Abstract

It is known to use circulated air filters having activated charcoal nonwoven fabric mats, activated charcoal fillings and UV lamps. In order for this circulation filter method not only to be effective in terms of separating off dust and odour, but also to the effect that it separates off acidic gaseous pollutants and at the same time has a bactericidal action, even without a UV lamp, according to the invention the combination of a filter made of a nonwoven dust separation fabric, an activated charcoal layer and a soda lime layer is proposed. The soda lime layer can also be placed upstream of the dust filter or between the individual layers of the same.

Description

Beschreibung und Erläuterung zur Patent- undDescription and explanation of the patent and

Hilfagebrauchsmusteranmeldung "Umluftfilter vorzugsweise für Busfahrzeuge und Räume' i ist bekannt, Umluftfilter mit A-Kohle-Fileßmatten, A-Bohle-Fütterungen und UV-Lampen zu verwenden.Utility model registration "Recirculating air filter, preferably for bus vehicles And rooms are known, circulating air filters with charcoal filing mats, A-plank linings and use UV lamps.

Erfindungsgemäß soll diese Umluftfiltertechnik nicht nur staub- und geruchsabscheidend sein, sondern sie soll auch saure, gasförmige Schadstoffe abscheiden und gleichzeitig bakterizid auch ohne UV-Lampe wirken.According to the invention, this recirculation filter technology should not only be dust and Be odor-separating, but it should also separate acidic, gaseous pollutants and at the same time have a bactericidal effect even without a UV lamp.

Hier setzt der erfindungsgemaße Gedanke ein, indem in an sich bekannter Weise Grob- und Feinstaubfilter mit Ak-tivkohlefiitterungen gepaart und mit einer erfindurgsgemäß nachgeschalteten Natronkalkschicht kombiniert werden.This is where the idea according to the invention comes in, in that it is known per se Coarse and fine dust filters are paired with activated carbon filters and with a According to the invention downstream soda lime layer are combined.

Natürlich kann die Natronkalkschicht auch den Staubfilter vorgesetzt werden oder zwischen den einzelnen Schichten angesetzt werden.Of course, the soda lime layer can also be placed in front of the dust filter or between the individual layers.

Selbstverständlich ist die Erfindun nicht auf die vorstehend in einzelnen dargestellter Ausbildunsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, die derzeit häufigsten Überscheitungen, insbesondere im Bereich NOX, höchstmöglich abzuscheiden und gleichzeitig noch eine bakterizide Wirkung zu erzeugen, indem erfindungsgemäß Natronkalk in Form einer Schichtung oder einer Einbindung in Fließstoff-Filten und dergleichen angewandt wird.Of course, the invention is not limited to the above in detail The forms of training shown are limited, but there are numerous changes possible, without deviating from the basic idea, the currently most frequent transgressions, especially in the area of NOX, to be separated as much as possible and at the same time one more Generate bactericidal effect by using soda lime according to the invention in the form of a Layering or incorporation in non-woven filters and the like applied will.
