Description

Verfahren zur Behandlung von Asbest für Filtrierzwecke.Process for treating asbestos for filtering purposes.

Gegen unerwünschte Bestandteile des in der Natur gewonnenen Asbests für Filtrierzwecke ist man bisher in der Weise vorgegangen, daß man sie mittels Chemikalien herauslöste. Dadurch wird aber die Konsistenz und die Porengröße des Asbests beeinflußt. Against unwanted components of the asbestos obtained in nature for filtering purposes one has hitherto proceeded in such a way that they are by means of Leached out chemicals. This, however, affects the consistency and pore size of the Asbestos affects.

Das unterbleibt, wenn man der Erfindung gemäß den Asbest mit alkalischen oder sauren Gasen oder Dämpfen unter dem von der jeweiligen Dichte des Asbest erforderten Druck behandelt, so daß die im Asbest als mechanische und in chemischer Bindung vorhandenen und für die Filtration schädlichen Beimengungen für die zu filtrierende Flüssigkeit unschädlich gemacht werden und der Asbest dadurch gegen die Einwirkung der zu filtrierenden Flüssigkeit indifferent bleibt.That does not happen if one of the invention according to the asbestos with alkaline or acidic gases or vapors below that required by the specific density of the asbestos Pressure treated so that those in asbestos as a mechanical and in chemical bond existing and harmful for the filtration additions for the to be filtered Liquid are rendered harmless and the asbestos thereby against the effects the liquid to be filtered remains indifferent.

Die Wahl des Reaktionsmittels hängt von der Zusammensetzung der jeweiligen Asbest art und von der Reaktion der zu filtrier, enden Flüssigkeit ab. Je nach Art des Falles können also sowohl alkalische wie auch sauer wirkende Stoffe zur Anwendung kommen, z. B. The choice of reactant depends on the composition of the particular Type of asbestos and the reaction of the liquid to be filtered. Depending on the type If so, both alkaline and acidic substances can be used come, z. B.

Oil3, HC1, HF1, CO2, SO2.Oil3, HC1, HF1, CO2, SO2.

Dieses Verfahren beläßt dem Asbest seine ursprüngliche Porosität und seine Glätte. This process leaves the asbestos in its original porosity and its smoothness.

PATENTANSPRUCH: Verfahren zur Behandlung von Asbest für Filtrierzwecke, dadurch gekennzeichnet, daß die im Asbest als mechanische und in chemischer Bindung vorhandenen und für die Filtration schädlichen Beimenzungen für die zu fltrierende Flüssigkeit unschädlich gemacht werden, indem der Asbest mit alkalischen oder sauren Gasen oder Dämpfen, z. B. NH3, HC1, HF1, CO2, SO2, unter Druck behandelt wird. PATENT CLAIM: Process for treating asbestos for filtering purposes, characterized in that the asbestos as a mechanical and chemical bond existing and harmful for the filtration additions for the to be filtered Liquid can be rendered harmless by mixing the asbestos with alkaline or acidic Gases or vapors, e.g. B.
