除塵(chen)(chen)(chen)器的工作(zuo)好壞，不僅直接(jie)影響到除塵(chen)(chen)(chen)系統的可(ke)(ke)靠(kao)(kao)運(yun)行，還關(guan)系到生(sheng)產系統的正常(chang)運(yun)行、車間(jian)廠區和(he)周邊居民(min)的環境衛生(sheng)、風機(ji)葉(xie)片的磨損和(he)壽命(ming)，同時(shi)還涉及有經(jing)濟價值物料的回收(shou)利(li)用(yong)問題。因此，必須正確地(di)(di)設計、選擇與使用(yong)除塵(chen)(chen)(chen)器。選擇除塵(chen)(chen)(chen)器時(shi)必須全面考慮一次投(tou)(tou)資和(he)運(yun)行費用(yong)，如除塵(chen)(chen)(chen)效率、壓力損失、可(ke)(ke)靠(kao)(kao)性、一次投(tou)(tou)資、占地(di)(di)面積(ji)、維修管理等因素，根據煙塵(chen)(chen)(chen)的理化(hua)性質、特點和(he)生(sheng)產工藝的要求，針對性地(di)(di)選擇除塵(chen)(chen)(chen)器。

1.根據除(chu)塵效率的要求

所選除塵器必(bi)須滿足(zu)排放標(biao)準的要求。

不(bu)(bu)同的(de)(de)除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)(qi)具有(you)不(bu)(bu)同的(de)(de)除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)效率(lv)。對于運行狀況不(bu)(bu)穩定或(huo)波動較(jiao)大(da)的(de)(de)除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)系統(tong)，要注意(yi)煙氣(qi)處理(li)量變化對除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)效率(lv)的(de)(de)影(ying)響。正常運行時，除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)(qi)的(de)(de)效率(lv)高低排(pai)序是：袋式除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)(qi)、電除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)(qi)及文(wen)丘里除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)(qi)、水(shui)膜旋風(feng)除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)(qi)、旋風(feng)除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)(qi)、慣性除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)(qi)、重力除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)(qi)

2.根據(ju)氣體性質

3.根據粉塵性質

粉(fen)(fen)塵(chen)(chen)(chen)(chen)性(xing)(xing)(xing)(xing)質包(bao)括比電(dian)(dian)(dian)阻(zu)(zu)、粒(li)度(du)、真(zhen)密度(du)、瓢(piao)性(xing)(xing)(xing)(xing)、憎(zeng)水性(xing)(xing)(xing)(xing)和(he)水硬性(xing)(xing)(xing)(xing)、可燃、爆炸等。比電(dian)(dian)(dian)阻(zu)(zu)過大(da)或過小的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)不宜采用電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)，袋(dai)式(shi)(shi)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)不受粉(fen)(fen)塵(chen)(chen)(chen)(chen)比電(dian)(dian)(dian)阻(zu)(zu)的(de)(de)(de)(de)影響；粉(fen)(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)(de)濃(nong)度(du)和(he)粒(li)度(du)對電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)效率(lv)的(de)(de)(de)(de)影響較為顯著，但對袋(dai)式(shi)(shi)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)(de)(de)影響不顯著；當氣(qi)體的(de)(de)(de)(de)含塵(chen)(chen)(chen)(chen)濃(nong)度(du)較高(gao)時，電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)前宜設置預(yu)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)裝置；袋(dai)式(shi)(shi)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)(de)(de)型式(shi)(shi)、清(qing)灰(hui)方(fang)式(shi)(shi)和(he)過濾風速取決于(yu)粉(fen)(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)(de)性(xing)(xing)(xing)(xing)質（粒(li)徑(jing)、瓢(piao)性(xing)(xing)(xing)(xing)）；濕式(shi)(shi)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)不適(shi)合(he)于(yu)凈化憎(zeng)水性(xing)(xing)(xing)(xing)和(he)水硬性(xing)(xing)(xing)(xing)的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)：粉(fen)(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)(de)真(zhen)密度(du)對重力(li)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)、慣(guan)性(xing)(xing)(xing)(xing)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)和(he)旋風除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)(de)(de)影響顯著；對于(yu)新附性(xing)(xing)(xing)(xing)大(da)的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)，易導致(zhi)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)工作面(mian)貓結或堵塞，因此，不宜采用干(gan)法除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)；粉(fen)(fen)塵(chen)(chen)(chen)(chen)凈化遇水后，能產(chan)生(sheng)可燃或有爆炸危(wei)險的(de)(de)(de)(de)混合(he)物時，不得采用濕式(shi)(shi)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)。

4.根據(ju)壓力損(sun)失與(yu)能耗(hao)

袋式除塵器(qi)的阻力(li)比電除塵器(qi)的阻力(li)大，但從除塵器(qi)整體能耗來(lai)對比，兩者能耗相差不大。

5.根據設備投資和運行(xing)費用

6.節(jie)水與防凍的要求

7.粉塵(chen)和氣體回收利用的要求

粉(fen)塵具有回收(shou)(shou)價(jia)值時，宜(yi)采(cai)用(yong)(yong)干法(fa)除(chu)(chu)塵；當粉(fen)塵具有很高的(de)回收(shou)(shou)價(jia)值時，宜(yi)采(cai)用(yong)(yong)袋式除(chu)(chu)塵器；當凈化后的(de)氣(qi)體需要回收(shou)(shou)利(li)用(yong)(yong)或(huo)凈化后的(de)空(kong)氣(qi)需要再循環利(li)用(yong)(yong)時，宜(yi)采(cai)用(yong)(yong)高效袋式除(chu)(chu)塵器。
