Description
Herstellung von Schwefelkohlenstoff Wird Schwefelkohlenstoff in Retorten, die von außen durch direkte Feuerung beheizt werden, hergestellt, so ist der Retortenverschleiß durch ungleichmäßige Erwärmung und durch Zundern sehr hoch. Um diesen Mißstand zu umgehen, hat man die Schwefelkohlenstofföfen elektrisch von innen erhitzt, wobei man gewöhnliche Schachtöfen oder nach einem Vorschlag auch retortenähnliche Gefäße benutzt hat. Bei der Innenbeheizung sind die Heizwiderstände im allgemeinen nur schwer zugängig, was Reparaturen erschwert. Auch schwankt der Stromverbrauch infolge Verkrustung der Elektroden und treten leicht lokale Überhitzungen im Innern der verhältnismäßig großen öfen ein, was Bildung von Hohlräumen und Explosionen im Gefolge haben kann.Manufacture of carbon disulfide Is carbon disulfide in retorts, that are heated from the outside by direct firing, so is the retort wear very high due to uneven heating and scaling. To this grievance too bypass, the carbon disulfide stoves have been heated electrically from the inside, whereby normal shaft furnaces or, according to a suggestion, retort-like vessels used. In the case of internal heating, the heating resistors are generally only difficult to access, which makes repairs difficult. Power consumption also fluctuates as a result Encrustation of the electrodes and local overheating easily occur inside the relatively large ovens, causing cavities and explosions as a result may have.
Diese Nachteile werden nach vorliegender Erfindung dadurch umgangen, daß die Herstellung des Schwefelkohlenstoffs in den üblichen, leicht zu handhabenden eisernen Retorten vorgenommen wird, diese aber von außen durch Strahlungsheizkörper elektrisch beheizt werden. Die Heizkörper werden in geringem Abstande von der Retortenwand angebracht und sind nach der anderen Seite hin durch Isolierschichten, z. B. Schamottemauerwerk, gegen Wärmeverluste geschützt.According to the present invention, these disadvantages are avoided by that the production of carbon disulfide in the usual, easy to handle iron retorts are made, but this is done from the outside by means of radiant heaters be electrically heated. The radiators are at a short distance from the retort wall attached and are on the other side by insulating layers, z. B. Fireclay masonry, protected against heat loss.
Bei dieser Anordnung kann man verhältnismäßig kleine Retorteneinheiten beibehalten, die infolge der gleichmäßigen Erhitzung und des Fehlens eines Angriffs durch Feuergase viel besser geschont werden als bei direkter Feuerung. Die Bedienung ist einfach und gefahrlos, und Reparaturen an den StrahlungsheizIzZ5rpern sind leicht auszuführen.With this arrangement, one can use relatively small retort units retained that as a result of uniform heating and the absence of attack are much better protected by fire gases than with direct firing. The operation is simple and safe, and repairs to the radiant heater bodies are easy to execute.
