Description

Technical field [0001] The invention belongs to the technical field of stator cooling water treatment for hydrogen-cooled generator sets of nuclear power plants, and particularly relates to a movable resin bed external flushing device and a flushing method thereof. Background technique [0002] Two TBB-1000-2У3 hydrogen-cooled generator sets in the first phase of a nuclear power plant use a water-hydrogen-hydrogen cooling method, and the stator water is mainly used to cool the stator windings. The stator cooling water system consists of a cation bed loaded with cation resin and a mixed ion bed loaded with cation resin and anion resin. The volume of each ion bed is about 80L. When the unit power is running, when the system cooling water conductivity increases, put into operation the hybrid ion filter (30 liters of positive resin, H-type; 30 liters of negative resin, OH-type), when the PН value of the system cooling water drops , Put into operation the positive ion filter (60 lite...
