一、工作(zuo)原理：

    廢(fei)(fei)(fei)氣(qi)凈(jing)化(hua)(hua)(hua)(hua)(hua)噴淋塔主(zhu)要(yao)的運(yun)作方式是(shi)不斷酸(suan)霧(wu)廢(fei)(fei)(fei)氣(qi)由風管引(yin)入(ru)凈(jing)化(hua)(hua)(hua)(hua)(hua)塔，經過(guo)填(tian)料層，廢(fei)(fei)(fei)氣(qi)與氫氧化(hua)(hua)(hua)(hua)(hua)鈉吸收液(ye)進(jin)行氣(qi)液(ye)兩相充分接觸吸收中和反應，酸(suan)霧(wu)廢(fei)(fei)(fei)氣(qi)經過(guo)凈(jing)化(hua)(hua)(hua)(hua)(hua)后(hou)，再經除霧(wu)板脫水(shui)除霧(wu)后(hou)由風機(ji)排入(ru)大氣(qi)。吸收液(ye)在(zai)塔底經水(shui)泵增壓后(hou)在(zai)塔頂(ding)噴淋而下，然后(hou)回流至塔底循環(huan)使用。凈(jing)化(hua)(hua)(hua)(hua)(hua)后(hou)的酸(suan)霧(wu)廢(fei)(fei)(fei)氣(qi)達到(dao)地方排放(fang)標準的排放(fang)要(yao)求，低(di)于國家排放(fang)標準。

二、廢氣(qi)凈(jing)化噴淋塔特點(dian)

1.除塵脫硫效(xiao)率高，采(cai)用堿(jian)性(xing)洗滌水時(shi)，脫硫效(xiao)率可達(da)85%;

2.設備占地少，安裝方便;

3.耗水(shui)、耗電指標較(jiao)低;

4.耐腐蝕、不磨損，使用壽(shou)命長;

5.設備運(yun)行可靠(kao)，維護簡單、方便。

三、廢氣(qi)凈(jing)化(hua)噴淋塔(ta)的結構

噴(pen)(pen)淋(lin)(lin)塔內(nei)填(tian)(tian)(tian)料(liao)(liao)(liao)層作為(wei)氣(qi)液(ye)(ye)(ye)兩相間接(jie)觸構件的傳(chuan)質(zhi)設(she)備。填(tian)(tian)(tian)料(liao)(liao)(liao)塔底部裝有(you)填(tian)(tian)(tian)料(liao)(liao)(liao)支承(cheng)板，填(tian)(tian)(tian)料(liao)(liao)(liao)以亂(luan)堆方式(shi)放置(zhi)(zhi)(zhi)在支承(cheng)板上(shang)。填(tian)(tian)(tian)料(liao)(liao)(liao)的上(shang)方安裝填(tian)(tian)(tian)料(liao)(liao)(liao)壓板，以防被上(shang)升氣(qi)流(liu)(liu)吹動(dong)。噴(pen)(pen)淋(lin)(lin)塔噴(pen)(pen)淋(lin)(lin)液(ye)(ye)(ye)從(cong)塔頂經(jing)液(ye)(ye)(ye)體分(fen)布(bu)器噴(pen)(pen)淋(lin)(lin)到(dao)填(tian)(tian)(tian)料(liao)(liao)(liao)上(shang)，并沿填(tian)(tian)(tian)料(liao)(liao)(liao)表面(mian)(mian)流(liu)(liu)下。氣(qi)體從(cong)塔底送入，經(jing)氣(qi)體分(fen)布(bu)裝置(zhi)(zhi)(zhi)分(fen)布(bu)后(hou)，與液(ye)(ye)(ye)體呈逆流(liu)(liu)連續(xu)通(tong)過填(tian)(tian)(tian)料(liao)(liao)(liao)層的空隙，在填(tian)(tian)(tian)料(liao)(liao)(liao)表面(mian)(mian)上(shang)，氣(qi)液(ye)(ye)(ye)兩相密切接(jie)觸進行傳(chuan)質(zhi)。當液(ye)(ye)(ye)體沿填(tian)(tian)(tian)料(liao)(liao)(liao)層向下流(liu)(liu)動(dong)時，有(you)時會出現(xian)壁流(liu)(liu)現(xian)象，壁流(liu)(liu)效(xiao)應造成氣(qi)液(ye)(ye)(ye)兩相在填(tian)(tian)(tian)料(liao)(liao)(liao)層中(zhong)(zhong)分(fen)布(bu)不均，從(cong)而使傳(chuan)質(zhi)效(xiao)率下降。因此，噴(pen)(pen)淋(lin)(lin)塔內(nei)的填(tian)(tian)(tian)料(liao)(liao)(liao)層分(fen)為(wei)兩段，中(zhong)(zhong)間設(she)置(zhi)(zhi)(zhi)再(zai)分(fen)布(bu)裝置(zhi)(zhi)(zhi)，經(jing)重新分(fen)布(bu)后(hou)噴(pen)(pen)淋(lin)(lin)到(dao)下層填(tian)(tian)(tian)料(liao)(liao)(liao)上(shang)。
