Abstract
Die Erfindung betrifft ein Verfahren sowie eine Anlage zur Reduktion von Stickoxiden staubhaltiger Abgase mittels eines SCR-Katalysators, wobei die Abgase vor Eintritt in den Katalysator durch Agglomeration von Staubpartikeln konditioniert werden. Auf diese Weise wird eine besonders wirksame und betaubhaltiger Abgase mittels eines SCR-Katalysators erreicht.The invention relates to a method and a system for the reduction of nitrogen oxides dust-containing exhaust gases by means of an SCR catalyst, wherein the exhaust gases are conditioned by agglomeration of dust particles before entering the catalyst. In this way, a particularly effective and betaubhaltiger exhaust gases is achieved by means of an SCR catalyst.
Description
Die Erfindung betrifft ein Verfahren sowie eine Anlage zur Reduktion von Stickoxiden (NOX) staubhaltiger Abgase mittels eines SCR-Katalysators. Derartige Abgase fallen beispielsweise in Brennanlagen für Zement oder Minerals sowie in der Kraftwerkstechnik an.The invention relates to a method and a system for the reduction of nitrogen oxides (NO x ) dust-containing exhaust gases by means of an SCR catalyst. Such exhaust gases are obtained, for example, in furnaces for cement or minerals and in power plant technology.
Das SCR-Verfahren zur NOX-Minderung erfordert bei einem vertretbaren Einsatz von Vanadium und Edelmetallen aufgrund der mitunter hohen Schwefelfrachten in den Abgasen Reaktionstemperaturen von über 280°C. Bei Zementbrennanlagen ist es daher in der Regel notwendig, den Katalysator direkt hinter dem Zyklonvorwärmer zu platzieren, da hier prozessbedingt Temperaturen von etwa 300 bis 380°C vorliegen. Leider weisen jedoch die Abgase an dieser Stelle eine extrem hohe Staubbeladung in der Größenordnung von 50 bis 150 g/Nm3 auf. Diese hohen Staubfrachten führen am Katalysator zu Betriebsproblemen durch Verstopfungen; sie können ferner auch die poröse Oberfläche des Katalysators deaktivieren. Da der Katalysator in der Regel fest im Reaktor montiert ist, gibt es nur begrenzte Möglichkeiten, ihn im Betrieb zu reinigen und zu reaktivieren.The SCR process for NO x reduction requires a reasonable use of vanadium and precious metals due to the sometimes high sulfur levels in the exhaust gases reaction temperatures above 280 ° C. In cement kilns, it is therefore usually necessary to place the catalyst directly behind the cyclone preheater, since here process-related temperatures of about 300 to 380 ° C are present. Unfortunately, however, the exhaust gases at this point on an extremely high dust load in the order of 50 to 150 g / Nm 3 . These high dust loads cause clogging problems at the catalytic converter; they may also deactivate the porous surface of the catalyst. Since the catalyst is usually fixedly mounted in the reactor, there are limited opportunities to clean it in operation and reactivate.
Um
Staubablagerungen auf der Oberfläche von High-Dust-Katalysatoren
zu entfernen, ist der Einsatz von Druckluftbläsern bekannt
(
In der Praxis zeigt sich jedoch, dass diese bekannten Verfahren vielfach, inbesondere bei der Herstellung von Zementklinker, nicht den gewünschten Reinigungseffekt gewährleisten.In In practice, however, it has been shown that these known methods often, especially in the production of cement clinker, not the desired one Ensure cleaning effect.
Der Erfindung liegt daher die Aufgabe zu Grunde, ein Verfahren sowie eine Anlage zu schaffen, die eine besonders wirksame und betrieblich zuverlässige Reduktion von Stickoxiden staubhaltiger Abgase mittels eines SCR-Katalysators ermöglichen.Of the The invention is therefore based on the object, a method and to create a facility that is particularly effective and operational Reliable reduction of nitrogen oxides from dusty exhaust gases allow by means of an SCR catalyst.
