等離子體好的不銹鋼煙罩凈化法：近市場上有報道出現等離子體油煙凈化設備的使用。其原理是利用高壓靜電法的同時, 在靜不銹鋼煙罩定制電(dian)場(chang)的(de)前端設(she)置等離(li)子(zi)場(chang),利用其高(gao)能量所(suo)激發(fa)的(de)大(da)量活性自由基對油霧(wu)粒子(zi)進行(xing)降(jiang)解,使其粘度下降(jiang),易于收(shou)集。在(zai)產生等離(li)子(zi)體的(de)同時,高(gao)頻(pin)放電(dian)產生的(de)瞬(shun)時高(gao)能量,能打(da)開(kai)某(mou)些有害氣體的(de)化學鍵而成(cheng)(cheng)為(wei)單(dan)質(zhi)原子(zi)或(huo)無(wu)害分子(zi)。據報道該(gai)技術,去除率(lv)高(gao),處理(li)后(hou)氣體無(wu)異味,維護(hu)方便,但投(tou)資成(cheng)(cheng)本昂貴，技術還不夠成(cheng)(cheng)熟。

不銹鋼風管的制作是采好的不銹鋼煙罩用帶鋼帶狀卷料，通過風管成型機一次咬出咬口骨形，并沿螺旋漸開線軌跡卷成圓形管不銹鋼煙罩定制狀，同時將咬口(kou)縫壓緊，后按需要的長(chang)度(du)切割而成(cheng)。自投放市場(chang)以來，因其本身具有卓越性能(neng)及低廉(lian)的動作成(cheng)本，被廣泛應(ying)用于造船(chuan)、通風、空(kong)調、凈化、橋梁除塵(chen)、機場(chang)、隧(sui)道等(deng)建筑(zhu)行(xing)業。

耐高溫通風好的不銹鋼煙罩管的安裝必須具備一定條件才能進行，對明裝或在技術夾層內安裝的風管，應在通風管道安裝不銹鋼煙罩定制部位(wei)的(de)土(tu)建(jian)工(gong)程(cheng)或主體工(gong)程(cheng)及地評，粉刷完工(gong)以后進行(xing)，如(ru)果(guo)通風管道安裝后，在(zai)進行(xing)土(tu)建(jian)及其他工(gong)作，可能會損壞通風管道，特別是空氣潔凈系統，將會使(shi)管道內受到污染。
