Abstract

A heating chamber is rotatable about its longitudinal axis and contains a number of heating tubes orientated parallel to each other. Solid material which is lifted up during the rotation can become detached from the heating tubes and upon impact can lead to damage to heating tubes which are situated below. In order to prevent such an occurrence, baffle shells are provided on the heating tubes. The baffle shells are formed of a resistant material and offer protection against surface damage. The heating tubes are preferably disposed in radially orientated rows.

Description

Die Erfindung bezieht sich auf eine um ihre Längsrichtung drehbare Heizkammer für Festgut, insbesondere auf eine Schwelkammer für Abfall, mit einer Anzahl von im Innenraum liegenden Heizrohren.The invention relates to a around its longitudinal direction rotatable heating chamber for solid goods, especially on a Smoldering chamber for waste, with a number of in the interior lying heating pipes.

Die Heizkammer wird zur thermischen Abfallentsorgung eingesetzt, insbesondere nach dem Schwelbrenn-Verfahren.The heating chamber is used for thermal waste disposal, 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 EP-A-0 302 310 sowie in der DE-A-38 30 153 beschrieben. Die Anlage zur thermischen Abfallentsorgung nach dem Schwelbrenn-Verfahren enthalt als wesentliche Komponenten eine Schwelkammer (Pyrolysereaktor) und eine Hochtemperatur-Brennkammer. Die Schwelkammer setzt den über eine Abfall-Transporteinrichtung aufgegebenen Abfall in Schwelgas und Pyrolysereststoff um. Das Schwelgas und der Pyrolysereststoff werden sodann nach geeigneter Aufarbeitung dem Brenner der Hochtemperatur-Brennkammer zugeführt. In der Hochtemperatur-Brennkammer entsteht schmelzflüssige Schlacke, die über einen Abzug entnommen wird 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.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 EP-A-0 302 310 and in DE-A-38 30 153. The plant for thermal waste disposal contains according to the smoldering process as essential Components a smoldering chamber (pyrolysis reactor) and one High temperature combustion chamber. The smoldering chamber puts the over a waste transportation facility in abandoned waste Smoldering gas and pyrolysis residue. The carbonization gas and the pyrolysis residue are then after appropriate workup fed to the burner of the high temperature combustion chamber. In the High temperature combustion chamber creates molten slag, which is removed via a fume hood and which after cooling in glazed form is present. The resulting flue gas is over 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 installed.

Als Schwelkammer (Pyrolysereaktor) wird in der Regel eine sich um ihre Längsachse drehende Schweltrommel eingesetzt, die innen eine Anzahl von parallelen Heizrohren aufweist, an denen der Abfall weitgehend unter Luftabschluß aufgeheizt wird. Die Schweltrommel dreht sich dabei um ihre Längsachse. As a smoldering chamber (pyrolysis reactor) is usually one smoldering drum rotating around its longitudinal axis, which has a number of parallel heating pipes on the inside where the waste is largely heated in the absence of air becomes. The smoldering drum rotates about its longitudinal axis.

Vorzugsweise ist die Längsachse der Schweltrommel etwas gegenüber der Horizontalen geneigt, so daß sich das Schwelgut am Ausgang der Schweltrommel ansammeln und von dort leicht ausgetragen werden kann. Beim Drehen fällt der emporgehobene Abfall auf die darunterliegenden Heizrohre. Da der Abfall schwere Komponenten, wie zum Beispiel Steine, Flaschen, Keramikteile, Eisenteile, enthalten kann, besteht die Gefahr, daß dabei die Heizrohre beschädigt werden und erodieren. Beim Aufprall können von der Oberfläche der Heizrohre kleine Partikel abplatzen. Der Ersatz der Heizrohre ist zeit- und kostenaufwendig.The longitudinal axis of the smoldering drum is preferably somewhat opposite inclined horizontally so that the char is Accumulate at the exit of the smoldering drum and from there easily can be carried out. When turning, the raised one falls Waste on the heating pipes underneath. Because the waste heavy components, such as stones, bottles, ceramic parts, Iron parts, there is a risk that the heating pipes are damaged and eroded. At the Small particles can impact from the surface of the heating pipes flake off. The replacement of the heating pipes is time-consuming and costly.

