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

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

und Hilfsgebrauchsmusteranmeldung Autofilter mit Sekundärluftzuführung für die Regenerierung des Chemisorptions- und Katalysatorfilters' In der genannten Anmeldung wird ein Filter zur Reinigung der Luft, die in Autokabinen eingeblasen wird, beschrieben, wobei gleichzeitig eine Vorrichtung vorgesehen ist, die die Regenerierung der Chemi- und Katalysatormassen bewirkt.and utility model registration for car filters with secondary air supply for the regeneration of the chemisorption and catalyst filter 'In said Registration will use a filter to purify the air that is blown into car cabins is described, at the same time a device is provided that the regeneration the chemical and catalyst compounds.

Der Filter ist mit einer separaten Trocknungsschicht versehen, die den eigentlichen Chemi- und Katalysatornassen vorgeschaltet ist, und besitzt zusätzlich eine Heizeinrichtung, die a) zum wunschgerechten Anwärmen der angesaugten Frisch~ luft und h) beim Riickwärtslauf des Ventilators zur Regenerierunq der Trocknungsmasse dient.The filter is provided with a separate drying layer that is upstream of the actual chemical and catalyst wet, and also has a heating device that a) for the desired warming of the freshly sucked in air and h) when the fan rotates backwards to regenerate the drying mass serves.

Um während der Regenerierungsphase nicht die feuchte Luft aus der Fahrzeugkabine über die Chemisorptions-und Katalysatormassen ansaugen zu müssen, die zur Aufwärmung und anschließenden Regeneration der Trocknungsschicht dienen soll, wird erfindungsgemäß vorgeschlagen, das Ikutofiltersystem wie folgt anzuordnen.In order not to remove the moist air from the during the regeneration phase Having to suck in the vehicle cabin through the chemisorption and catalyst masses, which serve to warm up and subsequent regeneration of the drying layer is, it is proposed according to the invention to arrange the ICUTO filter system as follows.

In der beiliegenden Zeichnung ist dargestellt: mit 1 der komplette Chemi- und Katalysatorfilter; mit 2 die Nehrlagenchemisorptions und Katalysatormassen; mit 3 die den Chemisorptionsmassen vorgelagerte Trockenschicht, die zur Feuchtigkeitsaufnahme dient; mit 4 der reversierbare Ventilator, der vorzugsweise mehr Luft in den Chemisorptionsfilter hineindrückt, als er bei der Regenerierung zurücksaugt; mit 5 die Luftmenge, die durch den Filter zur Belüftung der Fahrzeugkabine hindurchgedrückt wird; mit 6 die vorzugsweise wesentlich kleinere Sekundärluftmenge, die aus der Fahrzeugkabine angesaugt und über eine Heizvorrichtung (8) stark aufgeheizt wird, so daß sie die Feuchtigkeit aus der Trocknungsschicht (3) über den Ventilator (4) abführt .The attached drawing shows: with 1 the complete Chemical and catalyst filters; with 2 the multi-layer chemisorption and catalyst masses; with 3 the dry layer upstream of the chemisorption masses, which is used to absorb moisture serves; with 4 the reversible fan, which preferably has more air in the chemisorption filter pushes in as it sucks back during regeneration; with 5 the amount of air that is pushed through the filter to ventilate the vehicle cabin; with 6 the preferably a much smaller amount of secondary air drawn in from the vehicle cabin and is strongly heated via a heating device (8) so that it removes the moisture discharges from the drying layer (3) via the fan (4).

Über (7) kann eine Kühlluftmenge mitangesaugt werden, so daß der Ventilator nicht zu heiß wird.A quantity of cooling air can be sucked in via (7) so that the fan doesn't get too hot.

Erfindungsgemäß wird bei (9) eine Sekundärluftklappe eingesetzt, die die Sekundärluftmenge (6) vor den eigentlichen Chemisorptions- und Katalysatormassen (2) einsaugen läßt, um sie somit ohne Luftfeuchteabgabe an die Sorptionsstrecke (2) den Heizanordnungen (8) zuzuführen, so daß die Sekundärluft (6) aufgeheizt die Trockenschicht (3) regeneriert.According to the invention, a secondary air flap is used at (9) which the amount of secondary air (6) before the actual chemisorption and catalyst masses (2) can be sucked in to it without releasing air moisture to the sorption section (2) to feed the heating arrangements (8) so that the secondary air (6) is heated Dry layer (3) regenerated.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebene und dargestellte Ausführungsform beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, die Regeneration der Trocknungsschicht in einem Chemisorptionsfilterpaket zur Belüftung von Autokabinen so vorzusehen, daß in der Regenerationsphase nicht die feuchte Luft über die Filtermassen (2) angesaugt werden muß, sondern hinter den Filtermassen (2), die zur Aufwärmung gelangende Sekundärluft (6) angesaugt wird, um über eine Heizvorrichtung (8) zur Regeneration der Trocknungsschicht (3) über die erfindungsgemäß vorgeschlagene Klappe (9) geführt zu werden.Of course, the invention is not limited to the above in detail described and illustrated embodiment is limited, but there are numerous Changes possible without deviating from the basic idea, the regeneration the drying layer in a chemisorption filter package for ventilation of car cabins To be provided so that in the regeneration phase the humid air does not pass through the filter media (2) must be sucked in, but behind the filter media (2), which is used to warm up arriving secondary air (6) is sucked in to a heating device (8) for Regeneration of the drying layer (3) via the flap proposed according to the invention (9) to be guided.

Weiterhin kann selbstverständlich den Trocknungs-und auch Filtermassen sowie der Sekundärluftzuführung eine Staubfilterschicht, z.B. Vliesfilter, vorgeschaltet werden, um die a) Chemisorptionsmassen, b) Katalysatormassen und c) Trocknungsmassen von Fremdstoffen wie Staub tunlichst zu befreien.Furthermore, of course, the drying and also filter masses and the secondary air supply is preceded by a dust filter layer, e.g. a fleece filter to the a) chemisorption masses, b) catalyst masses and c) drying masses to remove foreign matter such as dust as much as possible.
