Abstract

Apparatus for separating out dusts, acidic, gaseous constituents, odours and bacterial pollution. The invention relates to a ventilation filter, preferably for buses and rooms, which is provided with an activated charcoal layer and a dust-separating nonwoven web filter layer, where, in addition, a soda lime layer has additionally been used. In order to further improve such a ventilation filter, according to the invention it is proposed that a filter package layering (1) is used, which is composed on the inlet side of a dust separation filter (2) made of a nonwoven web filter material, a downstream soda lime layer (3), an activated charcoal layer (4) downstream of this and the layer of soda lime (5) downstream again and then a downstream layer (6) as a dust separation filter layer. This layering can also be repeated. <IMAGE>

Description

Beschreibung und Erläuterung zur ZusatzpatentanmeldungDescription and explanation of the additional patent application

'Mehrschichtiger Umluftfilter, vorzugsweise für Fahrzeugkabinen und Arbeitsschutzräume' Zusatz zu P 34 21 320.1 In der Hauptanmeldung P 34 21 320.1 wird ein Umluftfilter, vorzugsweise für Busfahrzeuge und Räume beschrieben, in dem eine A-Kohle-Schicht vorzugsweise einer staubabscheidenden Fließfilterschicht nachgeschaltet ist und zusätzlich eine Natronkalkschicht Anwendung findet.'' Multi-layer circulating air filter, preferably for vehicle cabins and Work protection rooms' Addition to P 34 21 320.1 In the main application P 34 21 320.1 describes a circulating air filter, preferably for bus vehicles and rooms, in which an activated carbon layer, preferably downstream of a dust-separating flow filter layer and a layer of soda lime is also used.

Erfindungsgemäß wurde befunden, daß es zweckdienlich ist, eine Filterkombination entsprechend beiliegender Zeichnung auszuführen, In der beiliegenden Zeichnung ist dargestellt: mit 1 eine komplette, kombinierte Filtermaschenschichtung, mit 2 z.B. die Anströmseite, die mit einer staubfilternden Fließschicht versehen wird, mit 3 eine Natronkalkschicht, mit 4 eine A-Kohle-Schicht, mit 5 eine Natronkalkschicht, mit 6 eine Fließfilterschicht.According to the invention it has been found useful to use a filter combination to be carried out according to the accompanying drawing, in the accompanying drawing shown: with 1 a complete, combined filter mesh layer, with 2 e.g. the upstream side, which is provided with a dust-filtering flow layer, with 3 a soda lime layer, with 4 an activated carbon layer, with 5 one Soda lime layer, with 6 a flow filter layer.

Durch diese erfindungsgemäße Anordnung wird erreicht, wie auch Messungen der Gutachter bestätigen, daß bakterienvolle Keime usw. bis zu über 80 °S abgeschieden werden, ohne W-Bestrahlung, und weiterhin durch die Natronkalkschicht zusätzlich auf der Anström- und Abströmseite eine ab- und/oder adsorptive, bakterizide Wirkung erzielt wird.As a result of this arrangement according to the invention, measurements are also achieved the expert confirms that germs full of bacteria etc. are deposited up to over 80 ° S without UV irradiation, and additionally through the soda lime layer an outflow and / or adsorptive, bactericidal effect on the inflow and outflow side is achieved.

Natronkalk auf der Anströmseite bindet fernerhin sämtliche anströmenden, sauren Bestandteile wie S02, HGl, HF usw.; die nachgeschaltete A-Kohle-Schicht bindet die Kohlenwasserstoffe und auch einen Teil NO und ist durch die Vorschicht geschützt gegen saure Bestandteile, damit die HC-Verbindungen optimal absorbiert werden.Soda lime on the inflow side also binds all inflowing, acidic components such as SO2, HGl, HF, etc .; the downstream activated carbon layer binds the hydrocarbons and also a part of NO and is protected by the pre-layer against acidic components so that the HC compounds are optimally absorbed.

Die A-Kohle-Schicht bindet natürlich auch Restbestandteile, die durch die Anströmfläche vom Natronkalk nicht aufgenommen werden - im Bereich von S02, HC1, HF usw.The activated charcoal layer naturally also binds residual components through the inflow surface is not absorbed by the soda lime - in the area of S02, HC1, HF etc.

Wesentlich ist hierbei, daß das NO wieder zu N02 gebildet wIrd, - durch die A-Kohle kann sich N02 bilden -das wird anschließend durch die nachgesetzte Natronkalkschicht wieder aufgenommen.It is essential that the NO is formed back to N02, N02 can form through the activated carbon - this is then caused by the subsequent one Soda lime layer resumed.

Die Natronkalkschicht absorbiert praktisch das in der A-Kohle-Schicht gewandelte N02. Die Gefährlich~ keit des NO ist hiermit gemindert, da die Aufoxidation zu NO2 durch die Natronkalkschicht eliminiert wird.The soda lime layer practically absorbs that in the activated carbon layer converted N02. The danger of NO is thereby reduced, since the overoxidation to NO2 is eliminated by the soda lime layer.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellten und beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, die Anordnung der einzelnen Schichten ein- oder mehrfach in der Reihenfolge, wie dargestellt, anzuwenden, um gefährliche, saure Bestandteile und bakterielle Bestandteile aus der angesaugten Atemluft zu entfernen.Of course, the invention is not limited to the above in detail Forms of training shown and described are limited, but there are numerous Changes possible without deviating from the basic idea, the arrangement of the individual layers one or more times in the order as shown, apply to hazardous, acidic components and bacterial components to remove the aspirated breath.
