摘　　要：根据紊流水动力特征研究絮凝动力学问题,分析絮凝的动力因素:涡旋运动产生的剪切力和离心惯性力是絮凝颗粒产生接触碰撞的主要作用力,而涡旋剪切力是絮凝反应的主导动力,根据此观点,设计出新型自激振荡管道式絮凝器,利用自激振荡原理产生有利于微絮体生成的水力条件,使絮凝效率得到提高。In this paper, the research on kinetics mechanism of flocculation is summarized based on the character of turbulent flow. The cut force and the centrifugal force brought by vortex are the main force to the collision in the flocculated grain ,and the former is primary. Based on this idea, the new type of self- excited oscillation pipeline flocculator had been designed.
