脫硫除塵器(qi)在(zai)哪些情況下會(hui)發生結(jie)露現象?除塵布(bu)袋收集的粉塵經星形(xing)卸(xie)灰閥(fa)、螺旋運(yun)送儀(yi)、打包(bao)，由轎(jiao)車外運(yun)。殼(ke)體旋風除塵器(qi)流型計劃，能起有些旋風作用(yong)，減(jian)輕濾(lv)(lv)袋負荷。填充式過濾(lv)(lv)床過濾(lv)(lv)填充式過濾(lv)(lv)床便是(shi)在(zai)網孔滾筒、平板等部件上包(bao)覆泡(pao)沫塑料(liao)、非織造布(bu)、長毛絨(rong)等多(duo)孔性過濾(lv)(lv)材料(liao)。 

    硫在(zai)(zai)較低(di)溫(wen)度(du)下開(kai)始(shi)從煤中(zhong)(zhong)(zhong)(zhong)析出(chu)(chu)分(fen)(fen)(fen)解，在(zai)(zai)氧(yang)化(hua)(hua)性(xing)氣(qi)(qi)氛下，最終全部形成(cheng)SO2。在(zai)(zai)還原(yuan)性(xing)氣(qi)(qi)氛下，硫會轉化(hua)(hua)為H2S和(he) COS， 如(ru)果(guo)再遇(yu)到O2就又形成(cheng)SO2，如(ru)，2H2S + O2 --- SO2 +2H2O。空氣(qi)(qi)中(zhong)(zhong)(zhong)(zhong)含有量的(de)(de)(de)水(shui)蒸氣(qi)(qi)，當(dang)它(ta)與(yu)一冷(leng)面相(xiang)(xiang)接觸(chu)時(shi)，如(ru)果(guo)冷(leng)面的(de)(de)(de)溫(wen)度(du)與(yu)空氣(qi)(qi)中(zhong)(zhong)(zhong)(zhong)水(shui)蒸氣(qi)(qi)的(de)(de)(de)分(fen)(fen)(fen)壓力相(xiang)(xiang)對應的(de)(de)(de)飽和(he)溫(wen)度(du)相(xiang)(xiang)等(deng)或(huo)時(shi)，水(shui)蒸氣(qi)(qi)就會部分(fen)(fen)(fen)地(di)凝結在(zai)(zai)冷(leng)面上，這就是(shi)所謂(wei)“結露”現象。開(kai)始(shi)結露的(de)(de)(de)溫(wen)度(du)稱為露點。通常，煙(yan)氣(qi)(qi)中(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)水(shui)蒸氣(qi)(qi)含量高于大(da)(da)氣(qi)(qi)，露點也較高，大(da)(da)約在(zai)(zai)50℃以下。若能(neng)出(chu)(chu)適合該(gai)(gai)系統的(de)(de)(de)新型、低(di)阻旋(xuan)風(feng)除塵器，能(neng)大(da)(da)幅度(du)降低(di)該(gai)(gai)單元的(de)(de)(de)操作費用，創造巨(ju)大(da)(da)的(de)(de)(de)經濟效益。吸收(shou)(shou)法凈化(hua)(hua)氣(qi)(qi)態污(wu)染(ran)物是(shi)利用氣(qi)(qi)體混合物中(zhong)(zhong)(zhong)(zhong)各種(zhong)成(cheng)分(fen)(fen)(fen)在(zai)(zai)吸收(shou)(shou)劑中(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)溶解度(du)不同，或(huo)者與(yu)吸收(shou)(shou)劑中(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)組分(fen)(fen)(fen)發(fa)生選擇性(xing)化(hua)(hua)學反應，從而將組分(fen)(fen)(fen)從氣(qi)(qi)流中(zhong)(zhong)(zhong)(zhong)分(fen)(fen)(fen)離(li)出(chu)(chu)來(lai)的(de)(de)(de)操作過程。吸收(shou)(shou)法凈化(hua)(hua)氣(qi)(qi)態污(wu)染(ran)物是(shi)利用氣(qi)(qi)體混合物中(zhong)(zhong)(zhong)(zhong)各種(zhong)成(cheng)分(fen)(fen)(fen)在(zai)(zai)吸收(shou)(shou)劑中(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)溶解度(du)不同，或(huo)者與(yu)吸收(shou)(shou)劑中(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)組分(fen)(fen)(fen)發(fa)生選擇性(xing)化(hua)(hua)學反應，從而將組分(fen)(fen)(fen)從氣(qi)(qi)流中(zhong)(zhong)(zhong)(zhong)分(fen)(fen)(fen)離(li)出(chu)(chu)來(lai)的(de)(de)(de)操作過程。
