水噴淋廢氣凈化塔 PP噴淋塔 工業廢氣處理設備
噴淋塔結構特點及作用
噴(pen)淋(lin)塔用途(tu)：廢氣(qi)吸(xi)收(shou)、凈化(hua)，煙(yan)氣(qi)除(chu)塵(chen)，降溫(wen)等。
噴淋(lin)塔由塔體(ti)、填料、液體(ti)分(fen)布器、氣水(shui)分(fen)離(li)器、噴淋(lin)系統、循環水(shui)泵(beng)、循環水(shui)池、藥液儲存投加系統等單(dan)元(yuan)組成。
噴淋(lin)(lin)塔(ta)(ta)塔(ta)(ta)內(nei)填(tian)(tian)(tian)(tian)料(liao)(liao)層(ceng)(ceng)作(zuo)為氣(qi)(qi)液兩(liang)(liang)相間(jian)接(jie)觸構件的傳(chuan)質(zhi)(zhi)設(she)備。填(tian)(tian)(tian)(tian)料(liao)(liao)塔(ta)(ta)底(di)部裝(zhuang)有(you)填(tian)(tian)(tian)(tian)料(liao)(liao)支(zhi)承板(ban)，填(tian)(tian)(tian)(tian)料(liao)(liao)以亂堆(dui)方(fang)式放置(zhi)在(zai)(zai)支(zhi)承板(ban)上(shang)。填(tian)(tian)(tian)(tian)料(liao)(liao)的上(shang)方(fang)安裝(zhuang)填(tian)(tian)(tian)(tian)料(liao)(liao)壓板(ban)，以防被上(shang)升氣(qi)(qi)流(liu)(liu)(liu)(liu)吹動。噴淋(lin)(lin)液從塔(ta)(ta)頂(ding)經(jing)液體(ti)分(fen)(fen)布器噴淋(lin)(lin)到(dao)填(tian)(tian)(tian)(tian)料(liao)(liao)上(shang)，并沿填(tian)(tian)(tian)(tian)料(liao)(liao)表面流(liu)(liu)(liu)(liu)下。氣(qi)(qi)體(ti)從塔(ta)(ta)底(di)送入，經(jing)氣(qi)(qi)體(ti)分(fen)(fen)布裝(zhuang)置(zhi)分(fen)(fen)布后(hou)，與液體(ti)呈逆流(liu)(liu)(liu)(liu)連續通(tong)過填(tian)(tian)(tian)(tian)料(liao)(liao)層(ceng)(ceng)的空隙，在(zai)(zai)填(tian)(tian)(tian)(tian)料(liao)(liao)表面上(shang)，氣(qi)(qi)液兩(liang)(liang)相密切接(jie)觸進行傳(chuan)質(zhi)(zhi)。 當(dang)液體(ti)沿填(tian)(tian)(tian)(tian)料(liao)(liao)層(ceng)(ceng)向下流(liu)(liu)(liu)(liu)動時，有(you)時會出現(xian)壁(bi)流(liu)(liu)(liu)(liu)現(xian)象，壁(bi)流(liu)(liu)(liu)(liu)效(xiao)應造成氣(qi)(qi)液兩(liang)(liang)相在(zai)(zai)填(tian)(tian)(tian)(tian)料(liao)(liao)層(ceng)(ceng)中分(fen)(fen)布不均(jun)，從而使傳(chuan)質(zhi)(zhi)效(xiao)率下降。因此，噴淋(lin)(lin)塔(ta)(ta)內(nei)的填(tian)(tian)(tian)(tian)料(liao)(liao)層(ceng)(ceng)分(fen)(fen)為兩(liang)(liang)段，中間(jian)設(she)置(zhi)再(zai)分(fen)(fen)布裝(zhuang)置(zhi)，經(jing)重新分(fen)(fen)布后(hou)噴淋(lin)(lin)到(dao)下層(ceng)(ceng)填(tian)(tian)(tian)(tian)料(liao)(liao)上(shang)。
為(wei)了(le)避免氣(qi)體攜走噴(pen)(pen)淋液，在塔頂部(bu)氣(qi)水(shui)分離器(qi)，有(you)效(xiao)截留噴(pen)(pen)淋液。噴(pen)(pen)淋液循(xun)環(huan)使用，在使用過程中(zhong)會(hui)有(you)部(bu)分損(sun)失，位于塔底的循(xun)環(huan)水(shui)箱適(shi)時補充(chong)噴(pen)(pen)淋液。
