Verfahren und Anlage zur Gewinnung von Generatorgas Process and system for the production of generator gas
aus vorwiegend aufbereiteten, nicht fossilen Abfallprodukten Die Erfindung bezieht sich auf ein Verfahren zur Gewinnung von Generatorgas aus vorwiegend aufbereiteten, nicht fossilen Abfallprodukten in einem Gasreaktor nach dem anlagengomäßen Grundaufbau und dem Verfahrensprinzip des .aup'patents.................. from predominantly processed, non-fossil waste products The invention relates to a method for the production of generator gas from predominantly processed, non-fossil waste products in a gas reactor according to the plant-standard Basic structure and the procedural principle of the .aup'patent ..................
( Patentanmeldung P 32 20 156.5 ).(Patent application P 32 20 156.5).
Dieses Hauptpatent, dessen vornehmliche Aufgabe insbesondere darin bestehen soll, aus sehr nassem Ausganosmaterial wie beispielsweise Baumrinde o.ä. Sägewerksabfällen,Gas zu erzeugen, macht deshalb auch von dem an sich bekannten Prinzip der aufsteigenden Vergasung Gebrauch, deren besondere Vorteile neben einem vollständigen Ausbrand und einer entsprechend guten Umsetzung des Brennstoffes in Gase, insbesondere noch die Möglichkeit der Verwendung von Brennmsterialien mit relativ höherem Feuchtigkeitsgehalt ist, weil diese Feuchtigkeit durch die aufsteigenden Rohgas bereits weitestgehend ausgetrieben bzw.This main patent, its primary task in particular should consist of very wet organic material such as tree bark or the like. Sawmill waste to generate gas therefore also makes use of what is known per se Principle of ascending gasification use, its particular advantages besides one complete burnout and a correspondingly good conversion of the fuel in Gases, especially the possibility of using fuel with relatively higher moisture content is because this moisture is due to the rising Raw gas already largely expelled or
bei separater Vertrocknung fast restlos in ein und demselben Reaktor beseitigt werden kann.with separate drying almost completely in one and the same reactor can be eliminated.
Fallen nun in beispielsweise kommunal betriebenen Verbrennungs-bzw. Gaserzeugungs- oder Heizkraftwerksanlagen neben oder gemischt mit diesen fossilen Brennmaterialien auch Kunststoffahfälle, Altreifen u.dgl. in größeren Mengen an, so hat es sich gezeigt, daß das verfahrens- und anlagengemäße Grundprinzip nach dem Hauptpatent ....................... ( Patentanmeldung P 32 20 156.5 ) nicht ohne spezielle Modifikation übernommen werden kann, sondern weiterer, die darin enthaltene technische Lehre in sinnvoller Weise ergänzender, erfinderischer Schritte, sowohl auf der verfahrens- wie auch auf der anlagengemäßen Seite bedarf.Now fall in, for example, communally operated combustion or. Gas generation or combined heat and power plants alongside or mixed with these fossil fuels Fuel also plastic waste, old tires and the like in larger quantities, So it has been shown that the process and plant-related basic principle according to the main patent ....................... (patent application P 32 20 156.5) not can be adopted without any special modification, but rather more that is included contained technical teaching in a meaningful way complementary, inventive steps, both on the procedural and on the plant side.
Die Schaffung der hierfür geeigneten Maßnahmen und Vorrichtungen bzw. zusätzliche, die Grundanlage nach dem Hauptpatent ergänzende Schritte, die entweder nur die Gaserzeugung aus den weitestgehend nicht fossilen Abfallprodukten oder aber letzteren im Wechsel bzw. gemischt mit fossilen, ermöglichen, sind daher Aufgabe der vorliegenden Erfindung. Eine Teilaufgabe hierbei ist noch in dem Bestreben zu sehen, durch geeignete Verfahrensschritte auch aus Abfallprodukten minderer bzw. wenig umweltfreundlicher Art, bei deren Beseitigung eine relativ hohe Gaaqualität zu erzeugen.The creation of suitable measures and devices or additional steps that complement the basic system according to the main patent, either only the gas generation from the largely non-fossil waste products or else the latter, alternating or mixed with fossil fuels, are therefore a task of the present invention. A partial task here is still in the endeavor to see, through suitable process steps, also from waste products of lesser or not very environmentally friendly, with their disposal a relatively high quality Gaa to create.
