Abstract

The cylindrical filter cartridge has a filter element which consists of open-pore, cross-linked polyurethane (PU) foam loaded with adsorbents and formed into a cylinder. The foam has grooves on the inside to compensate for the difference between the outer and inner circumference of the element.

Description

Mit steigendem Umweltbewußtsein und heutigen Erkenntnissen hinsichtlich der Auswirkungen zahlreicher Luftschadstoffe auf die Gesundheit, aber auch auf industrielle Fertigungen (z. B. elektronische Bausteine, Mikrochips) stellt man einen stetig steigenden Bedarf an Systemen zur Entfernung von in sehr geringen Konzentrationen vorkommenden Schadstoffen in großen Luftmassen fest. Hierzu werden fast ausnahmslos Adsorptionsfilter auf Aktivkohlebasis eingesetzt. Sehr gut bewährt haben sich dabei Filter, bei denen A-Kohle-Parti­ kel mit Teilchengrößen von ca. 0,3-1 mm an einer dreidimensionalen Matrix haften, so daß die für die Kinetik wichtige Kleinheit der Teilchen mit einer sehr hohen Luftdurchlässigkeit kombiniert werden konnte (DE 38 13 563 A1). Eine bevorzugte Form ist ein retikulierter PU-Schaum, der mit einer klebrigen Haft­ masse beaufschlagt und mit Aktivkohlekügelchen oder -körnchen bestreut wird. Man fertigt so praktisch selbsttragende und selbstabdichtende Matten, die sich leicht in vorhandene Systeme integrieren lassen. Die deutsche Pa­ tentschrift DE 41 19 661 C2 beschreibt einen Weg, um die relativ steifen Fil­ terplatten in Zickzack-Form anwenden zu können: Durch bereits vor dem Auf­ bringen des Klebers beidseitig in der Schaumbahn angebrachte Einschnitte läßt sich der beladene Schaum sehr gut knicken bzw. um die Stützstäbe le­ gen.With increasing environmental awareness and current knowledge regarding the effects of numerous air pollutants on health, but also on industrial production (e.g. electronic components, microchips) one has a steadily increasing need for systems for removing in very low concentrations of pollutants occurring in large air masses firmly. For this purpose, almost exclusively adsorption filters based on activated carbon are used used. Filters in which A-charcoal parties have proven to be very effective with particle sizes of approx. 0.3-1 mm on a three-dimensional matrix adhere so that the smallness of the particles with a very important for the kinetics high air permeability could be combined (DE 38 13 563 A1). A preferred form is a reticulated PU foam with a sticky stick mass applied and sprinkled with activated carbon beads or granules becomes. You practically manufacture self-supporting and self-sealing mats, that can be easily integrated into existing systems. The German Pa tentschrift DE 41 19 661 C2 describes a way to the relatively stiff Fil to be able to use zigzag-shaped panels: by already before opening make cuts on both sides in the foam sheet the loaded foam can be bent very well or around the support rods gene.

Wegen des für die Schüttung charakteristischen hohen Druckverlustes wurde versucht, den Filterquerschnitt zu erhöhen und die Dicke zu reduzieren. So wurden Schüttungen von stäbchenförmiger Aktivkohle zwischen zwei paralle­ len Gittern entwickelt, die aber oft Durchbrüche im oberen Teil aufwiesen. Hier ist der Ersatz durch eine Filterplatte nach EP 340 542 sehr einfach. Because of the high pressure loss characteristic of the fill tries to increase the filter cross section and reduce the thickness. So were piles of rod-shaped activated carbon between two paralle len grids developed, but often had openings in the upper part. Here replacement with a filter plate according to EP 340 542 is very simple.  

