roduct Introduction:
Vacuum ejector is the main equipment of the chemical fiber polyester vacuum system. The steam ejector is suitable for intermittent and continuous production of polyester and has been developed, and also has been matched with the polyester equipment of dozens of domestic and foreign enterprises, forming a complete model The series of steam ejectors.
Five-stage water vapor jet vacuum pump: working vacuum degree: 0.0133~0.067KPa·A

⑨Concentrated crystallization
Two-stage steam jet vacuum pump: working vacuum degree: 4~13KPa·A
Applications:
①Concentration and evaporation of compounds
②Vacuum concentration of inorganic salt and lye
③Desolubilization and dehydration of grease
④Phenyl anhydride, maleic anhydride, partial anhydride
In the polyester reaction of PTA, ethylene glycol medium is used as power to replace the steam jet pump to make the ethylene glycol medium recycled.
The ethylene glycol steam ejector is a new type of vacuum acquisition equipment developed to meet the high vacuum required for the polymerization of polyester chips. The power steam source of the ethylene glycol steam ejector is based on the heat source of the ethylene glycol steam generator as a high-temperature heat medium, and the power steam pressure is low. Use ethylene glycol as a cooling medium to cool them down, so as to achieve the closed loop use of ethylene glycol. It is a new type of energy-saving vacuum acquisition equipment.
