Description

Zentrifugalabscheider  centrifugal

Die Erfindung richtet sich auf ein Verfahren zur Optimierung eines Zentrifugalabscheiders, insbesondere eines Rückführzyklons bei einem Hochtempera- turvergaser. The invention is directed to a method for optimizing a centrifugal separator, in particular a recycling cyclone in a high-temperature gasifier.

Zentrifugalabscheider sind in sehr unterschiedlichen Gestaltungen bekannt. So zeigt beispielsweise die DE 103 46 692 AI einen Tropfenabscheider, der im Übergang zum Trichterbereich außenrandseitig am dort endenden Tauchrohr Drallschaufeln aufweist, um im Trichter eine Rotation des eintretenden Gasstromes zu erreichen. Zu- und abschaltbare Zyklone zeigt beispielsweise die DE 102 05 981 AI, während die DE 195 16 817 Cl einen Zyklon mit zusätzlichen Elementen, wie beispielsweise eine Sprühelektrode, zeigt. Centrifugal separators are known in very different designs. For example, DE 103 46 692 A1 shows a droplet separator which, in the transition to the hopper area, has swirl vanes on the outside edge of the immersion pipe terminating there in order to achieve a rotation of the incoming gas flow in the hopper. For example, DE 102 05 981 A1 shows activation and deactivation of cyclones, while DE 195 16 817 C1 shows a cyclone with additional elements, such as a spray electrode.

Hochtemperaturvergaser wurden entwickelt, um mittels eines Wirbelschichtvergasungsprozesses die Nutzung beispielsweise von Braunkohle zu verbessern unter Nutzung eines sogenannten Hochtemperatur-Winkler-Vergasers HTW als Weiterentwicklung der ursprünglich bei Umgebungsdruck arbeitenden Winkler-Kohlevergasung . Die Vorteile liegen im Wesentlichen in der besseren Rohstoffnutzung, der erheblich größeren Vergaserkapazität für Großanlagen und in der Vermeidung der Bildung von Nebenprodukten. High-temperature gasifiers were developed to improve the use of, for example, lignite by means of a fluidized-bed gasification process using a so-called high-temperature Winkler gasifier HTW as a further development of Winkler coal gasification, which originally operated at ambient pressure. The advantages lie mainly in the better utilization of raw materials, the considerably larger carburetor capacity for large-scale plants and in the avoidance of the formation of by-products.

Nachteilig bei dieser Verfahrensweise ist u.a., dass die Abscheideeffizienz des Rückführzyklons nicht besonders ausgeprägt ist, was zur Folge hat, dass man kostenintensive Warmgasfilter hinter dem Zyklon und Rohgaskühler schalten muss. Erschwerend kommt noch hinzu, dass sich im Warmgasfilter abgeschiedenem Staub noch hohe Mengen an Kohlenstoff befindet. Dieser Staub kann somit nicht deponiert werden, sondern muss entweder zum Vergaser über Leitungen und Schnecken zurückgeführt werden oder mit hohem Aufwand in einem separaten Kessel mittels Hilfsbrennstoff verbrannt werden. A disadvantage of this procedure is, inter alia, that the separation efficiency of the recycling cyclone is not particularly pronounced, which has the consequence that you have to switch cost-intensive hot gas filter behind the cyclone and raw gas cooler. To make matters worse, that in the hot gas filter separated dust is still high amounts of carbon. This dust can thus not be landfilled, but must either be returned to the carburetor via lines and screws or burned at great expense in a separate boiler by means of auxiliary fuel.

Hier setzt die Erfindung ein, deren Aufgabe darin besteht, den Abscheidungs- grad eines Zentrifugalabscheiders, insbesondere eines Rückführzyklons bei einem Hochtemperaturvergaser, deutlich zu erhöhen. This is where the invention comes in, the object of which is to significantly increase the degree of separation of a centrifugal separator, in particular of a recycling cyclone in a high-temperature gasifier.

Mit einem Verfahren der eingangs bezeichneten Art wird diese Aufgabe gemäß einer Variante der Erfindung dadurch gelöst, dass durch Einbauten am Tauchrohr des Zentrifugalabscheiders eine lokale Erhöhung der Zentrifugalkraft vorgenommen wird . With a method of the type described, this object is achieved according to a variant of the invention in that a local increase in the centrifugal force is made by internals on the dip tube of the centrifugal.

Zur Erhöhung der Abscheideleistung eines Zyklons ist schon vorgeschlagen worden, das Tauchrohr in den "Totwasserbereich" zu verschieben, d .h. das Tauchrohr wird exzentrisch im Zyklon eingebaut. Eine solche Maßnahme ist nur bei Neubauten der Zyklone wirtschaftlich sinnvoll . Eine Nachrüstung und damit nachträgliche Optimierung ist damit wirtschaftlich nicht erreichbar. Die Einbauten am Tauchrohr lassen sich demgegenüber problemlos auch nachrüsten. To increase the separation efficiency of a cyclone has already been proposed to move the dip tube in the "dead water", ie. the dip tube is installed eccentrically in the cyclone. Such a measure makes economic sense only in new buildings of cyclones. A retrofit and thus subsequent optimization is therefore not economically feasible. The internals on the dip tube can be easily retrofitted.

