| titleOfInvention | 3-cyanopyridine rectification bed charge separation and recovery device |
| abstract | The utility model provides a device for separating and recovering 3-cyanopyridine distillation bottom materials, which comprises a negative pressure scraper film evaporator and a vacuum distillation tower; the first heat exchanger is connected with a feed inlet of the negative-pressure scraper film evaporator; the gas phase extraction outlet of the negative pressure scraper film evaporator is connected with the gas phase feed inlet of the vacuum rectifying tower; the crude 3-cyanopyridine liquid feed inlet is connected with the liquid feed inlet of the vacuum rectifying tower; a distillation bottom liquid extraction port of the negative-pressure scraper film evaporator is connected with a waste storage tank; the gas phase extraction outlet of the vacuum rectifying tower is connected with a second heat exchanger; the liquid extraction outlet of the vacuum rectifying tower is connected with a feed inlet of the heat exchanger; the two-liquid phase outlet of the heat exchanger is connected with the feed inlet of the reflux tank, the reflux extraction outlet of the reflux tank is connected with the feed pump, and the feed pump is connected with the reflux feed inlet of the vacuum rectifying tower; the bottom discharge extraction port of the reflux tank is connected with the feed inlet of the 3-cyanopyridine storage tank. The utility model can recover more than 80% of 3-cyanopyridine in the rectification bed charge, and the device has low energy consumption and can realize continuous and easy operation. |
