DECOMPRESSION SEMICONDUCTOR THERMOELECTRIC DESALINATOR WITH UV RADIATION

Objectives. The development of a decompression semiconductor thermoelectric desalinator with ultraviolet radiation. Methods . The design of a decompression semiconductor thermoelectric desalinator with ultraviolet radiation makes it possible to decrease the boiling points of seawater and the obtained fresh water and brine by changing the pressure in the desalinatior thus increasing the device’s energy efficiency. Results . The use of the designed decompression semiconductor thermoelectric desalinator with ultraviolet radiation practically reduces the boiling point of seawater, completely eliminating Joule's parasitic heat release. The Peltier thermoelectric effect of heating and cooling is completely preserved, bringing the desalinator efficiency coefficient up to almost 100% and improving its energy-saving characteristics as a whole. Conclusion . A decompression semiconductor thermoelectric desalinator with ultraviolet radiation can be used to produce fresh water and concentrated solutions from any aqueous solutions, as well as to treat wastewater from industrial enterprises with simultaneous bacterial and virus disinfection. The construction materials of the desalination device are environmentally friendly.
