Abstract
Stirred tank reactor is one of the three typical chemical machinery equipments and widely used in petroleum, chemical, pharmaceutical and other industrial fields .It is the basis of understanding the flow of fluid in stirred tank for optimizing design of reactor. This paper aims at the process of suspension polymerization of polyvinyl chloride (PVC) which is an important raw material of chemical production, and uses conventional design method to design the PVC stirred tank of 50m3 from the structure design. According to the fluid dynamics theory, standard K-E turbulent calculation model is established under the function of impeller, the corresponding boundary conditions are listed, and the grid is carried out successfully. And finally the FLOTRAN CFD software is used to simulate the complex flow field and flow pattern according to the multiple reference frame method.
