Description

Die Erfindung betrifft eine Vorrichtung zum Verbrennen von in einem Medienstrom enthaltenen Störstoffen. Die Vorrichtung besteht aus einem zylindrischen Behälter mit einem Eintrittsstutzen und einem Austrittsstutzen für den Medienstrom. Dieser ist durch ein im Innern des Behälters zylinderförmig angeordnetes und sich axial erstreckendes ringförmiges Bündel aus Wärmetauscherrohren, die sich über den wesentlichen Teil der Länge des Gehäuses erstrecken, von einer Vorkammer in eine Ringkammer einleitbar. Diese umschließt einen an einer Stirninnenseite des Behälters angeordneten Brenner und geht in ein konzentrisch im Behälter angeordnetes Rauchgasmischrohr über. Das Rauchgasmischrohr mündet in eine Haupt-Brennkammer, an deren Ende ein Ringraum vorgesehen ist, von dem aus der Medienstrom über die Wärmetauscherrohre dem Austrittsstutzen zuleitbar ist.The invention relates to a device for burning contaminants contained in a media stream. The device consists of a cylindrical container with an inlet connection and an outlet connection for the media flow. This can be introduced from a prechamber into an annular chamber by means of a cylindrical bundle of heat exchanger tubes which is arranged in the interior of the container and extends axially and extends over the substantial part of the length of the housing. This surrounds a burner arranged on an inside face of the container and merges into a flue gas mixing tube arranged concentrically in the container. The flue gas mixing pipe opens into a main combustion chamber, at the end of which an annular space is provided, from which the media flow can be fed to the outlet connection via the heat exchanger pipes.

Eine derartige, aus der EP-A-40 690 bekannte Vorrichtung ist zur Beaufschlagung mit dem Medienstrom über Rohrleitungen mit einer externen Fördereinrichtung in Form eines Gebläses verbunden. Da Klappen zum alternativen Betrieb mit oder zum Zumischen von Frischluft stets auf der Saugseite des den Medienstrom fördernden Gebläses angeordnet werden müssen, sind auch diese Klappen und Mischeinrichtungen gemeinsam mit dem Gebläse oder weiter noch als dieses von der Vorrichtung entfernt anzuordnen.Such a device, known from EP-A-40 690, is connected to an external conveying device in the form of a blower for the application of the media flow via pipelines. Since flaps for alternative operation with or for admixing fresh air must always be arranged on the suction side of the blower that promotes the media flow, these flaps and mixing devices are also to be arranged together with the blower or further away from the device.

Häufig befinden sich das Gebläse und die zusätzlichen Komponenten für die Zumischung von Frischluft in einem Gebäude, während die Verbrennungsanlage selbst außerhalb des Gebäudes aufgestellt wird.The blower and the additional components for adding fresh air are often all in one Building, while the incinerator itself is installed outside of the building.

Da alternative Betriebsluft beispielsweise für den Anfahrbetrieb, für den Zumischbetrieb oder für den sogenannten "Stand-by"-Betrieb immer zur Verfügung stehen muß und es sich dabei oft um sehr beträchtliche Luftmengen handelt, sind zum Beispiel bei einer Aufstellung des Gebläses im Gebäudeinnern noch zusätzliche Rohrverbindungen herzustellen, wenn alternative Betriebsluft von außen angesaugt werden soll. In aller Regel ist der Aufwand für die Unterbringung der sogenannten peripheren Komponenten dieser Anlagen erheblich: Freier Raum ist erforderlich, Gerüste und Gestelle sind zu errichten, lange Rohrleitungen mit großen Querschnitten sind zu verlegen, entsprechende Wärmeisolierungen sind erforderlich, und nicht zuletzt sind Schalldämmmaßnahmen unumgänglich. Der Platzbedarf geht zu Lasten der eigentlichen Produktionssysteme, die als wichtiger angesehen werden. Zudem ist die von diesen Gebläsen verursachte Lärmbelästigung in aller Regel beträchtlich, da es sich meist um sehr laute Hochleistungsgebläse handelt. Während der Körperschall noch mit begrenztem Aufwand gedämmt werden kann, läßt sich der Luftschall dieser Gebläse nur durch einen hohen Aufwand in erträglichen Grenzen halten. Die klassischen Ausblas-Kulissen können hier nicht eingesetzt werden, da sie durch die Störstoffe und andere Stoffe versotten würden und sie der Temperatur des Abgases nicht standhalten bzw. weil die erforderlichen flexiblen, d.h. schalloffenen Anschlüsse auf der Druckseite des Gebläses einen Ausblas-Schalldämpfer nicht zulassen. Das Gesamtsystem aus der eigentlichen Verbrennungsanlage und den peripheren Komponenten ist daher insgesamt sehr kostenaufwendig.Since alternative operating air, for example for start-up operation, for admixing operation or for the so-called "stand-by" operation, must always be available and it is often a very considerable amount of air, there are additional ones, for example, when the blower is installed inside the building Establish pipe connections if alternative operating air is to be drawn in from the outside. As a rule, the effort involved in accommodating the so-called peripheral components of these systems is considerable: free space is required, scaffolding and frames have to be erected, long pipelines with large cross sections have to be laid, appropriate thermal insulation is required, and last but not least, sound insulation measures are essential. The space requirement is at the expense of the actual production systems, which are regarded as more important. In addition, the noise pollution caused by these fans is generally considerable, since they are usually very loud, high-performance fans. While the structure-borne noise can still be insulated with limited effort, the airborne noise of these fans can only be kept within tolerable limits by a great deal of effort. The classic blow-out backdrops cannot be used here because they would sprout due to the contaminants and other substances and they do not withstand the temperature of the exhaust gas or because of the Do not allow the required flexible, ie sound-open connections on the pressure side of the blower a blow-out silencer. The overall system consisting of the actual incineration plant and the peripheral components is therefore very expensive overall.

