Steam-water separation device for producing dry saturated steam

The utility model relates to a steam-water separation device for producing dry saturated steam, which comprises a flash evaporation nozzle and a steam-water separator, the steam-water separator is provided with a heat-conducting separation shell and a heating module arranged on the periphery of the separation shell, and the separation shell is provided with an inlet and an outlet. Two or more stages of separation flow channels which are sequentially communicated are constructed in the separation shell, the separation flow channels are correspondingly connected with the inlet and the outlet, and the separation flow channels are filled with heat conduction filter materials; the flash evaporation nozzle is assembled on the inlet and is externally provided with a superheated steam inlet and a hot water inlet, an atomizing nozzle is arranged in the flash evaporation nozzle and is used for atomizing hot water and then mixing the hot water with superheated steam for flash evaporation, and meanwhile, the steam is dri
