    防爆電伴熱帶防凍保溫技術是一種新型的由電能直接轉化為熱能的供暖技術,補充由于管道外殼內外溫差引起的熱散失。要達到管道伴熱保溫的目的,只需要提供給管路損失的熱量,保持管道內流體的熱量平衡,就可維持其溫度基本不變。防爆電伴熱帶系統(tong)就是提供給管路損失(shi)的熱量,維持其(qi)溫度基本(ben)不變(bian)。

    冬(dong)天(tian)化工(gong)廠管(guan)(guan)(guan)線防凍,主要(yao)考慮的(de)就(jiu)是(shi)工(gong)藝正(zheng)常運轉,使(shi)其(qi)正(zheng)常工(gong)作(zuo)。管(guan)(guan)(guan)道里面的(de)介質(zhi),在(zai)冬(dong)天(tian)溫(wen)度低的(de)情況下是(shi)否影響工(gong)藝要(yao)求,主要(yao)方法,就(jiu)是(shi)安裝防爆電(dian)伴(ban)(ban)(ban)(ban)熱(re)(re)(re)(re)帶,用巖綿包(bao)裹保(bao)(bao)(bao)溫(wen),或是(shi)內加盤(pan)(pan)管(guan)(guan)(guan)加熱(re)(re)(re)(re)。管(guan)(guan)(guan)道外(wai)面纏繞蒸(zheng)汽伴(ban)(ban)(ban)(ban)熱(re)(re)(re)(re)管(guan)(guan)(guan),還有保(bao)(bao)(bao)溫(wen)棉,儲桶內有蒸(zheng)汽盤(pan)(pan)管(guan)(guan)(guan),由于(yu)介質(zhi)是(shi)脂肪酸(suan)很容易(yi)凝固,有時候夏天(tian)也(ye)有管(guan)(guan)(guan)道堵塞(sai),尤其(qi)是(shi)閥門處,經常要(yao)用蒸(zheng)汽吹掃。冬(dong)季(ji)防凍有幾種(zhong)方式,一是(shi)加伴(ban)(ban)(ban)(ban)熱(re)(re)(re)(re)和保(bao)(bao)(bao)溫(wen)(伴(ban)(ban)(ban)(ban)熱(re)(re)(re)(re)有兩種(zhong)電(dian)伴(ban)(ban)(ban)(ban)熱(re)(re)(re)(re)和蒸(zheng)汽伴(ban)(ban)(ban)(ban)熱(re)(re)(re)(re)。)二是(shi)放空,有些(xie)不用的(de)管(guan)(guan)(guan)線及時排(pai)空并吹掃干凈。三(san)是(shi)在(zai)低點作(zuo)小排(pai)放或打循環保(bao)(bao)(bao)證流(liu)動(艾(ai)克森不建議使(shi)用,此法十分(fen)不經濟)管(guan)(guan)(guan)道伴(ban)(ban)(ban)(ban)熱(re)(re)(re)(re)常用有蒸(zheng)汽伴(ban)(ban)(ban)(ban)熱(re)(re)(re)(re)、電(dian)伴(ban)(ban)(ban)(ban)熱(re)(re)(re)(re)、熱(re)(re)(re)(re)水伴(ban)(ban)(ban)(ban)熱(re)(re)(re)(re)。

    作為傳統伴熱的‘領軍’方式的蒸汽伴熱,此法使用時候雖然能夠起到管道伴熱防(fang)凍的目的,但是缺陷明顯,使用這種方式(shi),一旦蒸汽伴熱忽(hu)然中斷,就會出現冷凝現象,十分不利于管線防(fang)凍。

    熱(re)(re)水(shui)伴(ban)(ban)熱(re)(re)也(ye)一(yi)樣,此法(fa)先(xian)(xian)期(qi)投資比較大,在(zai)冬(dong)季還(huan)容易(yi)出現炸(zha)管(guan)和炸(zha)鍋危險,浪費水(shui)資源還(huan)污染(ran)環境,一(yi)個鍋爐水(shui)伴(ban)(ban)熱(re)(re)系統一(yi)個采暖(nuan)季起(qi)碼要(yao)燃燒200噸燃煤,嚴重污染(ran)空(kong)氣(qi),從(cong)環保角度上說此法(fa)早(zao)晚被‘淘汰(tai)’,電(dian)伴(ban)(ban)熱(re)(re)作(zuo)為(wei)(wei)新型的(de)管(guan)道伴(ban)(ban)熱(re)(re)手段越來(lai)越受到青睞,國家(jia)也(ye)正(zheng)大力推薦此種(zhong)節(jie)能、環保的(de)管(guan)線(xian)防凍方式(shi)。只要(yao)先(xian)(xian)期(qi)安裝一(yi)條防爆電(dian)伴(ban)(ban)熱(re)(re)帶,安裝啟動(dong)之后即不用(yong)人(ren)為(wei)(wei)控制,也(ye)不用(yong)專門配備維護人(ren)員,自動(dong)調節(jie)溫度。是十(shi)分(fen)安全可靠(kao)的(de)管(guan)線(xian)電(dian)伴(ban)(ban)熱(re)(re)產品(pin),運營費用(yong)也(ye)十(shi)分(fen)低(di)廉,更符合如今國情。
