搅拌桨性能对比试验研究

Comparative Experimental Study on Performance of Agitator

根据高黏度流体反应的工艺特点,开发了一种新型组合搅拌桨。研究了其混合性能,与传统的推进桨、涡轮式搅拌桨、斜叶桨进行了对比,并对内外桨转速最佳匹比进行试验研究。结果表明,在1.5%WTCMC羧甲基纤维素水溶液中,组合桨的较传统桨型具有混合时间短,物料混合均匀且省搅拌功率等优势;内外桨搅拌存在一个最佳的转速匹比。

To the special requirements of High viscosity fluid Chemical Industry,a kind of new type co-axial combined impeller was presented.Experimental investigation on mixing property of the impeller were performed,compared with the traditional impeller,the result shows that mixing time is short,the materials are mixed evenly and the stirring power is saved;there is an optimal speed ratio between the inner and outer impellers.
