Description

Destillierkolonne mit Einrichtung zur Verhinderung des Siedeverzuges. Bei den bekannten Destillierkolonnen findet durch Siedeverzug vielfach ein Erwärmen der Flüssigkeiten über ihre Siedetemperatur statt, so daß C berhitzungen derselben erfoigen, ein -'bdestillieren der Dämpfe dagegen nicht oder nur ste3weise und ungleichmäßig eintrit..Distillation column with device to prevent delayed boiling. In the known distillation columns, there is often a warming due to delayed boiling the liquids take place above their boiling point, so that C overheating of the same In contrast, the vapors are not distilled in, or only in stages and unevenly enter ..

Diese Nachteil.! v.-erden bei der Vorrichtung gemäß der vorliegenden Erfindung vermieden; dieselbe bezweckt insbesondere eine gleichrnißige Ausnutzung aller den zu verdamptenden Flüssigkeiten zugeführten @Värmeeinlieiteii.This disadvantage.! v.-grounding in the device according to the present invention Invention avoided; the same aims in particular to be uniform Exploitation of all the liquids to be vaporized @ Värmeeinlieiteii.

Die Vorrichtung besteht aus einer Destillierkolonne, in welcher sich Stufen mit Heizr-)hren, wie sie an sich für den.- gleichen Zweck bekannt sind, reit Stufen abwechseln, die mit einer Verzögerungsfüllung, z. B. Raschigschen Ringen, gefüllt oder mit sonstigen Widerständen versehen sind. Die Verwendung von Verzügerungsfüllunnen und N%'iderständer in Destillierkolonnen ist ebenfalls nicht neu.The device consists of a distillation column in which Steps with heating tubes, as they are known for the same purpose Alternate levels that begin with a delay fill, e.g. B. Raschig rings, filled or provided with other resistances. The use of delay fills and N% 'id stand in still columns is also not new.

Nachdem die Flüssigkeit in den Heizrohren erwärmt worden ist. breitet sie sich über die Verzögerungsfüllung oder die Widerstände in großer Oberfläche: aus. Hierdurch wird der Siedeverzug aufgehoben; es tritt ein dem Siedepunkt und der herrschenden Temperatur entsprechendes Verdampfen ein.After the liquid has been heated in the heating tubes. spreads they are about the delay filling or the resistances in large surface: the end. This eliminates the delay in boiling; it enters the boiling point and evaporation corresponding to the prevailing temperature.

Die Dämpfe können entweder aus den einzelnen, mit Verzögerungsfüllungen versehenen Stufen abgeleitet werden oder aus einem in der obersten Stufe angebrachten Stutzen austreten, nachdem sie vorher die darüber belegenen Stufen durchströmt haben.The vapors can either come from the individual, with delay fillings provided steps can be derived or from one attached in the top step Exit nozzle after they have previously flowed through the steps above.

Die Erfindung ist in der Zeichnung im Attfriß beispielsweise veranschaulicht.The invention is illustrated in the drawing in the Attfriß, for example.

Die zu verdampfende Flüssigkeit tritt durch das Rohr t in die Stufe 2 ein, gelangt dann in die Rohre to der Stufe 3, an deren innerer Wandun;- sie herabrieselt, hierauf in die mit #--erzögerungsfüllung versehene Stufe .l, in die Rohre io der Stufe 5, in die mit %"er;#-ögerungs- f üllung versehene Stute h, durch die Rohre t o der Stufe 7, in die Stufe S und verläßt die Vorrichtung durch den Stutzen @j. Die verdampftest ?enteile der Flüssigkeit verlassen die @ orri: htusi-" durcb elesi Stutzen 13 oder durch Auslasse, die in den Stufen b und 8 vorgesehen sein können (nicht dar- gestellt ). Die Stufen 3, 5 und ? «erden durch die Stutzen i r und 12 vor. Dati»' durc h@trömt, der die durch die Rohre i o @iesclnde Flüssig- keit beheizt. The liquid to be evaporated passes through the pipe t enters stage 2, then enters the pipes to the stage 3, at their inner Wandun; - it trickles down, then into the with # - delay filling provided level .l into the Pipes io of level 5, into which with% "er;# - öger- Filling provided mare h, through the pipes to the level 7, in the level S and leaves the Device through the nozzle @j.
