Abstract
Description
Die Erfindung betrifft eine Anordnung zum Eintragen von Kohlendioxid im flüssigen Zustand in ein fluides Medium.The The invention relates to an arrangement for introducing carbon dioxide in the liquid state in a fluid medium.
Kohlendioxid wird für eine Vielzahl von Verfahren benötigt – etwa bei der chemischen Carbonisierung, zur Neutralisation von Abwässern oder bei der pH-Einstellung bei der Trinkwasseraufbereitung, bei der Schnellkühlung von Lebensmitteln und vielem mehr.carbon dioxide is needed for a variety of procedures - such as in chemical carbonation, for the neutralization of wastewater or in the pH adjustment in drinking water treatment, at the rapid cooling of food and much more.
Viele Verfahren betreffen die Anwendung von Kohlendioxid in flüssigen, schlickerartigen oder pastösen Stoffen. Häufig wird dabei das Kohlendioxid gasförmig in den zu behandelnden Stoff eingetragen. Der Gaseintrag ist jedoch häufig wenig effektiv und bedarf eines aufwändigen Aufbaus, um eine möglichst feine und homogene Verteilung des Gases in dem zu behandelnden Stoff zu erreichen.Lots Procedures concern the use of carbon dioxide in liquid, slurry or pasty substances. Often while the carbon dioxide is gaseous in the treated Substance registered. However, the gas input is often low effective and requires a complex construction to a as fine and homogeneous distribution of the gas in the to achieve the substance to be treated.
Alternativ
zum Eintragen in Gasform kommt die Behandlung mit festem Kohlendioxid
(Trockeneis) in Betracht. Beispielsweise ist aus der
Gegenüber den vorgenannten Eintragsarten ist der Eintrag von flüssigem Kohlendioxid in ein Medium nur schwer zu bewerkstelligen, da aufgrund des Tripelpunktes von Kohlendioxid bei etwa 5,18 bar flüssiges Kohlendioxid nur oberhalb dieses Wertes anwesend sein kann; fällt der Druck unter diesen Wert, geht das flüssige Kohlendioxid teilweise in Kohlendioxidschnee, teilweise in gasförmiges Kohlendioxid über. Findet der Übergang innerhalb der Kohlendioxidzuleitung statt, besteht so die Gefahr, dass die Zuleitung aufgrund des sich im Innern ansammelnden Kohlendioxidschnees blockiert wird.Across from the above entry types is the entry of liquid Carbon dioxide in a medium difficult to accomplish, due to the triple point of carbon dioxide at about 5.18 bar liquid Carbon dioxide can be present only above this value; falls the pressure below this value, the liquid carbon dioxide goes partly in carbon dioxide snow, partly in gaseous Carbon dioxide over. Find the transition within the carbon dioxide feed line instead, there is a risk that the supply line blocked due to the accumulation of carbon dioxide snow inside becomes.
Aufgabe der vorliegenden Erfindung ist somit, eine Möglichkeit zum Eintragen von flüssigem Kohlendioxid in ein fluides Medium zu schaffen, bei dem die Gefahr einer Vereisung durch Entstehung von Trockeneisschnee minimiert wird.task Thus, one possibility is the present invention for introducing liquid carbon dioxide into a fluid Medium to create, in which the risk of icing due to the emergence of Dry ice snow is minimized.
Gelöst ist diese Aufgabe durch eine Anordnung zum Eintragen von flüssigem Kohlendioxid in ein fluides Medium mit den Merkmalen des Patentanspruchs 1.Solved This object is achieved by an arrangement for introducing liquid Carbon dioxide in a fluid medium with the features of the claim 1.
Weitere Vorteilhafte Ausführungsformen sind in den Unteransprüchen angegeben.Further Advantageous embodiments are in the subclaims specified.
Erfindungsgemäß weist also eine Vorrichtung zum Eintragen von Kohlendioxid im flüssigen Zustand in ein fluides Medium eine Versorgungstank für flüssiges Kohlendioxid, eine mit dem Versorgungstank verbundene und an einem Eintragspunkt in eine fluidführende Leitung einmündende Druckleitung für flüssiges Kohlendioxid auf. In der Druckleitung ist, unmittelbar an der Einmündung der Druckleitung in die fluidführende Leitung ein Entspannungsorgan integriert, mittels dessen in einem zwischen Versorgungstank und Entspannungsorgan angeordneten Abschnitt der Druckleitung ein Druck oberhalb des Drucks des Tripelpunktes von Kohlendioxid aufrecht erhalten werden kann.According to the invention So a device for introducing carbon dioxide in the liquid state in a fluid medium a supply tank for liquid Carbon dioxide, one connected to the supply tank and attached to one Entry point in a fluid-conducting line opening Pressure line for liquid carbon dioxide on. In the pressure line is, directly at the confluence of Pressure line in the fluid-carrying line a relaxation organ integrated, by means of which in a between supply tank and Relaxation organ arranged portion of the pressure line a pressure upright above the pressure of the triple point of carbon dioxide can be obtained.
