Abstract

The filter includes a flexible and permeable support (a) contg. or a adjacent to chemical sorption agents (b). The support (a) is pref. a fabric or cloth, either of which may be quilted, and esp. contg. waterproof materials, e.g. fibres or similar elements made of ceramics, glass, plastics or metals, and quilted like a mattress to form layers between which agents (b) are located. Different agents (b) may be used in the various layers. Agents (b) are pref. active carbon; and/or active coke; and/or CaCl2; and/or soda lime; and/or a catalyst for CO. The agents may be fixed in or on support (a) as a liq., e.g. NaOH soln.; or as powders; or on expanded granules of Ca-Al-silicate. The catalyst for CO is pref. 60% MnO2, 40% CuO; or 50% MnO2, 30% CuO, 15% cobalt oxide and 5% Ag2O. Air breathed by the driver and passengers is purified from noxious substances even in very dense traffic, etc.

Description

In der Patentanmeldung P 28 20 314.7 wird ein Filter für Autokabinen beschrieben, wobei der Filter aus filternden Stützgeweben und/oder übereinander gelagerten Fliesschichten besteht, mit dazwischen gelagerten Absorptionsmassen armiert ist und platten-kissenförmig zusammengefügt sein kann.In the patent application P 28 20 314.7 a filter for car cabins is described, wherein the filter consists of filtering support fabrics and / or superimposed flow layers, is reinforced with absorption masses between them and can be joined together in the form of a plate-cushion.

Um den beschriebenen Chemiesorptionsfilter für Autokabinen vereinfacht herstellen zu können, wird erfindungsgemäß vorgeschlagen, daß bei der Herstellung des Filtermaterials, z.B. Fliesfiltergewebe und/oder Nadelfilzgewebe, das Absorptionsmaterial direkt in das Gewebe mit eingearbeitet wird, und die absorbierenden Massen, wie z.B. Perlite, die mit Natronlauge getränkt ist und/oder z.B. mit Kalk und Kupferstaub ummantelt wird bzw. A-Kohle - insgesamt trockene und feuchte Massen - werden direkt und/oder zwischen den Lagen bei der Herstellung vorzugsweise in einem Arbeitsvorgang Verbindung finden.In order to be able to produce the described chemical sorption filter for car cabins in a simplified manner, it is proposed according to the invention that during the production of the filter material, for example fleece filter fabric and / or needle felt fabric, the absorbent material is incorporated directly into the fabric, and the absorbent masses, such as perlite, which with Caustic soda is soaked and / or coated with lime and copper dust, for example, or activated charcoal - a total of dry and moist masses - will be connected directly and / or between the layers during production, preferably in one work process.

In der beiliegenden Zeichnung ist eine Ausbildungsform dargestellt:The attached drawing shows one form of training:

mit 1 das Filtermaterial, z.B. Gewebeflies,with 1 the filter material, e.g. fabric fleece,

mit 2 die eingearbeiteten Absorptionsmassen.with 2 the incorporated absorption masses.

Es können selbstverständlich mehrere Schichten übereinander gelagert werden, die alle bei der Herstellung mit unterschiedlich eingearbeiteten Chemiesorptionsmassen versehen sind.It goes without saying that several layers can be stored one on top of the other, all of which are provided with differently incorporated chemical sorbent masses during manufacture.

So können z.B. zwei oder drei Schichten auf verschiedene Arten hergestellt sein, um dann als Paket zu einem Filter im Ansaugschacht einer Autokabine abdichtend eingelagert zu sein.For example, two or three layers can be produced in different ways, so that they can then be stored in a sealed package with a filter in the intake duct of a car cabin.
