Die Erfindung betrifft eine Pyrolyseanlage für die Vergasung einer Vergasungsmasse, wie Biomasse und energetische Reststoffe mit einem elektrisch beheizten Pyrolysereaktor, in dem mehrere mit Fördervorrichtungen ausgestattete Führungsrohre horizontal oder mit geringer Neigung angeordnet sind, wobei zum Beschicken eines Eingangsführungsrohres mit der Vergasungsmasse eine Aufgabeeinrichtung vorgesehen ist und am Austragende des Ausgangsführungsrohres ein Gasauslass zum Ableiten des Pyrolysegases und eine Fördervorrichtung für den Austrag der entgasten Rückstandsmasse angeordnet sind.The invention relates to a pyrolysis system for the gasification of a gasification mass, such as biomass and energetic residues with an electrically heated pyrolysis reactor, in which a plurality of guide tubes equipped with conveying devices are arranged horizontally or with a slight inclination, a feed device being provided for charging an input guide tube with the gasification mass and a gas outlet for discharging the pyrolysis gas and a conveying device for the discharge of the degassed residue mass are arranged at the discharge end of the outlet guide tube.
Eine derartige Pyrolyseanlage ist durch das Gebrauchsmuster
Herkömmliche Vergaseranlagen für Biomasse, wie Holz, sind in vielfältigen Ausführungsarten seit langer Zeit bekannt. Diese Holzvergaseranlagen arbeiten mit reduzierter Luftzufuhr, wobei ein Teil der zu vergasenden Biomasse verbrannt wird, um die zur Vergasung notwendige Hitze zu erzeugen.Conventional gasification systems for biomass, such as wood, have long been known in a variety of designs. These wood gasification plants work with reduced air supply, whereby part of the biomass to be gasified is burned in order to generate the heat necessary for gasification.
Aus der
Die bekannt gewordenen Pyrolyseanlagen haben alle den Nachteil, dass durch Luftzutritt die Vergasungsparameter ungünstig sind, sodass es in erhöhtem Maß zu Teerbildungen kommt und überdies die Verteilung der Prozesswärme unstabil wird.The pyrolysis plants that have become known all have the disadvantage that the gasification parameters are unfavorable due to the entry of air, so that tar formation occurs to an increased extent and, moreover, the distribution of the process heat becomes unstable.
Aufgabe der vorliegenden Erfindung ist es, alle Nachteile des Standes der Technik zu beseitigen und eine Pyrolyseanlage vorzusehen, die eine volle Wärmeausnützung gewährleistet und sicherstellt, dass die benötigte Pyrolysetemperatur und die notwendige Verweilzeit in den Führungsrohren erzielt wird. Die Bildung von Teeren und Schadstoffen soll weitgehend vermieden werden, um nachfolgende Reinigungsschritte nicht zu erschweren.The object of the present invention is to eliminate all the disadvantages of the prior art and to provide a pyrolysis system which ensures full heat utilization and ensures that the required pyrolysis temperature and the necessary dwell time in the guide tubes are achieved. The formation of tars and pollutants should be largely avoided so as not to complicate subsequent cleaning steps.
Die vorliegende Erfindung ist dadurch gekennzeichnet, dass zumindest zwei, bevorzugt drei, Führungsrohre mit je einer Fördervorrichtung übereinanderliegend angeordnet und über Verbindungsschächte verbunden sind, dass die Führungsrohre individuell beheizbar sind, dass die Aufgabeeinrichtung eine den Zutritt von Zuluft verringernde oder gänzlich verhindernde Luftschleuse aufweist und dass der Pyrolysereaktor von einem hitzedämmenden und allseitig den Zustrom von Fremdluft verhindernden Mantel umgeben ist, wobei das hitzedämmende Material den Pyrolysereaktor vollständig umschließt, und wobei der Mantel eine luftdichte Außenhaut aufweist, die den Pyrolysereaktor allseitig umschließt, und die Einleitungsrohre und Durchbrüche für die Fördervorrichtungen so dicht angeordnet sind, dass Zuluft verhindert ist.The present invention is characterized in that at least two, preferably three, guide tubes, each with a conveying device, are arranged one above the other and connected via connecting shafts, that the guide tubes can be heated individually, that the feed device has an air lock that reduces or completely prevents the entry of supply air, and that the pyrolysis reactor is surrounded by a heat-insulating jacket which prevents the inflow of external air on all sides, the heat-insulating material completely enclosing the pyrolysis reactor, and the jacket having an airtight outer skin which surrounds the pyrolysis reactor on all sides, and the inlet pipes and openings for the conveying devices so tight are arranged that supply air is prevented.

