| Abstract: | Key points in the design for the process of freezing crystallization were discussed by analyzing influencing factors. The relationships between the degree of super-saturation in the process of sodium sulfate docahydrate crystallization temperature were analyzed. Method that through controlling circulation rate of mother liquid to control the super-saturation so as to avoid primary nucleation was studied. Internal structure of chiller-crystallizer was improved so that crystal nucleus could mix with super-saturation solution completely and finally achieve the purpose of promoting growth of crystal. Meanwhile fine crystal discharge device was added to increase crystal growth rate so as to reach the aim of improving crystalline quality. |
