機械重慶油煙正規風管加工凈化方法：是采用過濾、旋風離心、活性炭吸附等收集油煙霧．這種處理方法的處理效果與風管加工定制其設(she)計(ji)、控制(zhi)參數及(ji)使(shi)用(yong)的材料(liao)(liao)有關．采用(yong)過(guo)濾(lv)(lv)(lv)的方式處理(li)油(you)煙霧(wu)，是在油(you)煙霧(wu)通(tong)過(guo)格(ge)柵、油(you)霧(wu)網罩(zhao)等時(shi)通(tong)過(guo)改變氣(qi)(qi)(qi)流(liu)(liu)方向而使(shi)油(you)煙霧(wu)顆粒靠慣性(xing)與碰(peng)撞從氣(qi)(qi)(qi)流(liu)(liu)中分(fen)離流(liu)(liu)入油(you)槽(cao)．過(guo)濾(lv)(lv)(lv)方式采用(yong)的濾(lv)(lv)(lv)料(liao)(liao)大多(duo)為(wei)親油(you)性(xing)的高分(fen)子(zi)材料(liao)(liao)，成本低，這種方式對氣(qi)(qi)(qi)溶膠的去(qu)除率為(wei)40%—70%，且對氣(qi)(qi)(qi)味(wei)的凈化有明顯作(zuo)用(yong)．但一般剛開始安裝時(shi)吸附效果好(hao)，隨著(zhu)油(you)煙霧(wu)的附著(zhu)，吸附能力會逐漸(jian)減弱(ruo)，必(bi)須經常更換濾(lv)(lv)(lv)料(liao)(liao)，故運(yun)行成本高。

工業中的正規風管加工主要有： (1)白鐵管道類：白風管加工定制鐵(tie)厚(hou)鐵(tie)各(ge)(ge)種排(pai)(pai)氣(qi)，排(pai)(pai)風、吸塵管(guan)(guan)道(dao)，中央(yang)空調(diao)冷(leng)氣(qi)管(guan)(guan)，廚(chu)房(fang)抽油(you)煙(yan)管(guan)(guan)道(dao)，保溫管(guan)(guan)、烤漆(qi)爐抽煙(yan)煙(yan)罩(zhao)。 (2)白鐵(tie)工(gong)(gong)(gong)程類：酒店餐館超市工(gong)(gong)(gong)程、車間換(huan)氣(qi)工(gong)(gong)(gong)程、工(gong)(gong)(gong)業(廠)排(pai)(pai)風(通風)凈化工(gong)(gong)(gong)程、水(shui)簾(lian)降溫工(gong)(gong)(gong)程。 (3)對外(wai)加工(gong)(gong)(gong)：剪板、折(zhe)板、沖壓(ya)、液壓(ya)。 (4)來(lai)料加工(gong)(gong)(gong)或(huo)定做的(de)(de)(de)(de)生產銷售： 各(ge)(ge)種五金(jin)白鐵(tie)制品(pin)(pin)、鋁(lv)板、不銹(xiu)鋼及各(ge)(ge)種方(fang)圓制品(pin)(pin)、水(shui)濂(lian)柜、不銹(xiu)鋼工(gong)(gong)(gong)作(zuo)臺、貨架、水(shui)箱、吸塵桶。 我(wo)(wo)們在(zai)說說白鐵(tie)煙(yan)囪的(de)(de)(de)(de)加工(gong)(gong)(gong)流程：根據(ju)客(ke)(ke)戶(hu)的(de)(de)(de)(de)需(xu)求(qiu)（圓形還是方(fang)形），用專(zhuan)業的(de)(de)(de)(de)設備進行(xing)定型(xing)，然后壓(ya)邊，繼(ji)而(er)對縫合(he)處密(mi)封處理(li)。說到(dao)這里(li)，有些(xie)人就有些(xie)不賴煩了，我(wo)(wo)們主要是講(jiang)白鐵(tie)的(de)(de)(de)(de)好(hao)處，怎(zen)么說到(dao)這里(li)了呢(ni)，其實不然，我(wo)(wo)們在(zai)了解(jie)它好(hao)處的(de)(de)(de)(de)同(tong)時，基礎(chu)是需(xu)要了解(jie)的(de)(de)(de)(de)，因為(wei)那(nei)些(xie)好(hao)處都是從(cong)白鐵(tie)的(de)(de)(de)(de)材(cai)質而(er)言的(de)(de)(de)(de)。 一(yi)、耐高溫：白鐵(tie)所承受的(de)(de)(de)(de)溫度(du)是35℃-600℃，還可以(yi)根據(ju)客(ke)(ke)戶(hu)需(xu)求(qiu)更高； 二、方(fang)、圓隨用戶(hu)而(er)定； 三、工(gong)(gong)(gong)作(zuo)壓(ya)力(li)強：一(yi)般在(zai)400mmWG，也(ye)可根據(ju)客(ke)(ke)戶(hu)需(xu)求(qiu)更高； 四、美觀、大方(fang)，可根據(ju)客(ke)(ke)戶(hu)的(de)(de)(de)(de)樣式制作(zuo)（白鐵(tie)的(de)(de)(de)(de)可塑性更強）； 除以(yi)上之外(wai)還有耐酸堿、阻燃、耐磨、耐拉等功能(neng)(neng)。有良好(hao)的(de)(de)(de)(de)防火性能(neng)(neng)和良好(hao)的(de)(de)(de)(de)機械強度(du)。 白鐵(tie)在(zai)很多地方(fang)都能(neng)(neng)用到(dao)，工(gong)(gong)(gong)廠廠房(fang)、電子設備、酒店、冶金(jin)、制冷(leng)、高氣(qi)體、通風換(huan)氣(qi)、環(huan)保通風工(gong)(gong)(gong)程之抽放煙(yan)霧、濕氣(qi)、塵埃等，真可謂用途多多。
