摘    要:A new wet flue gas desulfurization method by reaction across the falling liquid film on the outside surface of axial finned-tube bundle and its principles of removal of SO2 are presented in this paper.The effects of different styles of tube bundle,and the pitch of tubes,flue gas velocity,gas-liquid ratio and flue gas temperature on desulphurization efficiency and the moisture content of flue gas are studied.The experiment results show that desulphurization effect is better for flue gas at 65℃,4.0m·s-1 against the tube bundle of 10 rows with relative pitch of staggered rows S1/d=2.1,S2/d=1.8.

关 键 词:轴向翅片管束  降膜  湿法烟气脱硫  含湿量

Abstract:A new wet flue gas desulfurization method by reaction across the falling liquid film on the outside surface of axial finned-tube bundle and its principles of removal of SO2 are presented in this paper.The effects of different styles of tube bundle,and the pitch of tubes,flue gas velocity,gas-liquid ratio and flue gas temperature on desulphurization efficiency and the moisture content of flue gas are studied.The experiment results show that desulphurization effect is better for flue gas at 65℃,4.0m·s-1 against the tube bundle of 10 rows with relative pitch of staggered rows S1/d=2.1,S2/d=1.8.
Keywords:finned-tube bundle  falling liquid film  wet flue gas desulfurization  humidity
