SCX-V型湿式脱硫除尘设备

简介
      SCX-V型湿式脱硫除尘设备是我司与湖南大学环境工程系的合作的科研产品，该技术为SCX-V型湿式脱硫除尘设备姐妹产品，具有一样的高脱硫效率，特别适用于陶瓷辊轴窑炉废气脱硫除尘治理。

技术原理
      在设备内预处理室利用放大效应在自激室形成泡沫层，气液得到充分接触，烟气得到初湿润和初净化后经过两级高效漩流装置，发生碰撞、气液传质、酸碱中和、絮凝等一系列复杂效应，粉尘和硫化物并除去，最后通过一级脱水装置，气体中所含水滴被除去，之后再经过一级除雾器，气雾被除去，最终形成干洁的气体，实现达标排放。

    1、脱硫原理

    本方案采用双碱法脱硫。该法流程特点为先用可溶性的钠碱吸收液在吸收塔内进行脱硫，然后再用石灰乳或石灰石粉对钠基吸收液进行再生，再生液继续进行循环脱硫。

    双减法有如下优点：
   （1）设备内钠基清液作为吸收液，大大降低了结垢机率；
   （2）钠基吸收二氧化硫速率高，在较低的液气比下可得到较高的脱硫率，同时还可大大提高石灰的利用率。

    锅炉产生的二氧化硫产生量按计算：                                                                       
                                                                                                       
    W=2·K·B·S（t/h）                                                                                
    式中 B—耗油量（t/h）；                                                                                
    S—燃料含硫量（%）；                                                                                   
    K—SO2，煤取0.8、油和气取1。