Aus der US-A-4,324,545 ist auch bereits eine Verbrennungsvorrichtung bekannt, bei der ein Gebläse gegenüberliegend von einem Brenner an der Stirninnenseite eines Gehäuses befestigt ist. Dabei ist das Gebläse jedoch nicht mit einem an die Gebläsesaugseite angeschlossenen Eintrittsstutzen versehen, über den ein Medienstrom in die Vorrichtung eintritt. Der Eintrittsstutzen des Gebläses ist statt dessen Bestandteil einer Mischkammer, die stromabwärts liegt und an welche sich das Gebläse anschließt. In diesem Vorrichtungsbereich ist der Medienstrom in einem hochaufgeheizten Zustand, weswegen das Gebläse in einer sehr aufwendigen Weise hitzebeständig ausgeführt werden muß. Dazu zählt insbesondere auch eine Kühlung der Wellenlager im Bereich der Wellendurchführung. Im Falle einer nicht hitzebeständigen Ausführung des Gebläses wäre die vorbekannte Vorrichtung nicht funktionsfähig.From US-A-4,324,545 a combustion device is already known, in which a fan is attached opposite a burner on the front inside of a housing. In this case, however, the blower is not provided with an inlet connection, which is connected to the blower suction side and via which a media flow enters the device. Instead, the inlet connection of the blower is part of a mixing chamber which is located downstream and to which the blower is connected. In this device area, the media flow is in a highly heated state, which is why the fan must be designed to be heat-resistant in a very complex manner. In particular, this also includes cooling the shaft bearings in the area of the shaft bushing. If the blower were not heat-resistant, the previously known device would not function.

Der Erfindung liegt die Aufgabe zugrunde, eine Verbrennungsvorrichtung der eingangs beschriebenen Art vorzuschlagen, die insgesamt weniger Raum beansprucht und sich kostengünstiger herstellen wie auch betreiben läßt.The invention has for its object to propose a combustion device of the type described above, which takes up less space overall and can be manufactured and operated more cost-effectively.

Zur Lösung dieser Aufgabe wird von einer Vorrichtung der im Oberbegriff des Anspruchs 1 genannten gattungsgemäßen Art ausgegangen, welche erfindungsgemäß die im kennzeichnenden Teil desselben angegebenen Merkmale aufweist.To achieve this object, a device of the generic type mentioned in the preamble of claim 1 is assumed, which according to the invention has the features specified in the characterizing part of the same.

Die erfindungsgemäße Integration der Fördereinrichtung im zylindrischen Behälter führt zu zahlreichen Vorteilen gegenüber konventionellen Vorrichtungen. So entfällt ein gesonderter Aufstellungsplatz und -raum für das Prozeßgebläse. Damit entfallen auch Rohrleitungen zwischen dem Gebläse und der Vorrichtung und alle damit verbundenen Kosten hinsichtlich baulicher Veränderungen, Wärmeisolation, Inspektion und Wartung. Die erfindungsgemäße Anordnung der Fördereinrichtung an der dem Brenner gegenüberliegenden Stirnseite des Behälters macht auch eine Wärmeisolierung der Fördereinrichtung entbehrlich.The inventive integration of the conveyor in the cylindrical container leads to numerous advantages over conventional devices. This eliminates the need for a separate place and space for the process fan. This also eliminates pipelines between the blower and the device and all associated costs with regard to structural changes, thermal insulation, inspection and maintenance. The arrangement of the conveyor on the end of the container opposite the burner also makes thermal insulation of the conveyor unnecessary.