Gelöst wird diese Aufgabe dabei in überraschend einfacher und überzeugender Weise durch die in den Patentansprüchen angegebenen Verfahrenaschritte sowie den zugehärigen, anlagemäßigen Aufbau. Erfindungswesentliches Kriterium ist dabei die Vorschaltung bzw. Zuordnung einer separaten, gasbeheizten Pyrolyseeinheit zu einem Schachtreektor nach dem Hauptpatent, die darin stattfindende Umwandlung der aufbereiteten, d.h. in eine Art Granulatform zerkleinerten Kunststoffabfälle, in Pyrolysekoks und die Aufgabe dieses Kokses in den Schacht reaktor.This task is solved in a surprisingly easier and more convincing way Way by the method steps specified in the claims and the associated, inherent structure. The essential criterion for the invention is Upstream or assignment of a separate, gas-heated pyrolysis unit to one Schachtreektor according to the main patent, the conversion of the processed, i.e. plastic waste shredded into a kind of granulate form, in pyrolysis coke and the task of this coke in the shaft reactor.
Auf diese Weise wird ein Verkleben, Verschmieren oder Verbacken des eigentlichen Reaktors durch die bei Hitzeeinwirkung zumeist schmelzenden Kunststoffe in vollem Umfang vermieden.This prevents the actual reactor due to the plastic, which usually melts when exposed to heat avoided in full.
In der Zeichnung ist nun ein Ausführungsbeispiel der erfindungsgemäßen.lösung als Prinzipschema dargestellt.The drawing now shows an embodiment of the solution according to the invention shown as a principle diagram.
Es zeigen: Fig. 1 eine zur Durchführung und Erläuterung des erfindungsgemäßen Verfahrens geeignete Anlage in Ansicht sowie teils im Längsschnitt und Fig. 2 einen Querschnitt durch das Pyrolyserohr gemäß der Linie A - 8.The figures show: FIG. 1 a for carrying out and explaining the inventive concept Process suitable system in view and partly in longitudinal section and FIG. 2 a Cross section through the pyrolysis tube according to line A-8.
Eine zur Durchführung der in den Patentansprüchen 1 und 2 angegebenen Verfahrensschritte erfindungsgemäß geeignete Anlage, zeichnet sich zunächst dadurch aus, daß dem Schachtreaktor 8 eine separate Pyrolyseeinheit 6, 6a, 8c zur Umwandlung der nicht fossilen Abfallmaterialien in Pyrolysekoks PK vorgeschaltet ist. In spezieller, baulicher Ausgestaltung kann dabei beispielsweise vorgesehen sein, daß die Pyrolyseeinheit 6, 6a, 6c aus einem länglichen, rohrförmigen Kanal 5 vorzugsweise rechteckigen bzw. quadratischen Querschnitts ( Fig. 2 ) besteht, eine Doppelwendung zur Bildung eines Heizgasringraumes Sa sowie den Rohrquerschnitt in Längsrichtung L durchsetzende Heizgastaschen 8c aufweist sowie über einen kopfseitigen Austragskanal 6b in den oberen Aufgabenbereich des Reaktorschachtes 8 einmündet.One for the implementation of the specified in claims 1 and 2 Process steps suitable according to the invention is initially characterized by this from that the shaft reactor 8 has a separate pyrolysis unit 6, 6a, 8c for conversion upstream of the non-fossil waste materials in pyrolysis coke PK. In special, structural design can be provided, for example, that the pyrolysis unit 6, 6a, 6c from an elongated, tubular channel 5, preferably rectangular or square cross-section (Fig. 2), a double turn to form a Heating gas annulus Sa and the pipe cross-section in Longitudinal direction L extending through heating gas pockets 8c and a head-side discharge channel 6b opens into the upper task area of the reactor shaft 8.
