Description

Schnelldampferzeuger, Dampfüberhitzer u. dgl. Der Erfindungsgegenstand betrifft einen Schnelldampferzeuger, Dampfüberhitzer u. dgl., in denen der Dampf durch abwechselnd rechts-und linksgängige Leitvorrichtungen eine entsprechende Drallbewegung erhält. Bei diesen Vorrichtungen soll der im Dampfstrahl vorhandene Kesselsteinstaub gezwungen sein, sich an bestimmten, leicht zugänglichen Stellen abzulagern, ohne daß dadurch der wärmetechnische Wirkungsgrad der Vorrichtung irgendwie beeinträchtigt wird. Zu diesem Zweck sind die genannten Leitvorrichtungen in besonderen Dampfleit- und Umlaufkammern, die aus Leitbögen und Umlaufkammern bestehen, derart eingebaut, däß hierdurch der freie Querschnitt der Heizkörper nicht verringert wird.Rapid steam generator, steam superheater and the like relates to a rapid steam generator, steam superheater and the like, in which the steam alternating right and left hand guiding devices create a corresponding twisting motion receives. With these devices, the scale dust present in the steam jet should be forced to deposit in certain easily accessible places without that thereby the thermal efficiency of the device somehow impaired will. For this purpose, the mentioned guiding devices are in special steam guiding and circulation chambers, which consist of guide arcs and circulation chambers, installed in such a way that that this does not reduce the free cross-section of the radiator.

Die Zeichnung veranschaulicht eine beispielsweise Ausführung des Erfindungsgegenstandes und zeigt in Abb. i eine Ansicht, Abb. 2, 3, 4. Einzelheiten derselben.The drawing illustrates an example of an embodiment of the subject matter of the invention and shows in Fig. i a view, Fig. 2, 3, 4. Details of the same.

Der in der Abb. i dargestellte Schnelldampferzeuger besteht aus einzeln übereinander angeordneten Verdampf errohren b, k, u, die entsprechend ihrer Anordnung untereinander durch Dampfleit- und Umlaufkammern d und mit einem Dampfsammler c zu einem Verdampferelement a verbunden sind. Zur Speisung des Verdampfers a dient ein Zuführungsrohr a mit einer Einspritzvorrichtung f. Die in die unterste Ver.dampferstrecke b eingebaute Einspritzvorrichtung führt dem Verdampfer das Speisewasser unter Druck in fein zerstäubtem Zustand zu, etwa in Form von Nebel. Dieser Nebel gelangt nach Abb.2 durch den Leitbogen g in die Kammer h der Leit- und Umlaufkammer d nach Durchströmung der Leitvorrichtung in das darüber angeordnete Verdampferrohr u und, nachdem er alle V erdampferstrecken k-u durcheilt hat, in den Dampfsammler c. !ist nach Abb. 3 die mit rechtsgängigen Leitrippen L, m nach Abb. 4. die mit linksgängigen Leitrippen o ausgestattete Leitvorrichtung. Die Kammern d enthalten nach Abb. 2 einen Konus p, in dem die entsprechend geformten Leitvorrichtungen ruhen. Diese besitzen einen zylindrischen Schaft g, der in einer Bohrung t der Verschlußschraube r geführt und gelagert ist. Eine Spiralfeder s ermöglicht die einfache und leichte Einführung der Leitvorrichtungen in den Konus.The high-speed steam generator shown in Fig. I consists of individually stacked evaporator tubes b, k, u, which, according to their arrangement, are connected to one another by steam guide and circulation chambers d and with a steam collector c to form an evaporator element a. A feed pipe a with an injection device f is used to feed the evaporator a. The injection device built into the lowest evaporator section b supplies the evaporator with the feed water under pressure in a finely atomized state, for example in the form of mist. As shown in Fig. 2, this mist passes through the guide bend g into the chamber h of the guide and circulation chamber d after flowing through the guide device into the evaporator pipe u arranged above and, after it has rushed through all the evaporator sections ku, into the steam collector c. ! is according to Fig. 3 the guide device with right-hand guide ribs L, m according to Fig. 4. the guide device equipped with left-hand guide ribs o. According to Fig. 2, the chambers d contain a cone p in which the correspondingly shaped guide devices rest. These have a cylindrical shaft g which is guided and supported in a bore t of the screw plug r. A spiral spring s enables the guide devices to be introduced into the cone in a simple and easy manner.

An den glatten Rohrwandungen der beschriebenen Vorrichtung kann sich Kesselstein wegen der hohen Dampfgeschwindigkeit nicht ansetzen, jedoch muß dieser zur Verhütung von Schäden aus dem Dampf ausgeschieden sein. Nun aber treten bei der Umkehrung der Drallbewegung des Dampfstrahles in diesem an den Orten der Umkehrvorrichtungen große Zentrifugalkräfte auf, welche die schweren Teile, also Nebeltropfen und Kesselsteinstaub, herausschleudern und zur Sammlung in den sogenannten toten Räumen der Umkehrvorrichtungen -- den durch das Aneinanderstoßen von Leitrippen und Konuswand entstehenden Ecken - bringen. Hierbei feuchten die Nebeltropfen den Kesselsteinstaub an und erleichtern dadurch dessen Festhaften. Eine Schlammbildung ist dabei ausgeschlossen, weil das Wasser durch die Hitze der Konuswand verdampft wird.On the smooth pipe walls of the device described can No scale build-up due to the high steam speed, but it must to prevent damage from being eliminated from the steam. But now join the reversal of the swirling movement of the steam jet in this at the locations of the reversing devices large centrifugal forces, which the heavy parts, i.e. mist droplets and scale dust, hurled out and collected in the so-called dead rooms of the reversing devices - the corners created by the contact between the guide ribs and the cone wall - bring. The mist droplets moisten the scale dust and make it easier thereby its adherence. Sludge formation is excluded because that Water is evaporated by the heat of the cone wall.
