Patentanmeldung 11olidationsvorrichtung, vorzugsweise für Rauchgasentschwefelungsanlagenw' In neuerer Zeit werden vielfach Rauchgasentschwefelungs-Anlagen hinter Eohlekraftwerken und Müllverbrennungs-Anlagen installiert.Patent application for consolidation device, preferably for flue gas desulphurisation systems In recent times, flue gas desulphurization systems are often installed behind coal power plants and waste incineration plants installed.
Die Waschflüssigkeit enthält Kalkmilch und wird aufgrund der Berührung mit den S02 zu einer Flüssigkeit, die Ca603 (Calciumsulfit) beinhaltet.The washing liquid contains milk of lime and is due to the touch with the S02 to a liquid that contains Ca603 (calcium sulfite).
Calciumsultit ist eine thixotrope Masse, die nur in besonderen vorgesehenen Deponien abgelagert werden darf.Calcium sultite is a thixotropic mass that is only provided in special Landfills may be deposited.
Die Zielsetzung ist, das Rückstandsprodukt von CIS03 zu CaS04 zu oxidieren.The objective is to oxidize the residue product of CIS03 to CaS04.
Das ist daher bereits mit Erfolg durchgeführt worden.This has therefore already been done with success.
In einem Oxidationsbehälter, der aus einem Mittelrohr und einem umlagerten Behälter besteht, wird in das Mittelrohr Luft eingeblasen und die Oxidation erzeugt.In an oxidation tank, which consists of a central tube and a rearranged one Container, air is blown into the central tube and the oxidation is generated.
Es ist jedoch bekannt, und es hat sich auch gezeigt daß die Verweilzeit und die Druckhöhe, unter der die Oxidation, d.h. das Einwirken der Luft auf die CaSO3-Ionen stattfindet von wesentlicher Bedeutung ist.However, it is known and has been shown that the residence time and the pressure level below which the oxidation, i.e. the action of the air on the CaSO3 ions taking place is essential.
bus diesem Grunde wird erfindungsgemäß vorgeschlagen, einen Oxideur, der eine Vergrößerung der Verweilzeit garantiert und gleichzeitig eine Erhöhung des Wasser drucks auf das zu oxidierende Produkt ausübt, zu benutzen entsprechend beiliegender Zeichnung.For this reason it is proposed according to the invention to use an oxidizer, which guarantees an increase in the dwell time and at the same time an increase the water pressure exerts on the product to be oxidized, to be used accordingly enclosed drawing.
In der beiliegenden Zeichnung ist dargestellt: mit 1 der äußere Oxidationebehälter; mit 2 die Waschflüssigkeit im äußeren Oxidationsbehälter; mit 3 die Oxidationsstrecke, die auch als Mehrfach~ strecke ausgeführt sein ~#ann, d#h. Bündelrohre oder dergleichen; mit 4 die reine Waschflüssigkeitshöhe; mit 5 die Waschflüssigkeits-Oxidationslufthöhe 5 Oxidationsstreckenlänge; mit 6 der eingeschnürte Außenmantel des Oxidationsbehälters.In the accompanying drawing is shown: with 1 the outer oxidation tank; with 2 the washing liquid in the outer oxidation tank; with 3 the oxidation path, which can also be designed as a multiple route, i.e. Bundle tubes or the like; with 4 the pure washing liquid level; with 5 the washing liquid oxidation air level 5 oxidation path length; with 6 the constricted outer jacket of the oxidation tank.
Die Verlängerung der Oxidationsstrecke ergibt sich aus der natheuatischen Gleichung: Y Waschflüssigkeit 1 Höhe der Waschflüssigkeit #Waschflüssigkeit-Luft x Höhe der Oiidationsstrecke Durch diese erfindungsgenäße konstruktive Anordnung eines Orideurs werden eit geringstem Luftbedarf durch Einblasen der Luft bei 7 in Relation zu bekannten Osidationssorrichtungen die besten Oxidationswerte erzielt.The extension of the oxidation path results from the natural Equation: Y washing liquid 1 height of washing liquid # washing liquid-air x Height of the Oiidationsabschnitt By this inventive constructive arrangement of an orider can be achieved with the least amount of air by blowing in the air at 7 in In relation to known oscillation devices, the best oxidation values are achieved.
Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellte Ausbildungsforj beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne Jedoch von den Grundgedanken absuweichen, eine Oxidationsvorrichtung so zu bauen, daß sie einen Innen- und Außenrohrmantel besitzt oder mehrere Innen- und Außenrohrmäntel, wobei die Innen-oder die Außenrohre gegeneinander unterschiedlich hpoh angeordnet sind und entsprechend der Luftdruckhöhe eine entsprechende Luftwassersäule erzielen, so daß erfordernisgerecht die Verweilzeit durch die Höhe des Luftdrucks über die Oxidationsstreckenhöhe oder -Länge und den dazugehörigen erforderlichen Druck bestimmt werden kann.Of course, the invention is not limited to the above in detail The training format shown is limited, but there are numerous changes possible, however, without deviating from the basic idea, an oxidation device to be built in such a way that it has an inner and outer pipe jacket or several inner and outer tube jackets, the inner or outer tubes being different from one another hpoh are arranged and a corresponding column of air water according to the air pressure level Achieve, so that the dwell time as required by the level of the air pressure on the height or length of the oxidation path and the associated required Pressure can be determined.
