酸堿廢氣處理
酸(suan)(suan)堿(jian)廢氣(qi)(qi)(qi)(qi)(qi)塔治理原理：酸(suan)(suan)性(xing)(xing)(xing)(xing)（堿(jian)性(xing)(xing)(xing)(xing)）氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)從(cong)(cong)塔體(ti)(ti)下(xia)方進(jin)(jin)氣(qi)(qi)(qi)(qi)(qi)口(kou)沿切向(xiang)進(jin)(jin)入(ru)(ru)凈(jing)化塔，然后均(jun)勻地通過(guo)均(jun)流段(duan)上升(sheng)到第(di)一(yi)(yi)級填料(liao)吸收(shou)(shou)(shou)段(duan)。在填料(liao)的(de)(de)表面上，氣(qi)(qi)(qi)(qi)(qi)相中酸(suan)(suan)性(xing)(xing)(xing)(xing)（堿(jian)性(xing)(xing)(xing)(xing)）物(wu)質與液(ye)相中堿(jian)性(xing)(xing)(xing)(xing)（酸(suan)(suan)性(xing)(xing)(xing)(xing)）物(wu)質發生化學反(fan)應(ying)。反(fan)應(ying)生成物(wu)（多(duo)數為可溶性(xing)(xing)(xing)(xing)鹽類）隨吸收(shou)(shou)(shou)液(ye)流入(ru)(ru)下(xia)部貯液(ye)槽。未完全吸收(shou)(shou)(shou)的(de)(de)酸(suan)(suan)性(xing)(xing)(xing)(xing)（堿(jian)性(xing)(xing)(xing)(xing)）氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)繼(ji)續上升(sheng)進(jin)(jin)入(ru)(ru)第(di)二級噴(pen)(pen)淋段(duan)。在噴(pen)(pen)淋段(duan)中吸收(shou)(shou)(shou)液(ye)從(cong)(cong)均(jun)布(bu)的(de)(de)噴(pen)(pen)嘴高(gao)速(su)(su)噴(pen)(pen)出(chu)，形成無(wu)數細(xi)小霧滴與氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)充分(fen)混合(he)、接觸(chu)、繼(ji)續發生化學反(fan)應(ying)。第(di)二級與第(di)一(yi)(yi)級噴(pen)(pen)嘴密度(du)不(bu)同(tong)，噴(pen)(pen)液(ye)壓力不(bu)同(tong)，吸收(shou)(shou)(shou)酸(suan)(suan)性(xing)(xing)(xing)(xing)（堿(jian)性(xing)(xing)(xing)(xing)）氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)濃度(du)范圍也有所(suo)不(bu)同(tong)。通過(guo)控(kong)制空(kong)塔流速(su)(su)與滯貯時間保證這一(yi)(yi)過(guo)程的(de)(de)充分(fen)與穩定。對于某些化學活潑性(xing)(xing)(xing)(xing)較差的(de)(de)酸(suan)(suan)性(xing)(xing)(xing)(xing)（堿(jian)性(xing)(xing)(xing)(xing)）氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)，尚需在吸收(shou)(shou)(shou)液(ye)中加入(ru)(ru)一(yi)(yi)定量的(de)(de)表面活性(xing)(xing)(xing)(xing)劑。塔體(ti)(ti)的(de)(de)最上部是除(chu)霧段(duan)，氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)中所(suo)夾帶的(de)(de)吸收(shou)(shou)(shou)液(ye)霧滴在這里(li)被清(qing)除(chu)下(xia)來，經過(guo)處理后的(de)(de)潔凈(jing)空(kong)氣(qi)(qi)(qi)(qi)(qi)從(cong)(cong)凈(jing)化塔上端排氣(qi)(qi)(qi)(qi)(qi)管排出(chu)。
