Description

Die Erfindung bezieht sich auf einen Chemisorptionsfilter zur Beseitigung von Gerüchen und Bakterien nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a chemisorption filter to remove odors and bacteria after Preamble of claim 1.

Es ist bekannt, daß bettlägerige Patienten vielfach Geruchsbelästigungen für die Umwelt verursachen. Teilweise werden mit der Geruchsbelästigung auch Bakterien freigesetzt.It is known that bedridden patients are common Cause odor nuisance to the environment. Partly with the bad smell too Bacteria released.

Es wurde vielfach vorgeschlagen, Geräte zu bauen, die unmittelbar unter der Bettdecke angeschlossen werden, um die Geruchsbelästigung zu beseitigen.It has been proposed many times to build devices that connected directly under the duvet, to eliminate the smell.

Um Gerüche zu beseitigen und gleichzeitig Bakterien zu töten, werden vielfach UV-Röhren eingesetzt und sehr aufwendige teure Filteranlagen gebaut. To eliminate odors and bacteria at the same time kill, UV tubes are widely used and very complex and expensive filter systems built.  

Aus der DE 35 01 678 A1 ist es bekannt, auf dem Gebiet der Luftreinhaltung einen Filter einzusetzen, dessen Filterpaket, in Strömungsrichtung der Luft gesehen, folgende Schichtung aufweist: Vliesschicht, Natronkalkschicht, Aktivkohleschicht, Natronkalkschicht und Vliesfilterschicht.From DE 35 01 678 A1 it is known on the In the field of air pollution control, its filter pack, in the direction of air flow seen, has the following layering: fleece layer, Soda lime layer, activated carbon layer, soda lime layer and fleece filter layer.

Die EP 01 21 339 A2 hat ein Verfahren zur Entfernung wenigstens eines bestimmten Hydrides aus einem dieses enthaltenden und im wesentlichen keinen Sauerstoff ent­ haltenden Gas zum Gegenstand, wobei das Gas mit einem aus Aktivkohle bestehenden Adsorptionsmittel in Berührung gebracht wird, welches Kupferoxid und wenigstens einen Bestandteil einer Alkalimetall-Verbindung, einer der Erdalkalimetall-Verbindungen und einer der Verbindungen von Al, Ti, V, Cr, Mn, Fe, Co, Ni, Zn, Cd und Pb be­ stehenden Gruppe enthält, wobei ein bestimmter Druck sowie eine bestimmte Temperatur über eine vorgegebene Zeitspanne eingehalten sein müssen.EP 01 21 339 A2 has a method for removal at least one particular hydride from one of these containing and essentially no oxygen ent holding gas to the object, the gas with a activated carbon adsorbent in contact brought, which copper oxide and at least one Part of an alkali metal compound, one of the Alkaline earth metal compounds and one of the compounds of Al, Ti, V, Cr, Mn, Fe, Co, Ni, Zn, Cd and Pb be standing group, with a certain pressure as well as a certain temperature above a predetermined one Period of time must be observed.

Ausgehend von dem vorstehend geschilderten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, mit einfachen Maßnahmen eine hochwertige Geruchsabsorp­ tion und eine gleichfalls hochwertige bakterienverrin­ gernde Wirkung zu erzielen.Based on the status of the Technology, the invention has for its object  simple measures a high quality odor absorber tion and an equally high-quality bacteria reduction to achieve an irritating effect.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale im kennzeichnenden Teil des Patentanspruchs 1 gelöst.This object is achieved by the features solved in the characterizing part of claim 1.

Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous developments of the invention result itself from the subclaims.

Es wurde gefunden, daß die Wechselwirkung der Luft­ durchsätze durch saure und alkalische und wiederum saure und alkalische Massen oder umgekehrt eine enorm hohe Geruchsbeseitigung bewirkt bei gleich­ zeitiger Verminderung von Bakterien, die in der Luft zwangsläufig, z. B. bei einem bettlägerigen Kranken, mit angesaugt werden.It has been found that the interaction of the air throughputs through acidic and alkaline and again acidic and alkaline masses or vice versa enormously high odor elimination causes at the same time early reduction of bacteria in the air inevitably, e.g. B. in a bedridden patient, be sucked in.

Die geruchsabsorbierenden und bakterientötenden Filtermassen sind so gruppiert, daß sie abwechselnd alkalisch und sauer oder umgekehrt sind; als letzte neutralisierende Masse ist eine Aktivkohlemasse mit einem Staubfilter vorgesehen.The odor absorbing and bactericidal Filter masses are grouped so that they alternate are alkaline and acidic or vice versa; as the last one  neutralizing mass is an activated carbon mass provided with a dust filter.
