Reconstruction of the Scraper Condenser Sealing System in the Final Polymerization Reactor
The causes of the shaft seal leakage accident in the scraper condenser of the polyester polymeriza-tion device were analyzed,and the problem of filamentous matter wrapped on the scraper of scraper con-denser in the process of polycondensation reaction was solved by optimizing the operating condition of scraper condenser and personnel operation process.After solving the problem of scraper winding,the shaft seal leakage problem caused by the bending of the drive shaft can be effectively avoided.Only the stable op-eration of the final condenser scraper condenser sealing system can ensure the stability of the vacuum sys-tem and the viscosity value of the polyester melt during the polymerization reaction,and avoid the environ-mental pollution and energy waste caused by the shaft seal leakage of the scraper condenser.
