[0021] Such as figure 1 As shown, a steel slag powder separation system using waste heat flue gas from a steel plant includes a waste heat flue gas source 22 of a steel plant, a waste heat flue mechanism for gathering waste heat flue gas from multiple locations in a steel plant, and a waste heat flue gas. Pressurizing mechanism 3, coal gas source 2, supplementary combustion hot air stove 4, static powder separator 5, feeding mechanism 6, coarse material storage mechanism 8, cyclone 7, dust removal mechanism, fine material storage mechanism 11 and exhaust mechanism 12 ;
[0022] The dust removal mechanism includes a bag filter 9 and a dust removal fan 10. The gas outlet of the bag filter 9 is connected to the gas inlet of the dust removal fan 10. The bag filter 9 and the dust removal fan 10 form a two-stage dust removal mechanism to further reduce the particulate matter in the exhaust gas. , Prevent particulate matter from polluting the environment.
[0023] The waste heat flue gas...
