Description

Die Erfindung richtet sich auf einen Vergasungsreaktor zur Herstellung von CO- oder H2-haltigem Rohgas der im Oberbegriff des Anspruches 1 angegebenen Gattung.The invention is directed to a gasification reactor for the production of CO- or H 2 -containing raw gas of the type specified in the preamble of claim 1.

Ein derartiger Vergasungsreaktor ist beispielsweise aus der WO 2009/036985 A1 der Anmelderin bekannt, wobei in dieser Literaturstelle eine Fülle von weiterem Stand der Technik genannt ist, wie beispielsweise die US 4 474 584 , die insbesondere die Kühlung des heißen Synthesegases behandelt.Such a gasification reactor is for example from the WO 2009/036985 A1 the applicant, in which reference a wealth of further prior art is called, such as the US 4,474,584 which deals in particular with the cooling of the hot synthesis gas.

Die Erfindung beschäftigt sich insbesondere mit Problemen, die bei derartigen Reaktoren auftauchen, wobei die Erfindung nicht auf den speziell hier angesprochenen Vergasungsreaktor beschränkt ist, sie richtet sich auch auf Apparate, bei denen ähnliche, weiter unten näher beschriebene Probleme auftauchen können.The invention is particularly concerned with problems encountered with such reactors, the invention being not limited to the gasification reactor specifically contemplated herein, but also directed to apparatuses in which similar problems, as described in more detail below, may arise.

Ein derartiger Apparat muss geeignet sein, um Verfahren der Druckvergasung/Verbrennung von fein verteilten Brennstoffen zu ermöglichen, wozu die partielle Oxidation der Brennstoffe Kohlenstaub, fein verteilte Biomasse, Öl, Teere od. dgl. in einem Reaktor gehört. Hierzu gehört auch der getrennte oder gemeinsame Abzug von Schlacke oder Flugasche und erzeugtem Synthese- bzw. Rauchgas. Es muss eine Kühlung der Reaktionsprodukte (Gas und Schlacke/Flugasche) möglich gemacht werden, etwa durch Sprühquenchen, Gasquenchen, Strahlungsquenchen, Konvektionsheizflächen od. dgl., je nach Art des eingesetzten Verfahrens, wobei schließlich auch ein Augenmerk auf die Ausschleusung der Reaktionsprodukte aus dem Druckbehälter gerichtet werden muss.Such an apparatus must be suitable to allow processes of pressure gasification / combustion of finely divided fuels, including the partial oxidation of the fuels coal dust, finely divided biomass, oil, tars or the like in a reactor. This includes the separate or joint withdrawal of slag or fly ash and produced synthesis or flue gas. It must be made possible cooling of the reaction products (gas and slag / fly ash), such as spray quenching, gas quenching, radiation quenching, Konvektionsheizflächen od. Like., Depending on the nature of the method used, which finally also pay attention to the discharge of the reaction products from the Pressure vessel must be addressed.

In der oben genannten WO 2009/036985 A1 wird eine Drallströmung erzeugt, um auch gröbere Partikel vollständig umsetzen zu können sowie kritische Bereiche der Heizflächen vor zu hoher Wärmestromdichte zu bewahren. Dies wird durch eine Brenneranstellung von 1 bis 20° in der Horizontalebene verwirklicht. Der erzeugte Drall muss nach Verlassen des Reaktors wieder aus der Strömung entfernt werden, damit die heißen, klebrigen Schlackepartikel nicht gegen die den Druckbehälter schützenden, ungeschützten Heizflächen geschleudert werden und dort Anbackungen oder Schäden zu verursachen.In the above WO 2009/036985 A1 a swirl flow is generated in order to be able to completely convert coarser particles as well as to protect critical areas of the heating surfaces from too high a heat flow density. This is achieved by a burner setting of 1 to 20 ° in the horizontal plane. The swirl generated must be removed from the flow again after leaving the reactor, so that the hot, sticky slag particles are not thrown against the pressure vessel protecting, unprotected heating surfaces and there to cause caking or damage.

Entsprechende Drallbremsen sind beispielsweise in der DE 10 2009 005 464.2 beschrieben.Corresponding swirl brakes are for example in the DE 10 2009 005 464.2 described.

Aufgabe der Erfindung ist die Schaffung einer Lösung, mit der zum einen eine Strähnenbildung der ablaufenden Asche erreicht werden kann und zum anderen die Bereitstellung einer weiteren Schlackenabtropfkante, die für einen optimalen Schlackeablauf sorgt.The object of the invention is to provide a solution with which on the one hand a striation of the running ash can be achieved and on the other hand, the provision of another Schlackenabtropfkante, which ensures an optimal slag process.

