The invention belongs to the field of shaft seal water purification, and particularly relates to a rotary filter screen type corrosion product discharging device for a shaft seal water vertical pipe of a main pump of a nuclear power plant. Comprising an end cover, a filter screen and a shunt pipe, the filter screen is arranged in the shunt pipe, and the end cover covers the shunt pipe. The main pump shaft seal water vertical pipe rotary filter screen type corrosion product discharging device has the beneficial effects that through the design of the annular filter screen, water flowing out of the device and going to a main pump three-stage shaft seal must be filtered water, and the quality of the water for the shaft seal is guaranteed. The water flow of the water outlet of the shaft seal is utilized to push the filter screen to rotate, and the filter screen passing through the corrosion product outlet can be automatically flushed every time, so that the corrosion products in the water are discharged, and meanw
