General description：
Based on the general design scheme, the Fresh Water Generator which mainly consists of evaporating and condensing chambers, ejector equipped for vacuum, as well as relevant accessories for the system. The sea water pump is to be in loose supply.
Furthermore the whole control system is to be designed as maker standard in according to our design purpose. There equipped with LCD interface on control panel, for setting and communicating with operator.
The system designed with roughly crude sea condition. That is for 32℃ sea water and 75 ℃ cooling jacket water temperature. Under such circumstance, the unit can reach distillate production capacity of 15t/d with a sea temperature of 32 ℃. Each unit consists of a condenser and a heater installed in a same chamber.
Technical specification:
Theory description: The sea water enters the plant at the condenser, flows through the condenser. Then a little quantity is fed into the chamber. The remainder quantity of sea water fed the brine/air ejector, where brine and air is take off, and was discharge overboard.
The pressure inside the chamber is less than atmosphere (vacuum), in this way the boiling temperature is low (45 ℃). The vapor arise from the brine level in the plate heat exchanger, flows through the demister where atomized brine in the vapor is separated and pure steam condensers to distillate around the tube bundle of the condenser.
