Description
Vorrichtung zur Außenreinigung von Rippenrohren für Vorwärmer, Kondensatoren u. dgl. Es ist bekannt, zur Außenreinigung von Rohren Druckluft durch Rohre mit öffnungen gegen die zu reinigenden Außenflächen zu blasen. Diese Blasluftrohre sind gewöhnlich unabhängig von den zu reinigenden Rohren angeordnet.Device for external cleaning of finned tubes for preheaters, condensers It is known to use compressed air through pipes to clean the outside of pipes Blow openings against the external surfaces to be cleaned. These blown air tubes are usually arranged independently of the pipes to be cleaned.
Gemäß der Erfindung sind das oder die Blasrohre mit dem außen zu reinigenden, gerippten Vorwärmerrohr zu einem einheitlichen Stück vereinigt und parallel zur Rippenrohrachse angeordnet, bzw. bei schraubenförmigen Rippen in Richtung dieser Rippen geführt. Dadurch wird in der Hauptsache der Aufbau der Gesamtanordnung wesentlich vereinfacht und gleichzeitig eine erhöhte Festigkeit für das zu reinigende Rohr erzielt. Ferner wird die Wärmeübertragung begünstigt, da die für die Wärmeübertragung nutzbare Oberfläche vergrößert wird und die Heizgase mehr durcheinandergewixbelt oder abgelenkt werden.According to the invention, the blowpipe (s) with the outside to be cleaned, finned preheater tube combined into a single piece and parallel to the Arranged finned tube axis, or in the case of helical ribs in the direction of this Ribs led. As a result, the structure of the overall arrangement becomes essential in the main Simplified and at the same time increased strength for the pipe to be cleaned achieved. Furthermore, the heat transfer is favored, since the one responsible for the heat transfer usable surface is increased and the heating gases more tangled or get distracted.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt, und zwar zeigen Abb. t das Rippenrohr eines Vorwärmers mit zwei Blasrohren im Querschnitt und Abb. a in Längsansicht.The drawing shows an exemplary embodiment of the subject matter of the invention shown, namely Fig. t show the finned tube of a preheater with two blowpipes in cross section and Fig. a in longitudinal view.
Das Vorwärmerrohr a ist mit Rippen b versehen, auf deren Umfange zwei Blasrohre c sitzen, die zur Außenreinigung des Vorwärmerrohres dienen. Die beiden Blasrohre c liegen in Ausnehmungen der Rippen b und können in. letzteren eingegossen oder sonstwie befestigt oder eingesetzt sein. Die Austrittsöffnungen der Blasrohre c sind so angebracht, daß die aus diesen öffnungen austretenden Druckluftstrahlen zwischen den einzelnen Rohrrippen b gegen das Rohr a gerichtet sind, wodurch der zwischen den Rippen sich ablagernde Flugaschenstaub abgeblasen wird. Die Anzahl der Blasrohre c kann beliebig sein, d. h. es können anstatt zwei auch ein oder mehr als zwei Blasrohre vorgesehen sein. Ebenso können die Blasrohre anstatt parallel zur Längsachse des zu reinigenden Rohres a auch z. B. bei Verwendung schraubenförmiger Rohrrippen gleichfalls schraubenförmig entsprechend der Rippenführung um das Rohr herumlaufen.The preheater tube a is provided with ribs b, on the circumference of which sit two blower tubes c, which are used to clean the outside of the preheater tube. The two blowpipes c are located in recesses in the ribs b and can be cast into the latter or otherwise fastened or inserted. The outlet openings of the blower pipes c are arranged in such a way that the compressed air jets emerging from these openings are directed between the individual pipe ribs b against the pipe a, whereby the fly ash dust deposited between the ribs is blown off. The number of blowpipes c can be arbitrary, that is, instead of two, one or more than two blowpipes can also be provided. Likewise, the blowpipes can instead of parallel to the longitudinal axis of the pipe to be cleaned a also z. B. when using helical pipe ribs also run helically around the pipe in accordance with the rib guide.
Um die Blasvorrichtung in Betrieb zu setzen, braucht man nur das Blasrohr z. B. bei d an eine Druckluftleitung anzuschließen. Bei Verwendung mehrerer Blasrohre kann entweder jedes Rohr an eine Druckluftleitung angeschlossen oder es können die einzelnen Blasrohre unter sich auch durch Rohrstützen verbunden werden.To put the blower into operation, you only need the blowpipe z. B. to be connected to a compressed air line at d. When using several blowguns each pipe can either be connected to a compressed air line or the individual blowpipes can also be connected by pipe supports.
