Description

Axialverdichter mit verdrehbaren Leitschaufeln für staubhaltiges Gas Die Erfindung betrifft Axialverdichter für staubhaltiges Gas mit verdrehbaren Leitschaufeln.Axial compressor with rotatable guide vanes for dusty gas The invention relates to axial compressors for dust-containing gas with rotatable guide vanes.

Bei diesen pflegt Staub aus dem Förderstrom in die Spalte zwischen den Leitschaufel-Drehzapfen und den Zapfenlagern im Leitschaufelträger zu dringen und die Zapfen und ihre Lager zu verschmutzen und zu verschleißen.With these, dust from the conveying flow takes care of the gap between penetrate the vane pivot and journal bearings in the vane carrier and dirty and wear out the journals and their bearings.

Die Erfindung beruht auf dem Gedanken, das Eindringen des Staubes in die Drehzapfenlager durch Sperrgas zu verhindern. Sie sieht, damit nicht zu jedem einzelnen Zapfenlager eine besondere Sperrgasleitung geführt zu werden braucht, vor, daß die Leitschaufel-Verstellvorrichtung nebst den Antriebsenden der Drehzapfen in einem den Leitschaufelträger umgebenden geschlossenen Raum angeordnet ist; solcher Raum ist zum Schutze gegen Beschädigung und Verschmutzung von außen an sich bekannt. Sie sieht ferner vor, als Sperrgas das Fördergas selbst zu verwenden, und zwar staubfrei gefiltertes Fördergas; dieses Sperrgas muß natürlich höheren als den im Förderweg an den Leitschaufeln herrschenden Druck haben. Durch diese Kombination wird der bauliche Aufwand recht gering.The invention is based on the idea of the penetration of dust to prevent the trunnion bearings from being caused by sealing gas. She sees so, not to everyone a special sealing gas line needs to be routed to individual journal bearings, suggest that the vane adjustment device along with the drive ends of the trunnions is arranged in a closed space surrounding the guide vane carrier; such Space is known per se for protection against damage and contamination from the outside. It also provides for the conveying gas itself to be used as the sealing gas, and in fact dust-free filtered conveying gas; this sealing gas must of course be higher than that in the conveying path have pressure on the guide vanes. This combination makes the construction effort quite low.

Die Zeichnung zeigt einen erfindungsgemäßen Verdichter. Darin bedeutet 1 den Läufer, 2 die Laufschaufeln, 3 den Leitschaufelträger (zugleich Gehäuse), 4 den Einlaßkanal für das Fördermittel, 5 die Leitschaufeln, 6 die Verstellvorrichtung, 7 einen Mantel, der den Leitschaufelträger umgibt und einen geschlossenen Raum 8 bildet, 9 Zwischenwände, die den Raum in Teile von verschieden hohem Druck teilen, 10 den Förderweg, 11 die Sperrgasleitung, 12 einen Filter, 13 Zweige der Sperrgasleitung und 14 Drosselblenden, welche die gewünschten Drücke einstellen.The drawing shows a compressor according to the invention. In it means 1 the rotor, 2 the rotor blades, 3 the guide vane carrier (also housing), 4 the inlet channel for the conveyor, 5 the guide vanes, 6 the adjustment device, 7 a jacket which surrounds the guide vane carrier and a closed space 8 forms, 9 partitions that divide the room into parts of different pressure, 10 the conveying path, 11 the sealing gas line, 12 a filter, 13 branches of the sealing gas line and 14 throttle orifices, which set the desired pressures.
