Abstract
Um gasförmige oder flüssige Medien, wie beispielsweise gasförmiges oder flüssiges Kohlendioxid zu kühlen, kommen üblicherweise Kälteaggregate zum Einsatz, die allerdings aufgrund des Leistungsbedarfs sehr teuer in Beschaffung und Unterhaltung sind. Erfindungsgemäß wird das zu kühlende Medium durch einen Wärmetauscher geführt, der mit einem Bad aus einem kryogenen Kühlmedium, insbesondere Kohlendioxid thermich verbunden ist. Das Bad ist in einem isolierten Behälter aufgenommen, in den das Kühlmedium unter hohem Druck im flüssigen Zustand an einem Entspannungsventil eingedüst wird. Der Behälter ist mit einem Druckventil ausgerüstet, mittels dessen der Druck im Behälter, und somit der Enddruck der Entspannung des Kühlmediums und somit die Temperatur des Bades eingestellt werden kann. Auf diese Weise kann die Kühltemperatur der zu kühlenden Flüssigkeit in einem weiten Bereich eingestellt werden. Einer mit Fremdenergie betriebenen Anlage bedarf es nicht.In order to cool gaseous or liquid media such as gaseous or liquid carbon dioxide, refrigeration units are usually used, which, however, are very expensive to procure and maintain due to the power requirements. According to the invention, the medium to be cooled is passed through a heat exchanger which is thermally connected to a bath of a cryogenic cooling medium, in particular carbon dioxide. The bath is housed in an insulated container into which the cooling medium is injected under high pressure in the liquid state at an expansion valve. The container is equipped with a pressure valve, by means of which the pressure in the container and thus the final pressure of the expansion of the cooling medium and thus the temperature of the bath can be adjusted. In this way, the cooling temperature of the liquid to be cooled can be set over a wide range. A system operated with external energy is not required.
Description
Die Erfindung betrifft eine Vorrichtung zum Kühlen von flüssigen oder gasförmigen Medien.The The invention relates to a device for cooling liquid or gaseous media.
Tiefsiedende verflüssigte Gase können nur durch besonders gute Isolation der Speicherbehälter und der Rohrleitungen flüssig gehalten werden. Schon die geringste Wärmeeinstrahlung oder Reibungswärme kann je nach Siedezustand zu einer Teilverdampfung führen. Die Siedebläschen sammeln sich außer im Kopfraum des Speicherbehälters z.B. auch in senkrechten Rohrkrümmern. Diese sogenannten Gaspolster in der Versorgungsleitung führen zu Störungen an der Entnahmestelle, wenn eine reproduzierbare Dosierung des verflüssigten Gases gefordert wird. Es ist leicht einzusehen, dass durch eine gleich große Öffnung in gleichen Zeitintervallen wegen des Dichteunterschiedes zwischen Gas und Flüssigkeit unterschiedliche Mengen strömen. Um nun zuverlässig reine Flüssigkeit vor dem Dosierorgan anstehen zu haben, muss man das verflüssigte Gas gegenüber seinem jeweiligen Siedezustand unterkühlen.low boiling liquefied Gases can only by particularly good isolation of the storage tank and the pipes are liquid being held. Even the slightest heat or frictional heat can Depending on the boiling state lead to a partial evaporation. Collect the boiling bubbles except in the headspace of the storage container e.g. also in vertical pipe bends. These so-called gas cushions in the supply line lead to disorders at the sampling point, if a reproducible dosage of the liquefied Gas is required. It is easy to see that through a equal opening in same time intervals because of the density difference between Gas and liquid flow different amounts. To be reliable now pure liquid Before you have to wait before the dosing, you have the liquefied gas across from subcool its respective boiling state.
Eine solche Unterkühlung lässt sich beispielsweise dadurch bewerkstelligen, dass das flüssige Kühlmittel isobar mittels eines elektrischen Kühlaggregates so weit unterkühlt wird, dass bei der Umwälzung in einem Ringleitungssystem durch Wärmeeinstrahlung und Reibungsverluste keine Teilverdampfung auftritt. Die hierzu notwendigen Aggregate sind jedoch aufgrund ihres hohen Leistungsbedarfs sehr teuer in Anschaffung und Betrieb.A such hypothermia let yourself For example, accomplish that the liquid coolant Isobar is cooled down so far by means of an electric cooling unit, that during the upheaval in a loop system due to heat radiation and friction losses no partial evaporation occurs. The necessary aggregates are However, due to their high power requirements very expensive to purchase and operation.

Ein Nachteil dieser Ausgestaltung ist, dass die Bandbreite der Temperatureinstellung sehr schmal ist.One Disadvantage of this embodiment is that the bandwidth of the temperature setting is very narrow.
