烘干機(ji)高壓靜電是采用高壓靜電原理凈化含塵氣體的設(she)備，是專為水泥廠回(hui)轉式烘干機(ji)配套的除塵設(she)備。

烘干機高壓靜電(dian)除(chu)(chu)塵(chen)器是CDLG(H)型的代、第三代產品。在結構和(he)(he)性能上又有(you)很大(da)的改進和(he)(he)提高。回(hui)轉烘干機寬間(jian)距電(dian)除(chu)(chu)塵(chen)器技術(shu)性能。

烘干機高壓靜電除塵器(qi)工作原(yuan)理：

利用高(gao)壓電(dian)(dian)(dian)場使(shi)煙(yan)(yan)氣(qi)發生電(dian)(dian)(dian)離(li)，氣(qi)流(liu)中的(de)(de)(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作用下與氣(qi)流(liu)分(fen)離(li)。負極由不(bu)同(tong)(tong)斷面形狀(zhuang)的(de)(de)(de)金屬導(dao)(dao)線制成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由不(bu)同(tong)(tong)幾何形狀(zhuang)的(de)(de)(de)金屬板制成(cheng)，叫(jiao)集塵(chen)(chen)電(dian)(dian)(dian)極。靜電(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)性能受粉塵(chen)(chen)性質、設(she)備構造和煙(yan)(yan)氣(qi)流(liu)速(su)等三(san)個因素的(de)(de)(de)影響。粉塵(chen)(chen)的(de)(de)(de)比(bi)(bi)電(dian)(dian)(dian)阻是評價導(dao)(dao)電(dian)(dian)(dian)性的(de)(de)(de)指標，它(ta)對除塵(chen)(chen)效(xiao)率(lv)有直(zhi)接的(de)(de)(de)影響。比(bi)(bi)電(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)粒(li)難以保持在(zai)集塵(chen)(chen)電(dian)(dian)(dian)極上，致(zhi)使(shi)其重返氣(qi)流(liu)。比(bi)(bi)電(dian)(dian)(dian)阻過高(gao)，到(dao)達集塵(chen)(chen)電(dian)(dian)(dian)極的(de)(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)荷不(bu)易(yi)放(fang)出，在(zai)塵(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)壓梯度會產生局部擊穿和放(fang)電(dian)(dian)(dian)現象(xiang)。這些情況都會造成(cheng)除塵(chen)(chen)效(xiao)率(lv)下降。

1、優化的結構設計

在除(chu)塵(chen)器(qi)結構(gou)設(she)(she)計上，充分了(le)考(kao)慮(lv)了(le)粉塵(chen)慣性(xing)力(li)、離心(xin)力(li)、反靜電力(li)。二次揚塵(chen)以及供(gong)電電源的波形(xing)(xing)性(xing)能、工作(zuo)特點(dian)等因(yin)素的影響(xiang)，采用優化的結構(gou)形(xing)(xing)式(shi)，較(jiao)大限(xian)度(du)的提(ti)高(gao)遷移速度(du)，從而提(ti)高(gao)了(le)除(chu)塵(chen)效率。在處理同等塵(chen)源的情況下(xia)，收塵(chen)面積可大幅度(du)下(xia)降，即除(chu)塵(chen)器(qi)的尺寸(cun)和(he)剛才消耗減少。這種小空間(jian)、低(di)成本、設(she)(she)計，為(wei)改造舊除(chu)塵(chen)設(she)(she)備提(ti)供(gong)了(le)非常有利的條件。

2、的供電電源

在除(chu)塵(chen)供(gong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)源設計(ji)上(shang)(shang)與常(chang)規(gui)不同。他采用的(de)是(shi)軟特(te)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)壓比脈動直(zhi)流電(dian)(dian)(dian)(dian)(dian)壓。電(dian)(dian)(dian)(dian)(dian)源工作是(shi)在火(huo)(huo)(huo)花始(shi)發(fa)以下臨界處(chu)。在設計(ji)上(shang)(shang)，把(ba)電(dian)(dian)(dian)(dian)(dian)源供(gong)電(dian)(dian)(dian)(dian)(dian)整個(ge)過程夠控制在火(huo)(huo)(huo)花始(shi)發(fa)點以下的(de)電(dian)(dian)(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)(dian)(dian)狀(zhuang)態(tai)。不讓其進入(ru)火(huo)(huo)(huo)花放電(dian)(dian)(dian)(dian)(dian)狀(zhuang)態(tai)。火(huo)(huo)(huo)花放電(dian)(dian)(dian)(dian)(dian)實質上(shang)(shang)是(shi)正、負離(li)子在電(dian)(dian)(dian)(dian)(dian)場中發(fa)生碰(peng)中釋放能(neng)力(li)的(de)一種現(xian)象，它對除(chu)塵(chen)毫(hao)無作用。常(chang)規(gui)靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器在整個(ge)供(gong)電(dian)(dian)(dian)(dian)(dian)過程中，包含(han)了火(huo)(huo)(huo)花放電(dian)(dian)(dian)(dian)(dian)和電(dian)(dian)(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)(dian)(dian)，并(bing)且絕大部分能(neng)量都在屬于火(huo)(huo)(huo)花電(dian)(dian)(dian)(dian)(dian)被浪費(fei)掉(diao)了。而本技術(shu)在處(chu)理同等塵(chen)源的(de)情況下，電(dian)(dian)(dian)(dian)(dian)場耗能(neng)不足常(chang)規(gui)靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器的(de)之一。
