A liquid
blast furnace slag granulation device comprises a gate, a granulator, a primary turntable, a water
nozzle, a secondary turntable, a drive device, a center
water pipe, a hopper and an
exhaust pipe, wherein the gate is arranged in the middle part of the upper part of the granulator, the upper half part of the granulator is in a
water cooled wall structure, the
lower half part of the granulator is contracted to form the hopper, the primary turntable, the water
nozzle, the secondary turntable, the drive device and a center
water pipe are arranged on the center line of the interior of the granulator, the
diameter of the secondary turntable is larger than that of the primary turntable, the water
nozzle is located between the primary turntable and the secondary turntable, the opening direction of the water nozzle points at the upper surface of the secondary turntable, the center
water pipe is arranged on the center of the turntables, the upper part of the center water
pipe is connected with the water nozzle, and the lateral wall of the granulator is connected with the
exhaust pipe. The liquid-state
blast furnace slag is crushed and condensated into
solid particles under the action of
centrifugal force and water film
bursting force. The invention utilizes the
centrifugal force and
bursting force of water flash
vaporization and expansion, enhances the
granulation effect, reduces
power consumption and equipment investment of the
granulation device, and has small
water consumption and water
resource saving.
