摘要:
提出了把磁流化床技术应用于烟气脱硫的新思路,并研制了一套磁流化床脱硫实验装置.分析了磁场和铁磁颗粒的催化作用,明确在流化床外施加一个磁场且采用铁磁颗粒作为床料,可以增加流化床内的脱硫反应几率和反应效率.多种工况下的脱硫实验验证了磁流化床强化脱硫的理论分析,当采用床料dp=220 μm铁磁颗粒,施加外加磁场的磁感应强度B=40 mT,钙硫质量比m(Ca)/m(S)=1.85,入口烟气温度T0=250 ℃的工况条件下进行脱硫,获得了85.93%的脱硫效率.实验结果还表明,脱硫效率随着磁性颗粒粒径的变小或磁感应强度的增大而增加.
Abstract:
This paper describes a new method of the flue gas desulphurization in magnetically fluidized bed(FGD-MFB). An experiment device of the FGD-MFB was set up. The catalytic effects of the magnetic field and the magnetic particles for the desulphurization reaction was analysed theoretically. Experiment which verified this analysis was carried out. The experimental results show that the efficiency of the FGD-MFB increases with the increasing of the intensity of the magnetic field and decreasing of the diameter of the magnetic particles. When the mean diameter of the magnetic particles dp=220 μm, the intensity of the magnetic induction B=40 mT,the ratio of Ca(OH)2 and SO2 m(Ca)/m(S)=1.85, and the temperature of flue gas in inlet T0=250 ℃, the desulphurization efficiency is up to 85.93%.
