[0033] (1) Liquid steel slag at a temperature of 1500-1700°C is poured from the slag tank to the inlet of the granulator. After granulation, it enters the inlet of the rotary reaction cooling device from the outlet, mixes with biomass, and pyrolyzes the biomass. Then steel slag and biomass pyrolysis coke are transported to the outlet of the rotary reaction cooling device, and discharged after being cooled by cooling water; the continuous input mass ratio of cooling water for cooling steel slag to steel slag is 1:4; the continuous input mass ratio of biomass to steel slag 1:2;
[0034] (2) The cooling water in step (1) is fed from the outlet of the rotary reaction cooling device, sprayed onto the surface of the steel slag, heated and converted into water vapor; the water vapor then flows in the opposite direction with the steel slag and exchanges heat, and is transported to the inlet of the rotary reaction cooling device Mixed with biomass pyrolysis gas; the mixed gas is then s...
