防爆電加熱器概述
防爆(bao)電(dian)加熱(re)(re)器是一種國際流(liu)行(xing)的(de)高品質長壽(shou)命電(dian)加熱(re)(re)設備。用(yong)于對流(liu)動的(de)液態、氣態介(jie)質的(de)升溫(wen)、保溫(wen)、加熱(re)(re)。當加熱(re)(re)介(jie)質在壓力作用(yong)下通過電(dian)加熱(re)(re)器加熱(re)(re)腔(qiang),采用(yong)流(liu)體熱(re)(re)力學原(yuan)理(li)均勻地(di)帶走(zou)電(dian)熱(re)(re)元件(jian)工(gong)作中所產生(sheng)的(de)巨大熱(re)(re)量,使被加熱(re)(re)介(jie)質溫(wen)度達(da)到用(yong)戶(hu)工(gong)藝要求。
防爆電加(jia)熱器工作原(yuan)理(li)
防爆電(dian)加熱(re)(re)器(qi)是一種消耗電(dian)能轉換為(wei)熱(re)(re)能,來(lai)對需(xu)加熱(re)(re)物料(liao)進行加熱(re)(re)。在工(gong)作(zuo)中低溫(wen)(wen)流(liu)體(ti)介質(zhi)通(tong)過管道(dao)在壓力(li)作(zuo)用(yong)下進入其輸(shu)(shu)入口,沿著電(dian)加熱(re)(re)容(rong)器(qi)內部特定換熱(re)(re)流(liu)道(dao),運用(yong)流(liu)體(ti)熱(re)(re)力(li)學原理(li)設計的路徑,帶走電(dian)熱(re)(re)元(yuan)件工(gong)作(zuo)中所(suo)產生的高(gao)溫(wen)(wen)熱(re)(re)能量,使被加熱(re)(re)介質(zhi)溫(wen)(wen)度升高(gao),電(dian)加熱(re)(re)器(qi)出口得(de)到工(gong)藝要求的高(gao)溫(wen)(wen)介質(zhi)。電(dian)加熱(re)(re)器(qi)內部控(kong)制系統依(yi)據輸(shu)(shu)出口的溫(wen)(wen)度傳感器(qi)信號自(zi)動調(diao)節電(dian)加熱(re)(re)器(qi)輸(shu)(shu)出功率,使輸(shu)(shu)出口的介質(zhi)溫(wen)(wen)度均勻;當發熱(re)(re)元(yuan)件超溫(wen)(wen)時(shi),發熱(re)(re)元(yuan)件的獨立的過熱(re)(re)保護裝置立即切斷加熱(re)(re)電(dian)源(yuan),避免加熱(re)(re)物料(liao)超溫(wen)(wen)引起(qi)結焦、變質(zhi)、碳化,嚴(yan)重時(shi)導致發熱(re)(re)元(yuan)件燒壞,有效延長(chang)電(dian)加熱(re)(re)器(qi)使用(yong)壽命。
