Die Erfindung betrifft einen Crackreaktor gemäß Oberbegriff des Patentanspruchs 1.The invention relates to a cracking reactor according to the preamble of claim 1.

Aus der US-PS 39 84 288 ist ein Crackreaktor für die aus dem Pyrolysereaktor kommenden Schwelgase bekannt, bei welchem als eine von vielen Möglichkeiten, aber als einzige Möglichkeit der elektrischen Beheizung eine Hochfrequenz-Induktionsheizung vorgesehen istFrom US-PS 39 84 288 a crack reactor for the carbonization gases coming from the pyrolysis reactor is known, in which as one of many possibilities, but as the only possibility of electrical heating a high frequency induction heater is provided

Aus der DE-A5J 11 28 850 ist — jedoch nicht im Zusammenhang mit der Abfallpyro}"se — eine Vorrichtung zur Spaltung von gas- und dampfförmigen Kohlenwasserstoffen bekannt, bei weicher 'n mehreren senkrecht zur Strömungsrichtung verlaufenden Querschnittsebener, der Reaktcrkarnmcr mehrere widerstandsbeheizte Roste übereinander liegen. Dadurch ist zwar eine über den Strömungsquerschnitt gleichmäßige Erwärmung der zu crackenden Gase erreicht, eine langgestreckte Crackzone mit über die Länge gleichmäßiger Erwärmung ist jedoch nur durch eine Vergrößerung der Anzahl der Roste erreichbar, was einen nicht unerheblichen Aufwand darstelltFrom DE-A 5 J 11 28 850 - but not in connection with waste pyrotechnics - a device for splitting gaseous and vaporous hydrocarbons is known Although this achieves uniform heating of the gases to be cracked over the flow cross-section, an elongated cracking zone with uniform heating over the length can only be achieved by increasing the number of grids, which is a not inconsiderable effort

Aufgabe der Erfindung ist es, einen widerstandsbeheizten Crackreaktor für die Abfallpyrolyse so zu gestalten, daß über sein gesamtes Volumen hinweg eine möglichst gleichmäßige Erwärmung erreicht ist.The object of the invention is to design a resistance-heated cracking reactor for waste pyrolysis in such a way that that as uniform a heating as possible is achieved over its entire volume.

Diese Aufgabe wird erfindungsgemäß durch einen Crackreaktor gelöst, wie er in Anspruch 1 gekennzeichnet ist.According to the invention, this object is achieved by a cracking reactor as characterized in claim 1 is.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous refinements of the invention are the subject matter of the subclaims.

Eine Ausführungsform des erfindungsgemäßen Crackreaktors wird im folgenden in Verbindung mit der Zeichnung beschrieben. Auf dieser zeigtAn embodiment of the cracking reactor according to the invention is described below in connection with Drawing described. On this shows

F i g. 1 den Crackreaktor im Längsschnitt undF i g. 1 the crack reactor in longitudinal section and

F i g. 2 diesen im Querschnitt mit Schnitt längs Ebene A-B. F i g. 2 this in cross section with section along plane AB.

Der Crackreaktor ist im wesentlichen zylindrisch ausgebildet und weiset als Mantel ein Rohr 1 mit Keramiküberzug auf. Im Inneren des Rohres sind über seinen Querschnitt verteilt durch elektrische Widerstände von innen beheizte Keramikstäbe 2 vorgesehen, die sich in Richtung der Achse des Rohres erstrecken. Wie in Fi g. 2 zu sehen, sind die Stäbe 2 gleichmäßig über den Querschnitt des Rohres 1 verteilt. Das Schwelgas bzw. der Schweldampf tritt über einen Einlaß 3 stirnseitig inThe cracking reactor is essentially cylindrical and has a tube 1 with a ceramic coating as a jacket on. Inside the tube are distributed over its cross section by electrical resistances of internally heated ceramic rods 2 are provided which extend in the direction of the axis of the tube. As in Fi g. 2, the rods 2 are evenly distributed over the cross section of the tube 1. The carbonization gas or the smoldering steam enters via an inlet 3 on the front side
