廚房排煙管道正規鍍鋅風管的設計和安裝不合理，往往會造成廚房排煙不通暢，直接影響油煙凈化器的使用，其主要鍍鋅風管定制原(yuan)因(yin)有(you)以(yi)(yi)下(xia)幾種： 一(yi)(yi)、主(zhu)排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)道(dao)(dao)(dao)(dao)(dao)通(tong)(tong)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)面積(ji)(ji)不(bu)(bu)(bu)夠 迅速(su)(su)排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)防止串味(wei)(wei)看(kan)廚(chu)房(fang)(fang)排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)道(dao)(dao)(dao)(dao)(dao)安(an)裝(zhuang)(zhuang) 根據工(gong)程經驗，排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)主(zhu)管(guan)道(dao)(dao)(dao)(dao)(dao)內(nei)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)速(su)(su)不(bu)(bu)(bu)能(neng)超過15m/s，否則在(zai)運行一(yi)(yi)個(ge)時(shi)期以(yi)(yi)后(hou)很容易造成排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)系統不(bu)(bu)(bu)通(tong)(tong)暢(chang)(chang)。在(zai)油(you)(you)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)凈化器(qi)(qi)的(de)(de)(de)(de)運行實踐中(zhong)，大部分案(an)例都(dou)是因(yin)排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)道(dao)(dao)(dao)(dao)(dao)通(tong)(tong)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)面積(ji)(ji)不(bu)(bu)(bu)足引起的(de)(de)(de)(de)不(bu)(bu)(bu)通(tong)(tong)暢(chang)(chang)，管(guan)道(dao)(dao)(dao)(dao)(dao)內(nei)氣體的(de)(de)(de)(de)流速(su)(su)都(dou)在(zai)15m/s以(yi)(yi)上(shang)。 二、管(guan)道(dao)(dao)(dao)(dao)(dao)截面積(ji)(ji)變(bian)小 迅速(su)(su)排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)防止串味(wei)(wei) 看(kan)廚(chu)房(fang)(fang)排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)道(dao)(dao)(dao)(dao)(dao)安(an)裝(zhuang)(zhuang) 排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)道(dao)(dao)(dao)(dao)(dao)由(you)(you)于要穿(chuan)過建筑梁(liang)而使(shi)管(guan)道(dao)(dao)(dao)(dao)(dao)通(tong)(tong)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)截面積(ji)(ji)變(bian)小，截面上(shang)阻力增(zeng)加，造成氣流不(bu)(bu)(bu)通(tong)(tong)暢(chang)(chang)。 三、排(pai)(pai)(pai)管(guan)道(dao)(dao)(dao)(dao)(dao)使(shi)用(yong)后(hou)積(ji)(ji)聚(ju)物堆(dui)積(ji)(ji) 迅速(su)(su)排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)防止串味(wei)(wei) 看(kan)廚(chu)房(fang)(fang)排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)道(dao)(dao)(dao)(dao)(dao)安(an)裝(zhuang)(zhuang) 排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)道(dao)(dao)(dao)(dao)(dao)在(zai)穿(chuan)過建筑梁(liang)或躲(duo)避(bi)其(qi)它設備管(guan)道(dao)(dao)(dao)(dao)(dao)時(shi)，排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)道(dao)(dao)(dao)(dao)(dao)中(zhong)的(de)(de)(de)(de)一(yi)(yi)段(duan)(duan)會(hui)低于整體排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)道(dao)(dao)(dao)(dao)(dao)平面，在(zai)使(shi)用(yong)一(yi)(yi)段(duan)(duan)時(shi)間后(hou)，由(you)(you)于油(you)(you)水(shui)混合物會(hui)積(ji)(ji)聚(ju)在(zai)較(jiao)低的(de)(de)(de)(de)那段(duan)(duan)排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)道(dao)(dao)(dao)(dao)(dao)中(zhong)，直接影響排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)通(tong)(tong)暢(chang)(chang)。 四、低層(ceng)排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)不(bu)(bu)(bu)順暢(chang)(chang) 不(bu)(bu)(bu)同樓層(ceng)的(de)(de)(de)(de)廚(chu)房(fang)(fang)油(you)(you)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)通(tong)(tong)過同一(yi)(yi)主(zhu)管(guan)道(dao)(dao)(dao)(dao)(dao)排(pai)(pai)(pai)出，離(li)出口(kou)近的(de)(de)(de)(de)樓層(ceng)廚(chu)房(fang)(fang)排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)效(xiao)果較(jiao)好，而較(jiao)低樓層(ceng)的(de)(de)(de)(de)廚(chu)房(fang)(fang)排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)不(bu)(bu)(bu)通(tong)(tong)暢(chang)(chang)。 五、建議配(pei)備排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji) 對于油(you)(you)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)較(jiao)大的(de)(de)(de)(de)廚(chu)房(fang)(fang)，建議還配(pei)備一(yi)(yi)個(ge)排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)。常(chang)用(yong)的(de)(de)(de)(de)排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)有(you)軸(zhou)流風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)、風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)箱(xiang)和離(li)心(xin)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)3種。 軸(zhou)流風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)：以(yi)(yi)前(qian)應用(yong)較(jiao)多，但由(you)(you)于全壓(ya)小，在(zai)安(an)裝(zhuang)(zhuang)油(you)(you)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)凈化器(qi)(qi)后(hou)很少應用(yong)。 風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)箱(xiang)：全壓(ya)中(zhong)等，風(feng)(feng)(feng)(feng)(feng)(feng)(feng)量(liang)可以(yi)(yi)調(diao)節(jie)，且噪聲較(jiao)低，常(chang)在(zai)集煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)罩(zhao)距油(you)(you)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)排(pai)(pai)(pai)放口(kou)距離(li)中(zhong)等的(de)(de)(de)(de)廚(chu)房(fang)(fang)排(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)系統中(zhong)選(xuan)用(yong)。 離(li)心(xin)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)：全壓(ya)和風(feng)(feng)(feng)(feng)(feng)(feng)(feng)量(liang)都(dou)可以(yi)(yi)調(diao)節(jie)，但由(you)(you)于噪聲較(jiao)大，常(chang)需要做降噪處(chu)理。當廚(chu)房(fang)(fang)位于建筑物的(de)(de)(de)(de)底部時(shi)其(qi)排(pai)(pai)(pai)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)宜(yi)安(an)放在(zai)屋頂(ding)，一(yi)(yi)般(ban)選(xuan)擇離(li)心(xin)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)。

