工藝流程
涂裝(zhuang)酸洗(xi)廢(fei)氣(qi)處(chu)理設(she)備由(you)堿液噴淋塔(ta)、塔身、填(tian)料架(jia)、填(tian)料、噴(pen)淋(lin)(lin)管、水箱(xiang)、霧滴分(fen)離器組(zu)成(cheng)。以堿(jian)作(zuo)為中(zhong)(zhong)和(he)(he)液(ye)(ye)(ye)，處理涂裝酸性廢(fei)(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)。廢(fei)(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)在(zai)經(jing)風(feng)管自底(di)部進入(ru)堿(jian)液(ye)(ye)(ye)噴(pen)淋(lin)(lin)塔，自下(xia)向上(shang)(shang)流動(dong)，而噴(pen)嘴(zui)噴(pen)出(chu)的(de)中(zhong)(zhong)和(he)(he)液(ye)(ye)(ye)由(you)上(shang)(shang)向下(xia)噴(pen)淋(lin)(lin)。從第(di)二(er)級(ji)中(zhong)(zhong)噴(pen)出(chu)的(de)中(zhong)(zhong)和(he)(he)液(ye)(ye)(ye)與上(shang)(shang)升(sheng)(sheng)的(de)廢(fei)(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)進行氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)液(ye)(ye)(ye)接(jie)(jie)觸，吸(xi)收(shou)(shou)中(zhong)(zhong)和(he)(he)后(hou)中(zhong)(zhong)和(he)(he)液(ye)(ye)(ye)往下(xia)淋(lin)(lin)濕第(di)二(er)級(ji)濾(lv)(lv)(lv)料層(ceng)，使(shi)從下(xia)往上(shang)(shang)升(sheng)(sheng)的(de)廢(fei)(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)得到(dao)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)液(ye)(ye)(ye)接(jie)(jie)觸吸(xi)收(shou)(shou)中(zhong)(zhong)和(he)(he)，中(zhong)(zhong)和(he)(he)液(ye)(ye)(ye)再(zai)(zai)向下(xia)淋(lin)(lin)濕*級(ji)濾(lv)(lv)(lv)料層(ceng)，再(zai)(zai)一(yi)(yi)次獲(huo)得氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)液(ye)(ye)(ye)相接(jie)(jie)觸吸(xi)收(shou)(shou)中(zhong)(zhong)和(he)(he)作(zuo)用。同時(shi)還增大了(le)(le)*級(ji)中(zhong)(zhong)濾(lv)(lv)(lv)料的(de)淋(lin)(lin)濕量，從而加大了(le)(le)該(gai)濾(lv)(lv)(lv)料層(ceng)的(de)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)液(ye)(ye)(ye)比。正因(yin)為廢(fei)(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)是(shi)自下(xia)往上(shang)(shang)升(sheng)(sheng)，因(yin)此通(tong)(tong)過(guo)(guo)*級(ji)濾(lv)(lv)(lv)料層(ceng)的(de)廢(fei)(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)濃度(du)zui高，這樣使(shi)高濃度(du)的(de)廢(fei)(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)曲折地從濾(lv)(lv)(lv)料間空隙通(tong)(tong)過(guo)(guo)向上(shang)(shang)升(sheng)(sheng)時(shi)，與向下(xia)流動(dong)的(de)中(zhong)(zhong)和(he)(he)液(ye)(ye)(ye)接(jie)(jie)觸吸(xi)收(shou)(shou)中(zhong)(zhong)和(he)(he)，可使(shi)廢(fei)(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)通(tong)(tong)過(guo)(guo)該(gai)濾(lv)(lv)(lv)層(ceng)后(hou)濃度(du)急劇下(xia)降，然后(hou)再(zai)(zai)經(jing)過(guo)(guo)一(yi)(yi)排(pai)中(zhong)(zhong)和(he)(he)液(ye)(ye)(ye)噴(pen)淋(lin)(lin)，廢(fei)(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)與之吸(xi)收(shou)(shou)中(zhong)(zhong)和(he)(he)后(hou)，濃度(du)再(zai)(zai)度(du)下(xia)降；然后(hou)再(zai)(zai)通(tong)(tong)過(guo)(guo)一(yi)(yi)個濾(lv)(lv)(lv)料層(ceng)和(he)(he)一(yi)(yi)排(pai)中(zhong)(zhong)和(he)(he)液(ye)(ye)(ye)噴(pen)淋(lin)(lin)的(de)接(jie)(jie)觸吸(xi)收(shou)(shou)中(zhong)(zhong)和(he)(he)，使(shi)廢(fei)(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)的(de)濃度(du)凈(jing)化到(dao)設計的(de)預訂效(xiao)果(guo)。在(zai)噴(pen)淋(lin)(lin)過(guo)(guo)程中(zhong)(zhong)，廢(fei)(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)中(zhong)(zhong)的(de)顆(ke)粒(li)(li)物(wu)或(huo)被水滴擊(ji)落或(huo)由(you)于(yu)動(dong)能下(xia)降，在(zai)自身重力作(zuo)用下(xia)沉(chen)降到(dao)塔底(di)部，zui后(hou)通(tong)(tong)過(guo)(guo)霧滴分(fen)離器，再(zai)(zai)次攔截廢(fei)(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)中(zhong)(zhong)的(de)顆(ke)粒(li)(li)物(wu)及水霧。
涂裝酸(suan)洗廢氣處(chu)理設備的霧滴分離器內部為改性PP材質的S型通道流向，且(qie)在S型凸面上(shang)設有(you)彎勾，更有(you)效去除水滴，進行水霧氣分離。
