Description
Wie bekannt, ist der Wirkungsgrad von Absorptions- und Reaktionstürmen, zu denen z. B. die Kolonnenaufsätze auf Destillierapparaten gehören, abhängig von der Häufigkeit des Zusammentreffens eines aufsteigenden Gasstromes und eines abwärts fließenden Flüssigkeitsstromes. Zur Erhöhung des Wirkungsgrades derartiger Apparaturen hat man vorgeschlagen, Füllmaterial der verschiedensten Formen aus Ton, Glas oder Metall zu verwenden. Bei anderen reaktionskinetischen Vorgängen, z. B. bei der katalytischen Hydrierung, verwendet man zur Beschleunigung der Reaktionen Palladium oder Nickel in feinverteilter Form. As is known, the efficiency of absorption and reaction towers, to which z. B. include the column heads on stills, depending on the frequency of the meeting of an ascending gas stream and a descending stream flowing liquid stream. To increase the efficiency of such equipment it has been proposed to use filling material of various shapes made of clay, glass or Use metal. In other reaction kinetic processes, e.g. B. in the catalytic Hydrogenation, palladium or nickel is used to accelerate the reactions in finely divided form.
Es wurde nun gefunden, daß zur Beschleunigung der Reaktionen chemischer Umsetzungen und/oder zur Erhöhung ihres Wirkungsgrades Geräte aus Glas, Quarz oder Keramik verwendet werden können, dierfin4ungsgemäß auf ihrer Innenfläche ganz "edy.tQiimreise mit aufgesintertem oder aufgeschmoltent Alas-} Quarz- oder Keramikpulver versehen sinkt Es ist zwar schon eine aus zusammengesintertem Glaspulver bestehende und in ein Glasteil eingeschmolzene Filterplatte bekannt. Diese bekannte Filterplatte besteht aber über ihre ganze Fläche aus kompaktem Material und ist auch ausschließlich dazu bestimmt, in Rohrleitungen als Filter eingeschaltet zu werden, so daß die vorliegenden Aufgaben damit nicht gelöst werden können. Weiterhin ist ein Verfahren zum Herstellen von körperhaften Verzierungen auf Glas bekannt, bei dem -Glaspulver eingebrannt wird. Bei diesem Verfahren wird jedoch das Glaspulver unter Anwendung eines Bindemittels aufgebracht. It has now been found that to accelerate the chemical reactions Implementations and / or to increase their efficiency devices made of glass, quartz or Ceramics can be used, which according to the invention completely travel on their inner surface provided with sintered or melted Alas-} quartz or ceramic powder It sinks, although it is already made of sintered glass powder and in a glass part fused filter plate known. This known filter plate is made but over its entire surface made of compact material and is also exclusively for this purpose intended to be switched on in pipelines as a filter, so that the present Tasks cannot be solved with it. Furthermore, there is a method of manufacturing known from bodily decorations on glass, in which glass powder is burned in will. In this method, however, the glass powder is made using a binder upset.
Das erfindungsgemäße Gerät eignet sich außer zur Durchführung chemischer Arbeiten mit spezifischen Oberflächenreaktionen z. B. auch als Flüssigkeitsbremse, um turbulente Strömungen in Rohren herzustellen. Bisher wurden hierzu Geräte mit umständlicher apparativer Ausgestaltung verwendet. The device according to the invention is also suitable for performing chemical Working with specific surface reactions e.g. B. also as a liquid brake, to create turbulent flows in pipes. So far this has been done with devices cumbersome apparatus design used.
Beispielsweise Ausführungsformen der Erfindung sind in den Abb. I und 2 dargestellt. Nach Abb. I ist die Innenseite eines Glas- oder Quarz rohres I mit einer Pulverschicht 2 aus Glas oder Quarz bedeckt, und nach Abb. 2 ist bei zwei ineinandergeführten Rohren sowohl die Innenseite des Außenrohres I als auch die Außenseite des Innenrohres 3 mit Glas- oder Quarzpulver 2 bzw. 4 versehen. Exemplary embodiments of the invention are shown in Figs and 2 shown. According to Fig. I is the inside of a glass or quartz tube I covered with a layer of powder 2 made of glass or quartz, and according to Fig. 2 is at two nested tubes both the inside of the outer tube I and the outside of the inner tube 3 is provided with glass or quartz powder 2 or 4.
Das aufgesinterte oder aufgeschmolzene Glas-, Quarz- oder Keramikpulver kann aus zwei oder mehreren Schichten mit beliebig groben Körnungen bestehen. Diese Schichten verschieden grober Körnungen können über- oder hintereinander liegen. Hintereinander angeordnete Schichten verschiedener Körnungen wird man z. B. dann mit Vorteil verwenden, wenn bei der Wirkung eines nach der Erfindung ausgestalteten Rohres als Flüssigkeitsbremse die Strömungsgeschwindigkeit in verschiedenen Teilen der Apparatur verschieden groß sein soll. The sintered or melted glass, quartz or ceramic powder can consist of two or more layers with any coarse grain size. These Layers of different coarse grain sizes can lie one above the other or one behind the other. Layers of different grain sizes arranged one behind the other are z. B. then Use with advantage when designed according to the invention at the effect Pipe as a fluid brake, the flow velocity in different parts the apparatus should be of different sizes.
