Reaction Crystallizer
Structure of PMG Reaction Crystallizer
● Composed of two concentric inner and outer cylinders.
● The inner cylinder rotates at high speed, driving the reaction liquid to form alternating and orderly arranged fluid vortices, achieving thorough and regular mixing.
Structural Features
High Mixing Efficiency
● Minimal axial backmixing, high reaction driving force.
● Vortex columns provide a large specific surface area for the reaction medium.
● High mass transfer coefficient combined with low shear force.
Stirring and Fluidization Capabilities
● Gentle yet effective stirring to enhance gas-liquid mixing.
● Maintains uniform fluidization of solid catalyst particles; even at low axial flow rates, optimal fluidization is achieved by adjusting the inner cylinder speed.
