Abstract
Description
Betrifft: Apparat zur Durchführung thermischer Prozesse Die ilerstellung und Benutzung von meist horizontal an(teordneten indirekt beheizten, rotierenden meist Trommel artigen Gefäße, beispielsweise zur Pvrolyse orqaniscller Stoffe, die in der Regel aus verfahrenstechnischen (,ründen in sich hermetisch abgeschlossen oder abgedichtet sein müssen, ist bekannt und technisch im Gebrauch.-Die Schwierigkeiten der existierenden Konzeptionen bzw.Subject: Apparatus for carrying out thermal processes and use of mostly horizontally arranged (indirectly heated, rotating mostly drum-like vessels, for example for pvrolysis orqaniscller substances, the usually from procedural (, are hermetically sealed or must be sealed is known and technically in use.-The difficulties the existing concepts or
bisher gefundenen technischen Aufbaukonstruktionen dieser Systeme liegen beispielsweise bei Pyrolysetrommel, insbesondere hinsichtlich des Trommel-Innenraums in der Abdichtung gegenüber der äußeren Heizzone und der Umwelt und in der Lagerung der Trommel, die in der Regel in ihren Dimensionen Mindestlängen von 3 m und tindestdurchmesser von 0,5 m überschrgiten und somit bei Betriebstemperaturen zwischen 350 C und 10000C erheblichen Längenänderungen unterworfen sind (Wärmedehnung), während das Außengehäuse isoliert gegen Wärmeverlust nach augen in der Regel keinen oder nur unwesentlichen Dimensionsänderungen unterworfen ist.previously found technical structures of these systems lie, for example, in the case of the pyrolysis drum, in particular with regard to the interior of the drum in sealing against the outer heating zone and the environment and in storage the drum, which usually has a minimum length of 3 m and a minimum diameter by 0.5 m and thus at operating temperatures between 350 C and 10000C are subject to considerable changes in length (thermal expansion), while the outer housing generally no or only insignificant insulation against heat loss to the eyes Is subject to dimensional changes.
Die Erfindung bezieht sich auf einen Apparat gemäß den im nachfolgenden aufgezeiqten Ansprüchen, die diese Schwierigkeiten beseitigt, und zwar dadurch, daß nur ein Teil, beispielsweise die mittlere Sektion des Trommelgehäuses (Außenmantel) stationär befestigt oder gelagert ist. Die hinteren und vorderen Begrenzungsschilde oder Flansche sind so ausgeführt und angebracht, daß sie über Dehnungs- und/oder Federelemente die Längenänderung, die bei der Erwärmung der Drehtrommel auftritt, ausgleichen und gleichzeitig die Lagerstutzen oder Zapfen der Innentrommel so aufnehmen können, daß die radiale Dehnung bzw.The invention relates to an apparatus according to the following listed claims, which overcomes these difficulties by, that only a part, for example the middle section of the drum housing (outer jacket) is fixed or stored in a stationary manner. The rear and front boundary shields or flanges are designed and attached so that they have expansion and / or Spring elements the change in length that occurs when the rotating drum is heated, equalize and at the same time accommodate the bearing studs or journals of the inner drum can that the radial expansion resp.
Dimensionsänderung und auch die über die Trommellänge auftretenden Verschiebungen axialer Art absorbiert werden.Dimensional changes and also those occurring over the length of the drum Axial displacements are absorbed.
Desweiteren sind im Bereich des Trommeleingangs und des Materialaustritts an den Lagerstellen im Heizraum Aufhängungen angeordnet oder skelettartige Gerippe vorgesehen, an denen das über die gesamte Länge der Trommel verlaufende Stützrollensystem oder die Stützwelle(n) befestigt sind, so daß mit steigender Temperatur und damit wachsendem Durchmesser der Trommel durch die in der Aufhängung ebenfalls auftretende mehr oder minder linear verlaufenden Längenänderungen die für die axiale Laufqleichheit der Trommel notwendige Führungs- und Auf lagerungsdimensionen eingehalten oder weitgehend sichergestellt werden.Furthermore are in the area of the drum entrance and the material exit Suspensions or skeletal frameworks are arranged at the bearing points in the boiler room provided on which the support roller system running over the entire length of the drum or the support shaft (s) are attached so that with increasing temperature and thus increasing diameter of the drum due to that which also occurs in the suspension more or less linear changes in length that are responsible for the axial equilibrium the drum necessary leadership and storage dimensions are complied with or largely be ensured.
