[0017] The specific structure, working principle and implementation manner of the device will be described in detail below with reference to the accompanying drawings.
[0018] The present invention includes a diversion groove 1 , a slag drop port 2 , a dry granulator 3 , a granulation nozzle 4 , and a slag discharge port 5 . The diversion trough 1 is made of refractory materials and is arranged on the top of the granulator. The lowest point of the diversion trough is provided with a slag drop port 2 that communicates with the dry granulator 3. narrow. The liquid blast furnace slag from the blast furnace slag ditch or slag tank flows into the diversion groove 1 , flows out from the slag drop opening 2 at the lower part of the diversion groove 1 and falls vertically into the granulator 3 . The upper part of the granulator 3 is provided with a granulation nozzle 4, and the included angle α between the outlet axis of the granulator nozzle 4 and the vertical direction is 0-90°, s...
