| titleOfInvention | Polyphenylene sulfide production solvent recovery unit |
| abstract | The utility model discloses a polyphenylene sulfide production solvent recovery device, belonging to the technical field of polyphenylene sulfide production; the device comprises a separation tank, a first rectifying tower and a second rectifying tower, wherein a stirring device is arranged in the separation tank, a liquid outlet is formed in the top of the separation tank, one end of a liquid guide pipe extends into the separation tank, and the other end of the liquid guide pipe is connected with the liquid inlet of the first rectifying tower through a pipeline; a concentrated liquid outlet at the bottom of the first rectifying tower is connected with the first rectifying tower through a first axial flow circulating pump, the concentrated liquid outlet is connected with a centrifugal machine through a second pipeline, a liquid phase outlet of the centrifugal machine is connected with a liquid inlet at the top of the second rectifying tower, a discharge port at the bottom of the second rectifying tower is connected with the second rectifying tower through a third pipeline, and a second axial flow circulating pump is arranged on the third pipeline; solves the problem that the distillation column is blocked due to impurities in the mixed solution containing the NMP solvent. |
