    摘要: The double reverse helix agitator with an internal conveying screw is used in a gas phase olefin polymerization reactor having at least one polymerization section and has helical flights defined by helical blades which are mounted to a shaft, which extend in opposite axial directions and which have approximately the same radius from the axis of rotation of the agitator. The shaft has a spiral screw thread thereon for conveying polymer particles axially by the agitator through a reactor vessel.
