將煙塵(chen)(chen)分離出來(lai)的(de)(de)(de)設備稱為除(chu)塵(chen)(chen)器或除(chu)塵(chen)(chen)裝置.除(chu)塵(chen)(chen)器的(de)(de)(de)性能表現為可以處理的(de)(de)(de)氣(qi)體量、氣(qi)體通(tong)過(guo)除(chu)塵(chen)(chen)器的(de)(de)(de)阻力損失和除(chu)塵(chen)(chen)效率(lv).同時,除(chu)塵(chen)(chen)器的(de)(de)(de)價格、運(yun)行維護費(fei)用、使用壽命、運(yun)行管(guan)理難度也是影響其性能的(de)(de)(de)重(zhong)要因素.隨著工業(ye)的(de)(de)(de)發展,除(chu)塵(chen)(chen)器變得越來(lai)越重(zhong)要.

    目前最常用的除(chu)塵(chen)(chen)器(qi)(qi)(qi)有:重(zhong)力除(chu)塵(chen)(chen)器(qi)(qi)(qi)、慣性除(chu)塵(chen)(chen)器(qi)(qi)(qi)、離心式(shi)(shi)除(chu)塵(chen)(chen)器(qi)(qi)(qi)等(deng)機械除(chu)塵(chen)(chen)器(qi)(qi)(qi).洗滌器(qi)(qi)(qi)集塵(chen)(chen)器(qi)(qi)(qi)包括水(shui)浴式(shi)(shi)除(chu)塵(chen)(chen)器(qi)(qi)(qi)、氣泡式(shi)(shi)除(chu)塵(chen)(chen)器(qi)(qi)(qi)、文丘(qiu)里管除(chu)塵(chen)(chen)器(qi)(qi)(qi)、水(shui)膜(mo)式(shi)(shi)除(chu)塵(chen)(chen)器(qi)(qi)(qi)等(deng).靜電除(chu)塵(chen)(chen)器(qi)(qi)(qi)、磁力除(chu)塵(chen)(chen)器(qi)(qi)(qi).

    靜(jing)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)是工業中應(ying)用最廣泛、應(ying)用最廣泛的(de)(de)一種.靜(jing)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)在市場上有什(shen)么優勢(shi)?過濾除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)靜(jing)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)制造商簡單地解釋為每個人的(de)(de)優點:靜(jing)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)的(de)(de)工作原理是高壓電(dian)(dian)(dian)(dian)場電(dian)(dian)(dian)(dian)離煙氣中使(shi)用,空氣流(liu)中的(de)(de)帶電(dian)(dian)(dian)(dian)粉塵(chen)(chen)在電(dian)(dian)(dian)(dian)場作用和流(liu)動(dong)分離.陰極由不(bu)同截面的(de)(de)金屬絲(si)制成,稱為放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極.正極是由不(bu)同幾何形狀的(de)(de)金屬板制成的(de)(de),稱為集塵(chen)(chen)電(dian)(dian)(dian)(dian)極.

    靜(jing)電除(chu)塵器(qi)(qi)的(de)性(xing)能(neng)受(shou)粉(fen)塵特性(xing)、設備結構(gou)和(he)(he)煙氣流速三個因(yin)素的(de)影(ying)響.粉(fen)塵的(de)電阻(zu)率(lv)是電導(dao)率(lv)的(de)指標(biao),它(ta)直(zhi)接影(ying)響除(chu)塵效(xiao)率(lv).低于阻(zu)力(li),灰塵顆粒(li)不能(neng)保持在集塵器(qi)(qi)上,導(dao)致(zhi)(zhi)它(ta)回到(dao)空氣中.比電阻(zu)高,除(chu)塵器(qi)(qi)上的(de)粉(fen)塵顆粒(li)不易釋放,粉(fen)塵層間的(de)電壓(ya)梯(ti)度會產(chan)生局部(bu)擊穿(chuan)和(he)(he)放電.這(zhe)些條(tiao)件會導(dao)致(zhi)(zhi)除(chu)塵效(xiao)率(lv)下(xia)降.

    靜電除(chu)(chu)塵(chen)器的電源由(you)控制(zhi)箱、升壓(ya)(ya)變壓(ya)(ya)器和整(zheng)流器組成(cheng).電源輸出電壓(ya)(ya)對除(chu)(chu)塵(chen)效率(lv)也有很大影響.因此(ci),靜電除(chu)(chu)塵(chen)器運行(xing)電壓(ya)(ya)應保持(chi)40以上(shang),75kv 100kv.與其他除(chu)(chu)塵(chen)設(she)備(bei)相比(bi),電除(chu)(chu)塵(chen)器能(neng)耗小,除(chu)(chu)塵(chen),適用于煙氣中0的除(chu)(chu)塵(chen).01~50μm粉塵(chen),可用于高溫高壓(ya)(ya)煙氣.實踐證明,氣體體積越大,電除(chu)(chu)塵(chen)器的投(tou)資和運行(xing)費(fei)用越經濟.
