Aiming at the head of a 435 m² sintering machine, the research on the removal characteristics of chemical agglomeration strengthening of fine particles and heavy metals (As, Cr, Cd, Ni, Cu, Pb, Zn, etc.) was carried out by installing chemical agglomeration enhanced dust removal system in front of ESP. The test results show that after chemical agglomeration, the mass concentration of PM₁₀, PM_2.5, PM₁ particles in the flue gas after the ESP is reduced by more than 49%, the average particle size of fly ash is increased by more than 46%, and the fine particles remove efficiency of ESP is promoted. After chemical agglomeration, the mass concentrations of seven heavy metals in fine particulate matter and fly ash increase, and the mass concentrations of gaseous heavy metals in the flue gas after the ESP decrease. It shows that agglomeration promotes the migration of gaseous heavy metals into fly ash particles, promotes the agglomeration and growth of fine particulate heavy metals. Chemical agglomeration can not only enhance the removal of fine particles, but also effectively improve the removal efficiency of heavy metals.
