垂直管道大多数配有可以增大气体与冷却水之间的接触面的装置,以保证冷却水和要冷却的气体能够充分接触。这种装置的选择取决于废气的成分。
气体与冷却液分别进入逆流塔。待冷却的废气从塔管的下端进入,并到达塔的上端。在顶部,冷却水均匀分布在整个管道横截面上方,并再次向下流到塔装置中并被收集到容器中。
由于是逆流,废气与冷却液之间形成了温度梯度,这对于有效地冷却和达到最大的冷却效果非常重要。
塔型的命名取决于塔内部的种类。区别有:
根据要求,每个塔型可与任何其他 GEA 净气机类型结合使用。
Used in industrial applications to cool gases upstream of electrostatic precipitators / bag filters for effective temperature control, gas volume reduction and humidification by the evaporation of water. GEA provides the two available atomization technologies utilized in the evaporative cooling process: hydraulic atomization and twin-fluid atomiz...
垂直净气立管,气体进口在上方,喷嘴呈放射状分布在气体进口下方的管道上。
在制造业中,许多基本应用场合都使用气体流骤冷的快速冷却。喷嘴的选择和选型是系统设计中最关键的决定。GEA 骤冷塔设计由一个敞口容器组成,在这里喷射的液体与气体接触。气体通过侧喷嘴进入塔底并向上流动,与塔顶喷射的液体相向流动。到气体到达顶部的气体出口时,已经将它冷却到了它的绝热饱和温度。
