pm2.5指數近兩年來成為社會關注的焦點,pm2.5指的是空氣中粒徑小于或等于2.5微米的顆粒物質,因為這種物質能夠進入到肺部,所以也被叫做可入肺顆粒物。隨著空氣污染問題的日漸嚴重,我國多地pm2.5指數頻繁報表,給人們的生活帶來了很大不便,pm2.5空氣過濾器具有良好的過(guo)(guo)濾(lv)效率,能(neng)夠有效過(guo)(guo)濾(lv)空(kong)氣(qi)中的污染物質,下面我(wo)們將為大家介紹一(yi)下pm2.5空(kong)氣(qi)過(guo)(guo)濾(lv)器中使用(yong)了哪些過(guo)(guo)濾(lv)技術。
1.靜電(dian)除塵技術(shu)
靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)技(ji)術在(zai)過(guo)(guo)(guo)濾過(guo)(guo)(guo)程中(zhong)利用高(gao)壓靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)使空氣(qi)中(zhong)的(de)(de)灰(hui)塵(chen)(chen)顆(ke)粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian),然后在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的(de)(de)作用下被捕集(ji)過(guo)(guo)(guo)濾。當含有(you)粉(fen)(fen)塵(chen)(chen)顆(ke)粒(li)的(de)(de)空氣(qi)通過(guo)(guo)(guo)pm2.5空氣(qi)過(guo)(guo)(guo)濾器中(zhong)的(de)(de)高(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)時,由于電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)陰極發生電(dian)(dian)(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)(dian)(dian),氣(qi)體將(jiang)會被電(dian)(dian)(dian)(dian)(dian)(dian)離,在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的(de)(de)作用下,開始向陽極板移動,在(zai)運動過(guo)(guo)(guo)程中(zhong),帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)體與粉(fen)(fen)塵(chen)(chen)顆(ke)粒(li)相碰,從而(er)將(jiang)電(dian)(dian)(dian)(dian)(dian)(dian)荷傳遞(di)給粉(fen)(fen)塵(chen)(chen)顆(ke)粒(li),然后帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)粉(fen)(fen)塵(chen)(chen)顆(ke)粒(li)也將(jiang)向陽極板移動,終被捕集(ji)過(guo)(guo)(guo)濾。
2.活性炭技術
活(huo)性(xing)(xing)(xing)炭技術的(de)(de)應用(yong)非常,這種過(guo)濾(lv)(lv)技術雖然過(guo)濾(lv)(lv)精度較低,但是能夠有(you)(you)效吸收空(kong)(kong)氣中(zhong)的(de)(de)異味(wei)或可揮發(fa)性(xing)(xing)(xing)有(you)(you)毒、有(you)(you)害氣體。活(huo)性(xing)(xing)(xing)炭也(ye)被(bei)稱為活(huo)性(xing)(xing)(xing)炭黑,在其內部(bu)分(fen)(fen)布著密集復雜的(de)(de)孔(kong)隙(xi)結構(gou),當(dang)空(kong)(kong)氣中(zhong)的(de)(de)有(you)(you)害氣體分(fen)(fen)子(zi)(zi)進(jin)入(ru)pm2.5空(kong)(kong)氣過(guo)濾(lv)(lv)器之后(hou),將會被(bei)活(huo)性(xing)(xing)(xing)炭濾(lv)(lv)網中(zhong)的(de)(de)空(kong)(kong)隙(xi)結構(gou)牢牢吸附,然后(hou)在分(fen)(fen)子(zi)(zi)間(jian)作用(yong)力(li)的(de)(de)吸引之下,越來越多(duo)的(de)(de)氣體分(fen)(fen)子(zi)(zi)將會被(bei)吸附,知道孔(kong)隙(xi)結構(gou)被(bei)完全填滿(man)。
3.HEPA技術
HEPA濾(lv)網(wang)時國際(ji)公認好的(de)過(guo)濾(lv)材料之一,也是pm2.5空氣過(guo)濾(lv)器(qi)中的(de)重要組成(cheng)部分。HEPA濾(lv)網(wang)由直徑細小的(de)有機纖維交織而成(cheng),具有容塵量大(da)、凈化效率高(gao)等特(te)點,即(ji)使面對粒徑在(zai)0.3微米(mi)左右(you)的(de)微粒,也能夠(gou)達到99.97%的(de)過(guo)濾(lv)效率,過(guo)濾(lv)pm2.5當然也不在(zai)話下。
PM2.5粒徑小,并且含有(you)大量的(de)有(you)毒(du)、有(you)害物質(zhi),對人體健康與很(hen)大影響,因(yin)此(ci)使(shi)用pm2.5空(kong)氣(qi)過濾(lv)器(qi)非常有(you)必要,為了保障過濾(lv)效率,消(xiao)費(fei)者在選(xuan)擇pm2.5空(kong)氣(qi)過濾(lv)器(qi)時(shi)要從自身實(shi)際需求(qiu)出(chu)發,以免造成(cheng)不必要的(de)浪費(fei)。
