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.

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

'Verfahren zur Verbesserung der Standzeit von Chemisorptionsmassen, vorzugsweise in Fahrzeug-und Arbeitsschutz-Kabinen' Es ist bekannt, in Fahrzeugen oder Kabinenschutz-Filtern CO durch Hopkalitmassen abzuscheiden; jedoch beim Durchfließen der Luftmassen, die mit CO angereichert sind, nimmt das Hopkalit im Regelfall durch die vorbeistreifende Luft Feuchtigkeit auf.'' Process to improve the service life of chemisorption compounds, preferably in vehicle and occupational safety cabins' It is known in vehicles or cabin protection filters to separate CO through hopcalite masses; but when flowing through of the air masses that are enriched with CO, the hopcalite usually takes through the passing air absorbs moisture.

Diese Feuchtigkeitsaufnahme führt zur Zerstörung der Abscheidefähigkeit des Hopkalit.This absorption of moisture leads to the destruction of the separability of the hopcalite.

Um das Hopkalit aktiv zu halten, vorzugsweise für das Abscheiden von CO bei der Suftzuführung in Räumen, in denen Menschen arbeiten, wird erfindungsgemäß vorgeschlagen, daß der Wasserdampfdruck der Luft über den Feuchtigkeitsaufnahmepunkt des Hopkalit und somit der Absorptionsschicht gelegt wird und oder der übrigen noch zusätzlich eingebrachten Chemisorptionsschichten, z.B. zur Beseitigung von NOx und HC-Verbindungen.To keep the hopcalite active, preferably for the deposition of According to the invention, CO is used for supplying air to rooms in which people work suggested that the water vapor pressure of the air is above the moisture absorption point of the hopcalite and thus the absorption layer is placed and or the rest of it additionally introduced chemisorption layers, e.g. to remove NOx and HC connections.

Dieses wird erfindungsgemäß dadurch erreicht, daß man die Chemisorptionsmassen, z.B. Hopkalit, so stark aufwärmt, daß der beschriebene gewünschte Effekt eintritt. Dieser Effekt wird z.B. für bestimmte Massen-Zusammensetzungen erreicht bei ca. 500C.This is achieved according to the invention in that the chemisorption masses, e.g. Hopcalite, warms up so much that the desired effect described occurs. This effect is used e.g. for certain Mass compositions achieved at about 500C.

Durch diese Maßnahme würde naturgemäß die angesaugte Luft derart aufgeheizt, daß die zu schützenden Menschen sehr stark durch hohe Lufttemperaturen belastet würden.This measure would naturally heat the sucked-in air in such a way that that the people to be protected are very heavily burdened by high air temperatures would.

Um diese zu vermeiden, wird erfindungsgemäß weiterhin vorgeschlagen, daß das Verfahren 'Aufwärmen der Chemisorptionsmassen' so ausgeführt ist, daß die Vorrichtung zur Erwärmung der Chemisorptionsmassen so im Verfahren eingebaut ist, daß die anströmende, zu reinigende Luft allein und oder mit den Chemisorptionsmassen durch das Aggregat erwärmt wird und die aufströmende Luft durch die erzeugte Kälteleistung des Aggregats wieder abgekühlt wird durch den sich einstellenden Wirkungsgrad von z.B. 500C auf 50°C.In order to avoid this, it is further proposed according to the invention that that the process 'warming up the chemisorption masses' is carried out so that the Device for heating the chemisorption masses is built into the process in such a way that that the incoming air to be cleaned alone and or with the chemisorption masses is heated by the unit and the air flowing up through the generated cooling capacity of the unit is cooled down again due to the efficiency of e.g. 500C to 50 ° C.

Durch dieses erfindungsgemäße Verfahren ist die Gewähr gegeben, daß die Chemisorptionsmassen gegenüber dem bekannten Stand der Technik eine zig-fach höhere Standzeit aufweisen und andererseits die von Schadstoffen befreite Luft mit niedriger Temperatur wieder in den Kreislauf gelangt.This inventive method ensures that the chemisorption materials tens of times compared to the known prior art have a longer service life and, on the other hand, the air that has been freed of pollutants low temperature is returned to the circuit.

In der beiliegenden Zeichnung ist die erfindungsgemäße Ausführung dargestellt: mit 1 die anströmende Luft mit 2 das Chemisorptionspaket mit 3 die dem Chemisorptionspaket vorgelagerte Erwärmungs- und Kühlvorrichtung, vorzugsweise als Peltierelement ausgebildet mit 4 die auf das Peltierelement aufgesetzten Kühlrippen im Abluftkanal mit 5 die auf das Peltierelement aufgesetzten Aufheizrippen im Zuluftkanal mit 6 der Abluftkanal.The embodiment according to the invention is shown in the accompanying drawing shown: with 1 the incoming air with 2 the chemisorption package with 3 the Heating and cooling device upstream of the chemisorption package, preferably designed as a Peltier element with 4 cooling fins placed on the Peltier element in the exhaust air duct with 5 the heating ribs placed on the Peltier element in the supply air duct with 6 the exhaust duct.
