    信息來源://wl132.cn/ 發布時間:2013/12/30 8:49:21 點擊數: Tags: 過濾網設備

空氣過濾器濾網與(yu)傳統(tong)的過(guo)濾(lv)(lv)(lv)設備相比是一(yi)種新(xin)型的過(guo)濾(lv)(lv)(lv)設備,空(kong)(kong)氣過(guo)濾(lv)(lv)(lv)器(qi)濾(lv)(lv)(lv)網(wang)是將液體(ti)中的顆粒在一(yi)定條件下自動地(di)過(guo)濾(lv)(lv)(lv)除(chu)去的分(fen)離過(guo)濾(lv)(lv)(lv)裝置。空(kong)(kong)氣過(guo)濾(lv)(lv)(lv)器(qi)濾(lv)(lv)(lv)網(wang)自動化程度高(gao);壓(ya)力損(sun)失小;不必進行人(ren)工除(chu)去濾(lv)(lv)(lv)渣,多數高(gao)效空(kong)(kong)氣過(guo)濾(lv)(lv)(lv)器(qi)在清洗時可以不間斷(duan)供水,空(kong)(kong)氣過(guo)濾(lv)(lv)(lv)器(qi)濾(lv)(lv)(lv)網(wang)適用(yong)于工業、農業、市政、海水淡(dan)化過(guo)程等(deng)的分(fen)離過(guo)濾(lv)(lv)(lv)。

下面(mian)給大(da)家介紹(shao)幾(ji)種空氣過(guo)濾(lv)器濾(lv)網的清(qing)污方式。

(1)刷式空氣(qi)過濾(lv)器(qi)濾(lv)網(wang)

刷式空(kong)氣(qi)過(guo)(guo)濾(lv)(lv)(lv)(lv)器(qi)濾(lv)(lv)(lv)(lv)網(wang)(wang)(wang)為一(yi)種(zhong)適用于惡劣(lie)環(huan)境的(de)空(kong)氣(qi)過(guo)(guo)濾(lv)(lv)(lv)(lv)器(qi)濾(lv)(lv)(lv)(lv)網(wang)(wang)(wang),對于不同的(de)使用要(yao)求可配(pei)備3500微米-200微米的(de)濾(lv)(lv)(lv)(lv)網(wang)(wang)(wang)。過(guo)(guo)濾(lv)(lv)(lv)(lv)器(qi)的(de)清洗(xi)過(guo)(guo)程由一(yi)個(ge)(ge)時刻(ke)監(jian)測過(guo)(guo)濾(lv)(lv)(lv)(lv)網(wang)(wang)(wang)兩側壓差的(de)壓差開(kai)關(guan)來(lai)啟動(dong),通(tong)常情況下(xia)(xia)壓差開(kai)關(guan)的(de)預(yu)設值是0.05Mpa。當過(guo)(guo)濾(lv)(lv)(lv)(lv)器(qi)濾(lv)(lv)(lv)(lv)網(wang)(wang)(wang)兩側壓差達到預(yu)設值時,過(guo)(guo)濾(lv)(lv)(lv)(lv)器(qi)將開(kai)始自清洗(xi)過(guo)(guo)程,整(zheng)個(ge)(ge)自清洗(xi)過(guo)(guo)程包含兩個(ge)(ge)步驟(zou):打開(kai)位于過(guo)(guo)濾(lv)(lv)(lv)(lv)器(qi)端蓋上(shang)的(de)排污閥(fa);電(dian)機(ji)帶動(dong)濾(lv)(lv)(lv)(lv)網(wang)(wang)(wang)內的(de)不銹鋼刷轉動(dong),被濾(lv)(lv)(lv)(lv)網(wang)(wang)(wang)所捕(bu)捉的(de)雜(za)質被鋼刷刷下(xia)(xia)并從排污閥(fa)排出。整(zheng)個(ge)(ge)清洗(xi)過(guo)(guo)程耗時約20秒,清洗(xi)時系統不斷流,過(guo)(guo)濾(lv)(lv)(lv)(lv)器(qi)的(de)整(zheng)個(ge)(ge)運行過(guo)(guo)程由隨機(ji)配(pei)備的(de)一(yi)個(ge)(ge)控(kong)制(zhi)箱來(lai)控(kong)制(zhi)。