Diese Aufgabe wird bei dem erfindungsgemäßen Verfahren dadurch gelöst, dass die Abgase vor Eintritt in den Katalysator durch Agglomeration von Staubpartikeln konditioniert werden. Die erfindungsgemäße Anlage ist demgemäß durch eine dem Katalysator vorgeschaltete Konditionierstufe zur Agglomeration von in den Abgasen enthaltenen Staubpartikeln gekennzeichnet.These Task is in the inventive method solved by the fact that the exhaust gases before entering the catalyst conditioned by agglomeration of dust particles. The inventive system is accordingly by a conditioning stage upstream of the catalyst for agglomeration characterized by dust particles contained in the exhaust gases.
Wie die der Erfindung zu Grunde liegenden Versuche zeigten, hängt die Gefahr einer Verstopfung des Katalysators und einer Deaktivierung seiner porösen Oberfläche sehr eng mit der Größe der Staubpartikel zusammen. Sorgt man daher erfindungsgemäß für eine bestimmte Mindestgröße der Staubpartikel-Agglomerate, so können diese in der Regel ohne Betriebsprobleme durch den Katalysator geführt werden, da sie weder den Katalysator verstopfen, noch seine poröse Oberfläche deaktivieren. Auf diese Weise wird eine sehr wirksame und betrieblich zuverlässige Reduktion von Stickoxiden staubhaltiger Abgase mittels des SCR-Katalysators ermöglicht.As the experiments on which the invention was based depends the risk of clogging of the catalyst and deactivation Its porous surface is very close to the size the dust particles together. Is therefore provided according to the invention for a certain minimum size of the dust particle agglomerates, so these can usually be run through without any operational problems be carried out the catalyst since they neither the catalyst clog, still disable its porous surface. On This way will be a very effective and operationally reliable Reduction of nitrogen oxides dusty exhaust gases using the SCR catalyst allows.
Je nach Art des SCR-Katalysators sowie der Temperatur, des Staubgehaltes und des Volumenstromes der staubhaltigen Abgase liegt die anzustrebende mittlere Partikelgröße der Staubpartikel-Agglomerate bei mindestens 5 μm, vorzugsweise bei 8 bis 15 μm.ever the type of SCR catalyst and the temperature, the dust content and the volume flow of dusty exhaust gases is the desired mean particle size of the dust particle agglomerates at least 5 microns, preferably 8 to 15 microns.
Die Agglomeration von Staubpartikeln kann akustisch herbeigeführt werden, indem in einer staubhaltigen Abgas-Strömung Ultraschallwellen erzeugt werden.The Agglomeration of dust particles can be induced acoustically be in a dusty exhaust flow ultrasonic waves be generated.
Eine andere Möglichkeit besteht darin, die Agglomeration elektrostatisch herbeizuführen, indem wenigstens zwei staubhaltige Abgas-Teilströme gegensinnig elektrostatisch aufgeladen und dann zwecks Agglomeration von Staubpartikeln zusammengeführt werden.A Another possibility is to agglomerate electrostatically cause by at least two dust-containing exhaust gas streams electrostatically charged in opposite directions and then agglomerated be brought together by dust particles.
Diese und weitere Einzelheiten der Erfindung sind Gegenstand der Unteransprüche und werden im Zusammenhang mit der Beschreibung einiger Ausführungsbeispiele näher erläutert.These and further details of the invention are the subject of the dependent claims and in connection with the description of some embodiments explained in more detail.

Um hohe Agglomerationsraten zu erreichen, ist ein ausgewogenes Verhältnis zwischen der Staubbeladung der Abgase und der Ausbreitung der Schallwellen in der Konditionierstufe erforderlich. Die akustische Agglomeration erfolgt vorzugsweise mit einer Staubbeladung zwischen 3 und 30 g/Nm3, vorzugsweise zwischen 5 und 20 g/Nm3.In order to achieve high agglomeration rates, a balance between the dust load of the exhaust gases and the propagation of the sound waves in the conditioning stage is required. The acoustic agglomeration is preferably carried out with a dust loading between 3 and 30 g / Nm 3 , preferably between 5 and 20 g / Nm 3 .
