現在(zai)的靜電(dian)(dian)除塵(chen)器(qi)是(shi)以(yi)靜電(dian)(dian)凈化(hua)法(fa)來收(shou)集廢(fei)氣(qi)中的粉塵(chen),靜電(dian)(dian)除塵(chen)器(qi)在(zai)凈化(hua)工作(zuo)上主要是(shi)依賴電(dian)(dian)暈極和沉淀兩個系統來完成(cheng)的,當有塵(chen)氣(qi)體進(jin)人氣(qi)刺叭(ba)時,有塵(chen)氣(qi)體受(shou)到氣(qi)流分布板(ban)以(yi)及(ji)折流板(ban)的調整后,負氣(qi)流能較平均地進(jin)人電(dian)(dian)場.
1,靜(jing)電(dian)除塵器在使用2年后應(ying)大修(xiu)一次,大修(xiu)包括更換(huan)銹蝕或損壞的陰極(ji)線,陽極(ji)板和(he)振打部件,傳動部件(電(dian)機(ji),減速機(ji)),磨損易損件,保溫(wen)層等.
2 ,對于鎖風閥和星型給料器根(gen)據詳細情(qing)況,靜電除塵器按期給各潤(run)(run)滑(hua)點及(ji)凸輪,輥(gun)子表面供潤(run)(run)滑(hua)脂,特別留意各運(yun)動(dong)件的動(dong)作是否協調,有無錯(cuo)位,脫(tuo)落和松動(dong),按期檢查翻板,葉輪,內襯(chen)及(ji)其他易(yi)磨(mo)損情(qing)況,如已(yi)損壞(huai)應及(ji)時更換.
3,電(dian)場外部(bu)各動彈軸承和振打(da)傳動結構處(chu)應(ying)按期加油潤滑.檢測靜電(dian)除塵器的壓(ya)力(li)(li),以便及時了(le)解煙氣的工況溫度和壓(ya)力(li)(li),靜電(dian)除塵器在設備的使用過(guo)程中(zhong),進出口的煙道(dao)處(chu)安裝(zhuang)熱電(dian)偶和壓(ya)力(li)(li)表.
4,靜(jing)電(dian)(dian)除(chu)(chu)塵器陰極線,陽極板,分布板因(yin)種種原因(yin)造成積灰過厚,超過5～10MM時,應連(lian)續(xu)振(zhen)打(da)(da),如(ru)連(lian)續(xu)振(zhen)打(da)(da)無效時,應堵截高壓電(dian)(dian)進行(xing)振(zhen)打(da)(da),如(ru)斷電(dian)(dian)振(zhen)打(da)(da)仍不奏效時因(yin)進行(xing)人工清灰.靜(jing)電(dian)(dian)除(chu)(chu)塵器如(ru)排(pai)灰系統卸料(liao)器和鎖風閥(fa)出故障,應及時堵截高壓電(dian)(dian)排(pai)除(chu)(chu)故障后再進行(xing)出產.
5,靜電除塵(chen)器鏈(lian)機(ji)應(ying)常(chang)常(chang)檢查(cha)鏈(lian)條(tiao)及各傳(chuan)動部位,一旦發(fa)現(xian)有(you)殘缺損(sun)傷的機(ji)件(鏈(lian)板(ban)變形,嚴峻磨損(sun),鏈(lian)條(tiao)脫落)應(ying)及時修復更換,假如運(yun)一段時間后,發(fa)現(xian)鏈(lian)條(tiao)松(song)脫,靜(jing)電除塵器應(ying)去掉(diao)幾節鏈(lian)條(tiao),或用(yong)星輪張緊裝置調整,以(yi)鏈(lian)條(tiao)下垂(chui)度(du)相宜為準,保證(zheng)拉鏈(lian)機(ji)運(yun)行平(ping)穩,且按(an)期加油潤(run)滑. 6,靜電(dian)除(chu)塵器在(zai)使用(yong)時,應不按期小修(利用(yong)工藝出產泊車(che)機會)包括:檢(jian)查(cha)陰極(ji)線是(shi)否(fou)折斷,陽(yang)極(ji)板是(shi)否(fou)變形,陰陽(yang)極(ji)吊掛點是(shi)否(fou)有(you)脫(tuo)落(luo)松(song)動(dong)現(xian)象.檢(jian)查(cha)分布板孔是(shi)否(fou)有(you)堵(du)灰(hui),檫洗絕緣瓷軸,檢(jian)查(cha)有(you)無振打(da)錘脫(tuo)落(luo),檢(jian)查(cha)塵中(zhong)軸承和振打(da)傳動(dong)裝(zhuang)置,陰極(ji)保溫箱(xiang)處密封氈(zhan)被灰(hui)塵污染及時更(geng)換.更(geng)換損(sun)壞的零件,丈(zhang)量設備接地電(dian)阻.
7,各發蘭密封聯結部位,尤其是靜(jing)電除塵器檢驗(yan)門,防爆(bao)閥及(ji)觀察(cha)門處不(bu)得有漏風現象.
總上所述(shu)，在檢查靜(jing)電除塵(chen)器的(de)時候一定要仔細查看，尤其是靜(jing)電(dian)除(chu)(chu)塵(chen)器(qi)檢驗門、防爆閥及觀察門處(chu)不(bu)得有漏風現象.否則會對后(hou)期(qi)使(shi)用靜(jing)電(dian)除(chu)(chu)塵(chen)器(qi)的(de)除(chu)(chu)塵(chen)效果(guo)造(zao)成影響。