Der Erfindung liegt die Aufgabe zugrunde, die Heizrohre in einer Heizkammer der eingangs genannten Art gegen Beschädigungen durch herabfallendes Festgut zu schützen und damit deren Standzeit zu erhöhen.The invention has for its object in the heating tubes a heating chamber of the type mentioned against damage to protect by falling solid material and thus their Increase service life.

Diese Aufgabe wird erfindungsgemäß gelöst durch Prallschalen auf den Heizrohren. Die Prallschalen übernehmen die Funktion einer Schutzverkleidung, so daß bei weitgehend ungestörtem Wärmeübergang Beschädigungen der eigentlichen Heizrohre durch herabfallendes Festgut fast vollständig vermieden werden. Ein Austausch der Heizrohre ist somit - wenn überhaupt - erst nach relativ großen Zeitintervallen erforderlich.According to the invention, this object is achieved by impact shells on the heating pipes. The impact shells take over the function a protective cover so that when largely undisturbed Heat transfer Damage to the actual heating pipes falling solid material can be avoided almost completely. A Replacing the heating pipes is therefore - if at all - the first time required after relatively large time intervals.

Bevorzugt können die Prallschalen als halbe Schalen oder Halbschalen ausgebildet sein. Solche Halbschalen lassen sich relativ einfach auf den Heizrohren befestigen, und sie gewähren großflächigen Schutz.The impact shells can preferably be used as half shells or Half shells should be formed. Such half-shells can be relatively easy to attach to the heating pipes, and they allow extensive protection.

Die genannten Prallschalen sind sicher auch ein Kostenfaktor. Außerdem verschlechtert sich an ihrer Stelle der Wärmeübergang ein wenig. Um eine kostengünstige Lösung mit gutem Wärmeübergang bereitzustellen, ist gemäß einer Weiterbildung vorgesehen, daß sich die Prallschalen nur über einen Teil der Gesamtlänge der Heizrohre erstrecken. Bei einer Schwelkammer für Abfall reicht es aus, wenn die Prallschalen sich nur etwa über ein Drittel der Gesamtlänge erstrecken.The baffles mentioned are certainly also a cost factor. In addition, the heat transfer deteriorates in its place a little. A cost-effective solution with good heat transfer is to be made available according to a further training provided that the baffles only over part of the Extend the total length of the heating pipes. With a smoldering chamber for waste, it is sufficient if the impact shells are only about extend over a third of the total length.

Es war bereits dargelegt, daß bei einer Schwelkammer die Längsachse gegenüber der Horizontalen geneigt sein kann. Bei einer solchen Heiz- oder Schwelkammer ist es ausreichend, die Prallschalen nur auf dem tieferen oder unteren Ende der Heizrohre anzubringen. Denn am Ende ergibt sich eine Ansammlung der schwereren Teile des Abfalls und damit in diesem Bereich eine besondere Gefährdung durch herabfallendes Festgut. Die Prallschalen am besonders kritischen unteren Endbereich der Heizrohre verhindern also die Zerstörung der Oberfläche der Heizrohre, zumindest über einen relativ langen Zeitraum hinweg.It had already been shown that in a smoldering chamber the Longitudinal axis can be inclined with respect to the horizontal. At such a heating or smoldering chamber, it is sufficient that Baffles only on the lower or lower end of the heating pipes to attach. Because in the end there is an accumulation of the heavier parts of the waste and therefore in this area a particular risk from falling solid material. The Impact shells at the particularly critical lower end area of the So heating pipes prevent the destruction of the surface of the Heating pipes, at least for a relatively long period of time.

