Beschreibung
Zusammenfassung:	The present invention relates to an impeller capable of extending service life and increasing desulfurization efficiency to reduce desulfurization time by improving the shape of a blade made of refractory, thereby increasing productivity. The impeller comprises a shaft; and a plurality of blades integrally formed on a lower part of the shaft. The blade includes a flat upper surface; a curved lower surface which is convexly formed downward; and an operating surface and a non-operating surface connecting the sides of the upper and lower surfaces and the other sides of the upper and lower surfaces. The operating surface and the non-operating surface include first straight parts and second straight parts straightly extended downward from one side and the other side of the upper surface; and a first curved part and a second curved part smoothly connecting the extending ends of the first straight part and the second straight part with a lower surface.