(2)盤式空氣過濾器濾網

刮盤式空氣過(guo)濾(lv)(lv)(lv)器(qi)濾(lv)(lv)(lv)網(wang)不僅可(ke)應用(yong)于低粘度的(de)含固液體(ti)分(fen)離,還(huan)可(ke)以用(yong)于高粘度的(de)含固液體(ti)分(fen)離。工作過(guo)程如(ru)下:過(guo)濾(lv)(lv)(lv):需過(guo)濾(lv)(lv)(lv)流(liu)體(ti)被(bei)壓入過(guo)濾(lv)(lv)(lv)器(qi)內腔,流(liu)體(ti)自內而外(wai)穿過(guo)濾(lv)(lv)(lv)芯(xin),大于過(guo)濾(lv)(lv)(lv)元件縫隙(xi)的(de)雜質(zhi)被(bei)滯留在(zai)濾(lv)(lv)(lv)網(wang)的(de)內表面(mian),澄清流(liu)體(ti)穿過(guo)縫隙(xi)由出(chu)液口排出(chu)。自清洗(xi):一個(ge)帶(dai)有(you)彈簧的(de)清洗(xi)圓(yuan)盤,在(zai)濾(lv)(lv)(lv)芯(xin)內部上下運(yun)動(dong)來除去聚(ju)集在(zai)濾(lv)(lv)(lv)網(wang)內表面(mian)的(de)濾(lv)(lv)(lv)渣。

在清(qing)洗(xi)圓盤(pan)下行過(guo)(guo)程中(zhong),任何(he)殘留(liu)的濾(lv)渣(zha)都被(bei)驅至(zhi)集(ji)渣(zha)室,從(cong)而很容易被(bei)徹底除(chu)去。在清(qing)洗(xi)圓盤(pan)上行過(guo)(guo)程中(zhong),濾(lv)渣(zha)從(cong)濾(lv)網表面(mian)被(bei)去除(chu)。系(xi)統工藝流(liu)體(ti)(帶壓)驅濾(lv)渣(zha)穿(chuan)過(guo)(guo)清(qing)洗(xi)圓盤(pan)至(zhi)集(ji)渣(zha)室。