Die
Die Pyrolyseanlage 1 umfasst im Wesentlichen den elektrisch beheizten Pyrolysereaktor 2, den Gasreiniger 3, den Wärmetauscher 4 und den Gaswäscher 5. Weiters ist ein Lager 6 vorgesehen, von dem die Vergasungsmasse durch einen Horizontal- und Schrägförderer 7 einer Aufgabeeinrichtung 8 des Pyrolysereaktors zugeführt werden kann. Im Gasreiniger kommt es zu einer Trennung des Pyrolysegas von Staub, wobei der sich absetzende Staub über die Austragvorrichtung 9 aus dem System entfernt wird. Das gereinigte Rohgas gelangt über die Rohgasleitung 10 in den Wärmetauscher 4 in welchem das Rohgas in zumindest zwei Stufen auf etwa 30° abgekühlt wird. Im vorliegenden Ausführungsbeispiel wird das dabei entstehende abgekühlte Gas noch einem Gaswäscher 5 zugeleitet, von welchem das Reingas über die Reingasleitung 11 dem Blockheizkraftwerk 12 zur Erzeugung elektrischer und eventuell auch thermischer Energie zugeleitet wird. Die Steuerung der Anlage erfolgt von dem Steuerungs- und Bürogebäude 13.The
Es versteht sich von selbst, dass der Aufbau dieser Anlage nur exemplarisch und beispielsweise gilt. Anstatt der Zuleitung zu einem Blockheizkraftwerk kann auch die Einspeisung in ein Heizgasnetzwerk oder einen anderen Gasverbraucher erfolgen. Die Zufuhr der Vergasungsmasse und der Abtransport der festen Rückstände kann selbstverständlich auch auf andere Weise erfolgen.It goes without saying that the construction of this system applies only as an example and for example. Instead of being fed to a combined heat and power plant, it can also be fed into a heating gas network or another gas consumer. Of course, the supply of the gasification mass and the removal of the solid residues can also take place in another way.
In
Der erste Wärmetauscher 15, durch den eine Abkühlung des Pyrolysegases auf etwa 100°C erfolgt, ist der Ausgangspunkt für eine Kondensatleitung 16, die das Kondensat in den Einleitungspunkt 17 am Ausgangsende des Pyrolysereaktors rückführt, wodurch das Kondensat einer Temperatur von 700 bis 800°C ausgesetzt und thermisch verändert (reformiert) wird.The
Die
Die Beheizung des Pyrolysereaktors 2 erfolgt über elektrische Heizelemente 25, die die Führungsrohre gemäß der gewünschten Temperaturführung beheizen. Die in den einzelnen Rohren erzeugten Temperaturen liegen beispielsweise bei 750 bis 800°C im Eingangsführungsrohr, bei 800 bis 850°C im Zwischenführungsrohr und bei 850 bis 900°C und bis zu 1200°C im Ausgangsführungsrohr. Die Temperaturen können an die jeweils zu behandelnde Vergasungsmasse angepasst werden. Falls beispielsweise die Entstehung von Dioxin zu befürchten ist, kann die Temperatur im Eingangsführungsrohr entsprechend angehoben werden.The
Zufolge der für die Pyrolyse erforderlichen hohen Temperatur im Pyrolysereaktor ist es notwendig, den Pyrolysereaktor besonders wärmebeständig und -dämmend aufzubauen, wobei bei Konstruktionen gemäß Stand der Technik das Problem auftrat, das Eindringen von Luft zu verhindern.As a result of the high temperature required for the pyrolysis in the pyrolysis reactor, it is necessary to construct the pyrolysis reactor in a particularly heat-resistant and insulating manner, with the problem of preventing the penetration of air in constructions according to the prior art.
