廢(fei)氣凈化(hua)噴(pen)淋塔
一、工作原理：廢(fei)(fei)氣(qi)凈化噴(pen)(pen)淋塔主要的運作方(fang)式是不斷酸霧(wu)廢(fei)(fei)氣(qi)由風管引入凈化塔，經(jing)(jing)過(guo)填料(liao)層，廢(fei)(fei)氣(qi)與氫(qing)氧化鈉(na)吸收(shou)液進行氣(qi)液兩相(xiang)充分(fen)接觸吸收(shou)中和反應，酸霧(wu)廢(fei)(fei)氣(qi)經(jing)(jing)過(guo)凈化后，再經(jing)(jing)除霧(wu)板脫水除霧(wu)后由風機排入大氣(qi)。吸收(shou)液在(zai)塔底經(jing)(jing)水泵增壓后在(zai)塔頂噴(pen)(pen)淋而下，*后回(hui)流(liu)至塔底循環使用。凈化(hua)后的酸霧廢氣達到地方排放標準的排放要求，低于國家(jia)排放標準。
二(er)、廢(fei)氣凈化噴淋塔特點(dian)
1.除(chu)塵(chen)脫硫效(xiao)率高(gao)，采用堿性(xing)洗滌水時，脫硫效(xiao)率可達85%;
2.設(she)備占(zhan)地少，安裝方便;
3.耗水、耗電指(zhi)標(biao)較低;
4.耐腐蝕、不(bu)磨損，使用壽命長;
5.設備運行可(ke)靠，維護簡單、方便(bian)。
三、廢氣凈化噴(pen)淋塔的結構
噴(pen)(pen)淋(lin)塔(ta)內(nei)填(tian)(tian)(tian)(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)層(ceng)(ceng)作為氣(qi)液(ye)兩相(xiang)(xiang)間接觸(chu)構件的傳質設備。填(tian)(tian)(tian)(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)塔(ta)底(di)(di)部裝(zhuang)(zhuang)有(you)填(tian)(tian)(tian)(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)支承板(ban)，填(tian)(tian)(tian)(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)以(yi)亂(luan)堆(dui)方式放置(zhi)在(zai)支承板(ban)上(shang)(shang)。填(tian)(tian)(tian)(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)的上(shang)(shang)方安(an)裝(zhuang)(zhuang)填(tian)(tian)(tian)(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)壓板(ban)，以(yi)防被上(shang)(shang)升氣(qi)流(liu)(liu)(liu)吹動。噴(pen)(pen)淋(lin)塔(ta)噴(pen)(pen)淋(lin)液(ye)從(cong)(cong)塔(ta)頂經(jing)液(ye)體(ti)分(fen)(fen)(fen)布(bu)器噴(pen)(pen)淋(lin)到填(tian)(tian)(tian)(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)上(shang)(shang)，并沿填(tian)(tian)(tian)(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)表面流(liu)(liu)(liu)下(xia)。氣(qi)體(ti)從(cong)(cong)塔(ta)底(di)(di)送入(ru)，經(jing)氣(qi)體(ti)分(fen)(fen)(fen)布(bu)裝(zhuang)(zhuang)置(zhi)分(fen)(fen)(fen)布(bu)后，與液(ye)體(ti)呈(cheng)逆流(liu)(liu)(liu)連續通過填(tian)(tian)(tian)(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)層(ceng)(ceng)的空隙，在(zai)填(tian)(tian)(tian)(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)表面上(shang)(shang)，氣(qi)液(ye)兩相(xiang)(xiang)密切接觸(chu)進行傳質。當液(ye)體(ti)沿填(tian)(tian)(tian)(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)層(ceng)(ceng)向下(xia)流(liu)(liu)(liu)動時，有(you)時會出現(xian)壁流(liu)(liu)(liu)現(xian)象(xiang)，壁流(liu)(liu)(liu)效(xiao)應造成氣(qi)液(ye)兩相(xiang)(xiang)在(zai)填(tian)(tian)(tian)(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)層(ceng)(ceng)中(zhong)分(fen)(fen)(fen)布(bu)不均，從(cong)(cong)而使傳質效(xiao)率下(xia)降(jiang)。因此，噴(pen)(pen)淋(lin)塔(ta)內(nei)的填(tian)(tian)(tian)(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)層(ceng)(ceng)分(fen)(fen)(fen)為兩段，中(zhong)間設置(zhi)再分(fen)(fen)(fen)布(bu)裝(zhuang)(zhuang)置(zhi)，經(jing)重新分(fen)(fen)(fen)布(bu)后噴(pen)(pen)淋(lin)到下(xia)層(ceng)(ceng)填(tian)(tian)(tian)(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)上(shang)(shang)。
