Description

Vakuum-Destillationsanlage, Es ist bei der Destillation von Ölen bekannt, das erforderliche Vakuum in der Destillationsblase, dem Dephlcgmator und dem Kühler dadurch zu erzeugen, daß man diese Vorrichtungen an einen Einspritzkondensator mit barometrischem Hrhenrohr anschließt und die Luft und die entstandenen permanenten Gase daraus mittels einer Trockenluftpumpe absaugt. Diese Einrichtung weist die Nachteile auf, daß für den Einspritzkondensator ein etwa 10 m hohes Gerüst erforderlich ist, und daß die permanenten Gase nur während ihres kurzen Aufstieges im Einspritzkondensator mit dem herabrieselnden Wasser zum Zwecke des Wärmeausgleiches in Berührung kommen.Vacuum distillation plant, It is known in the distillation of oils the required vacuum in the still, the depressor and the condenser by connecting these devices to an injection condenser barometric pipe connects and the air and the resulting permanent Sucks gases out of it by means of a dry air pump. This facility has the Disadvantages that an approximately 10 m high scaffolding is required for the injection condenser is, and that the permanent gases only during their brief rise in the injection condenser come into contact with the trickling water for the purpose of heat compensation.

Es ist ferner ein Destillationsverfahren bekannt, bei dem die von der Destillation herrilhr-nden und aus einem Kondensator austretenden Gase und Dämpfe einem mittels komprimierter oder verflüssigter Gase betriebenem Strahlapparat zugeführt werden, an den eine Trockenluffpumpe angeschlossen ist. It is also known a distillation process in which the of from distillation and gases and vapors emerging from a condenser fed to a jet device operated by means of compressed or liquefied gases to which a dry air pump is connected.

Die Erzeugung komprimierter oder gar verflüssigter Gase ist umständlich und teuer; so daß infolgedessen die verhältnismäßig geringen Mengen der kondensierbaren Produkte nicht mehr lohnend gewonnen werden können.The generation of compressed or even liquefied gases is cumbersome and expensive; so that, as a result, the relatively small amounts of condensable Products can no longer be obtained profitably.

Auch der Kraftverbrauch steigt bei diesem Verfahren derart, daß die Erzeugung des höheren Vakuums wenig wirtschaftlich ist.The power consumption increases in this method so that the Generating the higher vacuum is not very economical.

Durch die Erfindung, die in der Zeichnung schematisch dargestellt ist, werden diese Nachteile yermieden. By the invention shown schematically in the drawing these disadvantages are avoided.

Die Erfindung besteht darin, daß mit dem Dephlegmator b oder dem Röhrenkühler c einer aus diesen Vorrichtungen und einer Destillationsblase a i:nd einem Kühler f bestehenden Destillationsanlage ein tiefstehender Einspritzkondensator d mit ciner daran angeschlossenen Naßluftpumpe e in Verbindung steht. The invention consists in that with the Dephlegmator b or the Tubular cooler c one of these devices and a still a i: nd a cooler f existing distillation system a low-level injection condenser d is connected to a wet air pump e connected to it.

Die in der Blase a verdampften. Öle werden in dem Dephlegrnator b niedergeschlagen und verlassen durch den Kühler f die Anlage, während die Wasserdämpfe und die Gase durch den Röhrenkühler c dem Einspritzkondensator d zugeführt werden. Die Gase werden in dem Kondensator d durch das eingespritzte Wasser und in aer nach der Naßluftpumpe führenden Leitung innig mit dem abzusaugenden Msser in Berührung gebracht, so daß eine bessere Ausnutzung der Kälte des zugeführten Kühlwassers erfolgt. The evaporated in the bubble a. Oils are in the Dephlegrnator b knocked down and left through the cooler f the system while the water vapors and the gases are fed through the tube cooler c to the injection condenser d. The gases are in the condenser d by the injected water and in aer after the pipe leading to the wet air pump is in close contact with the knife to be sucked off brought so that a better utilization of the cold of the supplied cooling water takes place.
