Description
Gekühlte Rauchgasklappe Die Erfindung bezieht sich auf eine gekühlte Rauchgasklappe, die als von einem Kühlmedium durchflossener Hohlkörper ausgebildet ist, der durch Trennwände in mehrere in Richtung der Drehachse nebeneinanderliegende Kammern unterteilt ist. Bei den bekannten Rauchgasklappen dieser Art durchfließt das Kühlmedium nacheinander sämtliche nebeneinanderliegende Kammern. DieseArt derKühlung hat den Nachteil, daß im Betrieb die Temperatur der Rauchgasklappe an dem einen Ende der Drehachse wesentlich größer ist als an dem anderen Ende. Dadurch ergeben sich Temperaturspannungen und ein Verziehen der Klappe.Cooled flue gas damper The invention relates to a cooled one Flue gas flap designed as a hollow body through which a cooling medium flows is, which by partition walls in several adjacent in the direction of the axis of rotation Chambers is divided. In the known flue gas flaps of this type flows through the cooling medium one after the other all adjacent chambers. This type of cooling has the disadvantage that the temperature of the flue gas flap on the one during operation End of the axis of rotation is much larger than at the other end. Result from this temperature stresses and distortion of the flap.
Erfindungsgemäß können diese Nachteile dadurch vermieden werden-, daß die Kammern so angeordnet sind, daß sie von dem Kühlmedium im Parallelstrom durchflossen werden. Es ergibt sich hierbei eine gleichmäßige Temperatur über die gesamte Klappenbreite, da das Kühlmedium in jede Kammer mit der gleichen Temperatur eintritt.According to the invention, these disadvantages can be avoided, that the chambers are arranged so that they are of the cooling medium in parallel flow are flowed through. This results in a uniform temperature over the entire flap width, since the cooling medium in each chamber is at the same temperature entry.
Um auch den Einfluß des Unterschiedes zwischen Eintrittstemperatur und Austrittstemperatur des Kühlmediums auf die Temperatur der Rauchgasklappe weitgehendst zu beseitigen, können in weiterer Ausbildung des Erfindungsgedankens die Zu-und Abflüsse der Kammern so angeordnet sein, daß bei zwei nebeneinanderliegenden Kammern die Strömungsrichtungen des Kühlmediums an den gleichen Rauchgasklappenseiten entgegengesetzt zueinander gerichtet sind.To also the influence of the difference between inlet temperature and outlet temperature of the cooling medium to the temperature of the flue gas flap as much as possible to eliminate, can in a further development of the inventive concept the supply and Outflows of the chambers can be arranged so that with two adjacent chambers the flow directions of the cooling medium on the same flue gas flap sides are opposite are directed towards each other.
Nach einem weiteren Erfindungsmerkmal kann die Züi- und Abführung des Kühh-nediums durch zwei die Drehachse bildende konzentrische Rohre erfolgen.According to a further feature of the invention, the supply and discharge of the cooling medium through two concentric tubes forming the axis of rotation.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. Es zeigt Fig. 1 eine erfindungsgemäße Rauchgasklappe in Ansicht, Fi-. 2 einen Querschnitt nach den Linien I-I der Fig. 1, Fig. 3 einen Querschnitt nach den Linien II-II der Fig. 1.An exemplary embodiment of the invention is shown schematically in the drawing. It shows Fig. 1 a flue gas flap according to the invention in view, Fi-. 2 shows a cross section according to the lines II in FIG. 1, FIG. 3 shows a cross section according to the lines II-II in FIG. 1.
Die Drehachse der Rauchgasklappe wird durch die beiden konzentrischen Rohre 1, 2 gebildet. Durch Querwände 3 sind die beiden als Hohlkörper ausgebildeten Klappenteile 4 in je acht Kammern unterteilt. In sämtlichen Kammern eines Klappenteiles 4 sind durch eine parallel zu den Wänden des Klappenteiles 4 liegende Längswand 5 zwei zusammenhängende Kanäle gebildet, von denen der eine an das Zuflußrohr 1 und der andere an das Abflußrohr 2 angeschlossen ist. Wie aus den Fig. 2 und 3 ersichtlich ist, liegt bei zwei nebeneinanderliegenden Kammern an der gleichen Seitenwand eines Klappenteiles immer ein Zuflußkanal 6 neben einem Abflußkanal 7. Das Kühlmedium tritt durch die beiden Zuleitungen 8 von beiden Seiten in das Zuflußrohr't ein. Von dort verteilt es sich über die Zuflußkanäle 6 der sechzehn Kammern der Rauchgasklappe und durchströmt diese im Parallelstrom. Durch die Abflußkanäle 7 gelangt das Kühlmedium dann in das Abflußrohr 2, das es an seinen beiden Enden durch die Ableitungen 9 verläßt. Je nach den Betriebse-fordernissen ist es auch möglich, nur eine Zuleitung und nur eine Ableitung vorzusehen, wobei diese an einem Ende oder auch an verschiedenen Enden der Drehachse liegen können.The axis of rotation of the flue gas flap is formed by the two concentric tubes 1, 2. The two flap parts 4, which are designed as hollow bodies, are each divided into eight chambers by transverse walls 3. In all the chambers of a flap part 4, a longitudinal wall 5 lying parallel to the walls of the flap part 4 forms two contiguous channels, one of which is connected to the inflow pipe 1 and the other to the outflow pipe 2. As can be seen from FIGS. 2 and 3 , with two adjacent chambers on the same side wall of a flap part there is always an inflow channel 6 next to an outflow channel 7. The cooling medium enters the inflow pipe through the two feed lines 8 from both sides. From there it is distributed over the inflow channels 6 of the sixteen chambers of the flue gas flap and flows through them in parallel flow. The cooling medium then passes through the drainage channels 7 into the drainage pipe 2, which it leaves at both ends through the discharge lines 9. Depending on the operating requirements, it is also possible to provide only one supply line and only one discharge line, whereby these can be at one end or at different ends of the axis of rotation.
