摘　　要：采用实心锥喷嘴自制的喷淋塔,用硼酸钠和盐酸配置的p H值=8.5的缓冲液作吸收剂,对空气中所含H2S气体进行吸收效果初探。实验结果证明:空气中H2S的脱除率不仅受气液量的影响,同时也受空气中H2S含量的影响。在偏碱性的缓冲溶液流量为600 L/h,气体流量为1.4 m3/h,H2S初始含量为9.0×10-3,H2S脱除率可达近80%。Using the sprinkling tower adopted solid wimble nozzle with sodium tetraborate buffer at pH 8.5, the removal efficiency of hydrogen sulfide was investigated. The experimental result shows that the removal efficiency of hydrogen sulfide is not only effected by gas flow rate and liquid flow rate but also the concentration of hydrogen sulfide. Furthermore, the absorption performance was also obtained under the experimental condition of the liquid flow rate of 600 L/h, the gas flow rate of 1.4 m^3/h and hydrogen sulfide concentration of 9.0 × 10^-3 ,showing the removal efficiency get to 80%.
