Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Vorliegende Erfindung betrifft ein Verfahren zum Abscheiden flüchtiger Stoffe aus Flüssigkeitsdämpfen durch rasches ■ Kühlen der bei der Destillation abziehenden Dämpfe. Bekanntlich sind viele Stoffe mit einem Dampfmedium, z. B. Fettsäuren mit Wasserdampf, leicht destillierbar, die ohne Anwendung eines solchen nicht unter Atmosphärendruck ohne Zersetzung flüchtig sind. Da man sich eineThe present invention relates to a method for separating volatile substances from liquid vapors through rapid ■ cooling of the vapors evolving during the distillation. As is well known are many substances with a steam medium, e.g. B. fatty acids with steam, easily distilled without the use of a such are not volatile under atmospheric pressure without decomposition. Since you get a

ίο solche Destillation als einen Vorgang vorstellen muß, bei welchem der osmotische Druck der zu destillierenden Flüssigkeit herabgesetzt wird,ίο think of such distillation as a process must, at which the osmotic pressure of the liquid to be distilled is reduced,

" befinden sich in dem gemeinsamen Dampfstrome die Moleküle, z. B. die der Fettsäure, getragen von dem Wasserdampfe, in einer physikalisch trennbaren Form. Da diese Stoffe größtenteils schlechte Wärmeleiter sind, muß die Länge des Kühlers verhältnismäßig groß sein, um eine vollständige Kühlung und Kondensation zu bewirken.. Durch Ausbildung des Kühlers zu einer zentrifugal wirkenden Scheidevorrichtung, z. B. einer Zyklone, wie man sie in gleicher Weise zum mechanischen Trennen von Gasen und Staubteilchen anwendet, wird eine rasche Berührung der im Dampfstrome schwebenden Moleküle mit einer Kühlfläche bewirkt und hierdurch der Kondensationsprozeß wesentlich verkürzt."In the common vapor stream, the molecules, e.g. those of fatty acid, are carried from the water vapor, in a physically separable form. Because these substances are mostly are poor heat conductors, the length of the cooler must be relatively large, to bring about complete cooling and condensation. By training the Cooler to a centrifugally acting cutting device, e.g. B. a cyclone how to get them is used in the same way for the mechanical separation of gases and dust particles a rapid contact of the molecules floating in the vapor stream with a cooling surface causes and thereby significantly shortens the condensation process.

Fig. ι und 5 stellen die äußere Ansicht, Fig. 2, 3, 4 Schnitte dar. Die Ausführung 2 hat einen Mantel, in dem bei ä die Kühlbzw. Wärmeflüssigkeit eintritt und bei e abläuft. Die Ausführung 4 ist analog 2, jedoch mit Luftkühlung angenommen. Bei α strömen die zu kondensierenden Dämpfe ein. Durch c fließt das Kondensat ab, während durch b die nicht niedergeschlagenen Dämpfe entweichen. Fig. Ι and 5 show the outer view, Fig. 2, 3, 4 sections. The embodiment 2 has a jacket in which at ä the Kühlbzw. Thermal liquid enters and runs off at e . Version 4 is analogous to 2, but assumed with air cooling. At α , the vapors to be condensed flow in. The condensate flows off through c, while the vapors that have not been precipitated escape through b.