Ebenso bedarf die Fördereinrichtung durch die Integration im Behälterinnern keiner Schallisolierung. Ausblasgeräusche werden zudem gedämpft durch die große Masse der Wärmetauscherrohre auf der Druckseite der Fördereinrichtung. Weiterhin kann es auch nicht zu einer Kondensatbildung durch Wärmeverluste an den Wandteilen der Fördereinrichtung kommen, da sowohl das Gebläse wie auch dessen Ansaugleitung innerhalb des Behälters eine optimale Erwärmung erfahren. Selbst beim Betrieb mit Frischluft während des Anfahrens der Vorrichtung und während des Stand-by-Betriebs bleiben die Fördereinrichtung und ihre Ansaugleitung ausreichend aufgeheizt, da genügend Strahlungswärme von der Brennkammer her zur Verfügung steht oder auch im erforderlichen Umfang erzeugt werden kann. Deshalb verfügt die erfindungsgemäße Vorrichtung auch noch nach längeren Stillstandszeiten im Abgasbereich über ausreichende Temperaturen für die schnelle Schaltung auf den Abgasbetrieb. Da die abgasführenden Rohrleitungen bis in den Behälter hinein unter Unterdruck stehen, wirkt sich eine Leckage in diesen Rohrleitungen auch nicht gefährlich oder störend aus.Likewise, due to the integration in the interior of the container, the conveyor device does not require sound insulation. Blow-out noises are also dampened by the large mass of the heat exchanger tubes on the pressure side of the conveyor. Furthermore, condensation cannot form as a result of heat losses on the wall parts of the conveying device, since both the fan and its suction line are optimally heated within the container. Even when operating with fresh air during the start-up of the device and during stand-by operation, the conveying device and its suction line remain sufficiently heated because sufficient radiant heat is available from the combustion chamber or can be generated to the required extent. Therefore, the device according to the invention also has sufficient temperatures for rapid switching to exhaust gas operation even after longer downtimes in the exhaust gas area. Since the exhaust gas-carrying pipelines are under negative pressure right into the tank, leakage in these pipelines is also not dangerous or disruptive.

Die erfindungsgemäße Vorrichtung kann in sehr komptakter Form als betriebsfertige Anlage herstellerseitig vormontiert werden. Dadurch lassen sich erhebliche Montagekosten am Aufstellungsort der Vorrichtung vermeiden.The device according to the invention can be preassembled by the manufacturer in a very compact form as a ready-to-use system. This can avoid considerable assembly costs at the installation site of the device.

Nach einer Ausgestaltung der Erfindung besteht die im Innern des Behälters angeordnete Fördereinrichtung aus einem Radialgebläse, dessen Antrieb auf der Stirnaußenseite des Behälters angeordnet ist.According to one embodiment of the invention, the conveyor device arranged inside the container consists of a radial fan, the drive of which is arranged on the outside of the container.

Während das Radialgebläse selbst lediglich Temperaturen ausgesetzt ist, die eine Kondensatbildung verhindern, ist der Antrieb für das Radialgebläse gänzlich den Einflüssen des Abgases entzogen.While the radial fan itself is only exposed to temperatures that prevent the formation of condensate, the drive for the radial fan is completely removed from the influences of the exhaust gas.

Nach einer weiteren Ausgestaltung der Erfindung ist ein Laufrad des Radialgebläses mit einem Gehäuse umgeben, dessen radial in die Vorkammer mündender Auslaß durch einen Ringspalt gebildet ist.According to a further embodiment of the invention, an impeller of the radial fan is surrounded by a housing, the outlet of which radially opens into the prechamber is formed by an annular gap.

Bedingt durch den großen Raum außerhalb des Gebläses, in Verbindung mit dieser Ausgestaltung, erfolgt eine intensive Verteilung des zugeführten Medienstroms über den gesamten Bereich der Vorkammer, so daß von dort aus sämtliche Wärmetauscherrohre mit einem völlig übereinstimmenden Druck und Volumenstrom beaufschlagt werden können.Due to the large space outside the fan, in connection with this configuration, there is an intensive distribution of the supplied media flow over the entire area of the prechamber, so that from there all heat exchanger tubes can be acted upon with a completely identical pressure and volume flow.

Ist schließlich nach einer weiteren Ausgestaltung der Erfindung der zur Vorkammer konzentrische Ringspalt in der Nähe der betreffenden Stirninnenseite des Behälters mit einem ausreichenden radialen Abstand zur Mantelinnenseite der Vorkammer angeordnet, ergibt sich eine hochwirksame Durchmischung des in die Vorkammer eingeblasenen Medienstroms.If, according to a further embodiment of the invention, the annular gap concentric with the prechamber is arranged in the vicinity of the relevant front inside of the container with a sufficient radial distance from the jacket inside of the prechamber, this results in a highly effective mixing of the media stream blown into the prechamber.

