Abstract

The gasification of solid fuels is influenced with a view to a better gas yield within a shorter time by alternate blowing and de-ashing of a fuel bed. For carrying out the process, a novel conical rotary grid structure is disclosed, whose aperture angle corresponds to the angle of repose of the loose material, so that the layer thickness of the loose material which lies above and is to be gasified is evened out. This design also allows the flow through the bed of loose material to be evened out. The grid has alternating blowing and de-ashing slots. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zum Betrieb eines Vergasers mit drehbarem Rost oder Boden für feste Brennstoffe, bei dem die Brennstoffe von einer Vorwärmezone über eine Vergasungszone einer Aschenabkühlung mit Aschenabtrennung zugeführt werden und ein gasförmiges Vergasungsmedium im Gegenstrom zur Bewegung des Brennstoffes in die Vergasungszone eingebracht wird und einen Reaktor zur Durchführung des Verfahrens.The invention relates to a method for operating a gasifier with a rotatable grate or bottom for solid fuels, in which the fuels are fed from a preheating zone via a gasification zone to an ash cooling system with ash separation and a gaseous gasification medium is introduced into the gasification zone in countercurrent to the movement of the fuel and a reactor to carry out the process.

Es ist bekannt (AT-PS 68.876, DE-PS 656.988) Feststoffvergaser mit Drehrost im Gegenstrom mit einem Vergasungsmedium kontinuierlich zu betreiben. Hiebei hat es sich herausgestellt, daß das Vergasungsmedium bevorzugte Pfade durch das Feststoffbett nimmt, wodurch der Ausbrand bzw. die Vergasung ungleichmäßig erfolgt. Darüber hinaus kommt es zum örtlichen Aufschmelzen der Schlacke und damit zur Klumpenbildung und letzten Endes zu Unregelmäßigkeiten im Schlackengang.It is known (AT-PS 68.876, DE-PS 656.988) to operate solid gasifier with rotating grate in countercurrent with a gasification medium continuously. Hiebei it has been found that the gasification medium takes preferred paths through the solid bed, whereby the burnout or gasification takes place unevenly. In addition, there is local melting of the slag and thus the formation of lumps and ultimately irregularities in the slag passage.

Um diesen Nachteilen zu begegnen, wurde durch Erhöhung der Temperatur die Schlacke verflüssigt und dieselbe im Schlackenauslaß granuliert. Dies führt zu einem Wärmeverlust, einem feuchten Aschenaustrag und zu einer Begrenzung der Art des zu vergasenden Brennstoffes, so daß bei Verwendung von Müll infolge der wechselnden Zusammensetzung des Mülls mit Schwierigkeiten im Aschenaustrag zu rechnen ist.In order to counter these disadvantages, the slag was liquefied by increasing the temperature and the same was granulated in the slag outlet. This leads to a loss of heat, a moist ash discharge and to a limitation of the type of fuel to be gasified, so that when using waste, difficulties in ash discharge are to be expected due to the changing composition of the waste.

Die Erfindung hat es sich zur Aufgabe gestellt, den bekannten Nachteilen zu begegnen und einen Trockenaschenaustrag in Staubform zu ermöglichen. Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, daß das Vergasungsmedium im Bereich der Aschenabkühlungszone kontinuierlich über eine mit gleicher Drehzahl kreisende Aufgabestelle dem Feststoffbett zugeführt wird und das Festoffbett, insbesondere im Bereich der Aschenzone, abschnittweise dadurch abwechselnd durchblasen und absetzen gelassen wird bzw. das einzelne Korn des Feststoffbettes diskontinuierlich vom Vergasungsmedium umströmt wird und daß die Entaschung des Vergasers zonenweise in der Zeit der jeweiligen Nichteinblasung des Vergasungsmediums erfolgt. Weitere Verfahrensmerkmale sind in den Unteransprüchen 2 und 3 angegeben. Der erfindungsgemäße Reaktor zur Durchführung des Verfahrens ist dadurch gekennzeichnet, daß der Reaktor einen drehbaren Rost oder Boden mit reihenförmig angeordneten Öffnungen und/oder Schlitzen aufweist, von welchen je zweite Reihe überdacht ist.The object of the invention is to overcome the known disadvantages and to enable dry ash discharge in dust form. The process according to the invention is characterized in that the gasification medium in the area of the ash cooling zone is continuously fed to the solid bed via a feed point rotating at the same speed and the solid bed, in particular in the area of the ash zone, is alternately blown through and settled in sections or the individual grain of the Solidification bed is discontinuously flowed around by the gasification medium and that the gasification of the gasifier takes place zone by zone in the time of the respective non-injection of the gasification medium. Further procedural features are specified in subclaims 2 and 3. The reactor according to the invention for carrying out the process is characterized in that the reactor has a rotatable grate or base with openings and / or slots arranged in rows, of which the second row is covered.

