Abstract

The layers of chemisorbtive and catalytic material in a filter for supplying purified air to a vehicle interior are sepd. from a dryin filter layer by a heater supplied from the vehicle's electrical system. This ensures that only a small quantity of very hot air is utilised to expel the collected moisture which is expelled by a fan into the atmos. Appreciably less regenerated air the fresh air is used to ventilate the interior. During regeneration sec. air is entrained with the hot prim. air, and the resulting lower temp. protects the fan. Primarily for use in congested traffic, when both noxious gases and moisture are adsorbed. During subsequent less contaminated travel the filter is regenerated. The appts. only heats the moisture-adsorbing layer, so reducing power consumption, while the other layers are regenerated by cooler air.

Description

Beschreibung und Erläuterung zur Zusatzpatent-Description and explanation of the additional patent

anmeldung Chemiesorptionsfilter für die Frischluftzuführung in Fahrzeugkabinen mit Regenerierungs vorrichtung und Kühlluftzuführung für den Ventilator' Zusatz zu P 29 50 179.9 In der Hauptanmeldung P 29 50 179.9 wird die Belüftung von Autokabinen beschrieben.registration chemical sorption filter for the fresh air supply in vehicle cabins with regeneration device and cooling air supply for the fan 'add-on to P 29 50 179.9 In the main application P 29 50 179.9 the ventilation of car cabins described.

Das besondere Merkmal der Belüftung ist die Vorschaltung eines Chemiesorptionsfilters bei Staufahrten, so daß die angesaugte Luftmenge zwangsläufig von Schadstoffen wie CO, HC und NOx befreit und dem Passagierraum zugeführt wird.The special feature of the ventilation is the upstream connection of a chemical sorption filter in traffic jams, so that the amount of air sucked in is inevitably of pollutants such as CO, HC and NOx released and fed to the passenger compartment.

Bei Nicht-Staufahrt kann der Chemiesorptionsfilter ausgeschaltet werden, und die normale Belüftung nach dem Stand der Technik, wie er bisher bekannt ist, übernimmt die Funktion der Frischluftzuführung für die Fahrzeugkabine.When not in a traffic jam, the chemical sorption filter can be switched off, and normal ventilation according to the state of the art as it is known so far, takes over the function of supplying fresh air to the vehicle cabin.

Weiterhin ist beschrieben, daß während der Zeit der normalen Belüftung ohne vorgeschalteten Chemiesorptionsfilter eine wunschgerechte Spülluftmenge aufgewärmt den Chemiesorptionsfilter regeneriert und von Feuchtigkeit befreien kann.It is also described that during the period of normal ventilation without an upstream chemical sorption filter, the required amount of purge air is warmed up regenerates the chemical sorption filter and frees it from moisture.

Die gesamte Aufheizung der Chemiesorptionsmassen bedeutet naturgemäß einen relativ hohen Energieaufwand, der in den normalen Kraftfahrzeugen aufgrund der Elektroinstallation und der Batterieanlage nicht langfristig gewährleistet werden kann.The entire heating up of the chemical sorption masses means naturally a relatively high energy consumption, which is due to normal motor vehicles the electrical installation and the battery system cannot be guaranteed in the long term can.

Aus diesem Grunde wird vorgeschlagen, daß eine vorgeschaltete Feuchtigkeitsaufnahmeschicht allein regeneriert wird und nur eine geringe Luftmenge sehr hoch aufgeheizt die Feuchtigkeit austreibt und über den Ventilator ins Freie bläst.For this reason it is proposed that an upstream moisture absorption layer is regenerated alone and only a small amount of air is heated to a very high level Drives out moisture and blows it outside via the fan.

Damit der Ventilator die hohen Temperaturen übersteht, wird weiterhin erfindungsgemäß vorgeschlagen, den Ventilator so auszubilden, daß er bei der Regenerationsfahrt Sekundärluft zu der heißen Primärluft ansaugt und soweit beim Durchspülen des Ventilators die Luft herabkühlt, daß dieser keinen Schaden erleidet.In order for the fan to withstand the high temperatures, will continue proposed according to the invention to design the fan so that it is during the regeneration run Secondary air is sucked in to the hot primary air and so far when flushing the fan cools the air down so that it does not suffer any damage.

