Abstract

A conveyor for waste has a waste feed shaft which is laterally connected to a horizontally divided conveyor channel. A screw conveyor being drivable by a motor is located in the longitudinal direction of the conveyor channel. The conveyor channel opens into a housing, in particular into a pyrolysis reactor, which by way of example is operated in conjunction with a low-temperature carbonization combustion process. In order to easily eliminate blockages of the screw conveyor, a unit formed of the screw conveyor and the conveyor channel is disconnectably secured to the housing and is removable from the housing through the use of a traveling mounting. A method for inspecting the contents of a conveyor channel receiving waste and discharging into a housing, especially a pyrolysis reactor, includes disconnecting the conveyor channel from the housing, driving the conveyor channel away with a traveling mounting, and opening the conveyor channel.

Description

Die Erfindung bezieht sich auf eine Transporteinrichtung für Abfall, bei der ein Abfall-Zuführschacht an einen Transportkanal angeschlossen ist, in dessen Längsrichtung eine von einem Motor antreibbare Stopfschnecke angeordnet ist, und bei der der Transportkanal in ein Gehäuse, insbesondere in einen Pyrolysereaktor mündet. Die Transporteinrichtung wird zur thermischen Abfallentsorgung eingesetzt, insbesondere nach dem Schwelbrenn-Verfahren.The invention relates to a transport device for Waste, in which a waste feed shaft is connected to a transport channel is connected, in the longitudinal direction one of one Motor drivable stuffing screw is arranged, and at which the transport channel in a housing, in particular in a Pyrolysis reactor opens. The transport device becomes thermal waste disposal used, especially after the smoldering process.

Auf dem Gebiet der Abfallbeseitigung ist das sogenannte Schwelbrenn-Verfahren bekannt geworden. Das Verfahren und eine danach arbeitende Anlage zur thermischen Abfallentsorgung sind beispielsweise in der US-A-5 220 873, in der EP-A-0 302 310 sowie in der DE-A-38 30 153 beschrieben. Die Anlage zur thermischen Abfallentsorgung nach dem Schwelbrenn-Verfahren enthält als wesentliche Komponenten einen Pyrolysereaktor und eine Hochtemperatur-Brennkammer. Der Pyrolysereaktor setzt den über eine Abfall-Transporteinrichtung der eingangs genannten Art aufgegebenen Abfall in Schwelgas und Pyrolysereststoff um. Das Schwelgas und der Pyrolysereststoff werden sodann nach geeigneter Aufarbeitung dem Brenner der Hochtemperatur-Brennkammer zugeführt. Hier entsteht schmelzflüssige Schlacke, die über einen Abzug entnehmbar ist und die nach Abkühlung in verglaster Form vorliegt. Das entstehende Rauchgas wird über eine Rauchgasleitung einem Kamin als Auslaß zugeführt. In diese Rauchgasleitung sind insbesondere ein Abhitzedampferzeuger als Kühleinrichtung, eine Staubfilteranlage und eine Rauchgasreinigungsanlage eingebaut. Weiterhin befindet sich in der Rauchgasleitung ein Gasverdichter, der direkt am Ausgang der Rauchgasreinigungsanlage angeordnet und als Saugzuggebläse ausgebildet sein kann. Der eingebaute Gasverdichter dient zur Aufrechterhaltung eines - wenn auch nur geringen - Unterdrucks in der Pyrolysetrommel. Durch diesen Unterdruck wird verhindert, daß Schwelgas durch die Ringdichtungen der Pyrolysetrommel nach außen in die Umgebung austritt.In the field of waste disposal is the so-called Smoldering process became known. The procedure and one then working plant for thermal waste disposal are for example in US-A-5 220 873, in EP-A-0 302 310 and in DE-A-38 30 153. The plant for thermal waste disposal after the smoldering process contains as essential Components a pyrolysis reactor and a high temperature combustion chamber. The pyrolysis reactor uses a waste transport device of the type mentioned above Waste into carbonization gas and pyrolysis residue. The Smoldering gas and the pyrolysis residue are then made more suitable Refurbishing the burner of the high temperature combustion chamber fed. This creates molten slag that over a deduction is removable and the glazed after cooling Form is present. The resulting flue gas is fed through a Flue gas line fed to a chimney as an outlet. In these Flue gas pipes are in particular a heat recovery steam generator as a cooling device, a dust filter system and a flue gas cleaning system built-in. Furthermore is in the Flue gas pipe a gas compressor, which is located directly at the exit of the Flue gas cleaning system arranged and as a suction fan can be trained. The built-in gas compressor is used for Maintenance of a vacuum, even if only slight in the pyrolysis drum. Because of this negative pressure prevents carbonization gas through the ring seals of the pyrolysis drum leaks out into the environment.