Die Erfindung ist in den angeschlossenen Fig. 1 bis 4 beispielsweise und schematisch dargestellt.

  • Fig. 1 zeigt einen Aufriß durch einen erfindungsgemäßen Reaktor,
  • Fig. 2 eine Draufsicht gemäß Schnittlinie II in Fig. 1,und die
  • Fig. 3 und 4 zeigen Details gemäß der Schnittlinie III bzw. IV in Fig. 2.
The invention is shown for example and schematically in the connected FIGS. 1 to 4.
  • 1 shows an elevation through a reactor according to the invention,
  • Fig. 2 is a plan view according to section line II in Fig. 1, and
  • 3 and 4 show details along the section line III and IV in Fig. 2nd

In Fig. 1 ist ein Reaktor (1), der mit einem zu vergasenden Brennstoff gefüllt ist, dargestellt. Der drehbare Boden (2) oder Rost des Vergasers ist kegelförmig ausgebildet und weist Schlitze (4) auf, durch welche das Vergasungsmedium (5) in das Brennstoffbett aufgegeben wird. Da der Boden gemäß Pfeil (9) rotiert, werden durch das Vergasungsmedium immer andere Brennstoffpartikel angeblasen, wodurch es zu einer abwechselnden Durchblasung und ungestörten Entgasung kommt. Die Asche gast möglichst vollständig aus, wird nicht überhitzt und führt daher nicht zum Zusammenklumpen. Zur Erreichung dieses Zwecks erfolgt die Drehung des Bodens (2) oder Rostes mit konstanter Drehzahl oder eventuell intermittierend. Der Aschengehalt im Brennstoffbett nimmt von oben nach unten zu und erreicht im Bodenbereich praktisch 100 %. Zur Entaschung sind im Boden (2) Schlitze (3) vorgesehen, die mit dem Boden (2) kreisen und die teilweise von einem keilförmigen Abdeckblech überdeckt sind, so daß die Asche (6) beim Verlassen des Abdeckbleches am Endes des Keiles in den sich drehenden Schlitz (3) fällt und durch diesen zu einem feststehenden Rutschensystem (10) geleitet und ausgetragen wird.1 shows a reactor (1) which is filled with a fuel to be gasified. The rotatable base (2) or grate of the carburetor is conical and has slots (4) through which the gasification medium (5) is fed into the fuel bed. Since the bottom rotates according to arrow (9), other fuel particles are always blown through the gasification medium, which leads to an alternating blowing and undisturbed degassing. The ash fumes out as completely as possible, is not overheated and therefore does not cause it to clump together. To achieve this purpose, the bottom (2) or grate is rotated at a constant speed or possibly intermittently. The ash content in the fuel bed increases from top to bottom and practically reaches 100% in the floor area. For ash removal, slots (3) are provided in the bottom (2) which circle with the bottom (2) and which are partially covered by a wedge-shaped cover plate, so that the ashes (6) leave the cover plate at the end of the wedge rotating slot (3) falls and through this to a fixed slide system (10) and discharged.

