【摘要】 由于非热等离子体烟气脱硫干式反应器中的主要过程是气相与固体表面液膜之间的复相反应, 采用湿式反应器应该更为合理. 对流光放电湿式烟气脱硫的动力学机制进行了分析, 导出了烟气脱硫率、能量效率和摩尔能耗与放电注入能量密度、传质效率因子和吸收液pH值的关系. 发现在放电注入能量一定的条件下, 设法提高传质效率因子和适当调节pH值, 能量效率可以显著提高, 摩尔能耗可以大幅度降低. 所得结果与过去已有实验结果吻合, 并表明有可能把该反应的能耗降到工业接受的水平.更多还原

【Abstract】 On the basis of heterogeneous reaction on the interf ac es between the gas and liquid films formed on the solid surface in a plasma flue gas desulfurization dry reactor,a wet type of reactor should be considered more reasonable.Simulation of the process in a wet reactor for flue gas desulfurizat ion by corona discharges was provided.Through deriving the dependence of the des ulfurization rate of flue gas,energy yield,mole energy consumption upon paramete rs of injected energy density,mass transfer efficiency factor and pH value of th e liquid absorbents,it was found that under the conditions of given energy injec tion of corona discharges mole energy consumption could be remarkably decreased when pH value was appropriately adjusted and the inner surface of the wet plasma reactor was appropriately porous.The results were in agreement with previous ex periments.Energy consumption could be reduced to an acceptable value.更多还原
