Patentiert im Deutschen Reiche vom 10. Juni 1906 ab.Patented in the German Empire on June 10, 1906.

Die Erfindung betrifft ein Verfahren zur Nutzbarmachung der bei der stufenweisen Verflüssigung der Luft auftretenden Wärme, welches sich dadurch auszeichnet, daß einerseits die Kompressionswärme und andererseits ein Teil der spezifischen Wärme in mechanische Arbeit umgesetzt wird, und zwar in der Weise, daß man sie auf leicht flüchtige Flüssigkeiten wie Äthylen, Kohlensäure u. dgl.The invention relates to a method for utilizing the in the stepwise Liquefaction of the air occurring heat, which is characterized in that on the one hand the heat of compression and on the other hand a part of the specific heat in mechanical Work is implemented, in such a way that you can use it on volatile liquids such as ethylene, carbonic acid and the like.

ίο überträgt und so die letzteren zur Leistung von Maschinenarbeit zwingt.ίο transmits and so the latter to performance of machine work forces.

Bei' der vorliegenden Erfindung wird auf eine gleichzeitige bedeutende Vorkühlung der Luft Gewicht gelegt; denn z. B. bei gewöhnlichem Maschinendruck siedende Kohlensäure hat immer noch eine Temperatur von etwa 30 bis 400 unter Null und ist also deshalb sehr wohl geeignet, die hindurchstreichende ,Luft vorzukühlen. Am besten läßt sich die einerseitige Vergasung der. Kohlensäure und die anderseitige Kühlung der zu verflüssigenden komprimierten Luft bei Anwendung des Gegenstromprinzips durchführen. Bei Anwendung des Acethylens ist die Vorkühlung der Luft naturgemäß noch bedeutender.In the present invention, emphasis is placed on simultaneous significant pre-cooling of the air; because z. B. carbonic acid boiling at normal machine pressure still has a temperature of about 30 to 40 0 below zero and is therefore very well suited to precooling the air passing through it. The one-sided gasification of the. Carry out carbon dioxide and the other side cooling of the compressed air to be liquefied using the countercurrent principle. When using the acetylene, the pre-cooling of the air is naturally even more important.

Die Erfindung wird an der Hand der schematischen Darstellung auf der Zeichnung in einem Ausführungsbeispiel beschrieben.
Die atmosphärische Luft wird durch die Rohre α und
saugt, durchThe invention is described using the schematic representation in the drawing in an exemplary embodiment.
The atmospheric air is through the tubes α and
sucks, through

a1 des Kompressors C eingeden Filter F, Kohlensäureabscheider G und Wasserabscheider H von bekannter Konstruktion hindurchgetrieben. Der Kompressor, der durch irgendeine verfügbare Kraft angetrieben wird, preßt beim Rückgang des Kolbens die angesaugten Luftmengen auf etwa 4 bis 6 Atm. und treibt die Luft in das Rohr b hinein. Dieses Rohr b ist umschlossen von einem weiteren Rohr c. Beim Durchgang der Luft durch das Rohr b gibt sie ihre Kompressionswärme und einen Teil der spezifischen Wärme an das im Rohr c befindliche Kühlmittel, z. B. eine leichtflüchtige Flüssigkeit, ab. Nach erfolgter Kühlung geht die auf 6 Atm. komprimierte Luft durch Rohr d nach dem Kompressor D. Beim Rückgang des Kolbens wird die Luft mit Hilfe dieses Kompressors auf einen Druck von 30 oder mehr Atm. gebracht und dann in das Rohr e befördert. Gleichfalls wird auch hier wieder die komprimierte Luft durch dasselbe Kühlmittel, etwa Äthylen, gedrückt. Hier gibt sie ebenfalls ihre Kompressionswärme ab und gelangt dann durch die Rohre f und g in den Chlorcalciumbehälter /, in dessen oberem Teile sich Watte befindet. In diesem Behälter werden die Feuchtigkeit und fremde Beimischungen der Luft zurückgehalten. Die Luft wird von hier aus durch Rohr h in das engere Kupferrohr der Austauschvorrichtung hl unter einem Drucke von 30 und mehr Atm. gedrückt. a 1 of the compressor C is driven through a filter F, carbonic acid separator G and water separator H of known construction. The compressor, which is driven by any available force, presses the amount of air drawn in to around 4 to 6 atmospheres as the piston retracts. and drives the air into the tube b . This tube b is enclosed by a further tube c. When the air passes through the tube b , it gives its heat of compression and part of the specific heat to the coolant in the tube c, e.g. B. a volatile liquid. After cooling, it goes to 6 atm. compressed air through pipe d after compressor D. When the piston retracts, the air is raised to a pressure of 30 atm or more with the help of this compressor. brought and then conveyed into the tube e. Here, too, the compressed air is forced through the same coolant, such as ethylene. Here it also gives off its heat of compression and then passes through pipes f and g into the calcium chloride container /, in the upper part of which there is cotton wool. Moisture and foreign admixtures in the air are retained in this container. The air is from here through tube h into the narrower copper tube of the exchange device h l under a pressure of 30 atm and more. pressed.

