CJMA、CJMB型高(gao)壓靜電(dian)管式收(shou)塵器(qi)工作原理：

利用(yong)高(gao)壓(ya)電(dian)(dian)(dian)(dian)場使煙氣(qi)(qi)發(fa)生(sheng)電(dian)(dian)(dian)(dian)離(li)(li)，氣(qi)(qi)流(liu)中的(de)(de)(de)粉(fen)塵(chen)荷(he)電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作用(yong)下(xia)與氣(qi)(qi)流(liu)分(fen)離(li)(li)。負極由不(bu)同(tong)斷面形(xing)(xing)狀的(de)(de)(de)金屬(shu)導線制成，叫(jiao)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由不(bu)同(tong)幾(ji)何形(xing)(xing)狀的(de)(de)(de)金屬(shu)板制成，叫(jiao)集(ji)塵(chen)電(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)的(de)(de)(de)性能受粉(fen)塵(chen)性質、設備構(gou)造(zao)和煙氣(qi)(qi)流(liu)速等三個(ge)因素的(de)(de)(de)影響。粉(fen)塵(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)(dian)性的(de)(de)(de)指(zhi)標，它對除(chu)塵(chen)效率有直接的(de)(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)粒難以保持在集(ji)塵(chen)電(dian)(dian)(dian)(dian)極上，致使其重返氣(qi)(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過(guo)高(gao)，到達集(ji)塵(chen)電(dian)(dian)(dian)(dian)極的(de)(de)(de)塵(chen)粒電(dian)(dian)(dian)(dian)荷(he)不(bu)易放出，在塵(chen)層之間形(xing)(xing)成電(dian)(dian)(dian)(dian)壓(ya)梯度會產(chan)生(sheng)局(ju)部擊穿和放電(dian)(dian)(dian)(dian)現象。這些情況都(dou)會造(zao)成除(chu)塵(chen)效率下(xia)降。

1、優化的結構設計

在除塵(chen)器(qi)(qi)結構(gou)設計上，充(chong)分了(le)(le)(le)(le)考慮了(le)(le)(le)(le)粉塵(chen)慣性力(li)、離(li)心力(li)、反靜電(dian)(dian)力(li)。二(er)次揚塵(chen)以及供電(dian)(dian)電(dian)(dian)源(yuan)的波形性能、工作特點等(deng)因素的影響，采用(yong)優化的結構(gou)形式，   大(da)限度(du)的提(ti)(ti)高遷移(yi)速度(du)，從而(er)提(ti)(ti)高了(le)(le)(le)(le)除塵(chen)效率。在處(chu)理同(tong)等(deng)塵(chen)源(yuan)的情況下，收塵(chen)面積(ji)可大(da)幅度(du)下降，即除塵(chen)器(qi)(qi)的尺寸和剛才(cai)消耗減少(shao)。這種小空間(jian)、低成(cheng)本、   設計，為改造舊除塵(chen)設備提(ti)(ti)供了(le)(le)(le)(le)非常有利的條件。

2、   的供電電源

在(zai)(zai)除(chu)(chu)塵供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)設(she)計上與常規(gui)不(bu)同(tong)。他(ta)采用的(de)是軟特(te)性的(de)穩定(ding)(ding)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)。穩定(ding)(ding)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓比脈動直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓優越。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)工作(zuo)的(de)   佳點是在(zai)(zai)火花(hua)始發以下臨界(jie)處。在(zai)(zai)設(she)計上，把電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)整個(ge)過(guo)程夠控(kong)制(zhi)在(zai)(zai)火花(hua)始發點以下的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)狀態。不(bu)讓其進入火花(hua)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)狀態。火花(hua)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)實質上是正(zheng)、負離子在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場中發生(sheng)碰中釋(shi)放能力(li)的(de)一種(zhong)現象，它(ta)對除(chu)(chu)塵毫無作(zuo)用。常規(gui)靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵器在(zai)(zai)整個(ge)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)過(guo)程中，包含了火花(hua)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)和(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，并且絕大部分能量都在(zai)(zai)屬于火花(hua)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)被浪費掉了。而本(ben)技術在(zai)(zai)處理同(tong)等塵源(yuan)(yuan)的(de)情況下，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場耗能不(bu)足(zu)常規(gui)靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵器的(de)之(zhi)一。
