旋流板塔工作原理

来源:admin(传梦环保整理发布)   时间:2018-08-28

旋流板塔工作原理


旋流板塔是一种喷射型塔板洗涤器
旋流板塔塔板叶片如固定的风车叶片,气流通过旋流板塔叶片时产生旋转和离心运动,吸收液通过旋流板塔中间盲板均匀分配到每个叶片,形成薄液层,与旋转向上的气流形成旋转和离心的效果,喷成细小液滴,甩向旋流板塔塔壁后。液滴受重力作用集流到旋流板塔集液槽,并通过降液管流到下一旋流板塔塔板的盲板区。具有一定风压、风速的待处理气流从旋流板塔的底部进,上部出。吸收液从旋流板塔的上部进,下部出。气流与吸收液在旋流板塔内作相对运动,并在旋流塔板的结构部位形成很大表面积的水膜,从而大大提高了吸收作用。每一层的吸收液经旋流离心作用掉入边缘的旋流板塔收集槽,再经导流管进入下一层旋流板塔塔板,进行下一层的吸收作用。
旋流板塔主要机制是尘粒与液滴的惯性碰撞,离心分离和液膜粘附等。这种旋流板塔塔板由于开孔率较大,允许高速气流通过,因此负荷较高,处理能力较大,压降较低,操作弹性较大。其气液接触时间较短,旋流板塔适合于气相扩散控制的过程,如气液直接接触传热、快速反应吸收等。因此脱硫过程中所用的脱硫剂应该是快速反应吸收型的,不适合用碳酸钙等反应速度较慢的脱硫剂。
旋流板塔在烟道入口处设计初级喷淋装置,当烟气经进口烟道,与布置在进口烟道段的喷淋形成的水雾进行传质换热,得到初步降温和去除部分二氧化硫,切向进入旋流板塔吸收塔。烟气在旋流板塔吸收塔内通过旋流气动装置的加速和旋流,烟尘与经过雾化的吸收液发生碰撞、附着、凝聚、离心分离等综合性的作用,被甩到旋流板塔塔壁,随旋流板塔塔壁水膜流向旋流板塔塔底。旋流板喷淋塔除尘效率可以达到98.5%以上。通过旋流气动装置的设置,使烟气在同样高度的筒体内旋转次数增加、通过的路径增长,气相紊动剧烈,烟气与吸收液在时间和空间上得到充分的碰撞、接触、溶解、吸收。
