THERMOELECTRIC FRESHENING PLANT Russian patent published in 2004 - IPC

FIELD: processes for producing freshened water, namely freshening plants for producing freshened water from sea water. SUBSTANCE: thermoelectric freshening plant includes working chamber in the form of horizontally extended hollow rectangular parallelepiped made of heat insulation material and having no one of its small lateral faces. Volume of working chamber is divided by three arranged one over another mutually communicated ducts (for draining concentrated brine, supplying sea water and discharging freshened water respectively) by means of two thin horizontal different-length partitions (length of lower partition exceeds that of upper partition and it is less than length of working chamber). Said partitions are made of high heat conduction material. Duct for supplying sea water has flange in its end. Two thermoelectric batteries are arranged in end portions of partitions. Heat separation joints of battery have thermal contact with needle type radiators. Needles of said radiators are arranged in staggered fashion and they are introduced into duct for supplying sea water. Heat absorption joints of batteries are joined with two other radiators which are introduced to ducts for draining concentrated brine and for discharging freshened water respectively. Volume of thermoelectric battery is filled with heat insulation material that lowers heat flux between all above mentioned ducts through thermoelectric battery and prevents thermal contact of thermoelectric battery with partitions. EFFECT: enhanced efficiency of distiller due to its improved design. 3 dwg
