增效剂在烧结烟气流化床脱硫中的影响OA

Aiming at the problem of large desulfurization load and high cost of desulfurizer in the circulating fluidized bed sintered flue gas desulfurization,this study built a fluidized bed flue gas desulfurization reactor to investigate the influence of synergist mass concentration,humidified water flow rate and gas flow rate on the desulfurization efficiency.The experimental results show that the addition of synergist could greatly improve the desulfurization capacity of slaked lime,and the optimal synergist mass concentration is 13 g/L.The desulfurization amount is positively correlated with the humidified water flow rate and negatively correlated with the gas flow rate.When the sintering flue gas flow increases,adding synergists and increasing humidified water flow rate are effective ways to improve the desulfurization efficiency and desulfurizer utilization so as to reduce costs.
