Embodiment 1
[0052] 1) Sintering - flue gas
[0053] Clinker, raw meal and mixed liquor discharged from the mixing tank (the main component is Ca 2+ , NO 3 - , a small amount of NO 2 - ) enters the mixer in the sintering device to obtain the mixture, which is mixed and burned in the sintering machine with the gas input from the blast furnace, the air preheater and the air input from the boiler, and the obtained sintered material enters the air preheater and the air preheater cools down The sintered material enters the blast furnace;
[0054] 2) Flue gas desulfurization and denitrification
[0055] The flue gas discharged from the sintering machine (composed of fine particles, dust, CO, CO 2 , SO 2 , NO X etc.) and the ozone from the ozone generating device merge into the desulfurization tower, and the waste liquid (mainly composed of Ca 2+ and SO 4 2- ) into the desulfurization sedimentation tank for precipitation, the desulfurization waste slurry in the lower layer of the sedim...