In der Zeichnung ist ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung in einem Längsschnitt dargestellt:
Die Vorrichtung besteht im wesentlichen aus einem zylindrischen Behälter 1, der außenseitig mit einer wärme- und schalldämmenden Isolierung 2 versehen ist.
In the drawing, an embodiment of the device according to the invention is shown in a longitudinal section:
The device consists essentially of a cylindrical container 1, which is provided on the outside with a heat and sound insulation 2.

Der Behälter 1 ist in der Nähe einer Stirnseite 3 mit einem die Behälterwandung radial durchdringenden Eintrittsstutzen 4 versehen, der an die Saugseite eines konzentrisch auf der Stirnseite angeordneten Radialgebläses 5 angeschlossen ist. Ein Laufrad 6 des Radialgebläses 5 ist von einem Gehäuse 7 umgeben, das mit einem Ringspalt 8 versehen ist. Dieser mündet in eine Vorkammer 9, die sowohl mit der Eintrittsseite von in Mantelnähe des Behälters 1 zylinderförmig angeordneten Wärmetauscherrohren 10 wie auch mit der Eintrittsseite eines koaxialen Bypasses 11 in Verbindung steht.The container 1 is provided in the vicinity of an end face 3 with an inlet connection 4 which penetrates radially through the container wall and is connected to the suction side of a radial fan 5 arranged concentrically on the end face. An impeller 6 of the radial fan 5 is surrounded by a housing 7 which is provided with an annular gap 8. This opens into a prechamber 9, which is connected both to the inlet side of heat exchanger tubes 10, which are arranged cylindrically near the jacket of the container 1, and to the inlet side of a coaxial bypass 11.

Die Wärmetauscherrohre 10 erstrecken sich axial über den wesentlichsten Teil der Länge des Behälters 1 und münden in eine Ringkammer 12, die an eine Stirnseite 13 des Behälters 1 angrenzt. Die Ringkammer 12 umschließt einen Brenner 14, der konzentrisch auf der Stirnseite 13 angeordnet ist und in ein koaxiales Rauchgasmischrohr 15 mündet.The heat exchanger tubes 10 extend axially over the most essential part of the length of the container 1 and open into an annular chamber 12 which adjoins an end face 13 of the container 1. The annular chamber 12 encloses a burner 14, which is arranged concentrically on the end face 13 and opens into a coaxial flue gas mixing tube 15.

Der Austrittsquerschnitt des Rauchgasmischrohrs 15 liegt in einem axialen Abstand zu einer die Vorkammer 9 vom übrigen Teil des Behälters 1 abtrennenden Stirnwand 16. Dieser ist ein Zylinder 17 zugeordnet, der sich über den wesentlichsten Teil der Länge des Rauchgasmischrohrs 15 erstreckt und mit diesem eine Hauptbrennkammer 18 definiert, die in der Nähe des Eintrittsquerschnitts des Rauchgasmischrohrs 15 mit einem Ringraum 19 verbunden ist, welcher die Wärmetauscherrohre 10 enthält. Am Ringraum 19 ist, dem Eintrittsstutzen 4 benachbart, ein Austrittsstutzen 20 angeschlossen.The outlet cross section of the flue gas mixing tube 15 lies at an axial distance from an end wall 16 which separates the antechamber 9 from the remaining part of the container 1. This is assigned a cylinder 17 which extends over the most essential part of the length of the flue gas mixing tube 15 and with it one Main combustion chamber 18 is defined, which is connected in the vicinity of the inlet cross section of the flue gas mixing tube 15 with an annular space 19 which contains the heat exchanger tubes 10. An outlet connection 20 is connected to the annular space 19, adjacent to the inlet connection 4.

Der Bypass 11 ist mit einer Klappe 21 ausgerüstet, mit der sich der über das Radialgebläse 5 in die Vorkammer 9 geförderte Medienstrom zu einem mehr oder weniger großen Teil über den Bypass 11 unter Umgehung der Wärmetauscherrohre 10, der Ringkammer 12 und des Brenners 14 unmittelbar dem aus dem Rauchgasmischrohr 15 austretenden und insoweit bereits vorbehandelten Medienstrom beimischen läßt. Dazu besteht der Bypass 11 aus einem Stutzen 22, der mit radialen Durchbrüchen 23 versehen und stirnseitig verschlossen ist.The bypass 11 is equipped with a flap 21, with which the media flow conveyed via the radial fan 5 into the prechamber 9 is, to a greater or lesser extent, via the bypass 11 bypassing the heat exchanger tubes 10, the annular chamber 12 and the burner 14 Leaving from the flue gas mixing tube 15 and so far already pre-treated media stream can be mixed. For this purpose, the bypass 11 consists of a nozzle 22 which is provided with radial openings 23 and is closed on the end face.
