| description | The utility model discloses a rectification separation device for 3-methylpyridine, and belongs to the technical field of preparation of 3-methylpyridine. In order to solve the problems that in the prior art, a rectification separation device is complex in structure, long in material moving distance, capable of influencing the heating effect and not beneficial to long-term work, the rectification separation device of the 3-methylpyridine comprises a rectification tank, a steam generator surrounds the outer portion of a heating bent pipe, and auxiliary heating rings are installed at the lower ends of an inclined pipe and a feeding pipe. A steam pipe is arranged outside the position between the steam generator and the auxiliary heating ring, an integrally-formed heat preservation frame is arranged outside the auxiliary heating ring, and a heat conduction strip plate is installed in the heat preservation frame. Steam can be conducted through the steam pipe outside the steam generator, auxiliary heating work is c |
