China Agitation Equipment series crystal mixing equipment has now successfully designed and produced potash fertilizer crystal mixer of a production capacity of 150000 tons / year. This device has a function of reaction crystallization, crystallization separation, solid-liquid phase separation and synchronous operation of liquor circulation. It can effectively control the crystallization rate and fine crystal cutting, so that the output products are crystal particles. The device can realize continuous operation at room temperature.
The Issue of mixing efficiency in agitated tanks has drawn serious concern in many industrial processes. A sliding mesh(SM) approach is adopted to solve the rotation of the impeller. The simulated flow patterns and liquid velocities in the agitated tank are verified by experimental data in the literature. The simulation results indicate that the DES method can obtain more flow details than Reynolds-averaged Navier-Stokes(RANS) model. Local and global mixing time in the agitated tank is predicted by solving a tracer concentration scalar transport equation. The simulated results show that feeding points have great influence on mixing process and mixing time. Mixing efficiency is the highest for the feeding point at location of midway of the two impellers.
Two methods are used to determine global mixing time and get close result. Dimensionless global mixing time remains unchanged with increasing of impeller speed. Parallel, merging and diverging flow pattern form in the agitated tank, respectively, by changing the impeller spacing and clearance of lower impeller from the bottom of the tank. The global mixing time is the shortest for the merging flow, followed by diverging flow, and the longest for parallel flow. The research presents helpful references for design, optimization and scale-up of agitated tanks with multi-impeller.
