摘要
SO_2是我国大气污染的主要污染源之一。现有SO_2成熟的脱除方法为湿式石灰石石膏法,这种方法在达到极高的SO_2脱除效率的同时也带来了很多弊端,如脱硫废水处理,高湿烟气排放等,在治理环境的同时也带来了新的污染,解决这一问题的根本方法在于改变脱硫技术,干法脱硫由于其避免腐蚀,不需要水的参与而引起人们的关注,介绍了几种典型的脱硫方法以提供参考。
SO2 is one of the main pollution sources of air pollution in China. The most mature desulfurization method is removed by wet limestone gypsum, which has the high SO2 removal efficiency. Howeve, it also brought a lot of drawbacks at the same time, such as desulfurization wastewater treatment, high humidity flue gas discharge and so on. The new pollution came up with the SO2 removal. The basic method to solve this problem is to change the desulfurization technology. Due to its avoidance of corrosion and avoid the water par- ticipation, dry FGD process has attracted peoples attention. It introduces several typical desulfurization methods to provide reference.
