Description

Verfahren zur Herstellung eines zum Entfernen von festen Bestandteilen aus Gasen und Dämpfen, insbesondere Gichtgasen, bestimmten Filters.Process for the preparation of a solid component removal system from gases and vapors, especially furnace gases, certain filters.

Durch das vorliegende Verfahren soll einem empfindlichen Nachteile, welcher sich bisher bei der Trockenfiltration von Gasen, -insbesondere Hochofengasen, gezeigt hat, begegnet werden. Filter für den vorliegenden Zweck werden bisher in der Weise hergestellt, daß Asbest oder Schlackenwolle auf oder zwischen Versteifungsmitteln, wie Drahtgeweben, gelochten Blechen o. dgl., befestigt werden, um auch die feinsten Staubteile aufzufangen. Hierbei zeigt sich der Nachteil, daß die auf oder zwischen den Geweben gelagerte Mineralfaserschicht durch die Saug-und Druchwirkungen, welchen die Filter ausgesetzt sind, in kurzer Zeit beschädigt und durohlöchert wird, denn die Versteifungsmittel dürfen nicht feinmaschig gehalten sein, da sich sonst der Staub im Vlies zwischen den Versteifungsniitteln festsetzt, so daß in kurzer Zeit jede Filtration unmöglich ist. The present method is intended to cause a sensitive disadvantage, which has so far been used in the dry filtration of gases, especially blast furnace gases, has shown to be met. Filters for the present purpose are so far in manufactured in such a way that asbestos or slag wool on or between stiffeners, such as wire mesh, perforated sheet metal or the like, can be attached to even the finest Catch dust particles. This shows the disadvantage that the on or between The mineral fiber layer stored in the fabrics through the suction and pressure effects, which the filters are exposed, damaged and seared in a short time, because the stiffening agents must not be fine-meshed, otherwise the Dust sticks in the fleece between the stiffening means, so that in a short time any filtration is impossible.

Die Rückseite des Filters, in welchem sich der Staub fängt, muß daher mit einem weitmaschigen Versteifungsmiftel versehen sein, was zur Folge hat, daß der Gasstrom, welcher zur Abblasung des am Filter haftenden Staubes zurückgeblasen wird, das Mineralfaservlies in kurzer Zeit beschädigt oder durchjöchert.The back of the filter, in which the dust is caught, must therefore be provided with a wide-meshed stiffening means, which has the consequence that the gas flow which is blown back to blow off the dust adhering to the filter the mineral fiber fleece is damaged or perforated in a short time.

Diese Nachteile werden gemäß vorliegender Erfindung dadurch behoben, daß man das aus Mineralfasern bestehende, im Watteherstellungsverfahren erzeugte Vlies vor seiner Verwendung, d. h. vor seiner Verbindung mit den Versteifungsmitteln für sich allein mit Wasserglas behandelt (imprägniert), um erst nach erfolgter Trocknung mit den Versteifungsmitteln verbunden zu werden. Durch die Behandlung mit Wasserglas wird das Vlies verfilzt und bildet so ein nicht gewebtes, tuchartiges Gebilde. Das Befestigen dieses Vlieses auf den Versteifungsmitteln kann ebenfalls mit Wasserglas erfolgen. According to the present invention, these disadvantages are eliminated by that one made of mineral fibers in the cotton wool manufacturing process Fleece before use, d. H. prior to its connection with the stiffeners Treated (impregnated) with water glass on its own, only after drying to be connected to the stiffening means. By treating with water glass the fleece is felted and thus forms a non-woven, cloth-like structure. That Attaching this fleece to the stiffeners can also be done with water glass take place.
