A vertical ring magnetic separator for de-ironing of pulverized coal ash, comprises a rotating ring(101), an inductive medium (102), an upper iron yoke (103), a lower iron yoke (104), a magnetic exciting coil (105), a feeding opening (106), a tailing bucket (107) and a water washing device (109). The feeding opening (106) is used for feeding the pulverized coal ash to be de-ironed, and the tailing bucket (107) is used for discharging the non-magnetic particle after de-ironing. The upper iron yoke (103) and the lower iron yoke (104) are respectively arranged at the inner and outer sides below the rotating ring (101). The water washing device (109) is arranged above the rotating ring (101). The inductive medium (102) is arranged in the rotating ring (101). The magnetic exciting coil (105) is arranged at the periphery of the upper iron yoke (103) and the lower iron yoke (104), so as to make the upper iron yoke (103) and the lower iron yoke (104) to be a pair of magnetic poles for generating a magnetic field in t
