The invention discloses an anti-wear ash conveying pipeline bend structure. The technical problem that an ash conveying pipeline bend pipe fitting is likely to be worn out is solve. The anti-wear ash conveying pipeline bend structure comprises an ash conveying front straight pipe (1) and an ash conveying rear straight pipe (2), a hollow ball bend pipe fitting (3) is connected between the ash conveying front straight pipe (1) and the ash conveying rear straight pipe (2), the ratio of the diameter of an inner cavity of the hollow ball bend pipe fitting (3) to the inner diameter of the ash conveying front straight pipe (1) is 2-3, and the included angle between the ash conveying front straight pipe (1) and the ash conveying rear straight pipe (2) is 100-120 degrees. By means of a dynamic anti-wear layer formed by a dust attaching sedimentation layer formed by dust in the inner cavity of the hollow ball bend pipe fitting, the corner of an ash conveying pipeline is not likely to be worn.
