系統(tong)構成(cheng)
1、殼體(ti):全部用鋼板(ban)制作(zuo),內部進行防腐處理,由上氣室、中殼體(ti)、下氣室等組成。
2、沖洗系統:由管道、噴嘴、電動閥門、流量計、壓(ya)力(li)變送(song)器、放空閥、水(shui)泵(beng)組(zu)成。
3、絕緣系統:由絕緣箱、熱風清掃裝置(zhi)和低壓控制(zhi)柜組成。
4、陰(yin)極系統:由大梁、小梁、吊桿、陰(yin)ji線、重(zhong)錘、高壓機組等組成(cheng)。電暈(yun)電極為(wei)鈦合(he)金芒刺ji線。
5、陽極系統:陽ji系統的收塵(chen)裝置采用集束型,組裝并粘接好后,再糊(hu)制支撐(cheng)法(fa)蘭,安裝時通過(guo)其支撐(cheng) 法(fa)蘭懸掛在殼體(ti)(ti)內的陽ji支撐(cheng)大梁(liang)上。
6、氣體(ti)分布(bu)(bu)裝置(zhi):氣體(ti)由進氣口進入電(dian)除霧器(qi),由于(yu)截(jie)面積(ji)突然擴大(da),容易因(yin)渦流而造成(cheng)整(zheng)個(ge)截(jie)面 積(ji)上的氣體(ti)分布(bu)(bu)不均,所以就需要在下氣室(shi)設置(zhi)氣體(ti)分布(bu)(bu)裝置(zhi),氣體(ti)分布(bu)(bu)板開孔率一(yi)般為25% ~ 50%。
7、供電(dian)(dian)(dian)(dian)系統(tong):用于靜電(dian)(dian)(dian)(dian)沉積的高(gao)壓(ya)直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan),主(zhu)(zhu)要有(you)二(er)種。一種是可控(kong)(kong)硅移(yi)相控(kong)(kong)制高(gao)壓(ya)直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan), 簡(jian)稱可控(kong)(kong)硅電(dian)(dian)(dian)(dian)源(yuan)(yuan),它是一種“電(dian)(dian)(dian)(dian)壓(ya)源(yuan)(yuan)”,其主(zhu)(zhu)控(kong)(kong)量是“電(dian)(dian)(dian)(dian)壓(ya)”;另一種是恒流(liu)(liu)(liu)高(gao)壓(ya)直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan),簡(jian)稱恒流(liu)(liu)(liu)源(yuan)(yuan),它是一種“電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)源(yuan)(yuan)”,其主(zhu)(zhu)控(kong)(kong)量是“電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)”。
產品用途
隨著國(guo)(guo)民經濟的(de)(de)迅速(su)發(fa)展(zhan),環境污(wu)(wu)(wu)(wu)染(ran)(ran)(ran)和(he)生態破壞日趨嚴(yan)(yan)重(zhong),國(guo)(guo)家(jia)(jia)對(dui)(dui)大(da)氣質量控(kong)制(zhi)越(yue)來越(yue)嚴(yan)(yan),對(dui)(dui)除塵(chen)(chen)(chen)設備(bei)的(de)(de)性能和(he)可(ke)靠性也(ye)提出了(le)嚴(yan)(yan)格的(de)(de)要(yao)(yao)求。濕式靜電(dian)(dian)(dian)除霧(wu)(wu)除塵(chen)(chen)(chen)器擁(yong)有捕集煙氣中霧(wu)(wu)滴(di)、粉塵(chen)(chen)(chen)和(he)微小(xiao)塵(chen)(chen)(chen)粒的(de)(de)強大(da)功能,尤(you)其是對(dui)(dui)微細(xi)/黏(nian)性/高比(bi)電(dian)(dian)(dian)阻粉塵(chen)(chen)(chen)、氣溶膠、細(xi)小(xiao)的(de)(de)金屬顆粒等(deng)有理想的(de)(de)捕集效果。在國(guo)(guo)內的(de)(de)化工(gong)、冶(ye)煉、建材等(deng)行業有著多年成功應用的(de)(de)業績(ji),在國(guo)(guo)外的(de)(de)燃煤(mei)電(dian)(dian)(dian)廠中也(ye)有近30年的(de)(de)應用歷(li)史。當前(qian),燃煤(mei)機(ji)組仍是我(wo)國(guo)(guo)電(dian)(dian)(dian)力(li)行業的(de)(de)主(zhu)要(yao)(yao)發(fa)電(dian)(dian)(dian)裝置,是我(wo)國(guo)(guo)大(da)氣污(wu)(wu)(wu)(wu)染(ran)(ran)(ran)的(de)(de)主(zhu)要(yao)(yao)來源之一(yi)。隨著國(guo)(guo)家(jia)(jia)對(dui)(dui)環保(bao)要(yao)(yao)求的(de)(de)進一(yi)步提高,人們對(dui)(dui)燃煤(mei)電(dian)(dian)(dian)廠、燒結機(ji)、鍋爐煙氣所排(pai)放的(de)(de)微小(xiao)污(wu)(wu)(wu)(wu)染(ran)(ran)(ran)物、有機(ji)污(wu)(wu)(wu)(wu)染(ran)(ran)(ran)物、重(zhong)金屬的(de)(de)認識不斷加深(shen),對(dui)(dui)這些污(wu)(wu)(wu)(wu)染(ran)(ran)(ran)物捕集的(de)(de)呼(hu)聲日益提高。