Die Lage des Entspannungsorgans möglichst unmittelbar an der Einmündung verhindert dabei, dass sich Kohlendioxidschnee, der sich bei der Entspannung bildet, in der Kohlendioxid-Zuleitung ansammeln kann. Zugleich wird gewährleistet, dass das Kohlendioxid zumindest zum Teil im noch flüssigen Zustand in das fluide Medium eingetragen wird und sich mit dem fluiden Medium vermischt. Als „fluides Medium” wird hier jedes fließfähige, flüssige, pastöse oder schlickerartige Medium verstanden. Der Druck in der fluidführenden Leitung kann mehr oder weniger als der Druck pt des Tripelpunktes von Kohlendioxid betragen. Der Eintrag von Kohlendioxid in flüssiger Form hat insbesondere den Vorteil, dass sich das Kohlendioxid sehr homogen im Medium verteilt; zudem entfällt der Aufwand, der zum Verdampfen und/oder Verfestigen des Kohlendioxids sowie zum Eintragen möglichst feiner Gasblasen oder Schneeteilchen erforderlich ist. Zudem führt die Entspannung des Kohlendioxids innerhalb des Mediums zu einer starken und in vielen Fällen gewünschten Kühlwirkung.The location of the relaxation organ as close as possible to the confluence prevents carbon dioxide snow, which forms during the expansion, from accumulating in the carbon dioxide feed line. At the same time it is ensured that the carbon dioxide is introduced at least partially in the still liquid state in the fluid medium and mixed with the fluid medium. As "fluid medium" is meant here any flowable, liquid, pasty or slurry-like medium. The pressure in the fluid-carrying line may be more or less than the pressure p t of the triple point of carbon dioxide. The entry of carbon dioxide in liquid form has the particular advantage that the carbon dioxide is distributed very homogeneously in the medium; In addition, eliminates the effort that is required for evaporation and / or solidification of carbon dioxide and for entering the finest possible gas bubbles or snow particles. In addition, the relaxation of carbon dioxide within the medium leads to a strong and in many cases desired cooling effect.
Eine
bevorzugte Ausgestaltung der Erfindung sieht vor, dass das Entspannungsorgan
derart ausgebildet ist, das unterhalb eines vorgegebenen Druckes
in der Druckleitung automatisch schließt. Unter „vorgegebenem
Druck” ist dabei ein Druck p1 zu
verstehen, der größer als der Druck pt des
Tripelpunkts von Kohlendioxid ist. Bei zu rascher Injektion des
Kohlendioxids wird so sicher gewährleistet, dass der Druck
in der Zuleitung nicht unter den Druck pt absinkt.
Ein geeignetes und bevorzugtes Element dieser Art wird in der
Besonders zweckmäßig ist es, das Entspannungsorgan als Rückschlagventil auszubilden, das das Eindringen von fluidem Medium in die Druckleitung verhindert.Especially It is expedient, the relaxation organ as a check valve form, which is the penetration of fluid medium in the pressure line prevented.
