除(chu)(chu)塵(chen)器的(de)工(gong)作好(hao)壞(huai)，不僅(jin)直接影響到(dao)除(chu)(chu)塵(chen)系(xi)統的(de)可靠運行，還(huan)關系(xi)到(dao)生(sheng)產系(xi)統的(de)正(zheng)常運行、車間廠區和(he)周邊居民(min)的(de)環境(jing)衛生(sheng)、風機葉片的(de)磨(mo)損和(he)壽命，同時還(huan)涉及有經濟價(jia)值物(wu)料的(de)回收(shou)利用(yong)問(wen)題(ti)。因此(ci)，必(bi)須正(zheng)確地設計、選(xuan)擇與(yu)使用(yong)除(chu)(chu)塵(chen)器。選(xuan)擇除(chu)(chu)塵(chen)器時必(bi)須全面考慮一次投資(zi)和(he)運行費(fei)用(yong)，如除(chu)(chu)塵(chen)效率、壓力損失、可靠性(xing)、一次投資(zi)、占(zhan)地面積、維(wei)修管理等因素，根據煙塵(chen)的(de)理化性(xing)質、特(te)點(dian)和(he)生(sheng)產工(gong)藝的(de)要(yao)求，針對(dui)性(xing)地選(xuan)擇除(chu)(chu)塵(chen)器。

1.根據除(chu)塵效率的要求

2.根據(ju)氣體性(xing)質

選擇除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)時，必須考慮氣(qi)(qi)體的(de)(de)(de)風(feng)(feng)量(liang)、溫(wen)度(du)、成分、濕(shi)度(du)等因素(su)。電(dian)除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)適合于大風(feng)(feng)量(liang)、溫(wen)度(du)<400℃的(de)(de)(de)煙氣(qi)(qi)凈化(hua)；袋(dai)式(shi)除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)適合于溫(wen)度(du)<260℃的(de)(de)(de)煙氣(qi)(qi)凈化(hua)，不受(shou)煙氣(qi)(qi)量(liang)大小(xiao)的(de)(de)(de)限制，當溫(wen)度(du)≥260℃時，煙氣(qi)(qi)應(ying)冷卻降溫(wen)后方(fang)(fang)可(ke)使用袋(dai)式(shi)除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)；袋(dai)式(shi)除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)不宜處理高濕(shi)度(du)和含油污的(de)(de)(de)煙氣(qi)(qi)凈化(hua)；易燃易爆的(de)(de)(de)氣(qi)(qi)體凈化(hua)（如煤氣(qi)(qi)）適合于濕(shi)式(shi)除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)；旋(xuan)風(feng)(feng)除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)的(de)(de)(de)處理風(feng)(feng)量(liang)有(you)限，當風(feng)(feng)量(liang)較大時，可(ke)采用多臺除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)并(bing)聯(lian)的(de)(de)(de)方(fang)(fang)式(shi)；當需(xu)要(yao)同時除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)和凈化(hua)有(you)害氣(qi)(qi)體時，可(ke)考慮采用噴淋塔和旋(xuan)風(feng)(feng)水膜除(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)。< p=“”>

3.根據(ju)粉(fen)塵(chen)性質

粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)性(xing)(xing)(xing)(xing)(xing)質(zhi)包括比電(dian)(dian)阻、粒(li)(li)度(du)、真(zhen)密度(du)、瓢性(xing)(xing)(xing)(xing)(xing)、憎水(shui)性(xing)(xing)(xing)(xing)(xing)和(he)(he)水(shui)硬(ying)(ying)性(xing)(xing)(xing)(xing)(xing)、可燃(ran)、爆炸等(deng)。比電(dian)(dian)阻過大或(huo)過小的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)不宜采(cai)(cai)用電(dian)(dian)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)，袋式(shi)(shi)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)不受粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)比電(dian)(dian)阻的(de)(de)影(ying)(ying)響；粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)的(de)(de)濃度(du)和(he)(he)粒(li)(li)度(du)對電(dian)(dian)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)效率的(de)(de)影(ying)(ying)響較為顯(xian)著(zhu)，但對袋式(shi)(shi)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)的(de)(de)影(ying)(ying)響不顯(xian)著(zhu)；當氣(qi)體的(de)(de)含塵(chen)(chen)(chen)(chen)(chen)(chen)濃度(du)較高時(shi)，電(dian)(dian)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)前(qian)宜設置(zhi)預除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)裝(zhuang)置(zhi)；袋式(shi)(shi)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)的(de)(de)型(xing)式(shi)(shi)、清灰方式(shi)(shi)和(he)(he)過濾(lv)風(feng)速取決于粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)的(de)(de)性(xing)(xing)(xing)(xing)(xing)質(zhi)（粒(li)(li)徑(jing)、瓢性(xing)(xing)(xing)(xing)(xing)）；濕式(shi)(shi)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)不適合于凈化憎水(shui)性(xing)(xing)(xing)(xing)(xing)和(he)(he)水(shui)硬(ying)(ying)性(xing)(xing)(xing)(xing)(xing)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)：粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)的(de)(de)真(zhen)密度(du)對重力除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)、慣性(xing)(xing)(xing)(xing)(xing)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)和(he)(he)旋(xuan)風(feng)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)的(de)(de)影(ying)(ying)響顯(xian)著(zhu)；對于新附(fu)性(xing)(xing)(xing)(xing)(xing)大的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)，易導致(zhi)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)工作面貓(mao)結或(huo)堵塞，因此，不宜采(cai)(cai)用干法(fa)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)；粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)凈化遇水(shui)后，能(neng)產生可燃(ran)或(huo)有(you)爆炸危險的(de)(de)混(hun)合物時(shi)，不得采(cai)(cai)用濕式(shi)(shi)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)。

4.根據壓力損(sun)失(shi)與能耗

袋式除(chu)塵器(qi)的阻(zu)(zu)力比電除(chu)塵器(qi)的阻(zu)(zu)力大，但從(cong)除(chu)塵器(qi)整體(ti)能耗來對比，兩者能耗相差不大。

5.根據設備投資(zi)和運行費用

6.節(jie)水與防凍的要求

水資源(yuan)缺乏的地(di)區不適合采用濕(shi)式除塵器；北方地(di)區存在冬季(ji)凍(dong)結(jie)的問題，盡可能不使用濕(shi)式除塵器。

7.粉塵和氣體回收利(li)用(yong)的要求

粉(fen)塵(chen)具(ju)有回(hui)收價值(zhi)(zhi)時(shi)(shi)，宜(yi)采用(yong)干法(fa)除(chu)(chu)塵(chen)；當粉(fen)塵(chen)具(ju)有很高(gao)的回(hui)收價值(zhi)(zhi)時(shi)(shi)，宜(yi)采用(yong)袋(dai)(dai)式(shi)除(chu)(chu)塵(chen)器；當凈化(hua)后的氣體需要(yao)回(hui)收利用(yong)或凈化(hua)后的空氣需要(yao)再循環(huan)利用(yong)時(shi)(shi)，宜(yi)采用(yong)高(gao)效袋(dai)(dai)式(shi)除(chu)(chu)塵(chen)器。
