Abstract
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.