Weiter bevorzugt ist eine Anordnung, bei der das Rückschlagventil mit einem Ventilteller ausgerüstet ist, der im Schließzustand des Rückschlagventils auf einem von der fluidführenden Leitung abgewandten Seite des Ventiltellers angeordneten Ventilsitz dichtend aufsitzt und der durch druckgesteuertes Verschieben in Richtung der fluidführenden Leitung in seinen Öffnungszustand bringbar ist. Das Rückschlagventil öffnet sich dabei durch Verschieben des Ventiltellers in Richtung auf die fluidführende Leitung beispielsweise dann, wenn der Druck in der Druckleitung höher ist als ein vorgewählter Wert oberhalb des Tripelpunktes von Kohlendioxids ist. Dadurch wird ein Verstopfen des Ventils durch sich bildendes Eis im Fluid wirksam verhindert.Further preferred is an arrangement in which the check valve equipped with a valve plate, which in the closed state the check valve on one of the fluid-carrying Line facing away from the valve plate arranged valve seat sealingly seated and by pressure-controlled shifting in Direction of the fluid-carrying line in its open state can be brought. The check valve opens thereby by moving the valve disk in the direction of the fluid-carrying Line, for example, when the pressure in the pressure line is higher than a preselected value above the triple point of carbon dioxide is. This will clog the valve forming ice in the fluid effectively prevented.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, dass von der Druckleitung Zweigleitungen ausmünden, die mit gleichfalls mit einem Entspannungsorgan versehenen Eintragpunkten an mehreren voneinander beabstandeten Stellen in die fluidführende Leitung einmünden. Das flüssige Kohlendioxid wird in diesem Falle also mehrfach an voneinander beabstandeten Punkten in das gleiche Fluid eingetragen. Auf dieses Weise wird eine besonders effektiver Eintrag des Kohlendioxids gewährleistet.A advantageous development of the invention provides that of the Pressure line branches open out with the same provided with a relaxation organ entry points at several spaced locations in the fluid-carrying Open the line. The liquid carbon dioxide is in this case several times at spaced points entered in the same fluid. In this way, a special ensures effective input of carbon dioxide.
Eine andere zweckmäßige Weiterbildung der Erfindung sieht vor, dass von der Druckleitung Zweigleitungen ausmünden, die an gleichfalls mit einem Entspannungsorgan versehenen Eintragpunkten in mehrere unterschiedliche fluidführende Leitungen einmünden. Bei dieser Ausgestaltung können also mehrere Leitungen aus einem Kohlendioxidtank mit flüssigem Kohlendioxid versorgt werden. Selbstverständlich ist es im Rahmen der Erfindung auch denkbar, diese Ausführungsform mit der vorgenannten zu kombinieren, d. h. Zuführungen zu mehreren Leitungen oder Behältern und/oder mehrere Zuführungen in die gleiche Leitung vorzusehen.A other expedient development of the invention provides that branches of the pressure line the entry points also provided with a relaxation organ lead into several different fluid-carrying lines. In this embodiment, therefore, multiple lines supplied from a carbon dioxide tank with liquid carbon dioxide become. Of course, it is within the scope of the invention also conceivable, this embodiment with the aforementioned to combine, d. H. Feeds to multiple lines or containers and / or multiple feeds in to provide the same line.
Vorteilhafterweise sind in der Kohlendioxid-Zuleitung, stromauf zum Entspannungsventil, ein Mengenregelventil sowie eine Steuereinheit vorgesehen, welche den Mengendurchfluss am Mengenregelventil in Abhängigkeit von einem vorgegebenen Programm und/oder von physikalischen oder chemischen Parametern im Medium, regelt. Auf diese Weise gelingt eine besonders zuverlässige und genaue Eindosierung des flüssigen Kohlendioxids.advantageously, are in the carbon dioxide feed line, upstream to the expansion valve, a flow control valve and a control unit is provided, which the mass flow at the flow control valve in dependence from a given program and / or physical or chemical parameters in the medium, regulates. In this way succeeds a particularly reliable and accurate metering of the liquid carbon dioxide.
In einer einfachen und kostengünstigen Ausgestaltung ist das Mengenregelventil als Auf/Zu-Ventil ausgestaltet, d. h. das Ventil ist entweder vollständig geöffnet oder vollständig geschlossen.In a simple and inexpensive design that is Flow control valve designed as open / close valve, d. H. the valve is either fully open or complete closed.

Beim Einsatz der erfindungsgemäßen Anordnung wird ein Verstopfen von Leitungen mit Kohlendioxidschnee wirksam verhindert und somit bei niedrigen Investitionskosten eine gleichwohl wirkungsvolle Möglichkeit geschaffen, Kohlendioxid im flüssigen Zustand in ein Fluid einzubringen. Ein Verdampfer für das Kohlendioxid oder eine Eintragseinrichtung zum Einbringen des Kohlendioxids in Form möglichst feiner Gasblasen ist nicht erforderlich.At the Use of the arrangement according to the invention is a Clogging of pipes with carbon dioxide snow effectively prevented and thus at low investment costs, nevertheless an effective one Possibility created carbon dioxide in the liquid State in a fluid to bring. An evaporator for that Carbon dioxide or an entry means for introducing the carbon dioxide in the form of the finest possible gas bubbles is not required.
