簡介
      SCX-V型濕式脫硫除塵設(shè)備是我司與湖南大學(xué)環(huán)境工程系的合作的科研產(chǎn)品，該技術(shù)為SCX-V型濕式脫硫除塵設(shè)備姐妹產(chǎn)品，具有一樣的高脫硫效率，特別適用于陶瓷輥軸窯爐廢氣脫硫除塵治理。

技術(shù)原理
      在設(shè)備內(nèi)預(yù)處理室利用放大效應(yīng)在自激室形成泡沫層，氣液得到充分接觸，煙氣得到初濕潤和初凈化后經(jīng)過兩級高效漩流裝置，發(fā)生碰撞、氣液傳質(zhì)、酸堿中和、絮凝等一系列復(fù)雜效應(yīng)，粉塵和硫化物并除去，最后通過一級脫水裝置，氣體中所含水滴被除去，之后再經(jīng)過一級除霧器，氣霧被除去，最終形成干潔的氣體，實現(xiàn)達標排放。

    1、脫硫原理

    本方案采用雙堿法脫硫。該法流程特點為先用可溶性的鈉堿吸收液在吸收塔內(nèi)進行脫硫，然后再用石灰乳或石灰石粉對鈉基吸收液進行再生，再生液繼續(xù)進行循環(huán)脫硫。

    雙減法有如下優(yōu)點：
   （1）設(shè)備內(nèi)鈉基清液作為吸收液，大大降低了結(jié)垢機率；
   （2）鈉基吸收二氧化硫速率高，在較低的液氣比下可得到較高的脫硫率，同時還可大大提高石灰的利用率。
    Ⅰ、 CaCO3+2SO2+H2O   →   Ca(HSO3)2+CO2(式中：Ca(HSO3)2是溶于水的，可防止堵塞。)                                                              
    Ⅱ、Ca(OH)2+SO2  →   CaSO3+H2O                                                                        
    Ⅲ、Na2CO3+SO2   →    Na2SO3+CO2                                                                      
    Ⅳ、2NaOH+SO2   →   Na2SO3+H2O                                                                        
    Ⅴ、Na2SO3+SO2+H2O   →   2NaHSO3                                                                      
    Ⅵ、2NaHSO3+Ca(OH)2   →  2NaOH+CaSO3+H2O                                                              
    Ⅶ、Na2SO3+Ca(OH)2    →  2NaOH+CaSO3                                                                  
                                                                                                       
    2、二氧化硫產(chǎn)生量                                                                                      
   
    鍋爐產(chǎn)生的二氧化硫產(chǎn)生量按計算：                                                                       
                                                                                                       
    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、油和氣取1。                                                                           
                                                                                                       
污水處理                                                                                               
                                                                                                       
   本系統(tǒng)脫硫液循環(huán)使用，運行無污水排放，沒有二次污染。

   1、除塵脫硫效率高、穩(wěn)定性強。                                                                          
   2、ＰＨ自控加藥功能、智能控制。                                                                        
   3、使用雙堿法脫硫，運行成本低。                                                                        
   4、體積小，重量輕，結(jié)構(gòu)新穎，集除塵、脫硫、脫水于一體。                                                
   5、噴淋液循環(huán)使用，不產(chǎn)生二次污染。
