NOVELTY - A seawater desalting system comprises an evaporation mechanism including two spaced conductors, and a condensing mechanism. Multiple thermoelectric refrigeration sheets and multiple temperature difference power generation chips are configured in the space between the two conductors. Heat generated by hot face of the thermoelectric refrigeration sheet is used for heating and evaporating seawater. The temperature difference power generation chip is driven to generate electricity by use of the temperature difference of the thermoelectric refrigeration sheet.    USE - Seawater desalting system.    ADVANTAGE - Regeneration energy is generated via the temperature difference of the thermoelectric refrigeration sheet during the seawater desalting process. Heat discharge quantity is greatly reduced.    DETAILED DESCRIPTION - A seawater desalting system comprises an evaporation mechanism including two spaced conductors, and a condensing mechanism connected with the evaporation mechanism. Multiple thermoelectric refrigeration sheets and multiple temperature difference power generation chips are configured in the space between the two conductors, and are alternatively distributed at intervals. Cold face and hot face of the thermoelectric refrigeration sheet and top face and bottom face of the temperature difference power generation chip respectively stick to the two conductors. Heat generated by the hot face of the thermoelectric refrigeration sheet is used for heating and evaporating seawater. Temperature generated by the cold and hot faces of the thermoelectric refrigeration sheet is conducted to the temperature difference power generation chip via the two conductors. The temperature difference power generation chip is driven to generate electricity by use of the temperature difference of the thermoelectric refrigeration sheet. The temperature difference power generation chip communicates with a current condenser for leading the generated current out to store and supplying to the thermoelectric refrigeration sheet to use.    DESCRIPTION OF DRAWING(S) - The drawing is a schematic diagram illustrating the seawater desalting system.