Es hat sich gezeigt, daß bei einer Schwelbrenn-Anlage die Transporteinrichtung für Abfall blockiert oder gestört werden kann, wenn vom Abfall-Zuführschacht zu große Abfallpartikel in die Wendel der Schnecke hineinfallen. Eine schnelle Beseitigung einer Blockade der Stopfschnecke ist aber für einen Dauerbetrieb erforderlich, wird doch in der Regel kontinuierlich neuer Müll oder Abfall angeliefert. Von Bedeutung ist auch, daß die Stopfschnecke - sollte dies gegebenenfalls erforderlich sein - schnell ausgetauscht werden kann.It has been shown that in a smoldering plant Waste transport equipment blocked or disrupted may be too large waste particles from the waste feed chute fall into the helix of the snail. A quick fix a blockage of the stuffing screw is for one Continuous operation is required, as it is usually continuous new garbage or waste delivered. It matters also that the stuffing auger - should this be necessary if necessary be - can be exchanged quickly.

Aufgabe der Erfindung ist es demnach, eine Transporteinrichtung für Abfall der eingangs genannten Art derart auszubilden, daß eine Blockade rasch behoben werden kann. Weiterhin soll ein Verfahren zur Inspektion des Inhalts eines Transportkanals für Abfall, der in ein Gehäuse mündet, angegeben werden, das leicht und schnell durchführbar ist.The object of the invention is therefore a transport device to train for waste of the type mentioned at the beginning, that a blockage can be quickly removed. Farther is a method for inspecting the content of a transport channel for waste that flows into a housing that can be carried out easily and quickly.

Die Aufgabe bezüglich der Transporteinrichtung wird erfindungsgemäß dadurch gelöst, daß die Einheit aus Stopfschnecke und Transportkanal am Gehäuse lösbar befestigt, mittels einer Fahreinrichtung vom Gehäuse entfernbar ist und daß der Transportkanal (8) horizontal geteil ist.The task with regard to the transport device is according to the invention solved in that the unit from stuffing screw and transport channel releasably attached to the housing, by means of a driving device is removable from the housing and that the Transport channel (8) is divided horizontally.

Wird mittels dieser Fahreinrichtung die Einheit aus Stopfschnecke und Transportkanal vom Gehäuse, insbesondere einem Pyrolysereaktor, entfernt, so ist die Stopfschnecke leicht zugänglich, so daß dort eine Störung schnell behoben werden kann. Gegebenenfalls ist die Stopfschnecke auch leicht ausbaubar, so daß ein schneller Austausch gewährleistet ist. Dies ist insbesondere für Reparaturarbeiten an der Stopfschnecke oder für Wartungsarbeiten von Bedeutung.If this unit is used, the unit is made of a stuffing screw and transport channel from the housing, in particular one Pyrolysis reactor, so the stuffing screw is light accessible so that a malfunction can be remedied there quickly can. If necessary, the stuffing screw can also be easily removed, so that a quick exchange is guaranteed. This is particularly important for repair work on the stuffing screw or important for maintenance work.

Als Fahreinrichtung kann insbesondere eine Art Wagen oder eine Lafette dienen, die auf mindestens einer Schiene bewegbar ist. Die Bewegung kann dabei von Hand, bevorzugt aber maschinell durchgeführt werden.In particular, a type of wagon or a The carriage is movable on at least one rail is. The movement can be done manually, but preferably mechanically be performed.

