除(chu)(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)(de)工作好壞，不僅(jin)直接(jie)影響到除(chu)(chu)塵(chen)(chen)(chen)(chen)系(xi)統的(de)(de)(de)可(ke)靠(kao)運(yun)行(xing)(xing)，還關系(xi)到生(sheng)產(chan)系(xi)統的(de)(de)(de)正常運(yun)行(xing)(xing)、車間(jian)廠區和(he)(he)周邊(bian)居(ju)民的(de)(de)(de)環境衛生(sheng)、風機葉片的(de)(de)(de)磨(mo)損和(he)(he)壽命，同時還涉及有經濟價值物(wu)料的(de)(de)(de)回收利用(yong)問題。因(yin)此，必須(xu)正確地(di)設計、選擇與使用(yong)除(chu)(chu)塵(chen)(chen)(chen)(chen)器。選擇除(chu)(chu)塵(chen)(chen)(chen)(chen)器時必須(xu)全面考慮一(yi)次投(tou)資(zi)和(he)(he)運(yun)行(xing)(xing)費(fei)用(yong)，如(ru)除(chu)(chu)塵(chen)(chen)(chen)(chen)效(xiao)率、壓力(li)損失、可(ke)靠(kao)性(xing)(xing)、一(yi)次投(tou)資(zi)、占地(di)面積、維修管理等因(yin)素，根據煙塵(chen)(chen)(chen)(chen)的(de)(de)(de)理化(hua)性(xing)(xing)質(zhi)、特(te)點(dian)和(he)(he)生(sheng)產(chan)工藝的(de)(de)(de)要求，針對(dui)性(xing)(xing)地(di)選擇除(chu)(chu)塵(chen)(chen)(chen)(chen)器。

1.根據除(chu)塵效率的要求

所選除(chu)塵器必須滿足排放標準(zhun)的要求。

不同(tong)的除(chu)(chu)塵(chen)(chen)器(qi)(qi)具有(you)不同(tong)的除(chu)(chu)塵(chen)(chen)效率。對于運行狀(zhuang)況不穩定或波動較(jiao)大(da)的除(chu)(chu)塵(chen)(chen)系(xi)統，要注(zhu)意煙氣處理(li)量變化對除(chu)(chu)塵(chen)(chen)效率的影響(xiang)。正(zheng)常運行時(shi)，除(chu)(chu)塵(chen)(chen)器(qi)(qi)的效率高低排序是(shi)：袋式除(chu)(chu)塵(chen)(chen)器(qi)(qi)、電除(chu)(chu)塵(chen)(chen)器(qi)(qi)及文丘(qiu)里除(chu)(chu)塵(chen)(chen)器(qi)(qi)、水膜旋風除(chu)(chu)塵(chen)(chen)器(qi)(qi)、旋風除(chu)(chu)塵(chen)(chen)器(qi)(qi)、慣性除(chu)(chu)塵(chen)(chen)器(qi)(qi)、重力除(chu)(chu)塵(chen)(chen)器(qi)(qi)

2.根據(ju)氣體性質

3.根(gen)據粉塵性質

粉(fen)塵(chen)(chen)(chen)(chen)(chen)性(xing)(xing)質包(bao)括比(bi)電(dian)(dian)阻、粒(li)度(du)、真密度(du)、瓢(piao)性(xing)(xing)、憎水性(xing)(xing)和(he)水硬性(xing)(xing)、可(ke)燃、爆(bao)炸等。比(bi)電(dian)(dian)阻過(guo)大(da)或(huo)過(guo)小(xiao)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)不(bu)宜采(cai)用(yong)電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)，袋式(shi)(shi)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)不(bu)受粉(fen)塵(chen)(chen)(chen)(chen)(chen)比(bi)電(dian)(dian)阻的(de)(de)(de)影響；粉(fen)塵(chen)(chen)(chen)(chen)(chen)的(de)(de)(de)濃度(du)和(he)粒(li)度(du)對電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)效率的(de)(de)(de)影響較(jiao)為顯(xian)(xian)著(zhu)，但對袋式(shi)(shi)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)的(de)(de)(de)影響不(bu)顯(xian)(xian)著(zhu)；當氣體(ti)的(de)(de)(de)含塵(chen)(chen)(chen)(chen)(chen)濃度(du)較(jiao)高時，電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)前(qian)宜設置(zhi)預除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)裝置(zhi)；袋式(shi)(shi)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)的(de)(de)(de)型式(shi)(shi)、清灰方(fang)式(shi)(shi)和(he)過(guo)濾風速取決于粉(fen)塵(chen)(chen)(chen)(chen)(chen)的(de)(de)(de)性(xing)(xing)質（粒(li)徑、瓢(piao)性(xing)(xing)）；濕式(shi)(shi)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)不(bu)適合于凈化(hua)憎水性(xing)(xing)和(he)水硬性(xing)(xing)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)：粉(fen)塵(chen)(chen)(chen)(chen)(chen)的(de)(de)(de)真密度(du)對重力除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)、慣性(xing)(xing)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)和(he)旋(xuan)風除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)的(de)(de)(de)影響顯(xian)(xian)著(zhu)；對于新(xin)附性(xing)(xing)大(da)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)，易(yi)導(dao)致(zhi)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)工(gong)作面貓結或(huo)堵(du)塞，因此(ci)，不(bu)宜采(cai)用(yong)干法除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)；粉(fen)塵(chen)(chen)(chen)(chen)(chen)凈化(hua)遇水后，能(neng)產生可(ke)燃或(huo)有爆(bao)炸危險的(de)(de)(de)混合物時，不(bu)得采(cai)用(yong)濕式(shi)(shi)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)。

4.根據壓力損失與能耗

袋式除塵器(qi)的阻力比電除塵器(qi)的阻力大，但從除塵器(qi)整體能(neng)(neng)耗來對比，兩者能(neng)(neng)耗相差不大。

5.根據設備投資和運行費用

6.節水與防凍的(de)要求

水(shui)資源缺乏的地區不適(shi)合采用濕式(shi)除塵器；北方地區存在冬季(ji)凍結的問題，盡可(ke)能(neng)不使用濕式(shi)除塵器。

7.粉塵和氣體(ti)回收利用的要求

粉(fen)塵具有(you)回收(shou)價值時，宜(yi)采用(yong)(yong)(yong)干法除(chu)(chu)塵；當粉(fen)塵具有(you)很(hen)高的回收(shou)價值時，宜(yi)采用(yong)(yong)(yong)袋(dai)式除(chu)(chu)塵器；當凈化后(hou)的氣體(ti)需要回收(shou)利(li)用(yong)(yong)(yong)或凈化后(hou)的空(kong)氣需要再循環利(li)用(yong)(yong)(yong)時，宜(yi)采用(yong)(yong)(yong)高效袋(dai)式除(chu)(chu)塵器。