Zur Erzielung einer weitestgehend selbsttätigen, mechanisierten Arbeitsweise dieser Anlage sollte weiterhin noch vorgesehen sein, daß der Pyrolyseeinheit 6, 6a, 6b, 8c eine aus Abfallaufgabevorrichtung 1, Zerkleinerungseinheit 2, Zwischenbunker 3 mit Bandaustrag 4 und mechanischem Zuführsystem 7, 7a bestehende Abfallaufbereitungsanlage vorgeschaltet sowie das absatzweise arbeitende Zuführsystem 7, 7a über einen gasdicht geschlossenen Forderkanal 10a mit dem Pyrolyserohr 6 verbunden ist.To achieve a largely automatic, mechanized way of working this system should also be provided that the pyrolysis unit 6, 6a, 6b, 8c one of waste feeder 1, shredding unit 2, intermediate bunker 3 with belt discharge 4 and mechanical feed system 7, 7a existing waste processing plant upstream as well as the intermittent feeding system 7, 7a via a gas-tight closed conveying channel 10a is connected to the pyrolysis pipe 6.
Zusätzlich erforderlich ist ebenfalls noch je ein mechanisch betätigtes, gasdichtes Schieber- bzw. Schleusensystem 5a, 5b zwischen Aufgabetrichter 5 und Abfallaufnahmekammer 10 einerseits, sowie letzterer 10 und dem Förderkanal 1Ca andererseits; damit ein Austreten der umweltschädlichen Pyrolysegase aus dem Aufgabetrichter 5 vermieden wird, werden diese Schiebersysteme 5a und 5b im gegenseitigen Wechsel geöffnet oder geschlossen, je nachdem, ob gerade Granulat aus dem Bunker 3 über das Band 4 abgezogen und aufgegeben, oder aber mittels des Kolbens 7a das in der Kammer 10 liegende Material durch den Schacht 10a zum Pyrolyserohr 6, 6a vorgeschoben werden soll. Um die zerkleinerten Abfallprodukte ohne nennenswerten Widerstand in das Pyrolyeerohr einschieben zu kdnnen, ist schließlich noch vorgesehen, daß die Heizgastaschen kopf- sowie fußseitig geschlossen sind und in ihrem unteren, dem Förderkanal 10a benachbarten Bereich spitz zulaufen.A mechanically operated, gas-tight slide or lock system 5a, 5b between feed hopper 5 and Waste receiving chamber 10 on the one hand, as well as the latter 10 and the conveying channel 1Ca on the other hand; so that the environmentally harmful pyrolysis gases escape from the feed hopper 5 is avoided, these slide systems 5a and 5b alternate open or closed, depending on whether granules from the bunker 3 are over the tape 4 withdrawn and abandoned, or by means of the piston 7a in the Chamber 10 lying material through the shaft 10a to the pyrolysis pipe 6, 6a is to be advanced. To get the shredded waste products without significant Finally, there is also provision for inserting resistance into the pyrolytic tube, that the gas pockets are closed at the top and bottom and in their lower, the area adjacent to the conveying channel 10a taper to a point.
In gleichem Maße, wie nun also durch das zuvorbeschriebene, absatzweise arbeitende FErdersystem die zerkleinertan Abfallstoffe in das Pyrolyserohr 6, 6a eingeschoben werden, wird fertiger Pyrolysekoks PK in den Schachtreaktor 8 ausgestoßen. Zugleich entweichen auch die Pyrolysegase PG in den Reaktor und erfahren dort eine Art Nachverbrennung sowie Aufbereitung in reines Generatorgas hoher Qualität. Bezüglich der Arbeitsweise des Reaktors 8 selbst, wird auf die detaillierte Beschreibung des Hauptpatents ...............To the same extent, as now by the previously described, paragraph by paragraph working conveyor system, the crushed waste materials in the pyrolysis tube 6, 6a are inserted, finished pyrolysis coke PK is ejected into the shaft reactor 8. At the same time, the pyrolysis gases PG escape into the reactor and experience a there Type of afterburning as well as processing in pure generator gas of high quality. In terms of the operation of the reactor 8 itself, is referred to the detailed description of the Main patent ...............
