濕式(shi)靜電除(chu)霧器(qi)

設備介紹：

高濃度(du)的酸(suan)(suan)霧氣體、含塵(chen)含硫氣體，在經(jing)過中和吸收凈化(hua)之(zhi)后，會產生大量(liang)的煙霧，如三酸(suan)(suan)、鉻(ge)酸(suan)(suan)、氫氟酸(suan)(suan)、二氧化(hua)硫等。

如(ru)果風(feng)(feng)量(liang)和(he)風(feng)(feng)速較大時，情況會(hui)加(jia)劇，部分廢氣可能沒完全中(zhong)和(he)，而達不到排放(fang)標準。這時我們就(jiu)需要(yao)進行除霧處理。

濕式(shi)靜電(dian)除霧(wu)器(qi)也叫(jiao)濕式(shi)電(dian)除霧(wu)器(qi)，濕式(shi)電(dian)除塵器(qi)。廣泛應用(yong)于酸霧(wu)處理、脫硫除塵等工業(ye)生(sheng)產中(zhong)，已經有上百年的應用(yong)歷(li)史。

適用范圍：

用于酸(suan)霧(wu)中(zhong)和處理(li)之(zhi)后(hou)；濕(shi)法除塵(chen)脫硫裝置后(hou)的除煙霧(wu)。廣(guang)泛用于酸(suan)洗、電鍍、鋁材、冶金、磚廠、發電、鍋爐、化工、電子、機(ji)械制造等行業過程(cheng)中(zhong)排放的酸(suan)堿性(xing)、含塵(chen)含硫廢氣除霧(wu)處理(li)。

設備結(jie)構：

主體(ti)外殼采用(yong)不銹(xiu)鋼316L板材，內(nei)置陰極棒、陽(yang)極板束、絕緣(yuan)箱、清潔(jie)水(shui)系統(tong)；主體(ti)外殼下(xia)面(mian)是沉淀(dian)收(shou)集(ji)室：設(she)有觀察(cha)窗和排放口，可用(yong)水(shui)泥、塑料或(huo)玻璃(li)鋼作(zuo)成(cheng)的(de)廢水(shui)收(shou)集(ji)池。

設(she)備(bei)原理：

其原理(li)是向電場(chang)空間(jian)輸(shu)送直流負高壓，通過空間(jian)氣(qi)體電離，煙(yan)氣(qi)中粉(fen)塵顆粒(li)(li)和霧滴顆粒(li)(li)荷電后在電場(chang)力的(de)作用(yong)下，移(yi)動到電極板上，并使得(de)液(ye)滴越(yue)來越(yue)大，重(zhong)力作用(yong)下流到沉淀收集室中。

性能(neng)特點(dian):

1.除霧(wu)效率(lv)高95%以(yi)上，氣體(ti)懸浮顆(ke)粒及霧(wu)經(jing)在0.01--100um均可除去，對煙塵、煙霧(wu)適(shi)用范(fan)圍廣泛，工藝成熟(shu)、安(an)全可靠；

2.耐腐蝕、不磨損(sun)、使用(yong)壽命長(chang)，在維護好(hao)電極(ji)正常的情況下可(ke)長(chang)期使用(yong)；

3.阻力小、能(neng)耗省、噪音低，維(wei)護簡單、方便。

濕式(shi)(shi)靜電(dian)(dian)(dian)除(chu)霧器與干式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器工作(zuo)原理相(xiang)同(tong)，都是向(xiang)電(dian)(dian)(dian)場(chang)(chang)空間輸送直流(liu)負(fu)高(gao)(gao)壓，通過空間氣(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)離，煙(yan)(yan)(yan)氣(qi)(qi)(qi)(qi)中(zhong)(zhong)粉(fen)塵(chen)(chen)(chen)(chen)顆粒和(he)霧滴顆粒荷電(dian)(dian)(dian)后在(zai)電(dian)(dian)(dian)場(chang)(chang)力的(de)作(zuo)用(yong)下，移動(dong)到(dao)(dao)(dao)收(shou)(shou)(shou)塵(chen)(chen)(chen)(chen)極(ji)板（集電(dian)(dian)(dian)極(ji)），從(cong)而被收(shou)(shou)(shou)集在(zai)收(shou)(shou)(shou)塵(chen)(chen)(chen)(chen)極(ji)表面(mian)。干式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器利(li)用(yong)振(zhen)打清灰(hui)(hui)方式(shi)(shi)將(jiang)(jiang)收(shou)(shou)(shou)集到(dao)(dao)(dao)的(de)粉(fen)塵(chen)(chen)(chen)(chen)震落(luo)到(dao)(dao)(dao)灰(hui)(hui)斗中(zhong)(zhong)，而濕式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器則是通過收(shou)(shou)(shou)集煙(yan)(yan)(yan)氣(qi)(qi)(qi)(qi)中(zhong)(zhong)的(de)霧滴顆粒，在(zai)收(shou)(shou)(shou)塵(chen)(chen)(chen)(chen)極(ji)表面(mian)形成溢(yi)流(liu)而將(jiang)(jiang)粉(fen)塵(chen)(chen)(chen)(chen)沖(chong)洗到(dao)(dao)(dao)灰(hui)(hui)斗（水灰(hui)(hui)斗）中(zhong)(zhong)。濕式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器與干式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器最大的(de)不(bu)(bu)同(tong)，在(zai)于(yu)煙(yan)(yan)(yan)氣(qi)(qi)(qi)(qi)工質(zhi)的(de)差異，干式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器煙(yan)(yan)(yan)氣(qi)(qi)(qi)(qi)為干煙(yan)(yan)(yan)氣(qi)(qi)(qi)(qi)，煙(yan)(yan)(yan)氣(qi)(qi)(qi)(qi)溫(wen)度(du)較(jiao)高(gao)(gao)，煙(yan)(yan)(yan)氣(qi)(qi)(qi)(qi)中(zhong)(zhong)基本不(bu)(bu)含(han)霧滴。而濕式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器為濕飽和(he)煙(yan)(yan)(yan)氣(qi)(qi)(qi)(qi)，煙(yan)(yan)(yan)氣(qi)(qi)(qi)(qi)溫(wen)度(du)較(jiao)低，煙(yan)(yan)(yan)氣(qi)(qi)(qi)(qi)中(zhong)(zhong)含(han)有(you)大量的(de)霧滴。濕式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器通常設置在(zai)濕法脫硫裝置后，脫硫后飽和(he)煙(yan)(yan)(yan)氣(qi)(qi)(qi)(qi)中(zhong)(zhong)攜帶大量水滴，在(zai)通過高(gao)(gao)壓電(dian)(dian)(dian)場(chang)(chang)時被捕獲，能夠減小石膏(gao)雨形成的(de)幾率(lv)。同(tong)時對于(yu)收(shou)(shou)(shou)集微細顆粒物PM2.5、酸霧等有(you)較(jiao)好的(de)效果，煙(yan)(yan)(yan)塵(chen)(chen)(chen)(chen)排放濃度(du)可以達(da)到(dao)(dao)(dao)≤10毫(hao)克/立方米(mi)。
