Abstract

Dust filters and chemisorption filters, preferably for motor vehicles, are to be used in such a way that they comprise acidic and/or alkaline compositions which are used with additionally added polyhydric alcohols and activated charcoal-dust mixture, additionally oversprayed with these and/or with an integrated additional layer.

Description

Es ist bekannt nach Patentanmeldungen von Hölter, saure, alkalische und neutrale Schichten in Filter zu integrieren, um Schadgase, Schad- und Geruchsstoffe zu absorbieren.It is known from patent applications by Hölter, sour, integrate alkaline and neutral layers in filters, to absorb harmful gases, pollutants and odors.

Erfindungsgemäß wird vorgeschlagen, den einzusetzenden Filtermassen, bestehend aus saugfähigen porösen Schütt­ massen und/oder Vliesschichten, die sauer und alkalisch getränkt sind und in dieser Folge eingesetzt werden, eine Filterschicht obigen Materials mit mehrwertigen Alkoholen, bevorzugt Glycerin getränkt, als Vorfilter vorzuschalten, um eine maximale Vorabscheidung von Staub, festen und gas­ förmigen HC-Verbindungen zu erreichen.According to the invention, it is proposed to be used Filter media consisting of absorbent porous bulk mass and / or fleece layers that are acidic and alkaline are soaked and used in this episode, one Filter layer of the above material with polyhydric alcohols, preferably soaked in glycerin, upstream as a prefilter, for maximum pre-separation of dust, solid and gas to achieve shaped HC connections.

Weiterhin wird erfindungsgemäß vorgeschlagen, daß bei den sauer und alkalisch getränkten Filterschichten durch Auf­ sprühen oder Zugabe zur Tränkflüssigkeit von mehrwertigen Alkoholen, bevorzugt Glycerin, eine Steigerung der Absorption von Schadgasen, Schad- und Geruchsstoffen erreicht wird, aber auch gleichzeitig bei Betrieb in den Wintermonaten ein Einfrieren oder Überfrieren ver­ hintert wird, ohne daß die Aktivität des Chemisorptions­ filters, insbesondere für Kraftfahrzeuge und/oder auch für ähnliche Aufgabenstellungen eingeschränkt wird.Furthermore, the invention proposes that the acidic and alkaline soaked filter layers by opening spray or add to the drinking liquid of polyvalent Alcohols, preferably glycerin, an increase in Absorption of harmful gases, pollutants and odors is achieved, but also at the same time when operating in freezing or freezing in the winter months is deposited without the activity of chemisorption filters, in particular for motor vehicles and / or also  is restricted for similar tasks.

Auch auf die im Filtersystem nachgeschaltete A-Kohle­ schicht kann ein mehrwertiger Alkohol, bevorzugt Glycerin, aufgesprüht werden.Also on the A-carbon downstream in the filter system Layer can be a polyhydric alcohol, preferred Glycerin to be sprayed on.
