zur Trägerschicht durchströmt werden kann. Dabei sind Löcher mit Durchmessern bis zu 2 mm insbesondere zwischen 1 und 2 mm bevorzugt.Such an embossing can be a zigzag embossing. But it can also Knobs or cones (pyramidal pattern), the grains in cling to the valleys, flanks and peaks. An interesting variant te is the embossing with simultaneous perforation of the carrier, so that a sol Filter block manufactured chem material both parallel and perpendicular to Carrier layer can be flowed through. There are holes with diameters up to 2 mm, in particular between 1 and 2 mm, is preferred.
