工作原理(li)：

酸霧(wu)廢氣(qi)由(you)風管引(yin)入凈化塔(ta)，經過填料層，廢氣(qi)與氫氧化鈉吸收(shou)液進行氣(qi)液兩相充分(fen)接觸吸收(shou)中(zhong)和反應，酸霧(wu)廢氣(qi)經過凈化后，再經除霧(wu)板脫(tuo)水除霧(wu)后由(you)風機排入大氣(qi)。吸收(shou)液在塔(ta)底(di)經水泵增壓(ya)后在塔(ta)頂噴(pen)淋而(er)下，最后回流(liu)至塔(ta)底(di)循環使用(yong)。

產(chan)品特點：

1.除塵脫硫(liu)(liu)效率(lv)高，采用堿性(xing)洗滌水時，脫硫(liu)(liu)效率(lv)可達85%；

2.設備占地少，安裝(zhuang)方便；

3.耗(hao)水、耗(hao)電(dian)指標較低；

4.耐腐蝕、不磨損，使用壽(shou)命長；

5.設備運行(xing)可靠，維護簡單(dan)、方便。

組成(cheng)結構：

噴(pen)淋(lin)(lin)塔內填(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)(liao)層作為(wei)氣液(ye)兩(liang)(liang)相間接(jie)觸構件的傳質(zhi)設備(bei)。填(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)(liao)塔底部裝(zhuang)有填(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)(liao)支(zhi)承(cheng)板，填(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)(liao)以(yi)亂堆方式放置在(zai)(zai)支(zhi)承(cheng)板上。填(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)(liao)的上方安裝(zhuang)填(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)(liao)壓板，以(yi)防被(bei)上升氣流吹動(dong)。噴(pen)淋(lin)(lin)塔噴(pen)淋(lin)(lin)液(ye)從(cong)(cong)塔頂經液(ye)體(ti)(ti)分(fen)(fen)(fen)布(bu)器噴(pen)淋(lin)(lin)到填(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)(liao)上，并沿填(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)(liao)表面(mian)流下(xia)。氣體(ti)(ti)從(cong)(cong)塔底送入，經氣體(ti)(ti)分(fen)(fen)(fen)布(bu)裝(zhuang)置分(fen)(fen)(fen)布(bu)后(hou)，與液(ye)體(ti)(ti)呈逆流連(lian)續通過填(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)(liao)層的空隙，在(zai)(zai)填(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)(liao)表面(mian)上，氣液(ye)兩(liang)(liang)相密切(qie)接(jie)觸進行傳質(zhi)。 當液(ye)體(ti)(ti)沿填(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)(liao)層向(xiang)*動(dong)時(shi)，有時(shi)會出(chu)現壁流現象，壁流效(xiao)應造成(cheng)氣液(ye)兩(liang)(liang)相在(zai)(zai)填(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)(liao)層中(zhong)分(fen)(fen)(fen)布(bu)不均(jun)，從(cong)(cong)而(er)使傳質(zhi)效(xiao)率下(xia)降。因此(ci)，噴(pen)淋(lin)(lin)塔內的填(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)(liao)層分(fen)(fen)(fen)為(wei)兩(liang)(liang)段，中(zhong)間設置再分(fen)(fen)(fen)布(bu)裝(zhuang)置，經重(zhong)新分(fen)(fen)(fen)布(bu)后(hou)噴(pen)淋(lin)(lin)到下(xia)層填(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)(liao)上。
