Description

Vorrichtung zum Betrieb von Destillations- und ähnlichen Apparaten Bei Destillationsanlagen für kontinuierlichen Betrieb und ähnliche Anlagen ist es notwendig, die Förderleistung der Pumpen den wechselnden Mengen, welche zur Destillation gelangen bzw, die Apparature durchlaufen, anzupassen. Dieses geschieht allgemein durch Schwimmer, durch welche die Fördermenge der Pumpen entsprechend der jeweiligen Leistung der Apparature reguliert wird. Diese Schwimmerregulierung hat aber den großen Nachteil, daß sie nicht absolut zuverlässig ist.Device for operating distillation and similar apparatus In the case of distillation systems for continuous operation and similar systems, it is necessary to adjust the delivery rate of the pumps to the changing quantities required for distillation arrive or go through the apparatus to adapt. This happens generally by floats, through which the delivery rate of the pumps according to the respective The performance of the apparatus is regulated. But this float regulation has big disadvantage that it is not absolutely reliable.

Durch die vorliegende Erfindung kommen die Schwimmer in Fortfall ; die Pumpen werden in ihrer Fördermenge durch keinerlei Regulierung beeinflußt. Wenn nun die geförderte Menge geringer ist als die Förderleistung der Pumpen, werden außer der Flüssigkeit durch die Pumpe auch Luft, Gas oder Dämpfe gefördert. Dadurch, daß diese mit der Flüssigkeit geförderte Luft o. dgl, in geeigneter Weise wieder in die Ansaugleitung der Pumpe zurückgeführt wird, wird die Benachteiligung der Arheit des Apparates durch die an und für sich ungewollte gleichzeitige Förderung von Luft o. dgl. vermieden.The present invention eliminates the need for swimmers; the pumps are not influenced in their flow rate by any regulation. if Now the amount delivered is less than the delivery rate of the pumps In addition to the liquid, the pump also delivers air, gas or vapors. Through this, that this air or the like conveyed with the liquid again in a suitable manner is fed back into the suction line of the pump, the disadvantage of the Arheit of the apparatus through the in and for itself unwanted simultaneous promotion of air or the like. Avoided.

Zur Neran.schaulichung dient die schematische Zeichnung einer Destillationsanlage zur kontinuierlichen Destillation bei wechselnder Leistung des Apparates. Die gezeichnete Apparature dient zur Abdestillation von absorbierten Flüssigkeiten aus einem Absorptionsmittel Die wechselnden Mengen Absorptionsmittel fließen durch die Leitung a der Apparatur zu. Die Pumpe b saugt durch die Leitung c das Absorptionsmittel und fördert es weiter durch die Leitung d in die Nachwaschkolonne e. Die gieichzeitig mit angesaugte Luft durchläuft die Leitung f, den Ventilator g, die Leitung h, dann die Leitung i und wird in dem Punkte k wieder der Ansaugleitung der Pumpe b zugeführt. The schematic drawing of a distillation plant serves to illustrate Neran for continuous distillation with changing performance of the apparatus. The drawn Apparatus is used to distill off absorbed liquids from an absorbent The varying amounts of absorbent flow through line a of the apparatus to. The pump b sucks the absorbent through the line c and conveys it further through line d into the post-wash column e. The air that is sucked in at the same time runs through the line f, the fan g, the line h, then the line i and is fed back to the suction line of pump b at point k.

Das die Nachwaschkolonne e durchlaufende Absorptionsmittel wird unten aus derselben durch die Pumpe l, durch die Leitung m. den Wärmeaustauscher n und die Leitung o in die Destillationskolonne p gefördert. Die gleichzeitig mitgeförderte Luft geht durch den Kühler q, durch die Leitung r unten in die Nachwaschkolonne e und dadurch an die Ansaugstelle der Pumpe l zurück. The absorbent passing through the post-washing column e is at the bottom from the same through the pump 1, through the line m. the heat exchanger n and conveyed the line o into the distillation column p. The at the same time co-funded Air goes through the cooler q, through the line r at the bottom of the post-washing column e and thus back to the suction point of pump l.

Nach der Destillation sammelt sich das Absorptionsmittel unten in der Destillationskolonne p und wird von dort von der Pumpe s durch die Leitung t, dann durch den Wärmeaustauscher n und die Leitung u in das Rohr v gedrückt. Das geförderte luftfreie Öl läuft unten aus der Röhre v dem Hochbehälter w zu, von welchem aus das Absorptionsmittel dem Absorptionsapparate zugeführt wird. Die von der Pumpe s gleichzitig geförderte Luft wird aus dem oberen Teil des Rohres v durch die Leitung x dem unteren Teil der Destillationskolonne p und dadurch wieder der Ansaugstelle der Pumpe s zugeführt. After the distillation, the absorbent collects in the bottom the distillation column p and is from there by the pump s through the line t, then pressed through the heat exchanger n and the line u into the tube v. That pumped air-free oil runs down from the tube v to the elevated tank w, from which from the absorbent is fed to the absorption apparatus. The one from the pump s air conveyed at the same time is from the upper part of the tube v through the line x the lower part of the distillation column p and thus again the suction point the pump s supplied.
