Description
Die Erfindung bezieht sich auf eine Maschine und beschreibt das entsprechende Verfahren zur Separierung der schweren Komponente aus Gasen eines Gemisches aufgrund der zentrifugalen Beschleunigung, weiterhin kurz rekursive Zentrifuge genannt. Die Voraussetzung ist, dass alle anderen Gase des Gasgemisches eine kleinere Dichte als die zu separierende Komponente haben, wie etwa im Falle von Verbrennungsabgasen bei Autos, Heizungen oder Kraftwerken, wo Kohlendioxid aus den restlichen Abgasen separiert werden soll. Diese Beschreibung basiert auf der Beschreibung des Zusatzpatents 10 2008 012 158 mit dem Titel „Verbesserte Zentrifuge zur Separierung von Kohlendioxid aus Gasgemischen”. Um den Reinheitsgrad der separierten Gaskomponente bis auf etwa 100% zu steigern bzw. den Anteil dieser Gaskomponente im Restgas bis auf etwa 0% zu reduzieren und das auch bei größeren Durchsätzen und in kürzerer Zeit als im Falle der Basis-Erfindung, hat die vorliegende Erfindung einige Verbesserungen eingeführt.The invention relates to a machine and describes the corresponding method for separating the heavy component from gases of a mixture due to the centrifugal acceleration, further called short recursive centrifuge. The prerequisite is that all other gases of the gas mixture have a smaller density than the component to be separated, such as in the case of combustion exhaust gases in cars, heaters or power plants, where carbon dioxide is to be separated from the remaining exhaust gases. This description is based on the specification of the
Dies wird durch die Zentrifuge mit den Merkmalen des Anspruchs 1 erreicht. Die erste Verbesserung besteht darin, dass die erstmalig separierte Gasmenge, die einen höheren Anteil an der schweren Komponente als das ursprüngliche Gasgemisch hat, erneut der zentrifugalen Separierung zugeführt wird und zwar durch geeignete Durchbrüche in der Wand zwischen dem ringförmigen Sammelbehälter für Gas und der Zuführung für das ursprüngliche Gasgemisch, wobei das Gas durch den zentrifugal erzeugten Überdruck im ringförmigen Sammelbehälter in den primären Gasgemisch getrieben wird. Dies ermöglicht eine allmähliche Raffinierung der separierten schweren Gaskomponente durch wiederholte Zentrifugierung mittels derselben Zentrifuge, bis der beabsichtigte Konzentrationsgrad, z. B. auch 100% erreicht wird – deswegen die Bezeichnung rekursive Zentrifuge.This is achieved by the centrifuge with the features of
Die zweite Verbesserung besteht darin, dass das Restgas, ausgetreten aus der ersten zentrifugalen Kammer, zu einer weiteren zentrifugalen Kammer geführt wird, die höher auf der gemeinsamen Achse angeordnet ist, so dass eine weitere Menge der schweren Gaskomponente unter der Einwirkung der Zentrifugalkraft abgetrennt wird und in den gemeinsamen ringförmigen Sammelbehälter geführt wird. Je höher der Durchsatz des Gasgemisches durch die rekursive Zentrifuge ist, desto weniger Zeit bleibt für die Trennung der schweren Gaskomponente unter Einwirkung der Zentrifugalkraft. Aus dem Grund werden bei der Dimensionierung und Auslegung dieser Maschine weitere zentrifugale Kammern auf der gemeinsamen Achse hinzugefügt, bis es sicher ist, dass das aus der letzten zentrifugalen Kammer ausgetretene Restgas frei von der zu separierende schweren Gaskomponente ist. Die Anzahl der notwendigen, in Serie geschalteten zentrifugalen Kammern ist abhängig vom Durchsatz des Gasgemisches und der maximal zulässigen peripheren Geschwindigkeit der einzelnen zentrifugalen Kammern, abgeleitet von der Zugbelastung des verwendeten Baumaterials. Während die Eingänge zu den zentrifugalen Kammern in Serie geschaltet sind, sind die Ausgänge dieser parallel zum gemeinsamen ringförmigen Sammelbehälter geschaltet.The second improvement is that the residual gas leaked from the first centrifugal chamber is led to another centrifugal chamber located higher on the common axis, so that another amount of the heavy gas component is separated under the action of centrifugal force and is guided in the common annular collection container. The higher the flow rate of the gas mixture through the recentric centrifuge, the less time is left for the separation of the heavy gas component under the effect of centrifugal force. For this reason, when dimensioning and designing this machine, additional centrifugal chambers are added to the common axis until it is certain that the residual gas leaving the last centrifugal chamber is free of the heavy gas component to be separated. The number of centrifugal chambers required in series depends on the flow rate of the gas mixture and the maximum permissible peripheral velocity of the individual centrifugal chambers, derived from the tensile load of the building material used. While the inputs to the centrifugal chambers are connected in series, the outputs of these are connected in parallel with the common annular collection container.
Eine weitere Verbesserung besteht darin, dass die Durchbrüche in der Zuführungswand zwischen dem ringförmigen Sammelbehälter für Gas und die Zuführung für das ursprüngliche Gasgemisch (primäres Gasgemisch) ringförmig in dieser Wand und oberhalb der Höhenlinie, markiert durch den oberen Sensor für die schwere Gaskomponente, im ringförmigen Behälter plaziert sind. Dies ermöglicht, dass nur leichteres Gas mit weniger Anteil an der schweren Gaskomponente der rekursiven Zentrifugierung zugeführt wird und nur komplett reine schwere Gaskomponente im ringförmigen Sammelbehälter sich anhäufen kann.A further improvement is that the apertures in the feed wall between the annular collecting container for gas and the feed for the original gas mixture (primary gas mixture) annular in this wall and above the contour line, marked by the upper sensor for the heavy gas component, in the annular Containers are placed. This allows only lighter gas with less proportion of the heavy gas component to be fed to recursive centrifugation and only completely pure heavy gas component to accumulate in the annular reservoir.
Eine weitere Verbesserung besteht darin, dass das aus den einzelnen zentrifugalen Kammern ausgetretene Gas, das einen höheren Anteil an der schweren Gaskomponente hat, zum Stillstand mittels radial angeordneter Trennwände gebracht wird, die zwischen den einzelnen zentrifugalen Kammern angeordnet sind, um zu verhindern, dass die schwere Gaskomponente, befindlich im unteren Teil des ringförmigen Sammelbehälter, durch Verwirbeln verunreinigt wird.A further improvement consists in that the gas which has escaped from the individual centrifugal chambers and which has a higher proportion of the heavy gas component is brought to a standstill by means of radially arranged partition walls which are arranged between the individual centrifugal chambers in order to prevent the gas heavy gas component, located in the lower part of the annular collecting container, is contaminated by swirling.
