<p>[PROBLEMS] To provide an evaporator that in a seawater desalination apparatus according to the evaporation method, realizes easy stable reduction of seawater to mist while avoiding troubles, such as nozzle clogging attributed to scale components of seawater, to thereby reduce maintenance cost for the seawater desalination apparatus. [MEANS FOR SOLVING PROBLEMS] Seawater from a nozzle is fed to a turbine formed into a bladed wheel to thereby rapidly rotate the turbine. The blades of the rapidly rotated turbine collide with seawater droplets to thereby appropriately promote breakup of the liquid droplets, and the broken atomized water dropletsare dispersed into air by the centrifugal force generated by the rotation. The dispersed water droplets, while floating in the space of vacuum vessel (evaporation unit) of seawater desalination apparatus, evaporate by diffusion from the surface thereof.</p> |
