3、絕(jue)(jue)緣系統:由絕(jue)(jue)緣箱、熱風清掃裝置(zhi)和低壓控制(zhi)柜組成。
4、陰極系統:由大(da)梁、小梁、吊桿、陰ji線(xian)(xian)、重錘、高壓機(ji)組等組成(cheng)。電暈電極為(wei)鈦(tai)合金芒刺ji線(xian)(xian)。
5、陽(yang)(yang)極系統:陽(yang)(yang)ji系統的(de)收塵裝(zhuang)置采用(yong)集束型,組裝(zhuang)并粘(zhan)接好(hao)后,再糊制支(zhi)(zhi)撐(cheng)(cheng)法蘭,安裝(zhuang)時通(tong)過其支(zhi)(zhi)撐(cheng)(cheng) 法蘭懸掛在殼體(ti)內的(de)陽(yang)(yang)ji支(zhi)(zhi)撐(cheng)(cheng)大梁上。
6、氣(qi)(qi)體(ti)分布(bu)裝(zhuang)置:氣(qi)(qi)體(ti)由(you)(you)進氣(qi)(qi)口進入電除霧器,由(you)(you)于截面(mian)積(ji)(ji)突然擴(kuo)大(da),容易(yi)因渦流而(er)造成整個(ge)截面(mian) 積(ji)(ji)上的氣(qi)(qi)體(ti)分布(bu)不均,所以(yi)就(jiu)需要(yao)在(zai)下氣(qi)(qi)室設置氣(qi)(qi)體(ti)分布(bu)裝(zhuang)置,氣(qi)(qi)體(ti)分布(bu)板(ban)開孔率一般為25% ~ 50%。
7、供電(dian)(dian)(dian)(dian)(dian)系統(tong):用于靜(jing)電(dian)(dian)(dian)(dian)(dian)沉積的(de)高壓(ya)(ya)直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan),主(zhu)要有(you)二種。一種是(shi)(shi)可(ke)控(kong)(kong)硅移相控(kong)(kong)制高壓(ya)(ya)直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan), 簡稱可(ke)控(kong)(kong)硅電(dian)(dian)(dian)(dian)(dian)源(yuan),它是(shi)(shi)一種“電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)源(yuan)”,其主(zhu)控(kong)(kong)量是(shi)(shi)“電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)”;另_種是(shi)(shi)恒流(liu)(liu)(liu)高壓(ya)(ya)直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan),簡稱恒流(liu)(liu)(liu)源(yuan),它是(shi)(shi)一種“電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)源(yuan)”,其主(zhu)控(kong)(kong)量是(shi)(shi)“電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)”。
產品用途
隨著(zhu)國(guo)民經(jing)濟的(de)(de)迅速發展,環境(jing)污染(ran)和(he)生態破壞(huai)日(ri)(ri)趨嚴重,國(guo)家(jia)對大氣(qi)質量控(kong)制越來越嚴,對除塵設(she)備的(de)(de)性(xing)能(neng)和(he)可(ke)靠性(xing)也(ye)提(ti)出(chu)了嚴格的(de)(de)要(yao)求(qiu)。濕式靜電(dian)(dian)除霧(wu)除塵器擁有(you)捕集(ji)煙(yan)氣(qi)中(zhong)霧(wu)滴、粉塵和(he)微(wei)小塵粒的(de)(de)強大功(gong)能(neng),尤(you)其是(shi)對微(wei)細/黏性(xing)/高比電(dian)(dian)阻(zu)粉塵、氣(qi)溶膠、細小的(de)(de)金屬顆(ke)粒等(deng)有(you)理想的(de)(de)捕集(ji)效果。在國(guo)內(nei)的(de)(de)化工、冶煉、建材等(deng)行(xing)業(ye)有(you)著(zhu)多(duo)年(nian)(nian)成功(gong)應用的(de)(de)業(ye)績(ji),在國(guo)外(wai)的(de)(de)燃煤電(dian)(dian)廠中(zhong)也(ye)有(you)近30年(nian)(nian)的(de)(de)應用歷(li)史(shi)。當前,燃煤機組(zu)仍(reng)是(shi)我國(guo)電(dian)(dian)力行(xing)業(ye)的(de)(de)主(zhu)要(yao)發電(dian)(dian)裝置,是(shi)我國(guo)大氣(qi)污染(ran)的(de)(de)主(zhu)要(yao)來源(yuan)之一(yi)。隨著(zhu)國(guo)家(jia)對環保要(yao)求(qiu)的(de)(de)進一(yi)步(bu)提(ti)高,人們(men)對燃煤電(dian)(dian)廠、燒結機、鍋(guo)爐煙(yan)氣(qi)所(suo)排放的(de)(de)微(wei)小污染(ran)物(wu)、有(you)機污染(ran)物(wu)、重金屬的(de)(de)認識不斷(duan)加深,對這些污染(ran)物(wu)捕集(ji)的(de)(de)呼(hu)聲日(ri)(ri)益提(ti)高。
