摘要
通过湿法喷淋使锅炉烟气中的SO2等气体污染物被石灰水吸收而转入液相,再利用高压静电分离进一步去除烟气中的含硫雾滴及细尘粒等,是一种新型的高效脱硫除尘工艺。实验研究结果表明,在石灰水中Ca(OH)2含量为0.90%,石灰水用量为0.4 t/h的条件下的脱硫效率可达99%;湿式静电分离的电压对除尘效率具有显著影响,随着电压升高,除尘效率呈明显增大趋势。
A new and high efficient technology for flue gas desulphurization and dust removal was proposed. This technology includes two phases,in which the SO2 in the flue gas is transported to the liquid phase by lime water spraying,and the droplets with sulfur and dust particles are separated from the air by high voltage electrostatic. The experimental results show that when Ca( OH)2 content in the lime water was 0. 90%,the desulfurization efficiency can reach 99% with the flow capacity of 0. 4 t/h,and the voltage applied has a significant effect on the dust removal efficiency,which shows an obviously growing trend with the increase of the voltage.
