中文摘要：

混合与许多化工过程密切相关，为了克服传统的搅拌混合装置或结晶器的缺点，运用薄膜振动混合的理念，开发出一种新型的混合装置／结晶器。其具有低剪切应力无搅拌混合和达到固体颗粒的均匀悬浮。在完成新型混合装置的冷模设计加工后，测定了它的流型；并用脱色法测定了甘油与水调配出不同中高粘度的流体的混合时间；通过测定不同振动频率下的混合时间的变化，绘制出混合时间变化曲线，从而可确定最佳的操作条件；通过加入不同密度的固体颗粒，模拟结晶过程的固体相悬浮状况。这种新型混合装置具有较高的实用价值，市场前景广阔。

英文摘要：

Due to the importance of mixing to crystallization and reaction processes, a novel mixing device/ crystallizer has been developed using a membrane vibration element,which aims to overcome the disadvantages of traditional agitation mixing from studying new mixing technology. It can achieve lowest shear stress and the maximum uniformity for solid suspension without any internal agitator. After designing and fabricating the mixer, the flow pattern is studied by a direct visual technique and measured mixing times of fluids at different middle-high viscosity using a decolorized method. By changing the vibration frequencies we found the optimal operation conditions in terms of mixing time. At the same time, in order to simulate crystallization process behaviors of solid suspension in the mixer is also studied by putting various density particles. This novel mixer can be widely used in many processes with great commercial and market potential.
