Abstract

A filter is made from a material which is electrically conducting so that it can be used as a resistance heater. This enables the material to be heated without separate heating devices by connecting the filter to an electrical supply. This enables the filter itself to be heated to prevent the temperature falling below the dew-point or to be used as a heating surface for catalysts.

Description

Beschreibung und ErtSuterung zur PatentanmeldungDescription and explanation of the patent application

'Aufheizbarer Filterkörper zur Gasreinigung' Es ist bekannt, schadstoffbeladene Gase durch Tuchfilter zu reinigen.'Heatable filter body for gas cleaning' It is known that pollutant-laden Purify gases through cloth filters.

Weiterhin ist bekannt, Katalysatormassen z.B. durch Ummantelung von Filterstoffen vor Fremdkörpern zu schützen, Vielfach ist es auch notwendig, Katalysatormassen aufzuheizen oder warm zu halten. Dieses wird durch Heizstäbe oder Heizgitter durchgefUhrt.It is also known to use catalyst masses, for example, by coating To protect filter materials from foreign bodies, it is often necessary to use catalyst masses heat up or keep warm. This is carried out by heating rods or heating grids.

Um ohne Fremdeinwirkung von Heizvorrichtungen das Filtermaterial selber entsprechend aufwärmen zu können, wird erfindungsgemäß vorgeschlagen, einen Filterkörper zu verwenden, der als Basis einen Filterstoff hat, der als Widerstandsheizkörper und gleichzeitig als Staubfilter Anwendung finden kann, erfindungsgemäß in der Form, daß der Filterstoff elektrisch leitfhig gemacht wird und somit a) sich selbst vor Taupunktsunterschreitungen schUtzen kann und b) auch als Aufheizfläche für Katalysatormassen Anwendung finden kann.In order to use the filter material itself without external interference from heating devices To be able to warm up accordingly, it is proposed according to the invention to have a filter body to use, which has a filter material as a base, which acts as a resistance heater and at the same time can be used as a dust filter, according to the invention in the form that the filter material is made electrically conductive and thus a) before itself Can protect below dew point and b) also as a heating surface for catalyst masses Can apply.

In der beiliegenden Zeichnung ist ein Filter entsprechend der erfindungsgemäßen Beschreibung dargestellt.In the accompanying drawing is a filter according to the invention Description shown.

In der beiliegenden Zeichnung ist dargestellt: mit 1 ein Filtergehäuse mit 2 ein filternder Körper mit 3 die elektrische Anschlußquelle mit 4 z.B. eine Katalysatorm#sse mit 5 Rohgaseintritt mit 6 Reingasaustritt.The accompanying drawing shows: 1, a filter housing with 2 a filtering body with 3 the electrical connection source with 4 e.g. Catalyst mass with 5 raw gas inlet with 6 pure gas outlet.
