1.煙(yan)(yan)塵(chen)(chen)(chen)(chen)的(de)(de)(de)污染：煙(yan)(yan)塵(chen)(chen)(chen)(chen)的(de)(de)(de)污染是(shi)(shi)除塵(chen)(chen)(chen)(chen)作用(yong)欠(qian)(qian)好(hao)(hao)引(yin)起的(de)(de)(de)。開端以(yi)為(wei)是(shi)(shi)除塵(chen)(chen)(chen)(chen)器損壞(huai)，如隔(ge)板腐蝕穿孔構成煙(yan)(yan)氣(qi)(qi)(qi)(qi)(qi)(qi)短(duan)路所構成的(de)(de)(de)，經(jing)檢查(cha)除塵(chen)(chen)(chen)(chen)器完好(hao)(hao)。因此以(yi)為(wei)，除塵(chen)(chen)(chen)(chen)作用(yong)欠(qian)(qian)好(hao)(hao)只能(neng)是(shi)(shi)除塵(chen)(chen)(chen)(chen)功(gong)率(lv)不高引(yin)起。濕法收(shou)(shou)塵(chen)(chen)(chen)(chen)，是(shi)(shi)以(yi)水(shui)與煙(yan)(yan)塵(chen)(chen)(chen)(chen)直接接觸(chu)(chu)，運用(yong)液滴或(huo)液膜(mo)(mo)粘附煙(yan)(yan)塵(chen)(chen)(chen)(chen)而凈化煙(yan)(yan)氣(qi)(qi)(qi)(qi)(qi)(qi)，液滴越(yue)小，液膜(mo)(mo)面(mian)(mian)越(yue)大(da)(da)，收(shou)(shou)塵(chen)(chen)(chen)(chen)作用(yong)越(yue)好(hao)(hao)。為(wei)增大(da)(da)水(shui)與煙(yan)(yan)塵(chen)(chen)(chen)(chen)的(de)(de)(de)接觸(chu)(chu)面(mian)(mian)，規范的(de)(de)(de)濕法收(shou)(shou)塵(chen)(chen)(chen)(chen)器選用(yong)自(zi)激(ji)振動、文丘里管(guan)、篩板等方(fang)法，以(yi)進步收(shou)(shou)塵(chen)(chen)(chen)(chen)作用(yong)。該廠水(shui)浴式除塵(chen)(chen)(chen)(chen)器，結構相當(dang)簡略(lve)，矩形(xing)水(shui)箱中(zhong)(zhong)間只需一(yi)個隔(ge)板，沒(mei)有采取擴大(da)(da)煙(yan)(yan)氣(qi)(qi)(qi)(qi)(qi)(qi)與水(shui)接觸(chu)(chu)面(mian)(mian)的(de)(de)(de)有用(yong)方(fang)法，也沒(mei)有水(shui)氣(qi)(qi)(qi)(qi)(qi)(qi)分別設(she)備。煙(yan)(yan)氣(qi)(qi)(qi)(qi)(qi)(qi)經(jing)過隔(ge)板的(de)(de)(de)一(yi)側進入水(shui)中(zhong)(zhong)，由另一(yi)側進入煙(yan)(yan)道(dao)，煙(yan)(yan)氣(qi)(qi)(qi)(qi)(qi)(qi)和水(shui)的(de)(de)(de)接觸(chu)(chu)時間很短(duan)，導致煙(yan)(yan)氣(qi)(qi)(qi)(qi)(qi)(qi)和水(shui)混合欠(qian)(qian)好(hao)(hao)。煙(yan)(yan)氣(qi)(qi)(qi)(qi)(qi)(qi)在(zai)水(shui)中(zhong)(zhong)構成很大(da)(da)氣(qi)(qi)(qi)(qi)(qi)(qi)泡，氣(qi)(qi)(qi)(qi)(qi)(qi)泡中(zhong)(zhong)的(de)(de)(de)煙(yan)(yan)氣(qi)(qi)(qi)(qi)(qi)(qi)沒(mei)有接觸(chu)(chu)到(dao)水(shui)，收(shou)(shou)塵(chen)(chen)(chen)(chen)功(gong)率(lv)低。

　　經檢(jian)測，水位正常時(shi)，鍋爐出(chu)口煙(yan)(yan)氣(qi)中(zhong)煙(yan)(yan)塵(chen)(chen)(chen)濃度為2050mg/m3，除塵(chen)(chen)(chen)器(qi)后的煙(yan)(yan)塵(chen)(chen)(chen)濃度為350mg/m3，收塵(chen)(chen)(chen)后排出(chu)的煙(yan)(yan)塵(chen)(chen)(chen)顆粒較(jiao)大(da)。因(yin)煙(yan)(yan)氣(qi)管(guan)道很短，管(guan)道間聯接法(fa)蘭均(jun)用白厚漆加麻(ma)繩密封，打掃漏風要素影響，除塵(chen)(chen)(chen)功率只能達(da)到83%。

　　引風機是引起振動和噪聲的首要要素，引風機的動平衡欠好、工作過程中風葉損壞，均會構成振動。現場調查，引風機與除塵器均振動顯著，除塵器及聯接管道振幅較大。將風機與除塵器的聯接管道斷開后再開引風機，振動減小。風機葉片，只需細微損害，可開端以為振動是由除塵器發生的。

　　2.噪聲和振動(dong)：該除塵器(qi)煙氣經過的橫截(jie)面0.64m2，速度約3.5m/s，并(bing)(bing)以這種(zhong)速度進入(ru)水(shui)中(zhong)(zhong)，引(yin)風(feng)機開機時(shi)，除塵器(qi)中(zhong)(zhong)的水(shui)劇烈沸騰，并(bing)(bing)與(yu)引(yin)風(feng)機相互作用，振動(dong)由此發生(sheng)。

　　除了振(zhen)動，引風(feng)機(ji)工(gong)作(zuo)時(shi)的(de)噪聲很大。原體(ti)系(xi)選用的(de)引風(feng)機(ji)轉(zhuan)速高達(da)3250轉(zhuan)/min。這對進(jin)步風(feng)壓有利，但(dan)轉(zhuan)速越高，噪聲越大。當轉(zhuan)速低(di)于2500轉(zhuan)／min時(shi)，噪聲大大降低(di)。
