防(fang)(fang)塵(chen)(chen)網(wang)由獨立(li)基礎、鋼結構(gou)支(zhi)撐和擋風(feng)(feng)(feng)(feng)(feng)(feng)(feng)玻(bo)璃三(san)部(bu)(bu)(bu)分(fen)組成(cheng),有(you)效(xiao)地保證了防(fang)(fang)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)網(wang)的(de)(de)防(fang)(fang)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)抑塵(chen)(chen)效(xiao)果(guo)(guo)。*般認為空氣(qi)(qi)(qi)濾(lv)清器在(zai)連接到無孔(kong)板狀墻(qiang)(qiang)體(ti)(ti)時,具(ju)有(you)良好(hao)的(de)(de)抗(kang)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)效(xiao)果(guo)(guo)。直(zhi)接采用(yong)大(da)面(mian)積(ji)墻(qiang)(qiang)體(ti)(ti)無孔(kong)板來承受風(feng)(feng)(feng)(feng)(feng)(feng)(feng)壓(ya),不僅要求(qiu)基礎牢(lao)固,而且不能(neng)有(you)效(xiao)降(jiang)低(di)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)能(neng)。由于(yu)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)是(shi)流(liu)(liu)體(ti)(ti),遇到阻力(li)(li)時,它會(hui)沿墻(qiang)(qiang)上升。通(tong)過(guo)墻(qiang)(qiang)體(ti)(ti)后,風(feng)(feng)(feng)(feng)(feng)(feng)(feng)速(su)迅速(su)增大(da)又迅速(su)減(jian)小,導(dao)致堆(dui)(dui)場(chang)(chang)上部(bu)(bu)(bu)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)速(su)增大(da),堆(dui)(dui)場(chang)(chang)頂部(bu)(bu)(bu)積(ji)塵(chen)(chen)嚴(yan)重(zhong)。受上部(bu)(bu)(bu)流(liu)(liu)體(ti)(ti)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)速(su)的(de)(de)影(ying)響,壁面(mian)內距(ju)離的(de)(de)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)壓(ya)減(jian)小,產生渦流(liu)(liu)(旋風(feng)(feng)(feng)(feng)(feng)(feng)(feng)),但引起堆(dui)(dui)塵(chen)(chen)。只有(you)當部(bu)(bu)(bu)分(fen)空氣(qi)(qi)(qi)通(tong)過(guo)板網(wang)流(liu)(liu)入(ru)空氣(qi)(qi)(qi)過(guo)濾(lv)器內側,以平衡內外(wai)壓(ya)力(li)(li)時,空氣(qi)(qi)(qi)的(de)(de)動(dong)能(neng)才會(hui)損失。因此(ci),沒有(you)孔(kong)的(de)(de)防(fang)(fang)塵(chen)(chen)網(wang)是(shi)無法除(chu)塵(chen)(chen)的(de)(de),只有(you)適(shi)當的(de)(de)透氣(qi)(qi)(qi)性的(de)(de)防(fang)(fang)塵(chen)(chen)網(wang)才能(neng)除(chu)塵(chen)(chen)。合理開放率35-40%。抑風(feng)(feng)(feng)(feng)(feng)(feng)(feng)降(jiang)塵(chen)(chen)網(wang)環(huan)保技術采用(yong)空氣(qi)(qi)(qi)動(dong)力(li)(li)學原理。通(tong)過(guo)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)洞實驗(yan)中,蝴蝶形(xing)(xing)狀的(de)(de)除(chu)塵(chen)(chen)措施處理董事會(hui)形(xing)(xing)成(cheng)了防(fang)(fang)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)網(wang)墻(qiang)(qiang),所以當強(qiang)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)氣(qi)(qi)(qi)流(liu)(liu)從外(wai)面(mian)經過(guo),內在(zai)的(de)(de)*面(mian)墻(qiang)(qiang)上將形(xing)(xing)成(cheng)上下干擾(rao)氣(qi)(qi)(qi)流(liu)(liu),避免流(liu)(liu)的(de)(de)強(qiang)度和渦流(liu)(liu)風(feng)(feng)(feng)(feng)(feng)(feng)(feng),*大(da)限度的(de)(de)損失流(liu)(liu)動(dong)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)的(de)(de)動(dong)能(neng),并形(xing)(xing)成(cheng)外(wai)部(bu)(bu)(bu)強(qiang)風(feng)(feng)(feng)(feng)(feng)(feng)(feng),內部(bu)(bu)(bu)弱風(feng)(feng)(feng)(feng)(feng)(feng)(feng);外(wai)部(bu)(bu)(bu)小風(feng)(feng)(feng)(feng)(feng)(feng)(feng),內部(bu)(bu)(bu)無風(feng)(feng)(feng)(feng)(feng)(feng)(feng),降(jiang)低(di)或消除(chu)含(han)塵(chen)(chen)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)速(su),從而達(da)到抑塵(chen)(chen)、除(chu)塵(chen)(chen)的(de)(de)效(xiao)果(guo)(guo)。*般抑塵(chen)(chen)效(xiao)果(guo)(guo)可達(da)80%-85%。
