Description
Die Erfindung bezieht sich auf einen elektrischen Widerstandsofen insbesondere zur Erhitzung gasförmiger Medien mit in einem Strömungskanal angebrachten Heizelementen aus elektrisch-isolierenden Hohlkörpern, in denen die unmittelbar vom Medium umströmten Heizleiter angeordnet sind. Ein solcher Widerstandsofen ist aus der US-PS 32 70 182 bekannt. Dabei sind die elektrisch-isolierenden Hohlkörper in einem einheitlichen, größeren Isolierblock zusammengefaßt. Bei etwaigen Schäden an dem Isolierblock müssen deshalb der gesamte Block und auch die Heizleiter ausgewechselt werden.The invention relates to an electric resistance furnace, in particular for heating gaseous Media with heating elements made of electrically insulating hollow bodies installed in a flow channel, in which the heating conductors around which the medium flows are arranged. Such a resistance furnace is known from US-PS 32 70 182. The electrically insulating hollow bodies are in one uniform, larger insulating block combined. In the event of any damage to the insulating block, you must the entire block and also the heating conductors can be replaced.
Der Erfindung liegt daher die Aufgabe zugrunde, einen elektrischen Widerstandsofen zu schaffen, der einfach aufgebaut ist und auch zu Reparaturzwecken leicht demontiert werden kann.The invention is therefore based on the object of creating an electrical resistance furnace which is simply constructed and can also be easily dismantled for repair purposes.
Diese Aufgabe wird dadurch gelöst, daß die elektrisch-isolierenden Hohlkörper als bündelartig zusammengefaßte Rohre ausgebildet sind und ferner das die Rohre umschließende Ofengehäuse doppelwandig ausgeführt ist und der dadurch gebildete Hohlraum von dem gasförmigen Medium vor dem Aufheizen durchströmt wird. Durch die letztgenannte Anordnung wird ferner noch eine gute Wärmeisolierung zwischen dem Heizsystem und der Außenwand des Ofengehäuses erreicht. This object is achieved in that the electrically insulating Hollow bodies are designed as bundled tubes and also the Tubes enclosing furnace housing is double-walled and the cavity formed by it the gaseous medium flows through it before heating. The latter arrangement will furthermore, a good thermal insulation between the heating system and the outer wall of the furnace housing is achieved.
Nach einer vorteilhaften Ausgestaltung der Erfindung ist das Rohrbündel an einem Gehäusedeckel befestigt und somit in das Ofengehäuse einschiebbar. Die elektrischen Anschlüsse für die Heizdrähte können durch den Deckel nach außen geführt sein, so daß die gesamte Heizanordnung bequem auswechselbar ist.According to an advantageous embodiment of the invention, the tube bundle is attached to a housing cover and can thus be pushed into the furnace housing. The electrical connections for the heating wires can be passed through the cover to the outside, so that the entire heating arrangement can be easily replaced.
In der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt. Es zeigtExemplary embodiments of the invention are shown in the drawing. It shows
F i g. 1 die zu einem Bündel zusammengefaßten Heizelemente gemäß der Erfindung,
F i g. 2 eine schematische Darstellung einer Ausführungsform des Widerstandsofens,F i g. 1 the heating elements according to the invention combined into a bundle,
F i g. 2 a schematic representation of an embodiment of the resistance furnace,
F i g. 3 eine schematische Darstellung einer weiteren Ausführungsform des Widerstandsofens.F i g. 3 shows a schematic representation of a further embodiment of the resistance furnace.
Die Heizelemente bestehen aus keramischen Rohren 1, in die zu Spiralen gewickelte Heizleiter eingeschoben sind, und die an der Innenwand der keramischen Rohre 1 anliegen. Die Rohre 1 sind mit einer Schelle 3 zu einem Bündel zusammengefaßt, das insgesamt eine Heizanordnung 4 bildet. Diese Heizanordnung 4 wird, wie in F i g. 2 dargestellt, in einem zylindrischen Ofengehäuse 5 angeordnet, an dessen beiden Stirnseiten Rohrstutzen 6 und 7 sowie Flansche 8 und 9 zur Befestigung von (nicht dargestellten) Leitungen für das aufzuwärmende bzw. erwärmte gasförmige Medium angebracht sind. Das aufzuwärmende Medium durchströmt den Widerstandsofen 10 in Richtung der dargestellten Pfeile, wird dabei durch den Hohlraum der Rohre 1 geleitet und damit durch Vorbeiströmen an den Heizleitern aufgewärmt.The heating elements consist of ceramic tubes 1, inserted into the heating conductor wound into spirals and which bear against the inner wall of the ceramic tubes 1. The pipes 1 are closed with a clamp 3 summarized in a bundle which forms a heating arrangement 4 as a whole. This heating arrangement 4 is as in Fig. 2 shown, arranged in a cylindrical furnace housing 5, on both end faces Pipe sockets 6 and 7 and flanges 8 and 9 for fastening (not shown) lines for the to be heated or heated gaseous medium are attached. The medium to be heated flows through the resistance furnace 10 in the direction of the arrows shown, is thereby through the cavity of the tubes 1 and thus warmed up by flowing past the heating conductors.
Bei dem in F i g. 3 dargestellten Ausführungsbeispiel des Widerstandsofens ist das die Heizanordnung 4 bildende Rohrbündel an einem Gehäusedeckel 11 befestigt. Die elektrischen Anschlüsse für die Heizdrähte 2 sind durch den Deckel 11 nach außen zu Klemmen 12 und 13 geführt. Das Ofengehäuse 14 ist doppelwandig ausgebildet, so daß ein Hohlraum 15 entsteht. Das zu erwärmende Medium strömt über einen seitlich nahe der Stirnseite des Gehäuses angeordneten Rohrstutzen 16 zunächst in den Hohlraum 15 ein, strömt durch den Hohlraum 15 bis zur anderen Stirnseite des Gehäuses, strömt in entgegengesetzter Richtung durch die Heizanordnung 4 und tritt durch einen Stutzen 17 nun erhitzt aus dem Widerstandsofen aus. Durch diese Anordnung wird eine gute Wärmeisolierung zwischen dem Heizsystem 4 und der Außenwand des Ofengehäuses 14 erreicht.In the case of the FIG. The embodiment of the resistance furnace shown in FIG. 3 is that which forms the heating arrangement 4 Tube bundle attached to a housing cover 11. The electrical connections for the heating wires 2 are led through the cover 11 to the outside to terminals 12 and 13. The furnace housing 14 is double-walled formed so that a cavity 15 is formed. The medium to be heated flows over a side near the end face of the housing arranged pipe socket 16 first into the cavity 15, flows through the Cavity 15 to the other end face of the housing, flows in the opposite direction through the heating arrangement 4 and exits the resistance furnace through a nozzle 17, heated. Through this arrangement there is good thermal insulation between the heating system 4 and the outer wall of the furnace housing 14 reached.
