| 摘 要： | 烟气脱硫吸收塔结构形式复杂,掌握其动力特性是进行该类结构设计的重要基础.根据有限元理论,对带有高塔的烟气脱硫吸收塔,从如何考虑浆液影响的角度建立不同的有限元模型,对其进行动力特性分析,且考虑了内部浆液对吸收塔结构固有频率的影响.分析结果表明,浆液的存在对吸收塔高阶频率影响较大,对低阶频率,尤其是基频影响很小,偏差在1%以内,当要了解吸收塔的低阶频率时,为简化计算,可以不考虑浆液的影响. |
| 关 键 词： | 烟气脱硫吸收塔 有限元法 动力特性 固液耦合 |

| Abstract: | The structural form of electric plant smoke desulphurization absorber tower is complicated. It is important to study the dynamic properties of the structure. According to the theory of finite element,the different finite element model of smoke desulphurization absorber tower with high tower is established referring to whether considering the slurry in this paper. Then the dynamic properties analysis is computed and the effect of slurry affect on the absorber tower is analyzed. The optimum technological cond... |
