濕電除塵(chen)器擁有捕集煙氣(qi)中霧滴、粉(fen)(fen)塵(chen)和微小塵(chen)粒的強大(da)功能,尤其是對微細/黏(nian)性/高比電阻(zu)粉(fen)(fen)塵(chen)、氣(qi)溶膠(jiao)、細小的金屬顆(ke)粒等有理想(xiang)的捕集效果。在(zai)國(guo)內的化工、冶(ye)煉、建材等行業有著多年(nian)成功應(ying)用(yong)的業績,在(zai)國(guo)外(wai)的燃(ran)煤電廠中也有近30年(nian)的應(ying)用(yong)歷史。
系(xi)統(tong)構成(cheng)
1、殼(ke)體(ti):全部用鋼板制作,內部進行防(fang)腐處理,由上氣室、中殼(ke)體(ti)、下氣室等組成。
2、沖洗(xi)系統:由(you)管道、噴嘴、電動閥(fa)門、流量(liang)計、壓(ya)力(li)變送器(qi)、放空閥(fa)、水泵(beng)組(zu)成。
3、絕緣系(xi)統:由絕緣箱、熱風清掃裝(zhuang)置和(he)低壓控制柜組成。
4、陰極系統:由(you)大梁、小梁、吊(diao)桿(gan)、陰ji線、重錘(chui)、高(gao)壓機組等組成。電暈電極為鈦合金(jin)芒刺ji線。
5、陽極系統(tong):陽ji系統(tong)的收(shou)塵裝置采用集束型,組裝并(bing)粘接好后,再(zai)糊制支撐(cheng)法蘭,安裝時通過其支撐(cheng) 法蘭懸(xuan)掛在(zai)殼(ke)體(ti)內的陽ji支撐(cheng)大梁上(shang)。
6、氣(qi)(qi)體(ti)(ti)分布裝(zhuang)置:氣(qi)(qi)體(ti)(ti)由進氣(qi)(qi)口進入電除霧(wu)器,由于截面(mian)積突(tu)然擴大,容易因(yin)渦(wo)流(liu)而造成整個截面(mian) 積上(shang)的氣(qi)(qi)體(ti)(ti)分布不(bu)均,所以(yi)就需要在(zai)下氣(qi)(qi)室設(she)置氣(qi)(qi)體(ti)(ti)分布裝(zhuang)置,氣(qi)(qi)體(ti)(ti)分布板開孔率一般為25% ~ 50%。
7、供(gong)電(dian)(dian)(dian)(dian)(dian)系統:用于靜電(dian)(dian)(dian)(dian)(dian)沉積的高(gao)壓(ya)(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan),主要有二(er)種。一種是(shi)可控(kong)硅移相控(kong)制(zhi)高(gao)壓(ya)(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan), 簡稱可控(kong)硅電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan),它是(shi)一種“電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)源(yuan)(yuan)”,其主控(kong)量是(shi)“電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)”;另_種是(shi)恒(heng)流(liu)高(gao)壓(ya)(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan),簡稱恒(heng)流(liu)源(yuan)(yuan),它是(shi)一種“電(dian)(dian)(dian)(dian)(dian)流(liu)源(yuan)(yuan)”,其主控(kong)量是(shi)“電(dian)(dian)(dian)(dian)(dian)流(liu)”。
產品(pin)用途
隨著國(guo)(guo)民經濟的迅速發(fa)展,環境污(wu)(wu)(wu)(wu)染(ran)和生(sheng)態破壞(huai)日趨(qu)嚴(yan)(yan)重,國(guo)(guo)家對(dui)大氣質量控制越來(lai)越嚴(yan)(yan),對(dui)除塵設備的性(xing)能(neng)(neng)和可靠性(xing)也提(ti)出了(le)嚴(yan)(yan)格的要(yao)(yao)求。濕式(shi)靜電除霧除塵器擁有捕(bu)集煙氣中霧滴(di)、粉(fen)塵和微(wei)小塵粒的強大功(gong)能(neng)(neng),尤其是(shi)對(dui)微(wei)細(xi)/黏性(xing)/高比電阻粉(fen)塵、氣溶膠、細(xi)小的金(jin)屬顆粒等有理想的捕(bu)集效果。在(zai)(zai)國(guo)(guo)內(nei)的化工、冶煉、建材等行業(ye)有著多年成功(gong)應(ying)用的業(ye)績,在(zai)(zai)國(guo)(guo)外的燃煤電廠中也有近30年的應(ying)用歷史(shi)。當前(qian),燃煤機組仍是(shi)我國(guo)(guo)電力(li)行業(ye)的主要(yao)(yao)發(fa)電裝置,是(shi)我國(guo)(guo)大氣污(wu)(wu)(wu)(wu)染(ran)的主要(yao)(yao)來(lai)源之(zhi)一。隨著國(guo)(guo)家對(dui)環保要(yao)(yao)求的進一步(bu)提(ti)高,人們對(dui)燃煤電廠、燒結(jie)機、鍋爐煙氣所排放的微(wei)小污(wu)(wu)(wu)(wu)染(ran)物(wu)、有機污(wu)(wu)(wu)(wu)染(ran)物(wu)、重金(jin)屬的認識不斷加深,對(dui)這些(xie)污(wu)(wu)(wu)(wu)染(ran)物(wu)捕(bu)集的呼聲日益提(ti)高。
