CDG型高壓靜(jing)電除塵器的除塵原理：

CDG型(xing)高(gao)壓靜電(dian)(dian)(dian)除塵(chen)器(qi)是采用高(gao)壓靜電(dian)(dian)(dian)原理，以靜電(dian)(dian)(dian)凈(jing)(jing)化法(fa)進(jin)行(xing)收(shou)(shou)捕煙(yan)氣(qi)(qi)中粉塵(chen)的(de)裝(zhuang)(zhuang)置(zhi)(zhi)，是凈(jing)(jing)化工業廢氣(qi)(qi)的(de)理想設備，它(ta)的(de)凈(jing)(jing)化工作(zuo)主要依(yi)靠(kao)放電(dian)(dian)(dian)極(ji)(ji)和沉(chen)淀極(ji)(ji)這(zhe)兩個系統來(lai)完(wan)成。當兩極(ji)(ji)間輸入(ru)高(gao)壓直流電(dian)(dian)(dian)時在(zai)電(dian)(dian)(dian)極(ji)(ji)空間，產生(sheng)陰(yin)、陽離(li)子(zi)(zi)，當含塵(chen)氣(qi)(qi)體進(jin)入(ru)電(dian)(dian)(dian)場后(hou)，靜電(dian)(dian)(dian)離(li)子(zi)(zi)作(zuo)用于通(tong)過靜電(dian)(dian)(dian)場的(de)塵(chen)粒表面，塵(chen)粒就與(yu)這(zhe)些電(dian)(dian)(dian)子(zi)(zi)和離(li)子(zi)(zi)結合(he)起來(lai)，在(zai)電(dian)(dian)(dian)場力的(de)作(zuo)用下(xia)向其(qi)極(ji)(ji)性相反(fan)的(de)電(dian)(dian)(dian)極(ji)(ji)移動，后(hou)在(zai)電(dian)(dian)(dian)極(ji)(ji)上(shang)釋放電(dian)(dian)(dian)荷(he)并沉(chen)積在(zai)電(dian)(dian)(dian)極(ji)(ji)上(shang)，達(da)到收(shou)(shou)塵(chen)目(mu)的(de)。兩極(ji)(ji)系統均有振(zhen)打(da)裝(zhuang)(zhuang)置(zhi)(zhi)，當振(zhen)打(da)錘周期性的(de)敲打(da)兩極(ji)(ji)裝(zhuang)(zhuang)置(zhi)(zhi)時，粘附(fu)在(zai)其(qi)上(shang)的(de)粉塵(chen)被(bei)抖落(luo)，落(luo)入(ru)下(xia)部灰斗經(jing)排(pai)(pai)灰裝(zhuang)(zhuang)置(zhi)(zhi)排(pai)(pai)出機外。被(bei)凈(jing)(jing)化了(le)的(de)廢氣(qi)(qi)由出口經(jing)煙(yan)囪排(pai)(pai)入(ru)大氣(qi)(qi)中，此時完(wan)成了(le)煙(yan)氣(qi)(qi)凈(jing)(jing)化過程。

CDG型高壓(ya)靜電(dian)(dian)(dian)(dian)除塵器的除塵性(xing)能受粉塵性(xing)質、設備構(gou)造(zao)和煙氣流速等三個因素的影響。粉塵的比電(dian)(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)(dian)性(xing)的指標，它對除塵效率(lv)有直接的影響。比電(dian)(dian)(dian)(dian)阻過低，塵粒(li)難以保持在集塵電(dian)(dian)(dian)(dian)極上(shang)，致使其重(zhong)返氣流。比電(dian)(dian)(dian)(dian)阻過高，到(dao)達(da)集塵電(dian)(dian)(dian)(dian)極的塵粒(li)電(dian)(dian)(dian)(dian)荷不易放出，在塵層(ceng)之間形成電(dian)(dian)(dian)(dian)壓(ya)梯度會產生局部擊穿和放電(dian)(dian)(dian)(dian)現象。

CDG型高壓靜(jing)電除塵器(qi)的技(ji)術優越性：

CDG型高(gao)壓靜電除塵(chen)器的技術特點是：節能、穩定。

1、優化的結構設計

在(zai)除(chu)(chu)(chu)塵器結構設(she)計上，充分了(le)(le)考慮了(le)(le)粉塵慣性力(li)、離心(xin)力(li)、反靜電力(li)。二次揚塵以及供(gong)電電源的(de)波形性能、工作(zuo)特點等(deng)因(yin)素的(de)影響，采用優(you)化的(de)結構形式(shi)，大限(xian)度(du)的(de)提(ti)高遷移(yi)速度(du)，從而提(ti)高了(le)(le)除(chu)(chu)(chu)塵效(xiao)率。在(zai)處理同等(deng)塵源的(de)情況下(xia)，收(shou)塵面積可(ke)大幅度(du)下(xia)降，即除(chu)(chu)(chu)塵器的(de)尺(chi)寸和剛才消耗減少。這(zhe)種小空間(jian)、低成本設(she)計，為改造舊除(chu)(chu)(chu)塵設(she)備提(ti)供(gong)了(le)(le)非常(chang)有利的(de)條件。

2、   的(de)供電電源(yuan)

在(zai)除(chu)塵(chen)(chen)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)設(she)計上與常規不同(tong)。他(ta)采用的(de)是軟特性的(de)穩(wen)定(ding)直流電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)。穩(wen)定(ding)直流電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)比(bi)脈動直流電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)優(you)越(yue)。電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)工作(zuo)的(de)佳點是在(zai)火(huo)(huo)(huo)花(hua)(hua)始發以下(xia)臨界處(chu)。在(zai)設(she)計上，把電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)整(zheng)個(ge)過程夠控制在(zai)火(huo)(huo)(huo)花(hua)(hua)始發點以下(xia)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)暈放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)狀(zhuang)態。不讓其(qi)進入火(huo)(huo)(huo)花(hua)(hua)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)狀(zhuang)態。火(huo)(huo)(huo)花(hua)(hua)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)實質上是正、負離子在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場中發生碰中釋(shi)放(fang)(fang)能(neng)力的(de)一種現象，它對除(chu)塵(chen)(chen)毫無作(zuo)用。常規靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)在(zai)整(zheng)個(ge)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)過程中，包含了(le)火(huo)(huo)(huo)花(hua)(hua)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)和電(dian)(dian)(dian)(dian)(dian)(dian)暈放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)，并且(qie)絕(jue)大部分能(neng)量都在(zai)屬于火(huo)(huo)(huo)花(hua)(hua)電(dian)(dian)(dian)(dian)(dian)(dian)被浪費(fei)掉了(le)。而本技術(shu)在(zai)處(chu)理(li)同(tong)等塵(chen)(chen)源(yuan)的(de)情況下(xia)，電(dian)(dian)(dian)(dian)(dian)(dian)場耗能(neng)不足常規靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)之一。
