PP填料噴淋塔

PP填料噴淋塔工作原理

酸(suan)性(xing)(xing)(xing)氣(qi)(qi)(qi)體(ti)從塔(ta)體(ti)下(xia)方進(jin)氣(qi)(qi)(qi)口沿切向進(jin)入凈化(hua)(hua)(hua)塔(ta),在(zai)(zai)通(tong)風(feng)機的(de)(de)動力作用下(xia),迅速充滿進(jin)氣(qi)(qi)(qi)段(duan)(duan)(duan)(duan)空(kong)間(jian),然后均勻地通(tong)過(guo)(guo)均流段(duan)(duan)(duan)(duan)上升到(dao)(dao)第(di)一(yi)級填料吸(xi)(xi)收(shou)(shou)段(duan)(duan)(duan)(duan)。在(zai)(zai)填料的(de)(de)表(biao)(biao)面上,氣(qi)(qi)(qi)相中酸(suan)性(xing)(xing)(xing)物質與(yu)液(ye)(ye)(ye)相中堿性(xing)(xing)(xing)物質發生化(hua)(hua)(hua)學(xue)反(fan)應。反(fan)應生成(cheng)物油(多數(shu)為可溶性(xing)(xing)(xing)鹽(yan)類(lei))隨吸(xi)(xi)收(shou)(shou)液(ye)(ye)(ye)流入下(xia)部貯(zhu)液(ye)(ye)(ye)槽(cao)。未完全吸(xi)(xi)收(shou)(shou)的(de)(de)酸(suan)性(xing)(xing)(xing)氣(qi)(qi)(qi)體(ti)繼續上升進(jin)入第(di)一(yi)級噴(pen)淋段(duan)(duan)(duan)(duan)。在(zai)(zai)噴(pen)淋段(duan)(duan)(duan)(duan)中吸(xi)(xi)收(shou)(shou)液(ye)(ye)(ye)從均布的(de)(de)噴(pen)嘴(zui)高速噴(pen)出,形成(cheng)無數(shu)細(xi)小霧(wu)滴(di)與(yu)氣(qi)(qi)(qi)體(ti)充分(fen)混合、接觸、繼續發生化(hua)(hua)(hua)學(xue)反(fan)應。然后酸(suan)性(xing)(xing)(xing)氣(qi)(qi)(qi)體(ti)上升到(dao)(dao)第(di)二(er)級填料段(duan)(duan)(duan)(duan)、噴(pen)淋段(duan)(duan)(duan)(duan)進(jin)行與(yu)第(di)一(yi)級類(lei)似的(de)(de)吸(xi)(xi)收(shou)(shou)過(guo)(guo)程(cheng)。第(di)二(er)級與(yu)第(di)一(yi)級噴(pen)嘴(zui)密度(du)(du)不(bu)同,噴(pen)液(ye)(ye)(ye)壓力不(bu)同,吸(xi)(xi)收(shou)(shou)酸(suan)性(xing)(xing)(xing)氣(qi)(qi)(qi)體(ti)濃(nong)度(du)(du)范圍也(ye)有所不(bu)同。在(zai)(zai)噴(pen)淋段(duan)(duan)(duan)(duan)及填料段(duan)(duan)(duan)(duan)兩相接觸的(de)(de)過(guo)(guo)程(cheng)也(ye)是(shi)材熱與(yu)傳質的(de)(de)過(guo)(guo)程(cheng)。通(tong)過(guo)(guo)控制空(kong)塔(ta)流速與(yu)滯貯(zhu)時間(jian)保(bao)證這一(yi)過(guo)(guo)程(cheng)的(de)(de)充分(fen)與(yu)穩定(ding)(ding)。對(dui)于某(mou)些化(hua)(hua)(hua)學(xue)活(huo)潑性(xing)(xing)(xing)較差的(de)(de)酸(suan)性(xing)(xing)(xing)氣(qi)(qi)(qi)體(ti),尚(shang)需在(zai)(zai)吸(xi)(xi)收(shou)(shou)液(ye)(ye)(ye)中加入一(yi)定(ding)(ding)量的(de)(de)表(biao)(biao)面活(huo)性(xing)(xing)(xing)劑。塔(ta)體(ti)的(de)(de)最上部是(shi)除霧(wu)段(duan)(duan)(duan)(duan),氣(qi)(qi)(qi)體(ti)中所夾帶(dai)的(de)(de)吸(xi)(xi)收(shou)(shou)液(ye)(ye)(ye)霧(wu)滴(di)在(zai)(zai)這里被(bei)清除下(xia)來,經過(guo)(guo)處理后的(de)(de)潔凈空(kong)氣(qi)(qi)(qi)從凈化(hua)(hua)(hua)塔(ta)上端排氣(qi)(qi)(qi)管放入大氣(qi)(qi)(qi)。