(3)吸污(wu)式空氣過濾器(qi)濾網工(gong)作原(yuan)理

空氣過(guo)(guo)(guo)濾(lv)(lv)器(qi)濾(lv)(lv)網(wang)過(guo)(guo)(guo)程(cheng)(cheng)(cheng):污(wu)水(shui)從(cong)過(guo)(guo)(guo)濾(lv)(lv)器(qi)進口進入,然后從(cong)里向外通過(guo)(guo)(guo)濾(lv)(lv)網(wang),比網(wang)孔大的雜(za)(za)質被(bei)攔(lan)截下來(lai)并積累(lei)在濾(lv)(lv)網(wang)的內(nei)表(biao)面形成(cheng)濾(lv)(lv)餅,這些濾(lv)(lv)餅同(tong)時(shi)能夠捕(bu)捉水(shui)中(zhong)的一(yi)些更細小的雜(za)(za)質。自清洗過(guo)(guo)(guo)程(cheng)(cheng)(cheng):壓差開關持續地檢測濾(lv)(lv)網(wang)內(nei)外的壓差,當達到預(yu)設值時(shi)將傳遞(di)信號(hao)到控(kong)(kong)制(zhi)箱啟(qi)動(dong)(dong)清洗循(xun)環。空氣過(guo)(guo)(guo)濾(lv)(lv)器(qi)濾(lv)(lv)網(wang)的清洗機(ji)構是作螺旋(xuan)式(shi)上下運動(dong)(dong)的吸(xi)污(wu)器(qi),它是空心結(jie)構,在它的軸線(xian)上按一(yi)定距離垂直均勻分(fen)布著若干個(ge)吸(xi)污(wu)管(guan)。吸(xi)污(wu)器(qi)與一(yi)個(ge)排污(wu)閥(fa)相通。在排污(wu)閥(fa)打開時(shi),空氣過(guo)(guo)(guo)濾(lv)(lv)器(qi)濾(lv)(lv)網(wang)內(nei)部(bu)(bu)水(shui)壓與外部(bu)(bu)大氣之(zhi)間形成(cheng)的壓差使吸(xi)污(wu)管(guan)產生強勁(jing)吸(xi)力,水(shui)流(liu)從(cong)濾(lv)(lv)網(wang)外向內(nei)反向高速(su)流(liu)動(dong)(dong)將雜(za)(za)質沖下來(lai)進入吸(xi)污(wu)器(qi)通過(guo)(guo)(guo)排污(wu)閥(fa)排出。吸(xi)污(wu)器(qi)由一(yi)個(ge)連(lian)有(you)絲桿裝置的雙向電機(ji)驅動(dong)(dong),按照固定的轉速(su)作螺旋(xuan)式(shi)的運動(dong)(dong),這樣(yang)多個(ge)吸(xi)嘴就能吸(xi)遍整(zheng)個(ge)濾(lv)(lv)網(wang)內(nei)表(biao)面,這個(ge)過(guo)(guo)(guo)程(cheng)(cheng)(cheng)大約(yue)需(xu)要半分(fen)鐘。在整(zheng)個(ge)反清洗過(guo)(guo)(guo)程(cheng)(cheng)(cheng)中(zhong),系統不(bu)斷流(liu),過(guo)(guo)(guo)濾(lv)(lv)器(qi)的整(zheng)個(ge)運行由程(cheng)(cheng)(cheng)序控(kong)(kong)制(zhi)器(qi)(PLC)來(lai)控(kong)(kong)制(zhi)完成(cheng)。

