Studies On Mixing Performance Of The Servo Dynamic Mixer

Though promoting the human progress, the industrial development has been based on the excessive energy consumption and environmental disruption for a long time, which is more and more outstanding and becomes the critical factor of restricting human survival and progress. So what is the most important is to build a industrial model of energy saving and environmentally friendly. Mixing operation, which has a direct effect on the whole production process and the final product quality and is closely bound up with energy saving and environmental protection, is one of the most universal and most important working procedures in the modern industry. So it is very significant to research and develop more efficient mixing technology and mixing facility.Common mixing technology and mixing facility were introduced, especially the classification, the operating principle, the research status of the static mixer which had some common points with the technique studied in this paper. Based on the above research, the structure features and the working principle of the servo dynamic mixer were introduced. Combining the method of visualization experiment and numerical simulation, the mixing mechanism of the servo dynamic mixer applied in distributed mixing and dispersive mixing were studied respectively. What is more, the evaluation methodology of the mixing effect aimed at different mixing type was set up.On the basis of the mixing mechanism obtained and the structure and compound mode of the rotors which were the critical component in the servo dynamic mixer, the structure and the compound mode of the rotors were improved. Then visualization experiment and numerical simulation were conducted to study the mixing performance of rotors with opposite helical direction arranged crosswise and T-shaped helical blade rotors applied in distributed mixing and baffling-disturbed combined rotors and opposite-helix direction combined rotors applied in dispersive mixing. The results showed that the mixing performance of the rotors with the structure and compound mode improved was better than the rotors before.
