焦化廠地面(mian)站(zhan)除塵器優點：

1、裝煤除(chu)塵采(cai)用非燃燒(shao)方式兌入(ru)大(da)量的(de)空氣，使(shi)煙(yan)(yan)塵中(zhong)的(de)可燃成分含量遠低于(yu)爆炸(zha)下限，了煙(yan)(yan)塵進入(ru)除(chu)塵大(da)系(xi)統(tong)中(zhong)是(shi)的(de)；

2、焦側除塵(chen)系統收(shou)集(ji)的是(shi)干燥(zao)的焦粉(fen)和氣體能(neng)的吸收(shou)裝煤煙塵(chen)中的成分，焦油和水分，不需(xu)考(kao)慮除塵(chen)設(she)備的保溫，加熱，防結露等措施；

3、焦化廠地面站除塵(chen)器采用低壓管噴提高了除塵(chen)器的清灰能力，防止粉塵(chen)粘結濾(lv)料，而增大系統阻(zu)力；

4、本系統設計充分發揮地(di)面除(chu)塵(chen)設備的凈(jing)化處理能力(li)，通過(guo)風機和管路(lu)系統的設計和控制(zhi)使裝煤除(chu)塵(chen)與焦側除(chu)塵(chen)合(he)為一(yi)個系統，可節省改(gai)造(zao)投資。

由于焦(jiao)爐的(de)工藝特點(dian)即煉(lian)焦(jiao)用煤(mei)揮發份，裝(zhuang)煤(mei)時會產生(sheng)大量(liang)(liang)的(de)煙(yan)塵(chen)，針對(dui)裝(zhuang)煤(mei)煙(yan)塵(chen)煙(yan)氣含濕(shi)量(liang)(liang)大，露點(dian)溫度(du)比較高(gao)，且煙(yan)塵(chen)呈絮狀(zhuang)，漂浮性等特點(dian)，焦(jiao)化廠治理(li)大氣環境污(wu)染采(cai)用阻火布(bu)袋除(chu)塵(chen)地面站系統，除(chu)塵(chen)效果(guo)理(li)想。