Die Prallschalen bestehen bevorzugt aus Stahl. Sie werden an den Heizrohren angeschweißt, insbesondere zu diesem Zweck jeweils mit Heftnähten versehen.
Nach einer weiteren Ausführungsform ist vorgesehen, daß die Heizrohre in etwa radial ausgerichteten Reihen parallel zueinander angeordnet sind. Um einen besonders wirksamen Schutz zu erzielen, ist hierbei vorgesehen, daß die Prallschalen die oberen Teile der Heizrohre überdecken, wenn die Heizrohre in Drehrichtung der Heizkammer um 30 ° bis 60 °, bevorzugt um 45 °, von der tiefsten Position der Heizrohre entfernt sind.The impact shells are preferably made of steel. They are welded to the heating pipes, especially with stitching for this purpose.
According to a further embodiment it is provided that the heating tubes are arranged parallel to one another in approximately radially aligned rows. In order to achieve a particularly effective protection, it is provided that the baffles cover the upper parts of the heating tubes when the heating tubes are in the direction of rotation of the heating chamber by 30 ° to 60 °, preferably 45 °, from the lowest position of the heating tubes.

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

  • Figur 1 eine Schwelanlage für Abfall, die im Rahmen des Schwelbrenn-Verfahrens eingesetzt werden kann, in einer prinzipiellen Schnittdarstellung und
  • Figur 2 einen Querschnitt durch eine Schwelkammer für Abfall, wobei die Heizrohre in Reihen, die im wesentlichen radial ausgerichtet sind, parallel zueinander angeordnet sind.
    • Exemplary embodiments of the invention are explained in more detail below with reference to two figures. Show it:
  • Figure 1 shows a smoldering plant for waste, which can be used in the smoldering process, in a basic sectional view and
  • 2 shows a cross section through a smoldering chamber for waste, the heating tubes being arranged parallel to one another in rows which are essentially radially aligned.

    • Nach Figur 1 wird fester Abfall A über eine Zufuhr- oder Aufgabeeinrichtung 2 und eine Schnecke 4, die von einem Motor 6 angetrieben wird, in einen Pyrolysereaktor oder eine Schwelkammer 8 der Länge l eingebracht. Die Schwelkammer 8 ist im Ausführungsbeispiel eine um ihre Längsachse 10 (durch nicht gezeigte Antriebsmittel) drehbare Schwel- oder Pyrolysetrommel, die bei 300 bis 600 °C arbeitet, weitgehend unter Sauerstoffabschluß betrieben wird und neben flüchtigem Schwelgas s einen weitgehend festen Pyrolysereststoff f erzeugt. Es handelt sich dabei um eine innenberohrte Schweltrommel 8 mit einer Vielzahl von parallel zueinander ausgerichteten Heizrohren 12, von denen nur zwei gezeigt sind. Der am einen Ende vorgesehene Einlaß für Heizgas h ist mit 14 und der am anderen Ende vorgesehene Auslaß für das Heizgas h ist mit 16 bezeichnet. Die Längsachse 10 der Schwelkammer 8 ist bevorzugt gegenüber der Horizontalen geneigt, so daß das rechts gelegene Ende tiefer liegt als der links gezeigte Einlaß für den Abfall A. Der Pyrolysetrommel 8 ist ausgangs- oder austragsseitig eine Austragsvorrichtung 18 nachgeschaltet, die mit einem Schwelgas-Abzugsstutzen 20 für den Abgang des Schwelgases s und mit einem Pyrolysereststoffausgang 22 für die Abgabe des festen Pyrolysereststoffes f versehen ist. Eine an den Schwelgas-Abzugsstutzen 20 angeschlossene (nicht gezeigte) Schwelgasleitung kann mit dem Brenner einer Hochtemperatur-Brennkammer verbunden sein.According to Figure 1, solid waste A via a feed or feed device 2 and a worm 4 driven by a motor 6 is driven into a pyrolysis reactor or a smoldering chamber 8 of length l introduced. The smoldering chamber 8 is in the Embodiment one about its longitudinal axis 10 (by not drive means shown) rotatable smoldering or pyrolysis drum, which works at 300 to 600 ° C, largely with the exclusion of oxygen is operated and in addition to volatile carbonization gas s produces a largely solid pyrolysis residue f. It deals is an inner tube-smoked drum 8 with a Large number of heating pipes aligned parallel to each other 12, of which only two are shown. The one at one end intended inlet for heating gas h is 14 and the other End provided outlet for the heating gas h is designated 16. The longitudinal axis 10 of the smoldering chamber 8 is preferred inclined to the horizontal so that the one on the right End is lower than the inlet for the Waste A. The pyrolysis drum 8 is on the output or discharge side a discharge device 18 connected downstream with a carbonization gas discharge nozzle 20 for the discharge of the carbonization gas s and with a pyrolysis residue outlet 22 for delivery of the solid pyrolysis residue f is provided. One to the Smoldering gas discharge nozzle 20 connected (not shown) Smoldering gas line can use the burner of a high temperature combustion chamber be connected.