Mit einem Vergasungsreaktor der eingangs bezeichneten Art wird diese Aufgabe gemäß der Erfindung dadurch gelöst, dass die die Schotten tragende Wand unterhalb der Schotten über einen Absatz mit gewellter Oberfläche in eine im Durchmesser verringerte Zylinderwand übergeht.With a gasification reactor of the type described, this object is achieved according to the invention in that the bulkhead carrying the wall passes below the bulkheads via a shoulder with a wavy surface in a reduced diameter cylinder wall.

Durch die gewellte Oberfläche und Tiefpunkte unterhalb der Schotten wird erreicht, dass die Schlacke gezielt in Strähnen aus den Wellentälern ablaufen kann und damit kein geschlossener Schlackefilm gebildet wird.Due to the undulating surface and the low points below the bulkheads, it is achieved that the slag can run off in targeted strands from the troughs and thus no closed slag film is formed.

Zusätzlich ist vorgesehen, dass die im Durchmesser verringerte Zylinderwand von einer im Durchmesser vergrößerten weiteren zylindrischen Wand umgeben ist, die in Schwerkraftrichtung an ihrem Ende eine zweite Schlackeabtropfkante bildet, wobei insbesondere vorgesehen ist, dass die weitere zylindrische Wand in ihrer vertikalen Position bezogen auf die erste Abtropfkante verstellbar angeordnet ist.In addition, it is provided that the reduced diameter in the cylinder wall of an enlarged diameter in another surrounded cylindrical wall which forms in the direction of gravity at its end a second Schlackeabtropfkante, wherein it is provided in particular that the further cylindrical wall is arranged adjustable in its vertical position relative to the first drip edge.

Ist hier von "Verstellbarkeit" die Rede, so betrifft diese eine optimale Einstellung gegenüber der Abtropfkante nach den gegebenen und betriebsbedingten Vorgaben. Nach Optimierung bedarf es einer weiteren Verstellbarkeit nicht, insbesondere nicht während des Betriebes des Reaktors.If the term "adjustability" is mentioned here, this refers to an optimum setting with respect to the drip edge according to the given and operational requirements. After optimization, there is no need for further adjustability, especially not during operation of the reactor.

Die Erfindung sieht auch vor, dass die zylindrische zweite Abtropfkante von einer im Durchmesser vergrößerten weiteren zylindrischen Wand umgeben ist, die wenigstens einen Teil eines Gasübergangsbereiches umschließt. In der Praxis begrenzt diese äußere zylindrische Wand den Übergangsbereich in den Quenchraum bzw. Quenchkanal.The invention also provides that the cylindrical second drip edge is surrounded by a diameter wall which is enlarged in diameter and which encloses at least part of a gas transition region. In practice, this outer cylindrical wall limits the transition region into the quench chamber or quench channel.

Die Erfindung sieht darüber hinaus auch vor, dass wenigstens ein Schott der Wirbelbremse mit einer Einrichtung zur Wärmestromdichte-Messung ausgerüstet ist.In addition, the invention also provides that at least one bulkhead of the fluidized-bed brake is equipped with a device for measuring the heat flux density.

In einer möglichen Ausgestaltung sieht die Erfindung auch vor, dass die zweite zylindrische Wand und die weitere zylindrische Wand mit einer glatten, ebenen, korrosionsbeständigen Oberfläche versehen sind, z.B. durch Verwendung von plattierten Super-Ω-Rohren, wobei die drallvermindernden Schotten, die wellenförmige Übergangsfläche und die die erste Abtropfkante bereitstellende Zylinderwand als Standard-Rohr-Steg-Rohrwand mit Bestiftung und Bestampfung ausgebildet ist.In one possible embodiment, the invention also provides that the second cylindrical wall and the further cylindrical wall are provided with a smooth, flat, corrosion-resistant surface, e.g. by using plated Super-Ω-tubes, wherein the swirl-reducing bulkheads, the undulating transitional surface and the cylinder wall providing the first drip-edge are formed as a standard pipe-web pipe wall with potting and potting.

Der in Fig. 1 dargestellte, allgemein mit 1 bezeichnete Vergasungsreaktor weist einen Druckbehälter 2 auf, in dem von oben nach unten ein durch eine Membranwand 3 umschlossener Reaktionsraum 4 auf Abstand zum Druckbehälter 2 angeordnet ist. Die die Membranwand 3 beaufschlagende Kühlmittelzuleitung ist mit 5 bezeichnet. Dabei geht die Membranwand 3 über einen unteren Konus 6 in einen verengten Kanal als Teil eines mit 8 bezeichneten Übergangsbereiches über, wobei im verengten Übergangskanal 7 Drallbremsen 9 angedeutet sind. Mit 10a ist eine Abtropfkante im Übergangsbereich 8 für die flüssige Asche im Übergangsbereich im Abstand zur ersten Abtropfkante 10 am Ende des Übergangskanales 7 bezeichnet.The in Fig. 1 represented, generally designated 1 gasification reactor has a pressure vessel 2, in which from top to bottom, an enclosed by a membrane wall 3 reaction space 4 at a distance from the pressure vessel 2 is arranged. The membrane inlet 3 acting on the coolant supply line is denoted by 5. In this case, the membrane wall 3 passes via a lower cone 6 in a narrowed channel as part of a transition region designated 8, wherein in the narrowed transition channel 7 swirl brakes 9 are indicated. 10a, a drip edge in the transition region 8 for the liquid ash in the transition region at a distance from the first drip edge 10 at the end of the transition channel 7 is designated.