Um eine besonders schnelle Beseitigung von Blockaden und/oder einen raschen Austausch der Stopfschnecke sicherzustellen, ist gemäß einer besonders bevorzugten Weiterbildung eine horizontale Teilbarkeit des Transportkanals vorgesehen. Im ausgebauten Zustand kann dann der eine Teil des Transportkanals vom anderen Teil, beispielsweise an Schraubverbindungen, gelöst werden, so daß der Innenraum und damit die Stopfschnecke leicht zugänglich ist. Abfallpartikel, die zum Beispiel zu einem Verklemmen der Stopfschnecke geführt haben, können sodann leicht entfernt werden. Und der Transportkanal kann anschließend wieder geschlossen und mittels der Fahreinrichtung in seine Position im Gehäuse zurückgeführt werden.To remove blockages and / or particularly quickly to ensure a rapid replacement of the stuffing screw, is a horizontal according to a particularly preferred development Divisibility of the transport channel is provided. In the expanded The state of one part of the transport channel can then detached from the other part, for example on screw connections be so that the interior and thus the stuffing screw is easily accessible. Waste particles that, for example jamming of the stuffing screw can then can be easily removed. And the transport channel can then closed again and by means of the driving device be returned to its position in the housing.

Demgemäß zeichnet sich ein Verfahren zur Inspektion des Inhalts eines Abfall-Transportkanals erfindungsgemäß dadurch aus, daß man

  • a) den horizontal geteilten Transportkanal vom Gehäuse löst und mittels einer Fahreinrichtung wegfährt sowie
  • b) den Transportkanal öffnet.
    • Accordingly, a method for inspecting the content of a waste transport channel according to the invention is characterized in that
  • a) the horizontally divided transport channel detaches from the housing and moves away by means of a driving device and
  • b) the transport channel opens.

    • Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments are in the subclaims featured.

    Ausführungsbeispiele der Erfindung werden im folgenden anhand von zwei Figuren näher erläutert. Es zeigen:

  • Figur 1 eine Transporteinrichtung für Abfall als Teil einer Schwelbrenn-Anlage in einem Längsschnitt und
  • Figur 2 einen Blick in Richtung II-II entlang der Stopfschnecke von Figur 1.
    • Exemplary embodiments of the invention are explained in more detail below with reference to two figures. Show it:
  • Figure 1 shows a transport device for waste as part of a smoldering plant in a longitudinal section and
  • 2 shows a view in the direction II-II along the stuffing screw of FIG. 1.

    • Nach Figur 1 ist eine Transporteinrichtung 2 für Abfall A vorgesehen, bei der ein Abfall-Zuführschacht 4 über lösbare Befestigungsmittel 6 an einen Transportkanal 8 angeschlossen ist. Der Transportkanal 8 ist hier als Stopfschnecken-Trog ausgebildet. Er hat einen runden, bevorzugt aber einen polygonalen Querschnitt. Der Transportkanal 8 mündet in ein Gehäuse 10, im vorliegenden Fall in einen Pyrolysereaktor. Dabei handelt es sich um eine sich um ihre Längsachse drehende Schweltrommel, die mit einer größeren Anzahl von Heizrohren 12 parallel zur Längsachse ausgerüstet ist.According to Figure 1 is a transport device 2 for waste A. provided, in which a waste feed shaft 4 via detachable Fastening means 6 connected to a transport channel 8 is. The transport channel 8 is here as a stuffing screw trough educated. It has a round, but preferably a polygonal Cross-section. The transport channel 8 opens into a housing 10, in the present case in a pyrolysis reactor. Here it is a rotating around its longitudinal axis Smoldering drum with a larger number of heating pipes 12 is equipped parallel to the longitudinal axis.

