Abstract

The invention relates to a chemisorption filter for separating off carcinogenic substances such as dioxin, furan, formaldehydes, PAHs, benzopyrene and other toxic substances. In the main application P 3628403.3, it is described that the filter masses having high capillary surface area are impregnated in layers with glycol and/or glycerol. In order to improve further the effect achieved as a result, according to the invention it is proposed that an expanded material, preferably perlite, moistened and impregnated with propylene glycol is used as sorption mass. When tobacco smoke is simultaneously present, it is further proposed to provide, after the propylene glycol, a layer which likewise comprises expanded materials which are impregnated with a medical soap solution.

Description

In der Patentanmeldung P 36 28 403.3 wird beschrieben, daß die Filtermassen mit hoher kapillarer Fläche mit Glykol und/oder Glyzerin schichtenweise getränkt werden.Patent application P 36 28 403.3 describes that the filter media with a high capillary surface Glycol and / or glycerin are soaked in layers.

Erfindungsgemäß wird vorgeschlagen, diesen Effekt zu verbessern, indem man Perlite oder einen anderen ge­ blähten Stoff vorzugsweise mit Propylenglykol tränkt.According to the invention, this effect is proposed improve by using perlite or another ge inflated material preferably soaked with propylene glycol.

Weiterhin wird vorgeschlagen, um z. B. bei Vorhandensein von cancerogenen Stoffen und gleichzeitigem Tabakrauch eine weitere Schicht, vorzugsweise ebenfalls geblähte Masse als vorzugsweise letzte Schicht, die durchströmt wird, anzufeuchten mit einer medizinischen Seifenlösung.It is also proposed to z. B. in the presence of carcinogenic substances and simultaneous tobacco smoke  another layer, preferably also blown Mass as preferably the last layer that flows through will moisten with a medicated soap solution.
