| 摘 要： | 提出在烟气脱硫喷淋塔烟气进口设置导流板或采用切向进口，使烟气在塔内螺旋流动，以延长停留时间，加强气液湍动接触，并可改善系统的负荷调节适应能力。对不同进口结构的塔内流速分布、压力损失进行了实验研究，得出了旋流强度、压力损失等随导流板角度的变化关系，并将旋流情况与常规的直流进行了比较。

| Abstract: | The spiral flow created by baffles or tangent entrance is developed for a spray absorber of flue gas desulfurization, in order to prolong the gas residence time in the absorber, enhance the turbulent contact between gas and liquid, and improve the capability of gas flow regulation. The experiments are carried out for spiral flow field and pressure loss under the different baffle angles in an experimental absorber. The relationships with baffles are studied for both of the spiral strength and pressure loss. The behavior of spiral flow is compared with the conventional direct flow. |
