靜電除塵設備

靜電(dian)(dian)(dian)(dian)(dian)除塵是氣(qi)(qi)體除塵方法(fa)的(de)一種。含塵氣(qi)(qi)體經過高壓靜電(dian)(dian)(dian)(dian)(dian)場時被電(dian)(dian)(dian)(dian)(dian)離，塵粒(li)與(yu)負離子結合(he)帶上負電(dian)(dian)(dian)(dian)(dian)后(hou)，趨向陽極表(biao)面(mian)放電(dian)(dian)(dian)(dian)(dian)而沉(chen)積。常用(yong)于(yu)(yu)以煤(mei)為燃料的(de)工廠、電(dian)(dian)(dian)(dian)(dian)站，收(shou)集煙氣(qi)(qi)中的(de)煤(mei)灰和粉塵，冶(ye)金(jin)中用(yong)于(yu)(yu)收(shou)集錫、鋅(xin)、鉛、鋁(lv)等的(de)氧化物。也可用(yong)于(yu)(yu)家居(ju)的(de)除塵滅菌(jun)：產(chan)品空氣(qi)(qi)電(dian)(dian)(dian)(dian)(dian)離后(hou)，由于(yu)(yu)連鎖反(fan)應，在極間運動的(de)離子數大(da)(da)大(da)(da)增加，表(biao)現(xian)為極間的(de)電(dian)(dian)(dian)(dian)(dian)流(稱之為電(dian)(dian)(dian)(dian)(dian)暈電(dian)(dian)(dian)(dian)(dian)流)急劇增加，空氣(qi)(qi)成(cheng)(cheng)了導(dao)體，高強電(dian)(dian)(dian)(dian)(dian)壓捕獲附(fu)帶細菌(jun)顆粒(li)，瞬間導(dao)電(dian)(dian)(dian)(dian)(dian)擊穿由蛋白質組成(cheng)(cheng)的(de)細胞(bao)壁，達到殺滅細菌(jun)吸附(fu)除塵的(de)目的(de)。此類除塵設(she)備廣泛用(yong)于(yu)(yu)冶(ye)金(jin)、礦山、化工、制(zhi)藥、發電(dian)(dian)(dian)(dian)(dian)、冶(ye)煉等行業。
