臥式靜電除塵器是眾多除塵器當中的一種，臥式靜電除塵器是以靜電凈化法來收捕廢氣中的粉塵的設備，其主要是讓含塵氣體進人氣刺叭時，含塵氣體受到氣流分布板以及折流板的調整后，使氣流能較均勻地進人電場。

臥式(shi)靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)器是以靜(jing)電(dian)(dian)(dian)(dian)凈化(hua)(hua)法來(lai)收捕廢氣(qi)(qi)(qi)中(zhong)的(de)粉(fen)塵(chen)，它的(de)凈化(hua)(hua)工作上(shang)(shang)要是依靠電(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)和(he)(he)沉(chen)淀兩(liang)個系統來(lai)完(wan)成的(de)，當含塵(chen)氣(qi)(qi)(qi)體(ti)(ti)進人(ren)氣(qi)(qi)(qi)刺叭(ba)時，含塵(chen)氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流分(fen)布板(ban)以及折流板(ban)的(de)調整(zheng)后，使(shi)氣(qi)(qi)(qi)流能(neng)較均勻地(di)進人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)橫斷面(mian)擴大的(de)作用下，氣(qi)(qi)(qi)流速(su)度迅速(su)降低，其中(zhong)有(you)些較重(zhong)的(de)塵(chen)粒便失去速(su)度而沉(chen)降下來(lai)。進人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)含塵(chen)氣(qi)(qi)(qi)體(ti)(ti)由(you)于(yu)電(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)通人(ren)高(gao)壓直流電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)暈(yun)(yun)現象，使(shi)氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)氣(qi)(qi)(qi)體(ti)(ti)中(zhong)存在(zai)大量(liang)的(de)電(dian)(dian)(dian)(dian)子和(he)(he)離子，這些電(dian)(dian)(dian)(dian)子和(he)(he)離子與進人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)粉(fen)塵(chen)結(jie)合起(qi)來(lai)，使(shi)塵(chen)粒帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)粒在(zai)電(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)作用下趨向本設(she)備陽(yang)極(ji)(正極(ji)、本設(she)備采用負(fu)(fu)高(gao)壓制)和(he)(he)陰極(ji)(負(fu)(fu)極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子分(fen)別沉(chen)積在(zai)相應的(de)電(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)，通過設(she)備陰陽(yang)極(ji)振打(da)系統的(de)振打(da)，使(shi)沉(chen)積在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)的(de)粉(fen)塵(chen)振落，進人(ren)集灰斗(dou) 通過排灰裝(zhuang)置放出，回收有(you)物料，被(bei))凈化(hua)(hua)的(de)氣(qi)(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)工作原(yuan)理是(shi)利(li)用高壓電(dian)(dian)(dian)場(chang)使(shi)煙(yan)氣(qi)(qi)發生電(dian)(dian)(dian)離，氣(qi)(qi)流中的(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)作用下與(yu)氣(qi)(qi)流分離。負極(ji)由(you)不同斷面形(xing)狀(zhuang)的(de)(de)金屬導線制成(cheng)，叫(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同幾(ji)何形(xing)狀(zhuang)的(de)(de)金屬板(ban)制成(cheng)，叫(jiao)集塵(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)性能(neng)受粉(fen)塵(chen)(chen)性質(zhi)、設備(bei)構造和煙(yan)氣(qi)(qi)流速等三(san)個(ge)因素的(de)(de)影(ying)響。粉(fen)塵(chen)(chen)的(de)(de)比電(dian)(dian)(dian)阻是(shi)評(ping)價導電(dian)(dian)(dian)性的(de)(de)指標，它對(dui)除塵(chen)(chen)效率(lv)有直接(jie)的(de)(de)影(ying)響。比電(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難以保持(chi)在集塵(chen)(chen)電(dian)(dian)(dian)極(ji)上(shang)，致使(shi)其重返氣(qi)(qi)流。比電(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷不易放出，在塵(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)壓梯(ti)度會產生局部擊(ji)穿和放電(dian)(dian)(dian)現(xian)象。這些情況都會造成(cheng)除塵(chen)(chen)效率(lv)下降。

電(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)基本原理是利用電(dian)(dian)(dian)力捕集煙氣中的(de)粉(fen)塵(chen)(chen)，主要(yao)包括以(yi)下四個(ge)相(xiang)互有關的(de)物理過程(cheng): (1) 氣體的(de)電(dian)(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)的(de)荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉(fen)塵(chen)(chen)向電(dian)(dian)(dian)極(ji)移動(dong)。(4) 荷電(dian)(dian)(dian)粉(fen)塵(chen)(chen)的(de)捕集。
