Abstract

The invention relates to a chemisorption composition for eliminating odours, which is characterised in that it comprises propylene glycol-treated activated charcoal, an untreated activated charcoal layer being provided immediately downstream of the intake part for the unpurified air masses which is composed of propylene glycol-treated activated charcoal, which untreated activated charcoal layer takes up the evaporation products from the preceding layer and as a result experiences a further improved activation.

Description

Es ist bekannt, Geruchsbelästigungen durch Aktivkohle zu beseitigen.It is known odor nuisance from activated carbon to eliminate.

Erfindungsgemäß wurde gefunden, daß durch die Ober­ flächenbehandlung von Aktivkohle mit Propylen-Glykol eine wesentlich bessere Geruchsabsorption erzielt werden kann.According to the invention it was found that by the Ober Surface treatment of activated carbon with propylene glycol much better odor absorption can be achieved can.

Bevorzugt erfolgt das Aufbringen dieser Propylen-Glykol­ schicht durch Aufdampfen.This propylene glycol is preferably applied layer by vapor deposition.

Ein weiterer erfindungsgemäßer Vorteil ist dadurch ge­ kennzeichnet, daß die erst angeströmte Schicht eine Propylen-Glykol-behandelte A-Kohleschicht ist und die nachgesetzte Schicht als reine Aktivkohle angeordnet ist. Another advantage of the invention is ge indicates that the layer that has been exposed to a Propylene glycol-treated A-carbon layer is and the subsequent layer arranged as pure activated carbon is.  

Dies bedeutet, daß bei einem Verdampfen des Propylen- Glykols in der Vorschicht diese in der sogenannten Aktivkohlen-Reinschicht hinten aufgenommen wird und hier erneut zur weiteren Aktivierung der A-Kohle beiträgt.This means that if the propylene Glycol in the pre-layer this in the so-called Activated carbon pure layer is taken up behind and here again for further activation of the activated carbon contributes.

1. Chemisorptionsmasse zur Beseitigung von Gerüchen, dadurch gekennzeichnet, daß sie aus Propylen-Glykol­ behandelter Aktivkohle besteht.1. chemisorption composition for eliminating odors, characterized in that it consists of propylene glycol treated activated carbon. 2. Chemisorptionsfilter nach Anspruch 1 zur Beseitigung von Gerüchen, dadurch gekennzeichnet, daß dem Anström­ teil der ungereinigten Luftmassen, der aus Propylen- Glykol-behandelter A-Kohle besteht, unmittelbar eine nicht-behandelte Aktivkohleschicht nachgesetzt wird, die die Ausdampfungsprodukte aus der Vorschicht mit übernimmt und dadurch eine weitere verbesserte Aktivierung erfährt.2. Chemisorption filter according to claim 1 for elimination of smells, characterized in that the inflow part of the unpurified air mass, which is made from propylene Glycol-treated activated carbon exists, immediately one untreated activated carbon layer is added, with the evaporation products from the precoat takes over and thereby a further improved activation experiences.
