脱硫塔的缺点
Disadvantages of desulphurization tower
对于发电厂中一些大型的脱硫塔，大多均为直立高耸结构，基本上都达到50m以上。烟气脱硫塔不仅承受压力、温度和重力载荷，同时又承受风载荷和地震载荷等动力载荷。动力载荷的大小、方向甚至作用点随时间而变化的，动力载荷使结构产生加速度，引起共振现象，容易产生振动事故。
For some large desulfurization towers in power plants, most of them are upright and tall structures, which basically reach more than 50m. The flue gas desulfurization tower not only bears pressure, temperature and gravity loads, but also bears dynamic loads such as wind loads and earthquake loads. The size, direction and even point of action of the dynamic load vary with time. The dynamic load causes the structure to produce acceleration, causing resonance phenomenon and easy to produce vibration accidents.
