除(chu)塵(chen)(chen)(chen)器的(de)工作好(hao)壞，不(bu)僅直接影響到除(chu)塵(chen)(chen)(chen)系統的(de)可靠運(yun)行，還(huan)關系到生產系統的(de)正(zheng)常運(yun)行、車間廠區和周(zhou)邊居民的(de)環境(jing)衛生、風機(ji)葉片(pian)的(de)磨損和壽命，同時還(huan)涉及有(you)經濟價值(zhi)物(wu)料的(de)回收利用(yong)問題。因此，必須正(zheng)確地設計、選擇(ze)與使用(yong)除(chu)塵(chen)(chen)(chen)器。選擇(ze)除(chu)塵(chen)(chen)(chen)器時必須全面考慮一次投資和運(yun)行費用(yong)，如除(chu)塵(chen)(chen)(chen)效率、壓(ya)力損失、可靠性(xing)、一次投資、占地面積、維修管理(li)等因素，根據煙(yan)塵(chen)(chen)(chen)的(de)理(li)化性(xing)質、特點和生產工藝的(de)要求，針對性(xing)地選擇(ze)除(chu)塵(chen)(chen)(chen)器。

1.根據除塵效率(lv)的要求

所選除(chu)塵器必(bi)須滿足排放標準的(de)要求(qiu)。

不同(tong)的(de)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)具有不同(tong)的(de)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)效率(lv)。對(dui)于運(yun)行(xing)狀(zhuang)況不穩定或(huo)波動較(jiao)大的(de)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)系統，要(yao)注(zhu)意煙氣處理量變化(hua)對(dui)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)效率(lv)的(de)影(ying)響。正(zheng)常運(yun)行(xing)時，除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)效率(lv)高低排序(xu)是：袋(dai)式(shi)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)、電(dian)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)及文丘里除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)、水膜(mo)旋(xuan)風(feng)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)、旋(xuan)風(feng)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)、慣(guan)性(xing)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)、重力除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)

2.根(gen)據氣體(ti)性質

選擇除(chu)(chu)塵(chen)(chen)器(qi)(qi)時(shi)(shi)，必須考(kao)慮(lv)氣(qi)(qi)(qi)體的(de)(de)風(feng)量(liang)、溫度(du)、成分(fen)、濕(shi)度(du)等因素。電除(chu)(chu)塵(chen)(chen)器(qi)(qi)適合于大(da)風(feng)量(liang)、溫度(du)<400℃的(de)(de)煙氣(qi)(qi)(qi)凈化(hua)(hua)；袋式除(chu)(chu)塵(chen)(chen)器(qi)(qi)適合于溫度(du)<260℃的(de)(de)煙氣(qi)(qi)(qi)凈化(hua)(hua)，不(bu)受煙氣(qi)(qi)(qi)量(liang)大(da)小的(de)(de)限(xian)制，當溫度(du)≥260℃時(shi)(shi)，煙氣(qi)(qi)(qi)應冷卻(que)降(jiang)溫后方(fang)可使用(yong)袋式除(chu)(chu)塵(chen)(chen)器(qi)(qi)；袋式除(chu)(chu)塵(chen)(chen)器(qi)(qi)不(bu)宜(yi)處(chu)理高濕(shi)度(du)和(he)含油污的(de)(de)煙氣(qi)(qi)(qi)凈化(hua)(hua)；易(yi)燃易(yi)爆的(de)(de)氣(qi)(qi)(qi)體凈化(hua)(hua)（如煤氣(qi)(qi)(qi)）適合于濕(shi)式除(chu)(chu)塵(chen)(chen)器(qi)(qi)；旋風(feng)除(chu)(chu)塵(chen)(chen)器(qi)(qi)的(de)(de)處(chu)理風(feng)量(liang)有限(xian)，當風(feng)量(liang)較大(da)時(shi)(shi)，可采(cai)用(yong)多臺除(chu)(chu)塵(chen)(chen)器(qi)(qi)并聯(lian)的(de)(de)方(fang)式；當需要同時(shi)(shi)除(chu)(chu)塵(chen)(chen)和(he)凈化(hua)(hua)有害(hai)氣(qi)(qi)(qi)體時(shi)(shi)，可考(kao)慮(lv)采(cai)用(yong)噴(pen)淋塔和(he)旋風(feng)水膜除(chu)(chu)塵(chen)(chen)器(qi)(qi)。< p=“”>

