CJMA、CJMB型高壓靜(jing)電(dian)管式收(shou)塵器工作原理：

利用高壓電(dian)(dian)(dian)(dian)場使煙氣(qi)發(fa)生電(dian)(dian)(dian)(dian)離，氣(qi)流中的粉塵(chen)荷(he)電(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)場作用下與氣(qi)流分(fen)離。負極(ji)由(you)不(bu)同(tong)斷面形(xing)(xing)狀的金(jin)(jin)屬導線制成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不(bu)同(tong)幾何形(xing)(xing)狀的金(jin)(jin)屬板制成(cheng)，叫集(ji)塵(chen)電(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)器的性能受粉塵(chen)性質、設備(bei)構造(zao)(zao)和煙氣(qi)流速等三個(ge)因素(su)的影(ying)響。粉塵(chen)的比電(dian)(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)(dian)性的指標，它對(dui)除(chu)塵(chen)效率(lv)(lv)有直接的影(ying)響。比電(dian)(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)粒(li)難(nan)以保持在(zai)(zai)集(ji)塵(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使其(qi)重返(fan)氣(qi)流。比電(dian)(dian)(dian)(dian)阻(zu)過(guo)高，到達(da)集(ji)塵(chen)電(dian)(dian)(dian)(dian)極(ji)的塵(chen)粒(li)電(dian)(dian)(dian)(dian)荷(he)不(bu)易(yi)放(fang)出，在(zai)(zai)塵(chen)層之間形(xing)(xing)成(cheng)電(dian)(dian)(dian)(dian)壓梯(ti)度(du)會(hui)產生局部擊(ji)穿(chuan)和放(fang)電(dian)(dian)(dian)(dian)現象。這些情況都(dou)會(hui)造(zao)(zao)成(cheng)除(chu)塵(chen)效率(lv)(lv)下降。

1、優化的結構設計

在除(chu)(chu)塵器結(jie)構設(she)計上，充分了考慮了粉塵慣性(xing)力、離心力、反靜電力。二次揚塵以(yi)及供電電源(yuan)的波(bo)形性(xing)能、工作特點等(deng)因素的影響，采(cai)用優化的結(jie)構形式，   大限度的提(ti)(ti)高遷(qian)移速度，從而提(ti)(ti)高了除(chu)(chu)塵效率。在處理同(tong)等(deng)塵源(yuan)的情況下，收塵面積可大幅度下降，即除(chu)(chu)塵器的尺寸和剛才消耗減(jian)少(shao)。這種小空間、低(di)成本、   設(she)計，為(wei)改造舊除(chu)(chu)塵設(she)備提(ti)(ti)供了非常有利的條件。

2、   的供電(dian)電(dian)源

在(zai)除(chu)塵(chen)供電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)設計上與(yu)常(chang)(chang)規(gui)(gui)不(bu)(bu)同。他(ta)采用(yong)(yong)的(de)(de)是(shi)軟特性(xing)的(de)(de)穩定直流電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)。穩定直流電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)比脈動直流電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)優(you)越。電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)工作的(de)(de)   佳點是(shi)在(zai)火(huo)(huo)花始發以下臨界處(chu)。在(zai)設計上，把(ba)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)供電(dian)(dian)(dian)(dian)(dian)(dian)整個(ge)過程夠控(kong)制(zhi)在(zai)火(huo)(huo)花始發點以下的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)狀態。不(bu)(bu)讓其進入火(huo)(huo)花放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)狀態。火(huo)(huo)花放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)實質上是(shi)正、負(fu)離子在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場中(zhong)發生碰中(zhong)釋放(fang)能力的(de)(de)一種現象，它對除(chu)塵(chen)毫無作用(yong)(yong)。常(chang)(chang)規(gui)(gui)靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)在(zai)整個(ge)供電(dian)(dian)(dian)(dian)(dian)(dian)過程中(zhong)，包含了火(huo)(huo)花放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)和電(dian)(dian)(dian)(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)，并且(qie)絕大部(bu)分能量都在(zai)屬于火(huo)(huo)花電(dian)(dian)(dian)(dian)(dian)(dian)被浪費掉了。而(er)本技術(shu)在(zai)處(chu)理同等塵(chen)源(yuan)的(de)(de)情況(kuang)下，電(dian)(dian)(dian)(dian)(dian)(dian)場耗能不(bu)(bu)足常(chang)(chang)規(gui)(gui)靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)的(de)(de)之一。
