A process of salt extraction from sea-water is provided to obtain salt economically from sea-water by employing an evaporation tube complex that endures air pressure. An evaporation tube complex comprises a vacuum evaporation tube(1), a cooling room(2), vacuum pumps(3,4), flat evaporation plate(5) having high frame on both sides for preventing a water leakage; an inflow tube(6) connected to the vacuum evaporation tube(1), outflow tubes(7,8), a connector(9) for flowing steam from the vacuum evaporation tube(1) to the cooling room(2). A process of salt extraction from sea-water comprises steps of: dropping the pressure in the vacuum evaporation tube(1) by means of the vacuum pump(3); providing the vacuum evaporation tube(1) with the inflow tube(6) and the evaporation plate(5); setting the evaporation plate(5) in the middle of the vacuum evaporation tube(1); and drawing the extracted salt in the vacuum evaporation tube(1) after distilled water from the cooling room(2) is drained through the outflow tubes(7,8) by the vacuum pump(3,4). |
