液相混合时间是搅拌过程的重要内容。在釜径３８６ｍｍ的搅拌釜内，采用热电偶温差法考察了搅拌桨型、挡板、气体分布器等结构因素和转速、气量、颗粒分率等操作因素对自浮颗粒三相搅拌混合的液相混合时间的影响。实验发现，轴向流动是决定液相混合时间的最重要因素，下层桨与釜底的距离以０．３Ｄ为宜，ＢＧＢＧ挡板最优，环径为０．８Ｄ的分布环最佳。 对４５ＳＰＵ＋４５ＳＰＤ＋ＤＴ配ＡＡＡＡ或ＡＢＡＢ挡板，大、中气体分布环，得到混合时间关联式为：对４５ＳＰＵ＋４５ＳＰＤ＋ＷＴ配ＡＡＡＡ或ＡＢＡＢ挡板，大、中气体分布环，得到混合时间关联式为：
Liquid mixing time is an important part of the mixing process. In the 386mm reactor, the thermocouple temperature difference method was used to investigate the effect of structural factors such as stirring paddle, baffle, gas distributor and other operating factors such as rotational speed, gas volume and particle fraction on the three-phase mixing and stirring of self-floating particles The impact of mixing time. The experimental results show that the axial flow is the most important factor that determines the liquid mixing time. The distance between the lower paddle and the bottom of the tank is 0.3D, the best is the BGBG baffle, and the ring with a diameter of 0.8D is the best. For 45SPU + 45SPD + DT with AAAA or ABAB baffle, large and medium gas distribution rings, the mixing time is obtained as follows: For 45SPU + 45SPD + WT with AAAA or ABAB baffle, large and medium gas distribution rings, the mixing time is obtained as:
