Description

Verfahren zur Zurückgewinnung und Regenerierung der in gebrauchtem Filtermaterial befindlichen anorganischen Bestandteile In den in der Industrie, insbesondere in der Getränkeindustrie, gebräuchlichen Filterapparaten werden in steigendem Maße Filterschichten oder Filtermassen verwendet, die aus organischen oder anorganischen Filtermaterialien oder aus Gemischen beider zusammengesetzt sind. Zu diesen Materialien gehören z. B. Cellulose, Asbest, Kieselgur, Bleicherde, Fullererde und ähnliche Stoffe.Process for the recovery and regeneration of the used Inorganic components contained in the filter material In the industry, in particular In the beverage industry, common filter devices are being used to an increasing extent Filter sheets or filter media used, made of organic or inorganic Filter materials or are composed of mixtures of both. About these materials belong e.g. B. cellulose, asbestos, kieselguhr, fuller's earth, fuller's earth and the like Fabrics.

Es ist bereits vorgeschlagen worden, gebrauchte Filtermaterialien obiger oder ähnlicher Zusammensetzung durch Waschen, Behandlung mit oxydierenden Stoffen, Säubern und Bleichen zu regenerieren. It has been suggested to use used filter materials above or similar composition by washing, treatment with oxidizing agents Regenerate fabrics, cleaning and bleaching.

Dabei werden aber fast ausschließlich nur die organischen Faserstoffe und geringe Anteile langfaseriger Asbestfasern regeneriert, während alle pulverförmigen hochaktiven Filterhilfsstoffe verlorengehen.However, only the organic fibers are used almost exclusively and small proportions of long-fibred asbestos fibers are regenerated, while all powdery ones highly active filter aids are lost.

Um die anorganischen Hilfsstoffe, insbesondere Asbest, aus gebrauchtem Filtermaterial zurückzugewinnen, ist ferner vorgeschlagen worden, dasselbe zu verfasern und zu vergären, sodann die organischen Stoffe auf nassem Wege zu oxydieren und auszuwaschen und anschließend die gewaschene Masse bei hohen Temperaturen zu trocknen und zu krempeln. To get the inorganic auxiliaries, especially asbestos, from used To reclaim filter material, it has also been proposed to fiberize the same and to ferment, then to oxidize the organic matter by wet means and to wash out and then to dry the washed mass at high temperatures and to roll up.

Dieses Verfahren ist umständlich und kostspielig.This procedure is cumbersome and expensive.

Nach vorliegender Erfindung erfolgt die Zurückgewinnung und Regenerierung der anorganischen Be- standteile des gebrauchten Filtermaterials, indem dasselbe einem Glühprozeß unterworfen wird, durch welchen alle organischen Bestandteile restlos vernichtet und die anorganischen Bestandteile gereinigt und reaktiviert werden. Etwaige aus der Verbrennung der organischen Bestandteile herrührenden Rückstände werden vorzugsweise durch Auswaschen entfernt. According to the present invention, recovery and regeneration take place of inorganic loading components of the used filter material, by subjecting it to an annealing process by which all organic Components completely destroyed and the inorganic components cleaned and be reactivated. Any resulting from the combustion of the organic components Residues are preferably removed by washing out.
