Recovery device for diluent waste liquid containing PGMEA

The utility model discloses a PGMEA-containing diluent waste liquid recovery device which is characterized by comprising a kettle bottom liquid preliminary recovery system, a kettle bottom liquid terminal recovery system, a light component removal system and a finished product system which are communicated in sequence. According to the PGMEA-containing diluent waste liquid recycling device, bottom liquid reduction and solvent recycling of the PGMEA-containing diluent waste liquid can be achieved to the maximum extent, the problem that the production efficiency is reduced due to the fact that the coking frequency of the tube bundle of the rectifying kettle is frequent in the PGMEA rectification resource utilization process is solved, the effect of shortening the tube bundle cleaning frequency is good, and the PGMEA-containing diluent waste liquid recycling device has high environment-friendly and economic value. 本实用新型公开了一种含PGMEA的稀释剂废液回收装置，其特征在于，包括：依次连通的釜底液初步回收系统、釜底液终端回收系统、脱轻系统、以及成品系统。本实用新型可实现含PGMEA的稀释剂废液最大程度釜底
