Separated evaporation cavity plate type sea-water desalting plant

The utility model discloses an independent evaporation cavity plate type seawater desalination device which comprises a seawater inlet pipe, a fresh water outlet pipe, an evaporation cavity, a heating plate group and a condensate plate group. The seawater inlet pipe, the fresh water outlet pipe, the evaporation cavity, the heating plate group and the condensate plate group are communicated by a pipeline, a water-jetting ejector is arranged at the seawater inlet pipe, a condensate pump is arranged between the fresh water outlet pipe and the condensate plate group, and the condensate pump is communicated with the condensate plate group by the pipeline. The heating plate group and the condensate plate group are arranged outside the evaporation cavity, in addition, the heating plate group and a heat exchange plate of the condensate plate group are vertically arranged. The evaporation cavity is communicated with the heating plate group by a steam inlet pipe and is communicated with the condensate plate group by a
