Description

Von außen beheizter Drehtrommelentgaser mit sähraubengangförmigen Führungsrippen an der Drehtrommelwandung zum Entgasen bituminöser Brennstoffe bei niederer Temperatur. Die Erfindung betrifft eine Verbesserung der bisher für die Tieftemperaturverkokung gebräuchlichen Drehtrommeln. Es ist bekannt, daß die Kohle während der beginnenden Teerabschei@dung sich in einem teigigen Zustand befindet. Um ein Aufschäumen der Masse .in dieser Periode zu verhindern, darf nur mäßig erwärmt werden, und man erhält dann einen festen Halbkoks. Nach der Erfindung findet dieser Vorgang in einem mäßig erwärmten Innenrohr statt. Bildet man dieses Rohr konisch aus, nach dem Kohleneingang zu verjüngt, so fallen die Führungsrippen weg und das Zusammenbacken und Klinkern wird in hervorragender Weise begünstigt. Man erhält einen stückigen Halbkoks, der dann in der äußeren Trommel weiter entteert und fest wird. Die hier frei werdenden Destillationsgase treten auf kürzestem Wege .durch Spalten in das verhältnismäßig kühle Innenrohr ein .und sind dadurch vor Zersetzung durch die heißen Trommelwände geschützt. Ein weiterer Vorzug der Erfindung besteht, wie aus der Zeichnung ersichtlich, in dem Fortfall der Stopfbüchse oder der Abdichtung an dem einen Ende; ,der Ofen baut sich dadurch wesentlich stabiler. Die Skizze veranschaulicht ein Ausführungsbeispiel des Gegenstandes .der Erfindung bei Einbau eines zylindrischen Rohres.Externally heated rotary drum degasser with corridor shaped Guide ribs on the rotating drum wall for degassing bituminous fuels lower temperature. The invention relates to an improvement of the hitherto available for the Rotary drums commonly used at low temperature coking. It is known that the coal is in a doughy state during the beginning of the tar separation. In order to prevent the mass from foaming during this period, only moderately heated and you get a solid semi-coke. According to the invention, this takes place The process takes place in a moderately heated inner tube. If you make this tube conical if it tapers after the coal entrance, the guide ribs fall away and that Caking and clinker are promoted in an excellent way. You get a lumpy semi-coke, which then further de-tares and solidifies in the outer drum will. The distillation gases released here pass through the shortest route Fissures in the relatively cool inner tube. And are therefore from decomposition protected by the hot drum walls. Another advantage of the invention is as can be seen from the drawing, in the omission of the stuffing box or the seal at one end; , the stove is much more stable as a result. The sketch illustrates an embodiment of the subject .der invention when installing a cylindrical Pipe.

Die drehbare Entgasungstrommel ist in einen gemauerten Ofenkörper a eingebaut. Trommel und Innenrohr haben, wenn letzteres, wie in der Zeichnung angedeutet, zylindrisch ausgeführt, die bekannten schraubengangförmig sitzenden Führungsrippen. Die Kohle fällt aus dem Bunker i in die Schnecke :2 und wird von hier in das Innenrohr 3 befördert. Die Kegelform oder die Führungsrippen desselben fördern die Kohle nach der Rohröffnung io, und die Kohle fällt von hier in die äußere Trommel4, woselbst sie abermals von Führungsrippen erfaßt und nach dem feststehenden Ofenkopf 5 zum Halbkoksbunker befördert wird. Die in der Trommel 4 frei werdenden Destillationsgase gelangen durch die Öffningen 9 und io in das Innenrohr und werden aus diesem bei 6 abgesaugt.The rotatable degassing drum is in a brick furnace body a built in. The drum and inner tube have, if the latter, as indicated in the drawing, Cylindrical design, the well-known helically seated guide ribs. The coal falls from the bunker i into the auger: 2 and is from here into the inner tube 3 promoted. The cone shape or the guide ribs of the same promote the coal the pipe opening io, and the coal falls from here into the outer drum4, where it is they are again captured by guide ribs and after the fixed furnace head 5 to Half coke bunker is transported. The distillation gases released in the drum 4 get through the openings 9 and io into the inner tube and are out of this at 6 sucked off.
