Abstract

Purificn. of contaminated air, pref. air supplied to cabins accommodating people, using sorption and catalyst compsns., comprises first passing the air supplied to the filter and contaminated e.g. with SO2, NO2, NO and HC cpds., through a layer of soda-lime and then through a layer of catalyst, e.g. hopkalite, to effect partial oxidn. of the N oxides, pref. NO to NO2, and finally through an activated charcoal layer. After heating, it is passed through a second catalyst layer, e.g. hopkalite, to convert CO to CO2 and pref. cooled before entering the cabin. The process is specified for the purificn. of air supplied to the interior of vehicles. The process is simple and the sorption and catalyst compsns. are relatively stable.

Beschreibung und Erläuterung zur Zusatzpatentanmeldung Description and explanation of the additional patent application

'Chemisorptionsschichten-Anordnung in Arbeitsschutzkabinen' Zusatzanmeldung zu P 30 18 695.9 In der Hauptanmeldung P 30 18 695.9 wird ein Verfahren zur Verbesserung der Standzeit von Chemisorptionsmassen beschrieben. 'Arrangement of chemisorption layers in work safety cabins' additional registration to P 30 18 695.9 In the main application P 30 18 695.9 a method for improvement the service life of chemisorption materials.

Hier wird die anströmende und zu reinigende Luft entsprechend dem erfindungsgemäßen Gedanken so weit erhitzt, daß der Dampfdruck der zu reinigenden Luft oder Gase so weit heraufgesetzt wird, daß eine Feuchtigkeitsaufnahme in den Chemisorptionsmassen fast oder gänzlich verhindert wird.Here the incoming air to be cleaned is corresponding to the inventive thought heated so far that the vapor pressure of the to be cleaned Air or gases is increased so far that moisture absorption in the Chemisorptionsmassen is almost or completely prevented.

Der zusätzliche erfindungsgemäße Gedanke, der nachstehend ausgeführt wird, hat sich zur Aufgabe gestellt, daß die angesaugte, von Schadstoffen zu befreiende Luft zuerst in der vorhandenen natürlichen Temperatur durch Chemisorptionsfiltermassen geführt wird und hier von sauren Gasen, Kohlenwasserstoffen und festen Staubteilchen befreit wird und dann erst anschließend über eine Erwärmungsvorrichtung so weit aufgeheizt wird, daß der Wasserdampfdruck der Luft über dem Feuchtigkeitsaufnahmepunkt der nachgeschalteten Katalysatormassen zur Wandlung von CO in C02 ausreicht und die nach dem Durchfließen der Katalysatormassen von Schadstoffen befreite Luft einer Kühlzone zugeführt wird, die so weit die Luft abkühlt, wie es zur Humanisierung des Arbeitsplatzes, z.B. Arbeitsschutz- oder Fahrzeug-Kabine, dienlich ist.The additional inventive idea set forth below is, has set itself the task that the sucked, to be freed from pollutants Air first at the available natural temperature through chemisorption filter media and here by acid gases, hydrocarbons and solid dust particles is released and only then afterwards through a heating device so far is heated that the water vapor pressure of the air is above the moisture absorption point the downstream catalyst masses for Conversion of CO into C02 sufficient and which after flowing through the catalyst mass freed of pollutants Air is supplied to a cooling zone, which cools the air as far as it is necessary for humanization of the workplace, e.g. safety cabin or vehicle cabin, is useful.

Erfindungsgemäß wird die von Schadstoffen zu befreiende Atemluft für die Arbeitsschutzkabine zuerst über eine Natronkalkschicht geleitet zur vorzugsweisen Absorption von S02, SO und N02.According to the invention, the air to be freed of pollutants is for the work safety cabin is first passed over a layer of soda lime to the preferred Absorption of SO2, SO and N02.

Als zweite Schicht ist dahinter eine Katalysatorschicht angeordnet, bestehend aus Hopkalit, um das von der Natronkalkschicht nicht absorbierte NO in N02 zu wandeln, das dann von der dritten Schicht, einer A-Kohle-Schicht, zusätzlich mit den HC-Verbindungen adsorbiert wird.A catalyst layer is arranged behind it as the second layer, Consists of hopcalite to absorb the NO not absorbed by the soda lime layer in N02 to be converted by the third layer, an activated carbon layer, in addition is adsorbed with the HC compounds.

Hinter dieser A-Kohle-Schicht erfolgt dann die vierte Schicht, die aus einem Katalysator besteht, der CO in C02 wandelt, und hier wird die Luft vor dem Durchfließen dieser Kalatysatorschicht, die vorzugsweise aus Hopkalit besteht, erwärmt, so daß die Luft, ohne Feuchtigkeit auf dem Katalysator, z.B. Hopkalit, zu hinterlassen, gereinigt LeerseiteThe fourth layer, the consists of a catalyst that converts CO into C02, and this is where the air comes in before the flow through this Kalatysatorschicht, which preferably consists of hopcalite, heated so that the air, without moisture on the catalyst, e.g. hopcalite, to leave behind, cleaned Blank page
