Product Description
The 20T/D Plate Type Evaporating Seawater Desalination Plant which mainly consists of evaporating and condensing chambers, ejector equipped for vacuum, control system, as well as relevant accessories for the system.
The system designed under rough sea condition. That is for 32oC sea water and 75oC cylinder jacket cooling water. Under such circumstance, the unit can reach distillate production capacity of 3-50 t/d. Each unit consists of a condenser and an evaporator installed in a same chamber.
Theory description of the fresh water genarator:
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.
The plant is a packaged unit, which is mounted on a base frame. All components and accessories such as fresh water pump, interconnecting pipe-work as well as inner cable are connected prior to delivery.
The sea water pump independently supplied for on-site installation on board, which is to be positioned under the light ballast line.
