廢氣(qi)凈(jing)化(hua)塔工作原理
氣(qi)體(ti)(ti)凈化(hua)(hua)(hua)(hua)塔:屬兩(liang)相(xiang)逆向(xiang)流(liu)填(tian)料(liao)吸(xi)(xi)(xi)收(shou)塔。廢氣(qi)體(ti)(ti)從廢氣(qi)處(chu)(chu)理塔體(ti)(ti)下方進氣(qi)口沿切向(xiang)進入凈化(hua)(hua)(hua)(hua)塔,在(zai)(zai)通(tong)風機的(de)動力(li)(li)作用下,迅速充(chong)滿進氣(qi)段空間,然后均勻地通(tong)過(guo)均流(liu)段上(shang)升到(dao)一(yi)(yi)級(ji)填(tian)料(liao)吸(xi)(xi)(xi)收(shou)段。在(zai)(zai)填(tian)料(liao)的(de)表面上(shang),氣(qi)相(xiang)中(zhong)酸性(xing)(xing)(或(huo)堿(jian)(jian)(jian)性(xing)(xing))物質(zhi)(zhi)與液(ye)(ye)相(xiang)中(zhong)堿(jian)(jian)(jian)性(xing)(xing)(或(huo)酸性(xing)(xing))物質(zhi)(zhi)發(fa)(fa)生(sheng)化(hua)(hua)(hua)(hua)學(xue)反應(ying)(ying),反應(ying)(ying)生(sheng)成物質(zhi)(zhi)(多為可(ke)溶性(xing)(xing)酸(堿(jian)(jian)(jian))類)隨(sui)吸(xi)(xi)(xi)收(shou)液(ye)(ye)流(liu)入下部(bu)貯液(ye)(ye)槽(cao)。未完全吸(xi)(xi)(xi)收(shou)的(de)酸性(xing)(xing)(或(huo)堿(jian)(jian)(jian)性(xing)(xing))氣(qi)體(ti)(ti)繼(ji)續上(shang)升進入一(yi)(yi)級(ji)噴(pen)(pen)淋段。在(zai)(zai)噴(pen)(pen)淋段中(zhong)吸(xi)(xi)(xi)收(shou)液(ye)(ye)從均布的(de)噴(pen)(pen)嘴高速噴(pen)(pen)出(chu),形成無數細小霧(wu)滴,與氣(qi)體(ti)(ti)充(chong)分混(hun)合接(jie)觸,繼(ji)續發(fa)(fa)生(sheng)化(hua)(hua)(hua)(hua)學(xue)反應(ying)(ying),然后酸性(xing)(xing)(堿(jian)(jian)(jian)性(xing)(xing))氣(qi)體(ti)(ti)上(shang)升到(dao)二級(ji)填(tian)料(liao)段、噴(pen)(pen)淋段進行與一(yi)(yi)級(ji)類似的(de)吸(xi)(xi)(xi)收(shou)過(guo)程(cheng)。二級(ji)與一(yi)(yi)級(ji)噴(pen)(pen)嘴密度(du)不(bu)(bu)同(tong),噴(pen)(pen)液(ye)(ye)壓(ya)力(li)(li)不(bu)(bu)同(tong),吸(xi)(xi)(xi)收(shou)酸性(xing)(xing)(堿(jian)(jian)(jian)性(xing)(xing))氣(qi)體(ti)(ti)濃(nong)度(du)范圍也有所不(bu)(bu)同(tong)。在(zai)(zai)噴(pen)(pen)淋段及填(tian)料(liao)段兩(liang)相(xiang)接(jie)觸的(de)過(guo)程(cheng)也是(shi)傳熱與傳質(zhi)(zhi)的(de)過(guo)程(cheng)。通(tong)過(guo)控制空塔流(liu)速與滯留時間保證(zheng)這(zhe)一(yi)(yi)過(guo)程(cheng)的(de)充(chong)分與穩定(ding)。