摘要
通过试验确定了由NaH_2PO_4和Na_2B_4O_7组成的缓冲溶液作为废气脱硫的吸收液.考察了吸收液中NaH_2PO_4浓度、吸收液中NaH_2PO_4/Na_2B_4O_7值、吸收液中SO_2含量、吸收温度和液气比等因素对SO_2脱除率的影响规律.在此基础上确定了在喷射塔中用该吸收液脱除废气中SO_2的适宜工艺条件.
The buffer solution containing NaH2PO4 and Na2B4O7 has been selected as the absorbents to remove SO2 from waste gases. The effects of the concentration of NaH2PO4, NaH2PO4/Na2B4O7, the concentration of SO2 in the solution, temperature and the ratio of liquid/gas on SO2 absorptivity were investigated. The optimum conditions in jet tower for removing SO2 from waste gases were studied.
