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。防爆電伴熱帶系統就(jiu)是提(ti)供(gong)給管(guan)路損(sun)失的(de)熱量,維(wei)持其(qi)溫(wen)度基本不變(bian)。
冬(dong)天(tian)化工(gong)廠管(guan)(guan)線防(fang)凍，主要(yao)考慮的就是(shi)(shi)(shi)工(gong)藝正常運轉，使其(qi)(qi)正常工(gong)作(zuo)。管(guan)(guan)道(dao)(dao)里面(mian)的介(jie)質，在(zai)冬(dong)天(tian)溫(wen)度低的情況下是(shi)(shi)(shi)否影響工(gong)藝要(yao)求，主要(yao)方法(fa)，就是(shi)(shi)(shi)安裝(zhuang)防(fang)爆電(dian)伴(ban)(ban)熱(re)(re)(re)(re)帶(dai)，用(yong)巖綿包裹保溫(wen)，或是(shi)(shi)(shi)內加(jia)盤管(guan)(guan)加(jia)熱(re)(re)(re)(re)。管(guan)(guan)道(dao)(dao)外(wai)面(mian)纏繞蒸(zheng)汽(qi)伴(ban)(ban)熱(re)(re)(re)(re)管(guan)(guan)，還有(you)(you)(you)(you)保溫(wen)棉，儲桶內有(you)(you)(you)(you)蒸(zheng)汽(qi)盤管(guan)(guan)，由于介(jie)質是(shi)(shi)(shi)脂肪(fang)酸(suan)很容易凝固，有(you)(you)(you)(you)時候夏天(tian)也有(you)(you)(you)(you)管(guan)(guan)道(dao)(dao)堵(du)塞，尤其(qi)(qi)是(shi)(shi)(shi)閥門(men)處，經常要(yao)用(yong)蒸(zheng)汽(qi)吹(chui)掃。冬(dong)季防(fang)凍有(you)(you)(you)(you)幾(ji)種方式，一(yi)是(shi)(shi)(shi)加(jia)伴(ban)(ban)熱(re)(re)(re)(re)和保溫(wen)（伴(ban)(ban)熱(re)(re)(re)(re)有(you)(you)(you)(you)兩(liang)種電(dian)伴(ban)(ban)熱(re)(re)(re)(re)和蒸(zheng)汽(qi)伴(ban)(ban)熱(re)(re)(re)(re)。）二是(shi)(shi)(shi)放空，有(you)(you)(you)(you)些不用(yong)的管(guan)(guan)線及時排(pai)空并吹(chui)掃干凈。三是(shi)(shi)(shi)在(zai)低點(dian)作(zuo)小排(pai)放或打循環(huan)保證流動(dong)（艾克森不建議使用(yong)，此法(fa)十(shi)分不經濟(ji)）管(guan)(guan)道(dao)(dao)伴(ban)(ban)熱(re)(re)(re)(re)常用(yong)有(you)(you)(you)(you)蒸(zheng)汽(qi)伴(ban)(ban)熱(re)(re)(re)(re)、電(dian)伴(ban)(ban)熱(re)(re)(re)(re)、熱(re)(re)(re)(re)水伴(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凍的(de)目的(de)，但(dan)是缺(que)陷明顯，使(shi)用這種方式，一(yi)旦(dan)蒸汽伴熱忽(hu)然中斷，就會出現冷(leng)凝現象，十分(fen)不(bu)利于(yu)管線防凍。
熱水(shui)伴(ban)(ban)(ban)熱也(ye)(ye)一(yi)樣，此(ci)法(fa)先期投資比較大(da)，在冬(dong)季(ji)還容(rong)易出現炸管和炸鍋危(wei)險，浪費水(shui)資源(yuan)還污染環(huan)境(jing)，一(yi)個(ge)鍋爐水(shui)伴(ban)(ban)(ban)熱系統(tong)一(yi)個(ge)采暖季(ji)起碼要(yao)(yao)燃燒200噸燃煤，嚴重(zhong)污染空氣，從環(huan)保(bao)角度上說此(ci)法(fa)早晚被‘淘汰’，電伴(ban)(ban)(ban)熱作為(wei)新型的管道伴(ban)(ban)(ban)熱手段(duan)越來越受到青(qing)睞(lai)，國(guo)家(jia)也(ye)(ye)正大(da)力推(tui)薦此(ci)種節能、環(huan)保(bao)的管線(xian)防(fang)凍(dong)方式(shi)。只(zhi)要(yao)(yao)先期安(an)裝(zhuang)一(yi)條防(fang)爆電伴(ban)(ban)(ban)熱帶，安(an)裝(zhuang)啟(qi)動之后即(ji)不(bu)用人(ren)為(wei)控制(zhi)，也(ye)(ye)不(bu)用專(zhuan)門(men)配備維護人(ren)員，自動調(diao)節溫度。是(shi)十分安(an)全(quan)可靠的管線(xian)電伴(ban)(ban)(ban)熱產品，運(yun)營費用也(ye)(ye)十分低廉(lian)，更符(fu)合(he)如今國(guo)情。
