In view of the difficulty in treating high concentration nitrogen oxides in explosive industry,a new absorption equipment－rotating packed bed was applied to increase the efficiency of the absorbent treatment of nitrogen oxides,reduce the costs of treatment and reach the discharging standards. NaOH solution was used as absorbent; the effect of gas flow,liquid gas ratio,high gravity factors and the concentration of NaOH solution on absorptivity were investigated. The results show that the absorption efficiency of single stage can amount to 81.8% at a gas flow rate of 2 m³·h^-1, liquid gas ratio of 20 L ·m^-3 and high gravity factors of 90. Absorption efficiency of double stages with oxidation equipment can amount to 95.4%.