    Von besonderer Bedeutung ist es nun, daß die Heizrohre 12 im eigentlichen Schwelteil, der rechts liegt, mit Prallschalen 26 belegt oder versehen sind. Diese Prallschalen 26 erstrecken sich etwa über 1/3 l, also über ein Drittel der Gesamtlänge 1 der Heizrohre 12. Die Gesamtlänge kann zum Beispiel 20 m und der jeweilige Durchmesser 8 bis 10 cm betragen. Die Prallschalen 26 sind bevorzugt halbrunde Mantelstücke oder Halbschalen. Sie bestehen aus Stahl und sind mit Heftnähten auf den Stahl-Heizrohren 12 angeschweißt. Die Prallschalen 26 können sich auch über einen größeren Teil der Gesamtlänge l oder aber über die Gesamtlänge l erstrecken. It is of particular importance that the heating tubes 12 in actual smoldering part, which is on the right, with impact shells 26 are occupied or provided. These baffles 26 extend about 1/3 l, i.e. over a third of the total length 1 of the heating pipes 12. The total length can for example 20 m and the respective diameter is 8 to 10 cm. The baffles 26 are preferably semicircular jacket pieces or half shells. They are made of steel and are with Seams welded onto the steel heating tubes 12. The Baffles 26 can also over a larger part of the Total length l or extend over the total length l.

    Auf jeden Fall schützen sie die Heizrohre 12 im rechts gelegenen gefährdeten Bereich vor herabfallendem Festgut A in Form von Steinen, Eisen-, Keramik- und Porzellanteilen Glasscherben und ähnlichem.In any case, they protect the heating pipes 12 on the right endangered area in front of falling solid material A in Form of stones, iron, ceramic and porcelain parts broken glass and the like.

    Die Prallschalen 26 werden vor dem Einbringen der Heizrohre 12 in die Schwelkammer 8 montiert. Die Heizrohre 12 mit aufgeschweißten Prallschalen 26 werden von rechts durch entsprechend große Öffnungen in der rechten Endplatte 28 in den Innenraum der Schwelkammer 8 eingebracht und dann an beiden Endplatten 28, 30 verschweißt.The baffles 26 are before the heating pipes are inserted 12 mounted in the smoldering chamber 8. The heating tubes 12 with welded on Baffles 26 are correspondingly from the right large openings in the right end plate 28 in the interior introduced the smoldering chamber 8 and then on both End plates 28, 30 welded.

