Abstract

The invention describes a chemisorption filter having chemisorption layers which are alternately arranged to be alkaline, acidic, neutral or the other way round, which are characterised in that the individual liquid-absorbing layers are felt layers which are impregnated with the appropriate liquids to be alkaline, acidic and/or neutral or the other way round and are dried and, packed one above the other in alternating action, are used as chemisorption filters, hydrophobic, water-repelling separating layers being positioned between the chemisorption layers and the activated charcoal layer not being used as the last chemisorption layer but the last filter stage used being an alkaline or acidic filter stage.

Description

In der Hauptanmeldung P 36 12 932.1 wird bereits be­ schrieben, daß zur Tötung von Keimen und Wegnahme von Gerüchen aus der Atemluft Chemisorptionsmassen mit unterschiedlichen pH-Werten in wiederholtem Wechsel von alkalisch zu sauer und/oder neutral oder umgekehrter Wechselwirkung genutzt werden.In the main application P 36 12 932.1 is already wrote that to kill germs and take away Odors from the breathing air with chemisorption compounds different pH values in repeated changes from alkaline to acidic and / or neutral or vice versa Interaction.

Um noch eine wesentliche Verbesserung zu erzielen, wird erfindungsgemäß vorgeschlagen, daß staubabscheidende Stoffe, insbesondere in Faserform mit den spezifischen Massen getränkt und so im Wechselspiel sauer, alkalisch oder umgekehrt, je nach Einsatz und abzutötenden Bak­ terien, Keimen, Pilzen, Viren, im Krankenhausbereich, Wohnbereich, Laborbereich oder bei Allergie-Erkrankungen eingesetzt werden. In order to achieve a significant improvement, proposed according to the invention that dust-collecting Fabrics, especially in fiber form with the specific Masses soaked and so acidic, alkaline in the interplay or vice versa, depending on the mission and the Bak to be killed terien, germs, fungi, viruses, in the hospital area, Living area, laboratory area or for allergy diseases be used.  

Die zur Anwendung kommenden, feuchtigkeitsaufnehmenden, filzartigen Matten, mit der entsprechenden alkalischen und/oder neutralen und/oder sauren Waschflüssigkeit getränkt, werden getrocknet und als mattenförmiges Abscheidematerial in Chemisorptionsfilter nach vorher beschriebenem System eingebaut.The moisture-absorbing, felt-like mats, with the appropriate alkaline and / or neutral and / or acid washing liquid soaked, dried and as a mat Separation material in chemisorption filter after described system installed.

Weiterhin wird erfindungsgemäß vorgeschlagen, zwischen den einzelnen alkalischen, sauren und/oder neutralen Schichten feuchtigkeitsabscheidende hydrophobe Vliese als Zwischenlagen einzubauen, wodurch erreicht wird, daß keine Feuchtigkeitsaufnahme aus dem Raum erfolgt und dadurch keine Kontakte zwischen alkalischen, sauren und neutralen bzw. zwischen neutralen, alkalischen und sauren Schichten erfolgen, und keine Neutralisations­ übergänge, insbesondere bei sauren und alkalischen Chemisorptionsschichten, entstehen können.Furthermore, the invention proposes between the individual alkaline, acidic and / or neutral Layers of moisture-wicking, hydrophobic fleeces to be installed as intermediate layers, whereby that there is no moisture absorption from the room and therefore no contact between alkaline, acidic and neutral or between neutral, alkaline and acid layers occur, and no neutralization transitions, especially in acidic and alkaline Chemisorption layers can arise.

Außerdem wurde gefunden, daß es für allergieerkrankte Menschen zweckdienlich ist, als letzte Chemisorptions­ filterstufe keine neutrale A-Kohle-Filterstufe zu ver­ wenden, sondern eine alkalisch oder je nach Allergie­ erkrankung sauer wirkende Chemisorptionsstufe zu benutzen.It has also been found that it is for allergy sufferers People is useful as the last chemisorption filter stage no neutral carbon filter stage available apply, but an alkaline or depending on the allergy  disease acidic chemisorption level to use.

Hierzu benutzt man z.B. Carbonate und/oder FeII-haltige saure Produkte.For this you use e.g. Carbonates and / or FeII-containing acidic products.

Claims (3)

1. Saure und/oder alkalische bzw. neutrale Chemisorptions­ schichten wechselweise alkalisch, sauer, neutral oder umgekehrt als Chemisorptionsfilter nach Hauptanmeldung P 36 12 932.1 dadurch gekennzeichnet, daß die einzelnen flüssigkeitsaufsaugenden Schichten Filzschichten sind, die mit den entsprechenden Flüssigkeiten alkalisch, sauer und/oder neutral oder umgekehrt getränkt und getrocknet werden und in wechselnder Wirkung aufein­ ander gepackt, als Chemisorptionsfilter Anwendung finden, wobei zwischen den Chemisorptionsschichten hydrophobe, wasserabstoßende Trennschichten gelagert sind.1. Acid and / or alkaline or neutral chemisorption layers alternately alkaline, acidic, neutral or vice versa as chemisorption filter according to main application P 36 12 932.1, characterized in that the individual liquid-absorbing layers are felt layers which are alkaline, acidic and / or with the corresponding liquids be impregnated and dried neutrally or vice versa and packed onto one another in an alternating effect as a chemisorption filter, with hydrophobic, water-repellent separating layers being stored between the chemisorption layers. 2. Chemisorptionsfilter nach Anspruch 1 dadurch gekenn­ zeichnet, daß die einzelnen sauer bzw. alkalisch bzw. in Wechselwirkung neutral aufeinanderliegenden Chemi­ sorptionsmatten durch absolute, nicht getränkte hydro­ phobe, wasserabstoßende Trennschichten voneinander getrennt sind. 2. Chemisorption filter according to claim 1 characterized thereby shows that the individual is acidic or alkaline or interacting neutrally chemi sorption mats by absolute, not soaked hydro phobic, water-repellent separating layers from each other are separated.   3. Chemisorptionsfilter nach Anspruch 1 und 2 dadurch gekennzeichnet, daß die A-Kohleschicht nicht als letzte Chemisorptionsschicht Anwendung findet, sondern als letzte Filterstufe eine alkalische bzw. saure Filterstufe Anwendung findet.3. Chemisorption filter according to claim 1 and 2 characterized in that the A-carbon layer is not is used as the last chemisorption layer, but as the last filter stage an alkaline or acid filter stage is used.