標準直管由流水正規鍍鋅風管線上直接壓制成連體法蘭。非標直管、彎頭、三通、四通、配件等下料后，在單機設備上完成鍍鋅風管定制TDF法(fa)蘭(lan)成(cheng)(cheng)型(xing)。法(fa)蘭(lan)角(jiao)由模具直接(jie)(jie)沖壓成(cheng)(cheng)型(xing)，安(an)裝時卡(ka)在四(si)個(ge)角(jiao)即可。法(fa)蘭(lan)間的(de)連接(jie)(jie)用(yong)法(fa)蘭(lan)卡(ka)，由鍍(du)鋅鋼板制作，經(jing)法(fa)蘭(lan)卡(ka)成(cheng)(cheng)型(xing)機成(cheng)(cheng)型(xing)后切(qie)割成(cheng)(cheng)統一的(de)尺寸供安(an)裝連接(jie)(jie)使用(yong)。TDF共板法(fa)蘭(lan)因與管道鋼板連成(cheng)(cheng)一體，不(bu)必像(xiang)角(jiao)鋼法(fa)蘭(lan)般打孔鉚接(jie)(jie)，在兩節(jie)管道的(de)連接(jie)(jie)上(shang)用(yong)專用(yong)法(fa)蘭(lan)卡(ka)，四(si)角(jiao)加90度法(fa)蘭(lan)角(jiao)后用(yong)螺栓連接(jie)(jie)。

濕式處理正規鍍鋅風管法：濕式處理法是將油煙霧用水霧噴淋（在水中加入一些化學試劑增加吸收），水油接觸的鍍鋅風管定制表面積增大(da)，水對油(you)煙(yan)霧吸(xi)(xi)收能力增強(qiang)，從而達到去除油(you)煙(yan)霧粒子的目的．采用(yong)(yong)濕(shi)式處理法的關鍵在于(yu)吸(xi)(xi)收液對油(you)煙(yan)霧的吸(xi)(xi)收性能，該法凈(jing)化效率(lv)較(jiao)高，能降低油(you)煙(yan)霧溫(wen)度，加(jia)入適當的化學試劑(ji)，還可(ke)以同時去除辣椒、胡椒等(deng)刺激(ji)性味道．但此法大(da)多會產生二次(ci)污染(ran)，初期(qi)投(tou)資較(jiao)高，耗(hao)電，且需頻繁加(jia)水，洗滌劑(ji)、吸(xi)(xi)收劑(ji)用(yong)(yong)量大(da)，費(fei)用(yong)(yong)較(jiao)高，洗滌液須進行(xing)處理，否則會出現二次(ci)污染(ran)問(wen)題。目前(qian)此法在國內市場(chang)上較(jiao)少采用(yong)(yong)。

近年來，隨著正規鍍鋅風管國家和地方相繼出臺了一系列治理飲食業油煙污染的排放標準和法規，刺激了市場需求，并鍍鋅風管定制相應地形成了一個很(hen)有潛力的(de)飲食(shi)業(ye)油煙凈(jing)化(hua)設(she)備市場(chang)。通過(guo)對(dui)市場(chang)上流行的(de)油煙凈(jing)化(hua)設(she)備進行分析，按技(ji)術(shu)原理大致可以分為(wei)四(si)類：機(ji)械式重慶(qing)油煙凈(jing)化(hua)設(she)備、靜電(dian)式重慶(qing)油煙凈(jing)化(hua)設(she)備、濕(shi)式重慶(qing)油煙凈(jing)化(hua)設(she)備、等離子(zi)重慶(qing)油煙凈(jing)化(hua)法和復合式重慶(qing)油煙凈(jing)化(hua)設(she)備機(ji)械方(fang)法。
