濾筒

濾(lv)(lv)(lv)(lv)(lv)筒(tong)(tong)(tong)(tong)(tong)，顧名思義，是一種用(yong)來進(jin)行過(guo)(guo)濾(lv)(lv)(lv)(lv)(lv)的(de)(de)筒(tong)(tong)(tong)(tong)(tong)狀(zhuang)(zhuang)元件，一般分(fen)為用(yong)來過(guo)(guo)濾(lv)(lv)(lv)(lv)(lv)氣體(ti)介質和(he)過(guo)(guo)濾(lv)(lv)(lv)(lv)(lv)液體(ti)介質的(de)(de)濾(lv)(lv)(lv)(lv)(lv)筒(tong)(tong)(tong)(tong)(tong)。過(guo)(guo)濾(lv)(lv)(lv)(lv)(lv)液體(ti)狀(zhuang)(zhuang)介質的(de)(de)濾(lv)(lv)(lv)(lv)(lv)筒(tong)(tong)(tong)(tong)(tong)般安(an)(an)(an)裝(zhuang)于(yu)(yu)(yu)管道過(guo)(guo)濾(lv)(lv)(lv)(lv)(lv)器之內，外(wai)形常見錐狀(zhuang)(zhuang)，故(gu)又稱錐形濾(lv)(lv)(lv)(lv)(lv)網。濾(lv)(lv)(lv)(lv)(lv)筒(tong)(tong)(tong)(tong)(tong)屬于(yu)(yu)(yu)表面(mian)過(guo)(guo)濾(lv)(lv)(lv)(lv)(lv)元件，它是利(li)用(yong)濾(lv)(lv)(lv)(lv)(lv)材表面(mian)形成(cheng)的(de)(de)微小透氣組織阻擋掉氣體(ti)中(zhong)的(de)(de)粒狀(zhuang)(zhuang)物(wu)質。濾(lv)(lv)(lv)(lv)(lv)筒(tong)(tong)(tong)(tong)(tong)脈沖除(chu)塵(chen)(chen)(chen)器的(de)(de)安(an)(an)(an)裝(zhuang)方式(shi)有三種：垂直、傾(qing)斜、水(shui)(shui)平(ping)安(an)(an)(an)裝(zhuang)。濾(lv)(lv)(lv)(lv)(lv)筒(tong)(tong)(tong)(tong)(tong)垂直安(an)(an)(an)裝(zhuang)，脈沖清(qing)灰時，粉(fen)塵(chen)(chen)(chen)易清(qing)落(luo)沉降至灰斗，效果好。傾(qing)斜安(an)(an)(an)裝(zhuang)時，濾(lv)(lv)(lv)(lv)(lv)筒(tong)(tong)(tong)(tong)(tong)上(shang)下相(xiang)疊(die)，三耳濾(lv)(lv)(lv)(lv)(lv)筒(tong)(tong)(tong)(tong)(tong)生產廠家(jia)，結構緊湊，占(zhan)地(di)面(mian)積小，便于(yu)(yu)(yu)換(huan)筒(tong)(tong)(tong)(tong)(tong)，但清(qing)灰時，上(shang)層濾(lv)(lv)(lv)(lv)(lv)筒(tong)(tong)(tong)(tong)(tong)清(qing)落(luo)的(de)(de)粉(fen)塵(chen)(chen)(chen)沉落(luo)于(yu)(yu)(yu)下層濾(lv)(lv)(lv)(lv)(lv)筒(tong)(tong)(tong)(tong)(tong)上(shang)，難(nan)(nan)以清(qing)除(chu)。水(shui)(shui)平(ping)安(an)(an)(an)裝(zhuang)，下層濾(lv)(lv)(lv)(lv)(lv)筒(tong)(tong)(tong)(tong)(tong)上(shang)部的(de)(de)粉(fen)塵(chen)(chen)(chen)更(geng)難(nan)(nan)清(qing)除(chu)。傾(qing)斜安(an)(an)(an)裝(zhuang)濾(lv)(lv)(lv)(lv)(lv)筒(tong)(tong)(tong)(tong)(tong)除(chu)塵(chen)(chen)(chen)器適于(yu)(yu)(yu)中(zhong)小除(chu)塵(chen)(chen)(chen)系統非粘性、低濃度、粒粗粉(fen)塵(chen)(chen)(chen)除(chu)塵(chen)(chen)(chen)用(yong)，也適于(yu)(yu)(yu)一些老式(shi)袋除(chu)塵(chen)(chen)(chen)器的(de)(de)改造用(yong)。

除塵濾筒在國內發展(zhan)前景

濾筒是我國的除塵設備在除塵濾筒技術方面與國外相比雖有一定差距，產品性能不是很穩定、適應性較差，3米濾筒廠家，但是隨著在環保方面的要求越來越高，所制定的相關標準也越來越嚴格，所有企業使用國外除塵設備是不現實的，濾筒，因此我國生產除塵設備的企業將會擁有更大的市場，同時相應的競爭也會加劇，粉塵濾芯生產廠家，這對我國除塵設備的發展也起到了積極的促進作用。

濾筒的特點與選用

濾(lv)筒(tong)的外(wai)形尺寸可(ke)分為兩類：一類的粗(cu)短濾(lv)筒(tong)，這(zhe)是(shi)目前這(zhe)各行(xing)業中用得較(jiao)普遍的濾(lv)筒(tong)，直徑通常(chang)有(you)324mm和(he)352mm兩種，長(chang)度(du)有(you)600mm和(he)660mm等，另一類是(shi)細(xi)長(chang)濾(lv)筒(tong)，這(zhe)是(shi)近年來(lai)開發出的替代濾(lv)袋的濾(lv)筒(tong)，直徑有(you)127mm、133mm、159mm、162mm，長(chang)度(du)可(ke)以(yi)達(da)到(dao)2m。

濾(lv)筒(tong)的(de)外(wai)壁(bi)(bi)形式有兩種(zhong)(zhong)(zhong)：一種(zhong)(zhong)(zhong)是內(nei)外(wai)壁(bi)(bi)均用(yong)鍍(du)鋅金屬網(wang)或不銹鋼網(wang)保(bao)(bao)護(hu)，通常(chang)用(yong)于空氣過濾(lv)，另一種(zhong)(zhong)(zhong)是外(wai)壁(bi)(bi)采用(yong)扎帶保(bao)(bao)護(hu)，便于清灰(hui)，通常(chang)用(yong)于粉塵過濾(lv)。