Nachdem die Luft am unteren Ende des Austauschers vor dem Entspannungsventil i angelangt ist, findet hier die Entlastung der Luft aul 4 bis 6 Atm. statt, indeß der Luftstrahl gegen die Flügel der angeordneten Turbine k tritt. Durch Rohr ρ geht dann die auf 4 bis 6 Atm. entspannte Luft, nachdem sie in der Austauschvorrichtung ihre Kälte abgegeben hat, nach dem Kompressor B. After the air has reached the lower end of the exchanger in front of the expansion valve i , the air is relieved from 4 to 6 atmospheres. instead, indeß the air jet against the blades of the arranged turbine k occurs. The tube ρ then goes to 4 to 6 atm. relaxed air after it has given off its cold in the exchange device, after the compressor B.

ίο Dieser saugt sie ein und drückt sie durch Rohr r auch hier durch die leicht flüchtige Flüssigkeit auf 30 oder mehr Atm. Die vom Kompressor B gedrückten Luftmengen vereinigen sich dann durch Rohr gl mit der durch die Kompressoren C und D gedrückten Luft. Beide komprimierteLuftmengen strömen gemeinsam in die Austauschvorrichtung P, und der Kreislauf beginnt von neuem.ίο This sucks it in and presses it through the pipe r here too through the volatile liquid to 30 or more atmospheres. The amounts of air pressed by compressor B then combine through pipe g l with the air pressed by compressors C and D. Both quantities of compressed air flow together into the exchange device P and the cycle begins again.

Die flüssige Luft sammelt sich in dem unteren Teile des Gehäuses der Turbine k an und kann durch den Hahn s abgelassen werden.The liquid air collects in the lower part of the housing of the turbine k and can be discharged through the cock s.

Zwecks genügender Vorkühlung der Luft und Nutzbarmachung der bei der Durchführung des Verfahrens entstehenden Wärme ist eine Anlage mit der eigentlichen Luftverflüssigungsvorrichtung verbunden, die mit Hilfe leicht flüchtiger Flüssigkeiten gestattet, einesteils die zu verflüssigende Luft stark vorzukühlen, andererseits aber einen großen Teil der bei der Luftverflüssigung freiwerdenden Kompressiöns- und spezifischen Wärme in mechanische Arbeit umzusetzen.For the purpose of sufficient pre-cooling of the air and utilization of the during implementation The heat generated during the process is a system with the actual air liquefaction device connected, which with the help of volatile liquids allows, on the one hand, the air to be liquefied to be strong to pre-cool, but on the other hand a large part of that released during air liquefaction Converting compression and specific heat into mechanical work.

Die in den Rohren t, c und u befindliche," durch den Stutzen ν und die Rohre w1, w*1 und n>% eingeführte flüchtige Flüssigkeit, beispielsweise Äthylen, Kohlensäure mit schwefliger Säure, verdampft durch' die im inneren Rohr b, e und r hindürchstreichende komprimierte erhitzte Luft. Letztere wird dadurch gleichzeitig stark vorgekühlt. Die entwickelten je nach der Art der angewandten flüchtigen Flüssigkeit auf 6 bis 20 Atm. gespannten, Dämpfe ziehen durch das Rohr χ, den Windkessel E und das Rohr y nach dem Kraftzylinder A, hier Arbeit verrichtend. Die durch die Arbeitsleistung entspannten und abgekühlten Gase der flüchtigen Flüssigkeit strömen dann durch das Rohr \, verflüssigen sich dann in dem Kondensator S, werden dann durch die Pumpe R angesaugt und vermittels des Rohrs ^1 in die Verdampfungsrohre t, c und u zurückgedrückt, um den Kreislauf von neuem zu beginnen.
·., Das Rohr η des Austauschers besteht aus Blei, entgegen der bis jetzt vorgeschlagenen und durchgeführten Verwendung von Kupfer. Blei ist wohlfeiler und leitet die Wärme schlechter. Das innere Rohr h1 ist jedoch aus Kupfer gefertigt, um guten Wärmeaustausch zu erzielen.The volatile liquid, for example ethylene, carbonic acid with sulphurous acid, which is in the pipes t, c and u , "introduced through the nozzle ν and the pipes w 1 , w * 1 and n> % , evaporates through the in the inner pipe b, e and r passing through compressed, heated air. The latter is thereby strongly pre-cooled at the same time. Depending on the type of volatile liquid used, the developed vapors, which are tensioned to 6 to 20 atm., pass through the pipe χ, the air chamber E and the pipe y after the power cylinder A, doing work here. The gases of the volatile liquid, relaxed and cooled by the work, then flow through the tube , then liquefy in the condenser S, are then sucked in by the pump R and through the tube ^ 1 into the evaporation tubes t, c and u pushed back to start the cycle again.
·., The tube η of the exchanger is made of lead, contrary to the previously proposed and implemented use of copper. Lead is cheaper and conducts heat more poorly. However, the inner tube h 1 is made of copper in order to achieve good heat exchange.

Die ganze Vorrichtung wird durch irgendeine verfügbare Kraftquelle angetrieben. Die gegen Wärmeaufnahme zu schützenden Teile werden mit Filz, Schafwolle u. dgl. verpackt. Der Hohlraum bei den Kompressoren B, C und D, in welchem die ineinandergesteckten Kupferverdampfungsrohre liegen, wird zweckmäßig mit einer Flüssigkeit ausgefüllt, die imstande ist, die Wärme schnell zu übertragen. "The whole device is powered by any available power source. The parts to be protected against heat absorption are packed with felt, sheep's wool and the like. The cavity in the compressors B, C and D, in which the nested copper evaporation tubes are located, is expediently filled with a liquid that is able to transfer the heat quickly. "
