RESEARCH ON FLUE GAS DESULFURIZATION USING MODIFIED DOUBLE-RECYCLING AND MULTI-STAGE WATER FILM TOWER

Song Siyang Tian Lijiang Wang Ze,

摘要: 以改进后的双循环多级水幕塔对烟气进行脱硫性能研究,利用双循环不同p H值控制的优点和多级水幕的效果,增加气液接触面积和传质动力,提高SO2吸收效果。在正交实验确定的最佳运行工况基础上,从烟气流量、上下两段p H值、L/G、SO2进气浓度等因素进行研究。结果表明,SO2进气浓度在5 000 mg/m3以下时,脱硫效率保持在93%以上。上段p H值为6.0,下段p H值为5.0,L/G在15左右时的脱硫效率和运行工况最佳,无结垢现象。改进后的吸收塔具有良好的应用前景,实验结果可对现场脱硫设备的调试和运行提供参考。

Abstract: The characteristics of flue gas desulfurization using modified double-recycling and multi-stage water film tower was evaluated in this paper． In order to increase the SO2 removal efficiency，contact probability of liquid phase and flue gas was enlarged through using multi-point pH control and multi-stage water film． Factors such as flue gas velocity，pH of upper and lower tower section，ratio of liquid-flue gas and inlet SO2 concentration were selected to research the desulfurization effect． The result showed that SO2 removal efficiency kept above 93% when the inlet SO2 concentration was less than 5 000 mg /m3 ． There was no aggradation of CaSO4 or CaSO3 under the optimized pH condition of 6. 0 and 5. 0 for the upper and lower section of the tower，and 15 of L/G． The system has a favorable future of application，and a considerable reference for debugging and running of spot desulfurization equipments．
