過濾器設備
靜電式空氣過濾器由美國加利(li)福尼亞大學penny博士于1935年較先設(she)計(ji)的。利(li)用陽極電(dian)暈放電(dian)原理，使空(kong)氣中的粉塵帶(dai)上(shang)正電(dian)荷，然后借助(zhu)庫侖力作用，將帶(dai)電(dian)粒子捕集(ji)在(zai)集(ji)塵裝置(zhi)上(shang)，達到除(chu)塵凈化空(kong)氣的目(mu)的。
靜(jing)電式(shi)空(kong)(kong)氣(qi)過濾器(qi)(qi)(qi)的(de)特點就是為(wei)集(ji)塵(chen)效率高，有些空(kong)(kong)氣(qi)凈(jing)化器(qi)(qi)(qi)的(de)收(shou)塵(chen)效率高達80%以上，另(ling)外還能(neng)捕集(ji)微(wei)小(xiao)粒子(zi)(0.01μm～0.10μm)，同時集(ji)塵(chen)裝(zhuang)置(zhi)的(de)壓力(li)損失(shi)少。它由離子(zi)化裝(zhuang)置(zhi)、集(ji)塵(chen)裝(zhuang)置(zhi)、送風機和電源等(deng)(deng)部(bu)件構(gou)成。這(zhe)種(zhong)凈(jing)化器(qi)(qi)(qi)實際上是一(yi)種(zhong)小(xiao)型靜(jing)電式(shi)空(kong)(kong)氣(qi)過濾器(qi)(qi)(qi)，對粒徑較大的(de)顆粒污(wu)染物的(de)凈(jing)化效果較好，但是無法凈(jing)化氣(qi)態污(wu)染物，同時，還會(hui)產(chan)生臭(chou)氧等(deng)(deng)二次污(wu)染物。
一(yi)項調查表明，國內(nei)城市居民每(mei)天在(zai)室(shi)內(nei)的時(shi)間(jian)長(chang)達(da)21.53小(xiao)時(shi)，占全(quan)天時(shi)間(jian)的90%。因此，人體健(jian)康(kang)與室(shi)內(nei)空(kong)氣質量(liang)關系密切，“健(jian)康(kang)呼吸(xi)”已成為迫切需要(yao)。靜電(dian)式(shi)空(kong)氣過濾器該如何(he)選購?選購靜電(dian)式(shi)空(kong)氣過濾器應(ying)該注意(yi)以下事項：
(一)濾(lv)材：好的過(guo)濾(lv)材料(如HEPA高(gao)密度濾(lv)材)吸附0.3微(wei)米(mi)以(yi)上(shang)污染(ran)物的能力高(gao)達99.9%以(yi)上(shang);如果(guo)室內煙塵污染(ran)較(jiao)重，可選擇除塵效果(guo)較(jiao)佳的空氣凈(jing)化器(qi)。
(二)凈化(hua)效率：房間較(jiao)大，應選(xuan)擇單(dan)位(wei)凈化(hua)風(feng)(feng)量大的(de)空氣凈化(hua)器(qi);例如15平方(fang)米(mi)的(de)房間應選(xuan)擇單(dan)位(wei)凈化(hua)風(feng)(feng)量在120立方(fang)米(mi)/小時的(de)空氣凈化(hua)器(qi)。
(三(san))使(shi)用壽命：隨著(zhu)凈化(hua)過濾膽趨于飽和，凈化(hua)器的吸(xi)附能力將下降，所以消費者(zhe)應選擇具有(you)再(zai)生功能的凈化(hua)過濾膽，以延長其壽命。
(四)房(fang)間(jian)格局(ju)(ju)是否影響(xiang)凈(jing)化效(xiao)果：空氣凈(jing)化器的進(jin)出風(feng)口(kou)有360度環形(xing)設(she)計的，也有單(dan)向(xiang)進(jin)出風(feng)的，若在產品(pin)擺放(fang)上不受房(fang)間(jian)格局(ju)(ju)限制，則應選擇環形(xing)進(jin)出風(feng)設(she)計的產品(pin)。
(五)需(xu)求：根據需(xu)要(yao)凈(jing)化(hua)(hua)(hua)的(de)污染物種類選擇空氣(qi)凈(jing)化(hua)(hua)(hua)器，HEPA對煙(yan)塵(chen)、懸浮(fu)顆(ke)粒、細菌、病毒有很強(qiang)的(de)凈(jing)化(hua)(hua)(hua)功(gong)能，催化(hua)(hua)(hua)活性炭對異味、有害氣(qi)體凈(jing)化(hua)(hua)(hua)效果較佳。
(六)售(shou)后(hou)服務：凈化濾芯失效后(hou)需到廠家更(geng)換，所以消費者應選(xuan)擇售(shou)后(hou)服務完(wan)善的廠家生產(chan)的產(chan)品。
現在(zai)靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)式(shi)空氣過濾(lv)器主要有3種類(lei)型：電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離極板型、帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)介質非電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離型和(he)帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)介質電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離型，且均(jun)采用(yong)正電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，因為(wei)(wei)正電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)比負(fu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)產(chan)生的(de)(de)臭(chou)氧濃度(du)(du)低。但在(zai)相同電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓情況(kuang)下，正電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)低，凈(jing)(jing)化(hua)效率低，致使分(fen)布(bu)在(zai)空氣中的(de)(de)正離子濃度(du)(du)提(ti)高。為(wei)(wei)了(le)進一(yi)步減小(xiao)臭(chou)氧濃度(du)(du)、降低凈(jing)(jing)化(hua)器的(de)(de)工作電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，目前采用(yong)兩(liang)級(ji)負(fu)離子空氣凈(jing)(jing)化(hua)器，前級(ji)為(wei)(wei)常規空氣凈(jing)(jing)化(hua)器，后級(ji)為(wei)(wei)臭(chou)氧控制器，但這樣卻(que)使成本和(he)運行費(fei)用(yong)提(ti)高。此產(chan)品(pin)屬于逐步淘汰產(chan)品(pin)。
今(jin)天我們主要是從靜電式空氣(qi)過濾器如何購買以(yi)及注(zhu)意事(shi)項進(jin)行的(de)一些(xie)介(jie)紹，希望通過我們的(de)介(jie)紹，能夠給大家帶來(lai)一定的(de)幫(bang)助。同時(shi)(shi)，如果大家還(huan)有(you)不懂的(de)地(di)方，可以(yi)隨時(shi)(shi)來(lai)電咨詢。