廢氣(qi)處(chu)(chu)理塔體(ti)(ti)的(de)上(shang)部(bu)是(shi)除(chu)霧(wu)段,氣(qi)體(ti)(ti)中(zhong)所夾(jia)的(de)吸(xi)(xi)(xi)收(shou)液(ye)(ye)霧(wu)滴在(zai)(zai)這(zhe)里被清除(chu)下來,經過(guo)處(chu)(chu)理后的(de)潔凈空氣(qi)從廢氣(qi)凈化(hua)(hua)(hua)(hua)塔上(shang)端排氣(qi)管(guan)排入大氣(qi)。
氣體(ti)凈化(hua)塔的性能特點(dian)
1、廢(fei)氣(qi)凈(jing)化(hua)(hua)(hua)設備(bei)適用范圍廣:化(hua)(hua)(hua)工(gong)(gong)、輕工(gong)(gong)、印染、醫藥、鋼鐵、機械、電子、儀表、電鍍等(deng)工(gong)(gong)業部門生產過程中排放的(de)有(you)機廢(fei)氣(qi)、硫酸(suan)(suan)(suan)(suan)、硝酸(suan)(suan)(suan)(suan)、 鹽酸(suan)(suan)(suan)(suan)、 氫氟酸(suan)(suan)(suan)(suan)等(deng)尾(wei)氣(qi)及硫氧化(hua)(hua)(hua)物(wu)(wu)(SOx)、氮氧化(hua)(hua)(hua)物(wu)(wu)(NOx)、碳氧化(hua)(hua)(hua)化(hua)(hua)(hua)物(wu)(wu)(CO、CO2)、氰化(hua)(hua)(hua)物(wu)(wu)(HCN)等(deng)酸(suan)(suan)(suan)(suan)性氣(qi)體,采用工(gong)(gong)業廢(fei)氣(qi)凈(jing)化(hua)(hua)(hua)設備(bei),都可(ke)得到滿(man)意的(de)效果(guo)。
2、廢(fei)氣(qi)(qi)凈(jing)(jing)化(hua)效(xiao)率高(gao):酸(堿)霧(wu)廢(fei)氣(qi)(qi)凈(jing)(jing)化(hua)塔采用(yong)二(er)級逆向(xiang)噴淋,填料比表面積大,由試驗研究(jiu)確定的氣(qi)(qi)比保證了性能穩定,對各種濃度的酸性(或(huo)堿性)廢(fei)氣(qi)(qi)凈(jing)(jing)化(hua)效(xiao)率均可(ke)達85%~95%。
3、廢(fei)(fei)氣處理設(she)備阻(zu)力(li)低(di):在保(bao)證足夠氣液(ye)接(jie)觸面積基礎上,工業廢(fei)(fei)氣凈(jing)化塔選(xuan)用(yong)空氣動力(li)特性填料品種(zhong)及結構形式,使設(she)備阻(zu)力(li)在額(e)定風量(liang)下不超過(guo)40毫米水柱(zhu),是國內各種(zhong)填料吸收塔中阻(zu)力(li)低(di)的一種(zhong)。這對于配用(yong)耐腐蝕低(di)壓(ya)通風機極為(wei)有(you)利。
4、廢(fei)氣(qi)處理(li)(li)設備占(zhan)地面積小(xiao):工(gong)業(ye)廢(fei)氣(qi)凈化(hua)處理(li)(li)塔采用(yong)PP、FRP等材質,將塔體(ti)、吸(xi)收液(ye)槽、循環泵(beng)、吸(xi)收液(ye)管道系統組(zu)合成一套完(wan)整的工(gong)業(ye)廢(fei)氣(qi)處理(li)(li)設備,結構緊湊,便于現場安裝及(ji)操作管理(li)(li),占(zhan)地面積小(xiao),無(wu)論對新建工(gong)程(cheng)還是技改項目(mu)都可適應。
廢氣凈化塔試用的填料:聚丙烯(xi)鮑爾環(huan)、不銹(xiu)鋼(gang)鮑爾環(huan)、多面空心(xin)球(qiu)、階梯環(huan)、花環(huan)填料等。
