系統構成(cheng)
1、殼體:全部用鋼板制作,內部進行防(fang)腐處理,由上氣室(shi)、中殼體、下(xia)氣室(shi)等組(zu)成。
2、沖洗系統:由管道、噴嘴、電動閥(fa)門、流量計、壓(ya)力(li)變送器、放空閥(fa)、水(shui)泵(beng)組成(cheng)。
3、絕緣(yuan)系統(tong):由絕緣(yuan)箱、熱風清掃裝(zhuang)置和低(di)壓控制柜組成。
4、陰極系(xi)統:由大梁、小梁、吊桿(gan)、陰ji線、重錘、高(gao)壓(ya)機組(zu)(zu)等組(zu)(zu)成。電(dian)暈電(dian)極為(wei)鈦(tai)合金芒(mang)刺(ci)ji線。
5、陽(yang)(yang)極系統(tong):陽(yang)(yang)ji系統(tong)的收(shou)塵裝置采用集束型,組裝并粘接好(hao)后,再糊(hu)制支撐法蘭,安裝時(shi)通過其(qi)支撐 法蘭懸掛在殼體(ti)內的陽(yang)(yang)ji支撐大梁上。
6、氣體(ti)(ti)分(fen)(fen)布(bu)裝置:氣體(ti)(ti)由進氣口進入電除霧(wu)器,由于(yu)截面積(ji)突然擴大,容易(yi)因渦流而造成(cheng)整個(ge)截面 積(ji)上的氣體(ti)(ti)分(fen)(fen)布(bu)不均(jun),所以就需要(yao)在下氣室設置氣體(ti)(ti)分(fen)(fen)布(bu)裝置,氣體(ti)(ti)分(fen)(fen)布(bu)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(chen)積(ji)的高壓(ya)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan),主要(yao)有二種(zhong)。一(yi)種(zhong)是(shi)可控(kong)(kong)硅移相控(kong)(kong)制高壓(ya)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan), 簡稱(cheng)可控(kong)(kong)硅電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan),它(ta)是(shi)一(yi)種(zhong)“電(dian)(dian)(dian)(dian)(dian)壓(ya)源(yuan)(yuan)”,其(qi)主控(kong)(kong)量(liang)是(shi)“電(dian)(dian)(dian)(dian)(dian)壓(ya)”;另一(yi)種(zhong)是(shi)恒流(liu)高壓(ya)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan),簡稱(cheng)恒流(liu)源(yuan)(yuan),它(ta)是(shi)一(yi)種(zhong)“電(dian)(dian)(dian)(dian)(dian)流(liu)源(yuan)(yuan)”,其(qi)主控(kong)(kong)量(liang)是(shi)“電(dian)(dian)(dian)(dian)(dian)流(liu)”。
