Abstract:
T his paper ex pounded the principle of jet bubbling flue gas desulfurizat ion and the st ructure of jet bubbling reactor ( JBR) . T he react ion kinetics of w et flue gas desulfurizat ion w as invest ig ated by using JBR. The experimental result s indicate that the desulfurizat ion process and the system operation ar e affected by pH value of absorption slurry , the submerg ence depth o f gas sparger L , g as pressure dro p Δp , weight per centage o f lime w and par ticle size of lime. Above 90% of SO2 remov al and above 95% of calcium ut ilizatio n as w ell as stable system o perat io n w itho ut scaling can be achieved by co nt rol ling pH= 5. 5~6. 5, L ≤200 mm, Δp ≤1 800 Pa, w ≤5 %, and using 200 mesh par ticles o f lime.
