防爆電加熱器概述
防爆電(dian)(dian)加(jia)熱器(qi)是一種(zhong)國(guo)際流行(xing)的(de)高品質(zhi)長壽(shou)命電(dian)(dian)加(jia)熱設備。用于對流動的(de)液態(tai)、氣(qi)態(tai)介(jie)質(zhi)的(de)升溫、保溫、加(jia)熱。當(dang)加(jia)熱介(jie)質(zhi)在壓力作用下通(tong)過電(dian)(dian)加(jia)熱器(qi)加(jia)熱腔,采用流體熱力學原(yuan)理均勻(yun)地(di)帶走電(dian)(dian)熱元件工作中所產(chan)生的(de)巨大熱量(liang),使被加(jia)熱介(jie)質(zhi)溫度達(da)到用戶工藝要求。
防爆(bao)電加(jia)熱器(qi)工作原(yuan)理
防爆電(dian)(dian)(dian)加(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器是(shi)一種消耗電(dian)(dian)(dian)能轉換為熱(re)(re)(re)(re)(re)(re)(re)(re)能,來對需(xu)加(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)物(wu)(wu)料進(jin)(jin)行加(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)。在工(gong)(gong)作中低(di)溫(wen)流(liu)體(ti)介質(zhi)通過(guo)管道(dao)在壓(ya)力作用下(xia)進(jin)(jin)入其輸(shu)(shu)入口(kou),沿著電(dian)(dian)(dian)加(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)容(rong)器內部特(te)定換熱(re)(re)(re)(re)(re)(re)(re)(re)流(liu)道(dao),運用流(liu)體(ti)熱(re)(re)(re)(re)(re)(re)(re)(re)力學(xue)原理設計的(de)路(lu)徑,帶走(zou)電(dian)(dian)(dian)熱(re)(re)(re)(re)(re)(re)(re)(re)元件工(gong)(gong)作中所產(chan)生的(de)高溫(wen)熱(re)(re)(re)(re)(re)(re)(re)(re)能量(liang),使被加(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)介質(zhi)溫(wen)度升高,電(dian)(dian)(dian)加(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器出(chu)口(kou)得(de)到(dao)工(gong)(gong)藝(yi)要求的(de)高溫(wen)介質(zhi)。電(dian)(dian)(dian)加(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器內部控制系統(tong)依據(ju)輸(shu)(shu)出(chu)口(kou)的(de)溫(wen)度傳感器信號(hao)自動調節電(dian)(dian)(dian)加(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器輸(shu)(shu)出(chu)功率,使輸(shu)(shu)出(chu)口(kou)的(de)介質(zhi)溫(wen)度均勻;當(dang)發熱(re)(re)(re)(re)(re)(re)(re)(re)元件超溫(wen)時(shi),發熱(re)(re)(re)(re)(re)(re)(re)(re)元件的(de)獨立(li)的(de)過(guo)熱(re)(re)(re)(re)(re)(re)(re)(re)保護裝置立(li)即切斷加(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)電(dian)(dian)(dian)源,避免加(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)物(wu)(wu)料超溫(wen)引起結(jie)焦、變質(zhi)、碳化,嚴重時(shi)導致發熱(re)(re)(re)(re)(re)(re)(re)(re)元件燒壞,有效延長電(dian)(dian)(dian)加(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器使用壽(shou)命。
