系統(tong)構成(cheng)
1、殼體:全(quan)部(bu)用鋼板(ban)制作,內部(bu)進行防腐(fu)處(chu)理(li),由上氣(qi)室、中(zhong)殼體、下(xia)氣(qi)室等組成。
2、沖(chong)洗(xi)系統:由管(guan)道、噴嘴、電動閥門、流量計、壓力變送器、放空閥、水泵組成(cheng)。
3、絕緣系統(tong):由絕緣箱、熱(re)風清掃(sao)裝置和低壓控制柜組成。
4、陰(yin)極(ji)系統(tong):由大梁(liang)、小梁(liang)、吊桿、陰(yin)ji線、重錘(chui)、高(gao)壓機組等組成。電暈電極(ji)為鈦合金芒刺(ci)ji線。
5、陽極系(xi)統:陽ji系(xi)統的收(shou)塵(chen)裝置采用(yong)集束型,組(zu)裝并粘接好后,再糊制支撐(cheng)(cheng)法(fa)蘭,安裝時通過(guo)其支撐(cheng)(cheng) 法(fa)蘭懸掛在殼體內的陽ji支撐(cheng)(cheng)大(da)梁上。
6、氣(qi)(qi)體(ti)分布(bu)裝(zhuang)置:氣(qi)(qi)體(ti)由(you)(you)進(jin)氣(qi)(qi)口進(jin)入(ru)電除(chu)霧器,由(you)(you)于截面積突然(ran)擴大,容易因渦流而造成整個截面 積上的氣(qi)(qi)體(ti)分布(bu)不均,所以就需要在下(xia)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)板開孔率(lv)一般為25% ~ 50%。
7、供電(dian)(dian)(dian)系(xi)統:用于靜電(dian)(dian)(dian)沉積的高壓(ya)(ya)(ya)直流(liu)電(dian)(dian)(dian)源,主要有(you)二種(zhong)(zhong)(zhong)。一種(zhong)(zhong)(zhong)是(shi)(shi)可控(kong)(kong)(kong)硅(gui)移相(xiang)控(kong)(kong)(kong)制高壓(ya)(ya)(ya)直流(liu)電(dian)(dian)(dian)源, 簡(jian)(jian)稱可控(kong)(kong)(kong)硅(gui)電(dian)(dian)(dian)源,它是(shi)(shi)一種(zhong)(zhong)(zhong)“電(dian)(dian)(dian)壓(ya)(ya)(ya)源”,其(qi)主控(kong)(kong)(kong)量是(shi)(shi)“電(dian)(dian)(dian)壓(ya)(ya)(ya)”;另_種(zhong)(zhong)(zhong)是(shi)(shi)恒流(liu)高壓(ya)(ya)(ya)直流(liu)電(dian)(dian)(dian)源,簡(jian)(jian)稱恒流(liu)源,它是(shi)(shi)一種(zhong)(zhong)(zhong)“電(dian)(dian)(dian)流(liu)源”,其(qi)主控(kong)(kong)(kong)量是(shi)(shi)“電(dian)(dian)(dian)流(liu)”。
產(chan)品用途
隨著國民經濟的迅速發展,環(huan)境污(wu)染和生態破壞日(ri)趨嚴重(zhong),國家對大氣(qi)(qi)(qi)質(zhi)量(liang)控制越(yue)(yue)來(lai)越(yue)(yue)嚴,對除塵(chen)(chen)設備的性(xing)能和可靠性(xing)也(ye)提出了嚴格(ge)的要(yao)求。濕(shi)式(shi)靜電(dian)除霧除塵(chen)(chen)器擁有捕(bu)集煙氣(qi)(qi)(qi)中(zhong)霧滴、粉塵(chen)(chen)和微(wei)小塵(chen)(chen)粒的強(qiang)大功能,尤(you)其是對微(wei)細(xi)/黏性(xing)/高(gao)比電(dian)阻粉塵(chen)(chen)、氣(qi)(qi)(qi)溶膠、細(xi)小的金屬(shu)顆(ke)粒等有理(li)想(xiang)的捕(bu)集效(xiao)果。在國內的化工、冶煉、建材等行(xing)業有著多年(nian)成(cheng)功應用(yong)的業績,在國外的燃(ran)(ran)煤(mei)電(dian)廠(chang)中(zhong)也(ye)有近30年(nian)的應用(yong)歷史。當前,燃(ran)(ran)煤(mei)機(ji)(ji)組仍是我國電(dian)力行(xing)業的主要(yao)發電(dian)裝置,是我國大氣(qi)(qi)(qi)污(wu)染的主要(yao)來(lai)源(yuan)之一。隨著國家對環(huan)保要(yao)求的進一步提高(gao),人(ren)們對燃(ran)(ran)煤(mei)電(dian)廠(chang)、燒結機(ji)(ji)、鍋爐煙氣(qi)(qi)(qi)所排放的微(wei)小污(wu)染物(wu)、有機(ji)(ji)污(wu)染物(wu)、重(zhong)金屬(shu)的認識不(bu)斷加深,對這些污(wu)染物(wu)捕(bu)集的呼(hu)聲日(ri)益提高(gao)。
