[0002] The use of graphite towers in chemical plants is increasing. Graphite towers are made of impermeable graphite, which has excellent corrosion resistance and temperature resistance. Graphite towers are mostly used in high-temperature and highly corrosive chemical industries. Graphite towers can be used for reactions, separations, synthesis, absorption, etc. in chemical industry. Due to the brittleness of graphite, in order to improve the compressive resistance, the existing graphite towers are assembled and connected by multiple graphite tower sections, and the surface of the graphite tower sections is provided with a metal shell.

[0003] Most existing graphite tower segment equipment sealing devices are too simple, the tower segment bonding part is in a "one" shape, and then a certain proportion of graphite cement is used for bonding. After a period of use, the graphite tower segment bonding part is prone to leakage due to the corrosion of temperature and chemical media, which brings great harm to chemical plants. Patent CN117244497A discloses a tower segment and a connection and fastening structure of a graphite tower, in which the outer grooves and inner grooves at the top and bottom of the two tower barrels are mutually sleeved, and the L-shaped groove opened at the bottom of the tower barrel is aligned with the clamping column installed at the top of the tower barrel, and the top tower barrel is rotated so that the clamping column is clamped into the L-shaped groove, thereby completing the end-to-end connection of the two tower barrels, but there is still a certain risk of leakage.
