Vaporization and overheating composite equipment

The invention 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. The device is novel in design and reasonable in structural arrangement, the filled metal ring filler further uniformly distributes liquid sprayed out of the liquid atomizing nozzle to be heated, vaporized and overheated, and the problems that gas and liquid phases are accurately metered, uniformly vaporized, overheated and accurately heated in a temperature control m
