Description

Verfahren zum Zersetzen von Schwefelwasserstoff und zum Reinigen von Schwefelwasserstoff enthaltenden Gasen Um reinen oder mit anderen Gasen vermischten Schwefelwasserstoff zu freiem Schwefel und Wasser zu oxyjieren, kann man bekanntlich die genannten Gase nach Beimischung von Luft oder Sauerstoff über aktive Kohle leiten. Der Zustand der Kohle konnte bei den bisherigen Ausführungsweisen grobkörnig bis feinpulverig sein; die Kohle konnte in bezug auf den- Gasstrom ruhig liegen oder als innerlich bewegungslose Masse parallel oder quer zum Gasstrom bewegt werden. Bei dem neuen Verfahren wird nun die Kohle als feines Pulver im Gasstrom zum Schweben gebracht und von diesem fortgetragen.Process for decomposing hydrogen sulfide and purifying Gases containing hydrogen sulfide To be pure or mixed with other gases It is well known that hydrogen sulfide can be oxidized to free sulfur and water pass the gases mentioned over active charcoal after admixture of air or oxygen. The condition of the coal could be coarse-grained in previous versions be fine powder; the coal could lie still with respect to the gas flow or be moved as an internally motionless mass parallel or transversely to the gas flow. With the new process, the coal floats as a fine powder in the gas stream brought and carried away by this.

Um die um jedes Kohleteilchen sich infolge Massenanziehung bildende Gashülle schnell zu erneuern (was bei den bisher bekannten Arbeitsweisen durch den Gasstrom selbst geschieht), bedarf es bei demneuen Verfahren mechanischer, wirbelerzeugender Mittel. Eine Vorrichtung in diesem Sinne läßt sich z. B. nach dem Vorbilde einer sogenannten Desintegratormühle bauen, wobei das Gaskohlepulvergemisch im Mittelpunkt eingeführt, darauf durch die Eisenstabkränze der beiden gegeneinanderlaufenden Körbe energisch durcheinandergewirbelt und schließlich gegen die Peripheriewand geschleudert wird, an deren tiefster Stelle das Gaskohlepulvergemisch wieder austritt. Während des Laues durch diese Vorrichtung wandert der Schwefel aus dem Gas in die Kohle. Der Oxydationsvorgang wird durch den Umstand beschleunigt, daß infolge der Reibung der Eisenstäbe gegen das Gas und des Gases gegen die schwebenden Kohleteilchen nicht nur Wärme erzeugt wird, sondern auch elektrische Erregungzustände hervorgerufen werden, welche sich in der Ionisierung eines Teils der Elementargase und einer entgegeng.-#setr_t elektrischen Ladung der schwebenden Kohle äußern.About the mass attraction that forms around every particle of coal Replace the gas envelope quickly (which was the case with the previously known working methods by the Gas flow itself happens), the new process requires mechanical, vortex-generating Middle. A device in this sense can be, for. B. along the lines of a Build a so-called disintegrator mill, with the gas coal powder mixture in the center introduced, then through the iron bar wreaths of the two baskets running against each other vigorously whirled around and finally thrown against the peripheral wall at the lowest point of which the gas carbon powder mixture emerges again. While The sulfur migrates from the gas into the coal as soon as it passes through this device. The oxidation process is accelerated by the fact that as a result of friction the iron rods against the gas and the gas against the floating coal particles not only heat is generated, but also electrical excitation states which result in the ionization of a part of the elementary gases and an opposite .- # setr_t express electric charge of the floating coal.

Das austretende Gemisch von Gas und Schwefelkohle durchströmt nun weiter zunächst eine Kammer oder einen Windsichter, in welchem das Gas den größten Teil der schwebenden Schwefelkohle fallen läßt, und darauf eine elektrische Gasentstaubungseinrichtung, in welcher der Rest der schwebenden Schwefelkohle in einem Gleichstromhochspannungsfelde auf der Kathode niedergeschlagen wird. Das die Entstaubungseinrichtung verlassende Gas ist schwefel- und kohlefrei.The emerging mixture of gas and carbon disulfide now flows through further first a chamber or an air classifier, in which the gas is the largest Drops part of the floating carbon disulfide, and on top of it an electric gas dedusting device, in which the rest of the floating carbon disulfide is in a high voltage DC field is deposited on the cathode. The one leaving the dust collector Gas is sulfur and carbon free.

Die in der Kammer bzw. dein Windsichter niedergefallene und die in der elektrischen Entstaubungseinrichtung niedergeschlagene Kohle werden vereinigt und durch Entschwefelung regeneriert. Der technische Fortschritt gegenüber den bekannten Verfahren besteht darin, daß die Einrichtung kleiner und der Kohleeinsatz geringer ist, weil das Kohlepulver wie eine umlaufende Flüssigkeit beständig im Fluß bleibt.The one that fell in the chamber or your wind sifter and the one in The coals precipitated by the electric dust collector are combined and regenerated by desulfurization. The technical progress compared to the known Method consists in making the facility smaller and the use of coal is lower because the carbon powder is like a circulating liquid in the The river remains.
