Problems solved by technology
[0002] At present, the lime-gypsum method accounts for a large proportion of desulfurization devices in the iron and steel industry; from the perspective of usage, the removal rate of impurities in ordinary slag extractors is not very high, resulting in some large particles of impurities being desulfurized in the absorption tower. The desulfurization process is the absorption The slurry inside the tower is pumped to the spray layer by the circulation pump, and then discharged after reaching a certain density in the tower, which is a cycle process, so the large particles of impurities will damage the anti-corrosion layer in the absorption tower during the cycle, wear the circulation pump and cause desulfurization Serious slag accumulation in the tower