Gemäß vorliegender Erfindung weist der Pyrolysereaktor einen Baukörper auf, der aus hitzedämmendem Material besteht. Er umschließt den Pyrolysereaktor vollständig und wird bevorzugt aus Blöcken expandierten verdichteten Keramikvlieses hergestellt. Derartige Keramikblöcke sind bekannt. Sie werden in verdichtetem zusammengedrücktem Zustand eingesetzt und dann auf Ihre gewünschten Außenabmessungen entspannen gelassen. So entstehen etwa Quader mit den Maßen 300 x 300 x 300 mm , die fest aneinander liegen und hohe Wärmedämmung mit Dichtigkeit verbinden. Ein so ausgebildeter Mantel 51 ist jedoch in überraschender Weise als Baukörper noch immer nicht geeignet, um den Zutritt von Fremdluft zu verhindern. Gemäß Erfindung wird das Problem gelöst durch die Anordnung einer luftdichten Außenhaut 26, die den 300 x 300 mm allseitig umschließt, und auch die Einleitungsrohre und Durchbrüche für die Schneckentriebe sind so dicht angeordnet, dass Zuluft verhindert ist.According to the present invention, the pyrolysis reactor has a structure which consists of heat-insulating material. It completely surrounds the pyrolysis reactor and is preferably made from blocks of expanded, compressed ceramic fleece. Such ceramic blocks are known. They are used in a compressed, compressed state and then let relax to your desired external dimensions. This creates cuboids with dimensions of 300 x 300 x 300 mm, which lie firmly against each other and combine high thermal insulation with tightness. However, a
Für den Antrieb der Fördervorrichtungen 18 sind Elektroantriebe 27 vorgesehen. Der Förderantrieb 53, z.B. eine elektrisch betriebene Förderschnecke, entfernt den abgeschiedenen Staubanteil aus dem Gasreiniger 3 zur Austragvorrichtung 9.
Weitere Erläuterungen zum Aufbau des Pyrolysereaktors folgen anhand der
Die Aufgabevorrichtung 8 umfasst einen Falltrichter 28 zur Aufnahme der Vergasungsmasse, welches vom Lager 6 über den Horizontal- und Schrägförderer herangeführt wird. Zwei Schleusenschieber 29 bilden mit dem dazwischen angeordneten Schleusenrohr 30 eine Luftschleuse 50, um das Eindringen von Fremdluft weitgehend zu verhindern. Zusätzlich kann das Schleusenrohr 30 auch noch einen Anschluss an eine Vakuumpumpe erhalten, um die eingetragene Fremdluft weitergehend zu entfernen.The
Weiters gelangt die Vergasungsmasse durch den Fallschacht 31 entweder direkt in das Zufuhrrohr 32, um die Vergasungsmasse über die Fördervorrichtung 18 in das Eingangsführungsrohr 19 zu transportieren, oder, der Fallschacht 31 mündet in einen Verteiler 33, wie dargestellt, um die Masse auf mehrere nebeneinander angeordnete Zufuhrrohre aufzuteilen, wenn mehrere Führungsrohrgruppen vorgesehen sind.Furthermore, the gasification mass passes through the
Am anderen Ende des Pyrolysereaktors mündet das Austragende 24 des Ausgangsführungsrohres 23 in den ebenfalls luftdicht ausgestatteten Gasreiniger 3. In diesen Gasreiniger gelangt das Pyrolysegas mit den in ihm enthaltenen Fremdstoffen und Stäuben mit der Austragstemperatur von mehr als 850°C. Durch diese hohe Temperatur ist gewährleistet, dass die Reinigungsfilter 34, bei denen es sich in bevorzugter Weise um Keramikkerzen handelt, nicht durch etwa enthaltene Teere und Staub verlegt werden. Die Teerbildung wird durch die hohen Temperaturen verhindert. Die Fördervorrichtung trägt feste Rohstoffe aus dem Pyrolysereaktor hinaus.At the other end of the pyrolysis reactor, the
