Nuclear power unit three-loop seawater strategic element recovery and waste heat utilization device

Abstract

The utility model discloses a nuclear power unit three loop seawater strategic element recovery and waste heat utilization device, it includes seawater screening system, element extraction system and generator export electricity taking module. Nuclear power unit three loop seawater strategic element recovery and waste heat utilization device set up seawater screening system in nuclear power unit three loop, realize three loop seawater further concentration, provide brine for element extraction system, and simultaneously produce desalination seawater. Element extraction system realizes nuclear power unit three loop waste heat's recovery, seawater strategic element cogeneration. Generator export electricity taking module can utilize the large amount of electric power produced when nuclear power peak shaving provides the operation electric power for seawater screening system and element extraction system. The device breaks through the single function limitation of traditional nuclear power unit three loop only for cooling, realizes concentration, extraction, waste heat recovery function integration through the combination design of seawater screening system and element extraction system, improves the comprehensive technical value of nuclear power system.
