高壓靜電重正規白鐵風管慶油煙凈化方法：高壓靜電方法是由220kv電壓通過變壓器變壓至上萬伏，然后經整流器轉換白鐵風管安裝成(cheng)直流(liu)電(dian)，在兩極(ji)(ji)板間(jian)構(gou)成(cheng)一個強電(dian)場，使煙氣中(zhong)顆(ke)(ke)粒(li)(li)荷電(dian)，荷電(dian)的油煙霧顆(ke)(ke)粒(li)(li)物在電(dian)極(ji)(ji)間(jian)受重力、電(dian)極(ji)(ji)引力和(he)風場動力做用.由于顆(ke)(ke)粒(li)(li)物的荷電(dian)量隨粒(li)(li)徑(jing)的增(zeng)長(chang)而增(zeng)大，大顆(ke)(ke)粒(li)(li)受電(dian)場力的作用大，其對(dui)氣溶膠(jiao)狀態(tai)污染(ran)物的去除率相對(dui)較(jiao)高(gao)，可達80%-90%，但該法造(zao)價相對(dui)較(jiao)高(gao)，在運行維護(hu)方面(mian),相比(bi)機械(xie)式(shi)(shi)靜電(dian)式(shi)(shi)較(jiao)為(wei)簡單，而在設(she)備(bei)價格方面(mian),靜電(dian)式(shi)(shi)投入成(cheng)本(ben)相比(bi)機械(xie)式(shi)(shi)要大。綜合比(bi)較(jiao)而言,靜電(dian)式(shi)(shi)凈化(hua)設(she)備(bei)優于機械(xie)式(shi)(shi)凈化(hua)設(she)備(bei)。

從重慶白鐵加正規白鐵風管工廠了解到，白鐵皮要比馬口鐵耐用，馬口鐵碰破一點，很快會爛掉;可是白鐵皮即使碰白鐵風管安裝破一大塊，也(ye)不容易(yi)被銹蝕。這是因為鋅的(de)化學性質比鐵活潑，當(dang)外(wai)界的(de)空氣和(he)水份向白鐵皮(pi)“進攻”時(shi)，鋅首先與氧氣化合(he)，而保護(hu)了鐵的(de)安全(quan)。 金屬鋅除(chu)了用來制(zhi)造(zao)白鐵皮(pi)外(wai)，也(ye)用來制(zhi)造(zao)干電(dian)池的(de)外(wai)殼。不過干電(dian)池外(wai)殼的(de)鋅是較純的(de)。此外(wai)，鋅也(ye)與銅(tong)制(zhi)成銅(tong)鋅合(he)金——黃銅(tong)。