In der Gassammelkammer 35 sammelt sich das gereinigte Gas und wird über den Auslass 48 dem Gaswäscher 5 zugeführt. Über den Spülgaseinlass 36 wird gegebenenfalls intermittierend Reinigungsgas aus dem Drucktank 14 eingeblasen, um die Kerzen des Reinigungsfilters 34 von Zeit zu Zeit freizublasen. Bevorzugt werden zwei Reinigungsfiltergruppen parallel zueinander geschalten, sodass laufend zwischen Betriebszustand und Spülzustand gewechselt werden kann, ohne den Betrieb der Pyrolyseanlage unterbrechen zu müssen.The cleaned gas collects in the

Die thermische Dichtung des Bodens erfolgt mittels Isolierziegel 46, auf denen die hier nicht dargestellten Wände des Baukörpers aus Keramikvlies aufgebaut wird. Die diesbezüglichen quaderförmigen Isolationskörper sind in
Zu den Reinigungsfiltern 34 ist zu bemerken, dass sie bevorzugt Keramikkerzen sind, die einerseits den hohen Temperaturen standhalten können und die andererseits auch mit Stoffen kodiert werden können, um die Filterwirkung zu steuern. Beispielsweise kann das Keramikmaterial mit Nanopartikeln versetzt werden, um beispielsweise Stickstoff oder Schwefel oder Chlor aus dem Reingas zu entfernen. Es können auch kombinierte Universalkerzen vorgesehen werden, wenn über die Beschaffenheit der Vergasungsmasse keine genauen Kenntnisse vorliegen.With regard to the cleaning filters 34, it should be noted that they are preferably ceramic candles that can withstand the high temperatures on the one hand and that can also be encoded with substances on the other hand in order to control the filtering effect. For example, the ceramic material can be mixed with nanoparticles, for example to remove nitrogen or sulfur or chlorine from the clean gas. Combined universal candles can also be provided if there is no precise knowledge of the nature of the gasification mass.
Wichtig ist, dass die Filterkerzen trocken bleiben und keine Teerabscheidung erfolgt. Um sicherzustellen, dass die Filterkerzen schon von Anbeginn an betriebsbereit sind, wird die gesamte Anlage, also der dem Pyrolysereaktor und der Gasreiniger auf Betriebstemperatur gebracht, beispielsweise mittels Heizgebläsen, um von Anbeginn an die Teerabscheidung oder das Verstopfen der Filterporen zu verhindern.It is important that the filter candles remain dry and there is no tar separation. In order to ensure that the filter candles are ready for operation right from the start, the entire system, i.e. the pyrolysis reactor and the gas cleaner, is brought to operating temperature, for example by means of heating fans, to prevent tar separation or clogging of the filter pores from the start.
Die Zahl der übereinanderliegenden Führungsrohre einer Führungsrohrgruppe kann den Anforderungen angepasst werden. Beispielsweise können auch vier Führungsrohre übereinanderliegend vorgesehen sein. Der
Zum Gaswäscher 4 ist zu bemerken, dass dieser einen bekannten Aufbau haben kann. Ein erster Wärmetauscher 15 verringert die Gastemperatur auf etwa 100°C und im zweiten Wärmetauscher 52 erfolgt eine weitere Reduktion auf etwa 30°C. Mit dieser Temperatur kann das Gas dem Gaswäscher 5 zugeführt werden, der üblicherweise ein Ölwäscher ist oder andere Kohlenwasserstoffflüssigkeiten enthält, um letzte Reste von Stoffen, die in Kohlenwasserstoffen lösbar sind, aus dem Gas herauszuwaschen. Wie zuvor schon beschrieben wurde, kann aus dem ersten Wärmetauscher 15 etwa gebildetes Kondensat über die Kondensatleitung 16 der Pyrolyse rückgeführt werden.Regarding the
