| Geothermal Hydrologic cycle. ‘pumping either seawater or Sewage dirci to the hole to be heated by geothermal. Collect vibration from the hole to cool it dawn for harvesting the pure water. |
As shown in Figure (2), the proposed system encompasses the following sub- systems:
a) Geothermal well for hot water production
b) Pumping unit for seawater pumping into the geothermal well and for overcoming the pressure losses through the system.
c) Flash evaporation tank for steam generation.
d) Condenser unit for hot water condensation and fresh water production. e) Blow-down reservoir for salt concentration.
The system components are geothermal well, pumping system, flash tank, condenser and blow down reservoir. Seawater or saline water will be pumped through the condenser unit as a cooling water. It has two purposes; the first is to use it as cooling load for condensation, and the second is to be preheated before pumping into the geothermal well. Meanwhile, the preheated seawater will go through the geothermal well in order to gain a massive energy enthalpy as a hot water. Hot water will then be pumped towards the flashing tank for evaporation process.
The flash tank will transfer the hot water into a generating steam (salt free) in order to be condensed outside the condenser tubes. The salt free steam will then condensate on the condenser tubes generating the its energy rejection to the cooling water then to be collected as a fresh water in the accumulative tray. The rest of feed mass flow rate and non-condensable solute will be drawn away back to the blow down reservoir.
