Embodiment 1
[0044] ⑴Add 5000L tap water to the sodium salt dissolving tank ①, raise the temperature to 65°C, add 2.8t ibuprofen sodium salt, and stir for 30 minutes.
[0045] ⑵Introduce the uniformly mixed ibuprofen sodium salt solution into the filter press ②, and filter through the filter screen, the insoluble matter is left on the filter screen of the filter press, and then discharged from the bottom; after the filtrate is absorbed by activated carbon, it enters the sodium salt solution Accept the tank ③ for temporary storage.
[0046] ⑶ The filtrate in the sodium salt solution receiving tank ③ is introduced into the primary condenser ⑦ through the feeding pump ④ and preheated to 85°C.
[0047] ⑷The preheated filtrate enters the stripping tower ⑤ from the top, the filtrate and steam exchange heat in the tower, the organic solvent is brought into the gas phase, and the filtrate from which organic matter is removed enters the stripping receiving tank ⑥ from the bottom of the stripping to...
