Gas discharge pipe connects condenser in condenser upper side, and air discharge duct connects air through evaporation of seawater tank side.Air
Discharge pipe and steam flow into pipe and are distributed in the two diagonal of evaporation of seawater tank.Seawater flows into discharge pipe and is connected in evaporation of seawater tank bottom face
Evaporation of seawater tank.It is flexible hoses that seawater, which flows into discharge pipe, and seawater flows into discharge pipe and is suspended on evaporation of seawater tank side.Sea
Water flows into discharge pipe port position and flows into pipe import less than steam, and it is evaporation of seawater tank inland sea that seawater, which flows into discharge pipe port position,
Water peak level.It is closed with transparent thermal insulation material in evaporation of seawater tank deck face.
The condenser is the hollow cylinder for having more two-ports in the heat exchanger tube of top and bottom, and condenser top surface connects
Steam flow into pipe, condenser upper side connection air discharge duct, condenser bottom surface connection fresh water effuser, steam flow into pipe with
It is two diagonal to be arranged in condenser for air discharge duct.
The evaporation of seawater tank deck face is made of transparent thermal insulation material.