An den Übergangsbereich 8 schließt sich ein Quenchraum bzw. Quenchkanal 11, gefolgt von einem Schlackesammelbehälter 12 in einem Wasserbad 13 an.The transition region 8 is followed by a quench chamber or quench channel 11, followed by a slag collecting container 12 in a water bath 13.

Wie sich aus den Fig. 2 und 3 ergibt, geht die mit den die Drallbremse bildenden Schotten 9 ausgerüstete Wand 14 in einen Absatz 15 über, der eine gewellte Oberfläche aufweist, die in Fig. 3 angedeutet ist, wobei die einzelnen Wellen mit 16 bezeichnet sind. Hieran schließt sich wiederum eine glatte, im Durchmesser veränderte Zylinderwand 17 an, die eine erste Abtropfkante 18 bereitstellt.As is clear from the FIGS. 2 and 3 results, with the swirl brake forming bulkheads 9 equipped wall 14 is in a paragraph 15 on which has a corrugated surface, the in Fig. 3 is indicated, wherein the individual waves are denoted by 16. This is followed by a smooth, in the Diameter changed cylinder wall 17, which provides a first drip edge 18.

Der Übergangskanal 7 einschließlich der zur Strähnenbildung der Schlacke herangezogenen Gestaltungen des Übergangsbereiches zwischen der Wand 19 und der Wand 18 ist von einer weiteren, zylindrischen Wand umgeben, die über eine in Fig. 2 schräg dargestellte Wandscheibe 20 mit der den Übergangsraum 8 umschließenden zylindrischen Wand 21 gasdicht in Verbindung steht.The transition duct 7, including the designs of the transitional area between the wall 19 and the wall 18, which are used to form a layer of slag, is surrounded by a further, cylindrical wall, which has an in-wall Fig. 2 obliquely shown wall plate 20 with the transitional space 8 enclosing the cylindrical wall 21 is gas-tight in communication.

Die Besonderheit liegt zum einen darin, dass die den Übergangskanal 7 umschließende zylindrische Wand 19 die weitere, mit 10 bezeichnete zweite Abtropfkante bereitstellt. Auch ist erfindungsgemäß das System aus zylindrischer Wand 19 und Wandscheibe 20 in der Höhe ein- bzw. verstellbar, was mit einem Doppelpfeil 22 angedeutet ist. Die eine derartige Einstellbarkeit ermöglichenden Dichtbereiche bzw. Übergangsbereiche der entsprechenden, mit Kühlmittel durchflossenen Rohre sind in Fig. 2 lediglich prinzipiell angedeutet und mit 23 und 24 bezeichnet.The peculiarity is, on the one hand, that the cylindrical wall 19 enclosing the transition channel 7 provides the further, second drip edge designated by 10. Also, according to the invention, the system of cylindrical wall 19 and wall plate 20 in height or adjustable, which is indicated by a double arrow 22. The such a adjustability enabling sealing areas or transition areas of the corresponding, with coolant flowed through pipes are in Fig. 2 merely indicated in principle and denoted by 23 and 24.

In Fig. 2 ist lediglich symbolisch angedeutet, dass wenigstens ein Schott 9 der Wirbelbremse mit einer Einrichtung 25 zur Wärmestrommessung ausgerüstet sein kann.In Fig. 2 is merely symbolically indicated that at least one bulkhead 9 of the fluidized brake can be equipped with a device 25 for heat flow measurement.

Natürlich ist das beschriebene Ausführungsbeispiel der Erfindung noch in vielfacher Hinsicht abzuändern, ohne den Grundgedanken zu verlassen. So können die in Abwinkelung gemäß Fig. 3 dargestellten Wellen 16 im entsprechenden Wandabsatz eckig oder gekrümmt ausgebildet sein, je nach Einsatz kann die Verrohrung der entsprechenden Wandbereiche unterschiedlich sein u. dgl. mehr.Of course, the described embodiment of the invention is still to be modified in many ways, without departing from the spirit. So in accordance with Fig. 3 Shafts 16 shown in the corresponding wall paragraph be angular or curved, depending on the application, the piping of the corresponding wall areas may be different u. like. More.