Der Erfindung liegt daher die Aufgabe zu Grunde, eine Vorrichtung zum Kühlen von fluiden Medien, insbesondere zum Unterkühlen von Flüssigkeiten zu schaffen, mit der auf einfache Weise eine hohe Bandbreite der Temperatureinstellung erreicht werden kann.Of the The invention is therefore based on the object, a device for Cool of fluid media, in particular for subcooling liquids, with in a simple way, a high bandwidth of the temperature setting can be achieved.
Gelöst wird diese Aufgabe durch eine Vorrichtung zum Kühlen von flüssigen oder gasförmigen Medien, mit einem in einem isolierten Behälter angeordneten Wärmetauscher, der von dem zu kühlenden Medium durchströmt wird und der in einem Bad aus einem Kühlmedium aufgenommen ist, mit einem in das Innere des isolierten Behälters an einem Entspannungsorgan ausmündenden Druckleitung für das Kühlmedium und mit einer mit einem Druckregelventil zur Einstellung des Drucks im Behälter ausgerüsteten Ausgangsleitung für das Kühlmedium.Is solved this object by a device for cooling liquid or gaseous media, with a heat exchanger arranged in an insulated container, that of the medium to be cooled flows through is and is taken in a bath of a cooling medium, with one in the interior of the insulated container at a relaxation organ opening out Pressure line for the cooling medium and one with a pressure regulating valve for adjusting the pressure in the container equipped Output line for the cooling medium.
Durch die Entspannung des Kühlmediums beim Eintritt in den Behälter sinkt die Temperatur des Kühlmediums aufgrund des Joule-Thomson-Effektes. Die Höhe des bei der Entspannung auftretenden Druckabfalls wird vom Druck des zugeführten Kühlmediums und vom frei einstellbaren Druckhaltewert am Druckregelventil in der Ausgangsleitung bestimmt. Zusammen mit dem zusätzlichen Parameter der der Temperatur des zugeführten Kühlmediums vor der Entspannung kann somit eine vorgegebene Temperatur im Kühlmediumsbad eingestellt werden. Unabhängig von einer Fremdkühlung kann so ein gasförmiges oder flüssiges Medium durch Wärmetausch mit dem Kühlmediumsbad gekühlt werden, wobei lediglich darauf geachtet werden muss, dass die Temperatur des Kühlmediumsbades im Innern des Behälters nicht so niedrig ist, dass das durch den Wärmetauscher geführte Medium einfriert.By the relaxation of the cooling medium during Entry into the container the temperature of the cooling medium drops due to the Joule-Thomson effect. The amount of relaxation occurring pressure drop is the pressure of the supplied cooling medium and the freely adjustable pressure holding value at the pressure regulating valve in the output line determined. Together with the additional Parameters of the temperature of the supplied cooling medium before the relaxation Thus, a predetermined temperature can be set in the cooling medium bath. Independent of a foreign cooling can be such a gaseous or liquid Medium by heat exchange with the cooling medium bath chilled only taking care that the temperature the cooling medium bath inside the container is not so low that the guided through the heat exchanger medium freezes.
Um die Temperatur des zugeführten Kühlmediums als weiteren freien Parameter nutzen zu können, ist es zweckmäßig, dass die Druckleitung vor ihrer Mündung am Entspannungsorgan eine Einrichtung zur Temperierung des Kühlmediums durchläuft. In vielen Fällen kommt es jedoch darauf an, dass das Kühlmedium bereits vor der Entspannung eine besonders tiefe Temperatur aufweist. In diesem Fall ist es besonders wirtschaftlich, wenn als Einrichtung zum Temperieren des Kühlmediums ein Wärmetauscher im Kühlmediumsbad vorgesehen ist. Das Kühlmedium wird also im eigenen Kühlmediumsbad vorgekühlt.Around the temperature of the supplied cooling medium to use as another free parameter, it is appropriate that the pressure pipe in front of its mouth on the relaxation device, a device for controlling the temperature of the cooling medium passes. In many cases However, it is important that the cooling medium already before the relaxation has a particularly low temperature. In this case it is Particularly economical, if as a means for tempering the cooling medium a heat exchanger in the cooling medium bath is provided. The cooling medium So it is in your own Kühlmediumsbad pre-cooled.
