Description

Technical Field

[0001] This utility model relates to the technical field of polyethylene glycol production equipment, specifically to a post-processing device suitable for continuous polymerization reactions of polyethylene glycol. Background Technology

[0002] Polyethylene glycol (PEG) has a wide range of applications in many fields. For example, in the pharmaceutical field, its good biocompatibility makes it a common drug carrier. In the cosmetics industry, it can be used to improve the texture and moisturizing properties of products. As the applications of PEG continue to expand, the requirements for its production efficiency and quality are also increasing. After the continuous polymerization reaction of PEG, a series of post-processing operations are required to meet the needs of different fields.

[0003] Currently, traditional post-processing equipment has many drawbacks. On the one hand, some equipment has low separation efficiency, making it difficult to completely separate polyethylene glycol from impurities and byproducts in the reaction process, resulting in low product purity and affecting its application in high-end fields. On the other hand, the automation level of existing equipment is generally insufficient, and many operations require manual intervention. This not only increases labor intensity and production costs, but also easily leads to unstable product quality due to differences in human operation, making it difficult to meet the requirements of large-scale, high-quality production. At the same time, some equipment is not rational in energy utilization, resulting in energy waste, which is not in line with the current production concept of energy conservation and environmental protection.

The material after preliminary separation enters the adsorption column 7 of the impurity adsorption mechanism, where organic impurities, pigments, and ionic impurities are removed under the action of multiple adsorption layers 8. The adsorbed and purified material enters the distillation column 12 of the high-efficiency distillation mechanism, where distillation separation is carried out under precisely controlled temperature and pressure. The heat pump 15 recovers the waste heat from distillation for heating.
