Vaporization and overheating composite equipment

The utility model discloses vaporization and overheating composite equipment which comprises a shell, a heating tube bundle, a liquid atomizing nozzle, a heat and mass transfer filler metal ring and the like. The interior of the equipment is sequentially divided into a liquid atomization distribution cavity, a gas-liquid redistribution flow equalizing section and a heating section from top to bottom, the heating tube bundle is inversely arranged in the shell to provide heat for liquid vaporization and mixed gas overheating, and heat and mass transfer filler metal rings are filled in gaps of the heating tube bundle and a certain space at the tail end. According to the utility model, the design is novel, the structural arrangement is reasonable, the filled metal ring filler further uniformly distributes the liquid sprayed by the liquid atomizing nozzle, and the liquid is heated, vaporized and overheated, so that the difficult problems that the gas phase and the liquid phase are accurately metered, uniformly vap
