Description

Brehrohrofen zur gleichzeitigen Gewinnung von Urteer, Halbkoks und eines hochwertigen Gases. Gegenstand der Erfindung ist eine weitere Ausbildung des zur Ausführung des Verfahrens nach dem Hauptpatent benutzten Drehrohrofens.Rotary kiln for the simultaneous extraction of tar, semi-coke and of a high quality gas. The invention is a further embodiment of the Rotary kiln used to carry out the process according to the main patent.

Bei Entgasung von bitumenhaltigen Rohstoffen im Drehrohrofen hat sich gezeigt, daB, wenn die Feuerführung nicht peinlichst genau beobachtet wird, die Drehrohrwandung überhitzt wird. Um ein Zersetzen von wertvollen Bestandteilen der Teernebel und des nicht verdichtbaren Gases zu vermeiden, wurden die verschiedensten Mittel angewandt, die im wesentlichen auf eine Absaugung der Dämpfe und Gase an bestimmten gefährdeten Stellen des Drehrohrofens hinauslaufen.When degassing bituminous raw materials in the rotary kiln has shown that if the fire control is not meticulously observed, the Rotary tube wall is overheated. To a decomposition of valuable components of the To avoid tar mist and the non-compressible gas became the most varied Means applied, which essentially aimed at a suction of the vapors and gases certain endangered parts of the rotary kiln.

Die Praxis hat gezeigt, daß diese Verfahren nur zum Teil den Anforderungen entsprechen.Practice has shown that this process only partially meets the requirements correspond.

Nach der Erfindung soll die Überhitzung der Schwelgase dadurch vermieden werden, daß man in dem Drehrohrofen eine Schutzwand zwischen der heißen Ofenwand und den Nebeln anbringt.According to the invention, the overheating of the carbonization gases is to be avoided be that in the rotary kiln a protective wall between the hot furnace wall and apply the mists.

Diese Schutzwand kann mit einer Isolierschicht versehen oder zum Zwecke der Kühlung doppelwandig ausgebildet sein.This protective wall can be provided with an insulating layer or for purposes the cooling be double-walled.

Eine beispielsweise Ausführungsform ist in der Zeichnung im Längs- und Querschnitt veranschaulicht.An example embodiment is shown in the drawing in the longitudinal and cross-section illustrated.

In der oberen Hälfte des Ofens a ist ein doppelwandiger Schutzmantel b unbeweglich angebracht. Dieser Mantel wird durch Gase oder Dämpfe derart gekühlt, daß das Kühlmittel bei c eintritt und bei d den Mantel wieder verläBt. Die Gase und Dämpfe, die aus dem Schwelgut entweichen, werden, sofern sie nach oben streben, durch die gekühlte Wand vor pyrogenen Zersetzungen geschüt-t und können unzersetzt in bekannter Weise am Ende der Trommel abgesaugt werden.In the upper half of the furnace a is a double-walled protective jacket b attached immovably. This jacket is cooled by gases or vapors in such a way that that the coolant enters at c and leaves the jacket again at d. The gases and vapors that escape from the smoldering property, if they reach upwards, protected from pyrogenic decomposition by the cooled wall and can be undecomposed be sucked off in a known manner at the end of the drum.

Bei geringerer Empfindlichkeit der Schwelgase gegenüber höheren Temperaturen isoliert man nur die Schutzwand oder verwendet sie ohne Isolierung.With lower sensitivity of the carbonization gases to higher temperatures only insulate the protective wall or use it without insulation.

Ausführungsform des Drehrohrofens zur gleichzeitigen Gewinnung von Urteer, Halbkoks und eines hochwertigen Gases nach Patent 4o8111, dadurch gekennzeichnet, daß in möglichst geringem Abstand von der vom Schwelgut jeweils nicht bedeckten Fläche des Drehrohrofens ein an der Drehung des Ofens nicht teilnehmender Schirm befestigt ist, der das Vordringen der Dämpfe und Gase an die heiße Ofenwandung und damit deren Zersetzung verhütet. z. Drehrohrofen nach Anspruch i, dadurch gekennzeichnet, daß der Schutzschirm mit einer Isolierschicht versehen ist. 3. Drehrohrofen nach Anspruch i, dadurch gekennzeichnet, daß der Schutzschirm zum Zwecke der Kühlung doppelwandig ausgebildet ist. PATENT CLAIMS: i. Embodiment of the rotary kiln for the simultaneous extraction of ur tar, semi-coke and a high-quality gas according to patent 4o8111, characterized in that a screen which does not participate in the rotation of the kiln is attached at the smallest possible distance from the surface of the rotary kiln which is not covered by the smoldering material Penetration of the vapors and gases on the hot furnace wall and thus their decomposition prevented. z. Rotary kiln according to claim i, characterized in that the protective screen is provided with an insulating layer. 3. Rotary kiln according to claim i, characterized in that the protective screen is double-walled for the purpose of cooling.