In den Reaktor wird durch die Einfüllöffnung (11) gemäß dem Pfeil (12) frischer Brennstoff zugeführt, dessen Lage durch den Schüttwinkel im Vergaser begrenzt wird. Oberhalb des Schüttkegels bildet sich ein freier Raum,in dem sich das erzeugte Gas sammelt und schließlich über den Stutzen (13) gemäß Pfeil (14) abgeführt wird. Wenn der Schüttwinkel des zu vergasenden Brennstoffes mit dem Öffnungswinkel des kegelförmigesn Rostes größenordnungsmäßig übereinstimmt, ist die Schüttguthöhe des Brennstoffes über dem Rost an allen Stellen praktisch gleich hoch, so daß auch der Durchströmungswiderstand und damit die Durchströmung etwa gleich ist, wodurch Gassenbildungen vermeidbar sind.Fresh fuel is fed into the reactor through the filler opening (11) according to the arrow (12), the position of which is limited by the angle of repose in the gasifier. A free space forms above the pouring cone, in which the generated gas collects and is finally discharged via the nozzle (13) according to arrow (14). If the angle of repose of the fuel to be gasified coincides with the opening angle of the conical grate in the order of magnitude, the bulk height of the fuel above the grate is practically the same at all points, so that the flow resistance and thus the flow is approximately the same, which avoids the formation of alleys.

In Fig. 2 ist ein Schnitt gemäß Schnittlinie II in Fig. 1 dargestellt. Der Schnitt zeigt den drehbaren Boden (2) oder Rost in Draufsicht,und man erkennt zwei unterschiedliche Arten von evolventenförmigen Abdeckungen und Schlitzen, die die Zuführungsschlitze (4) für das Vergasungsmedium bzw. die Entaschungsöffnungen oder Schlitze (3) für die Asche (6) darstellen. Die Evolventen sind dabei in Drehrichtung des Bodens (2) nach rückwärts gekrümmt. Zur Vereinfachung der Darstellung ist jeweils nur eine schlitzförmige Öffnung zur Entaschung und zur Begasung dargestellt. Die Drehrichtung des Bodens (2) ist gemäß Pfeil (9) so gewählt, daß die keilförmig in Drehrichtung angeordneten, dachartigen Abdeckbleche (8) beim Drehen des Bodens (2) das Schüttgut etwas anheben, so daß das Vergasungsmedium gemäß Fig. 3 leichter in das Brennstoffbett eingebracht werden kann und bei der Entaschung (Fig. 4) die sich sammelnde Asche vom Abdeckblech (8) direkt in den Schlitz (3) fällt. Um einen seitlichen Durchtritt des Gases in das Brennstoffbett zu ermöglichen, ist das Abdeckblech (8) in Fig. 3 zum Schutz der Öffnung (4) überlappend zur Öffnung (4) vorgesehen, während in Fig. 4 das Abdeckblech (8) kleiner als die Öffnung ist, so daß das herabfallende Aschenteilchen durch den Schlitz (3) über das Rutschensystem (10) abgeführt werden kann. Die ständige abwechselnd erfolgende Verdichtung und Auflockerung der Asche im Bodenbereich ist sowohl dem Aschenaustrag als auch der Ausgasung sowie dem Gaseintrag zweckdienlich.2 shows a section along section line II in FIG. 1. The section shows the rotatable bottom (2) or grate in plan view, and two different types of involute-shaped covers and slots can be seen, the feed slots (4) for the gasification medium or the deashing openings or slots (3) represent for the ashes (6). The involutes are curved backwards in the direction of rotation of the base (2). To simplify the illustration, only one slit-shaped opening for ash removal and fumigation is shown. The direction of rotation of the base (2) is selected according to arrow (9) so that the roof-like cover plates (8) arranged in a wedge shape in the direction of rotation raise the bulk material slightly when the base (2) is turned, so that the gasification medium according to FIG the fuel bed can be inserted and during the ash removal (Fig. 4) the accumulating ash from the cover plate (8) falls directly into the slot (3). In order to allow the gas to pass laterally into the fuel bed, the cover plate (8) in FIG. 3 is provided to protect the opening (4) overlapping the opening (4), while in FIG. 4 the cover plate (8) is smaller than that Opening is so that the falling ash particles can be discharged through the slot (3) over the slide system (10). The constant alternating compression and loosening of the ash in the floor area is useful for ash removal as well as outgassing and gas input.