    Im Inneren des im Normalbetrieb feststehenden Transportkanals 8 ist eine Stopfschnecke 14 angeordnet, die sich in dessen Längsrichtung erstreckt. Die Welle 16 der Stopfschnecke 14 ist über ein Getriebe 18 von einem Motor 20 angetrieben. Der Abfall-Zuführschacht 4 ist seitlich vom Transportkanal 8 an dessen Ende angeordnet.Inside the transport channel, which is fixed during normal operation 8, a stuffing screw 14 is arranged, which is in the Extends in the longitudinal direction. The shaft 16 of the stuffing screw 14 is driven by a motor 20 via a transmission 18. Of the Waste feed shaft 4 is on the side of the transport channel 8 its end arranged.

    Von Bedeutung ist nun, daß die Einheit aus Stopfschnecke 14 und Transportkanal 8 am Gehäuse 10 lösbar befestigt ist. Hierzu dienen schließbare Ringdichtungen 22, die einerseits am linken Ende eines Aufgaberohrs 24, das den Transportkanal 8 umgibt, und andererseits an einem Flansch 26 am Transportkanal 8 befestigt sind. Von Bedeutung ist weiterhin, daß die Einheit aus Stopfschnecke 14 und Transportkanal 8 auf einem Fahrgestell oder einer Fahreinrichtung 28 gelagert ist. Zu dieser relativ schweren Einheit 14, 8 gehören hier noch das Getriebe 18 und der Motor 20. Bei der Fahreinrichtung 28 handelt es sich um eine Art Wagen oder eine Lafette, die auf Schienen 30 horizontal beweglich ist. Es können zwei oder mehr Schienen 30 vorgesehen sein. Die Fahreinrichtung 28 besitzt mindestens drei, bevorzugt aber vier Räder 31. Die horizontale Bewegbarkeit ist durch einen Doppelpfeil 32 angedeutet. Die Einrichtung 28 kann von Hand durch eine Hilfseinrichtung, bevorzugt aber durch eine Maschine (nicht dargestellt) bewegt werden. Die genannte Einheit 14, 8, 18, 20 ist somit, nachdem die Verbindungsstellen 6, 22 gelöst sind, vom Gehäuse 10 entfernbar. In der entfernten Position läßt sich der Transportkanal 8 samt Stopfschnecke 14 relativ leicht inspizieren und reinigen. Blockaden können so behoben werden. Auch ist im ausgebauten Zustand ein leichtes Auswechseln der Stopfschnecke 14 möglich. Wichtig ist aber, daß blockierende Abfallteile schnell aus der Stopfschnecke 14 entfernt werden können.It is important that the unit from the auger 14th and transport channel 8 is releasably attached to the housing 10. Lockable ring seals 22 serve this purpose, on the one hand at the left end of a feed tube 24 that the transport channel 8 surrounds, and on the other hand on a flange 26 on the transport channel 8 are attached. It is also important that the Unit consisting of screw auger 14 and transport channel 8 on one Chassis or a driving device 28 is mounted. To this relatively heavy unit 14, 8 still belongs here Transmission 18 and the motor 20. In the driving device 28 acts it is a kind of carriage or a carriage which is mounted on Rails 30 is horizontally movable. There can be two or more rails 30 may be provided. The driving device 28 has at least three, but preferably four wheels 31. The horizontal Movability is indicated by a double arrow 32. The device 28 can be manually operated by an auxiliary device, but preferably by a machine (not shown) be moved. The unit 14, 8, 18, 20 mentioned is thus, after the connection points 6, 22 are released, from Housing 10 removable. In the distant position you can inspect the transport channel 8 together with the stuffing screw 14 relatively easily and clean. Blockages can be removed in this way. Even when removed, it is easy to replace the Darning screw 14 possible. But it is important that blocking Waste parts can be quickly removed from the stuffing screw 14 can.