(4)轉臂式(shi)空氣(qi)過濾器濾網

轉(zhuan)臂式(shi)空氣過濾(lv)(lv)(lv)器(qi)(qi)濾(lv)(lv)(lv)網(wang)(wang)是一種集約(yue)化的(de)(de)(de)(de)(de)過濾(lv)(lv)(lv)器(qi)(qi),多個(ge)濾(lv)(lv)(lv)筒(tong)安(an)裝于(yu)(yu)一個(ge)過濾(lv)(lv)(lv)器(qi)(qi)筒(tong)體(ti)(ti)內(nei)(nei),結構緊湊。轉(zhuan)臂式(shi)空氣過濾(lv)(lv)(lv)器(qi)(qi)濾(lv)(lv)(lv)網(wang)(wang)用(yong)于(yu)(yu)去(qu)除低粘度介質中的(de)(de)(de)(de)(de)固體(ti)(ti)顆粒(li)。需過濾(lv)(lv)(lv)的(de)(de)(de)(de)(de)介質從(cong)內(nei)(nei)向(xiang)外流過過濾(lv)(lv)(lv)器(qi)(qi)的(de)(de)(de)(de)(de)楔形網(wang)(wang)濾(lv)(lv)(lv)筒(tong),固體(ti)(ti)顆粒(li)截留在(zai)濾(lv)(lv)(lv)筒(tong)內(nei)(nei)側(ce)(ce)。隨著(zhu)污染(ran)物的(de)(de)(de)(de)(de)增多,過濾(lv)(lv)(lv)器(qi)(qi)污染(ran)側(ce)(ce)和(he)(he)清潔側(ce)(ce)之間(jian)的(de)(de)(de)(de)(de)壓差(cha)增大。若壓差(cha)達到設置(zhi)(zhi)的(de)(de)(de)(de)(de)觸發壓差(cha)便開始自動(dong)反(fan)(fan)(fan)沖(chong)(chong)(chong)洗(xi)。反(fan)(fan)(fan)沖(chong)(chong)(chong)洗(xi)時(shi)(shi).齒(chi)輪電動(dong)機轉(zhuan)動(dong)欲(yu)清洗(xi)濾(lv)(lv)(lv)筒(tong)下面的(de)(de)(de)(de)(de)沖(chong)(chong)(chong)洗(xi)臂,進入(ru)反(fan)(fan)(fan)沖(chong)(chong)(chong)洗(xi)狀態的(de)(de)(de)(de)(de)濾(lv)(lv)(lv)筒(tong)的(de)(de)(de)(de)(de)原料液流被(bei)中斷。反(fan)(fan)(fan)沖(chong)(chong)(chong)洗(xi)閥開啟,濾(lv)(lv)(lv)液側(ce)(ce)和(he)(he)反(fan)(fan)(fan)沖(chong)(chong)(chong)洗(xi)管路(lu)之間(jian)的(de)(de)(de)(de)(de)壓降把一小部分濾(lv)(lv)(lv)液逆向(xiang)沖(chong)(chong)(chong)入(ru)欲(yu)清洗(xi)的(de)(de)(de)(de)(de)濾(lv)(lv)(lv)筒(tong)。空氣過濾(lv)(lv)(lv)器(qi)(qi)濾(lv)(lv)(lv)網(wang)(wang)聚積在(zai)濾(lv)(lv)(lv)筒(tong)內(nei)(nei)側(ce)(ce)的(de)(de)(de)(de)(de)污染(ran)顆粒(li)物被(bei)松(song)開并通過沖(chong)(chong)(chong)洗(xi)臂沖(chong)(chong)(chong)進反(fan)(fan)(fan)沖(chong)(chong)(chong)洗(xi)管路(lu)。每個(ge)濾(lv)(lv)(lv)筒(tong)的(de)(de)(de)(de)(de)反(fan)(fan)(fan)沖(chong)(chong)(chong)洗(xi)時(shi)(shi)間(jian)一過,反(fan)(fan)(fan)沖(chong)(chong)(chong)洗(xi)閥立即關閉(bi)。這樣所有濾(lv)(lv)(lv)筒(tong)被(bei)依次清洗(xi)。所有濾(lv)(lv)(lv)筒(tong)都被(bei)清洗(xi)后,反(fan)(fan)(fan)沖(chong)(chong)(chong)洗(xi)循(xun)環結束。轉(zhuan)臂式(shi)空氣過濾(lv)(lv)(lv)器(qi)(qi)濾(lv)(lv)(lv)網(wang)(wang)可以用(yong)來除去(qu)工業用(yong)水(shui)和(he)(he)海(hai)水(shui)中的(de)(de)(de)(de)(de)固體(ti)(ti)雜(za)質。轉(zhuan)臂式(shi)空氣過濾(lv)(lv)(lv)器(qi)(qi)濾(lv)(lv)(lv)網(wang)(wang)常用(yong)于(yu)(yu)保(bao)護(hu)重要設備,如冷卻系(xi)統(tong)、化學和(he)(he)水(shui)處理裝置(zhi)(zhi)等。

隨著(zhu)我(wo)國(guo)(guo)水(shui)(shui)資源的(de)(de)緊缺、工業的(de)(de)高速發(fa)展、環境的(de)(de)惡(e)化,空氣過濾(lv)器(qi)濾(lv)網(wang)必將(jiang)獲得越來越多的(de)(de)重視。前聯合國(guo)(guo)秘書長德(de)奎利亞爾曾講到(dao):“過去人類(lei)可怕(pa)的(de)(de)是戰爭,未來人類(lei)可怕(pa)的(de)(de)是淡水(shui)(shui)資源的(de)(de)緊缺”。我(wo)國(guo)(guo)的(de)(de)工業水(shui)(shui)重復利用(yong)和再(zai)生利用(yong)程度(du)較(jiao)低(di),用(yong)水(shui)(shui)工藝比較(jiao)落后,用(yong)水(shui)(shui)效率較(jiao)低(di)。
