烘干機高壓靜電除塵(chen)器(qi)工(gong)作原理(li)：

利用高壓電(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)(qi)發(fa)生(sheng)電(dian)(dian)(dian)(dian)離，氣(qi)(qi)流(liu)(liu)中的粉(fen)(fen)塵(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作用下與氣(qi)(qi)流(liu)(liu)分(fen)離。負(fu)極(ji)(ji)由不(bu)(bu)同斷面形狀(zhuang)的金(jin)屬(shu)導線制(zhi)成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)(bu)同幾(ji)何(he)形狀(zhuang)的金(jin)屬(shu)板制(zhi)成(cheng)，叫集(ji)塵(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)除塵(chen)器(qi)的性能受(shou)粉(fen)(fen)塵(chen)性質、設備構(gou)造(zao)和(he)煙氣(qi)(qi)流(liu)(liu)速等三個因素(su)的影響。粉(fen)(fen)塵(chen)的比電(dian)(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)(dian)性的指標，它(ta)對(dui)除塵(chen)效率有直接的影響。比電(dian)(dian)(dian)(dian)阻過低，塵(chen)粒(li)(li)難以保(bao)持在集(ji)塵(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，致使(shi)其重(zhong)返氣(qi)(qi)流(liu)(liu)。比電(dian)(dian)(dian)(dian)阻過高，到(dao)達(da)集(ji)塵(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的塵(chen)粒(li)(li)電(dian)(dian)(dian)(dian)荷不(bu)(bu)易放(fang)出(chu)，在塵(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局(ju)部擊(ji)穿和(he)放(fang)電(dian)(dian)(dian)(dian)現象。這些情況都會造(zao)成(cheng)除塵(chen)效率下降。

1、優化的結構設計

在(zai)除(chu)塵(chen)(chen)(chen)器結構設(she)計上，充分(fen)了考慮了粉(fen)塵(chen)(chen)(chen)慣性力、離(li)心力、反靜電(dian)力。二(er)次揚塵(chen)(chen)(chen)以及供電(dian)電(dian)源(yuan)的(de)波形性能、工作(zuo)特點等因(yin)素(su)的(de)影響，采(cai)用優(you)化(hua)的(de)結構形式，   大(da)限度(du)的(de)提(ti)(ti)高(gao)遷移速度(du)，從而提(ti)(ti)高(gao)了除(chu)塵(chen)(chen)(chen)效率。在(zai)處理同等塵(chen)(chen)(chen)源(yuan)的(de)情況(kuang)下，收塵(chen)(chen)(chen)面積可大(da)幅(fu)度(du)下降，即(ji)除(chu)塵(chen)(chen)(chen)器的(de)尺寸和剛才(cai)消(xiao)耗(hao)減少。這(zhe)種小空間、低(di)成本、   率設(she)計，為改(gai)造舊(jiu)除(chu)塵(chen)(chen)(chen)設(she)備提(ti)(ti)供了非常有利的(de)條件。

2、   的(de)供電電源

在(zai)(zai)(zai)除塵(chen)(chen)供電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)源設(she)計上與常(chang)(chang)規不(bu)同(tong)。他采用的(de)是軟特性的(de)穩定直(zhi)流電(dian)(dian)(dian)(dian)(dian)源。穩定直(zhi)流電(dian)(dian)(dian)(dian)(dian)壓比脈(mo)動直(zhi)流電(dian)(dian)(dian)(dian)(dian)壓優越。電(dian)(dian)(dian)(dian)(dian)源工(gong)作(zuo)的(de)   佳點(dian)(dian)是在(zai)(zai)(zai)火(huo)花(hua)始(shi)發以下臨界(jie)處。在(zai)(zai)(zai)設(she)計上，把電(dian)(dian)(dian)(dian)(dian)源供電(dian)(dian)(dian)(dian)(dian)整個(ge)過(guo)程(cheng)夠(gou)控制在(zai)(zai)(zai)火(huo)花(hua)始(shi)發點(dian)(dian)以下的(de)電(dian)(dian)(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)(dian)(dian)狀態。不(bu)讓其進入火(huo)花(hua)放(fang)電(dian)(dian)(dian)(dian)(dian)狀態。火(huo)花(hua)放(fang)電(dian)(dian)(dian)(dian)(dian)實質(zhi)上是正、負離子在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場中(zhong)發生碰中(zhong)釋放(fang)能(neng)力的(de)一種現象，它(ta)對除塵(chen)(chen)毫無作(zuo)用。常(chang)(chang)規靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器在(zai)(zai)(zai)整個(ge)供電(dian)(dian)(dian)(dian)(dian)過(guo)程(cheng)中(zhong)，包(bao)含了火(huo)花(hua)放(fang)電(dian)(dian)(dian)(dian)(dian)和(he)電(dian)(dian)(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)(dian)(dian)，并且絕(jue)大部(bu)分(fen)能(neng)量都在(zai)(zai)(zai)屬于火(huo)花(hua)電(dian)(dian)(dian)(dian)(dian)被(bei)浪(lang)費掉了。而本技(ji)術在(zai)(zai)(zai)處理同(tong)等塵(chen)(chen)源的(de)情況(kuang)下，電(dian)(dian)(dian)(dian)(dian)場耗能(neng)不(bu)足常(chang)(chang)規靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)之一。
