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

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

'Rohrförmiger Autofilter für Personenschutz in Kraftfahrzeugen' Es ist bekannt und vielfach in der Literatur beschrieben worden, daß in Ansaugkanälen von Kraftfahrzeugen Filter zum Abscheiden von Staub oder gefährlichen Schadstoffen, wie NOx, Kohlenwasserstoffen und Co, eingebaut werden könnten.'Tubular car filter for personal protection in motor vehicles' Es is known and has been described many times in the literature that in intake ducts Filters of motor vehicles to separate dust or dangerous pollutants, such as NOx, hydrocarbons and Co, could be incorporated.

Obwohl es bekannt ist, daß Autoabgase stark gesundheitsgefährdend sind, hat sich der Einbau von filternden Elementen in Autoansaugkanälen nicht durchgesetzt.Although it is known that car exhaust fumes are highly hazardous to health the installation of filtering elements in car intake ducts has not caught on.

Der Aufwand für den Einbau war zu aufwendig, da eine große Filterfläche angeboten werden muß, um die Schadstoffe zu absorbieren.The effort for the installation was too expensive because of the large filter area must be offered to absorb the pollutants.

Um den Aufwand auf ein Minimum zu begrenzen und trotzdem eine sehr große Filterfläche, die mit Chemisorptionsmassen gefüllt ist, anzubieten, wird erfindungsgemäß folgende Vorrichtung vorgeschlagen.To keep the effort to a minimum and still a lot To offer a large filter surface which is filled with chemisorption masses is according to the invention proposed the following device.

In der beiliegenden Zeichnung ist in der Abbildung A schematisch folgendes dargestellt: mit 1 die rohe Luft mit 2 ein Ansaugrohr oder Ansaugschlauch mit 3 ein Chemisorptionsfilter mit 4 der Ventilator, der auf der Saugseite und/oder auf der Druckseite im Ansaugrohr oder im Blasrohr oder Blasschlauch ebenfalls mit 3 und/oder 5, einem Chemisorptionsfilter, in Verbindung steht, mit 5 der blasseitige Chemisorptionsfilter mit 6 ein Ausblasrohr oder Ausblasschlauch mit 7 die Reinluft, die zu den Belüftungsschlitzen im Wageninneren führt Abbildung B: mit 2/6 das Ansaugrohr, der Ansaugschlauch bzw. das Blasrohr oder der Blasschlauch mit 3/5 das Chemisorptionsfilter, das erfindungsgemäß eine geschlossene, rohrförmige Körperform aufweist, wobei die Körperform als Profilform ausgebildet ist, und die Profile selber, mit 8 bezeichnet, mit Chemisorptionsmassen gefüllt sind, so daß eine große, aktive Oberfläche zur Chemisorption der Schadstoffe zur Verfügung steht.In the accompanying drawing, Figure A shows schematically the following shown: with 1 the raw air with 2 a suction pipe or suction hose with 3 a chemisorption filter with 4 the fan that is on the suction side and / or on the pressure side in the suction pipe or in the blow pipe or blow hose also with 3 and / or 5, a chemisorption filter, is in connection, with 5 the blower side Chemisorption filter with 6 an exhaust pipe or an exhaust hose with 7 the clean air, which leads to the ventilation slots inside the car Figure B: with 2/6 the suction pipe, the suction hose or the blow pipe or the blow hose with 3/5 the chemisorption filter, which according to the invention is a closed, tubular Has body shape, wherein the body shape is designed as a profile shape, and the Profiles themselves, labeled 8, are filled with chemisorption masses, so that a large, active surface is available for chemisorption of the pollutants.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen und gezeichneten Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, im Ansaug- oder im Druckbereich einer Autokabinenbelüftung Chemisorptionsfilter einzusetzen, die einen rohrförmigen Charakter aufweisen und als Rohrprofil profilierte Kammern 8 aufweisen, in die die chemisorbierenden Massen eingelagert werden.Of course, the invention is not limited to the above in detail The forms of training described and drawn are limited, but there are numerous Changes possible without deviating from the basic idea of the intake or to use chemisorption filters in the pressure area of a car cabin ventilation system, which have a tubular character and chambers profiled as a tubular profile 8 have, in which the chemisorbent masses are incorporated.