Eine Variante der Optimierungsmöglichkeit besteht erfindungsgemäß darin, dass durch eine Vorschaltung eines Agglomerators im Eintrittsbereich des Zentrifugalabscheiders eine mechanische Kornvergrößerung der abzuscheidenden Partikel vorgenommen wird . Durch einen Agglomerator wird Einfluss auf die Partikelgröße genommen, indem eine Erhöhung der Kollisionsrate zwischen großen und kleinen Partikeln im Eintrittsbereich des Zyklons erreicht wird, was den Abscheidungsgrad deutlich verbessert. Grundsätzlich sind Agglomationsvorrichtungen bekannt, siehe dazu beispielsweise die DE A variant of the optimization option according to the invention consists in the fact that a mechanical grain enlargement of the particles to be separated is carried out by an upstream connection of an agglomerator in the inlet region of the centrifugal separator. An agglomerator influences the particle size by increasing the collision rate between large and small particles in the inlet area of the cyclone, which significantly improves the degree of separation. Basically agglomeration devices are known, see for example the DE

198 15 976 AI . 198 15 976 AI.

Da Zyklone nur in eng begrenzten Betriebszuständen optimal arbeiten, bei- spielsweise beträgt bei Stäuben eine optimale tangentiale Eintrittsgeschwindigkeit in den Zyklon 10 m/s, ist die Leistungsfähigkeit bei Lastwechseln Schwankungen unterworfen. Hier greift bei der Optimierung eines derartigen Zyklons die Erfindung durch Querschnittsveränderung am Zentrifugalabscheidereintritt ein, wobei diese Querschnittsveränderung in sehr unterschiedlicher Weise erfolgen kann, wie weiter unten angegeben. Since cyclones work optimally only in very limited operating conditions, For example, with dusts an optimal tangential entry velocity into the cyclone is 10 m / s, the performance is subject to fluctuations during load changes. Here, when optimizing such a cyclone, the invention intervenes by changing the cross section of the Zentrifugalabscheidereintritt, said cross-sectional change can be done in very different ways, as indicated below.

Mit der variablen Querschnittsveränderung wird erreicht, dass die Auslegungsgeschwindigkeit des Zyklons immer konstant gehalten werden kann. With the variable cross-sectional change is achieved that the design speed of the cyclone can always be kept constant.

In Ausgestaltung ist nach der Erfindung vorgesehen, dass mehrere der oben genannten Verfahrensschritte gleichzeitig vorgenommen werden. In an embodiment, it is provided according to the invention that several of the above-mentioned method steps are performed simultaneously.

Zur Lösung der gestellten Aufgabe sieht die Erfindung auch eine Vorrichtung bzw. einen Zentrifugalabscheider vor, der sich dadurch auszeichnet, dass am Tauchrohr ein den Strömungskanal des Zentrifugalabscheiders verengendes Strömungsleitelement vorgesehen ist. Ein solches verengendes Strömungselement kann, wie dies die Erfindung vorsieht, als schalenförmiges Leitblech ausgebildet sein. In order to achieve the object, the invention also provides a device or a centrifugal separator, which is characterized in that a flow-guiding element narrowing the flow channel of the centrifugal separator is provided on the dip tube. Such a narrowing flow element may, as the invention provides, be designed as a cup-shaped guide plate.

Um eine besonders optimale Strömung zu erreichen, kann dabei nach der Erfindung auch vorgesehen sein, dass am Außenbereich des Tauchrohres das exzentrische, schalenförmige Leitblech dem Gaseintritt etwa gegenüberliegend angeordnet ist, wobei das Leitblech bis unterhalb der Unterkante des Gaseintrittskanales gezogen und sich dann zum unteren Tauchrohrende der Rohrform verjüngend wieder angleicht. Die Position des Leitbleches kann je nach Auslegung des Zentrifugalabscheiders auch variieren. In order to achieve a particularly optimal flow, it can also be provided according to the invention that the eccentric, shell-shaped baffle is arranged approximately opposite the gas inlet at the outer region of the dip tube, the baffle pulled to below the lower edge of the gas inlet channel and then to the lower dip tube end rejuvenating the pipe shape. The position of the baffle may also vary depending on the design of the centrifugal separator.

Um eine mechanische Kornvergrößerung der Partikel zu erreichen, ist ein Agglomerator am Eintritt des Zentrifugalabscheiders erfindungsgemäß vorgesehen, der von einer Mehrzahl den Strömungskanal durchsetzenden rohrför- migen Strömungsstörelementen gebildet ist. Diese rohrförmigen Strömungsstörelemente können horizontal, vertikal oder im Winkel in den Strömungskanal eingebaut sein. In order to achieve a mechanical grain enlargement of the particles, an agglomerator is provided according to the invention at the inlet of the centrifugal separator, which is supported by a plurality of tubular conveyors passing through the flow channel. mige Strömungsstörelementen is formed. These tubular Strömungsstörelemente can be installed horizontally, vertically or at an angle in the flow channel.

