一、工作原理(li)：

    廢(fei)氣凈(jing)(jing)化噴(pen)淋塔主要(yao)(yao)的(de)運作方式是不斷酸霧(wu)廢(fei)氣由(you)風(feng)管引入(ru)凈(jing)(jing)化塔，經過填料層，廢(fei)氣與氫氧化鈉吸(xi)(xi)收(shou)(shou)液(ye)進行氣液(ye)兩相充分接觸(chu)吸(xi)(xi)收(shou)(shou)中和反應，酸霧(wu)廢(fei)氣經過凈(jing)(jing)化后(hou)，再經除(chu)霧(wu)板脫水除(chu)霧(wu)后(hou)由(you)風(feng)機排(pai)入(ru)大氣。吸(xi)(xi)收(shou)(shou)液(ye)在塔底(di)經水泵(beng)增壓后(hou)在塔頂(ding)噴(pen)淋而下(xia)，然后(hou)回流至塔底(di)循環(huan)使用。凈(jing)(jing)化后(hou)的(de)酸霧(wu)廢(fei)氣達到地方排(pai)放(fang)標準的(de)排(pai)放(fang)要(yao)(yao)求，低于國家排(pai)放(fang)標準。

二(er)、廢氣(qi)凈化噴淋塔特點(dian)

1.除(chu)塵脫硫效(xiao)率高(gao)，采用(yong)堿性(xing)洗滌水時，脫硫效(xiao)率可達(da)85%;

2.設備占地少，安裝(zhuang)方便;

3.耗水、耗電指(zhi)標(biao)較低;

4.耐腐蝕、不磨損(sun)，使(shi)用壽命長;

5.設備運行可靠，維(wei)護(hu)簡(jian)單、方便(bian)。

三(san)、廢氣凈化噴淋塔的結構

噴(pen)淋(lin)塔(ta)(ta)內(nei)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)層(ceng)(ceng)作(zuo)為(wei)氣(qi)(qi)液(ye)兩(liang)相(xiang)間(jian)接觸構件的(de)傳(chuan)質(zhi)設備。填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)塔(ta)(ta)底部裝(zhuang)有填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)支(zhi)承板(ban)，填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)以(yi)亂(luan)堆方式放置在支(zhi)承板(ban)上(shang)。填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)的(de)上(shang)方安裝(zhuang)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)壓(ya)板(ban)，以(yi)防被(bei)上(shang)升氣(qi)(qi)流(liu)吹動。噴(pen)淋(lin)塔(ta)(ta)噴(pen)淋(lin)液(ye)從塔(ta)(ta)頂經(jing)液(ye)體分(fen)(fen)(fen)布器噴(pen)淋(lin)到(dao)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)上(shang)，并沿(yan)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)表面(mian)流(liu)下。氣(qi)(qi)體從塔(ta)(ta)底送(song)入，經(jing)氣(qi)(qi)體分(fen)(fen)(fen)布裝(zhuang)置分(fen)(fen)(fen)布后(hou)，與液(ye)體呈(cheng)逆流(liu)連續通過填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)層(ceng)(ceng)的(de)空隙，在填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)表面(mian)上(shang)，氣(qi)(qi)液(ye)兩(liang)相(xiang)密切(qie)接觸進行傳(chuan)質(zhi)。當液(ye)體沿(yan)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)層(ceng)(ceng)向(xiang)下流(liu)動時，有時會出現(xian)壁流(liu)現(xian)象，壁流(liu)效應(ying)造成氣(qi)(qi)液(ye)兩(liang)相(xiang)在填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)層(ceng)(ceng)中分(fen)(fen)(fen)布不均(jun)，從而使傳(chuan)質(zhi)效率下降。因此，噴(pen)淋(lin)塔(ta)(ta)內(nei)的(de)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)層(ceng)(ceng)分(fen)(fen)(fen)為(wei)兩(liang)段，中間(jian)設置再分(fen)(fen)(fen)布裝(zhuang)置，經(jing)重新分(fen)(fen)(fen)布后(hou)噴(pen)淋(lin)到(dao)下層(ceng)(ceng)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)上(shang)。