In der beiliegenden Zeichnung ist die erfindungsgemäße Ausführung dargestellt: mit 1 der komplette Chemiesorptionsfilter mit 2 die Mehrlagenchemiesorptionsmassen mit 3 die den Chemiesorptionsmassen vorgelagerte Trocknungsschicht, die zur Feuchtigkeitsaufnahme dient mit 4 der reversierbare Ventilator, der mehr Luft in den Chemiesorptionsfilter hineindrückt als er zurücksaugt mit 5 die große Luftmenge, die durch den Chemiesorptionsfilter zur Belüftung der Fahrzeugkabine hindurchgedrückt wird mit 6 die wesentlich kleinere Luftmenge, die aus der Fahrzeugkabine angesaugt und über eine Heizvorrichtung, vorzugsweise Heizspirale 8, stark aufgeheizt wird, so daß sie die Feuchtigkeit aus der Trocknungsschicht 3 in den Ventilator 4 abführt, der gesteuert über 7 eine Kühlluftmenge mit ansaugt, so daß der Ventilator nicht zu heiß wird.The embodiment according to the invention is shown in the accompanying drawing shown: with 1 the complete chemical sorption filter with 2 the Multi-layer chemical sorption materials with 3 upstream of the chemical sorption materials Drying layer, which serves to absorb moisture with 4 the reversible fan, that pushes more air into the chemical sorption filter than it sucks back with 5 the large amount of air that passes through the chemical sorption filter to ventilate the vehicle cabin With 6, the much smaller amount of air that comes out of the vehicle cabin is pushed through sucked in and strongly heated by a heating device, preferably heating coil 8 so that it will remove the moisture from the drying layer 3 in the fan 4 discharges, which, controlled by 7, sucks in a quantity of cooling air, so that the fan doesn't get too hot.

Durch die erfindungsgemäße Ausführung einer vorgeschalteten Trocknungsschicht, die separat durch eine Heizspirale, die aus der Batterie und/oder aus der Lichtmaschine direkt gespeist wird, beheizt wird, ist die Gewähr gegeben, daß mit geringer Heizleistung nur die vorgeschaltete Gastrocknungsschicht regeneriert wird und die Chemiesorptionsmassen bzw. Katalysatormassen 2 nicht hoch aufgeheizt werden müssen, um die durchzusaugende Regenerierungsluftmenge 6 soweit aufzuwärmen, daß sie zur Regeneration der Trocknungsschicht 3 genügend hoch,z. B. auf über 900, aufgeheizt ist.The inventive design of an upstream drying layer, which are separated by a heating coil that comes from the battery and / or from the alternator is fed directly, is heated, there is a guarantee that with low heating power only the upstream gas drying layer is regenerated and the chemical sorption masses respectively. Catalyst masses 2 do not have to be heated to a high level in order to suck through the Regeneration air quantity 6 to warm up to the point that it is used to regenerate the drying layer 3 sufficiently high, e.g. B. to over 900 is heated.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen und dargestellten Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, einen Chemiesorptionsfilter zur Belüftung von Autokabinen so herzustellen, daß er mit einer separaten Trocknungsschicht 3, die den eigentlichen Chemiesorptions- und Katalysatormassen vorgeschaltet ist, versehen ist, wobei die Heizspirale 8 einmal zum wunschgerechten Anwärmen der angesaugten Frischluft z. B. auf 20 oder 300 dient und beim Rückwärtslauf des Ventilators 4 die wenige Luft zur Regenerierungsphase derart stark aufheizt, daß die Feuchte ausgetrieben wird und somit noch genügend Feuchte in den Chemiesorptionsmassen zur Sorption der Schadstoffe zur Verfügung steht.Of course, the invention is not limited to the above in detail training forms described and illustrated are limited, but there are numerous Modifications possible without deviating from the basic idea, a chemical sorption filter for ventilation of car cabins so that it is covered with a separate drying layer 3, which is upstream of the actual chemical sorption and catalyst masses, is provided, the heating coil 8 once for the desired heating of the sucked in Fresh air z. B. is used on 20 or 300 and when the fan is running backwards 4 the little air for the regeneration phase heats up so much that the moisture is expelled and thus still sufficient moisture in the chemical sorption masses for sorption of the Pollutants is available.
