The invention relates to a claw-shaped wave crest spoiler for an alternating lobe spray pipe. The claw-shaped wave crest spoiler smoothly extends out of the wave crest of the alternating lobe spray pipe, the length of the starting edge of the claw-shaped wave crest spoiler is smaller than that of the edge of the wave crest, the middle points of the starting edge and the edge of the wave crest coincide, and the straight line connecting the middle point of the starting edge of the claw-shaped wave crest spoiler and the ending sharp point of the claw-shaped wave crest spoiler points to the axis of the spray pipe; and then, a long-strip-shaped reinforcing rib is axially arranged from the middle point of the wave crest to the outside in the radial direction from the joint of the claw-shaped wave crest spoiler and the wave crest to the front and back, and the two ends of the reinforcing rib are gradually pointed and end at the outer wall face of the lobe spray pipe. The claw-shaped wave crest spoiler has the advantages that the mixing performance of the alternating lobe spray pipe with the claw-shaped wave crest spoiler is good, the temperature of airflow near the inner wall face of a mixing pipe is low, the aerodynamic shape change of the lobe spray pipe is small, and the service life is long.
本发明涉及一种用于交变波瓣喷管的爪型波峰扰流片,在交变波瓣喷管的波峰处圆滑延伸出呈爪型的波峰扰流片,爪型波峰扰流片起始边长度小于波峰边缘长度,两者中点重合,爪型波峰扰流片起始边中点与爪型波峰扰流片收尾尖点所连直线指向喷管轴线;然后由波峰中点径向向外,从爪型波峰扰流片和波峰连接处往前、往后轴向布置长条形加强筋,加强筋两头逐渐变尖终止于波瓣喷管外壁面。本发明的优点和取得的有益效果为:带爪型波峰扰流片的交变波瓣喷管掺混性能好,混合管内壁面附近气流温度低,波瓣喷管气动外形变化小,使用寿命高。
