西寧靜電除塵器公司

濕電除塵器是一種用來處理含微量粉塵和微顆粒的新除塵設備，主要用來除去含濕氣(qi)體中的塵(chen)、酸霧、水滴、氣(qi)溶膠、臭味(wei)、PM2.5等有害物質，是治理大氣(qi)粉塵(chen)污染的理想設(she)備。

濕電除塵器特點

WESP具有除塵(chen)效率高、壓力(li)損失小、操作簡單、能耗(hao)小、無(wu)運動(dong)部件、無(wu)二(er)次揚塵(chen)、維護費用(yong)低、生(sheng)產停工期(qi)短、可工作于煙氣露點溫度以下、由于結(jie)構緊湊而可與其它煙氣治理設備相互結(jie)合、設計形

濕電除塵器結構及分類

靜電除塵器公司主要(yao)有兩種(zhong)(zhong)(zhong)結(jie)構形(xing)式，一種(zhong)(zhong)(zhong)是使用耐(nai)腐蝕(shi)導電(dian)(dian)材(cai)料(liao)（可以為導電(dian)(dian)性(xing)能(neng)的的非金屬(shu)材(cai)料(liao)或具(ju)有耐(nai)腐蝕(shi)特性(xing)的金屬(shu)材(cai)料(liao)）做集(ji)塵極，另一種(zhong)(zhong)(zhong)是用通過噴水(shui)或溢流水(shui)形(xing)成導電(dian)(dian)水(shui)膜，利用不導電(dian)(dian)的非金屬(shu)材(cai)料(liao)做集(ji)塵極。

沉集在極板上的粉塵可以通過水將其沖洗下來。濕式清灰可以避免已捕集粉塵的再飛揚，達到很高的除塵效率。因無振打裝置，運行也較可靠。采用噴水或溢流水等方式使集塵極表面形成導電膜的裝置存在著腐蝕、污泥和污水的處理問題，僅在氣體含塵濃度較低、要求除塵效率較高時才采用；使用耐腐蝕導電材料做集塵極的濕式電除塵器不(bu)需要長期(qi)噴水或溢(yi)流水，只(zhi)根據系統(tong)運行狀況定期(qi)進行沖(chong)洗，僅消(xiao)耗(hao)極少量的(de)水，該部分(fen)水可回收循環利用，收塵(chen)系統(tong)基(ji)本無二次污(wu)染。

濕式電除塵器還可根據廢氣流向分為橫流式（臥式）和豎流式（立式），橫流式多為板式結構，氣體流向為水平方向進出，結構類似干式電除塵器；豎流(liu)(liu)式多為(wei)管式結構，氣體流(liu)(liu)向為(wei)垂(chui)直(zhi)方向進出(chu)。一般來講，同等通氣截(jie)面積情況(kuang)下(xia)豎流(liu)(liu)式濕式電除(chu)塵器效率為(wei)橫(heng)流(liu)(liu)式的(de)2倍。

多樣化等優點。

濕式電除塵器采用液體沖刷集塵極表面來進行清灰，可有效收集微細顆粒物（PM2.5粉塵、SO3酸霧、氣溶膠）、重金屬（Hg、As、Se、Pb、Cr）、有機污染物（多環芳烴、二噁英）等。使用濕式電除塵器后含濕煙氣中的煙塵排放可達10mg/m3甚至5mg/m3以下，收塵性能與粉塵特性無關，適用于含濕煙氣的處理，尤其適用在電廠、鋼廠濕法脫硫之后含塵(chen)(chen)煙氣的處理上，但設備(bei)投資(zi)費(fei)用較高，且需與其它(ta)除塵(chen)(chen)設備(bei)配套(tao)使用，其投資(zi)技(ji)術經濟性和運行成本要從整體(ti)進行評價。
