Abstract

In the patent application, a chemisorption filter composition is described which serves for absorbing pollutants in occupied spaces. In thermal destruction, the filters used do not have a pollutant-releasing action but a pollutant-binding action.

Description

Es ist bekannt, insbesondere in neuerer Zeit, daß Filter zur Abscheidung von Bakterien, Viren, staubförmigen und gasförmigen Schadstoffen und sonstigen fliegenden Aller­ genen zur Wohnraumreinigung genutzt werden.It is known, especially more recently, that filters for the separation of bacteria, viruses, dusty and gaseous pollutants and other flying allergens genes can be used for cleaning the living area.

Wichtig hierbei ist, daß diese Filter so beschaffen sein müssen, daß sie einerseits für Bakterien und gasförmige Schadstoffe absorbierend wirken und andererseits bei deren Vernichtung keine Schadstoffe freisetzen.It is important that these filters are designed in this way need to be on the one hand for bacteria and gaseous Harmful substances and on the other hand their destruction does not release any pollutants.

Aus diesem Grunde wird erfindungsgemäß vorgeschlagen, Filtermaterial zu nutzen, daß bei der anschließenden Verbrennung in einer Müllverbrennungsanlage chemisor­ bierend auf die Schadstoffe, die bei der Müllverbren­ nung freigesetzt werden, einwirken.For this reason, the invention proposes To use filter material that in the subsequent Incineration in a chemisor waste incineration plant based on the pollutants involved in garbage burning release are released.

Der erfindungsgemäße Gedanke beruht darauf, daß die Filter umweltfreundlich thermisch vernichtet werden können, ohne dabei selbst Schadstoffe freizusetzen, sondern daß vielmehr gleichzeitig Schadstoffe bindend in der Verbrennungstechnik wirken. The idea of the invention is based on the fact that Filters are thermally destroyed in an environmentally friendly manner can, without releasing pollutants themselves, but rather that at the same time binding pollutants act in combustion technology.  

Erfindungsgemäß sind daher die Filtermassen zusammenge­ setzt aus Alkali- und Erdalkali-Verbindungen und zu­ sätzlich einem Anteil Eisenverbindungen, z. B. als Eisensalz, und wirken bei der Verbrennung katalytisch NO x -mindernd.According to the invention, the filter masses are therefore composed of alkali and alkaline earth compounds and in addition a proportion of iron compounds, eg. B. as iron salt, and have a catalytic NO x -reducing effect during combustion.

Claims (2)

1. Filter zur Absorption von Schadstoffen in bewohnten Räumen, dadurch gekennzeichnet, daß sie so ausgebildet sind, daß sie bei der thermischen Vernichtung nach dem Gebrauch keine Schadstoffe freisetzen, sondern in der thermischen Zersetzung schadstoffbindend wirken.1. Filter for the absorption of pollutants in inhabited rooms, characterized in that they are designed so that they do not release any pollutants during thermal destruction after use, but act in a thermal decomposition to bind pollutants. 2. Filter nach Anspruch 1, dadurch gekennzeichnet, daß die Filtermassen aus alkalischen und erdalkalischen Massen und zusätzlich aus Eisensalzverbindungen bestehen, so daß diese genannten Massen bei der thermischen Zerset­ zung saure Schadstoffe, wie SO2, HCl, HF, binden und NO x -katalytisch reduzieren.2. Filter according to claim 1, characterized in that the filter masses consist of alkaline and alkaline-earth masses and additionally of iron salt compounds, so that these masses bind thermal pollutants such as SO 2 , HCl, HF, and NO x in thermal decomposition. reduce catalytically.
