摘　　要：铜矿浮选药剂添加时产生的CS_(2)废气影响了周边环境。采用超重力场技术协同NaOH净化CS_(2)废气,研究了转速、液体流量、气体流量、吸收液NaOH浓度等因素对CS_(2)净化效率以及传质系数(KG)的影响规律。结果表明,最佳试验条件为:转速1680 r/min、液体流量6.5 L/min、气体流量90 m^(3)/h、吸收液浓度0.4%NaOH,CS_(2)废气净化效率为95.90%。研究结果为工业CS_(2)异味气体净化提供了理论和实践基础。Address to the CS_(2)emissions generated during reagent addition in copper ore flotation,a method involving a high-gravity field technology combined with NaOH was adopted to purify CS_(2)waste gas.The effects of rotational speed,liquid flow rate,gas flow rate,and NaOH concentration in the absorption solution on CS_(2)purification efficiency and the mass transfer coefficient(KG)were studied.The results show that CS_(2)waste gas purification efficiency is 95.90%under the optimum conditions including rotational speed of 1680 r/min,liquid flow rate of 6.5 L/min,gas flow rate of 90 m^(3)/h,and absorption solution concentration of 0.4%NaOH.The research results provide both theoretical and practical foundations for industrial CS_(2)odor gas purification.
