摘要/Abstract

摘要： 对烟气脱硫塔主体结构进行了研究, 结合已有的工程设计经验, 给出了确定脱硫塔主体结构尺寸的
具体步骤;尤其要计算喷淋塔内传质单元数和传质单元高度, 从而确定吸收高度, 并讨论了影响脱硫效率的一些主
要问题。结果表明, 对烟气进、出口角度进行调整以及用流体计算软件模拟吸收塔内增加气流分布板后喷淋效果改
善等措施, 可以使塔内烟气流速分布均匀, 增加了气液接触的有效传质面积,提高传质效率。

Abstract:

By the research of the flue main structure of gas desulfurization tower and combining experience in engineering design, the definite steps to determine the size of desulfurization towers main structure were given. The mass transfer units number and height of the spray tower were calculated to determine the absorption height particularly, and the major factors which impacted the desulfurization efficiency were discussed. The result show that the velocity of the tower flue gas distributed evenly and the effective transfer mass area of gas-liquid contacting which impacted the mass transfer efficiency is increased, by adjusting flue gas inlet and outlet angle, using computer software to simulate the absorber tower, increasing the air distribution plate to improve the spray effectiveness and so on. 
