Description
Filter zur Entsauerstoffung von Wässern und feuchten Gasen Vorliegende Erfindung betrifft die Anwendung eines neuen Filterstoffes zur Entsauerstoffung von Flüssigkeiten und feuchten Gasen, und zwar besteht die Erfindung in der Verwendung von Parkettstahlspänen und deren Abfällen für obige Aufgabe.Filters for the de-oxygenation of water and humid gases Present The invention relates to the use of a new filter material for de-oxygenation of liquids and wet gases, namely the invention consists in the use of parquet steel chips and their waste for the above task.
An sich ist es bekannt, Flüssigkeiten, insbesondere Wasser, als auch Luft über Metallklein, wie z. 13. Drellhobel- und Bohrspäne aus Eisen sowie Blechschnitzel, zu leiten. Dieses Material ist leicht und in genügender Ziege zu beschaffen, hat aber den Nachteil der ungleichen Spanstärke und das es in der Werkstatt entweder durch Wasser bereits angerostet oder durch ül verunreinigt ist. It is known per se, liquids, especially water, as well Air over small metal, such as 13. Drill planing and drilling chips made of iron as well as sheet metal chips, to direct. This material is easy to procure and in sufficient numbers goat has but the disadvantage of the uneven chip thickness and that it is in the workshop either is already rusted by water or contaminated by oil.
Die ungleiche Spanstärke dieses Schrottes bildet Fi Iterschichten von ungleichem Strömungswiderstand, und Späne mit einer Rost- oder Fettschicht können nur schwer oder überhaupt nicht oxydieren. The uneven chip thickness of this scrap forms layers of filing uneven flow resistance and chips with a layer of rust or grease oxidize only with difficulty or not at all.
In Erkenntnis dieser Nachteile wurde in anderen Veröffentlichungen die Verwendung von zerkleinertem und aufgerauhtem Eisendraht vorgeschlagen, wie sich dies als Abfall in der Drahtglasfabrikation ergibt. Dieses Material ist aber packig und liegt zu dicht. Recognizing these drawbacks, other publications suggested the use of crushed and roughened iron wire, such as this results as waste in wired glass production. But this material is packaged and too close.
Nach der Erfindung sollen als optimale Filterfüllung Parkettstahlspäne und deren Abfälle verwendet werden. Der Verwendungszweck dieser Späne bedingt bereits eine blanke Oberfläche von mäßiger Stärke und großer Gleichmäßigkeit. Ein Stahlspan ist elastisch, läßt sich zusammendrücken und hat scharfe Kanten. Letztere lösen besonders gut die Rostung ein. In Filterschichten liegt die Masse wie ein Schwamm, die Dichte läßt sich durc'h Pressungen regeln, wodurch der Durchflußwiderstand als auch die Volumenvergrößerung durch die Oxydation berücksichtigt ist. Vor allem geht die ;2bzehrung der Füllung überall gleichmäßig vor sich, und es bilden sich keine Krater, wodurch das Wasser oder die Luft außerhalb der Füllung hindurchschlüpfen kann. Soweit durch die Ungleichheit der Späne das eine früher wie das andere wegrostet, springt das Benachbarte an dessen Stelle, so daß der Kontakt gewahrt bleibt. Zum Beispiel zeigte die bekannte Filtermasse nach 14 Tagen Betrieb eine Zunahme des Strömungswiderstandes bis zu IO m WS und ein Absinken der Desoxydation auf weniger als die Hälfte. Dagegen zeigte sich bei Filtern mit Parkettspänefüllungen bzw. deren Ab fällen, daß in der gleichen Zeit der Strömungswiderstand sich kaum erhöhte, dagegen der Wirkungsgrad zunahm. Letzteres erklärt sich durch die Oberflächenvergrößerung durch die Rostpusteln bei gleichbleibender Wasser- bzw. Luftverteilung. According to the invention, parquet steel shavings should be the optimal filter filling and their waste is used. The intended use of these chips already dictates a bare surface of moderate thickness and great evenness. A steel chip is elastic, can be compressed and has sharp edges. Solve the latter the rust is particularly good. The mass lies in filter layers like a sponge, the density can be regulated by pressing, whereby the flow resistance as also the volume increase through the Oxidation taken into account is. Above all, the consumption of the filling is uniform everywhere, and no craters are formed, causing the water or air outside of the filling can slip through. So much for the one earlier due to the inequality of the chips as the other rusts away, the neighboring jumps in its place, so that the contact is preserved. For example, the well-known filter mass showed after 14 days of operation an increase in flow resistance up to 10 m WS and a decrease in deoxidation to less than half. In contrast, it was found in the case of filters with parquet chip fillings or their from fall that at the same time the flow resistance is hardly increased, on the other hand the efficiency increased. The latter is explained by the increase in surface area through the rust pustules with constant water or air distribution.
