Plate Type Fresh Water Generator mainly consists of evaporating, condensing chamber, ejector equipped to achieve vacuum, fresh water pump for delivering distilled water to storage tank. Heat exchanger is made of titanium. It's an energy-saving device because of using jacket water heat and lower boiling point of water in vacuum.
Furthermore the whole control system is to be designed as maker standard in according to our design purpose. Subject salinity meter is exclusively composed by maker, the design scheme concludes with temperature compensation.
The system designed under rough sea condition. That is for 32 0C sea water and 75 0C cylinder jacket cooling water. Under such circumstance, the unit can reach the max. distillate production capacity of 40t/d. Each unit consists of a condenser and an evaporator installed in a same chamber.
The sea water enters the plant at the condenser for cooling the water vapor, flows through the condenser. Then a little quantity is fed into the evaporating chamber and about half of them evaporating to vapor, the sea water is heated by the cylinder cooling water of main engine. The rest
quantity of sea water is led to the brine/air ejector, where brine and air is take off, and was discharged to overboard.
The pressure inside the chamber is less than atmosphere (vacuum), in this way the evaporating temperature usually is lower than 45 degree. The vapor rises from the evaporating chamber, which flows through the demister where brine mist is removed, and pure steam condensed to liquid in the condenser.
