濕(shi)(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)器(qi)(qi)是設計(ji)在布袋(dai)除(chu)(chu)(chu)塵(chen)器(qi)(qi)脫(tuo)硫(liu)脫(tuo)硝(xiao)之后的(de)一道工序，濕(shi)(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)器(qi)(qi)起著超低(di)排放的(de)作用(yong)，另(ling)外濕(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)器(qi)(qi)也可以和脫(tuo)硫(liu)脫(tuo)硝(xiao)一體(ti)化設計(ji)，把濕(shi)(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)器(qi)(qi)設計(ji)在脫(tuo)硫(liu)脫(tuo)硝(xiao)塔體(ti)的(de)最高處，利用(yong)旋流作用(yong)緩沖高壓靜(jing)電(dian)(dian)(dian)(dian)振打把粉塵(chen)降(jiang)落在電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)器(qi)(qi)灰倉內(nei)，濕(shi)(shi)式(shi)(shi)靜(jing)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)器(qi)(qi)配件玻(bo)璃(li)鋼陽管材(cai)質(zhi)主(zhu)要為(wei)導電(dian)(dian)(dian)(dian)玻(bo)璃(li)鋼，常(chang)用(yong)于濕(shi)(shi)式(shi)(shi)靜(jing)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)器(qi)(qi)的(de)導電(dian)(dian)(dian)(dian)玻(bo)璃(li)鋼陽管多為(wei)正(zheng)六邊形(xing)規格，管內(nei)切圓直徑250mm~400mm，管長可(ke)達6米，管壁厚約3mm。陽管模塊由若干根正六邊(bian)形(xing)管組(zu)(zu)合在一起組(zu)(zu)成沉淀。陽模塊管數可根據客戶要求(qiu)定(ding)制，成套模塊組(zu)(zu)裝由端部(bu)法蘭制作，外部(bu)加固(gu)等工序組(zu)(zu)成。 濕式靜(jing)電(dian)除塵(chen)器(qi)導(dao)電(dian)玻璃(li)鋼陽管特點：耐腐蝕(shi)性強，能耐各(ge)種稀酸(suan)、堿(jian)、鹽等高腐蝕(shi)介(jie)質的(de)腐蝕(shi)。導(dao)電(dian)性能優(you)良、除塵(chen)除霧效率高重量輕、強度(du)高，外(wai)形尺寸確定，節省支撐平臺費用，延(yan)長了設(she)備的(de)使用壽(shou)命。結構(gou)緊湊，蜂窩型結構(gou)使每個管的(de)內外(wai)表面都成為沉(chen)淀表面。阻燃性好(hao)，材料(liao)的氧指數可達30使用壽(shou)命(ming)長，一(yi)般(ban)可達20年以上。濕(shi)式(shi)靜(jing)電除(chu)塵(chen)器導電玻(bo)璃(li)鋼陽(yang)管應(ying)用(yong)范圍：導電玻(bo)璃(li)鋼陽(yang)管主要應(ying)用(yong)于(yu)濕(shi)式(shi)靜(jing)電除(chu)塵(chen)（霧(wu)）器、電捕焦油器等除(chu)塵(chen)除(chu)霧(wu)設(she)備的陽(yang)模塊(kuai)。

因此(ci)，濕式(shi)電除(chu)塵(chen)(chen)器(qi) 結構，濕式(shi)電除(chu)塵(chen)(chen)器(qi)適合(he)與(yu)濕法(fa)煙氣脫硫系統結合(he)，用(yong)于捕集脫硫凈化后的(de)濕煙氣中(zhong)的(de)微細(xi)粉(fen)塵(chen)(chen)、酸霧、液滴及金屬顆粒如gong 等。

濕式電除(chu)塵器(qi)的不足(zu)之處：

（1）由于濕(shi)式電除塵器內有(you)腐(fu)蝕(shi)性(xing)液體(ti)介(jie)質(zhi)存在(zai)(zai)且溫度(du)在(zai)(zai)露在(zai)(zai)外面以下，因(yin)此WESP各主要(yao)部件(jian)選材濕(shi)式電除塵器慮介(jie)質(zhi)的腐(fu)蝕(shi)性(xing)，均需有(you)一(yi)定的耐腐(fu)蝕(shi)性(xing)能或采取相應的防(fang)腐(fu)措施，尤(you)其(qi)是陰、陽電極；

（2）當采用金(jin)屬極板濕式電除塵器時需要設置廢水循環(huan)利用處理設備(bei)。

濕式電除塵器配件主要有玻璃鋼陽級管高壓振打和2205陰極線配置組合而成(cheng)。玻璃鋼陽(yang)管(guan)主要應(ying)用(yong)(yong)(yong)于濕式(shi)靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)（霧）器、電(dian)(dian)(dian)捕焦油器等除(chu)塵(chen)(chen)(chen)除(chu)霧設備的(de)(de)陽(yang)模塊。濕式(shi)靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)收(shou)塵(chen)(chen)(chen)原理(li)與干式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器相同，均經(jing)歷荷電(dian)(dian)(dian)、收(shou)集和(he)(he)(he)清(qing)灰(hui)三(san)個(ge)階段。金屬放電(dian)(dian)(dian)線在(zai)直(zhi)流(liu)(liu)高電(dian)(dian)(dian)壓的(de)(de)作(zuo)用(yong)(yong)(yong)下(xia)，將其周圍氣(qi)體電(dian)(dian)(dian)離(li)，使粉塵(chen)(chen)(chen)或霧滴(di)粒(li)子表面荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)粒(li)子在(zai)電(dian)(dian)(dian)場力的(de)(de)作(zuo)用(yong)(yong)(yong)下(xia)向收(shou)塵(chen)(chen)(chen)運(yun)動，并(bing)沉積在(zai)收(shou)塵(chen)(chen)(chen)上，清(qing)灰(hui)方(fang)式(shi)多(duo)采用(yong)(yong)(yong)噴淋水流(liu)(liu)從集塵(chen)(chen)(chen)板(ban)頂端流(liu)(liu)下(xia)，在(zai)集塵(chen)(chen)(chen)板(ban)上形成(cheng)一層(ceng)均勻穩定(ding)的(de)(de)水膜，將板(ban)上的(de)(de)顆(ke)帶(dai)走，也有依(yi)據收(shou)集霧滴(di)自流(liu)(liu)的(de)(de)清(qing)灰(hui)方(fang)式(shi)。濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器（WESP)作(zuo)為(wei)大氣(qi)多(duo)污染物控制(zhi)系統的(de)(de)終(zhong)端精處(chu)理(li)裝備,具(ju)有捕集煙氣(qi)中超細顆(ke)粒(li)物和(he)(he)(he)霧滴(di)的(de)(de)功(gong)能,因此在(zai)化工(gong)和(he)(he)(he)電(dian)(dian)(dian)力領域(yu)得到了較(jiao)多(duo)應(ying)用(yong)(yong)(yong)。介紹了濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)工(gong)作(zuo)原理(li)、結構特點(dian)、材料(liao)選取和(he)(he)(he)布置形式(shi),以及濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器在(zai)燃煤電(dian)(dian)(dian)廠的(de)(de)應(ying)用(yong)(yong)(yong)情況和(he)(he)(he)今后(hou)的(de)(de)研(yan)究發展方(fang)向。
