噴淋凈化塔凈化原理

氣(qi)(qi)(qi)(qi)體(ti)凈(jing)化(hua)塔(ta)：屬兩(liang)相(xiang)逆向流(liu)填(tian)(tian)料吸(xi)收(shou)(shou)塔(ta)。廢(fei)氣(qi)(qi)(qi)(qi)體(ti)從廢(fei)氣(qi)(qi)(qi)(qi)處(chu)理(li)塔(ta)體(ti)下方進氣(qi)(qi)(qi)(qi)口沿切向進入(ru)凈(jing)化(hua)塔(ta)，在通風機的(de)動(dong)力作用下，迅速(su)(su)充滿進氣(qi)(qi)(qi)(qi)段(duan)(duan)(duan)空(kong)間，然后均(jun)勻地通過均(jun)流(liu)段(duan)(duan)(duan)上(shang)(shang)升到第(di)壹(yi)級(ji)(ji)填(tian)(tian)料吸(xi)收(shou)(shou)段(duan)(duan)(duan)。在填(tian)(tian)料的(de)表面上(shang)(shang)，氣(qi)(qi)(qi)(qi)相(xiang)中(zhong)酸(suan)性(xing)(xing)（或堿(jian)(jian)性(xing)(xing)）物(wu)質(zhi)與(yu)(yu)液(ye)相(xiang)中(zhong)堿(jian)(jian)性(xing)(xing)（或酸(suan)性(xing)(xing)）物(wu)質(zhi)發生(sheng)(sheng)化(hua)學反(fan)應(ying)，反(fan)應(ying)生(sheng)(sheng)成物(wu)質(zhi)（多為可(ke)溶性(xing)(xing)酸(suan)（堿(jian)(jian)）類）隨吸(xi)收(shou)(shou)液(ye)流(liu)入(ru)下部貯(zhu)液(ye)槽。未(wei)完(wan)全吸(xi)收(shou)(shou)的(de)酸(suan)性(xing)(xing)（或堿(jian)(jian)性(xing)(xing)）氣(qi)(qi)(qi)(qi)體(ti)繼續上(shang)(shang)升進入(ru)第(di)壹(yi)級(ji)(ji)噴淋段(duan)(duan)(duan)。在噴淋段(duan)(duan)(duan)中(zhong)吸(xi)收(shou)(shou)液(ye)從均(jun)布的(de)噴嘴(zui)高速(su)(su)噴出，形成無數細小霧(wu)滴，與(yu)(yu)氣(qi)(qi)(qi)(qi)體(ti)充分混(hun)合接(jie)觸(chu)，繼續發生(sheng)(sheng)化(hua)學反(fan)應(ying)，然后酸(suan)性(xing)(xing)（堿(jian)(jian)性(xing)(xing)）氣(qi)(qi)(qi)(qi)體(ti)上(shang)(shang)升到二(er)級(ji)(ji)填(tian)(tian)料段(duan)(duan)(duan)、噴淋段(duan)(duan)(duan)進行與(yu)(yu)第(di)壹(yi)級(ji)(ji)類似的(de)吸(xi)收(shou)(shou)過程(cheng)。第(di)貮(er)級(ji)(ji)與(yu)(yu)第(di)壹(yi)級(ji)(ji)噴嘴(zui)密度不同，噴液(ye)壓力不同，吸(xi)收(shou)(shou)酸(suan)性(xing)(xing)（堿(jian)(jian)性(xing)(xing)）氣(qi)(qi)(qi)(qi)體(ti)濃度范圍也(ye)有所(suo)不同。在噴淋段(duan)(duan)(duan)及填(tian)(tian)料段(duan)(duan)(duan)兩(liang)相(xiang)接(jie)觸(chu)的(de)過程(cheng)也(ye)是傳熱與(yu)(yu)傳質(zhi)的(de)過程(cheng)。通過控制空(kong)塔(ta)流(liu)速(su)(su)與(yu)(yu)滯留(liu)時間保證(zheng)這(zhe)一過程(cheng)的(de)充分與(yu)(yu)穩定。廢(fei)氣(qi)(qi)(qi)(qi)處(chu)理(li)塔(ta)體(ti)的(de)上(shang)(shang)部是除(chu)霧(wu)段(duan)(duan)(duan)，氣(qi)(qi)(qi)(qi)體(ti)中(zhong)所(suo)夾的(de)吸(xi)收(shou)(shou)液(ye)霧(wu)滴在這(zhe)里(li)被(bei)清(qing)除(chu)下來，經過處(chu)理(li)后的(de)潔凈(jing)空(kong)氣(qi)(qi)(qi)(qi)從廢(fei)氣(qi)(qi)(qi)(qi)凈(jing)化(hua)塔(ta)上(shang)(shang)端排氣(qi)(qi)(qi)(qi)管排入(ru)大氣(qi)(qi)(qi)(qi)。
