Description
Kreiselverdichter mit Vorrichtung zur Naßreinigung der Luft bei ihrem Durchgang. Es ist bekannt, staubhaltige Luft bei ihrem Durchgang durch ein- oder mehrstufige Kreiselverdichter, auch Ventilatoren, Exhaustoren, Turbogebläse genannt, durch Zusatz von Wasser vom anhaftenden Staub zu reinigen. Dabei sammelt sich ein erheblicher Teil des eingespritzten Wassers oder der sonst verwendeten Flüssigkeit sehr schnell auf den Schaufelflächen und wird infolgedessen nur ungenügend für die Reinigung herangezogen. Es ist deshalb bereits der Versuch gemacht, durch Einbau ruhender oder gegenläufiger Schlagstäbe das Wasser erneut zu zerstäuben und dem Luftstrom wieder zuzuführen, um eine bessere Wirkung und Ausnutzung des' Wassers zu erzielen. Diese Vorrichtungen weisen den Nachteil großen Kraftbedarfs und großen- Verschleißes auf. -Die vorliegende Erfindung erreicht den Zweck in einfacher Weise dadurch, daß die Schaufeln unterteilt und entgegen dem Sinne der Drehrichtung des Flügelrades kaskadenförmig versetzt werden. Es wird dadurch ein Abgleiten des bereits auf einem Schaufelflächenteil gesammelten Wassers am Ende dieses Stückes erreicht, welches somit erneut dem Luftstrom beigemischt wird. -Auf der Zeichnung ist schematisch ein Beispiel für die praktische Durchführung der Erfindung dargestellt. Man erkennt auf der linken Seite eines Gebläserades a die übliche alte Form der Flügel/, welche bekanntlich ganz geschlossen ist. Auf der rechten Seite dagegen ist der Flügel mehrfach unterteilt, so daß die kaskadenförmig abgesetzten Teile _ f', f" und f ` entstehen. Es ist ohne weiteres klar, daß zwischen diesen Teilen das auf den Schaufelflächen sich ansammelnde Wasser immer wieder dem Luftstrom beigemischt wird.Centrifugal compressor with a device for wet cleaning of the air as it passes through. It is known that dust-laden air can be cleaned of adhering dust by adding water as it passes through single-stage or multi-stage centrifugal compressors, also known as fans, exhaustors, turbo blowers. A considerable part of the injected water or the liquid otherwise used collects very quickly on the blade surfaces and is consequently only insufficiently used for cleaning. An attempt has therefore already been made to re-atomize the water by installing stationary or counter-rotating impact bars and to feed it back into the air flow in order to achieve a better effect and utilization of the water. These devices have the disadvantage of great power consumption and great wear. The present invention achieves the purpose in a simple manner in that the blades are divided and offset in a cascade against the direction of the direction of rotation of the impeller. As a result, the water that has already collected on a blade surface part slides off at the end of this section, which is thus mixed again with the air flow. -In the drawing, an example of the practical implementation of the invention is shown schematically. You can see on the left side of a fan wheel a the usual old shape of the blades /, which is known to be completely closed. On the right side, however, the wing is divided into plural form so that the cascading remote parts _ f ', f' and f 'are formed. It is readily apparent that the blade surfaces which collects water mixed with the air flow again between these parts will.