In einer anderen Ausführung werden eine Reihe von parallel angeordneten, auf einer Seite geschlossenen, zylindrischen Filterpatronen von innen durch­ strömt. Die Filterpatrone besteht aus zwei konzentrischen, luftdurchlässigen (Gitter oder Lochbleche) Zylindern. Der Zwischenraum zwischen den Zylin­ dern ist meist mit Formkohle gefüllt. Auch hier wird wegen des Druckabfalls eine große Oberfläche bei geringer Dicke angestrebt. Ansonsten bleiben die anderen bekannten Nachteile der Schüttung bestehen: Bildung von Gassen, Aneinanderreiben der Teilchen, was zu Abrieb und Staub führt usw.In another embodiment, a series of parallel, cylindrical filter cartridges closed on one side from the inside flows. The filter cartridge consists of two concentric, air-permeable (Grid or perforated sheet) cylinders. The space between the zylin is usually filled with molded coal. Again, because of the pressure drop aiming for a large surface with a small thickness. Otherwise they stay there are other known disadvantages of the filling: formation of alleys, Rubbing the particles together, which leads to abrasion and dust, etc.

Es wurde versucht, in bestehenden Systemen mit Filterpatronen die Schüttung durch zylindrisch angeordnete Schaumplatten zu ersetzen. Wenngleich damit viele der Nachteile der Schüttung eliminiert wurden, so wurde doch nur ein Teilerfolg erzielt. Grund war, daß der Schaum durch das Krümmen der Platten zu Zylindern an der Innenseite zusammengestaucht wurde, was zu einer sehr erheblichen Erhöhung des Luftwiderstands führte.An attempt was made to fill the bed in existing systems with filter cartridges to be replaced by cylindrical foam sheets. Although with it Many of the disadvantages of the fill have been eliminated, so only one has been Partial success achieved. The reason was that the foam was caused by the curving of the plates was compressed into cylinders on the inside, which resulted in a very significant increase in air resistance.

Es war Ziel der vorliegenden Erfindung, eine Filterpatrone auf Schaumbasis mit der Luftdurchlässigkeit der flachen Platte zu schaffen.It was an object of the present invention to provide a foam-based filter cartridge to create with the air permeability of the flat plate.

Die erfindungsgemäße Lösung besteht darin, daß auf einer Seite des PU-Trä­ gerschaums in regelmäßigen Abständen Aussparungen angebracht werden, die das Zusammenstauchen an der Innenseite zum großen Teil aufheben. Der auszugleichende Unterschied zwischen äußerem und innerem Umfang beträgtThe solution according to the invention is that on one side of the PU-Trä cutouts are made at regular intervals, which largely cancel out the contraction on the inside. Of the difference to be compensated for between the outer and inner circumference

2 πR - 2 π (R-d) = 2 πd2πR - 2π (R-d) = 2πd

worin R der Radius des äußeren Umfangs und d die Dicke der Matte sind. Sind x Aussparungen vorhanden, so hat jede Aussparung an der Innenseite eine Breite von 2 π d/x. In der Praxis wird die Aussparung dreieckförmig sein und mindestens bis zur Mitte der Schaumschicht reichen. Sie wird eine etwas geringere Breite als 2 π d/x haben, um einen guten Zusammenschluß der Sei­ tenflächen sicherzustellen. Die damit erzielte Verbesserung der Luftdurchläs­ sigkeit wird an einem Beispiel demonstriert.where R is the radius of the outer circumference and d is the thickness of the mat. If there are x recesses, each recess has an inside a width of 2π d / x. In practice, the recess will be triangular  and reach at least to the middle of the foam layer. It becomes something have a width smaller than 2 π d / x to ensure a good connection of the screen area. The resulting improvement in air flow liquidity is demonstrated using an example.

Als Schäume können offenporige retikulierte PU-Schäume mit Dicke von 5- 40 mm, vorzugsweise 10-30 mm, und einer Porosität von 8-30 ppi verwen­ det werden. Das Litergewicht liegt üblicherweise um 30 g. Neben den in der DE 38 13 563 A1 erwähnten Haftmassen, wie Kunststoffdispersionen und präpolymere, maskierte Polyisocyanate, die mittels eines Diamins vernetzt werden, wurden sehr gute Ergebnisse mit Levacast Addukt 43 131 N der Bayer AG erzielt. Dieses Produkt wird als Beschichtungsmasse für die Kunst­ lederherstellung angeboten und vernetzt in Gegenwart von Feuchtigkeit. Ein bevorzugter Weg ist, die Feuchtigkeit mit dem Adsorbens einzubringen.Open-pore reticulated PU foams with a thickness of 5- Use 40 mm, preferably 10-30 mm, and a porosity of 8-30 ppi be det. The liter weight is usually around 30 g. In addition to those in the DE 38 13 563 A1 mentioned adhesive compositions, such as plastic dispersions and prepolymer, masked polyisocyanates that crosslink using a diamine very good results were obtained with Levacast adduct 43 131 N Bayer AG achieved. This product is used as a coating for art leather production offered and cross-linked in the presence of moisture. On the preferred way is to introduce the moisture with the adsorbent.

