Description

Die: Erfindung bezieht sich auf einen mit einem indifferenten Gas, arbeitenden Absorptnonskälte,-apparat mirt einem Verdampfer, Kocher, Kandensator, einem .ausi einem äußeren Rohr und einem inneren Rohr bestehenden Gagtemperatwrwechsler und einem aus einer Rohrschlange bestehenden Absorber. Zwecks Vereinfachung der Rohrverbindung zwischen Gaistemperatwrwechsler und Absorber iist bereits. vorgeschlagen worden, dies. obere Ende des Absorbers, unmittelbar an das äußere Rohr des. Gastemperatwrwechsilers, anzuschließen, wobei jedbch der Gastemperaturwechsler nach wie vor räumlich getrennt vom Sammelgefäß für die reiche Lösung angeoirdnet ist. Zum Unterschied davon ist gemäß der vorliegenden Erfindung der Mantel des Gastemperaturwechslers unimittelbar mit diem Mantel des Sammelgefäßes verschweißt - und die Leitung für die vom Kocher kommende arme ,Lösung an das Außenrohr des Gastemperaturwechslers an einer Steller zwischen dem Sammelgefäß und der Anschlußstelle für die Absorberschlange angeschlossen, die als Überlauf für die in die Absorberschlange fließende arme Lösung ausgebildet ist.The: The invention relates to a gas with an inert gas, working cold absorption apparatus with an evaporator, stove, candensator, a gas temperature changer consisting of an outer tube and an inner tube and an absorber consisting of a pipe coil. In order to simplify the The pipe connection between the gas temperature exchanger and the absorber is already in place. suggested been this. upper end of the absorber, directly on the outer tube of the gas temperature heat exchanger, to be connected, but the gas temperature changer is still spatially separated is in the collection vessel for the rich solution. The difference is according to the present invention, the jacket of the gas temperature changer immediately welded to the jacket of the collecting vessel - and the pipe for the one from the cooker coming poor, solution to the outer pipe of the gas temperature changer on one actuator connected between the collecting vessel and the connection point for the absorber coil, designed as an overflow for the poor solution flowing into the absorber coil is.

Durch diese Anordnung wird gegenüber den bekannten Bauarten einte erhöhte Stabilität des. Apparates gewonnen, da der -verhältnismäßig kräftige Mantel des Gastemperaturwechslers. unmittelbar mit dem festen Sammelgefäß verbunden ist. Ferner ergibt sich der Vorteil, däß die vom Kocher kommende arme Lösung im Gegenstrom zu! dem. durch das. innere Rohr des Gastemperaturwechslers gehende kalte: reiche Gas strömt und, von diesem gekühlt wird;, ohne daß hierfür bosonderz Einrichtungen errforderlich sind.This arrangement unites compared to the known types increased stability of the. Apparatus gained because of the -relatively strong jacket of the gas temperature changer. is directly connected to the solid collection vessel. There is also the advantage that the poor solution coming from the digester is countercurrent to! to the. cold: rich. going through the inner tube of the gas temperature changer Gas flows and is cooled by this; without the need for bosonderz facilities are required.

Die Erfindung isst im folgenden näher beschrieben _ unter Hinweis auf in, dien Zeichnungen dargestellte' Ausführungsbeispiele.The invention is described in more detail below with reference to 'embodiments shown in the drawings.

Fig. i ist eine perspektivische Ansicht des Rohrverlaufes in einem Kälteapparat gemäß der Erfindung; F ig. 2 zeigt den entsprechenden Rohrverlauf teilweise im Schnitt, und In Fig. i ist der Gaseempieraturwechsler i in Form von zwei konzentrischen Rohren 9 und 1o ausgebildet und oben an den Verdampfter angeschlosisen, der gemäß der Zeichnung aus einem einzigen, in geeigneter Weise zu einer Schlange gebogenen Rohr B besteht. Das äußere Rohr oder dien Mantel 9 des Gastemperaturwechslers ist unten an dem Mantel des Sammelgefäßes 2 für die reiche Lösung angeschweißt. 'Mit 3 - ist die Absorbersch-lange bezeichnet, Das vom unteren Teil dies. Verdampfers 8 kommende reiche Gas strömt durch das innere Rohr 1o und wird in das Sammelgefäß 2 geleitet, während das arme Gas vom Absorber 3 nach oben durch den ringförmigen Zwischenraum i i zwischen den: Rohren 9 und io sowie durch das Verbindungsrohr 12 in den oberen Teil des Verdampfers geleitet wird. Die Absorberschlange 3 ist hei 4 direkt an dem Mantel 9 des Gastemper aturwechsilers angeschlossen. Auch die vom Kocher durch die Leitung 13, dien Flüssigkeitstemperatur--#vechsler 14 und das Rohr 7 kommende arme Lösung wird bei 5 in den; unteren Teil des. Gastemperaturwechs,lers, zwischen dem Sammelgefäß 2 und der Ansch@lußstelle 4 der Absorberschlange ,geleitet. Die Leitung für die reiche Lösung ist mit 15 bezeichnet.Fig. I is a perspective view of the pipe run in a refrigeration apparatus according to the invention; Fig. 2 shows the corresponding pipe run partially in section, and In Fig. I the gas temperature changer i is designed in the form of two concentric tubes 9 and 1o and connected at the top to the evaporator, which according to the drawing consists of a single tube B suitably bent into a snake. The outer tube or jacket 9 of the gas temperature changer is welded to the bottom of the jacket of the collecting vessel 2 for the rich solution. ' With 3 - the Absorbersch-long is designated, that of the lower part dies. The rich gas coming from the evaporator 8 flows through the inner tube 1o and is conducted into the collecting vessel 2, while the poor gas from the absorber 3 upwards through the annular space ii between the: tubes 9 and io and through the connecting tube 12 into the upper part of the Evaporator is passed. The absorber coil 3 is hot 4 connected directly to the jacket 9 of the Gastemper aturwechselilers. Also the poor solution coming from the digester through the line 13, the liquid temperature - # changer 14 and the pipe 7 is at 5 in the; lower part of the gas temperature change, between the collecting vessel 2 and the connection point 4 of the absorber coil. The line for the rich solution is labeled 1 5.

Die Verbindung zwischen den verschiedenen Leitungen ist deutlich aus Fig. 2 ersichtlich, in dien die in Fig. i bei 2 bis 15 gezeigten Teile mit 22 bis 35 bezeichnet sind. Aus Fig. 2 geht hervor, daß der ringförmige. Zwischenraum 31 in dem nach unten verlängerten Teil des Gastemperaturw echslers 21 als, Flüssigkeitssack für. die arme, durch .das Roher 27 aufsteigende Lösung dient und daß die Anschlußisitelle 24 für- die Absorberschlanpe 23 beim Niveau 36 einen Überlauf aus dem genannten Flüssigkeitssack in, die Absorberschlange 23 hinein bildet.The connection between the various lines is clearly visible Fig. 2 can be seen, in which the parts shown in Fig. I at 2 to 15 with 22 to 35 are designated. From Fig. 2 it can be seen that the annular. Space 31 in the downwardly extended part of the gas temperature changer 21 as a liquid bag for. the poor solution rising through .das raw 27 serves and that the connection point 24 for the Absorberschlanpe 23 at level 36 an overflow from the mentioned Liquid sack in, the absorber coil 23 forms into it.
