Abstract

A method of purifying air to be fed into a protected working zone or automobile cabin utilizes a filter consisting of a permeable support on/in which chemical absorption materials and/or catalysts are laid. The incoming air is entirely or partly heated before it reaches the filters. When the appts. is in use, the normal fresh air inlet ducts of an automobile are closed and the ventilator fan is converted for use as a pure circulating fan recycling the entire air content of the vehicle. In addn., a separate ventilator fan draws in air and expels it at above-atmospheric pressure into the circuit via the chemical absorption filter. A corresponding quantity of air escapes from the circuit to atmosphere. In particular for automobiles in traffic jams or smog conditions as a substitute for conventional ventilation. By heating the air before it reaches the chemical absorption filter, moisture in the air is prevented from precipitating. Precipitation of moisture has a very adverse effect upon the effect of chemical absorption agents and catalysts. Thus the efficiency of the plant is greatly improved.

-Hilfsaebrauchsmusteranmeldung 'Verfahren und Vorrichtung zur Abscheidung von Schadstoffen aus der Luft, die zur Belüftung von Earlrzeua- oer Arbeitsschutzkabinen dienen soll' In der Hauptanmeldung wird ein Verfahren und eine Vorrichtuno beschrieben, in der auf der Luftanströmseite die zu reinigende Luft und/oder die Chemisorptionsmassen erfordernisoerecht mittels Heizaggregat aufgeheizt werden, wobe gleichzeitiq die Kühlleistung des Heizagqreqates auf der Abströmseite genutzt wird und die gereinigte Luft kühlt.- Auxiliary utility model registration 'Process and device for deposition of pollutants from the air that are used to ventilate Earlrzeua- oer work safety cabins should serve 'In the main application a method and a device is described, in the air to be cleaned and / or the chemisorption masses on the air inflow side are properly heated by means of a heating unit, whereby at the same time the The cooling capacity of the heating unit on the downstream side is used and the cleaned Air cools.

Um die Heizleistung nicht zu hoch wählen zu müssen, wird erfindungsgemäß vorgeschlagen, wie nachstehend beschrieben und in der Vorrichtung dargestellt, Qß nur die Luft bzw.In order not to have to choose the heating output too high, according to the invention proposed as described below and illustrated in the device, Qβ only the air resp.

die Massen aufgeheizt werden, die katalytisch CO in C02 wandeln sollen.the masses are heated up, which are to catalytically convert CO into C02.

Dieses ist in der beilieqenden Zeichnung erfindungsgemäß dargestellt; mit 1 die Anströmseite der schadstoffbeinhaltenden Luft mit 2 Chemisorptionsmassen zur Abscheidung von sauren Gasen, wie z. B. S02, NOx, Kohlenwasserstoff und auch feste staubförmige Schadstoffe, mit 3 der Kanal oder die Auffanoräumlichkeit des vorgereinigten Gases, das der Aufheizfläche (4), z. B. aufgeheizten Rippen, zugeführt wird, mit 4 die Aufheizflächen mit 5 die Katalysatorschicht bzw. Hopkalitschicht, die CO in C02 wandeln soll, mit 6 die gereinigte, atembare Luft, die noch aufgeheizt den Kühlrippen (7) zur Abkühlung und zur späteren Verwendung als Atemluft zugeführt wird, mit 7 die Kühlrippen mit 8 die kombinierten wärme-kälte-erzeugenden Aggregate, die auf der einen Seite die vorgereinigte Luft über die Aufheizfläche (4) aufheizen und auf der anderen Seite mit ihrer Kühlwirkung die Kühlrippen (7) kühlen.This is shown according to the invention in the accompanying drawing; with 1 the upstream side of the pollutant-containing air with 2 chemisorption masses Separation of acidic gases, such as B. S02, NOx, hydrocarbon and also solid dusty pollutants, with 3 the sewer or the Auffanoräumlichkeit of the pre-cleaned Gas that the heating surface (4), z. B. heated ribs, is supplied with 4 the heating surfaces with 5 the catalyst layer or hopcalite layer, the CO in C02 is supposed to convert, with 6 the purified, breathable air, which still heats up the cooling fins (7) is supplied for cooling and for later use as breathing air, with 7 the cooling fins with 8 the combined heat-cold-generating units that on on the one hand, heat the pre-cleaned air over the heating surface (4) and on the other hand, their cooling effect cools the cooling fins (7).

Vorzugsweise nimmt man hierfür bekannte Pelletierelemente, die die erfindungsgemäße Aufgabenstellung hier erfüllen können.It is preferred to use known pelletizing elements for this purpose, which the can fulfill the task according to the invention here.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellten und beschriebenen Vorrichtungen beschränkt, sondern es sind zahlreiche Abanderunqen möglich, ohne jedoch von dem verfahrenstechnischen Grundgedanken abzuweichen, daß die angesaugte, mit Schadstoffen belastete Luft zuerst durch Chemisorptionsmassen gedrückt oder gesaugt wird und hier von sauren Gasen, festen Stoffen und Kohlenwasserstoffen befreit wird, um anschließend soweit erwärmt zu werden, daß der Wasserdampfdruck der Luft über dem Feuchtigkeitsaufnahmepunkt des Katalysators liegt und anschließend die Luft über die Kühl leistung der erwärmenden Aggregate und/oder auch durch zusätzliche Kühlaggregate bedarfsgerecht soweit heruntergekühlt wird, daß z. B. für den Sommerbetrieb dieses Aggregat nicht nur als Chemisorptionsfilter, sondern auch gleichzeitig als Klimaanlage für Arbeitsschutz- oder Fahrerkabinen genutzt werden kann.Of course, the invention is not limited to the above in detail shown and described devices are limited, but there are numerous Modifications possible without deviating from the basic procedural concept, that the air that is sucked in and contaminated with pollutants is first passed through chemisorption masses is pressed or sucked in and here by acid gases, solid substances and hydrocarbons is released in order to then be heated to such an extent that the water vapor pressure the air is above the moisture absorption point of the catalyst and then the air through the cooling capacity of the heating units and / or through additional ones Cooling units are cooled down as needed so that z. B. for summer operation this aggregate not only as a chemisorption filter, but also as a Air conditioning can be used for occupational safety or driver's cabs.

Die Luft wird vorzugsweise auf um SO 0C aufgeheizt, um beim Durchfließen des Katalysators diesen nicht durch Feuchtigkeitsaufnahme inaktiv werden zu lassen.The air is preferably heated to around SO 0C in order to flow through of the catalyst so that it does not become inactive due to moisture absorption.
