Verfahren zum Dichten feuerfester Körper.Method of sealing refractory bodies.
Die feuerfesten Steine zum Aufbau der Destillationsräume für Kohle, Zink u. dgl., ebenso wie der einräumigen Erhitzer in den Wärmerückgewinnungsanlagen sind immer durchlässig; die Porosität beträgt ungefähr io bis 2O Volumenprozente. Bei der Verkokung hat man die Beobachtung gemacht, daß nach einigen Tagen regelmäßigen Betriebes eine Selbstdichtung eintritt. DieseThe refractory stones for building the distillation rooms for coal, zinc and the like, just like the one-room heater in the heat recovery systems are always permeable; the porosity is approximately 10 to 20 percent by volume. When coking it has been observed that self-sealing occurs after a few days of regular operation. These
to Tatsache ist folgendermaßen zu erklären: Die Kohlenwasserstoffe von der Innenseite der Destillationskammer, die Kohlensäure der Heizgase von der Außenseite versuchen die durchlässige Wandung zu durchdringen.to fact can be explained as follows: The hydrocarbons from the inside the distillation chamber, try the carbonation of the heating gases from the outside to penetrate permeable wall.
Innerhalb des glühenden Steinmaterials wirken beide Körper unter Abscheidung festen Kohlenstoffs aufeinander ein. Die Reaktion glühender Kohlensäure mit Kohlenwasserstoffen zu Kohlenstoff ist ja eine bekannte Erscheinung, besonders im Kontakt mit glühenden Festkörpern, wie Stein, Koks u. dgl. Bricht man einen Stein aus einem dergestalt betriebenen Ofen auseinander, so findet man stets im Innern eine ganz schwarze Schicht ausgeschiedenen Kohlenstoffs.Within the glowing stone material, both bodies act as solid deposits Carbon. The reaction of glowing carbonic acid with hydrocarbons carbon is a well-known phenomenon, especially in contact with glowing Solid bodies, such as stone, coke and the like. If a stone is broken out of one in this way When the oven is in operation, you will always find a completely black layer inside precipitated carbon.
Bei der Zinkdestillation und bei der zweiräumigen Vorwärmung der Gase tritt eine solche Selbstdichtung nicht ein; sie kann keinen Bestand haben, da der Kohlenstoff bei Kontakt mit Luft immer wieder oxydiert wird. Ein Überziehen der Steine mit einer Glasur ist aber deshalb untunlich, weil diese im Betriebe auf die Dauer nicht standhalten würde.During the zinc distillation and the two-room preheating of the gases, a not such a self-seal; it cannot last because of carbon is repeatedly oxidized in contact with air. Covering the stones with one However, glaze is impractical because it does not last in the long term in operation would.
Die Erfindung betrifft ein Verfahren zum Dichten feuerfester Steine für die erwähnten Betriebe, das sich dadurch kennzeichnet, daß man in den Poren des Steinmaterials nicht verbrennbare Niederschläge durch zu Festkörpern verbrennende Gase sich bilden läßt. Ganz besonders, eignet sich dazu Siliziumwasserstoff, der zu Kieselsäure verbrennt; letztere bleibt während des Normalbetriebes unverändert.The invention relates to a method of sealing refractory bricks for the aforementioned Establishment that is characterized by the fact that one does not enter the pores of the stone material combustible precipitates can be formed by gases that burn to solid bodies. Silicon hydrogen, which burns to form silica, is particularly suitable for this purpose; the latter remains unchanged during normal operation.
Die Ausführung des Verfahrens für zweiräumige Winderhitzer gestaltet sich etwa so, daß eine genügende Zeitlang durch den einen Raum der erhitzten Wärmerückgewinnungsanlage das Gas und durch den anderen gleichzeitig Luft oder Sauerstoff geführt wird. Ähnlich wie bei dem Vorgang in den Verkokungskammern durchdringen die Gase die poröse Zwischenwand und gelangen in deren Innern zur Einwirkung aufeinander. Die Dichtung ist dabei einer gewissen Selbstregelung unterworfen, indem an den Stellen größter Undichtheit die größte Einwirkung und damit der stärkste Niederschlag erfolgt. Nach dieser Vornahme werden die Erhitzer in regelrechten Betrieb genommen; sollten sich mit der Zeit Undichtheiten zeigen, so wird das Verfahren wiederholt.The execution of the procedure for two-room wind heaters is roughly as follows: that a sufficient time through the one room of the heated heat recovery system the gas and air or oxygen through the other at the same time. Similar to the process in the coking chambers the gases penetrate the porous partition and arrive inside them to act on each other. The poetry is thereby a certain self-regulation subject, in that the greatest impact and thus the strongest precipitation occurs at the points of greatest leakage. After this has been done, the heaters are put into normal operation; should If leaks become evident over time, the procedure is repeated.
