酸洗廢氣處理設備
工藝流程
酸洗廢氣處(chu)理設備由堿液噴淋塔、塔(ta)身(shen)、填料(liao)架、填料(liao)、噴(pen)(pen)(pen)(pen)淋(lin)(lin)(lin)管、水箱、霧滴分離器(qi)組成。以堿(jian)(jian)作(zuo)(zuo)為(wei)中(zhong)(zhong)(zhong)和(he)(he)液(ye)(ye)，處理(li)酸性廢(fei)(fei)氣。廢(fei)(fei)氣在經風管自(zi)(zi)底部進(jin)入堿(jian)(jian)液(ye)(ye)噴(pen)(pen)(pen)(pen)淋(lin)(lin)(lin)塔(ta)，自(zi)(zi)下(xia)(xia)向上(shang)(shang)流動，而噴(pen)(pen)(pen)(pen)嘴噴(pen)(pen)(pen)(pen)出的(de)(de)中(zhong)(zhong)(zhong)和(he)(he)液(ye)(ye)由上(shang)(shang)向下(xia)(xia)噴(pen)(pen)(pen)(pen)淋(lin)(lin)(lin)。從(cong)(cong)第(di)二(er)級(ji)(ji)中(zhong)(zhong)(zhong)噴(pen)(pen)(pen)(pen)出的(de)(de)中(zhong)(zhong)(zhong)和(he)(he)液(ye)(ye)與(yu)上(shang)(shang)升(sheng)(sheng)的(de)(de)廢(fei)(fei)氣進(jin)行氣液(ye)(ye)接(jie)觸，吸(xi)收中(zhong)(zhong)(zhong)和(he)(he)后(hou)(hou)中(zhong)(zhong)(zhong)和(he)(he)液(ye)(ye)往(wang)下(xia)(xia)淋(lin)(lin)(lin)濕第(di)二(er)級(ji)(ji)濾料(liao)層(ceng)(ceng)，使從(cong)(cong)下(xia)(xia)往(wang)上(shang)(shang)升(sheng)(sheng)的(de)(de)廢(fei)(fei)氣得(de)到(dao)氣液(ye)(ye)接(jie)觸吸(xi)收中(zhong)(zhong)(zhong)和(he)(he)，中(zhong)(zhong)(zhong)和(he)(he)液(ye)(ye)再(zai)(zai)向下(xia)(xia)淋(lin)(lin)(lin)濕*級(ji)(ji)濾料(liao)層(ceng)(ceng)，再(zai)(zai)一(yi)次獲(huo)得(de)氣液(ye)(ye)相接(jie)觸吸(xi)收中(zhong)(zhong)(zhong)和(he)(he)作(zuo)(zuo)用。同(tong)時還(huan)增大了(le)*級(ji)(ji)中(zhong)(zhong)(zhong)濾料(liao)的(de)(de)淋(lin)(lin)(lin)濕量，從(cong)(cong)而加大了(le)該(gai)濾料(liao)層(ceng)(ceng)的(de)(de)氣液(ye)(ye)比(bi)。正(zheng)因(yin)(yin)為(wei)廢(fei)(fei)氣是自(zi)(zi)下(xia)(xia)往(wang)上(shang)(shang)升(sheng)(sheng)，因(yin)(yin)此通(tong)過(guo)*級(ji)(ji)濾料(liao)層(ceng)(ceng)的(de)(de)廢(fei)(fei)氣濃度(du)zui高(gao)，這樣使高(gao)濃度(du)的(de)(de)廢(fei)(fei)氣曲折地從(cong)(cong)濾料(liao)間空隙通(tong)過(guo)向上(shang)(shang)升(sheng)(sheng)時，與(yu)向下(xia)(xia)流動的(de)(de)中(zhong)(zhong)(zhong)和(he)(he)液(ye)(ye)接(jie)觸吸(xi)收中(zhong)(zhong)(zhong)和(he)(he)，可使廢(fei)(fei)氣通(tong)過(guo)該(gai)濾層(ceng)(ceng)后(hou)(hou)濃度(du)急劇(ju)下(xia)(xia)降，然(ran)后(hou)(hou)再(zai)(zai)經過(guo)一(yi)排中(zhong)(zhong)(zhong)和(he)(he)液(ye)(ye)噴(pen)(pen)(pen)(pen)淋(lin)(lin)(lin)，廢(fei)(fei)氣與(yu)之吸(xi)收中(zhong)(zhong)(zhong)和(he)(he)后(hou)(hou)，濃度(du)再(zai)(zai)度(du)下(xia)(xia)降；然(ran)后(hou)(hou)再(zai)(zai)通(tong)過(guo)一(yi)個濾料(liao)層(ceng)(ceng)和(he)(he)一(yi)排中(zhong)(zhong)(zhong)和(he)(he)液(ye)(ye)噴(pen)(pen)(pen)(pen)淋(lin)(lin)(lin)的(de)(de)接(jie)觸吸(xi)收中(zhong)(zhong)(zhong)和(he)(he)，使廢(fei)(fei)氣的(de)(de)濃度(du)凈化到(dao)設計的(de)(de)預訂(ding)效果。在噴(pen)(pen)(pen)(pen)淋(lin)(lin)(lin)過(guo)程中(zhong)(zhong)(zhong)，廢(fei)(fei)氣中(zhong)(zhong)(zhong)的(de)(de)顆粒物(wu)或(huo)被水滴擊落或(huo)由于(yu)動能下(xia)(xia)降，在自(zi)(zi)身(shen)重(zhong)力作(zuo)(zuo)用下(xia)(xia)沉(chen)降到(dao)塔(ta)底部，zui后(hou)(hou)通(tong)過(guo)霧滴分離器(qi)，再(zai)(zai)次攔截廢(fei)(fei)氣中(zhong)(zhong)(zhong)的(de)(de)顆粒物(wu)及(ji)水霧。
的(de)霧(wu)滴分離器(qi)內部(bu)為改性(xing)PP材質(zhi)的(de)S型(xing)通道(dao)流向，且在S型(xing)凸面上設有彎勾(gou)，更(geng)有效去(qu)除(chu)水滴，進行(xing)水霧(wu)氣分離。
