Description
Dampftrockner mit durch Schraubenflächen erzielter Abscheidung des Wassers Die Erfindung betrifft eine Verbesserung an Dampftrocknern und ähnlichen Abscheidern, bei welchen flüssige oder feste Partikel durch Flieh- oder Schleuderkraft von dein gasförmigen Strömungsmittel getrennt werden, und zwar besteht die Erfindung darin, daß einem Schraubenkörper von gleichförmiger Steigung der Abscheide- und Führungsgänge unmittelbar ein Leitkörper für das Strömungsmittel vorgeschaltet ist, dessen Leitschaufeln mit axial beginnender E,inlauffläche in allmählich zunehmender Steigung in die Richtung der Schraubengänge endigen.Steam dryer with deposition of the Water The invention relates to an improvement in steam dryers and the like Separators, in which liquid or solid particles by centrifugal or centrifugal force separated from the gaseous fluid, that is the invention in that a screw body of uniform pitch of the separation and A guide body for the fluid is connected directly upstream of the guide passages, its guide vanes with an axially beginning E, gradually increasing inlet surface End slope in the direction of the screw threads.
Feststehende Leitschrauben mit flachem Einlauf und steigendem Drall sind bekannt. Um eine genügende Anzahl Windungen unterzubringen, ist man gezwungen, diese Leitschrauben sehr lang zu bauen, was die Herstellung verteuert und für den Einbau hinderlich ist. Es wird dort nur in unvollkommenem Maße ein stoßfreier Einlauf des Strömungsmittels mit allmählicher Steigerung der Schleuderwirkung erzielt, wogegen man diesen gleichen Erfolg in wesentlich höherem Maße mit dem Erfindungsgegenstand erreichen kann, indem man bei zunehmendem Strömungsquerschnitt die Anzahl der Leitschaufeln vermehrt und zu einem besonderen Leitkörper zusammenfaßt, um das Strömungsmittel schichtweise zu erfassen und in kurzer Kurve in die Richtung der Schraubengänge abzulenken.Fixed guide screws with flat inlet and increasing twist are known. In order to accommodate a sufficient number of turns, one is forced to to build these guide screws very long, which makes the production more expensive and for the Installation is a hindrance. There is only an imperfectly smooth enema there of the fluid achieved with a gradual increase in the centrifugal effect, whereas one this same success to a much greater extent with the subject of the invention can be achieved by increasing the number of guide vanes as the flow cross-section increases increased and combined into a special guide body to the fluid to be grasped in layers and in a short curve in the direction of the screw threads distract.
Die Erfindung ist in einem Ausführungsbeispiel dargestellt. Das Gehäuse i des Abscheiders enthält die schraubenförmige Abscheiden orrichtung 2, der das Leitorgan 3 vorgelagert ist. Letzteres besteht aus einer Anzahl radial angeordneter Leitschaufeln, welche axial eine der Steigung der Abschleuderungsschraube entsprechende Krümmung erhalten und so dicht angeordnet werden, daß das Strömungsmittel diese Leitschaufeln beaufschlagen muß.The invention is illustrated in one embodiment. The case i of the separator contains the helical separator device 2, which Leitorgan 3 is upstream. The latter consists of a number of radially arranged Guide vanes, which axially correspond to the pitch of the throw-off screw Obtain curvature and be arranged so closely that the fluid this Must act on guide vanes.
Das einlaufende Strömungsmittel gelangt in eine um den Schraubengang gebildete Kammer, wo bereits eine Abscheidung von Verunreinigungen erfolgt, die an einem Zapfloch entleert werden. Die von der Leitschraube selbst abgeschiedenen Bestandteile gelangen in eine ringförmige Kammer am Grunde des Abscheiders, welche ebenfalls durch ein Zapfloch entleert werden können.The incoming fluid enters one around the screw thread formed chamber, where a separation of impurities already takes place can be emptied at a tap hole. Those separated from the lead screw itself Components get into an annular chamber at the bottom of the separator, which can also be emptied through a tap hole.
Die Erfindung läßt sich sowohl unabhängig von der Anordnung der Leitschraube als auch von der Anordnung des Ein- und Austrittes für das Strömungsmittel anwenden.The invention can be used both independently of the arrangement of the lead screw as well as the arrangement of the inlet and outlet for the fluid.
