FIELD: physics.
SUBSTANCE: water desalting unit comprises three convergent-divergent air ducts formed by body 1 and baffle 2 situated at the inlet between its sidewalls. Condenser 3 is installed in the outlet part, bottom hole 4 in the body opens into tank 5. Pipeline 8 connects bottom of evaporation tank 6 with marine environment, tube 7 connects the tank top with intermediate part of the third air duct. Air flow accelerating in the air ducts achieves maximum velocity in a point of minimum cross-section, namely - in the intermediate part of the third air duct. Pressure in this point drops to the minimum. This results in filling tank 6 with seawater through pipeline 8 and in seawater boiling. Condensation takes place on condenser 3 surface. Fresh water produced in this way flows through hole 4 into tank 5.
EFFECT: invention enables seawater desalting with only air flow energy.
