Abstract
Description
Es ist bekannt, Filter zur Luftfiltration für den Autokabinenraum herzustellen, die Staub filtern.It is known to filter air for the To create car cabin space that filter dust.
Weiterhin ist bekannt, für die Luftsäuberung Filter herzustellen, die Keimfreiheit gewähren und die bakterizid und fungizid ausgelegt sind, also als absolute Keimsperre anzusehen sind.It is also known for air purification filters to produce, ensure sterility and are bactericidal and fungicidal, i.e. as absolute germ barrier can be seen.
Es ist weiterhin bekannt, Chemisorptionsfilter als Autofilter zu verwenden, die saure Schadstoffe wie SO2, HCl, HF, HC-Verbindungen und NO x sowie CO- Belastungen aus der zugeführten Atemluft abscheiden.It is also known to use chemisorption filters as auto filters which separate acidic pollutants such as SO 2 , HCl, HF, HC compounds and NO x as well as CO pollution from the breathed air supplied.
Weiterhin ist bekannt, Filter, die frostfrei sind durch Zusatz von Glyzerin oder ähnlichen Stoffen und gleichzeitig staubfilternde Eigenschaften haben, zu verwenden. It is also known to have filters that are frost-free by adding glycerin or similar substances and at the same time have dust-filtering properties use.
Weiterhin ist bekannt, Filter, unter Beibehaltung ihrer staubfilternden Eigenschaften, durch Benetzen mit Glyzerin oder ähnlichen Stoffen frostfrei einzusetzen.It is also known to maintain its filter dust filtering properties, by wetting with Use glycerin or similar substances frost-free.
Filtereinheiten, die jeweils die einzelnen Schritte als Absolutfilter darstellen, sind im Automobil nicht unterzubringen, insbesondere im Pkw-Bereich nicht, da die notwendigen Räume nicht zur Verfügung gestellt werden können, da im Motorraumbereich und auch im Koffer raumbereich keine großzügigen Platzverhältnisse vorge sehen sind.Filter units, each of the individual steps represent as absolute filters are not in the automobile not to accommodate, especially in the car sector, because the necessary rooms are not provided can be because in the engine compartment area and also in the suitcase no generous space available are seen.
Um bei den beengten Raum- oder Platzverhältnissen trotz dem Filter zur Erzeugung atembarer Luft zu installieren, die den Anforderungen hinsichtlich Luftgüte gerecht wer den, wird erfindungsgemäß vorgeschlagen, ein dünneres keimfreies Filtermaterial zu verwenden, d. h. ein Filter material so zu tränken, daß es zwar Keime durchläßt und festhält, aber die festgehaltenen Keime sich nicht ver mehren können. Erfindungsgemäß wird dadurch erreicht, daß relativ dünne, platzsparende Filterschichten mit geringem Delta P Anwendung finden können. In order to install in the confined space or space despite the filter for generating breathable air that meet the requirements regarding air quality, the invention proposes to use a thinner aseptic filter material, ie to soak a filter material so that it does have germs lets through and holds, but the captured germs cannot multiply. According to the invention it is achieved that relatively thin, space-saving filter layers with a low Delta P can be used.
Es wird daher erfindungsgemäß vorgeschlagen, mit dem Filtermaterial doppelwirksame Tränkungen durchzuführen, die dann als Filter zusammengesetzt die Keimfreiheit, Schadstofffreiheit, Geruchsfreiheit der Luft, auch bei Frost im Winter, garantieren.It is therefore proposed according to the invention with the To carry out filter material double-acting impregnations, which then put together as a filter the sterility, Freedom from pollutants, odorlessness of the air, also with Frost in winter, guarantee.
Dieses wird erreicht, indem man Filtermaterialien mit alkalischen, sauren und zusätzlich einer nicht toxischen geruchsneutralen oxidativen Flüssigkeit mit zeitlicher Wirkung tränkt, im Filter nacheinander schichtet und wirksam werden läßt, wobei die alkalische, saure und oxidative Behandlung der Luft geruchsneutralisierend wirkt. Um die Frostfreiheit zu erzielen, wird erfindungs gemäß weiter vorgeschlagen, daß diese Tränkungen gleich zeitig mit einem frostbefreienden (chemisch, physikalisch, physiologisch) und geruchsneutralem Lösungsmittel ver sehen wird, so daß auch bei überfrierendem Nebel der Filter noch aktiv bleibt.This is achieved by using filter materials with alkaline, acidic and additionally a non-toxic odorless oxidative liquid with time Effect soaks, layered in the filter and can be effective, the alkaline, acidic and oxidative treatment of the air odor neutralizing works. In order to achieve freedom from frost, fiction further suggested according to that these impregnations are equal early with a frost-releasing (chemical, physical, physiologically) and odorless solvent ver will see, so that even with freezing fog Filter still remains active.
Selbstverständlich ist die Erfindung nicht auf vorstehend im einzelnen beschriebene Ausbildungsform beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne von dem Grundgedanken abzuweichen, Luft filter mit keimfreien, schadstofffreien, geruchsneu tralisierenden und frostfreien Eigenschaften zu ver wenden, indem wenig platzbeanspruchende Filtermassen mehrfach unterschiedlich getränkt, vorzugsweise in mehrlagiger Ausführung, das Gesamtfiltersystem darstellen.Of course, the invention is not based on Form of training described above in detail limited, but there are numerous changes possible, without deviating from the basic idea, air Filters with aseptic, pollutant-free, new smell trales and frost-free properties turn by using little filter masses soaked several times, preferably in multilayer design, the overall filter system represent.
