系統構成
1、殼體:全部用(yong)鋼板(ban)制作(zuo),內部進行(xing)防(fang)腐處理,由(you)上氣室(shi)、中殼體、下氣室(shi)等組成。
2、沖洗系統:由管道(dao)、噴嘴(zui)、電動閥門(men)、流量計、壓力變送器、放(fang)空閥、水泵組成。
3、絕緣系統:由絕緣箱、熱風清掃裝置(zhi)和(he)低壓控制柜組成。
4、陰(yin)極系統(tong):由大梁(liang)、小梁(liang)、吊桿、陰(yin)ji線、重(zhong)錘(chui)、高壓機組等組成。電(dian)暈電(dian)極為鈦合金芒刺ji線。
5、陽(yang)極系統(tong):陽(yang)ji系統(tong)的收塵裝(zhuang)(zhuang)置(zhi)采(cai)用(yong)集束型,組裝(zhuang)(zhuang)并(bing)粘接好后,再糊制支撐法蘭(lan),安裝(zhuang)(zhuang)時通過其支撐 法蘭(lan)懸掛在殼體(ti)內的陽(yang)ji支撐大梁上。
6、氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)分布裝(zhuang)置(zhi):氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)由進氣(qi)(qi)(qi)(qi)(qi)口進入電除霧器,由于(yu)截(jie)面積突(tu)然擴大,容易因渦流而造成整(zheng)個截(jie)面 積上(shang)的(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)分布不均(jun),所以(yi)就(jiu)需要在下氣(qi)(qi)(qi)(qi)(qi)室設置(zhi)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)分布裝(zhuang)置(zhi),氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)分布板開孔率一般(ban)為25% ~ 50%。
7、供電(dian)(dian)(dian)(dian)(dian)系統:用于靜電(dian)(dian)(dian)(dian)(dian)沉積的(de)高壓(ya)直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan),主要有二(er)種(zhong)(zhong)。一種(zhong)(zhong)是(shi)可(ke)控(kong)(kong)硅移相控(kong)(kong)制高壓(ya)直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan), 簡稱(cheng)可(ke)控(kong)(kong)硅電(dian)(dian)(dian)(dian)(dian)源(yuan),它(ta)是(shi)一種(zhong)(zhong)“電(dian)(dian)(dian)(dian)(dian)壓(ya)源(yuan)”,其(qi)主控(kong)(kong)量是(shi)“電(dian)(dian)(dian)(dian)(dian)壓(ya)”;另_種(zhong)(zhong)是(shi)恒流(liu)(liu)(liu)高壓(ya)直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan),簡稱(cheng)恒流(liu)(liu)(liu)源(yuan),它(ta)是(shi)一種(zhong)(zhong)“電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)源(yuan)”,其(qi)主控(kong)(kong)量是(shi)“電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)”。
產品(pin)用途
隨(sui)(sui)著(zhu)(zhu)國民經濟的(de)迅速發展,環(huan)境污(wu)染和(he)生態破壞(huai)日趨嚴重,國家對(dui)(dui)(dui)大(da)氣質量控制越來越嚴,對(dui)(dui)(dui)除塵(chen)(chen)設備的(de)性(xing)(xing)能和(he)可靠性(xing)(xing)也(ye)提(ti)出了嚴格的(de)要求。濕式(shi)靜電(dian)(dian)除霧(wu)除塵(chen)(chen)器擁有(you)捕集煙氣中霧(wu)滴、粉塵(chen)(chen)和(he)微(wei)小(xiao)塵(chen)(chen)粒(li)的(de)強大(da)功(gong)能,尤其是對(dui)(dui)(dui)微(wei)細/黏性(xing)(xing)/高比電(dian)(dian)阻粉塵(chen)(chen)、氣溶膠、細小(xiao)的(de)金屬顆粒(li)等有(you)理想(xiang)的(de)捕集效果。在(zai)國內的(de)化工(gong)、冶煉(lian)、建材等行業有(you)著(zhu)(zhu)多年成(cheng)功(gong)應用的(de)業績,在(zai)國外的(de)燃煤(mei)電(dian)(dian)廠中也(ye)有(you)近(jin)30年的(de)應用歷(li)史。當前,燃煤(mei)機組仍是我國電(dian)(dian)力行業的(de)主(zhu)要發電(dian)(dian)裝置(zhi),是我國大(da)氣污(wu)染的(de)主(zhu)要來源之一(yi)。隨(sui)(sui)著(zhu)(zhu)國家對(dui)(dui)(dui)環(huan)保(bao)要求的(de)進(jin)一(yi)步(bu)提(ti)高,人們對(dui)(dui)(dui)燃煤(mei)電(dian)(dian)廠、燒結機、鍋爐煙氣所排放的(de)微(wei)小(xiao)污(wu)染物、有(you)機污(wu)染物、重金屬的(de)認識不斷加深,對(dui)(dui)(dui)這些污(wu)染物捕集的(de)呼(hu)聲日益(yi)提(ti)高。