Extrem hohe Staubbeladungen der Abgase, etwa zwischen 50 und 150 g/Nm3, können beispielsweise in der Zementindustrie auf der Gasaustrittsseite des Vorwärmers auftreten. Hier empfiehlt es sich, die Staubbeladung der Abgase vor der Staubagglomeration zunächst durch eine Vorentstaubung auf einen für die Staubagglomeration geeigneten Wert herabzusetzen. Als Hilfsmittel für eine solche Vorentstaubung eignen sich vor allem Zyklone aufgrund ihres einfachen Aufbaus und ihrer geringen Störungsanfälligkeit. Ein ohnehin vorhandener Zyklonvorwärmer der Zementbrennanlage kann also für den genannten Zweck der Vorentstaubung der Abgase um eine zusätzliche Stufe erweitert werden.Extremely high dust loads of the exhaust gases, for example between 50 and 150 g / Nm 3 , can occur, for example, in the cement industry on the gas outlet side of the preheater. Here it is advisable to reduce the dust load of the exhaust gases before the dust agglomeration by first dedusting to a suitable level for the dust agglomeration. As an aid for such dedusting are especially cyclones due to their simple structure and low susceptibility to interference. An existing anyway Zyklonvorwärmer the cement kiln can therefore be extended by an additional level for the purpose of the dedusting of the exhaust gases.
Auf dem Markt gibt es SCR-Katalysatortypen mit Platten- und Wabengeometrien sowie mit unterschiedlichen Kanaldurchmessern. Bei hoher Staubempfindlichkeit des Katalysators, wie sie insbesondere bei geringen Abmessungen der Strömungskanäle des Katalysators meist vorliegt, kann es zweckmäßig sein, den Staubgehalt der Abgase nach der Staubagglomeration, jedoch vor Zuführung der Abgase zum Katalysator, durch Abscheidung zumindest eines Teiles der gebildeten Staubpartikel-Agglomerate auf eine für den SCR-Katalysator geeigneten Wert herabzusetzen.On The market has SCR catalyst types with plate and honeycomb geometries as well as with different channel diameters. With high dust sensitivity of the catalyst, as in particular with small dimensions the flow channels of the catalyst is mostly present, it may be appropriate to the dust content of the exhaust gases after the dust agglomeration, but before feeding the exhaust gases to the catalyst, by deposition of at least a portion of the formed Dust particle agglomerates on one for the SCR catalyst reduce the appropriate value.
Die Vor- und die Nachentstaubung der Abgase mit Zyklonen steigern den Gesamtdruckverlust einer Anlage und erhöhen den Anlagenaufwand. Auf die Nachentstaubung durch einen Zyklon kann in Abhängigkeit der erforderlichen Reinheit auch bei staubempfindlichen Katalysatoren dann verzichtet werden, wenn die in der Konditionierstufe gebildeten Staubpartikel-Agglomerate zumindest teilweise bereits am Ausgang der Konditionierstufe abgeschieden werden.The Pre and post dedusting of the exhaust gases with cyclones increase the Total pressure loss of a system and increase the system cost. On the Nachentstaubung by a cyclone can depend on the required purity even with dust-sensitive catalysts are then waived if the dust particle agglomerates formed in the conditioning stage at least partially already deposited at the outlet of the conditioning stage become.

Im Gegensatz zur akustischen Agglomeration ist bei dieser elektrostatischen Agglomeration im allgemeinen keine Vorentstaubung erforderlich. Vorzugsweise erfolgt statt dessen eine Nachentstaubung. Wie weitgehend sie erfolgt, hängt von den Wechselwirkungen zwischen den Staubagglomeraten und dem Katalysator ab.in the Contrary to the acoustic agglomeration is with this electrostatic Agglomeration generally no pre-dedusting required. Preferably, instead of a Nachentstaubung. How far It takes place depends on the interactions between the Dust agglomerates and the catalyst from.
