;高壓(ya)靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的運作原理(li)是(shi)(shi)采用高壓(ya)電(dian)(dian)(dian)(dian)場使(shi)霧氣(qi)(qi)(qi)游離(li)顆粒(li)產(chan)生電(dian)(dian)(dian)(dian)荷(he)不(bu)穩定，大(da)氣(qi)(qi)(qi)中的灰塵(chen)(chen)(chen)顆粒(li)荷(he)電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場影響(xiang)下和空(kong)氣(qi)(qi)(qi)分開。-極(ji)是(shi)(shi)不(bu)同斷(duan)面(mian)形(xing)狀(zhuang)的導(dao)(dao)電(dian)(dian)(dian)(dian)金屬(shu)線做的，這(zhe)(zhe)是(shi)(shi)放(fang)(fang)電(dian)(dian)(dian)(dian)的那個電(dian)(dian)(dian)(dian)極(ji)。+極(ji)是(shi)(shi)不(bu)同幾何形(xing)狀(zhuang)的導(dao)(dao)電(dian)(dian)(dian)(dian)板做的，這(zhe)(zhe)是(shi)(shi)聚塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的效率受(shou)霧氣(qi)(qi)(qi)顆粒(li)屬(shu)性、設備結構和霧氣(qi)(qi)(qi)流(liu)速這(zhe)(zhe)三大(da)因素(su)的控制。粉塵(chen)(chen)(chen)的電(dian)(dian)(dian)(dian)阻比是(shi)(shi)判斷(duan)導(dao)(dao)電(dian)(dian)(dian)(dian)性的標準，直接(jie)影響(xiang)除塵(chen)(chen)(chen)效果。電(dian)(dian)(dian)(dian)阻比太低(di)，顆粒(li)很難附(fu)著在聚塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上(shang)，這(zhe)(zhe)樣它(ta)們(men)就會(hui)(hui)重新(xin)回到霧氣(qi)(qi)(qi)中。電(dian)(dian)(dian)(dian)阻比太高，聚塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上(shang)面(mian)的顆粒(li)電(dian)(dian)(dian)(dian)荷(he)越(yue)聚越(yue)多，在顆粒(li)層之間形(xing)成電(dian)(dian)(dian)(dian)壓(ya)梯度會(hui)(hui)產(chan)生局部擊(ji)穿和放(fang)(fang)電(dian)(dian)(dian)(dian)現(xian)象。這(zhe)(zhe)些原因會(hui)(hui)使(shi)設備工作效果下降(jiang)。

靜(jing)(jing)電(dian)(dian)(dian)(dian)除塵器的(de)電(dian)(dian)(dian)(dian)源由控制箱、升壓(ya)(ya)變壓(ya)(ya)器和整流(liu)器組成(cheng)。電(dian)(dian)(dian)(dian)源輸出的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)高低對除塵效率也有很大(da)(da)影響。因(yin)此，靜(jing)(jing)電(dian)(dian)(dian)(dian)除塵器運行電(dian)(dian)(dian)(dian)壓(ya)(ya)需保持40一75kV乃(nai)至100kV以(yi)上。靜(jing)(jing)電(dian)(dian)(dian)(dian)除塵器[2]  與其他除塵設(she)備(bei)相比，耗能(neng)少，除塵效率高，適用(yong)(yong)于除去煙(yan)氣中(zhong)0．01—50μm的(de)粉塵，而且可用(yong)(yong)于煙(yan)氣溫度高、壓(ya)(ya)力大(da)(da)的(de)場(chang)合。實踐(jian)表明，處理的(de)煙(yan)氣量越大(da)(da)，使用(yong)(yong)靜(jing)(jing)電(dian)(dian)(dian)(dian)除塵器的(de)投資和運行費用(yong)(yong)越經濟。