Als Adsorbenzien kommen neben Aktivkohlekügelchen auf Pechbasis oder hergestellt aus Polymeren, körnige Aktivkohlen, imprägnierte Aktivkohlen, Ze­ olithe, poröse Polymere usw. infrage, die dem Fachmann bekannt sind. Grundsätzlich ist die erfindungsgemäße Problemlösung vom Adsorbens un­ abhängig.In addition to activated carbon beads on pitch basis or come as adsorbents made from polymers, granular activated carbons, impregnated activated carbons, Ze olite, porous polymers, etc., which are known to the person skilled in the art. Basically, the problem solution of the adsorbent is un dependent.

Beispielexample

Eine 30 mm dicke Bahn aus einem offenporigen, retikuliertem Polyurethan­ schaum mit 22 ppi wurde im Abstand von ca. 45 mm mit 15 mm tiefen und 10 mm breiten Ausschnitten versehen, mit einer Haftmasse bestehend aus 1.000 Teilen Impranil HS 62 und 62 Teilen Imprafix HSC beaufschlagt und abge­ quetscht (Abquetscheffekt ca. 100%) und schließlich mit einer Kugelkohle (Pechbasis, ⌀ ca. 0,5 mm, 1100 m²/g) bestreut. Pro Liter Schaum wurden ca. 210 g Kohle aufgenommen. Nach Aushärten der Haftmasse wurde die Bahn in Streifen von 30 cm Breite geschnitten und daraus ein zylindrischer Filter mit einem äußeren Durchmesser von 480 mm hergestellt, wobei die Stöße ver­ klebt wurden. Durch das Zusammenstauchen an der Innenseite kommen die Aussparungen zum Verschwinden. Danach wurde durch die Wand des Zylin­ ders Luft mit einer mittleren radialen Geschwindigkeit von 1 m/s von innen nach außen geblasen und der Druckverlust beim Durchgang durch die Filter­ schicht gemessen: Er betrug 105 Pa.A 30 mm thick sheet made of an open-pore, reticulated polyurethane foam with 22 ppi was spaced approx. 45 mm with 15 mm deep and 10 mm wide cutouts, with an adhesive consisting of 1,000 Parts Impranil HS 62 and 62 parts Imprafix HSC acted on and removed squeezes (squeezing effect approx. 100%) and finally with a spherical carbon (Pitch base, ⌀ approx. 0.5 mm, 1100 m² / g) sprinkled. Approx. 210 g of coal added. After the adhesive had hardened, the web was closed in  Cut strips 30 cm wide and use them to create a cylindrical filter an outer diameter of 480 mm, the joints ver were stuck. By coming together on the inside they come Cutouts to disappear. After that, through the wall of the Zylin air with an average radial speed of 1 m / s from the inside blown out and the pressure loss when passing through the filter layer measured: It was 105 Pa.

In gleicher Weise wurde eine zylindrische Filterpatrone hergestellt, jedoch wurde diesmal die Schaumbahn nicht mit Aussparungen versehen. Der Druck­ verlust betrug in diesem Fall 146 Pa. Durch die Aussparungen hat sich die Kohlemenge um 45 g oder 15%, der Druckverlust jedoch um 28% erniedrigt, so daß ein Nettogewinn von 13% vorliegt. Durch die gleichmäßigere Nutzung der Kohle ist zudem eine höhere dynamische Kapazität zu erwarten.A cylindrical filter cartridge was made in the same way, however this time the foam sheet was not provided with recesses. The pressure in this case the loss was 146 Pa. Through the cutouts, the Amount of coal by 45 g or 15%, but the pressure drop is reduced by 28%, so there is a net profit of 13%. Through more even use coal is also expected to have a higher dynamic capacity.
