酸堿廢氣洗滌(di)塔
一、設備概況
本凈化塔采用PVC、PP、FRP等制(zhi)成，內設逆向填料吸收系(xi)(xi)統(tong)(tong)、噴淋系(xi)(xi)統(tong)(tong)、脫霧(wu)裝(zhuang)置系(xi)(xi)統(tong)(tong)、下設供(gong)水(shui)箱、供(gong)水(shui)泵系(xi)(xi)統(tong)(tong)、進(jin)出風口、風機、風管(guan)、吸罩組成系(xi)(xi)統(tong)(tong)。
二、工(gong)作(zuo)原理
酸性氣體凈化塔屬兩(liang)相逆(ni)向流填料吸收(shou)塔。
酸(suan)性(xing)氣(qi)體(ti)(ti)(ti)從(cong)(cong)(cong)塔體(ti)(ti)(ti)下方進(jin)氣(qi)口沿(yan)切(qie)向進(jin)入(ru)凈(jing)化塔，在通風機(ji)的動力(li)作用(yong)下，迅(xun)速充(chong)(chong)滿進(jin)氣(qi)段(duan)(duan)空(kong)間(jian)(jian)，然(ran)后(hou)均(jun)(jun)勻地通過均(jun)(jun)流(liu)段(duan)(duan)上(shang)升到(dao)(dao)第(di)一(yi)(yi)級(ji)填(tian)料(liao)吸(xi)(xi)收(shou)(shou)段(duan)(duan)。在填(tian)料(liao)的表面上(shang)，氣(qi)相(xiang)中(zhong)酸(suan)性(xing)物(wu)質與(yu)(yu)(yu)液(ye)相(xiang)中(zhong)堿性(xing)物(wu)質發生(sheng)化學反(fan)應。反(fan)應生(sheng)成(cheng)(cheng)物(wu)油（多(duo)數為可溶性(xing)鹽(yan)類）隨吸(xi)(xi)收(shou)(shou)液(ye)流(liu)入(ru)下部貯(zhu)液(ye)槽(cao)。未完全(quan)吸(xi)(xi)收(shou)(shou)的酸(suan)性(xing)氣(qi)體(ti)(ti)(ti)繼(ji)(ji)續上(shang)升進(jin)入(ru)第(di)一(yi)(yi)級(ji)噴(pen)淋(lin)(lin)段(duan)(duan)。在噴(pen)淋(lin)(lin)段(duan)(duan)中(zhong)吸(xi)(xi)收(shou)(shou)液(ye)從(cong)(cong)(cong)均(jun)(jun)布的噴(pen)嘴高速噴(pen)出(chu)，形成(cheng)(cheng)無數細(xi)小霧滴與(yu)(yu)(yu)氣(qi)體(ti)(ti)(ti)充(chong)(chong)分(fen)混(hun)合(he)、接(jie)觸(chu)、繼(ji)(ji)續發生(sheng)化學反(fan)應。然(ran)后(hou)酸(suan)性(xing)氣(qi)體(ti)(ti)(ti)上(shang)升到(dao)(dao)第(di)二級(ji)填(tian)料(liao)段(duan)(duan)、噴(pen)淋(lin)(lin)段(duan)(duan)進(jin)行與(yu)(yu)(yu)第(di)一(yi)(yi)級(ji)類似的吸(xi)(xi)收(shou)(shou)過程。第(di)二級(ji)與(yu)(yu)(yu)第(di)一(yi)(yi)級(ji)噴(pen)嘴密(mi)度不同(tong)，噴(pen)液(ye)壓(ya)力(li)不同(tong)，吸(xi)(xi)收(shou)(shou)酸(suan)性(xing)氣(qi)體(ti)(ti)(ti)濃度范圍也有所不同(tong)。在噴(pen)淋(lin)(lin)段(duan)(duan)及填(tian)料(liao)段(duan)(duan)兩相(xiang)接(jie)觸(chu)的過程也是材熱與(yu)(yu)(yu)傳質的過程。通過控制空(kong)塔流(liu)速與(yu)(yu)(yu)滯貯(zhu)時(shi)間(jian)(jian)保證這一(yi)(yi)過程的充(chong)(chong)分(fen)與(yu)(yu)(yu)穩定。對(dui)于某些化學活潑性(xing)較差的酸(suan)性(xing)氣(qi)體(ti)(ti)(ti)，尚需(xu)在吸(xi)(xi)收(shou)(shou)液(ye)中(zhong)加入(ru)一(yi)(yi)定量的表面活性(xing)劑。塔體(ti)(ti)(ti)的最上(shang)部是除(chu)霧段(duan)(duan)，氣(qi)體(ti)(ti)(ti)中(zhong)所夾帶的吸(xi)(xi)收(shou)(shou)液(ye)霧滴在這里被清除(chu)下來，經過處理后(hou)的潔(jie)凈(jing)空(kong)氣(qi)從(cong)(cong)(cong)凈(jing)化塔上(shang)端(duan)排氣(qi)管放入(ru)大氣(qi)。