    Nach Figur 2 umfaßt eine innenberohrte Schwelkammer 8, deren Längsachse 10 wiederum schräg angeordnet sein kann, eine Vielzahl von parallel zueinander angeordneten Heizrohren 12. Die Heizkammer 8 ist in Richtung des Pfeiles 32 um die Längsachse 10 drehbar. Insgesamt sind im Ausführungsbeispiel 8 x 4 = 32 Heizrohre 12 vorgesehen. Es können aber deutlich mehr sein, zum Beispiel mehr als hundert. Sie sind in acht Reihen I bis VIII von jeweils vier Heizrohren 12 in radialer Richtung nebeneinander angeordnet. Jedes der Heizrohre 12 ist mit einer widerstandsfähigen Prallschale 26 versehen. In der dargestellten Rotations-Stellung der Schwelkammer 8, die beispielsweise einen Durchmesser von 2,90 m aufweisen kann, ist die Reihe VI unter einem Winkel von etwa 45° zur Horizontalen 40 und - in Drehrichtung der Heizkammer 8 - unter einem Winkel von etwa 45 ° zur tiefsten Reihe V positioniert. Aus Figur 2 ist ersichtlich, daß in dieser 45°-Position die Prallschalen 26 der Heizrohre 12 in der Reihe VI die oberen Teile der Heizrohre 12 überdecken. Die Rotationsstellung, in der diese Ausrichtung erreicht ist, kann in einem bevorzugten Bereich von 30° bis 60° liegen. Auf diese Weise wird praktisch vollständiger Schutz der Heizrohre 12 vor herabfallenden Brocken des Abfalls A gewährleistet. Es ist nämlich zu beachten, daß durch die Rotation in Richtung des Pfeiles 32 der Abfall A angehoben wird, und daß sich der Abfall A mit zunehmender Steighöhe in zunehmendem Maße von der Auflage auf den Heizrohren 12 löst und herabfällt. Die genaue Position, in der die gewünschte Ausrichtung der haubenförmigen Schutzschalen 26 nach oben vorliegen sollte, ist natürlich von Anzahl und Krümmung der Reihen I bis VIII, von der Art des Abfalls A, vom Abstand der einzelnen Heizrohre 12 voneinander und von weiteren Faktoren abhängig. Bei einer großen Schweltrommel 8 kann somit die gewünschte Ausrichtung nach oben bei einem Winkel angebracht sein, der viel kleiner ist als 30° (im bevorzugten Bereich von 30° bis 45°).According to FIG. 2, an inner-tube smoldering chamber 8 comprises Longitudinal axis 10 can in turn be arranged obliquely, a A plurality of heating tubes 12 arranged parallel to one another. The heating chamber 8 is in the direction of arrow 32 about the longitudinal axis 10 rotatable. In total, 8 x 4 in the exemplary embodiment = 32 heating tubes 12 are provided. But it can do much more be, for example, more than a hundred. They are in eight rows I to VIII of four heating tubes 12 in the radial direction arranged side by side. Each of the heating tubes 12 is with provided a resistant impact shell 26. In the illustrated Rotational position of the smoldering chamber 8, for example can have a diameter of 2.90 m row VI at an angle of approximately 45 ° to the horizontal 40 and - in the direction of rotation of the heating chamber 8 - at an angle positioned from about 45 ° to the deepest row V. From figure 2 it can be seen that in this 45 ° position the impact shells 26 of the heating tubes 12 in row VI the upper parts cover the heating pipes 12. The rotational position in which this alignment can be achieved in a preferred range from 30 ° to 60 °. This way it becomes practical complete protection of the heating tubes 12 against falling Chunks of waste A guaranteed. It should be noted that that by the rotation in the direction of arrow 32 Waste A is raised, and that waste A increases with increasing Rising height increasingly from the support to the Heating tubes 12 loosens and falls. The exact position in the desired orientation of the hood-shaped protective shells 26 should be up, is of course from Number and curvature of rows I to VIII, of the type of Waste A, the distance between the individual heating tubes 12 from each other and dependent on other factors. With a big one Smolder drum 8 can thus the desired orientation at the top at an angle that is much smaller than 30 ° (in the preferred range of 30 ° to 45 °).