3.根據粉(fen)塵性質

粉塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)性(xing)(xing)(xing)質(zhi)包括比電(dian)(dian)(dian)阻、粒度(du)、真密度(du)、瓢性(xing)(xing)(xing)、憎(zeng)水性(xing)(xing)(xing)和水硬性(xing)(xing)(xing)、可燃、爆炸(zha)等(deng)。比電(dian)(dian)(dian)阻過大或(huo)過小的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)不(bu)(bu)宜采用電(dian)(dian)(dian)除(chu)(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)，袋式(shi)除(chu)(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)不(bu)(bu)受粉塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)比電(dian)(dian)(dian)阻的(de)(de)(de)(de)(de)影(ying)響(xiang)；粉塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)的(de)(de)(de)(de)(de)濃(nong)度(du)和粒度(du)對(dui)(dui)電(dian)(dian)(dian)除(chu)(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)效(xiao)率的(de)(de)(de)(de)(de)影(ying)響(xiang)較(jiao)為顯(xian)著(zhu)，但(dan)對(dui)(dui)袋式(shi)除(chu)(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)(de)(de)(de)影(ying)響(xiang)不(bu)(bu)顯(xian)著(zhu)；當氣體(ti)的(de)(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)濃(nong)度(du)較(jiao)高時，電(dian)(dian)(dian)除(chu)(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)前宜設置(zhi)預(yu)除(chu)(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)裝置(zhi)；袋式(shi)除(chu)(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)(de)(de)(de)型式(shi)、清灰方式(shi)和過濾(lv)風速取決(jue)于(yu)(yu)(yu)粉塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)的(de)(de)(de)(de)(de)性(xing)(xing)(xing)質(zhi)（粒徑、瓢性(xing)(xing)(xing)）；濕式(shi)除(chu)(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)不(bu)(bu)適合于(yu)(yu)(yu)凈(jing)化憎(zeng)水性(xing)(xing)(xing)和水硬性(xing)(xing)(xing)的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)：粉塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)的(de)(de)(de)(de)(de)真密度(du)對(dui)(dui)重力(li)除(chu)(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)、慣性(xing)(xing)(xing)除(chu)(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)和旋風除(chu)(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)(de)(de)(de)影(ying)響(xiang)顯(xian)著(zhu)；對(dui)(dui)于(yu)(yu)(yu)新附性(xing)(xing)(xing)大的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)，易導致除(chu)(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)工作面貓結(jie)或(huo)堵塞，因此，不(bu)(bu)宜采用干法(fa)除(chu)(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)；粉塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)凈(jing)化遇水后，能產生(sheng)可燃或(huo)有(you)爆炸(zha)危險的(de)(de)(de)(de)(de)混合物時，不(bu)(bu)得采用濕式(shi)除(chu)(chu)(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)。

4.根據(ju)壓力(li)損失與能耗(hao)

袋(dai)式除塵器(qi)的(de)阻(zu)力比電除塵器(qi)的(de)阻(zu)力大(da)，但(dan)從除塵器(qi)整體能(neng)耗來對比，兩者能(neng)耗相差不大(da)。

5.根(gen)據設備投資和運行(xing)費(fei)用(yong)

6.節水與(yu)防凍的要求

水(shui)資源(yuan)缺乏的地區不適合(he)采用濕式除(chu)塵(chen)(chen)器；北方地區存在冬季凍(dong)結的問(wen)題，盡可(ke)能不使用濕式除(chu)塵(chen)(chen)器。

7.粉塵(chen)和氣體(ti)回收(shou)利用的要求

粉塵(chen)(chen)具有(you)回收價(jia)值(zhi)時(shi)，宜采(cai)用(yong)(yong)干法除(chu)塵(chen)(chen)；當粉塵(chen)(chen)具有(you)很高(gao)的(de)回收價(jia)值(zhi)時(shi)，宜采(cai)用(yong)(yong)袋式除(chu)塵(chen)(chen)器；當凈(jing)化后的(de)氣(qi)體需(xu)要回收利(li)用(yong)(yong)或凈(jing)化后的(de)空氣(qi)需(xu)要再循環(huan)利(li)用(yong)(yong)時(shi)，宜采(cai)用(yong)(yong)高(gao)效袋式除(chu)塵(chen)(chen)器。
