| titleOfInvention | A high-efficiency rectification device for succinic anhydride |
| abstract | The utility model discloses a high-efficiency rectification device for succinic anhydride, which comprises a rectification kettle, a rectification tower and a tower top condenser. A jacket is arranged on the outer wall of the bottom of the rectification kettle, and a steam inlet is arranged on the jacket. A central tube is arranged concentrically and vertically in the rectification kettle. The upper and lower ends of the central tube are respectively connected with an upper short tube and a lower short tube through a diameter reducing cone. , the top of the upper short pipe is provided with a gas collection box through the connecting rod, the lower end of the lower short pipe extends into the jacket, the driving device is installed under the rectification kettle, and the lower short pipe in the jacket is processed with a vent hole. Between the upper end of the upper short pipe and the gas collection box, between the lower short pipe and the bottom of the rectification kettle are movable sealing structures, and a circulation pipe is arranged between the steam outlet and the steam inlet, and a heater is arranged on the circulation pipe. The utility model has the advantages of reasonable structure, high heating efficiency, high heat utilization rate, and remarkable economic value and social value. |