Um den Pegelstand im Innern des Behälters konstant zu halten und somit eine gleich bleibende Kühlung zu erzielen, ist zweckmäßigerweise eine Einrichtung zur Ermittlung des Füllstandes des Kühlmediumsbades vorgesehen, die mit einem in der Druckleitung für das Kühlmedium angeordneten Sperrorgan wirkverbunden ist. Bei Unterschreiten einer vorgegebenen Pegelhöhe öffnet sich das Sperrorgan der Druckleitung und flüssiges Kühlmedium strömt nach. Im einfachsten Fall handelt es sich bei der Einrichtung zur Ermittlung der Füllhöhe um ein schwimmergesteuertes Hebelventil. Freilich sind schwimmergesteuerte Ventile in der Praxis oft unzuverlässig, da die Dichte der stark siedenden Flüssigkeit im Behälter, und damit der Auftrieb für den Schwimmer, oftmals nicht ausreicht, um das Ventil zu schließen. Hinzu kommt, dass der Dichteunterschied zwischen Flüssigkeit und Gas nahe des kritischen Punktes immer geringer wird. Dies ist insbesondere bei Verwendung von Kohleindioxid als Kühlmittel von Bedeutung, da dieses häufig in der Nähe des kritischen Punktes eingesetzt wird. Zuverlässiger hat sich in solchen Systemen die Ermittlung von Füllständen mittels Widerstandsmessung oder Messung der Wärmeleitfähigkeit erwiesen. Bei diesen Messmethoden wird durch einen Vergleich dieser Parameter an mehreren, vertikal voneinander beabstandeten Punkten im Behälter auf den Aggregatszustand und damit die Füllhöhe geschlossen.In order to keep the level in the interior of the container constant and thus to achieve a constant cooling, a device for determining the level of the cooling medium bath is expediently provided, which is operatively connected to a arranged in the pressure line for the cooling medium blocking member. When falling below a predetermined level, the lock opens Organ of the pressure line and liquid cooling medium flows after. In the simplest case, the device for determining the filling height is a float-controlled lever valve. Of course, float-controlled valves are often unreliable in practice, as the density of the high-boiling liquid in the container, and thus the buoyancy for the float, often not sufficient to close the valve. In addition, the density difference between liquid and gas near the critical point is becoming smaller and smaller. This is particularly important when using carbon dioxide as a coolant, as this is often used in the vicinity of the critical point. In such systems, the determination of fill levels by means of resistance measurement or measurement of the thermal conductivity has proved to be more reliable. With these measuring methods, a comparison of these parameters at several, vertically spaced points in the container on the state of aggregation and thus the filling level is closed.
Zweckmäßigerweise ist eine Einrichtung zur Erfassung der Temperatur des gekühlten Mediums vorgesehen, die mit dem Duckregelventil wirkverbunden ist. Der Druck am Druckregelventil und damit die Temperatur des Kühlmediumsbades wird bei dieser erfindungsgemäßen Ausgestaltung kontinuierlich in Abhängigkeit von einer gewünschten Temperatur des behandelten Mediums eingestellt.Conveniently, a device for detecting the temperature of the cooled medium is provided, which is operatively connected to the pressure control valve. The pressure at the pressure control valve and thus the temperature of the cooling medium bath is in this embodiment of the invention continuously dependent from a desired one Adjusted temperature of the treated medium.
Ein bevorzugtes Kühlmedium ist Kohlendioxid. Kohlendioxid ermöglicht aufgrund seiner physikalischen Eigenschaften eine Einstellung der Temperatur des Kühlmediumsbades durch entsprechende Einstellung des Drucks in einem weiten Bereich zwischen +10°C und –55°C.One preferred cooling medium is carbon dioxide. Carbon dioxide allows due to its physical Features a setting of the temperature of the cooling medium bath by adjusting the pressure in a wide range between + 10 ° C and -55 ° C.
Besonders vorteilhaft eignet sich die erfindungsgemäße Vorrichtung zur Unterkühlung, also zur Abkühlung auf eine Temperatur deutlich unterhalb des Siedepunkts des eingesetzten kryogenen Mediums, beispielsweise von flüssigem Kohlendioxid. Durch Unterkühlung lassen sich insbesondere Kavitationseffekte bei Kolbenpumpen reduzieren. Bei der Erzeugung von Kohlendioxidschnee mittels Entspannung des flüssigen Kohlendioxids auf Umgebungsdruck lässt sich durch Unterkühlung zudem die Ausbeute, d.h. der Schneeanteil gegenüber dem Anteil an erzeugtem Kohlendioxidgas, erhöhen.Especially Advantageously, the device according to the invention is suitable for subcooling, ie for Cooling to a temperature well below the boiling point of the used cryogenic medium, for example of liquid carbon dioxide. By hypothermia In particular, cavitation effects in piston pumps can be reduced. In the production of carbon dioxide snow by means of relaxation of the liquid Carbon dioxide to ambient pressure can also by subcooling the yield, i. the proportion of snow compared to the proportion of generated Carbon dioxide gas, increase.