Um, wie oben schon angegeben, die Auslegungsgeschwindigkeit des Zentrifugalabscheiders auch bei Lastwechseln konstant halten zu können, sieht die Erfindung in weiterer Ausgestaltung auch vor, dass der Eintrittströmungskanal mit einer den Kanalquerschnitt verändernden beweglichen Wandfläche oder einer keramischen Schieberplatte ausgerüstet ist, wobei Ausgestaltungen darin bestehen können, dass die horizontal oder vertikal bewegliche Wandfläche als Schieber oder als im Übergangsbereich zur Zentrifuge gekrümmtes Wandelement ausgebildet ist. In order to be able to keep the design speed of the centrifugal separator constant even during load changes, the invention also provides, in a further embodiment, for the inlet flow channel to be equipped with a movable wall surface or a ceramic slide plate which changes the channel cross-section, with embodiments being able to consist therein in that the horizontally or vertically movable wall surface is designed as a slide or as a wall element curved in the transition region to the centrifuge.

Weitere Merkmale, Einzelheiten und Vorteile der Erfindung ergeben sich aufgrund der nachfolgenden Beschreibung sowie anhand der Zeichnung. Diese zeigt in Further features, details and advantages of the invention will become apparent from the following description and from the drawing. This shows in

In Fig. 1 ist vereinfacht ein System einer Hochtemperatur-Winkler-Vergasung dargestellt mit einem Vergaser 1, dem über Vorlagebehälter 2 das Einsatzmaterial zugeführt wird. Das Bodenprodukt wird bei 3 ausgetragen, z. B. mittels einer Förderschnecke 4. Das Gas beaufschlagt einen Zentrifugalabscheider 5, wobei die Feststoffpartikel über die Leitung 6 wieder zurück in den Vergaser 1 geleitet werden, das Gas wird zur weiteren Bearbeitung über eine Leitung 7 abgeführt. In den Fig. 2 bis 7 sind Varianten der Einflussnahme auf die Strömung im Zentrifugalabscheider 5 dargestellt: In Fig. 1, a system of high-temperature Winkler gasification is shown in simplified form with a carburetor 1, the feed material is supplied via feed tank 2. The bottom product is discharged at 3, z. B. by means of a screw conveyor 4. The gas acts on a centrifugal separator 5, wherein the solid particles are passed via the line 6 back into the carburetor 1, the gas is removed for further processing via a line 7. In FIGS. 2 to 7, variants of the influence on the flow in the centrifugal separator 5 are shown:

Fig. 2 zeigt die Zuführung des Gemisches aus Feststoffen und Gasen (Pfeil 8) in den Zentrifugalabscheider 5, wobei das Gemisch das Tauchrohr 9 umströmt. Fig. 2 shows the supply of the mixture of solids and gases (arrow 8) in the centrifugal separator 5, wherein the mixture flows around the dip tube 9.

Zur Beschleunigung der Strömung weist das Tauchrohr 9 ein Strömungsleitelement 10 auf, das als gekrümmtes Leitblech auf das Tauchrohr 9 aufgeschweißt ist oder in anderer Weise dort befestigt ist. Wie sich aus Fig . 2 ergibt, verjüngt sich das Leitblech 10, in seinem unteren Bereich mit 10a bezeichnet, derart, dass am Ende des Tauchrohres 9 die ursprüngliche Querschnittsfläche des Strömungskanales wieder erreicht ist. Das gereinigte Gas verlässt den Zentrifugalabscheider 5 über das Rohr 7, was durch einen Pfeil 11 angedeutet ist. Die Feststoffpartikel verlassen den Abscheider nach unten, was durch einen Pfeil 12 angedeutet ist. To accelerate the flow, the dip tube 9 has a flow guide 10, which is welded as a curved baffle on the dip tube 9 or otherwise secured there. As can be seen from FIG. 2, the baffle 10 tapers, designated in its lower part with 10a, such that at the end of the dip tube 9, the original cross-sectional area of the flow channel is reached again. The cleaned gas leaves the centrifugal separator 5 via the pipe 7, which is indicated by an arrow 11. The solid particles leave the separator down, which is indicated by an arrow 12.

Die Position des Leitbleches 10 mit Verjüngung 10a ist in Fig . 2 zur besseren Darstellung an der vorgesehenen Stelle wiedergegeben . Diese muss nicht der echten Einbauposition entsprechen. The position of the guide plate 10 with the taper 10a is shown in FIG. 2 reproduced for better representation at the intended location. This does not have to correspond to the actual installation position.

Im Ausführungsbeispiel der Fig. 4 kann der Querschnitt des Eintrittskanales 14 in den Zentrifugalabscheider 5 durch ein anhebbares bzw. senkbares Sperr- element bzw. eine keramische Schieberplatte 16 verändert werden. Diese Bewegung ist mit einem Doppelpfeil 17 angedeutet.
