| titleOfInvention | Pyridine recovery system for diosmin production |
| abstract | The utility model discloses a pyridine recovery system for in diosmin production belongs to solvent recovery technical field in the diosmin production. The device comprises an online water separator, wherein the online water separator comprises a first condensing unit arranged at the upper part and a packing layer arranged at the middle lower part; the first condensing unit is connected with a second condensing unit through a condensing pipe, and the second condensing unit is connected with a pyridine collecting tank; the front side of a station of the pyridine collection tank is provided with a pyridine recovery workshop, the pyridine recovery workshop comprises an extraction tank and a rectifying tower, and the extraction tank is arranged on the rear side of the station of the rectifying tower; the reaction kettle is connected with a pyridine collecting tank. The method realizes the recovery of the pyridine separated from water in the steam in the reaction system for on-line production and the recovery of the pyridine with water after the reaction system is finished, ensures the recovery rate of the pyridine to be more than 98.5 percent, and simultaneously ensures the conversion rate of the reaction system for producing diosmin. |
