酸堿廢氣處理
酸(suan)堿(jian)廢氣(qi)(qi)塔(ta)治理(li)原(yuan)理(li)：酸(suan)性(xing)(xing)（堿(jian)性(xing)(xing)）氣(qi)(qi)體(ti)從(cong)(cong)塔(ta)體(ti)下(xia)方(fang)進(jin)氣(qi)(qi)口(kou)沿切向進(jin)入(ru)凈(jing)化塔(ta)，然后均(jun)勻地通過(guo)(guo)均(jun)流段上升到第(di)一(yi)級填(tian)料吸(xi)(xi)收(shou)段。在(zai)填(tian)料的(de)表(biao)面(mian)上，氣(qi)(qi)相(xiang)中酸(suan)性(xing)(xing)（堿(jian)性(xing)(xing)）物質與(yu)(yu)(yu)液(ye)相(xiang)中堿(jian)性(xing)(xing)（酸(suan)性(xing)(xing)）物質發生化學(xue)反(fan)應。反(fan)應生成物（多(duo)數(shu)為(wei)可溶(rong)性(xing)(xing)鹽類）隨吸(xi)(xi)收(shou)液(ye)流入(ru)下(xia)部貯液(ye)槽。未完全吸(xi)(xi)收(shou)的(de)酸(suan)性(xing)(xing)（堿(jian)性(xing)(xing)）氣(qi)(qi)體(ti)繼續上升進(jin)入(ru)第(di)二(er)級噴淋段。在(zai)噴淋段中吸(xi)(xi)收(shou)液(ye)從(cong)(cong)均(jun)布的(de)噴嘴高速(su)噴出(chu)，形(xing)成無數(shu)細小霧滴(di)與(yu)(yu)(yu)氣(qi)(qi)體(ti)充(chong)分混合、接觸、繼續發生化學(xue)反(fan)應。第(di)二(er)級與(yu)(yu)(yu)第(di)一(yi)級噴嘴密度(du)不同(tong)，噴液(ye)壓力不同(tong)，吸(xi)(xi)收(shou)酸(suan)性(xing)(xing)（堿(jian)性(xing)(xing)）氣(qi)(qi)體(ti)濃度(du)范圍也(ye)有所不同(tong)。通過(guo)(guo)控制空(kong)塔(ta)流速(su)與(yu)(yu)(yu)滯貯時間(jian)保證這(zhe)一(yi)過(guo)(guo)程的(de)充(chong)分與(yu)(yu)(yu)穩(wen)定。對于某些化學(xue)活潑(po)性(xing)(xing)較差的(de)酸(suan)性(xing)(xing)（堿(jian)性(xing)(xing)）氣(qi)(qi)體(ti)，尚需在(zai)吸(xi)(xi)收(shou)液(ye)中加(jia)入(ru)一(yi)定量的(de)表(biao)面(mian)活性(xing)(xing)劑。塔(ta)體(ti)的(de)最上部是(shi)除霧段，氣(qi)(qi)體(ti)中所夾帶的(de)吸(xi)(xi)收(shou)液(ye)霧滴(di)在(zai)這(zhe)里被清除下(xia)來(lai)，經過(guo)(guo)處理(li)后的(de)潔凈(jing)空(kong)氣(qi)(qi)從(cong)(cong)凈(jing)化塔(ta)上端排氣(qi)(qi)管(guan)排出(chu)。
