Hot engine cooling water is pumped by the engine circulating pump
through the seawater heater and back to the engine circulating system.
This water is not affected in any way except that some heat is removed.
This is the heat that boils the seawater in the distilling shell.
As this takes place under deep vacuum, the seawater is boiled at
a very low temperature (46-60º).
Raw seawater is pumped continuously through the fresh water condenser.
Most of the seawater is then discharged to sea. A certain quantity,
however, is fed into the distilling shell where it is boiled, the
seawater concentrate, or brine, is continuously drawn off from the
distilling shell by a venturi ejector and discharged to sea.
The vapor or steam, produced by boiling the seawater, passes through
a monel mesh separator where any droplets of water or entrained
particles are removed. Thus, only pure vapor enters the fresh water
condenser section. This vapor passes over the tubes of the fresh
water condenser where it is condensed by the cool seawater flowing
through the tubes. The resultant fresh water is pumped from there
to the storage tank by the fresh water pump.
The distilling shell vacuum is maintained by evacuating the noncondensable
gases from the shell with a venturi ejector. All fresh water is
monitored by the salinity control system with automatic dumping
should the water contain more than 4 ppm. of salt.
Safe design against failure protects valuable freshwater storage
from possible salt contamination.
