【Abstract】 Using the desulphurization bottle with the capacity of 1 700 to 4 000 cm 3 the desulfurization efficiency was conducted between the desulfurizers of steel mill red plaster and small sintering ore. The experiment proved that steel mill red plaster desulfuration is superior to small sintering ore; then the desulfuration efficiency contrast of several kinds of red plaster desulphurization charge ratio experiments were carried out: using the desulphurization agent made of the sawdust and red plaster is the rate of 1:1.5 to 1:2, with the moderate amount of the red plaster, bulk density and gas hole size, the best efficiency of the desulphurization was achieved when the resistance against the gas was not strong and the desulfuration efficiency was high in the late stage when sulfur capacity is rather high. According to the result of the experiments, the desulphurization made of the sawdust and red plaster at the ratio of 1:2 was put into production and found to be very effective. On the conditions that gas source averagely consisted of 3000 to 4000 mg/m 3 H 2S and desulphuization sulfur capacity was not higher than 80 %, desulphurization efficiency was averagely not lower than 99.5 %.更多还原
