湿法脱硫烟气"消白"工艺研究与应用

Research and Application of Wet Desulfurization Flue Gas "Whitening" Process

我国多数燃煤电厂湿法烟气脱硫工艺饱和湿烟气直接排放,形成可视湿烟羽。当下已有许多环保节能技术对湿烟羽治理有明显效果,但技术指标尚未结合湿烟羽治理来制订。从研究结果来看,可行的方法包括烟气升温、直接冷却、降温再热等。在这些方法中,降温再热的适用性是较强的,而直接冷却则最弱。

Most of the wet flue gas desulfurization process of most coal-fired power plants in China is directly discharged by wet flue gas to form a visible wet plume. At present, many environmental-friendly energy-saving technologies have obvious effect on the treatment of wet-tobacco-feather, but the technical indexes have not been developed in combination with the treatment of wet-tobacco-feather. From the results of the study, the feasible method includes the temperature rise of the flue gas, the direct cooling, the temperature reduction and the re-heat. In these methods, the applicability of the cooling reheat is stronger and the direct cooling is the weakest.