    Die einzelnen Verfahrensschritte sind somit folgende:

  • 1. Drehbewegung des Gehäuses 10 abstellen;
  • 2. Schneckendichtung 22 und Verbindung 6 lösen;
  • 3. Stopfschnecke 14 samt Transportkanal 8 aus dem Aufgaberohr 24 herausfahren;

  • 6. Transportkanal 8 schließen;
  • 7. Stopfschnecke 14 samt Transportkanal 8 zurückfahren;
  • 8. Schneckendichtung 22 und Verbindung 6 wieder befestigen.
    • The individual process steps are therefore as follows:
  • 1. Turn off the rotational movement of the housing 10;
  • 2. Loosen screw seal 22 and connection 6;
  • 3. Remove the stuffing screw 14 together with the transport channel 8 from the feed pipe 24;
  • 4. Open the transport channel 8, in particular according to FIG. 2;

  • 6. Close the transport channel 8;
  • 7. Retract the screw auger 14 together with the transport channel 8;
  • 8. Fasten screw seal 22 and connection 6 again.

    • Nach Figur 1 wird der Abfall A in der sich drehenden Schweltrommel 10 mittels der Heizrohre 12 indirekt von Heizgas h beheizt. Dieses Heizgas h wird über ein ortsfestes Heizgas-Eintrittsgehäuse 40 in eine heiße Heizgaskammer 42 im Inneren der Schwelltrommel 10 geleitet. An deren Rohrbodenwand 44 sind die parallel verlaufenden Heizrohre 12 mit einem Ende befestigt. Das andere Ende ist in einer Rohrbodenwand 46 festgemacht, die die eine Wand einer kalten Heizgaskammer 48 bildet. Von dieser kalten Heizgaskammer 48 gelangt das Heizgas h über ein Heizgas-Austrittsgehäuse 50 in einen Auslaß. Zur Abdichtung des Heizgas-Austrittsgehäuses 52 gegen das drehende Rohr sind Ringdichtungen 54, 56 vorgesehen. Entsprechend sind zur Abdichtung des Heizgas-Eintrittsgehäuses 40 Ringdichtungen 58, 60 vorgesehen. Vom Innenraum der Schweltrommel 10, genauer: vom Rohrboden 44, ist ein Austragsrohr 62 in den Innenraum einer feststehenden Austragsvorrichtung 64 geleitet. Das über das Austragsrohr 62 in diese Austragsvorrichtung 64 gelangende Schwelgut wird hier in Schwelgas s und Reststoff r aufgeteilt. Letzterer kann gemäß dem Schwelbrenn-Verfahren mittels einer geeigneten Vorrichtung (nicht gezeigt) in verschiedene Fraktionen aufgeteilt und aussortiert werden, bevor er einer Verbrennung in einer (nicht gezeigten) Hochtemperatur-Brennkammer zugeführt wird. Um die Austragsvorrichtung 64 von der Drehung der Schweltrommel 10 zu entkoppeln, ist an der Austragsvorrichtung 64 eine lösbare Ringdichtung 66 angeordnet.According to Figure 1, the waste A in the rotating smoldering drum 10 by means of the heating tubes 12 indirectly from heating gas h heated. This heating gas h is via a stationary heating gas inlet housing 40 into a hot heating gas chamber 42 inside the swelling drum 10 passed. On the tube sheet wall 44 are the parallel heating tubes 12 with one end attached. The other end is in a tube sheet wall 46 the one wall of a cold heating gas chamber 48 forms. The heating gas passes from this cold heating gas chamber 48 h via a heating gas outlet housing 50 into an outlet. To seal the heating gas outlet housing 52 against that rotating tube ring seals 54, 56 are provided. Corresponding are for sealing the heating gas inlet housing 40 Ring seals 58, 60 are provided. From the interior of the smoldering drum 10, more precisely: from the tube sheet 44, is a discharge tube 62 in the interior of a fixed discharge device 64 headed. That through the discharge pipe 62 into this discharge device 64 smoldering gas is here in smoldering gas s and residual r divided. The latter can be according to the smoldering method using a suitable device (not shown) divided into different fractions and sorted out before being burned in a (not shown) High temperature combustion chamber is supplied. To the Discharge device 64 from the rotation of the smoldering drum 10 to decouple is a releasable on the discharge device 64 Ring seal 66 arranged.
